Farm Mortgage Calculator
Farm loans do not behave like suburban mortgages: the payments may be quarterly or annual to match harvest income, the property tax covers land plus buildings, and lenders judge you on farm cash flow, not just salary. This calculator amortizes the loan on your payment schedule, adds PITI, and runs the two affordability tests that matter: debt-to-income and the debt-service coverage ratio.

Quick Answer
Borrow $400,000 at 6% for 20 years with monthly payments and the payment is $2,865.72 per month, with $287,773.82 of total interest over the life of the loan. Add $6,000 annual property tax and $2,400 annual insurance and PITI is $3,565.72 per month. With $10,000 monthly income and $1,000 of other debts, the debt-to-income ratio is 45.66%. Farm income of $200,000 against $150,000 of expenses leaves $50,000 of net farm income; annual debt service is $34,388.69, so the DSCR is 1.45, comfortably above the 1.20 lender comfort zone.
Key takeaways
- The payment formula is ordinary amortization. What is farm-specific is the schedule, the tax and insurance base, and the DSCR test.
- PITI and DTI are always monthly equivalents here, even on quarterly or annual schedules, so the ratios stay comparable.
- DSCR carries more weight than DTI on a farm file: the farm itself must cover the loan.
- Check FSA farm ownership programs before assuming a 20% down payment.

How a farm mortgage payment is built
The payment itself is standard amortization: the loan amount, the periodic interest rate, and the number of payments determine each installment. What makes farm loans different is everything around that formula.
Terms typically run 15 to 30 years, rates sit slightly above residential mortgages, and lenders commonly require a larger down payment than residential mortgages because farmland appraisals are harder to pin down than suburban comps. Payment frequency is the farm-specific twist. A dairy with monthly milk checks pays monthly; a grain operation paid at harvest may pay quarterly or annually. This calculator amortizes on all three schedules, so the payment you see matches the income that funds it. If you are comparing the monthly burden against a house payment, run the mortgage payment calculator for the residential side-by-side.
One honest detail about this tool: PITI and the debt-to-income ratio are monthly equivalents. On a quarterly schedule the installment is $8,619.33 per quarter, which is $2,873.11 a month, giving PITI of $3,573.11 and a DTI of 45.73%. Reporting the quarterly installment itself as PITI would mix units and inflate the ratio past 100%, which is why this page converts first and says so.
Worked example, checked against this exact tool
Borrow $400,000 at 6% for 20 years with monthly payments. The monthly rate is 0.5% and there are 240 payments, giving $2,865.72 per installment and $287,773.82 of total interest. Add $6,000 annual property tax and $2,400 annual insurance and PITI is $3,565.72 per month. With $10,000 monthly income and $1,000 of other debts, the debt-to-income ratio is 45.66%. Farm income of $200,000 against $150,000 of expenses leaves $50,000 of net farm income; annual debt service is $34,388.69, so the DSCR is 1.45. Enter these values above and the tool returns exactly these numbers.
Switch the same loan to quarterly payments and the installment becomes $8,619.33 per quarter, with total interest of $289,546.34. Switch it to annual payments and the installment is $34,873.82 per year, with total interest of $297,476.46. The longer the gap between payments, the more interest accrues between them, which is why the annual schedule costs the most even though the rate and term never change. The DSCR barely moves across schedules (1.45 monthly and quarterly, 1.43 annual) because annual debt service is nearly the same either way.
Farmland buyers often sanity-check a deal per acre: divide annual debt service by the acreage and compare with local cash rents and USDA land-value reports. In the worked example, $34,388.69 over 200 acres is $171.94 per acre per year. If the per-acre loan cost exceeds what the ground can rent for, the purchase is betting on appreciation, not income. That is a legitimate bet, but it should be a conscious one. The dairy farm profit calculator helps on the income side of that comparison when the operation is dairy.
