Formula: M = L·r / (1 − (1 + r)⁻ⁿ), where L is the loan amount, r is the monthly rate (annual rate ÷ 12) and n is the number of monthly payments (years × 12). If the rate is 0%, M = L ÷ n. Taxes, insurance and HOA are divided into monthly amounts and added. This is an estimate only; actual lender figures, fees, mortgage insurance and rates may differ.
