Land Rent Calculator

Estimate fair cash rent for cropland based on soil productivity rating (CSR), commodity price, expected yield, and property taxes.

About this calculator

Estimated Fair Cash Rent is Gross Revenue (Expected Yield times Commodity Price) multiplied by an adjusted rent ratio that starts from a 33% baseline and scales proportionally with CSR / Productivity Rating relative to a reference CSR of 85 -- so raising CSR, Commodity Price, or Expected Yield each raises Estimated Fair Cash Rent, with no term that ever works against another. Rent as % of Revenue reduces algebraically to just the adjusted rent ratio itself: Commodity Price and Expected Yield both cancel out of the fraction because they scale the numerator and denominator by the same amount, so Rent as % of Revenue moves only with CSR / Productivity Rating and stays completely flat -- inert -- against Commodity Price, Expected Yield, Property Taxes, and Land Value, even though the dollar-amount rent figure itself responds to all of those. Net Rent (after taxes) subtracts Property Taxes directly from Estimated Fair Cash Rent, so raising taxes always lowers net rent dollar-for-dollar.

Landlord ROI divides Net Rent by Land Value, so at a fixed net rent, a higher Land Value produces a lower percentage return -- the same rent dollars represent a smaller return on a more expensive parcel. Estimated Tenant Profit subtracts both Estimated Fair Cash Rent and a fixed $450/acre production-cost assumption from Gross Revenue; because a higher CSR raises the rent charged without raising Gross Revenue itself (CSR doesn't enter the revenue calculation at all), raising CSR actually lowers Estimated Tenant Profit even though it represents better land.

How to Use This Calculator
  1. Enter the field's CSR (Corn Suitability Rating) or equivalent productivity index, expected crop yield per acre, and projected commodity price.
  2. Enter property taxes per acre and the land's current market value per acre.
  3. Review the estimated fair cash rent per acre, scaled to the field's CSR relative to a baseline of 85.
  4. Check the net rent to the landlord after taxes and the resulting landlord ROI based on land value.
  5. Compare rent as a percentage of gross revenue and the estimated tenant profit to gauge fairness for both sides.

What each input means

CSR / Productivity Rating
Corn Suitability Rating or equivalent productivity index (0-100). Higher = better soil. Iowa avg: ~75.
Commodity Price (Corn)
Current or expected corn price per bushel. Used as the base commodity for rent calculations.
Expected Yield
Trend-line yield for the field in bushels per acre.
Property Taxes
Annual property taxes per acre paid by the landowner.
Land Value
Current market value of the land per acre, used to calculate return on investment.

Frequently Asked Questions

My landlord wants a fixed percentage of revenue regardless of price swings -- does that match this calculator's model?

Not quite -- Rent as % of Revenue in this model tracks only CSR / Productivity Rating, not commodity price, so what your landlord is describing sounds like a flex-rent lease tied to market price swings, which is a genuinely different contract structure than the fixed-ratio, soil-quality-based fair cash rent this calculator estimates.

Why does a more valuable parcel show a lower Landlord ROI at the same rent?

Landlord ROI is Net Rent divided by Land Value, and Net Rent doesn't depend on Land Value at all in this calculation. So when Land Value rises while the rent dollars stay fixed, the same numerator is being divided by a larger denominator, which mechanically produces a lower percentage return.

As a tenant, should I push back on a higher-CSR rent premium if my own yield estimate already reflects that better soil?

This model raises the rent ratio with CSR but never adds that same CSR advantage into Gross Revenue, which comes only from Expected Yield times Commodity Price, so if the yield you entered already reflects the field's true productivity, the CSR-driven rent premium is being charged on top of a yield that may already account for the better soil, worth raising with your landlord.

Who typically pays the property taxes in a cash-rent lease -- is that already folded into the tenant's payment?

In this calculator's structure, the landlord bears the tax bill: Net Rent to Landlord is Fair Cash Rent minus Property Taxes, taken out of what the landlord collects rather than added onto the tenant's payment, which mirrors how most real cash-rent leases work -- the landowner pays property taxes separately, and the tenant's rent check doesn't fold them in.
