The formula

Monthly saving = current payment − new payment. Break-even = closing costs ÷ monthly saving. It is worth it if break-even is within the years you will stay.

Frequently asked

Questions about the should i refinance calculator

Should I refinance my mortgage?

Refinancing pays off when the monthly saving recoups the closing costs before you move or sell. The calculator gives a clear yes, no, or borderline based on your numbers.

What is the refinance break-even point?

The number of months of lower payments needed to cover the closing costs. Stay past it and you come out ahead; sell before it and you lose money on the refinance.

Can refinancing cost more even at a lower rate?

Yes — resetting to a fresh 30-year term can raise total interest even if the payment drops. Check the lifetime interest, not just the monthly saving.

Is the Should I Refinance Calculator free to use?

Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
