What this calculator does
The Refinance Break-Even Calculator estimates how long monthly savings from a new loan may take to recover the upfront costs of refinancing.
How to use the calculator step by step
Enter the total refinance costs and estimated monthly savings between the current and proposed loans. Use realistic closing costs rather than only one lender fee.
How the calculation works
Simple break-even months equal total refinance cost divided by monthly savings. A 3,600 refinance cost with monthly savings of 150 produces a break-even period of 24 months.
Worked example and scenario testing
If closing costs are 5,000 and the new payment saves 200 per month, the simple break-even point is 25 months. Staying in the loan for five years would provide substantially more time after break-even than leaving after two years.
How to interpret your result
Break-even helps evaluate the upfront-cost tradeoff, but it does not by itself measure total lifetime interest or the effect of changing the loan term.
Accuracy, assumptions, and limitations
This simple method may not include opportunity cost, tax effects, changing escrow amounts, additional principal payments, lender credits, or differences in the remaining loan term.
Common mistakes to avoid
Do not calculate break-even using monthly savings that come mainly from extending the loan many additional years without also reviewing total interest.
