15-Year vs. 30-Year Mortgage Calculator

See the monthly bill, the interest cost and what you would still owe. Simple help for every number.

YOUR TWO LOAN OPTIONS

Same mortgage amount. Two ways to repay it.

Compare two new fixed-rate mortgages. Use a rate for each term; they can be different. This is not a comparison with your existing loan.

Example numbers are for learning, not live rates or lender offers.

15-year and 30-year loan assumptions

Home price minus your down payment.

Try 5 if you might move in five years.

For 6%, enter 6. Use the note rate, not APR.

For 6.5%, enter 6.5.

Add fees, insurance and your monthly budget

Optional costs start at $0, so they are left out until you add them. Use your lender estimates and monthly tax/insurance costs for a fuller comparison. Both loans use the same borrowed amount.

Use your Loan Estimate. Leave out your down payment.

Use the estimate for this loan, which may differ.

Ask your lender. Enter 0 if none applies.

Use this loan’s own insurance estimate.

Enter 0 when there is no mortgage insurance.

Five years × 12 = 60 months.

Add monthly amounts. Divide annual bills by 12.

0 means no budget check. Try your own spending limit.

YOUR ESTIMATED COMPARISON

A smaller bill or a faster payoff?

A 30-year loan spreads payments over more months. A 15-year loan ends sooner. Enter both rates to see the payment difference and the interest each option could cost.

We also compare the same years so you can see the mortgage still owed if you move before payoff.
