How to Calculate Refinance Break-Even in 60 Seconds
TL;DR: Refinance math is one simple division: total closing costs divided by monthly savings. If the answer is fewer months than you'll stay, refinance wins.

If you're wondering whether refinancing your mortgage makes financial sense, the honest answer is: one division tells you. Add up all the closing costs on the new loan, subtract your new monthly payment from your old one, and divide costs by savings. That's the number of months to break even. If it's fewer months than you'll live in the house, refinance wins.
Okoniq Property Hub has a built-in refinance analyzer so you can run the numbers with a real Loan Estimate side-by-side. Here's the math to sanity-check any lender's pitch.
What goes into "closing costs"?
Every fee the lender will collect at closing. On a Loan Estimate (the standardized disclosure lenders must give you within 3 business days of application), look at:
- Origination charges (points, application fee, underwriting)
- Appraisal
- Title insurance (lender's policy)
- Title/escrow settlement fees
- Recording fees and transfer taxes
- Prepaid interest (a partial month of interest at closing)
- Any lender credits (negative — reduces total)
Skip the prepaid escrow (property tax and insurance) — that's not a cost of refinancing; it's just money you owe anyway sitting in the new escrow account.
A realistic total for a $250,000 refinance is $3,000–$6,000. Ranges vary by state and lender.
What are the monthly savings?
Old monthly principal + interest minus new monthly principal + interest.
Don't include escrow — property tax and insurance don't change because you refinanced. Only P&I.
Example: your current loan is $250,000 at 7.5%, $1,748/month P&I. Refinance to $250,000 at 6.5%, $1,580/month P&I. Savings = $168/month.
How do I do the division?
Closing costs ÷ monthly savings = months to break even.
Example: $4,500 closing costs ÷ $168 savings = 26.8 months — about 2¼ years. If you'll be in the home 5+ more years, refinance wins by a comfortable margin. If you might move in 2 years, it's a coin flip. If you might move in 1 year, don't refinance.
What if I don't want to write a check at closing?
You can roll closing costs into the loan balance ("no-cash-out refinance with costs financed") or accept a slightly higher rate for a lender credit ("no-closing-cost refinance"). Both change the math — a lender credit raises the monthly payment slightly, extending break-even, but avoids paying anything upfront.
For homeowners planning to move within 2–3 years, a no-closing-cost refinance with a modest rate improvement can still be worth it because break-even is essentially "day one." See should I refinance if I'll move in 3 years? for that specific scenario.
What break-even doesn't tell you
Break-even ignores two things worth mentioning:
- The remaining term. Refinancing a 25-year-remaining loan into a fresh 30-year extends your total interest paid, even at a lower rate. Consider a 20 or 15-year new loan if you're comfortable with the higher payment.
- Opportunity cost. Dollars spent on closing costs aren't earning returns elsewhere. Small factor, but real.
For a more complete picture, run the numbers through the Okoniq refinance analyzer or a lender's official Loan Estimate. The Consumer Financial Protection Bureau's mortgage tools are also excellent free resources.
Run your refinance numbers before you commit
Refinancing is one of those decisions where the marketing pitch ("save $X per month!") and the math ("but you'll pay $Y in costs and move in 3 years") often disagree. Okoniq Property Hub's refinance analyzer keeps it honest. Related: recast vs refinance — what's the difference? and the Mortgage & Money hub.
Frequently asked questions
What's a "good" break-even?
Under 24 months is generally strong. 24–48 months is fine if you're staying at least 5+ years. Over 60 months means the refinance only pays off if you stay in the home a long time.
Do points count as closing costs?
Yes — points are prepaid interest, and they belong in the closing-cost total for break-even math. Sometimes points make sense (you get a lower rate that pays back over the life of the loan), but they always extend break-even.
Does refinancing hurt my credit?
A hard inquiry drops your score by a handful of points temporarily. Not a reason to avoid refinancing when the math works.

FAQ
How long does it take to recoup refinancing costs on average?
Most homeowners break even between 2 and 4 years, depending on closing costs and how much the new rate lowers the monthly payment. If your break-even is under 24 months and you plan to stay 5+ years, refinancing is usually a safe bet.
Can I refinance again before I hit break-even on my current refinance?
Yes, but you'd be stacking two sets of closing costs without recovering the first. It only makes sense if rates drop dramatically — say another full percentage point — and you plan to stay long enough to recoup both rounds of fees.
What happens to my break-even if I choose a 15-year loan instead of 30?
The monthly payment goes up significantly, which can shrink or eliminate your monthly "savings" compared to your old loan, making break-even longer or nonexistent in monthly terms. However, you save tens of thousands in total interest over the loan's life, so the trade-off depends on cash flow versus long-term wealth.
Do I still break even if I sell the house exactly at my break-even month?
Yes — you've recovered every dollar spent on closing costs through lower payments. Every month beyond break-even is pure gain. Selling earlier means you lose money; staying longer means you keep saving.
