Compare the gross margin per hectare of two crops: revenue minus variable cost, and how much the difference is worth on your area.
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.
Revenue minus variable cost per hectare; the highlighted bar is the one that earns the most.
Margin per hectare of the two crops if the grain price varies from −30% to +30%.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Margin per hectare of each crop when the grain price varies from −20% to +20%.
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.
For each crop, enter the expected yield in bags per hectare, the price per bag and the variable cost per hectare. The calculator shows each crop's margin and the difference for the area you entered.
Crop A: 60 bags/ha at R$ 120, variable cost of R$ 2,400/ha. Crop B: 150 bags/ha at R$ 50, variable cost of R$ 3,000/ha. Area of 100 ha.
Margin A = 60 × 120 − 2,400 = R$ 4,800/ha. Margin B = 150 × 50 − 3,000 = R$ 4,500/ha. The difference of R$ 300/ha is worth R$ 30,000 on the area, in favor of crop A.
Because gross margin shows what each crop leaves to pay fixed costs and profit. Profit depends on cost allocation, which varies from farm to farm.
Because variable cost changes a lot from one crop to another. A crop with high revenue but high cost can have a smaller margin.
Compare the two crops with realistic prices and yields for your area. Rotation also brings benefits that do not show up in this calculation, such as disease and weed control.
The chart shows the effect of a change in grain price. If the two lines cross, the crop that earns more changes with the price.
Important notice: the Agrocalcs tools make estimates and preliminary sizing based on the data entered and on published engineering methods. They do not replace a design, a calculation report or a report signed by a qualified professional (CREA/ART), nor verification against the applicable technical standards and legislation, such as the Regulatory Standards of the Ministry of Labor.
