Cow Arithmetic
Charles L. Anderson and John Holt
INTRODUCTION
Any man would like to "be his own boss". If he can't own his
own ranch, at least he would like to become a manager. Any success
ful manager sets certain goals for himself and his operation. For
example, he sets income goals based on the amount of money needed by
his family and required to run the ranch. He also sets production
goals for the number of calves he needs to produce on the ranch based
on proper pasture use.
To improve the ranch and to reach his goals, the manager has to
make many decisions. He has to decide how much money to borrow, how
many calves his ranch can produce and how and when to sell them. All
these decisions require some "figuring".
This publication was designed to be used as an instruction manual
to introduce vocational agricultural students and 4H club members to
some management techniques. We show how to make many bf the calculations
which managers use to help them make their day to day decisions.
Because managing money is so important in operating a ranch or
managing a home, we have included a section on credit. This section
introduces the topic of where to get money and how to determine what it
costs.
The examples and problems are based on managing a beef cattle opera
tion, but these same methods are used in managing any enterprise. Examples
are given in the text with a minimum explanation of why these approaches
to solving problems are used. The problems will show why these calcula
tions are a necessary part of management. Answers to the problems are
provided in the last section.
DETERMINING THE CALF CROP AND ITS VALUE
Q
The sale of calves is the major source of income on most ranches.
This section first shows how to calculate the percent calf crop and
then how to determine the total value of the calves sold.
Calculating Percent Calf Crop
The arithmetic involved in determining the percent calf crop is
very simple. You take the number of calves raised and divide this number
by the number of cows available for calving. For example, suppose there
are 700 calves raised, and 1000 cows were available for calving. You
would arrive at the percent calf crop as follows:
700 calves raised
700 calve raied .70 or 70% calf crop.
1000 cows available
Where most people make an error in calculating the percent calf crop
is in arriving at the number of cows that are available for calving. For
instance, if you had 950 cows and bred heifers in the herd at the begin
ning of the year, and you pregnancy tested this herd and found 150 head
open and sold them, you would not use the remaining 800 head as the number
of cows available for calving. You would use the original 950 head, for
they were all exposed to the bull and were intended to be the brood herd.
You can see that if you used the 800 remaining cows and heifers, you
would overstate or calculate a higher percent calf crop than you actually
3
haJ. n'r inxs.'nce if you r.aied 600 head of calves this year, your
pericue calf crop would be:
600 calves raised
S.63 or 63% calf crop,
950 cows available
it w.o)Ui not be:
600 calves raised
600 calves raised .75 or 75% calf crop.
800 cows available
On the other hand, if you had previously cut out some old cows for
sale and had kept them in an effort to fatten them before selling, you
would not include them as cows available for calving. True, you may
have exposed these cows to the bull in an effort to breed them so that
thea would fatten faster, but they were not intended for brood cows.
If your cow inventory looked like this:
A. 300 head Beginning inventory of cows
B. 100 Bred heifers transferred to herd
C. 400 head Total Supply
D. "I Open cows sold
:E. 30 Beef cows sold
F. 3 Cows died
,.. 317 Ending inventory of cows
H. 4U Head Total Disposition
the number of cowa available for calving would be 370. This would be
calcuLaced by the following procedure.
A. .i3(1 Head in beginning inventory
5. fTCO Head of bred heifers
400 Head
E. 'r! Head of beaf cows sold
370 Head Availabil for Calving
ijr.ltce th.at we have added the number of bred heifers to the beginning
inventory of cVuw and have subtracted the number of beef cows which were
oriclin.il intended for sale. We have not subtracted the number of open
cows sold nor the cows which died. If there were 250 calves raised
this year, the percent calf crop would be:
250 calves raised
= .675 or 68%
370 cows available
Problems in Calculating Percent Calf Crop
1. Calculate the percent calf crop if you had 100 calves and 150 cows
available for calving.
2. Calculate the percent calf crop if you sold 100 calves and kept 20
calves for replacements when there were 200 cows in the herd.
3. Calculate the percent calf crop with 300 cows in beginning inventory,
50 beef cows sold, 2 cows died, 150 calves sold and 50 calves saved
as replacements.
4. Calculate the percent calf crop from the following: 300 cows in
beginning inventory, 45 bred heifers added to herd, 30 open cows
sold, 40 beef cows sold, 3 cows died, 160 calves sold and 30 heifer
calves saved as replacements.
Determining Total Value of Calves
What is total value? It is the weight of the calves multiplied by
the price received per pound. In other words, the amount of money that
we receive from selling calves (or other cattle).
Why calculate the value of the calf crop? We do this to find out
how much money our cows will bring us in a year's time. Also because
(a) we have debts to pay such as rent, and (b) we must make this money
last for awhile. The money needs to last because we only sell calves
once a year, and we buy things all year long.
If we had 100 cows and they produced 80 calves weighing 400 pounds
each and we sold them for $25 per hundredweight, how much money would we
have?
5
40' pound calves 32,000 pounds
x 80 calves $.25 dollars/pound
32,000 pounds to be sold 160000
64000
$8,000.00 total value of calves
Problems
1. What if 80 calves sold for different prices for the steers and
heifers? What would be the total value of the calf crop if we
had:
45 steers 35 heifers
400 pound steers 350 pound heifers
calf price: (a) steers = $27/cwt.
