Refinance break-even calculator

The only refinance question that matters: how many months until the new loan pays for itself? Enter your numbers and find out.

Quick answerBreak-even months = total closing costs ÷ monthly payment savings. If you'll keep the home longer than the break-even point, refinancing usually pays off. Below that, it often doesn't.

How to read your break-even point

If the calculator shows a break-even of 36 months and you plan to stay in the home for ten years, refinancing is very likely worth it. If you might sell in two years, those closing costs may never be recovered. This is why the break-even framing beats chasing the lowest advertised rate.

Frequently asked questions

What is a refinance break-even point?

It's the number of months it takes for your monthly savings from a lower rate to recoup the closing costs of the new loan. Break-even months = total closing costs ÷ monthly payment savings. If you'll keep the home past that point, refinancing typically makes financial sense.

Is refinancing worth it for a 1% rate drop?

Often, but not always. The honest test is the break-even point relative to how long you'll stay. A 1% drop on a large balance can save hundreds per month and break even within two years; on a small balance with high fees, the same drop may take longer than you plan to keep the loan.

Do closing costs make refinancing not worth it?

Closing costs (typically 2%–5% of the loan amount) are exactly what the break-even calculation accounts for. A 'no-cost' refinance rolls those fees into a higher rate or balance — it doesn't eliminate them, it just hides them. Always compare on break-even, not the headline rate.
