Given my current rate, is refinancing actually worth it?
It comes down to one comparison: will the monthly savings pay back the closing costs before you sell or pay off the loan? If the rate you can get now is enough below your current one to do that, a refinance can pay off. If it's only a little lower, the costs may outweigh the savings. There's no official rate drop you need; the half-point to full-point rule of thumb is only a starting point.
Last updated September 29, 2026How do I tell whether a refinance pays off?
Divide your closing costs by your monthly savings. The answer is the number of months it takes to break even. If you'll keep the loan longer than that, the refinance is more likely to be worth it. If you expect to move or refinance again sooner, it probably isn't.
Here's an example. On a $300,000 balance, dropping from 7% to 6.5% on a new 30-year loan lowers principal and interest by about $100 a month. With $6,000 in closing costs, that's about 60 months to break even. On a $150,000 balance, the same rate drop saves about $50 a month, and breaking even takes about 120 months.
Is there an official rate-drop threshold?
No. No government rule sets a required drop. The "half a point to a full point" guideline is an industry rule of thumb. As the example shows, the balance matters: a bigger loan can justify a smaller rate cut, while a smaller loan needs a bigger one to break even in the same time. Your closing costs move the math too.
What if the best rate I can get is only a little lower?
Then the monthly savings may be too small to recover the closing costs in the time you'll keep the loan. Run the break-even math with a real quote, and compare it with how long you expect to stay.
It depends on your situation:
- The new rate is well below your current rate: the savings are more likely to recover the costs in a reasonable time.
- The new rate is only slightly lower: the costs may take longer to recover than you'll keep the loan.
- You have a large balance: a smaller rate cut can still pay off, because savings grow with the balance.
- You have a small balance: you'll need a bigger rate cut to break even as quickly.
- You'll stay a long time: more time for the savings to outweigh the costs.
- You'll move soon: less time to recover the costs.
| Break-even | Closing costs divided by monthly savings equals months to break even |
|---|---|
| Rule of thumb | A half point to a full point lower; not an official standard |
| Example: $300,000, 7% to 6.5% | About $100 a month saved; about 60 months to recover $6,000 |
| Example: $150,000, 7% to 6.5% | About $50 a month saved; about 120 months to recover $6,000 |