(b) heifers = $25/cwt.
2. If you had a 200 cow herd and they had a 75% calf crop: (a) How ,
many calves would you have? (b) If the calves weighed 400 pounds
and sold for $30 per hundredweight, what would be the total value
of the calf crop?
INVENTORY VALUES
A manager must know the value of the things he is managing (some
times called assets); both for income taxes and to measure the growth
of che ranch from one year to the next. He must have an inventory to
do both of these things. An inventory is a list of the value of all
ii
assets and liabilities at a specified date. The manager takes an inven
tory ac the beginning and end of a yaar. For our example, we are going
to average beginning and ending values to obtain an average value for
the year, Before doing this, though, we must determine the values of i
individuals in the herd.
Growing atock snould be valued as close to market price as possible;
however, breeding otock should be valued at an average vilue for the qual
ity of the cows in the herd over a period of several years. This same
__iii4
" r '` L CF~ ._ ~ iS_Clyg~Li9~f;i1~Lr~~T __Z~~r~=;il;;;c4c~ L~=5~~ ~Vi* I
method should be used when placing a value on bulls in the breeding herd.
This means that growing stock (calves, heifers, steers and young bulls)
will come close to reflecting market conditions, and breeding stock will
remain at a fairly stable value  changed only to reflect a change in
quality.
Suppose at the beginning of the year you had saved 50 head of
yearold heifers from the past years calf crop, you intended to use
them as replacements in the breeding herd. These heifers averaged 500
pounds at the beginning of the year, and this type of heifer was selling
at the market for 25 a pound.
50 head X 500 lbs. X $.25 = $6,250.
Let's follow this group of heifers through the year and record the
transactions which occurred to arrive at a value at the end of the year.
You sold 5 of these heifers and 1 died, which would leave 44 heifers on
hand at the end of the year.
These heifers had gained 200 pounds during the year, and heifers
like them were selling for 234 a pound at the market. The value of
these heifers at the end of the year would be:
44 head X 70 lbs. X $.23 = $7,084.
The average value for your inventory of this group of heifers for
the year would be calculated by adding their value at the beginning of
the year plus the value at the end of the year and dividing the sum by 2.
$ 6,250
7,084 $13,334 4 2 $6,667.
$13,334
In calculating the inventory values of the breeding herd, you aver
age the sum of the beginning value and the ending value; but, in this case,
you will simply arrive at an average value of cows of the quality in your
herd and multiply this by the number of cows. This value on cows should
be your best evaluation of what this type cow would be worth from year to
year. You know that a certain cow might bring $125 at the market in one
year, and the same quality cow might have brought $165 at another time.
Some will be young cows; some will be older cows. The best figure that
you can obtain will be an educated "questimate." If we take the 2 values
mentioned above ($125 and $165) and sum them and take an average, your
herd would be worth $145 a head. If you counted 150 cows at the beginn
ing of the year, added 30 heifers, sold 15 cows and 3 cows died, your
inventory would look as follows:
Value
Head per Head Total Value
*Beginning Inventory 150 $145 $21,750
Transferred in 30 165 4,950
Total Supply
Sold

3 X
162 $145 $23,490
180 25,365
156 $22,620
$ 1,335
There are a lot of figures in the above table; however, the only two
figures you would use in calculating average inventory value would be the
Total Value of Beginning and Ending Inventories.
$21,750
23, 490 $45,240 T 2 $22,620
$45,240
In the above table, the last entry is depreciation. This is the
loss in value of the breeding herd during a year and is a method of
recovering this cost. The method used is known as "whole herd deprecia
tion." The following calculations show why this occurs. First, the 30
heifers which were added to the herd were valued at $165 when added and
at $145 in ending inventory. One hundred fortyfive dollars is the aver
age value of cows in the herd. The only time the average value per head
of cows in the breeding herd is changed is when there is a definite in
crease in quality of the herd. The value of heifers added to the herd
decreased by $20 each or a total of $600. Second, the 15 cows which were
sold, brought $20 each, less than their beginning value, or a total of
$300. Third, the cows that died had no value or a decrease of $145 each
for a total of $435. Adding the underscored values in this paragraph
will give the amount of depreciation, $1335.
In arriving at a value of inventory, livestock is not the only item
to be considered. We must take into consideration the values of machinery
and equipment, buildings and fences and land. Land will be considered
last, because it does not depreciate.
This is a good time to discuss depreciation. Depreciation is an
accounting or bookkeeping procedure for spreading the cost of a capital
item over the useful life of the item. For instance, suppose you buy a
truck for $3000, and you pay cash for the truck. Granted, you have paid
out the entire $3000 at one time; however, you expect to use this truck
for 5 years, and wish to know what the annual cost of the investment will
be in each year. There is a simple procedure to follow in determining
this cost. This is the straight line method of depreciation. There are
other methods of calculating this cost, but this is the simplest and most
commonly used method.
If the truck originally cost $3000, and you figure that it will be
worth $500 at the end of 5 year, you subtract the '500 (salvage value)
from the $3'000 (olgiunl coat) and divide by the number of years of
useful life (the number of years you plan to use the truck).
