Use this free mortgage calculator online to estimate your monthly principal-and-interest payment based on your home price, down payment, interest rate, and loan term. Adjust the numbers to compare mortgage payment scenarios and understand how your loan amount and repayment period affect your estimated monthly cost.
Calculate Your Monthly Mortgage Payment
Your monthly mortgage payment depends mainly on the amount you borrow, your interest rate, and the length of your loan. A larger down payment reduces the loan amount, while a lower interest rate can reduce the monthly payment.
Choosing a shorter loan term generally increases the required monthly payment but reduces the time spent repaying the mortgage.
This free online mortgage calculator estimates your monthly principal-and-interest payment using the loan details you enter. It also provides an amortization breakdown showing the estimated principal, interest, and remaining balance for individual months.
Understand Principal, Interest, and Your Remaining Balance
Each scheduled mortgage payment covers interest on your outstanding balance, with the remainder going toward principal. Early in a typical fixed-rate mortgage, a larger share of the payment goes toward interest. As the balance decreases, more of each payment goes toward principal.
Use the calculator’s monthly breakdown to review the estimated principal, interest, and remaining loan balance over time. For a more detailed view of how payments change throughout the loan, explore the mortgage amortization calculator.
Compare Loan Terms and Down Payments
Try different down payment amounts, interest rates, and repayment periods to see how they affect your estimated monthly payment. A 15-year mortgage typically has higher monthly payments than a 30-year mortgage with the same loan amount and rate, but it generally results in less total interest over the life of the loan.
To explore your options further, use the mortgage affordability calculator to estimate a suitable home-buying budget or the down payment calculator to compare upfront payment amounts.
Use This Free Online Mortgage Calculator to Plan Ahead
Enter your figures and select Calculate My Payment to estimate your monthly mortgage payment and review the amortization details. Comparing several scenarios can help you understand the trade-offs between borrowing less, choosing a different loan term, and accepting a different interest rate.
This free mortgage calculator estimates principal and interest for a standard fixed-rate loan. It does not include property taxes, homeowners insurance, private mortgage insurance (PMI), HOA fees, or closing costs.
For a broader payment estimate, use the mortgage calculator with taxes and insurance. Actual payments depend on your final loan terms and other applicable costs.
