Leave the payment at 0 to reconstruct it from the balance, rate and years remaining. Enter the principal-and-interest figure from your statement for a comparison against what you actually pay.

Extending your payoff date can lower the monthly payment while increasing total interest. Compare Loan Estimates, APR and fees—not just the rate.

Look past the rate

What to enter

Put in what you still owe, your rate and how many years are left. Then the new rate, the new term and the fees. If you have your statement handy, enter the loan-and-interest payment from it. That is better than letting the tool work it out, because your real loan may not be running exactly to plan.

The fees and the years decide it

A lower rate does cut what you pay each month in loan and interest. But the lender fees, the title work and the appraisal have to be paid back out of that saving first. And swapping a loan with 20 years left for a fresh 30-year one lowers the payment while keeping you in debt a decade longer.

A worked example

Say the refinance costs you $6,000 up front and saves $250 a month. It takes 24 months to get that $6,000 back. Move house or refinance again before then and you never do.

Which number to look at

  • The monthly saving, if you need room in your budget now.
  • The payback time, against how long you plan to stay.
  • The lifetime cost, to catch a saving that only exists because the loan got longer.
  • Real offers from more than one lender, before you decide anything.

Common questions

Frequently asked questions

How is the break-even point worked out?+

It divides what you pay in fees by what you save each month. That tells you how many months it takes to get the fees back. It ignores tax effects and what that money could have earned elsewhere.

Can a smaller payment still cost me more?+

Yes, easily. Starting again over 30 years lowers the payment but adds years of interest. Look at the lifetime figure too, not just the monthly one.

What if I roll the fees into the loan?+

They get added to what you borrow, so there is no cash to earn back and no simple break-even month. You pay for them slowly, with interest on top.
