Use this 30-year fixed mortgage calculator to estimate your monthly principal and interest payment based on your home price, down payment, and interest rate. Adjust the inputs to compare borrowing scenarios and see how a long-term, fixed-rate mortgage may fit your housing budget.
How a 30-Year Fixed Mortgage Works
A 30-year fixed mortgage is repaid over 360 monthly payments. The interest rate remains fixed for the agreed loan term, so your scheduled principal and interest payment generally stays the same. This longer repayment period typically offers lower monthly payments than shorter-term mortgages, but it can result in more total interest over the life of the loan.
Understand Your Mortgage Results
- Monthly payment: Your estimated monthly principal and interest payment.
- Principal paid: The amount that reduces your loan balance during the selected year.
- Interest paid: The interest charged during that year.
- Remaining balance: The estimated amount you still owe at the end of that year.
Select a year in the amortization breakdown to review how much principal and interest you pay and how your outstanding balance changes over time.
How Your Inputs Affect Payments
Home price and down payment: Your down payment reduces the amount you borrow. Use our down payment calculator to compare different upfront payment amounts.
Interest rate: Your fixed rate affects your monthly payment and the total interest paid over 30 years. Learn how mortgage rates work before comparing offers from lenders.
Loan term: A 30-year term generally spreads repayment over more months than a shorter mortgage, lowering the required monthly principal and interest payment for the same loan amount and rate. Compare a 15-year mortgage to see how a shorter repayment period changes your estimated payment.
What This Mortgage Estimate Includes
This calculator estimates principal and interest only. It does not include property taxes, homeowners insurance, private mortgage insurance (PMI), homeowners association fees, or closing costs. Your total monthly housing expenses may therefore be higher than the result shown.
Use your estimate to assess affordability and compare loan scenarios. Before choosing a mortgage, consider both the monthly payment and the total interest you may pay over the full repayment period.
