How the Land Loan Payment Is Calculated
The calculator uses the standard fixed-rate amortization formula: payment = P × r ÷ (1 − (1 + r)−n), where P is the loan amount, r is the monthly rate and n is the number of monthly payments. The loan amount is the land price minus your down payment. Cash to close adds your down payment and closing costs such as the survey, title policy, appraisal and origination fee.
Example: $150,000 of unimproved land with 25% down leaves a $112,500 loan. At 8.5% amortized over 15 years the payment is $1,107.83 a month, you pay about $86,910 in interest over the full term, and you need $40,500 at closing ($37,500 down plus $3,000 of costs).