$3000
500 $2500 1 5 $500.
$2500
The above $500 is the annual straight line depreciation or annual capital
cost involved in the ornerahip of the truck.
You can use this 500 in figuring the inventory value of the truck
at the beginning or the end of any particular year. For example, if you
were interested in calculating the beginning and ending value, and the
average value of the truck the first year, the calculations would be as
follows: (Assume cruck purchased on first day of year.)'
Original cost $3,000
Depreciacion 500
Value at end of year $2,500
To calculate average value:
$3,000
2 500 $5,500 ; 2 $2,750
$ 5,500
To make the same calculations for the second year:
Beginning Value $2,500
Depreciation 500
Endin Value T2,000
To calculate: average value th. second year:
Beginning Value $2,500
Enatcu Value 2,o000 $4,500 2 $2,250
$4,500
The calculations on buildings and fences irould be made by the same
steps. The only difffernce would be in the lugth of life. B;!ildings
and fancej normally are expected to last for a longer period o1 time than
machinery and equipment.
When you are trying to calculate the average value of land for a
particular year, yo': can usually take the value at the beginning of the
period; because land does not normally depreciate. An exception to this
would be land appreciation (increase in value). If you had dug a canal
or planted grass during the year, you would have increased the value of
the land and should take this into consideration in calculating average
value of land in inventory.
First, let's assume that you have 500 acres of woodland at the
beginning of the year which you value at $30 per acre for cowland.
During the year you have cleared, ditched, diked and planted 100 acres
at a cost of 385 an acre. Your depreciation schedule would look like
this:
Beginning value of land (500 acres at $30) $15,000
Clearing, ditching, diL:in and plaiting (100 acres at $85) 8,500
Ending inventory value $23,500
To calculate average inventory value:
Beginnion value $15,000 $38,500 2 $19,250.
Ending value 23,500
$38,500
CALCULATING FEED COSTS
Feed costs are one of the biggest .1'.en items in ssaging a
ranch. The cost of rfariizi= grcaia is also part of the cost of feed
ing the cttle on the ranch. This ieaciou shows how to dete.ini hriat
the feed costs are per cow, then what feed costs are per pouid of beef
produced by the r:.ncti. Sin.. feed can be bou h in difieLent quanitities
in bulk (ton) or by thn haL (cwt,)  we show how to determine which
way to buy it. ThT.n ua polater' o .ve o on h:on t to ?l.uire the cost of
fertilizer.
Feed Cu ,. Per Cow
In calculatiit, feed co.t., pir cow, uwe first::determine the average
number of cows in tL.h herd using the beginning and ending inventories.
For example:
Beginning Inventory 1835 cows
Ending Inventory 1996 cows
3831
The average number of cows is 1916 (3831 2).
After calculating the average number of cows, we next determine
total feed costs. Suppose our ranch records show that purchased feed
last year was $17,212. If.we divide this cost by the average number of
cows, we get a cost of purchased feed per cow of $8.98. However, to
arrive at total direct feed costs, we should take into consideration the
cost of producing grass. For our purposes we will not consider labor,
machinery and equipment or taxes as contributing to this cost. These
important costs would have to be considered by a manager, but in order to
keep the problem simple, we will only consider money spent on seeds and
plants, fertilizerlime,.and feed. When these items are considered, our
feed cost per cow is quite different. The new feed cost would be approx
imarely $20. Thlu cost 13 obtained a follow':

Problems in Calculating Feerd Cos per Cow
1. What is the average of 10, 5, 7, 3, and 25?
2. Average 5, 13, 22 and 40.
3. What is the average number of cows on hand during a year when the
beginning inventory is 1050 and the ending inventory is 1100?
4. Figure the purchased feed cost per cow when the average number of
.cows on hand is 950 and the purchased feeds were $7600.
5. If we had a ranch record which showed a beginning inventory of 900
cows and an ending inventory of 1000 cows with these items of coats
(feed, $7600, fertilizer and lime, $7500 and seeds and plants of
$1000), what would the average feed cost per cow be?
Feed Cost Per Pound of Beef
In calculating the feed cost per pound of beef produced, feed costs
are determined the same way they were determined in calculating feed
post per cow. The problem here is in calculating pounds of beef produced.
When we calculate this figure, we are concerned with only the growing
stock. This includes calves, steers, young bulls and heifers which have
not entered the breeding herd. Cows and bulls in the breeding herd are
not considered.
Example: If at the
which weighed 550 pounds
pounds at the end of the
7,500 pounds of beef.
Ending inventory
Beginning inventory
If feed cost had been $8
beginning of the year you had 50 head of heifers
each, and this same group of heifers weighed 700
year; this group of heifers would have produced
50 head at 700 pounds 35,000 Ibs.
50 head at 550 pounds 27,500 "
7,500 lbs.
per head, the cost per pound of beef produced
would have been 5.33
50 head x $8 $400 $. 3 or
S$.0533 or 5.330
7500 lbs.
