How to Calculate Your Mortgage Payments

Understanding how your monthly house payment is calculated is the first step to financial freedom.

The Mortgage Formula

The standard formula used to calculate a fixed-rate mortgage is:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]
  • M: Total monthly payment
  • P: Principal loan amount
  • i: Monthly interest rate (annual rate divided by 12)
  • n: Number of months
