Refinance Break-Even Calculator
Find the month a refinance starts paying you back.
What this calculator helps you estimate
This calculator compares your current mortgage to a proposed refinance, showing the change in monthly payment, the month costs are recovered, and how re-amortizing affects interest and payoff timing.
A lower rate is only part of the picture. Closing costs, how far you are into your current loan, and whether the new term restarts the clock all shape whether a refinance is actually worth doing.

Break-even and long-term effect
Interpretation
At $225.96 per month in payment savings, the $6,500.00 in costs would be recovered in roughly 29 months. Selling or refinancing again before then generally means the costs are not recovered.
This refinance extends your payoff timeline beyond the 336 months remaining on your current loan. Re-amortizing lowers the payment but can increase total interest paid over the life of the debt, even at a lower rate.
Break-even is one input, not the decision. Weigh how long you plan to keep the home, whether costs are paid in cash or financed, mortgage insurance, and what else the cash could do.
Understand the math
How this calculator works
A lower rate is only part of the refinance decision — closing costs, how far along you are in your current loan, and whether the new term restarts the clock all matter. This calculator isolates the single number that answers the practical question: how long until it pays for itself?
Worked example
Current: $320,000 balance, 7.25% rate, 22 years remaining. Proposed: refinance $320,000 into a new 30-year loan at 6.4% with $6,500 in closing costs.
- Current payment (7.25%, 22 yrs) ≈ $2,428.46
- New payment (6.4%, 30 yrs) ≈ $2,001.62
- Monthly savings = $2,428.46 − $2,001.62 = $426.84
- Break-even = $6,500 ÷ $426.84 ≈ 15.2 months
Break-even in roughly 15 months — after that, the refinance produces net monthly savings.
How to read your results
Interpretation guidance
- Compare the break-even month to how long you realistically expect to stay in the home or keep this loan.
- This example resets the clock from 22 years remaining to a fresh 30-year term — note that trade-off even though the payment drops.
- Financing the closing costs into the new loan still uses the same break-even logic, just applied to a slightly larger balance.
- A rate drop that looks small in percentage terms can still produce a fast break-even on a large loan balance.

More questions about this calculator
How do I calculate a refinance break-even point?
Divide total closing costs by the monthly payment savings. Costs of $6,500 with $427 in monthly savings produce a break-even of roughly 15 months. Results are estimates for educational purposes only and are not a commitment to lend.
How much does a rate need to drop to justify refinancing?
There is no universal threshold — what matters is whether your savings recover the costs before you sell or refinance again. A small rate drop on a large balance can beat a large drop on a small one.
Does refinancing restart my loan term?
Usually yes. Refinancing a loan you've paid on for several years into a new 30-year term lowers the payment but stretches the debt out again, which can raise lifetime interest even at a lower rate.
Should I roll closing costs into the loan?
Financing costs preserves cash but increases the balance and the interest paid on it. The break-even month is still measured against total costs, whether paid at closing or financed.

Does a refinance affect my credit?
A refinance involves a credit inquiry and replaces an existing account with a new one, which can move a score modestly in the short term. Consistent on-time payments matter far more over time.