A situation you could cun into would be as follows;
Mo. Weight
Ending Inventory 1,333 696,566
Sales 939 392,815
Died 17 X
Eaten 
Transfer Out 405 305,442
Total Disposition 2.744 1,394,823
Purchases 27 14,598
Calves Raised 1,358 X
Beginning Inventory 1,359 688,681=
Total Supply 2,744 703,279
Total Produced 1,394,823
703,279
691,544
If you will use the $17,212 of purchased feed, the cost of purchased
feed per pount of beef produced will be 2.5C.
$17 212
$17,22 $.0248 or 2.53 per lb.
691,544 lbs.
In calculating the number of pounds produced, remember that you
always subtract the number of pounds you started with from the number of
pounds you had at the end of the period being considered. The difference
will be the number of pounds produced. The number of pounds you started
with will be found opposite Total Supply, and the number of pounds you had
at the end of the period will be Total Disposition.
Cwt. Vs. Ton
There are times when you are quoted feed prices by the hundred
pounds (cut,), while at other times the prices are given on a ton basis
for the same kind of feed. The most important fact to remember here is
that it takes 20 cwt, (twenty 100 lb. bags of feed) to equal a ton. For
the feed r.o bf the same price, the ton price should elual 20 tines the
cut. price.
If, for example, one feed dealer quoted you a price of $3.50 per
cwt. on 412 cottonseed meal, and another quoted a price in bags at
$75 per ton, which should you buy? Simply multiply the cwt. price by
20. If the result is less than $75, buy from the dealer quoting the
$3.50 per cwt. If the result is larger, buy from the dealer quoting
the ton price. In this case you would buy from the dealer quoting
the cwt. price of $3.50.
$3.50 X 20 $70 per ton
You could also make the comparison by dividing the $75 by 20.
$75 4 20 $3.75 per cwt.
Probably as important as knowing how to convert cwt. prices to ton
prices is knowing what you are buying. If you are quoted prices such as
$3.50 per cwt. and $3.25 per cwt. for cottonseed meal, be sure the dealers
are talking about the same product. When you are buying cottonseed meal,
you are buying protein; and the percentage of protein could be different.
Of course if they are both quoting prices on 41% protein meal, you would
purchase the meal at $3.25. However, if the dealer quoting $3.50 was
planning to deliver 41% meal and the dealer quoting $3.25 had 36% pro
tein meal, you should do some calculating before you make a decision.
Since your main reason for purchasing cottonseed meal is for the
protein content, you should calculate the cost per pound of protein.
There are 36 pounds of protein in 100 pounds of 36% meal. If you will
divide the $3.25 by 36 you will see that this protein costs you 9t per
pound.
There are 41 pounds of protein in 100 pounds of 41% meal. Divide
the $3.50 by 41 and the results are the price per pound of protein 
8 1/24.

Fertilizer with Different Analyses
We know that nitrogen (N), phosphorus (P), and potassium (K) are
the ingredients in a fertilizer mix that makes plants grow. We also know
that grass pasture and clover pasture do not need the same kind of fertil
izer. Alo, fertilizer is sold in different blends such as 101010 and '
61020. Theenumbers 101010 mean that in 100 pounds of fertilizer, there
would be 10 pounds each of nitrogen, phosphorus, and potassium. Similarly,
a fertilizer with an analysis of 01020 would contain no N, 10 pounds of
P, and 20 pound of K.
I have seen some recommendations Jfr pastures indicating approximately
400 to '.0f pound, .'f 126b should be applied to grass pastures and 250 to
300 pound:rh of 0S24 applied to clover plus 100 pounds of muriate of pocast.
If we put on 500 pounds of 1266 per acre, we would be applying 60
pounds of nitrogen, 30 pounds of phosphcrus and 30 pounds of potassit~
per acre. If 1266 was $40 per ton apiLJ 500 pounds would cost 1lu
per acre ($40 x 500/2,000 = $10). Notice that this would only require
49 rounJ, of beef per acre to pay thei fertilizer cost, if calves were
$25 per hundredweight (40 pounds of extra beef x $25/cwt. $10).
On clover pasture, we might apply 300 pounds of 0824 at $35 per
ton. The cost would be:
$35 per ton 4 20 cwt./ton $1.75 per 100 pounds
300 pounds x $1.75 per cwt. $5.25 per acre to apply 300 lbs.
of 0824.
If muriate of potash cost $3.00/cwt., we would have ($5.25 + $3.00)
$8.25 per acre on fertilizer for clover.
jEamgle: If 1266 was $45 per ton and 1688 was $60 per ton,
which one would be the cheapest? The cost per pound of plant nutrient
is the thing to base a decision on. The cost per pound of nutrient is
the same.
12 + 6 + 6 = 24 $45 4 20 $2.25/cwt. $2.25 T 24 $.093/1bujnutrient
16 + 8 + 8 32 $60 4 20 $3.00/cwt. $3.00 T 32 $.093/1b. nutrient
However, this method would be of little use if the pasture needed nitrogen
and the fertilizer 2alysis was 01020. The point is to be sure that the
fertilizer you are applying will provide the recommended amounts of N, P,
and K.
Problem; Suppose soil test recommendations call for 60 pounds of
N, 30 pounds of P, and 30 pounds of K (500 pounds per acre of 1266).
If 1266 fertilizer is $50 per ton and 1688 is $60 per ton, which one
should you apply? Why?