DSCR bands: the ratio your ag lender actually reads
The debt-service coverage ratio divides net farm income by annual debt service. It answers the lender’s real question: does the farm itself generate enough cash to cover this loan?
| DSCR | Reading | What it means for your file |
|---|---|---|
| 1.20 or above | Strong | Comfortably above the comfort zone most ag lenders want. |
| 1.00 to 1.19 | Tight | Covers debt service but leaves little cushion for a bad year. |
| Below 1.00 | Shortfall | Farm income does not cover annual debt service. |
Two cautions belong with that table. First, some lenders set their bar at 1.25 rather than 1.20, so a 1.22 is strong by this tool’s verdict and still short at a stricter lender. Second, a DTI under 43 to 45% keeps the personal side acceptable, but on a farm loan the DSCR carries more weight than it does on a residential file. Check the personal-income side separately with the debt-to-income ratio calculator.
USDA and FSA loans change the down payment math
Before assuming 20% down, check the USDA Farm Service Agency loan programs. FSA direct farm ownership loans can go to borrowers who cannot get commercial credit elsewhere, with terms and down payments far below commercial norms, and dedicated funding exists for beginning farmers. The calculator’s numbers still apply; what changes is how much you must put down and which rate you qualify for. Note the distinction that trips people up: FSA farm ownership loans finance farms, while the USDA housing loan program finances rural homes. They are different programs with different rules, and only the farm program fits a working farm purchase.
What the worked example costs each year
Annual figures make the trade-offs concrete. On the monthly schedule in the worked example, the yearly cost breaks down as follows, and the bars are drawn to scale.
Total carrying cost is $42,788.69 a year before operating expenses. Against $50,000 of net farm income, that leaves $7,211.31 of headroom after the loan, tax and insurance are paid, which is exactly what a 1.45 DSCR feels like in cash terms: covered, with room for one mediocre year, but not for two.
What competing calculators miss
Generic mortgage calculators force monthly payments and ignore farm cash flow entirely. The farm-specific tools each cover half the picture: one computes DSCR from farm income but skips PITI, another models annual payments for the farm reality but never runs a DTI check, and the rental-property DSCR tools divide rent by PITIA, which answers a landlord’s question, not a farmer’s. This page does both sides at once: the full lender view of PITI, DTI and DSCR, on monthly, quarterly or annual schedules, with total interest so you see the true cost, and with PITI and DTI converted to monthly equivalents so the ratios mean the same thing on every schedule. If a second loan is part of the structure, the commercial mortgage calculator covers the business-property side of that leg.
Frequently asked questions
With standard amortization: payment equals P times r divided by (1 minus (1 plus r) to the power of minus n), where r is the periodic rate and n is the number of payments. A $400,000 loan at 6% over 20 years with monthly payments is $2,865.72 per month.
Commercial ag lenders commonly require a larger down payment than residential mortgages, because farmland is harder to appraise and resell. USDA Farm Service Agency programs can require far less for eligible beginning farmers.
The debt-service coverage ratio: net farm income divided by annual debt service. It shows whether the farm itself covers the loan payments. Ag lenders generally want around 1.20 or better, though some lenders use 1.25 as their bar, so treat 1.20 as a comfort zone, not a universal approval line.
Many farm loans are structured with quarterly or annual payments timed to harvest income. This calculator amortizes on monthly, quarterly or annual schedules so the payment matches your cash flow. PITI and the debt-to-income ratio are always shown as monthly equivalents, so they stay comparable across schedules.
Principal and interest plus property tax on the land and buildings, plus farmowners insurance. With a $400,000 loan at 6% for 20 years, $6,000 tax and $2,400 insurance, PITI is $3,565.72 per month.
Larger typical down payments, rates slightly above residential, seasonal payment schedules, and underwriting centered on farm cash flow (DSCR) rather than just salary-based DTI.
The USDA Farm Service Agency offers direct and guaranteed farm ownership loans, including dedicated funding for beginning farmers who cannot obtain commercial credit.
Divide annual debt service by the acres you are buying. In the worked example, annual debt service of $34,388.69 spread over 200 acres is $171.94 per acre per year. Compare that figure with local cash rents and USDA land-value reports before deciding the ground pays for itself.
