15-year vs 30-year mortgage

The 15-year loan costs far less in total interest and far more each month. The right choice depends on your budget, your other goals and how much flexibility you want.

Key takeaways

  • On $300,000 at the same 6.5% rate, the 15-year payment is $2,613.32 and the 30-year is $1,896.20, a difference of $717.12 a month.
  • Total interest is about $170,398 on the 15-year and $382,633 on the 30-year, a saving of about $212,235.
  • 15-year loans usually carry a lower rate, which widens the saving, but the higher payment affects how much you can qualify for.
  • A 30-year loan with extra payments gives you a similar payoff with more flexibility.

Why the 15-year saves so much

A shorter term means the balance falls faster, so less interest is charged on it, and each payment sends more to principal. See how amortization works for the month-by-month split.

What the 30-year gives you

Who the 15-year suits

People with stable income who can comfortably afford the higher payment, already have an emergency fund, and value being debt-free sooner. Check that the payment still fits after taxes, insurance and any PMI; see the full payment breakdown.

Middle options

You can take a 30-year loan and pay it like a shorter one, use a 20-year term, or switch to bi-weekly payments. Lenders may price each term differently, so compare quotes.

Compare your own numbers, including the break-even investment return, in the 15 vs 30 year calculator, or test a lower rate after refinancing with the refinance calculator.
