How to Calculate Your Monthly Mortgage Payments Easily?.

To calculate your monthly mortgage payments, use the formula: M = P[r(1 + r)^n] / [(1 + r)^n – 1], where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate, and n is the number of payments.

Step-by-step

1. Determine the principal loan amount (P).
2. Find the annual interest rate and divide by 12 to get the monthly interest rate (r).
3. Decide on the loan term in years and multiply by 12 for the total number of payments (n).
4. Substitute P, r, and n into the formula to calculate M.
5. Review the calculation for accuracy.