Conclusions
1. Determine the amount of nutrients recommended per acre.
2. Use a blend which will provide approximately the desired amount of
N, P, and K per acre.
3. Use the cheapest fertilizer on a per pound of nutrient basis, not
per bag or per ton.
4. Estimate your fertilizer needs for a year and get a bid (in bulk,
if you can handle it this way) for the year's supply.
5. Generally speaking, a higher analysis fertilizer will be cheaper
on a per pound nutrient basis.
STOCKING RATES
An animal unit is a term that ranchers use to make it easier to
figure out what the stocking rate is. We adjust the number of steer,
heifers, and calves so that they equal the number of cows it would take
to eat that same amount of grass.
Animal Units (a.u.)
1 cow 1.0 a.u.
1 cow and calf 1.25 ,a.u.
1 bull 1.25 a.u.
1 steer .5 a.u.
1 heifer .5 a.u.
1 calf .25 a.u.
I horse 2. a.u.
Calculating the number of animal units allows us to compare the
amount of grass that the cows and calyas in one pasture will eat which
tha amount that steers and heifers in another paatura will eat.
For example, a maun ight have two pastures about 100 acres each.
They are just about the same, and he wants to run 80 cows and calves
in one pasture and 200 steers and heifers in the other. He wonders which
will eat the pasture down the fastest. But how doa! he compare cowa
with calves to steers and heifers? Re uses "animal units."
From the table above:
80 coe 80 a.u,
+30 calves (1/4 a.u. each) 20 a.u.
100 a.u. frcm SO cows with calves
100 steers (1/2 a.u. each) = 50 a.u.
+100 heifers (1/2 a.u. each) 50 a.u.
100 a.u, from 200 steers and heifers
Problems
1. How many animal units would you have if you had:
8 bulls 40 heifers
5 dry cows 10 steers
1 Scows and calves 4 horses
2. If we had 210 a.u. and 500 acres, what is the stocking rate in acres
per animal unit?
3. How many animal units are there in a 200 cow breeding herd?
Assume:
(a) 70% calf crop
(b) 25 cows per bull
(c) cows replaced after 5 years (20% replacements)
(d) 2 horses
4. Using the answer to problem 3, and a stocking rate of 2.23 acres/a.u.,
how many acres of improved pasture will be necessary to maintain a
200 cow breeding herd?
SELLING WISELY
Producing good heavy calves is only half the battle in managing a
ranch. They must be sold wisely. The manager can sell at the ranch or
at an auction in town. The amount of weight loss (shrinkage) and the
trucking costs are two of the main things he must know. This section
shows how they can be calculated.
Calculating Shrinkage
Shrinkage is the amount of weight lost by cattle berwean the ranch
pens and the market. Cattle are frequently bought and sold .Wih a
"pencil .shrink". That is, the buyer weighs them at the ranch pens, and
deducts a percentage figure (3% for example) from the ranch weight. This
1. suppuoed co be the same as the amount of weight the cattle would lose
during the ride to market.
CalLtl on different types of pasture shrink different amounts, and
the farther it is to market, the more shrinkage. However, if the cattle
have been penned overnight, they have already lost some weight. Therefore,
in selling cattle, a man needs to understand how to figure shrinkage, so
that he can do a better job of selling his cattle.. For example, a lower
price received per pound for cattle at the ranch with no "pencil shrink"
deducted ,can be more profitable than a higher price per pound when the
buyer is allowed to subtract too many pounds for shrinkage.
If your steer calves weighed 400 pounds at the ranch and they would
shrink 3% on the trip to market, how many pounds of beef would you sell?
400 pound steer
x .03 weight loss in shipment (shrinkage)
12.00 pounds weight lost from ranch to market
400 pounds at ranch
12 pounds weight loss
388 pounds the steer would weigh at market
The o.:llowing tables can help you decide where and how to sell. In
ITabi 1 suppose that a buyer offers you $20.00 per hundred pounds for
your steer calves with a 3 percent shrink allo's.ane. Looking at $20.00
under column 1, headed Offer and at column 3, headed 3%, you.will receive
$19.40 for your cattle.
If we want $20.00 for our cattle, we mi.hi reu.iCe thC offer ab,,uve, and
Ship to mn.'ket. Looking'at Table 2 under cilurn 1, headed Asing if catcli
shrink 3 percent during shipment, the market .price will have to be $2'1,62 it
order to compensate for shrink.

Problems
1. Suppose you have two offers for your 400 pound steers; (a) $24.50/cwt.
without a shrink deducted, and (b) $25.00/cwt. with a 4% shrink.
Which will make you the most money?
2. If the buyer offers $30 per hundredweight with a 4% shrink, how much
will you really receive per hundredweight (Table 1)?
3. If you are asking $30.00 per hundredweight for your steers and they
will shrink 2% on the ride to town, how much will the price per
hundredweight have to be to net you $30.00 per hundredweight?
4. If yc.r ca3lve weighed 450 pounds, and one buyer offered you $3G.G0
per :i .:i.edweight with a 2 percent shrink; another buyer offered
you $29.25 with no shrink, which offer would you take?
