    How to use

    Enter the combined lease in bags per hectare, the expected yield, the bag price, the production cost per hectare, and the leased area. The calculator shows the fraction of production paid and the surplus.

    Worked example

    Lease of 15 bags/ha, yield of 60 bags/ha, bag at R$ 120, production cost of R$ 4,200/ha and area of 200 ha.

    Share = 15 ÷ 60 = 25%. Amount paid = 15 × 120 = R$ 1,800/ha. Revenue = 60 × 120 = R$ 7,200/ha. Surplus = 7,200 − 4,200 − 1,800 = R$ 1,200/ha, or R$ 240,000 on the area.

    Precautions

    • Compare the calculated yield with the field's actual history, not only with the regional average.
    • See also the gross margin between crops to decide what to plant on the leased area.

    Method, assumptions, and references

    Equations used

    Share of production (%) = Lease (bags/ha) ÷ Yield (bags/ha) × 100
    Net return (R$/ha) = Yield × Price − Production cost − Lease (bags/ha) × Price

    Assumptions and limits

    • Bag price and yield held the same for the period; no crop variation.
    • Production cost includes all crop items, including depreciation and interest on own capital, if they are part of the analysis.
    • Does not consider taxes, insurance, or advance payment.

    Standards and technical documents

    • Price and yield data for your region (CONAB and Cepea, published series). Also check the lease contract.

    Frequently asked questions

    Why pay in bags?

    Because income follows yield and grain price. In years of crop failure, the amount paid falls along with production, which splits the risk between owner and tenant.

    What share of production is reasonable?

    There is no fixed number. It depends on the regional price, the quality of the land, and the production cost. Compare with the local average and with your cost.

    Does the calculation consider the production cost?

    Yes, on the leftover line. If the cost is left out, the leftover value is overestimated.

    Does this calculation replace the contract?

    No. It helps compare proposals. The contract should set out the term, adjustment, payment method, and responsibilities.
