How to find your monthly mortgage payment
Your monthly mortgage payment is the amount you owe your lender each month. It includes principal (the money you borrowed), interest (what the lender charges for lending it), property taxes, homeowners insurance, and sometimes mortgage insurance. You can find this number three ways: ask your lender directly, use an online calculator with your loan details, or do the math yourself if you have a financial calculator.
The fastest route is to call or log into your lender's website. They will give you the exact payment for your specific loan. If you are shopping for a mortgage before you borrow, an online calculator gives you an estimate in seconds. If you want to understand how the number works, the manual calculation shows you what each part costs.
Key Takeaways
- Your lender can tell you your exact monthly payment in one phone call or through your online account.
- An online mortgage calculator estimates your payment if you know the loan amount, interest rate, and loan length.
- Your payment includes principal, interest, property taxes, homeowners insurance, and sometimes mortgage insurance — not just the loan itself.
- The principal and interest portion stays the same each month, but property taxes and insurance may change year to year.
- A financial calculator or spreadsheet can show you the math behind the payment if you want to understand where the number comes from.
Getting the number directly from your lender
Call the customer service number on your mortgage statement or log into your lender's online portal. Ask for your monthly payment amount. They will give you the total you owe each month. Many lenders also break down what portion goes to principal, what goes to interest, and what goes to taxes and insurance.
If you are a new borrower and have not yet closed on a loan, ask for a Loan Estimate. This is a document the lender must give you within three business days of your process. It shows your estimated monthly payment, broken down by component, plus all the costs you will pay at closing. The Loan Estimate is free and gives you the clearest picture of what you will owe.
Using an online calculator
An online mortgage calculator works if you know four numbers: the loan amount (how much you borrowed), the interest rate (the percentage the lender charges), the loan term in years (usually 15 or 30), and your property tax and insurance estimates. Plug these in and the calculator shows your monthly payment in seconds.
You can find these calculators on most bank websites, mortgage broker sites, and financial education sites. They are free and do not require you to enter personal information. The result is an estimate, not a may provide — your actual payment may differ slightly depending on your exact closing date, local tax rates, and insurance quotes. Use the estimate to compare loans or understand the range of what you might owe.
The parts of your monthly payment
Your payment has up to five parts. Principal is the portion that reduces what you owe on the loan itself. Interest is what the lender charges for lending you the money. In the early years of a 30-year loan, most of your payment goes to interest; in later years, more goes to principal.
Property taxes are set by your city or county and vary widely by location. Homeowners insurance protects your house and is required by your lender. Both are often collected by your lender each month and paid to the tax assessor and insurance company on your behalf. Mortgage insurance (PMI) is required if you put down less than 20 percent. It protects the lender if you stop paying, and it disappears once you have paid down the loan enough.
When someone quotes a mortgage payment, they usually mean the total of all five parts. When they break it down, they separate principal and interest from the taxes and insurance. Ask your lender which number they are quoting so you know what to expect.
Calculating the payment yourself
If you want to see the math, the formula for principal and interest is straightforward on a financial calculator or spreadsheet. You need the loan amount, monthly interest rate (annual rate divided by 12), and number of months (years times 12). Most spreadsheet programs like Excel or Google Sheets have a built-in PMT function that does this calculation.
For example, a $300,000 loan at 6.5 percent interest over 30 years breaks down as follows: divide 6.5 by 100 to get 0.065, then divide by 12 to get the monthly rate of 0.00542. Multiply $300,000 by this rate and divide by (1 minus (1 plus the rate) raised to the negative number of months). The result is your principal and interest payment. Then add your estimated property taxes and insurance to get the total.
This is more work than using a calculator, but it shows you why the payment is what it is. Early payments are mostly interest because you owe a large balance. As you pay down the principal, more of each payment goes toward reducing what you owe. A spreadsheet can show you this month by month in what is called an amortization schedule.
Why your payment might change
The principal and interest portion of your payment stays the same for the life of a fixed-rate loan. However, property taxes and homeowners insurance can increase. If your property taxes go up, your lender will adjust your monthly payment to collect more. If your insurance premium increases, the same thing happens. These adjustments usually happen once a year.
If you have an adjustable-rate mortgage (ARM), your interest rate and payment can change after an initial fixed period. The lender will notify you before the rate adjusts. If you have mortgage insurance, your payment will drop once you reach 20 percent equity in your home, though you may need to request this.
Comparing payments across different loans
When you are shopping for a mortgage, use the same calculator or your lender's quotes to compare. A lower interest rate reduces your monthly payment and the total amount you pay over the life of the loan. A longer loan term (40 years instead of 30) lowers the monthly payment but increases the total interest you pay. A larger down payment reduces the loan amount and your monthly payment.
Ask each lender for a Loan Estimate so you can compare apples to apples. The estimate shows the same information in the same format for every lender, making it straightforward to see which loan costs less per month and over time. Do not compare only the monthly payment — also look at the total interest and fees you will pay.
Frequently Asked Questions
What if I do not know my interest rate yet?
If you are pre-shopping, use the current average rate for your area as a placeholder. Mortgage rates change daily, so your actual rate will depend on when you lock in. Your lender can tell you the current rate and what it will be if you lock today. Use that number in your calculator for the most accurate estimate.
Does the payment include property taxes and insurance?
It depends on your loan. Most lenders collect taxes and insurance each month as part of your payment and hold the money in an account called an escrow. Some loans let you pay taxes and insurance separately. Ask your lender which way your loan works so you know what your actual out-of-pocket cost will be.
Can I pay more than the monthly payment?
Yes. Paying extra principal each month reduces the total interest you pay and shortens the loan. Some loans charge a prepayment penalty if you pay off the loan early, though this is rare on mortgages. Check your loan documents or ask your lender whether extra payments are allowed without penalty.
What happens if I miss a payment?
Your lender will charge a late fee, usually a percentage of your payment. After 30 days late, the missed payment shows on your credit report. After 120 days, the lender may start foreclosure. If you think you will miss a payment, contact your lender when ready — many have programs to help you catch up or temporarily lower your payment.
How do I know if my payment is correct?
Compare your mortgage statement to your Loan Estimate. The payment should match what was quoted. If property taxes or insurance changed, the payment may have adjusted — your statement will show the new breakdown. If the payment changed without explanation, call your lender and ask why.
