Calculate refinance break-even month. Factor closing costs, rate drop, monthly savings. See if refinancing your mortgage pays off in 2026.
Your refinance break-even point is the month when accumulated monthly savings equal the closing costs you paid upfront. The formula is brutally simple: Break-even months = Total closing costs ÷ Monthly payment savings. If your refi costs $6,000 and saves you $250/month, you break even at month 24. Stay in the home past that point and every payment is pure savings. Sell or refi again before that, and you lost money.
That's the entire calculation. But the actual decision is dirtier than the math suggests — closing costs vary 3x between lenders, "monthly savings" hides escrow shifts and lost principal payments, and a 2026 rate environment of 5.5–6.5% on 30-year fixed mortgages means break-even windows are running 28–42 months for most homeowners refinancing from 7%+ rates locked in 2024.
Let's run a 2026 example. You bought in March 2024 with a 7.25% 30-year fixed on a $400,000 loan. Your principal and interest payment is $2,728. Rates have dropped to 5.875% and you're shopping a refi.
The new loan at 5.875% on the same $400,000 balance gives a P&I of $2,367. Monthly savings: $361.
Closing costs on a $400,000 conventional refi typically run 2–4% of the loan amount. Let's say you're quoted $8,400 (2.1%) — lender fees of $1,800, title and escrow $1,900, appraisal $650, recording and government $400, prepaid interest and tax escrow setup $3,650.
Break-even = $8,400 ÷ $361 = 23.3 months.
If you plan to stay past July 2028, the refi pays for itself. If you might sell or move within two years, walk away — you'll lose money on the closing costs.
Generic break-even calculators treat closing costs as a single number. In reality, only two of the three categories should be in your break-even math.
This is where 70% of borrowers miscalculate. Your closing disclosure will list "prepaid interest," "homeowners insurance," and "property tax escrow" — often $3,000–$6,000 combined. These are not refi costs. You would owe these on your existing mortgage anyway. Prepaid interest is just the daily interest from closing to month-end. Escrow funding is money you'd have paid your old lender for insurance and taxes.
When calculating break-even, subtract prepaids from the total closing costs. If your lender quotes $8,400 but $2,400 is prepaids, your true refi cost is $6,000 and break-even shrinks to 16.6 months instead of 23.3.
Here's what break-even calculators almost never show: refinancing resets you to year 1 of amortization. In the early years of any mortgage, most of your payment goes to interest, not principal.
Back to our example. After 24 months on the original 7.25% loan, you'd have paid down roughly $7,400 in principal. After 24 months on a fresh 5.875% loan with the same balance, you pay down about $9,100 in principal. So you actually build equity faster on the new loan in this scenario — but only because the rate drop is large enough to offset the reset.
If you refinance from 6.5% to 6.0% (a small rate drop), you're often building less equity per dollar paid because the amortization reset hurts more than the rate cut helps. The break-even calculator says "month 30" but your actual wealth break-even might be month 60+.
Rule of thumb: refis with rate drops under 0.75% rarely make sense unless you're also shortening the term or eliminating PMI.
Your monthly payment goes up, so simple break-even math returns a negative or infinite number. The right calculation is lifetime interest saved minus closing costs. A $400,000 refi from 30-year at 7.25% to 15-year at 5.25% saves roughly $290,000 in total interest. Closing costs of $8,000 are trivial against that.
You're not really "saving" if you're pulling out $50,000 in equity. The break-even comparison must be against your alternative source of funds. If a HELOC at 9% would cost you more over 5 years than rolling that $50,000 into a 6% refi, the refi wins regardless of payment differential. See our HELOC vs Cash-Out Refinance Calculator 2026 for the head-to-head math.
If you'd built equity past 20% and were stuck paying $180/month PMI on your old loan, the PMI elimination is part of your monthly savings — don't forget to add it. This often slashes break-even by 6–12 months.
