How to Calculate Your Mortgage Payment: Formula Guide (2026)
How to Calculate Your Mortgage Payment Your monthly mortgage payment is determined by three numbers: the loan amount, the interest rate, and the loan term. The standard amortization formula M = P x r(1+r)^n / (1+r)^n - 1 converts these inputs into a fixed payment that fully repays the loan over time. On a $280,000 loan at 6.5% for 30 years, the formula produces $1,770 per month in principal and interest. At UseCalcPro, we've processed over 2 million mortgage calculations since launching.

That understanding is the difference between confidently negotiating with a lender and blindly signing paperwork. This guide walks through the math behind every mortgage payment, so you know exactly where each dollar goes.
