Refinance Break-Even Calculator
Enter your current loan balance, remaining term, interest rates, and closing costs. The calculator tells you how many months it takes for your monthly savings to outweigh the upfront cost of refinancing, the total interest you save over the life of the loan, and your net gain or loss at any point in time. You can also choose to roll some or all of the closing costs into the new loan to see how that changes the break-even date.
What is the refinance break-even point?
When you refinance a mortgage, you pay closing costs upfront (or roll them into the loan) in exchange for a lower interest rate and, typically, a lower monthly payment. The break-even point is the number of months it takes for the cumulative monthly savings to equal those upfront costs. Before that date you are still "in the red"; after it every month of savings is pure profit. For example, if closing costs are $6,000 and your payment drops by $200 per month, break-even arrives at 30 months (2.5 years). If you plan to sell or pay off the mortgage before then, the refinance costs you money rather than saving it.
How to use this calculator
Enter your current loan balance, the interest rate you pay now, and how many months of payments you have left. Then enter the new interest rate being offered and the term of the refinanced loan. Under "Closing costs", add discount points (a percentage of the loan), any origination fee, and other third-party costs such as appraisal and title insurance. Toggle "Roll closing costs into new loan" if you prefer to finance the costs rather than pay them upfront - this removes the out-of-pocket expense but slightly increases the new monthly payment and shifts the break-even calculation. The results show your monthly payment change, the total cost of the refinance, how many months until break-even, and a year-by-year comparison table.
Discount points and their effect on break-even
Discount points are prepaid interest: you pay 1% of the loan balance per point in exchange for a rate reduction (typically 0.125% to 0.25% per point, though the exact trade-off varies by lender and market). Points increase your upfront cost and therefore push the break-even date further out, but they can make sense if you plan to hold the loan for many years. Origination points, by contrast, are simply a lender fee and do not reduce your rate. This calculator treats both as part of your total closing costs and factors them correctly into the break-even arithmetic.
Rolling costs into the loan vs paying upfront
If you choose to roll your closing costs into the new loan, your principal increases by the cost amount. This means you pay interest on those costs for the life of the loan, but you avoid the immediate cash outlay. Rolling costs in is common when refinancers have limited liquid savings or when the cost amount is modest relative to the loan. The trade-off is a slightly higher monthly payment than if the loan principal were exactly your current balance, and a higher total interest bill. Whether to roll or pay upfront depends on how long you plan to hold the loan and your current cash position.
Break-Even Benchmarks
| Break-even period | Interpretation | Verdict |
|---|---|---|
| Under 12 months | Excellent - very quick payoff | Refinance strongly favored |
| 12 to 24 months | Good - recoups cost within 2 years | Refinance favorable |
| 24 to 36 months | Fair - worth it if staying 3+ years | Refinance likely worthwhile |
| 36 to 60 months | Moderate - requires 3-5 year horizon | Evaluate carefully |
| 60 to 84 months | Long - only if staying 7+ years | Proceed cautiously |
| Over 84 months | Very long - high risk of not recovering | Consider alternatives |

Frequently asked questions
What is a good break-even point for a refinance?
Most financial planners consider a break-even of 24 months or less to be excellent. Between 24 and 36 months is still generally worthwhile if you intend to stay in the home for several years. Beyond 60 months (5 years) you need to be confident you will hold the property long enough to recoup the costs, and beyond 7 years the refinance may not benefit you at all if there is any chance of moving or paying off the loan early.
How are refinance closing costs calculated?
Refinance closing costs typically run between 2% and 5% of the loan balance. They include lender fees (origination, underwriting), third-party fees (appraisal, title search, title insurance), government recording fees, and prepaid items such as homeowners insurance and property tax escrow. Discount points, if any, are added on top. You can usually see an itemised estimate in the Loan Estimate document your lender is required to provide within three business days of your application.
Should I refinance if my rate drops by only 0.25%?
A 0.25% rate reduction can still save money over time, but it produces a smaller monthly saving and therefore a longer break-even period. On a $300,000 loan, 0.25% saves roughly $45 per month, meaning $3,000 of closing costs would take about 67 months to recoup. Whether that works for you depends on how long you plan to stay in the home. A larger rate reduction of 0.5% to 1% or more generally produces a much more compelling case for refinancing.
Does extending my loan term affect the break-even calculation?
Yes. Refinancing into a longer term (for example, from 20 years remaining into a new 30-year loan) lowers the monthly payment, which shortens the break-even period. However, spreading the balance over more years means you pay more total interest even if the rate is lower. The net savings output shows the full interest comparison so you can weigh a short-term cash-flow gain against a longer-term interest cost.
What if my break-even point is beyond my remaining loan term?
If the break-even date falls after your current payoff date, the refinance costs you money on a pure payment-savings basis. That said, refinancing into a shorter-term loan at a lower rate can still save total interest even with a high break-even month count because you are also accelerating payoff. Use the total interest savings and net savings figures alongside the break-even month to get the full picture.
Can I do a no-closing-cost refinance?
Yes. Some lenders offer no-closing-cost refinances where the closing costs are covered by a slightly higher interest rate (a lender credit) rather than paid upfront or rolled into the loan. In that scenario your break-even is immediate on a cash basis, but the higher rate means you save less per month than you would with a standard refinance. Enter a $0 total closing cost to model this scenario, keeping in mind the new rate should reflect the lender-credit rate, which is typically 0.125% to 0.375% above the standard quoted rate.
