Calculate net profit per animal, cost of gain per kg, total operation profit, and profit margin percentage for your livestock enterprise.
This calculator breaks down all costs of production — purchase, feed, veterinary, overhead — against sale price to determine net profit per head. It also computes cost of gain ($/kg) and overall profit margin. Essential for evaluating livestock enterprise profitability.
A 50-head cattle finishing operation buys feeders at $500, spends $250 on feed, $35 vet, $40 overhead, sells at $950. Net = $950 − $825 = $125/head. Total profit = 50 × $125 = $6,250. Cost of gain = $250 ÷ 200 kg = $1.25/kg. At 13.2% margin, this is decent — but feed cost reduction or better sale price could add $3,000+.

The Profit per Head Calculator helps producers evaluate enterprise economics. Understanding cost of gain and margin percentage guides decisions on: buy vs raise, when to sell, how much to invest in quality, and whether to expand. NRC nutrient requirements drive feed cost optimization.
Total cost/head = purchase + feed + vet + overhead. Net profit/head = sale price − total cost. Cost of gain = feed cost ÷ weight gain (kg). Total profit = net/head × head count. Margin = net ÷ sale × 100. Healthy margins: 10-20% for finishing cattle, 5-15% for dairy.
Purchase $500 + feed $250 + vet $35 + overhead $40 = $825 cost. Sale $950. Net = $125/head. Total (50 head) = $6,250. Cost of gain = $250 ÷ 200 kg = $1.25/kg. Margin = 125/950 = 13.2%. Break-even sale price = $825/head.
Common mistakes: forgetting to include overhead costs, not accounting for death loss, using current sale price but historic purchase cost. Tip: calculate per head AND per kg of gain — the latter reveals feed efficiency. Compare your cost of gain against local benchmarks. NRC-based rations can reduce feed cost while maintaining gain.
Beef finishing: 10-20% margin ($100-200/head). Dairy: $15-30/cow/month net profit. Sheep: $20-50/head. Pigs: $15-40/head. Margins vary with commodity cycles. Feed typically represents 60-75% of total cost. NRC-aligned rations optimize feed cost vs gain. Track monthly margins, not just annual.
Cost of gain = total feed cost ÷ total weight gain. For feeders: if you spent $250/head on feed and gained 200 kg, cost = $1.25/kg. Target cost of gain: $1.00-1.50/kg for feedlot cattle. Higher than $1.80/kg indicates inefficient feeding or poor forage. NRC nutrient requirements help formulate least-cost rations that minimize cost of gain.
Feed represents 60-75% of total variable cost. Then: overhead (labor, facilities, insurance) 10-15%, veterinary/health 5-10%, purchase cost (for stocker/finishing) varies. For cow-calf operations, feed is 50-60% of total cost. Reducing feed cost through better pasture, ration formulation, and waste reduction has the largest profit impact.
Consider: (1) Price cycles — sell when market is high, (2) Cost of gain vs sale price per kg — if cost of gain exceeds value of added weight, sell now, (3) Market outlook — futures and local demand, (4) Feed availability — if feed costs will rise, sell before. Use this calculator with different sale prices to find your break-even and profit scenarios.
Levers: (1) Reduce feed cost — test rations against NRC, improve pasture, reduce waste, (2) Improve gain — health program, genetics, proper nutrition, (3) Increase sale price — quality grading, direct marketing, value-added, (4) Reduce overhead — efficient facilities, reduce labor, (5) Lower death loss — vaccination, biosecurity. Even $10/head improvement on 100 head = $1,000 profit.
