Land Loan Calculator

How the land mortgage payment calculator works

The financed amount is the land purchase price less the cash down payment. A fixed nominal annual interest rate is divided by twelve, and the resulting monthly rate is applied to a level principal-and-interest payment over the amortization period. One regular payment is assumed at the end of each month.

Use this land loan estimator for a monthly amortizing scenario with one fixed rate. It does not select a lender, infer a down payment requirement, or obtain an address-based land value. Compare entered offers on the same basis, including the separate maturity term and the costs paid at acquisition.

Amortization period versus land loan maturity

Amortization controls the size of the regular monthly payment. Maturity controls when the remaining principal must be settled. With a 30-year amortization and a 10-year maturity, the payment follows a 30-year schedule, but principal remaining after 120 scheduled payments appears as the balloon balance.

When maturity equals amortization, the modeled loan is paid off through regular payments. If the entered maturity is longer, the calculator stops payments at full amortization rather than continuing to charge them. A balloon is displayed separately from ordinary payments so the final cash requirement is explicit.

Land down payment, LTV, and closing costs

LTV divides financed principal by the entered purchase price. This price-based ratio does not establish a lender’s appraised-value ratio or approval limit. A $200,000 price and $50,000 down payment create a $150,000 loan and 75% modeled LTV; changing closing costs does not change those amounts.

Cash required at acquisition includes the down payment, origination fee, and other entered closing costs. At a 1% fee on that $150,000 loan and $4,000 in other costs, the acquisition cash estimate is $55,500. Do not put the origination charge into other closing costs as well, and do not assume fees are financed.

A worked land loan and balloon example

For a $200,000 parcel, a $50,000 down payment, a 6% fixed annual rate, 20-year amortization, and a 5-year maturity, the modeled loan is $150,000. Monthly P&I is about $1,074.65. After 60 payments, the remaining balloon is about $127,349.40.

Scheduled payments through maturity total about $64,478.80; adding the balloon produces about $191,828.19 in debt payments and $41,828.19 in interest. Origination and closing costs are separate acquisition outlays, not interest. Displayed values are rounded independently; the calculations use unrounded payments and balances.

Raw land, commercial parcels, and financing assumptions

Raw land, improved lots, commercial parcels, and agricultural properties can have different financing terms. This calculator uses the same payment mathematics when the actual agreement is fixed-rate and monthly amortizing. It does not estimate the effect of zoning, road access, utilities, permitted uses, or a future construction budget.

Methodology reviewed October 1, 2026: the model reuses EstateCalc’s tested fixed-rate acquisition-loan schedule. Rate resets, seasonal or annual payment schedules, and construction advances require different cash-flow timing and remain outside it. A 30-year input is a scenario you enter, not a claim that a lender offers that term for your parcel.
