How to Calculate Your Mortgage Payment
The calculus behind mortgage payments is complicated, but Premier Mortgage Financial’s Mortgage Calculator makes this math problem quick and easy.
- Total Amount: Enter the price of the home (if you’re buying) or the current value of your home (if you’re refinancing).
- Interest rate: Type in the rate you expect to pay. Our calculator defaults to the current average rate, but you can adjust the percentage. Note the rate varies depending on whether you’re buying or refinancing.
- Loan term: Select the term — often 30 years, but maybe 20, 15, or 10 — to adjust the repayment schedule.

Typical costs included in a mortgage payment
The major part of your mortgage payment is the principal and the interest. The principal is the amount you borrowed, while the interest is the sum you pay the lender for borrowing it. Your lender also might collect an extra amount every month to put into escrow, money that the lender (or servicer) then typically pays directly to your local property tax collector and insurance carrier.
- Principal: This is the amount you borrowed from the lender.
- Interest: This is what the lender charges you to lend you the money. Interest rates are expressed as an annual percentage.
- Property taxes: Local authorities assess an annual tax on your property. If you have an escrow account, you pay about one-twelfth of your annual tax bill with each monthly mortgage payment.
- Homeowners insurance: Your insurance policy can cover damage and financial losses from fire, storms, theft, a tree falling on your home and other hazards. If you live in a flood zone, you’ll have an additional policy, and if you’re in Hurricane Alley or earthquake country, you might have a third insurance policy. As with property taxes, you pay one-twelfth of your annual insurance premium each month, and your lender or servicer pays the premium when it’s due.
- Mortgage insurance: If your down payment is less than 20 percent of the home’s purchase price, you’ll probably be on the hook for mortgage insurance, which also is added to your monthly payment.
