Refinancing can cut your monthly mortgage payment, but you pay for those savings upfront. Whether a refinance actually pays off comes down to one number: your break-even point. That’s the month when your savings finally cover what you paid in closing costs.
October 20, 2026
That math matters most when refinancing picks up. In the first quarter of 2026, total mortgage originations rose 26.0% year over year to 1.24 million, driven largely by refinancing, according to TransUnion’s Q2 2026 Credit Industry Insights Report. Rate-and-term refinances alone rose more than 223%.
Whatever rates are doing when you read this, the calculation is the same and takes only a few minutes. Here’s how to run it before you sign anything.
Your break-even point is how many months it takes for the savings from your new, lower payment to add up to more than you paid in closing costs. Before that point, the refinance has cost you more than it has saved. After it, every month you stay in the home and keep the new loan puts you further ahead.
Find your current monthly principal and interest payment. It’s on your mortgage statement. Leave out taxes and insurance, since those don’t change when you refinance.
Get your new principal and interest payment from a Loan Estimate. Lenders must send one within three business days of your application. Get quotes from several lenders so you’re working with realistic numbers. You can compare mortgage refinance rates from BestMoney side by side.
Subtract to get your monthly savings.
Add up your closing costs from the Loan Estimate (see below for what to include).
Divide closing costs by monthly savings. The result is your break-even point in months.
Worked example (hypothetical numbers):
Original loan: $365,000, 30-year fixed at 7.5%, taken out three years ago
Remaining balance: about $354,000
Current monthly principal and interest: about $2,552
New loan: about $354,000, 30-year fixed at 6.5%
New monthly principal and interest: about $2,238
Monthly savings: about $314
Closing costs at 4% of the new loan: about $14,160
Break-even point = $14,160 ÷ $314 ≈ 45 months, or just under four years
This homeowner would need to keep the new loan for about four years before the refinance pays for itself. If they expect to sell or move before then, the lower rate probably isn’t worth the upfront cost.
Expert Tip: Get quotes from both direct lenders and mortgage brokers. A direct lender offers only its own loans, while a broker can shop your application with several lenders. When I refinanced, a broker got me the best rate and terms. When I bought my next home, a direct lender had the better deal.
[Refinance closing costs] generally run 3% to 6% of your loan principal, according to Freddie Mac. They include the appraisal, credit report, origination, underwriting, title services and government recording fees. On a $354,000 loan, that’s roughly $10,600 to $21,200. The range is wide enough that you should use the figures on your Loan Estimate instead of assuming the low end.
Leave prepaid items out of the math. Your Loan Estimate and Closing Disclosure will also list prepaid homeowners insurance, prepaid interest and an initial escrow deposit. You’d pay these whether or not you refinanced, and your old lender refunds your existing escrow balance after the payoff. Including them makes your break-even point look later than it really is.
Here’s how the cost range changes the timeline, using the same $314 in monthly savings:
Closing costs | Amount | Months to break even |
3% of loan | ~$10,600 | ~34 months (2.8 years) |
4% of loan | ~$14,160 | ~45 months (3.8 years) |
5% of loan | ~$17,700 | ~56 months (4.7 years) |
6% of loan | ~$21,250 | ~68 months (5.6 years) |
If you buy [mortgage points] to lower your rate, add their cost to your closing costs. Points pay off only if you keep the loan well past your break-even point.
What about “no-cost” refinances? The Consumer Financial Protection Bureau notes that these loans still have costs. The lender either charges a higher interest rate or adds the costs to your loan balance, which means larger payments and less equity. Skipping upfront costs gives you an instant break-even on paper, but it can cost more over the life of the loan, so run both scenarios.
Most people build their break-even math around the rate drop alone and forget mortgage insurance moves too, especially on FHA loans where you’re paying that upfront premium a second time. Our own refinance study found that gap can add a full year or more to what looked like a solid three-year payoff. Then if you add in whether you’re rolling closing costs into the loan or paying them out of pocket, and the ‘quick’ break-even often isn’t as quick as the calculator says.
The basic formula compares monthly payments only. If you’ve been paying your current loan for a few years and refinance into a new 30-year mortgage, you restart the clock. You’ll get a lower payment, but you could pay interest for years longer.
