See the cost of each liter of milk produced and the margin at the price you receive.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
How much each liter costs at production of 15 to 35 L per cow; the highlighted bar is yours.
Margin in the month at different liter prices; the line crosses zero at the breakeven point.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Cost per litre and margin for the month at yields of 15 to 35 L per cow per day, with the milk price entered.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Enter the number of lactating cows, the average yield per cow, the price per liter, and the monthly costs: feed, labor, health and breeding, and other costs. The calculator shows the cost per liter and the margin.
50 cows, 25 L per day, milk at R$ 2.40 and costs of R$ 60,000 (feed), R$ 12,000 (labour), R$ 5,000 (animal health) and R$ 8,000 (other).
Liters = 50 × 25 × 30 = 37,500 L. Total cost = R$ 85,000. Cost per liter = 85,000 ÷ 37,500 = R$ 2.27. Revenue = 37,500 × 2.40 = R$ 90,000. Margin = R$ 5,000 per month.
Because much of the cost is fixed each month: labor, health and facilities do not change with production. With more liters per cow, these costs are spread out.
Generally yes. That is why the diet deserves attention: see the calculator for diet cost per animal per day.
Yes, and it is the most reliable. Use the actual costs from a closed month, not estimates.
Not directly. It shows the margin of the current operation. A decision to expand also depends on investment, credit, and the capacity of the area.
