Understanding the Mortgage Payment Formula
This calculator uses the standard amortization formula: M = P × [i(1+i)^n] ÷ [(1+i)^n − 1]
Where M is your monthly payment, P is the loan principal (home price minus down payment), i is your monthly interest rate (annual rate ÷ 12), and n is the total number of payments (years × 12). This is the same formula used by banks and mortgage lenders. If you've been wondering how to calculate mortgage payment amounts, this tool does the math for you instantly.
