Mortgage Payment Calculator
Estimate a fixed-rate monthly principal-and-interest payment before you make a housing decision. Use it as a planning conversation, not as a lender quote.
Estimate your payment
How to use it
- Enter a possible purchase price and the cash you expect to put down.
- Use a rate you have actually been quoted or a conservative planning estimate.
- Compare the principal-and-interest result with your full household plan before deciding what is sustainable.
Assumptions and limitations
This reuses the site’s existing fixed-rate, monthly amortization formula. It estimates principal and interest only. It does not include property taxes, homeowners insurance, mortgage insurance, HOA dues, closing costs, repairs, lender fees, or changes to your income and expenses. Actual loan terms and eligibility come from a lender.
Questions readers ask
Why is my lender’s number different?
A lender may include escrow, insurance, fees, a different rate, and loan-specific terms. Ask for a written estimate and compare the categories, not only one monthly figure.
Does a larger down payment always make the home affordable?
It can reduce the amount borrowed, but affordability also depends on total housing costs, reserves, other obligations, and a margin for ordinary life changes.
