Break-even refinance calculator
See how long monthly savings take to offset upfront refinance costs.
Calculation notes
Methodology for the break-even refinance calculator
Calculate exactly how many months it takes for refinance savings to recover upfront penalty and fees — your breakeven point.
See whether refinancing pays off within your expected holding period or if waiting until maturity is smarter.
Model different penalty scenarios — standard IRD, posted-rate IRD, and 3-month interest.
Use it to compare refinancing now vs waiting — the single most important number in any refinance decision.
Inputs to check
- Penalty and fees
- Monthly payment savings
- Remaining term
Assumptions
- Breakeven = total upfront costs (penalty + fees) divided by monthly payment savings.
- Assumes savings remain constant for the breakeven period; variable rates change actual outcomes.
- Does not include opportunity cost of cash used to pay penalties and fees upfront.
- Cash-back and rate incentives from new lenders should be subtracted from total costs.

Example scenarios
$12K penalty, $289 monthly savings
Breakeven = $12K / $289 = 41.5 months. If you plan to stay 48+ months, refinancing saves ~$1,900. If you might sell in 2-3 years, the penalty is not recovered.
18 months remaining
With 18 months left and $5K penalty, monthly savings of $175 means breakeven at 28.5 months. Only 18 months of savings = $3,150 — refinancing loses ~$1,850. Wait for penalty-free renewal.
1.50% rate drop — quick breakeven
$400K dropping from 5.75% to 4.25% saves ~$375/month. Even with $15K penalty, breakeven is 40 months. On a 5-year term (60 months), net savings ~$7,500.
Variable penalty advantage
Breaking a variable mortgage costs just 3 months interest — ~$5,031 on $400K at 5.75%. Monthly savings of $289 means breakeven at 17.4 months — far more flexible than fixed.

Frequently asked questions
What if savings are negative or breakeven exceeds my term?
If your payment would increase, refinancing only makes sense if accessing equity for a purpose exceeding the cost. If breakeven exceeds your holding period, refinancing loses money — wait until maturity. The calculator makes this trade-off explicit.
Does breakeven include tax implications?
No. If refinancing to access equity for investment, additional interest may be tax-deductible, improving effective after-tax savings and shortening breakeven. If refinancing triggers a capital gain on investment property, the tax cost extends breakeven.
Should I refinance within 6 months of maturity?
Almost never. A 3-month interest penalty (variable) or IRD penalty (fixed) within 6 months of maturity is nearly impossible to recover through rate savings. Renewal at maturity is penalty-free. Only exception: urgent equity access that cannot wait.
Is cash-back from a new lender considered?
Yes. If a new lender offers $2K cash-back, subtract that from upfront costs. A $12K penalty minus $2K cash-back = $10K net cost, reducing breakeven from 41.5 to 34.6 months. Always factor cash-back and rate buy-down incentives.
