Dairy Profit Calculator & Does the Milk Pay?
Costs out cow dairies
See whether your milk pays — turn herd size, yield, milk price and costs into daily, monthly and per-lactation profit, the true cost per litre and your break-even milk price.
Other cost = labour, vet, breeding, electricity, depreciation etc. per animal per day.
Your dairy makes about ₹2,100 a day (₹63,000/month) — each litre costs ₹23 to produce and sells for ₹40, a margin of ₹18/L.
Next: the biggest lever is feed cost per litre — improving yield per animal or cutting feed waste raises margin fastest.
A planning model from your inputs — it doesn't include herd replacement, calf value, manure income or capital. Adjust costs to your farm.

Know your cost per litre
Dairy margins are thin and made on volume, so the single most important number is your cost per litre — total daily cost divided by daily milk. Once you know it, everything else follows: compare it to your milk price for the margin per litre, read off the break-even price you can never sell below, and scale the daily margin to what the dairy really earns in a month and across a lactation. Feed is usually 60–70% of that cost, which is why it dominates profitability.
The tool lays this out so you can test changes before making them: a higher yield per animal spreads fixed costs over more litres, cheaper or home-grown fodder cuts cost per litre directly, and a better milk price lifts the whole margin. Treat the result as a planning model — it counts milk against running costs and excludes calf, manure and capital items, which you should weigh separately for whole-farm returns.

Frequently Asked Questions
How do I calculate dairy farm profit?+
Multiply herd size by milk per animal for daily milk, then by milk price for revenue. Add up feed and other costs per animal and subtract from revenue for the daily margin. This tool does it all and scales the margin to monthly and per-lactation figures, plus per-litre economics.
How do I work out cost per litre of milk?+
Divide total daily cost (feed + other costs across the herd) by total daily milk. If 10 cows cost ₹2,500 a day and give 120 litres, that's about ₹20.8 per litre. Comparing this to your milk price shows your true margin per litre.
What is the break-even milk price?+
It's the price per litre at which revenue exactly covers cost — equal to your cost per litre. Sell above it and you profit; below it and you lose money on every litre. The tool shows this figure so you know the floor price you can accept.
What costs should I include?+
Feed (green and dry fodder plus concentrate) is the largest, typically 60–70% of cost. 'Other costs' should capture labour, veterinary and medicine, breeding, electricity and water, bedding, and a share of depreciation on animals and equipment, all expressed per animal per day.
Why is feed cost so important in dairy?+
Feed is the biggest and most controllable cost, so cost per litre rises or falls mainly with feed price and feed efficiency. Improving yield per animal, reducing feed waste and balancing rations are usually the fastest ways to widen the margin — size rations with our Livestock Feed Calculator.
What is a good profit margin in dairy?+
It varies widely by region, scale and milk price, but a healthy small dairy often aims for a margin of a few rupees (or cents) per litre after all costs. Because margins per litre are thin, total profit depends heavily on yield per animal and herd size.
How does lactation length affect profit?+
Profit per lactation is the daily margin multiplied by the days an animal is in milk (often around 305). Longer productive lactations and shorter dry/calving-interval gaps spread fixed costs over more litres and raise annual profit.
Does this include calf or manure income?+
No — to stay clear and conservative it counts only milk revenue against feed and other running costs. Calf value, manure sales and culling income are real but variable; add them separately when assessing whole-farm returns.
How can I improve my dairy margin?+
Lift milk yield per animal through better nutrition, breeding and comfort; cut feed cost per litre by reducing waste and using home-grown fodder; keep animals healthy to avoid vet costs and lost days; and negotiate or add value to your milk price (e.g. direct sales).
Is this a substitute for proper farm accounts?+
No — it's a fast planning model to test scenarios and understand your cost per litre. For loans, grants or major decisions, keep detailed records and consult a dairy advisor or accountant.
