Cost Per Pound of Gain Calculator
Work out cost of gain and breakeven sale price for backgrounded or fed cattle from your own feed, yardage and purchase numbers.
Your numbers
350 lb of gain over 120 days (2.92 lb/day ADG)
$1.208 per lb of gain
- Total cost per head
- $1,440
- Breakeven sale price
- $160.02/cwt
- Total feed cost
- $281
- You purchased this animal for $1,018 at $185.00/cwt and spent $423 more getting it to 900 lb.
- At $1.208/lb this cost of gain is on the high side for most backgrounding or finishing programs — check feed price and intake first.
- This is a planning estimate. Actual closeout numbers depend on your real feed bunk records, scale weights and any treatment cost incurred.
Show the math
- Total gain and ADG900 − 550 = 350 lb ÷ 120 days = 2.92 lb/day
- Feed cost18.0 lb DM/day × $260/ton ÷ 2,000 × 120 days = $281
- Yardage$0.45/day × 120 days = $54
- Interest on average investment$1,202 × 8.0% × (120/365) = $32
- Death loss spread across the pen1.50% × $1,419 = $21
- Cost of gain($281 + $54 + $35 + $32 + $21) ÷ 350 lb = $1.208/lb
- Breakeven sale price($1,018 purchase + $423 feeding cost) ÷ 900 lb × 100 = $160.02/cwt

How to calculate cost per pound of gain
Cost of gain is the number that tells you whether adding pounds to an animal is making or losing money, independent of what you paid for the animal in the first place. It bundles every dollar spent putting on weight — feed, yardage, health, financing and death loss — and divides it by the pounds actually added.
Total gain = out-weight − in-weight
ADG = total gain ÷ days on feed
Feed cost = (lb DM/day ÷ 2,000) × $/ton DM × days
Cost of gain = (feed + yardage + vet + interest + death loss) ÷ total gain
Breakeven $/cwt = (purchase value + feeding cost) ÷ out-weight × 100
Worked example
A 550 lb steer bought at $185/cwt ($1,017.50) goes 120 days to 900 lb, gaining 350 lb at 2.92 lb/day. Feed runs 18 lb DM/day at $260/ton ($702 total), yardage $0.45/day ($54), vet and processing $35, interest on the average investment about $37, and 1.5% death loss adds roughly $19. Total feeding cost of $847 divided by 350 lb of gain is $2.42 per pound — high because this example uses a light in-weight and a full finishing ration; check your own intake and feed price against the reference grid below.
Common mistakes
- Leaving out yardage or interest. Both are real cash or opportunity costs and both scale with days on feed, so skipping them understates cost of gain the most on long-fed cattle.
- Pricing feed as fed instead of on a dry matter basis. A wet or high-moisture ration priced as fed will understate the true dry matter cost driving the ration.
- Confusing cost of gain with breakeven price. Cost of gain ignores the purchase price; breakeven price is what you need at the scale to cover everything, purchase included.
- Using a flat feed:gain ratio at every rate of gain. Feed efficiency changes with ADG, frame size and days on feed — a single ratio is a starting estimate, not a closeout number.
Cost of gain by average daily gain and feed price
Approximate cost of gain in $/lb across a range of ADG and feed price levels, using a simplified 6.5:1 feed-to-gain ratio and $0.15/lb for yardage, health and financing. Use it as a sanity check against the calculator above, not a substitute for your own closeout data.
| ADG (lb/day) | $200/ton DM | $250/ton DM | $300/ton DM | $350/ton DM |
|---|---|---|---|---|
| 1.5 | $0.80 | $0.96 | $1.13 | $1.29 |
| 2.0 | $0.80 | $0.96 | $1.13 | $1.29 |

Questions ranchers ask
How do you calculate cost per pound of gain on cattle?
Add feed cost, yardage, vet and processing cost, interest, and death loss cost into a total cost of gain, then divide that total by the pounds of gain the animal put on over the feeding period. A steer that costs $310 to put on 350 lb of gain has a cost of gain of $0.886 per pound.
What is a good cost of gain for feeder cattle right now?
It moves with corn and DDG prices, but backgrounding programs on grass and byproduct feeds commonly run $0.65 to $0.95 per pound, while high-concentrate finishing rations run $0.85 to $1.20 per pound. Compare your number to current extension feedlot cost-of-gain surveys for your region rather than a fixed target.
How is breakeven sale price different from cost of gain?
Cost of gain only prices the weight you added. Breakeven price also folds in what you paid for the animal, so it answers 'what do I need to sell this animal for to not lose money,' expressed in dollars per hundredweight on the out-weight.
Why does interest matter in a cost of gain calculation?
Cattle and the feed under them are financed capital. An annual interest rate applied to the average dollar value invested over the days on feed is a real cost even if you are using your own equity, because that money had an opportunity cost elsewhere.
How much should I add for death loss?
Multiply your expected death loss percentage by the purchase and feeding investment per head, then spread that cost across the surviving pen. A 1.5% death loss on a $1,400 investment adds about $21 per head in the calculator, distributed as extra cost of gain.
Does yardage include feed cost?
No. Yardage is the per-head, per-day charge for pen space, bunk space, labor, equipment, manure handling and overhead — feed is priced and entered separately as $/ton dry matter and intake.
How do ADG and days on feed relate in this calculator?
Total gain equals ADG times days on feed, so the two must agree with your in-weight and out-weight. Enter days on feed and let the calculator derive ADG from your weights, or adjust days if you already know a trusted ADG figure from past closeouts.
Why is my calculated cost of gain higher than what I read in an extension report?
Published feedlot cost-of-gain figures are pen averages built on large-volume feed purchases, low yardage, and tight death loss. Smaller operations, higher feed cost, higher death loss, or slower gaining cattle will all push an individual pen's true cost of gain above the published average.
Know your breakeven before you buy
Cost of gain only pencils out if the purchase price makes sense to begin with. Agrilot's verified auction listings carry documented weights and health records so you can run this calculator against real numbers before you bid, not after the truck leaves the yard.
