Cattle Feed Cost Calculator

Enter your head count, pounds of feed per head per day, cost per pound, and the number of days. Get the total feed cost, the cost per head, and your daily feed bill — the numbers that actually tell you whether the cattle are paying their way.

How to figure your cattle feed cost

The math is simple, but most operations never run it: head × lbs/head/day × $/lb × days gives your total feed cost for the period. Divide by head count and you have cost per head — the number that actually matters, because it's what you compare against the price you'll get at sale. Divide by days and you have your daily feed bill, which is the figure that makes people rethink an overstocked winter.

A mature beef cow eats roughly 2 to 2.5% of her body weight in dry matter per day — about 24–30 lbs for a 1,200-lb cow on hay, more on a finishing ration with grain. The two inputs people get wrong are pounds per head (weigh a few feedings instead of guessing) and cost per pound (use your delivered cost — total paid divided by pounds received — not the catalog price). And don't forget waste: fed on the ground, 30%+ of hay can be trampled and fouled, which a feeder and proper storage cut to single digits. That waste is real money that never shows up unless you account for it.

From a one-off estimate to your real cost per head

This calculator gives you a snapshot. The problem is that a snapshot goes stale the moment feed prices move or you change the ration, and it never ties back to what the cattle actually sold for. FarmsFlo logs your feed purchases and inventory and ties them to your herd, so you get real feed cost per head over time instead of a back-of-the-envelope guess each season. It rolls straight into your farm P&L alongside sales, so you can see the actual margin on your cattle — not a hopeful estimate. Inventory tracking is part of Pro ($29/mo), and the full farm financials and P&L are part of Complete ($79/mo), both with a 14-day free trial; the Free tier covers basic records to start.

Frequently Asked Questions

How do you calculate cattle feed cost?
Multiply head count by pounds of feed per head per day, then by your cost per pound, then by the number of days. That gives total feed cost for the period. Divide by head count to get cost per head, and divide by days to get your daily feed bill. This calculator does all four for you from those inputs.
How much feed does a cow eat per day?
A mature beef cow eats roughly 2 to 2.5% of her body weight in dry matter daily. For a 1,200-lb cow that is about 24 to 30 lbs of dry matter — more on a finishing ration with grain, less on maintenance hay or pasture. Growing and finishing cattle on feed often run 2.5 to 3% of body weight. Use the figure that matches your ration and weigh a few feedings to dial it in.
What is a typical cost per pound of cattle feed?
It varies widely by feed type and region. Mixed hay often lands somewhere around $0.05 to $0.12 per pound depending on quality and the year, while grain and complete finishing rations run higher. The honest answer is to use your own delivered cost per pound — what you actually paid, divided by the pounds you actually received — because that is the only number that reflects your operation.
How do I lower my cattle feed cost per head?
The biggest levers are reducing waste (feeders and proper bale storage can cut hay waste from 30%+ down to single digits), buying feed in bulk and in season, extending grazing where you can, and matching the ration to the animal so you are not overfeeding maintenance cows a finishing diet. You cannot manage any of that without knowing your real cost per head first, which is what this calculator and good records give you.
Why does cost per head matter more than total feed cost?
Total feed cost tells you what you spent; cost per head tells you whether you spent it well. It is the number you compare against the price you will get at sale, against last season, and against a benchmark. Two operations can have the same total bill while one is twice as efficient per animal — and only cost per head reveals that.
Can FarmsFlo track feed cost automatically?
Yes. FarmsFlo logs feed purchases and inventory and ties them to your herd, so you get real feed cost per head over time instead of a one-off estimate. It rolls into your farm P&L alongside sales, so you can see the actual margin on your cattle rather than guessing from a calculator each season.
