Refinance Break-Even Calculator
Last updated July 2, 2026
Refinancing a mortgage to a lower interest rate reduces monthly payments and saves money over the life of the loan — but it costs money upfront to execute. Closing costs for a refinance typically run 2 to 5 percent of the outstanding loan balance, covering origination fees, appraisal, title insurance, and other expenses. The break-even point is the number of months it takes for the cumulative monthly savings to equal those upfront costs. Divide total closing costs by monthly savings to get break-even months: $6,000 in closing costs divided by $200 in monthly savings equals a 30-month break-even point. If you plan to stay in the home beyond 30 months after the refinance closes, refinancing is financially beneficial. If you're likely to move or refinance again before that point, the closing costs represent a net loss.
In 2026, with 30-year fixed mortgage rates hovering around 6.5 to 7 percent, refinancing primarily benefits homeowners who locked in rates above 7.5 to 8 percent in late 2023 and 2024. A rate-and-term refinance that saves 0.75 percent or more on a large balance can still produce meaningful break-even timelines under 36 months. The term reset is an important consideration that calculators often underweight: refinancing a loan that has 22 years remaining into a new 30-year loan extends the total repayment period and increases lifetime interest paid, even if the monthly payment is lower. Matching the new loan term to the remaining term on the old loan — or choosing a 15-year loan if the payment is manageable — captures the interest savings without extending the payback timeline.
The break-even calculation is the only number that determines whether a refinance makes financial sense. Divide your total closing costs by your monthly payment savings — if the resulting number of months is less than how long you plan to stay in the home, refinancing is worth it. Watch out for the term reset trap: a longer new term can mean more total interest even with a lower rate.
