About Mortgage calculator
Estimate monthly mortgage payment and amortization schedule from loan amount, rate, and term — principal and interest only.
Home loan shopping usually starts with one question: what is the monthly principal-and-interest payment. The standard amortizing formula uses principal, monthly rate, and number of payments. This page runs that math and optionally walks an amortization schedule so you can see how early payments lean toward interest.
Taxes, homeowners insurance, and HOA dues are not included. Lenders often quote PITI; this calculator is the PI slice. If your escrow is known, add it yourself after you have the P&I number. Closing costs and points are also outside the payment formula unless you bake them into a higher loan amount.
The same amortize engine powers the personal/auto loan calculator. This page keeps home-loan framing and SEO so people searching for a mortgage payment calculator land somewhere that talks about houses, not car notes. Neither page phones a credit bureau or stores your numbers.
How to use Mortgage calculator

- Fixed rate for the full term; no ARM schedules.
Common questions
Are property taxes and insurance included in the payment?
No. The payment here is principal and interest only. Add tax and insurance separately if you need a full PITI estimate.
Does this include extra principal payments?
The schedule assumes the regular payment only. Modeling biweekly or lump-sum prepayments would need extra controls this page does not ship yet.
Is this the same math as the loan calculator?
Yes — same amortizing loan formula. The loan calculator is framed for personal and auto loans; this one is framed for mortgages.
