Normally, lenders allow contract producers with a dependable, modern production system to put up only 15-20% of the new cost of the building as inital equity. This is because the cash flow from the unit is dependable and uniform. Because such a small amount of initial equity is required, returns on equity (ROE), the primary measure of financial outcome tend to be very high for the grower.
As mentioned previously, the payment is calculated to reimburse the grower for all costs including principal and interest on the note at a relatively small initial equity. Returns on equity (ROE) can run in the 40-70% range depending on the length of the contract and the terms of the note. Usually, this return does not calculate or factor in the cost reduction in fertilizer which accrues to those who can use the manure nutrients to offset fertilzer needs on a cash crop such as corn. When these returns are included, net of application cost, the total returns to a contract wean to finish or finishing building become some of the best that can be achieved in agriculture.
