Mortgage Calculator

Work out a monthly mortgage payment from a loan amount, an interest rate and a loan term, with total interest and total payment shown too.

Use the tool
Monthly payment: 0Total payment: 0Total interest: 0

This is a simple payment estimate for principal and interest only. Taxes, insurance and fees are not included, and actual lender terms may differ.

A mortgage payment depends mainly on three numbers: how much you borrow, the interest rate, and how many years you take to repay it. A longer term lowers the monthly payment but raises total interest, while a shorter term does the opposite.

This tool works out the monthly payment for principal and interest only, plus total payment and total interest, so you can compare terms side by side before you talk to a lender.

How to Use This Tool

  1. Enter your loan amount: type the amount you plan to borrow.
  2. Enter your annual interest rate: type the rate as a percent, for example 6.5.
  3. Enter your loan term in years: type a term like 30 or 15.
  4. Click Calculate Payment: read the monthly payment, total payment and total interest.

Good Practice Tips

  • Compare terms: run the same loan at 15 years and at 30 years to see the interest difference.
  • Remember extra costs: taxes, insurance and fees are not in this estimate, so your real monthly bill may be higher.
  • Check the rate type: a fixed rate stays the same, while a variable rate can change over the loan term.
  • This is not loan advice: use the result for planning only, and confirm real terms with a lender.

Frequently Asked Questions

Does this include taxes and insurance?

No. This estimate covers principal and interest only. Taxes, insurance and fees are not included.

Why is total interest so high on a 30 year loan?

A longer term means more months of interest charges, so total interest rises even though the monthly payment falls.

Is this loan advice?

No. This is a simple planning estimate. Confirm real terms, rates and fees with a lender before you decide.
