Break-Even Calculator: When Does Refinancing Pay Off?
Refinancing costs money upfront. When do you start saving?
The break-even point tells you exactly when you recover your closing costs and start profiting.
What Is the Break-Even Point?
Break-even is the number of months it takes for your monthly savings to equal your closing costs.
Formula:
Break-Even (months) = Closing Costs ÷ Monthly Savings
Example:
- Closing costs: $5,000
- Monthly savings: $250
- Break-even: 20 months
After 20 months, you've recovered your costs. Every payment after that is pure savings.

Why Break-Even Matters More Than Rate
Most people focus on interest rate ("I'm getting 6.0% instead of 7.0%!").
But break-even is what actually determines if refinancing makes sense.
Example:
- Scenario A: Drop from 7.5% to 6.0%, save $360/month, $6,000 closing costs → 17-month break-even
- Scenario B: Drop from 6.5% to 6.25%, save $60/month, $5,000 closing costs → 83-month break-even
Scenario A is a no-brainer. Scenario B? You'd need to stay 7 years just to break even. Not worth it for most people.
Broker's Tip: I tell clients to aim for a break-even of 24 months or less. Anything longer is risky. Life happens — job changes, relocations, rate drops that trigger another refi.
How to Calculate Break-Even (Step-by-Step)
Step 1: Calculate Your Monthly Savings
Current monthly payment:
- Principal + Interest: $2,730
New monthly payment:
- Principal + Interest: $2,463
Monthly savings:
- $2,730 - $2,463 = $267
Note: Only compare principal + interest. Property taxes and insurance don't change when you refinance.
Step 2: Add Up Total Closing Costs
Typical closing costs:
- Origination fee: $4,000
- Appraisal: $500
- Title insurance: $1,200
- Lender fees: $800
- Total: $6,500
Get the exact number from your Loan Estimate (lenders must provide this within 3 days of application).
Step 3: Divide Costs by Savings
Break-even = $6,500 ÷ $267 = 24.3 months
Translation: You'll recover your closing costs in 2 years. After that, you save $267/month.
Step 4: Compare to Your Timeline
Are you staying 24+ months?
- Yes → Refinance makes sense
- No → You'll lose money
Not sure how long you'll stay? Build in a buffer. If break-even is 24 months, assume you need to stay at least 36 months to be safe.
Real Example: Break-Even Analysis
Current loan:
- Balance: $400,000
- Rate: 7.00%
- Payment: $2,661/month
- Remaining term: 28 years
Refinance offer:
- New loan: $400,000
- Rate: 6.25%
- Payment: $2,463/month
- Term: 30 years
- Closing costs: $5,200
Break-even calculation:
- Monthly savings: $2,661 - $2,463 = $198
- Closing costs: $5,200
- Break-even: 26.3 months (2.2 years)
Decision:
- Staying 2+ years? Refinance
- Selling in 18 months? Don't refinance (you won't recover costs)
What Affects Break-Even?
Factor 1: Closing Costs
Lower costs = faster break-even
Example:
- $3,000 closing costs ÷ $200 savings = 15-month break-even
- $6,000 closing costs ÷ $200 savings = 30-month break-even
How to lower closing costs:
- Shop lenders (rates and fees vary by 0.5-1%)
- Negotiate origination fees
- Consider a no-closing-cost refinance (you pay via higher rate)
See our no-cost refinance guide.
Factor 2: Monthly Savings
Bigger savings = faster break-even
Example:
- $5,000 costs ÷ $150 savings = 33-month break-even
- $5,000 costs ÷ $300 savings = 17-month break-even
How to increase monthly savings:
- Wait for rates to drop further (bigger rate reduction = bigger savings)
- Improve your credit score before applying (better rate)
- Pay down principal to hit 20% equity (drop PMI)
Factor 3: PMI Savings
If refinancing eliminates PMI, include that in your monthly savings.
Example:
- Payment drop: $100/month
- PMI eliminated: $150/month
- Total monthly savings: $250 (not just $100)
Break-even:
- $5,000 ÷ $250 = 20 months (instead of 50 months if you only counted the payment drop)
This is huge for FHA-to-conventional refinances. See our FHA vs conventional guide.
Break-Even vs Total Savings
Break-even tells you when you start saving. Total savings tells you how much you'll save long-term.
Example:
- Break-even: 24 months
- Monthly savings after break-even: $250
Total savings if you stay:
- 3 years: $3,000 (12 months × $250 after break-even)
- 5 years: $9,000 (36 months × $250)
- 10 years: $24,000 (96 months × $250)
- 30 years: $84,000 (348 months × $250)
The longer you stay, the more you save.
When Short Break-Even Doesn't Matter
Scenario: You're refinancing to cash out equity for a major expense.
Example:
- Current loan: $300,000 at 6.5%
- New loan: $380,000 at 6.75% (taking $80,000 cash)
- Payment increases by $150/month
- There is no break-even (you're paying more, not less)
But you needed the $80,000 for:
- Debt consolidation (paying off 22% credit cards)
- Home addition
- Down payment on rental property
In this case, break-even doesn't apply. You're not refinancing to save money monthly — you're refinancing to access equity.
See our cash-out refinance guide.
Adjusting for Loan Term Changes
If you're restarting your loan term, factor that into the equation.
Example:
- Current loan: $380,000, 25 years remaining
- New loan: $380,000, 30 years
You just added 5 years of payments. Even if your monthly payment drops, you'll pay more interest long-term.
Advanced break-even formula:
True Break-Even = (Total interest on new loan) - (Total interest on current loan) + Closing costs
Divide by monthly savings
This accounts for:
- Extended loan term
- Total interest paid over life of loan
- Upfront costs
Use our refinance calculator to model this.
Frequently Asked Questions
Q: What's a good break-even point?
24 months or less. Anything longer is risky unless you're 100% certain you'll stay.
Q: Should I refinance if my break-even is 36 months?
Only if you're confident you'll stay at least 5 years. Build in a buffer for unexpected moves or future refinances.
Q: Does break-even include property taxes and insurance?
No. Those costs stay the same. Only compare principal + interest.
Q: What if I'm doing a cash-out refinance?
Break-even doesn't apply if your payment is increasing. Instead, calculate whether the cash you're getting is worth the higher payment.
Q: Can I refinance again before hitting break-even?
Yes, but you'll lose money on the first refinance. Only do this if rates drop significantly (1%+) and the second refinance recovers both sets of closing costs.