"No closing cost" refis don't actually eliminate the cost — they finance it. You pay interest on those costs for 30 years. The effective rate is usually 0.25–0.5% higher than the quoted "no-cost" rate. Calculate break-even using the rate-adjusted version: total interest paid over your expected holding period at the higher rate vs. paying closing costs upfront at the lower rate.
If you're 8 years into a 30-year mortgage and refinancing into a new 30-year, you've added 8 years to your payoff. The monthly payment drop is real, but you're paying interest for longer. Compare against refinancing into a 22-year loan (most lenders allow custom terms) for the apples-to-apples answer. Our Mortgage Payoff Calculator shows how aggressive principal payments offset the reset.
Refinance volume in Q1 2026 is up 340% year-over-year as homeowners who locked at 7%+ in 2023–2024 finally see rates drop below 6%. The Fed funds rate sits at 4.0–4.25% as of May 2026, with the 30-year fixed averaging 5.85% nationally.
The traditional rule was "refi when rates drop 1% below your current rate." That rule was built for a world of $200,000 mortgages. On a $500,000 loan, even a 0.5% drop saves $150+/month and can break-even in under 18 months.
The better 2026 rule:
The math: closing costs scale roughly with loan size, but monthly savings scale linearly with rate drop. Bigger loans = faster break-even at smaller rate drops.
Build this in 10 minutes for any refi decision:
Column G is the real answer. Column E is the marketing answer lenders show you.
The Loan Estimate (LE) you receive within 3 days of applying is legally binding within tolerance bands: 0% tolerance on lender fees, 10% tolerance on services you can shop for, unlimited tolerance only on prepaids and services not on the shopping list. Use this. Get LEs from 3+ lenders on the same day, compare line by line, and force lenders to match the lowest.
Lender credits are real money. A lender offering 5.875% with $0 credits versus 6.125% with $4,000 credit means the higher rate effectively reduces your closing costs by $4,000. Plug both scenarios into your break-even calculator. For short holding periods (under 4 years), the credit-heavy option usually wins. For long-term holders (10+ years), the lower rate wins.
For most borrowers refinancing in 2026, break-even falls between 24 and 42 months. The exact number depends on closing costs (typically $4,000–$10,000) divided by monthly P&I savings (typically $150–$500). Always exclude prepaid interest and escrow funding from the closing cost number — those aren't true refi costs.
Only if your break-even is under 30 months and you're confident in the timeline. Run the worst-case scenario: if you sold the day after closing, you'd lose 100% of closing costs. If you sold at month 24 with a 30-month break-even, you'd lose 20% of closing costs minus realized savings. Lender-credit refis with $0 cash-to-close shift this risk significantly in your favor for short-timeline borrowers.
The "total closing costs" line on your Loan Estimate includes property tax escrow setup and homeowners insurance prepayment, but these are NOT true refinance costs — you'd owe these on your existing mortgage too. For break-even math, subtract prepaids from total closing costs. The remaining number (typically $4,000–$8,000) is your actual refi cost.
No. "No closing cost" means the lender absorbs upfront fees in exchange for charging you a higher interest rate (typically 0.25–0.5% above their lowest rate) or rolling costs into the loan balance. Over a 30-year holding period, no-cost refis usually cost more than paying closing costs upfront. Over a 5-year holding period, they often cost less. Run both scenarios through a break-even calculator with realistic holding-period assumptions.
True refinance costs (excluding prepaids) run 1.5–3% of the loan amount. On a $400,000 refi, expect $6,000–$12,000 in lender fees, title insurance, appraisal, and recording. Conventional loans cost less than FHA or VA refis. Streamline refis (FHA, VA IRRRL) skip appraisals and can run as low as $2,500–$4,000 in true costs.
Temporarily, yes — a hard inquiry typically drops your score 3–7 points, and the new account lowers your average account age. Multiple mortgage inquiries within 14–45 days count as a single inquiry for FICO scoring purposes, so shop aggressively in a tight window. Most borrowers recover their full score within 6 months as the new loan establishes payment history.