Here’s the same homeowner, comparing three options:
Option | Monthly P&I | Monthly savings | Simple break-even | Total interest remaining | Net savings after closing costs |
Keep current loan (27 years left) | $2,552 | — | — | ~$472,800 | — |
Refinance to a 30-year at 6.5% | $2,238 | $314 | ~45 months | ~$451,600 | ~$7,000 |
Refinance to a 27-year at 6.5% | $2,321 | $231 | ~61 months | ~$398,000 | ~$60,600 |
The 30-year refinance has the fastest break-even by the simple formula, but over the full term it saves only about $7,000 after closing costs, because it adds three years of payments. Keeping the original payoff date takes longer to break even by payment, but it saves about $60,600.
For a more accurate break-even, track the interest you save each month instead of the payment difference. By that measure, the 27-year option breaks even in about 48 months and the 30-year in about 50. Many online calculators don’t show this, so ask your lender for an amortization schedule for each option.
You need to stay at least until your break-even point, and the longer you stay after it, the more you save. Three factors move that point:
The size of your rate drop: A common rule of thumb from Freddie Mac says refinancing may make sense when you can lower your rate by about 1 percentage point. Use it as a first filter, not a rule. A 1-point drop on a small balance may save very little, while a smaller drop on a large balance could still be worth it.
Your credit score: Improving your score before you apply may qualify you for a lower rate and a shorter break-even timeline.
Points and fees: Paying more upfront for a lower rate pushes your break-even point later.
Then compare your break-even point with how long you expect to stay:
If you plan to... | Refinancing is... |
Stay well past your break-even point | Likely worth pursuing |
Move before it (for a job change, a growing family or retirement) | Probably not worth it, since the upfront costs won’t have time to pay for themselves |
Stay, but you’re unsure for how long | Worth considering a no-closing-cost or lower-fee option to reduce the risk |
From My Experience: When we refinanced our Florida home in 2021, our closing costs came to $11,095 on a $181,500 loan. That included $5,370 for a year of homeowners insurance premiums plus escrow, and $1,647 in state taxes. [Homeowners insurance] usually costs much less in states with lower hurricane risk, and Florida is one of a handful of states that tax mortgages, including refinances.
Based on our monthly savings, we expected to break even in about four years and were confident we’d stay at least that long.
Then we had a baby, and the house and its location no longer suited our family. We moved two and a half years after refinancing, before we’d earned back those costs, so the refinance ended up as a financial loss.
You can’t predict every change. Make the best decision you can with the information you have, and build in some cushion if your plans could shift.
If your break-even math doesn’t work, these options can still lower your housing costs or give you access to your equity:
A no-closing-cost refinance: This may be the best fit for a short stay. You take a higher rate but pay nothing upfront, so you start saving right away.
A streamline refinance, or refinancing with your current lender: FHA Streamline and VA IRRRL loans usually have lower costs and less paperwork, which shortens the break-even point. Some lenders also cut fees for existing borrowers.
A loan recast: If you have extra cash, some lenders will let you make a lump-sum payment toward principal and recalculate your monthly payment at your current rate, typically for a few hundred dollars. Recasts usually aren’t available on FHA or [VA loans].
Lower escrow costs: Shop for cheaper homeowners insurance or appeal your property tax assessment.
Drop your PMI: On a conventional loan, [private mortgage insurance] ends automatically once your balance is scheduled to reach 78% of your home’s original value. You can ask your lender to cancel it once you reach 80%. If your home has gained value, some lenders will cancel it sooner based on a new appraisal.
If you were planning a cash-out refinance, a home equity loan or HELOC lets you borrow against your equity while keeping your current mortgage rate.
What is a good break-even point on a refinance? That depends on how long you’ll keep the loan. A break-even point you’ll pass with years to spare is a good one. Many homeowners aim for two to three years, but a five-year break-even can still make sense if you plan to stay 15 years.
Should I include mortgage points in my break-even calculation? Yes. Points are an upfront cost, so add them to your closing costs before you divide.
Does refinancing into a new 30-year loan reset my break-even math? It doesn’t change the formula, but it can make the result misleading. Compare total interest over the time you plan to stay, not just the monthly payment.
