Adjust the inputs below. This calculator estimates principal & interest only — the loan repayment itself. It does not include property taxes, homeowners insurance, PMI, or HOA dues, which lenders often bundle into your monthly escrow. Use it to understand the loan, then talk to your lender for an all-in figure.

Your “monthly payment” in a lender’s quote is usually larger than what this calculator shows, because lenders quote PITI — principal, interest, taxes, and insurance — often with PMI and HOA dues layered on top. This calculator isolates the part that actually pays down the loan: principal & interest (P&I).

Each month, part of your P&I payment covers the interest accrued on the outstanding balance, and the rest reduces the principal. Early in the loan most of the payment is interest; over time the balance shifts toward principal. The amortization table above shows that shift year by year. The figures it excludes — property taxes, homeowners insurance, PMI, and HOA dues — are real costs you should budget for separately, and they can add hundreds of dollars to your actual monthly outlay.
