Farm Land Value Calculator
Estimate what farmland is worth from its rent-earning power and soil quality. The income-capitalization method and a soil-productivity adjustment give you a defensible value per acre and hectare.

How to Use This Calculator
Enter the acreage, a soil productivity index (0-100, use your county's CSR2 or similar), an improvement factor (1.0 average; 1.15-1.25 irrigated/drained), the typical annual rent per acre, and a capitalization rate (typically 3-5%). Click Calculate.

Applicability: Useful for farm financial planning in North American and European agricultural operations.
How the Calculation Works
Income Approach: Value = Annual Rent ÷ Cap Rate. Soil factor = 0.5 + (CSR/100)×1.0, spanning 0.5 (poor) to 1.5 (top). Adjusted value = income value × soil factor × improvement factor. For 160 acres, $220/acre rent, 4% cap: income value = $35,200 ÷ 0.04 = $880,000 = $5,500/acre. With soil 75 → factor 1.25, improvement 1.0: soil-adjusted = $1.1M. Value/ha = $5,500×2.471. Common mistakes: using cap rates too low (3% inflates value), ignoring location, and treating rent as capital gain.

Frequently Asked Questions
What capitalization rate should I use?
Farmland cap rates are typically 3-5% in the US, reflecting low risk and steady demand. Lower rates imply higher value; use a rate comparable to recent land sales in your county, and remember that rents and rates move inversely.
What is CSR2 and how do I find my soil index?
CSR2 (Comprehensive Soil Rating, 2.0) is a soil productivity index used in Iowa and neighboring states, 0-100. Most state extension services publish soil survey maps online; NRCS Web Soil Survey also maps soil productivity for free.
How much does irrigation add to land value?
Irrigated land often sells at a large premium over dryland because yield and income are far more stable. The improvement factor of 1.15-1.3 captures this. The premium depends on water rights reliability and pumping costs.
Is the income approach the same as market value?
They should bracket each other but rarely match exactly. Income approach reflects what the land earns; market value reflects what buyers recently paid. If income value is far below recent sales, buyers may be speculating or valuing non-farm uses (development, hunting).
Does this replace a professional appraisal?
No. Lending and legal transactions require a certified appraisal. This tool is for quick negotiation anchors and sensitivity analysis — adjust the soil index, rent and cap rate to see how value moves.
