How to use Mortgage Calculator
- Enter the loan amount, interest rate, and term.
- The monthly payment, total interest, and full amortization schedule calculate instantly.
- Adjust any input to see how a different rate, term, or down payment changes your payment.
Example
$400,000 loan at 6.5% over 30 years: gives a monthly principal + interest payment around $2,528 — the tool also breaks out cumulative interest paid over the life of the loan.
Limitations
- Covers principal and interest only — property tax, homeowners insurance, PMI, and HOA fees vary by location and lender and aren't included unless you add them manually.