If you know how to figure shrink, and about how much your cattle will
shrink being hauled to different markets, you can do a good job of selling
your cattle. Hauling costs and commission charges should also be con
sidered if the cattle are hauled to market and sold on a cosmis~uon.
Figuring Trucking Costs
knent considering trucking costs, there are 2 basic e~thod3 of
trucking or of transporting cattle which we should consider. We. shall
call them "hired trucking" and "owned trucking". Let's take a look at
"hired trucking" first. Next, we will look at costs involved in "owned
trucking" and try to compare the two.
Calculating the cost of hired trucking is easy. If the trucker
charges 50e per mile, and the market is 100 miles from your cowpens, just
multiply the 100 miles by the cost per mile (500).
100 miles X $.50 per mile $50 trip cost.
In other examples, we have talked about value per pnund and cost of
producing a pound of beef; and since we normally sell cattle by the pound,
let's calculate the cost of hired trucking by the pound. If we consider
the fact that a semitraller can safely haul 22 cows (chis ,uld depend
on length of trailer, of coUrae), ansd'te cows average 900 pounds; .we
can determine the number of pounds of beef hauled in one trailer of cows.
900 pounds X 22 cows = 19,8b0 pounds
In order to calculate the cost of trucking 'er pPound of beef, we need to
divide the $50 (cost per trip) by the number of pounds hauled.
$50 4 19,800 $.0025 or .25
If the cows sold at the market for 16.50C per pound, we see that the
trucking has reduced the amount we receive lor the cows from 16.50r to
16.25C. This cost can also be converted to a per head baais.
First, calculate value per head:
900 pounds X 16.50 = $148.50
Next, cost of trucking per head:
900 pounds X .25 = $2.25
When we subtract this cost from the sale price per head, the gross value
of each of the 22 cows has been reduced from $148.50 to $146.25.
If we had hauled 40 calves which weighed 350 pounds each on this
truck, nnd they brought 30, a pound at the market, what would the cost
per pound have been? The cost per head?

To calculate the cost of hauling cattle in your own truck is a
little more complicated. Therecare a variety of costs involved which
mus be consideredJ. lie hav ,re iou.ly dousaaed depreciation as a
bookkeeping procedure .for spreaAding che c: t of i capital item over the
years of service of the item. This is one of the costs of owning a
truck.
There are 2 major categories (classes) of costs involved, so let's
first list them and then go over each in detail.
I. Fixed Costs
(a) Interest on Investment
(b) Depreciation
(c) Insurance
(d) Taxes
II. Variable (Operating) Costs
(a) Gas, oil and grease
(b) Repairs
(c) Labor
Interest on Investment: This is an opportunity cost and must be
calculated to obtain the Total Cost of owning a truck. The fact that we
call this an opportunity cost relates to the fact that if we did not use
the money to buy a truck, we would have the opportunity to buy something
else with the same money. In other words, when we spend time building
fence we could be fishing or hunting, we are giving up the opportunity to
fish or hunt in order to build fence. That makes building a fence a
pretty expensive item.
If we can buy a truck for $5000 and figure it will be worth $500 at
the end of five years, we can calculate the average annual interest on
investments We first must calculate the average value of the truck just
as we calculated the average values on inventory.
Beginning Value $5000
Ending Value 500 $5500 4 2 $2750
$5500
If we decide that our money could be invested in some other way and return
a 6% interest we can multiply this interest rate times the average value;
$2750 X .06 $165

This $165 is the opportunity cost of owning the truck and is a fixed
cost. It will cost us this much whether we use the truck or not.
Depreciation: As you remember, when we calculated depreciation
before, we subtracted the salvage value (value at end of useful.life)
from the original cost and divided the remainder by the numbers of years
we expected to use the truck. This gave us the average annual deprecia
tion. In the case of this cow truck, the calculations would be as follows:
Original Cost $5000
Salvage Value 500
$4500
$4500 4 5 $900
Insurance: This is described as a risk cost and should be considered
as a real cost whether you carry insurance or not. If you don't carry
insurance you are taking the risk yourself; and if you do carry the insurance,
you are transferring the risk to the insurance company. Buying insurance
is kind of like hiring someone else to break a horse for you. Part of the
pay you give him is for risking his neck instead of yours. For this example,
we will assume an insurance cost of 3% of the average value:
$2750 X .03 $82.50
Taxes: The last fixed cost we will consider is taxes. This item on
a truck would consist mainly of the license tag, which should be in the
neighborhood of $75.
We can now add up the Total Fixed Cost.
Interest on Investment $ 165.00
Depreciation 900.00
Insurance 82.50
Taxes 75.00
Total Fixed Cost $1,222.50
Total Fixed Cost: This is the amount of the cost of owning the
truck whether it is used or not.
Next let's take a look at the Variable (Operating) Costs. The
only way to obtain accurate figures for calculating operating costs is
by keeping accurate records on the operation of the truck. Since we
don't have these on this particular truck, we must use data generated
from experimental work. Dr. Whitney at the Citrus Experiment Station
has published data on the operation of a similar truck which we may use.
