See whether it pays to keep your own machine or hire the service per hectare, and the area from which owning becomes cheaper.
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.
Cost per hectare of each option, with the area entered; the highlighted bar is the lowest cost.
Annual cost of both options for 100 to 2,000 ha per year; the crossing of the lines is the break-even area.
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 hectare of both options for different areas per year, with the fixed cost and service price entered.
The calculation done in steps, with the values you entered.
Improvement cash flow: investment in year 0 and annual savings adjusted by the entered increase, discounted at the minimum attractive rate of return (TMA).
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.
You can enter the annual fixed cost or, if you prefer, the machine price: in that case the calculator computes depreciation, interest and insurance, and the card Project return shows the payback and NPV of the purchase.
Enter the machine's annual fixed cost, the variable cost per hectare, the price of the outsourced service per hectare, and the area worked per year. The calculator shows the cost per hectare of each option and the breakeven area.
Fixed cost of R$ 60,000 per year, variable cost of R$ 95 per hectare, outsourced service at R$ 180 per hectare and 800 ha per year.
Owned = 60,000 + 95 × 800 = R$ 136,000 per year, or R$ 170.00/ha. Outsourced = 180 × 800 = R$ 144,000, or R$ 180.00/ha. Difference of R$ 8,000 in favor of doing it in-house. Break-even area = 60,000 ÷ (180 − 95) = 706 ha per year.
Depreciation, interest on capital, insurance, shelter, and the fixed part of maintenance. It is paid even if the machine works little.
Because it shows how many hectares per year are needed for owning the machine to pay off. Below that, outsourced service tends to be cheaper.
Yes. During the harvest or planting window, the contractor's availability can delay the operation. This cost is not included in the calculation; assess it separately.
Yes. Add the fixed part of the hourly cost multiplied by the hours per year, and use the variable part per hectare.
