How to Calculate Your Refinance Break-Even Point
If you only learn one number before refinancing, make it your break-even point. It tells you exactly how long it takes for a refinance to start paying for itself — and it's the cleanest way to know whether refinancing is a smart move or an expensive mistake.
What the break-even point means
Refinancing isn't free. You pay closing costs up front, and in return you (hopefully) lower your monthly payment. Your break-even point is the moment your accumulated monthly savings finally equal those upfront costs. Before that point, you're still in the hole. After it, every month of savings is pure benefit.
A step-by-step example
Say you currently owe $320,000 at 6.875%, and you're offered a new 30-year loan at 5.75%. Here's how the break-even math plays out.
The numbers
| Current monthly payment (principal & interest) | $2,102 |
| New monthly payment (principal & interest) | $1,867 |
| Monthly savings | $235 |
| Closing costs | $6,000 |
| Break-even point | 26 months |
Dividing $6,000 in closing costs by $235 in monthly savings gives roughly 26 months — about two years and two months. If you plan to stay in the home longer than that, the refinance puts money back in your pocket. If you might sell sooner, it likely costs you.
(These figures are illustrative. Your actual payments depend on your exact balance, rate, and term — run yours through the calculator for real numbers.)
What counts as "closing costs"
To get an accurate break-even, you need the full cost figure, not just the obvious fees. Typical refinance closing costs include the loan origination fee, appraisal, credit report, title search and title insurance, recording fees, and any discount points you choose to buy. They usually total 2% to 5% of the loan amount. Our closing costs guide covers each line in detail.

- Comparing the wrong payments. Use principal-and-interest only. Don't mix in taxes and insurance, which don't change just because you refinanced.
- Ignoring the term reset. A lower payment on a longer term can mean more total interest. Break-even tells you about closing costs; also check lifetime interest before deciding.
- Forgetting rolled-in costs. If you fold closing costs into the loan instead of paying cash, you're financing them — which slightly changes the true savings.
A good rule of thumb
Many homeowners look for a break-even point under three years, since that's a reasonable horizon to be confident you'll still own the home. But the "right" break-even depends entirely on your plans. A five-year break-even is fine if you're settled for the long haul; a one-year break-even might still be too long if you expect to move soon.

Calculate your break-even point instantly →The bottom line
Your break-even point turns a fuzzy "should I refinance?" into a clear yes or no. Total up your closing costs, find your true monthly savings, divide one by the other, and compare the result to how long you'll stay. That one calculation does most of the decision-making for you.
