Refinance Break-Even Guide: Closing Cost Payback
Calculate refinance break-even point — how long to recover closing costs. Full guide with formulas, examples, and when refinancing actually saves money.
Refinance Calculator — Direct Answer
Refinance break-even = Closing costs ÷ Monthly savings = Months to recover. If closing costs are $4,500 and you save $150/month, break-even = 30 months. Refinancing makes sense if you'll stay in the home past the break-even point AND the rate reduction is at least 0.75%.

How to Calculate Refinance Break-Even
The break-even point is when cumulative savings equal closing costs.
Break-Even (months) = Closing Costs ÷ Monthly Savings
Monthly Savings = Old Payment − New Payment
Where:
- Closing Costs = all fees to close the new loan (2–5% of loan)
- Old Payment = current monthly payment
- New Payment = refinanced monthly payment
How to calculate monthly savings
Get your current payment and the proposed new payment. Subtract.
Example:
- Current payment: $1,896 (6.5% on $300K)
- Refinance payment: $1,610 (5% on $280K)
- Monthly savings: $286
How to calculate the break-even point
Example:
- Closing costs: $5,500
- Monthly savings: $286
- Break-even = 5,500 ÷ 286 = 19.2 months (~20 months)
If you plan to stay 5+ years, this refinance is a clear win.
How to apply to your situation
| Scenario | Break-Even | Verdict |
|---|---|---|
| Small rate drop (0.25%) | 5+ years | Rarely worth it |
| Moderate drop (0.75%) | 18–30 months | Usually worth it |
| Large drop (1.5%+) | 12–24 months | Almost always worth it |
| Cash-out | No break-even | Different analysis |

Common Refinance Mistakes
Mistake 1: Refinancing for a tiny rate drop
Refinancing to save 0.25% often costs more in closing costs than you save. Fix: Target at least 0.75% rate reduction to make refinancing worthwhile.
Mistake 2: Restarting the 30-year clock
Refinancing $280K back to a new 30-year term adds years of interest. Fix: Refinance into a 20- or 15-year term to actually save money.
Mistake 3: Rolling closing costs into the loan
Borrowing more to cover costs means paying interest on those fees. Fix: Pay closing costs out of pocket if possible, or negotiate them down.
Rate-and-Term vs Cash-Out Refinance
Rate-and-term refinance
- Purpose: Lower rate or change term
- Loan amount: Same or similar
- Best for: Reducing monthly payment
Cash-out refinance
- Purpose: Access home equity
- Loan amount: Higher than current loan
- Best for: Debt consolidation, renovations
Which should you choose?
Rate-and-term if you want a lower payment. Cash-out if you need cash and have equity.
Refinance Calculator FAQ
How do I calculate refinance break-even?
Break-even = Closing Costs ÷ Monthly Savings. If you save $200/month and costs are $5,000, break-even is 25 months.
When should I refinance?
Generally when your new rate is at least 0.75% lower than your current rate AND you plan to stay in the home past the break-even point (usually 18–36 months).
How much are refinance closing costs?
2–5% of the loan amount — typically $4,000–$15,000 for a residential mortgage.
Is refinancing worth it to lower payments?
Only if you stay past break-even. Otherwise closing costs outweigh savings.
Can I refinance with bad credit?
Yes, but you'll pay a higher rate. Improving your credit score first often yields better long-term savings.
