Most US homeowners pay principal and interest (P&I) plus property taxes and homeowners insurance, often through an escrow account. This calculator focuses on the loan math; you can add tax and insurance estimates separately.
Fixed-rate mortgages use standard amortization: early payments are mostly interest, and later payments shift toward principal. A 30-year loan at 7% pays more interest over life than a 15-year loan at the same rate.
Start with the full mortgage calculator for a complete picture including down payment, tax, and insurance. Use the payment-only tool when you already know your loan amount and want P&I quickly.
The amortization schedule shows how each payment splits between interest and principal — useful for understanding equity build-up and total interest paid.
Results are estimates, not loan offers. Lenders apply underwriting, appraisal, and closing costs not modeled here. Consult a licensed mortgage professional before committing.
