Mortgage Refinance Break-Even: When Refinancing Actually Pays Off
Calculate your refinance break-even in months, compare rate-and-term against cash-out, and recognize when refinancing is the wrong move.
Divide your total closing costs by your monthly payment savings — if you will stay in the home longer than that many months, refinancing pays off.
What you'll walk away with
Skim these first — then dig into the details below.
- 1Break-even months = closing costs ÷ monthly payment savings.
- 2A rate drop of roughly 0.75–1% is the usual threshold worth pursuing.
- 3Resetting to a fresh 30-year term can increase total interest despite a lower rate.
- 4Cash-out refinancing raises your balance — reserve it for high-return uses.

Refinancing costs real money upfront. Break-even tells you when you start actually saving, and it is the only number that reliably prevents a bad refinance.
The calculation takes half a minute and requires just two inputs.
The break-even calculation
Use total closing costs, not just the lender fee.
- 1
Add all closing costs from the Loan Estimate — origination, appraisal, title, recording, points.
- 2
Subtract the new monthly payment from your current payment.
- 3
Divide costs by monthly savings to get break-even in months.
- 4
Compare that against how long you realistically plan to keep the home.
What the simple version misses
Break-even is a great filter, but a few adjustments make it more honest.
- Term reset: comparing payments alone hides the added years of interest.
- Costs rolled into the balance still cost you — with interest, for decades.
- If you were paying extra principal, keep doing so on the new loan or the savings evaporate.
- Escrow refunds and skipped payments at closing are timing, not savings.
Rate-and-term vs cash-out
Two different products with very different risk profiles.
- Rate-and-term: replace the existing balance with better terms; typically the lowest rate available.
- Cash-out: borrow more than you owe and take the difference in cash, usually at a higher rate.
- Cash-out makes sense for value-adding renovations or eliminating 20%+ APR debt with a real plan.
- It converts unsecured debt into debt secured by your home — the downside changes entirely.
When not to refinance
Sometimes the right answer is to keep the loan you have.
- You plan to move before break-even.
- You would stretch a 22-year remaining balance back to 30 years.
- The monthly savings are small enough that the paperwork and costs are not worth it.
- Your credit or income has weakened since you bought, so pricing would be worse.
