How the monthly payment is calculated
This is the standard fixed-rate payment formula. It gives the payment that pays the loan off in full over the term.
- Loan amount
The purchase price minus the down payment. The down payment can't be more than the price.
Price − down payment
- Monthly principal and interest
The monthly rate is the annual rate divided by 12. The number of payments is the term in years times 12.
Loan × r ÷ (1 − (1 + r) ^ −n)
- What's not in it
Property taxes, homeowners insurance (and flood or wind coverage in parts of Florida), mortgage insurance and HOA dues. Add them for the full monthly housing cost.
Worked example: $500,000 home
$100,000 down, 6.5% fixed for 30 years.

What a rate change does
On the $400,000 loan in the example, each half point moves the payment about $130 a month.
- 6.0% for 30 years: $2,398 a month
- 6.5% for 30 years: $2,528 a month
- 7.0% for 30 years: $2,661 a month
- 6.5% for 15 years: $3,484 a month

When agents run a payment
At the open house
A visitor asks what this one would cost a month. Give a principal and interest number, then point them to a lender.
Choosing a price range
Run the same buyer at three prices so they see where the payment gets uncomfortable.
When rates move
Rates drop a quarter point. Call your buyers with the new payment for the home they liked.

Questions agents ask
How is a monthly mortgage payment calculated?
Divide the annual rate by 12 to get the monthly rate, r. Multiply the term in years by 12 to get the number of payments, n. The payment is the loan times r, divided by 1 minus (1 + r) to the power of minus n.
Does this calculator include taxes and insurance?
No. The web calculator shows principal and interest only. The mortgage calculator in the app adds property tax, homeowners insurance, PMI and HOA fees.
How much does a 1% rate change move the payment?
On a $400,000, 30-year loan, going from 6% to 7% raises principal and interest from $2,398 to $2,661 a month, about $263.
What's the payment on a 15-year loan?
Change the loan term to 15. At 6.5%, a $400,000 loan is $3,484 a month for 15 years, compared with $2,528 for 30 years.
Is this a loan quote?
