How monthly mortgage payments are calculated
For a fixed-rate amortizing loan, payment uses the standard formula: M = P × r(1+r)^n / ((1+r)^n − 1), where P is principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of months. If the rate is zero, the payment is simply principal divided by months. This page shows estimated monthly payment, total interest, and total amount paid over the full term.
What this estimate includes — and what it does not
The calculator covers principal and interest only. Real mortgage bills often add property taxes, homeowners insurance, mortgage insurance (PMI/MIP), HOA dues, and escrow adjustments. Treat the result as a starting point for budgeting, not a lender quote or APR disclosure.
How to use different currencies
Choose USD, EUR, GBP, CAD, AUD, INR, JPY, and other majors from the currency menu. Formatting follows local conventions (for example, yen without decimals). Currency selection does not convert exchange rates — enter the loan amount already denominated in the currency you care about, or convert separately with our currency converter.
Tips to lower a monthly payment estimate
A smaller loan amount, a lower rate, or a longer term reduces the monthly figure — but a longer term usually increases total interest. Compare a few scenarios here, then stress-test against taxes and insurance before deciding what is affordable.

FAQ
How do I calculate a monthly mortgage payment?
Enter the loan amount (principal), annual interest rate, and term in years. The calculator applies the amortization formula and returns an estimated principal-and-interest payment plus total interest over the life of the loan.
Does the mortgage calculator include taxes and insurance?
No. It estimates principal and interest only. Add local property tax, insurance, and any HOA or mortgage insurance on top for a full housing-cost picture.
Can I calculate mortgage payments in EUR, GBP, or INR?
Yes. Select your currency to format amounts. Enter the principal in that currency; the math is the same regardless of currency code.
Is a longer mortgage term always better?
Longer terms usually mean lower monthly payments but more total interest. Shorter terms cost more each month and less overall if you can afford them.
Is this mortgage calculator financial advice?
No. Results are educational estimates. Confirm rates, fees, and eligibility with a licensed lender or advisor in your country.
Is the Mortgage Calculator free?
Yes. It runs in your browser with no account required.