His costs are as follows:
Repairs and Maintenance $ .49 per hour
Fuel Costs (gas, grease, and oil) .75
Labor Costs 1.50
Total Operating $2.74
If we assume that under average conditions this truck will be operated
at 35 miles per hour, the operating cost per mile would be:
$2.74 4 35 = $.0782 or 7.8 per mile.
This 7.8 per mile is only operating cost and does not include the fixed
costs which we have already calculated. In order to arrive at a fixed cost
per mile, we must make some assumption (guess) as to how many miles the
truck will be driven in 1 year. If we assume that we will drive the truck
a total of 20,000 miles each year the fixed cost per mile would be cal
culated as follows:
$1,222.50 4 20,000 = $.0611 or 6.1 per mile
If we add the total fixed cost per mile and the operating cost per
mile, we have a total cost of 13.9c per mile.
Fixed cost per mile 6.14 (based on 20,000 miles)
Operating cost per mile 7.8,
Total cost per mile 13.9
Now, let's assume that we can haul 18 head of 350 pound calves on
the truck; the market is still 100 miles from the pens. What will the
S cost per head he?
200 miles
$27.80 4
X 13.9U = $27.80 (Cost of 1
18 = $1.54 per head.
We are now ready to compare the cost of hauling
the market with hiring someone else to do the job if

This does not say that there are not times when a ranch operator
Cannot afford to own his own truck for hauling livestock. For instance,
if you had to have the truck for other purposes, you would only charge
direct operating cost to hauling calves. The picture would then look
as follow:
200 miles
$15.60 4
X 7.8C per mile = $15.60 per round trip

This would be a savings by hauling your own calves of 36; per, head.
Cost of hired hauling $1.23 per bead
Cost of own hauling .87 per head
Savings $ .36 per head
SOURCES OF CREDIT
There are times when everyone needs additional cash. Whether this
cash is needed for purchasing land, battlee equipment, or for taking a
vacation, would probably influence the length of time for which it would
28
be borrowed. The length of time involved in a loan will often influence
the source of the loan. Some institutions are set up to make mostly
shortterm loans, while others will loan money for extended periods of
time. We shall discuss sources of credit with respect to use and to
length of time. We will consider longterm loans first and discuss the
sources of these loans.
There are three major sources of longterm loans, such as would be
needed in purchasing real estate, a herd of cattle, or an extensive
building program. Loans are avaialble from these sources for as long as
30, and even 40 years.
The Federal Land Bank will make only real estate loans; however,
these loans can be for from 5 to 40 years. This institution figures
interest as simple interest, requires an appraisal of the property and'
insurance on improvements. The Land Bank also requires the recipient of
a loan to purchase stock in the association. Land Bank loans are usually
available at low interest rates, when compared to other sources of credit.
The Federal Land Banks were originally financed by the government; however,
all outstanding government loans have been repaid, and the associations
are totally owned by farmers today.
Insurance companies also make longterm real estate loans (from 130
years). They generally charge a slightly higher interest rate than does
the Federal Land Bank; although this is not always the case. The insurance
company requires the same qualifications for loans as does the Land Bank
with the exception of the purchase of stock. One difference in Federal
Lank Bank procedures and some insurance companies is the fact that there
is never a prepayment penalty on a Federal Lank Bank loan. Some insurance
companies have a prepayment penalty clause in their mortgage agreement.
A prepayment penalty simply requires payment of interest for a specified
time even though you don't use their money for the full time. This is a
point which should be definitely considered in selecting a source of
capital. If there is a prepayment penalty and a loan is paid off early,
the result is the raising of the effective interest rate.
The Farmers Home Administration is the third source of longterm
money. F.H.A. operates very similarly to the Federal Land.Bank as far
as qualification of the borrower on real estate loans; however, F.H.A.
loans may run for 140 years and are not necessarily real estate loans.
It is also possible to obtain shortterm operating and improvement loans
through F.H.A. The interest rate is the same for all three types of
loans from F.H.A. and is lower than the other two sources of loans. Of
course, with F.H.A. making three types of loans available, this institution
is active in shortterm and intermediate term loans also. F.H.A. loans
are generally available only to those producers who have no other source
of credit.
There are generally two sources of intermediate term loans besides
F.H.A., and both of these make real estate loans. The two sources are
savings and loan associations and individuals.
Savings and loan associations are most likely to be involved in
real estate mortgage loans, and will make these loans for 5 to 20 years.
They figure interest by the simple or true annual interest method and
require a closing cost. They do not require a purchase of stock and
generally do not have a prepayment penalty. The "closing" costs involved
in a savings and loan association loan may include investigating borrower,
appraising property, commissions, recording mortgage, title examination,
abstracting, lien search, taxes, revenue stamps on real estate deeds, etc.
These costs could add 1 to 1 1/2 percent of the amount of the loan, and
actually increase effective interest rate.
The second source of intermediate credit is individual lenders.
Actually, individuals are operating in several categories of loans.
These loans most likely are made for a period of from 5 to 10 years, and
can be made as operating, improvement or real estate loans. Individuals,
at times, are the cheapest source of capital, Some individuals are
willing to make loans at interest rates which are below rates charged
by other credit sources.
There are several sources of shortterm credit including production
credit associations, retailers and associated finance companies, small
loan companies, credit unions and commercial banks. Commercial banks
will be discussed last, because they are more or less a special case.
