Cow Feed Cost
Free Cow Feed Cost calculator with clear step-by-step results.
About Cow Feed Cost
Cattle rations are costed on a dry matter basis because forage moisture varies enormously. Splitting intake between forage and concentrate at their respective prices gives cost per head per day - the single most useful figure for comparing rations - and scaling by herd size and days gives the feed bill.
Formulas
Cost per head per day
Cost = (forage kg DM x forage price + concentrate kg x concentrate price) / 1000
Period cost
Period = cost per head per day x head count x days
Worked example
With the default values below, Cow Feed Cost returns Feed cost for the period of $5,016.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation or tax into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
What is typical dry matter intake?
Roughly 3-3.5% of body weight: about 20-24 kg DM for a lactating dairy cow, 10-12 kg for a dry cow and 8-10 kg for a growing heifer.
Why cost forage at all if I grow it?
Home-grown forage still consumes land, fertiliser, machinery and storage. Costing it at market value is what makes ration comparisons and stocking decisions meaningful.
