Methodology follows ISU Extension AgDM File C2-23. The 0.30 and 0.25 factors convert hay value to standing-grazed forage value (forage is worth less when grazed vs harvested). AUM rent = hay price × quality factor; total assumes a 6-month grazing season. Per-pound-of-gain rent = weight gained × rate × head. Compare methods on a per-acre annual basis below.
The Oaken pasture rent calculator helps a landowner and livestock operator or hay producer agree on a fair per-acre cash rent for grazing and forage land. Instead of a fixed guess, a data-driven approach weighs forage type, pasture quality, carrying capacity, and livestock so that rent reflects actual forage value. Enter your forage type, pasture quality, grazing livestock, and stocker cattle, and the calculator computes rent six different ways and converts each to a per-acre annual basis for easy comparison. Defaults match the ISU Example.
This hay land rent estimator follows the Iowa State University Extension Ag Decision Maker File C2-23, Pasture and Hay Land Cash Rent Worksheet by Ann Johanns and William Edwards. The worksheet is a standard reference across the Corn Belt for setting pasture and hay land cash rent.
Rent is estimated six ways — per-ton forage value, carrying capacity in AUMs, per-head-per-month, per-pound-of-gain for stocker cattle, per-AUM rental rate, and a hay-equivalent approach. Each method produces a per-acre annual rent so you can compare approaches and negotiate a defensible figure.
An AUM is the forage a mature 1,000-pound cow consumes in one month (about 26 pounds of dry matter per day). The grazing lease calculator multiplies a pasture's carrying capacity in AUMs per acre by a rental rate per AUM to estimate rent; different pasture types carry different typical AUM values.
Because the six methods use different units (tons, AUMs, head, pounds of gain), the calculator normalizes every result to a per-acre annual rent. This gives landlords and tenants a single, comparable number for each method and a clear range for negotiation.
Pasture and hay land cash rent is the per-acre payment a livestock operator or hay producer pays a landowner to graze or harvest forage from a tract of land for a season. It is negotiated based on forage productivity, pasture quality, carrying capacity, and local market conditions, and is distinct from cropland cash rent.
The Iowa State University Extension Ag Decision Maker File C2-23, Pasture and Hay Land Cash Rent Worksheet, by Ann Johanns and William Edwards, estimates rent several ways and converts each to a per-acre annual figure for direct comparison. This pasture rent calculator follows that worksheet's methodology and default example.
An AUM (Animal Unit Month) is the amount of forage a mature 1,000-pound cow consumes in one month, roughly 26 pounds of dry matter per day. The C2-23 worksheet uses carrying capacity in AUMs per acre, multiplied by a rental rate per AUM, to estimate pasture rent. Different pasture types have different typical AUM-per-acre values.
This calculator estimates rent six ways: per-ton forage value, carrying capacity (AUMs), per-head-per-month, per-pound-of-gain for stocker cattle, per-AUM rental rate, and a hay-equivalent approach. Each method produces a per-acre annual rent so landlords and tenants can compare approaches side by side.
The estimator is an educational and negotiation tool that replicates the published ISU AgDM C2-23 methodology. It uses the inputs you provide and published default forage and AUM values, and does not pull live market data. Always verify figures with current USDA NASS data and your own forage and livestock records before signing a lease.
Oaken tracks grazing agreements, AUM settlements, and forage valuations in one system of record.
