- Enter your current loan balance, rate, and remaining term — not the original loan, what you owe today.
- Enter the new rate you've been offered and the new term you're considering (refinancing into a fresh 30-year restarts the clock — the calculator shows that cost honestly).
- Add your closing costs (typically 2%–5% of the loan: origination, appraisal, title, taxes). Use a real Loan Estimate, not a guess.
- Read your break-even: months until the monthly savings have repaid the closing costs, plus lifetime interest saved or lost.

How the Math Works
Break-even is the simplest formula in lending:
Worked example: a $300,000 balance at 7.0% costs $1,996/month (P&I). Refinancing to 6.0% drops it to $1,799 — saving $197/month. With $4,800 in closing costs, break-even = 4,800 ÷ 197 ≈ 25 months. Stay past month 25 and you're ahead; sell or refinance again before it and you lost money. Monthly payments use the standard amortization formula lenders use, shown on our mortgage calculator page.
When Refinancing Actually Pays
| Scenario ($300k, 30-yr) | Payment | Savings/mo | Break-even ($4,800 costs) |
|---|---|---|---|
| 7.0% → 6.5% | $1,996 → $1,896 | $100 | 48 months |
| 7.0% → 6.0% | $1,996 → $1,799 | $197 | 25 months |
| 7.0% → 5.5% | $1,996 → $1,704 | $292 | 17 months |
Rule of thumb: refinancing tends to pay when you cut ≥0.5 points AND you'll keep the home past break-even. The "2% rule" is outdated — smaller cuts can still win on large balances.
Refinance Break-Even FAQ
Is refinancing worth it for 1%?
On a $300,000 balance, 1 point saves roughly $190–200/month, breaking even on typical closing costs in about 2 years — usually worth it if you plan to stay longer than that.
Should I refinance into another 30-year loan?
A fresh 30-year lowers the payment most but restarts amortization, raising lifetime interest. The calculator shows both paths — compare a matched-remaining-term scenario before deciding.
Can I roll closing costs into the loan?
Yes, but you then pay interest on them and your balance grows; break-even lengthens. Model it by adding the costs to the new loan amount.
What about no-closing-cost refinances?
They exist — the costs are exchanged for a higher rate. You avoid the break-even question entirely in exchange for smaller savings; run both quotes through the calculator.
Does my credit score change the answer?
It changes the new rate itself. Get rate quotes at your current score, then plug the real offer in — estimated savings are only as good as the quoted rate.
