What is break-even
The single number that tells you if a refinance is actually worth it.
The refinance break-even point is the number of months it takes for your monthly savings from a lower rate to fully offset the closing costs of refinancing. If you sell or pay off the loan before that point, you lose money on the refinance. If you stay longer, every additional month is pure savings. The formula is simple:
Break-Even Months = Closing Costs ÷ Monthly Savings
A homeowner with $6,500 in closing costs and $325 in monthly savings hits break-even at 20 months. If they plan to stay in the home for 5 more years (60 months), the refinance saves them roughly $13,000 net. If they're planning to sell in 18 months, the same refinance costs them money.
This is the most important math in any refinance decision, and it's the math most lenders don't put in front of you upfront.
How to read your number
Your break-even point in context.
The break-even number alone doesn't tell you whether to refinance — you also need to honestly assess how long you plan to keep the loan. Here's how to interpret your result:
| Break-Even Period |
What It Means |
Recommendation |
| Under 24 months |
Strong refinance candidate. Closing costs recovered quickly. |
Likely worth it for most owners |
| 24 to 48 months |
Moderate timeline. Worth it if you'll stay 5+ years. |
Worth a closer look |
| 48 to 72 months |
Long recovery. Only worthwhile for long-term holders. |
Marginal — check no-cost refi options |
| Over 72 months |
Recovery period exceeds typical homeownership span. |
Probably not worth it |
A useful rule of thumb: aim for a break-even point that's at least 50% shorter than how long you plan to stay in the home. If you're certain you'll be there another 8 years, a 36-month break-even leaves 60 months of pure savings on top.
What this calculator can't tell you
When the break-even number alone isn't enough.
Break-even math is the right starting point, but a few situations need a second look beyond the number:
You're rolling closing costs into the loan
If you're not bringing closing costs to closing — instead financing them into the new loan balance — your true break-even shifts because you're now paying interest on those costs over the loan's life. Most refinance offers come with a "no closing cost" option that adjusts the rate upward. Compare both scenarios with your loan officer.
You're shortening your term
Refinancing from a 30-year into a 15-year loan often raises your monthly payment even at a much lower rate — so the calculator will show "negative savings." That doesn't mean it's a bad move. The savings show up as interest you'll never pay, not as monthly cash flow. For shorter-term refinances, focus on lifetime interest saved rather than the break-even month count.
You're tapping equity (cash-out refinance)
A cash-out refinance isn't really a rate-improvement decision — it's a borrowing decision. The break-even calculation gets distorted when the new loan is significantly larger than the old one. If your primary goal is accessing cash, evaluate it against a HELOC or home equity loan instead.
You're avoiding PMI
If you currently pay private mortgage insurance and a refinance will eliminate it (because your home value has risen and you now have 20%+ equity), the PMI savings should be added to your monthly savings figure — not just the interest difference. This often dramatically shortens the break-even period.
Regional context
What break-even looks like in New England.
Refinance math is universal, but the inputs vary by where you live. A few patterns we see across NextGen's footprint:
New Hampshire and Massachusetts homeowners often have larger loan balances than the national median, which means even modest rate drops produce meaningful monthly savings. A 0.75% rate improvement on a $400,000 NH loan saves roughly $200/month, recovering $6,500 in closing costs in about 33 months.
Maine and Rhode Island homeowners tend to have smaller loan balances and longer planned tenures, which usually pushes break-even further out but extends the long-term savings window. A 25-year horizon is common.
Florida homeowners who refinanced during 2020–2022 are typically in the strongest position to refinance again only if rates drop meaningfully — the bar is higher because their starting rate was already low.
The math doesn't change by state, but the strategy does. A NextGen loan officer can walk you through both your specific numbers and the broader market context for whether now is the right moment.