Production Credit Associations were originally established by the
Federal Government to make operating capital available to farmers at a
reasonable rate. The Production Credit Associations are farmer owned.
They are still generally the cheapest source of operating or improvement
capital. Their loans are normally made from 1 to 5 years. Like the
Federal Land Bank, borrowers from the P.C.A. are required to purchase
stock in the association. This stock is recoverable when the loan is
paid off, and is usually figured as a percentage of the loan.
Retailers and their associated finance companies make loans normally
for from 1 to 4 years for operating capital, improvements and consumer
goods. The interest charged is higher than P.C.A. on operating and
improvement loans and much higher on consumer goods. A borrower might
pay as much as 36% for a loan to purchase a consumer good (automobile,
television, dishwasher, etc.) from these institutions. "They charge a
closing cost, require insurance and retain a prepayment penalty clause
in their notes in most all cases.
Small loan companies usually make only consumer goods loans for a
period of from 1 to 3 years. They charge up to 36% interest, charge a
closing cost, have a prepayment penalty clause and require property credit
life.
Credit unions make loans available to members for operating, improve
ments and consumer goods. They usually charge a higher interest rate for
operating and improvement loans than do retailers; however, their consumer
goods loans are far cheaper than either retailers or small loan companies.
There is generally no prepayment penalty clause; however, they charge a
closing cost and furnish life insurance. Credit unions make loans normally
for a period of from 1 to 3 years.
The discussion on commercial banks has been left to last, because they
are involved in most phases of lending. They generally charge a registra
tion (closing) fee, require no stock purchase, require insurance in some
cases, but have no prepayment penalty. Commercial banks extend operating
loans up to 1 year and are fairly competitive with P.C.A. on interest rates.
The same competition is true of improvement loans by banks, which are made
for a period of from 1 to 5 years. Real Estate loans are made by commercial
banks for a period of from 1 to 20 years, at an interest rate which in some
cases is competitive with Federal Land Banks and Insurance Companies. This
puts them in the intermediate, or almost longterm financing field. They
also make loans for consumer? goods at interest rates comparable to credit
unions.
Most sources of credit have been covered thus far. Now a point or
two to remember in using credit. It is generally best for an individual
or a firm to establish a "credit home." A "credit home" could be defined
as an institution which is reliable and dependable, where credit is avail
able at competitive interest rates. This institution is known well by
the individual and the individual is wellknown to the institution. In
other words, the individual should generally obtain his credit from the
same institution. This does not preclude shopping for a better credit
deal; however, if credit is established with an institution over a period
of years, this usually results in a less expensive borrowing situation in
the long run.
The most important factor to remember in reference to credit and
borrowing is  BE SURE YOU NEED EXTRA CAPITAL BEFORE BORROWING.
FIGURING LOAN COSTS
Interest is the price of money. There are many ways to calculate
interest. Since the "truth in lending" bill was passed, lenders must
plainly state what simple annual rate of interest they are charging.
But even if we know what the loan will cost in percent, we must often
figure this out in dollars because we may be limited in the amount of
money we have to spend in a year.
For example, if you need $1,000 for a year and the banker will charge
8 percent interest, what is the dollar cost of this loan?
$1,000 X .08 $80.00
Therefore at the end of a year, you would have to repay $1,080.
Suppose a rancher secures a loan of $4,500 from a lender to help
pay annual ranch operating expenses for such items as fertilizer and
labor. The loan was made for a 9 month period, and paid off at the end
of the 9 months. The lender charged 7 percent interest on the money
loaned. Calculate the cost of the loan to the rancher.
Determine the annual cost of the loan by multiplying the total
amount of the loan, or $4,500, by the annual interest of 7 percent.
$4,500 X .07 $315.00
The annual cost of the loan would be $315. Determine the cost of
the loan for one month by dividing the annual cost by 12.
$315.00 12 $26.25
The cost of the loan for one month would be $26.25. Determine the
Cost of the loan for 9 months by multiplying the cost for one month by 9.
$26.25 X 9 months $236.25
The cost of the loan of $4,01)0 carrying an annual rate of interest
of 7 percent for a period of 9 months was $236.25.
You might know what a loan had cost in dollars and want to know the
simple interest rate (R).

Example: A $100 loan for one year with a Dollar Cost of $8.00.

If you buy anything on the installment plan, or on a credit card,
you must usually pay a higher rate of interest than "bank rates of
interest". For example, many major oil companies charge 1.5% interest
on the unpaid balance per month. This is 18% on the basis of simple
annual interest (12 x 1.5 18). Remember that any agency extending
credit must tell you what the interest will be on the basis of simple
annual interest.
There is a publication available which shows a general formula
for figuring interest; gives a table of compound interest (used to
calculate long term loans on real estate) and many other useful aids
for a manager. It is; "Farmers' Handbook of Financial Calculations and
Physical Measurements, Agriculture Handbook No. 230". For sale (35c)

"charge it" at a rate of 2% per month.
A. What is the dollar cost of this loan if we repay the $100
in 3 months?
B. What is the annual rate of interest at 2% per month?
3. Suppose you borrowed $6,500 for a year and repaid $6,558.50.
