Refinancing makes sense when the monthly savings from a lower rate pay back the closing costs before you sell or move. That single sentence is the entire framework — everything else is detail. As of the week ending May 21, 2026, Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed at 6.51%, with the 15-year at 5.85%. If your current mortgage rate sits at 7.25% or higher, a refinance is almost certainly worth running the numbers on. If you're already below 6%, the math rarely works in 2026. This guide walks through the break-even calculation, the closing-cost ranges to expect, and how to apply the 0.75% rule of thumb without getting burned by edge cases.

The Break-Even Formula
The break-even point is the only number that matters when deciding whether refinancing makes sense. It tells you how many months you need to keep the new loan before the rate savings cover the closing costs.
Break-Even (months) = Closing Costs ÷ Monthly Payment Savings
A borrower paying $6,000 in closing costs who saves $200 a month breaks even at 30 months. If they stay in the home past month 30, every additional month of savings is pure profit. If they sell at month 24, they have lost money on the refinance.
Chase, Bank of America, and most mortgage lenders prefer to see a break-even point under 36 months. Below that, the refinance is generally worthwhile for any borrower who plans to stay put. Above 60 months, the case gets weak — life intervenes, and many homeowners move or refinance again before they collect on the savings.
The 0.75% Rule of Thumb
The classic refinance rule of thumb: refinance if you can drop your rate by at least 0.75 percentage points. At that level, the break-even typically comes in under three years on a 30-year loan — within the window most financial planners recommend. A full 1-point reduction usually pays back closing costs in under two years.
| Rate Drop | Monthly Savings (on $300k loan) | Break-Even at $6,000 Closing | Verdict |
|---|---|---|---|
| 0.25% | ~$48 | 125 months (10.4 years) | Skip |
| 0.50% | ~$98 | 61 months (5.1 years) | Borderline |
| 0.75% | ~$148 | 41 months (3.4 years) | Likely worth it |
| 1.00% | ~$199 | 30 months (2.5 years) | Strong refinance |
| 1.50% | ~$302 | 20 months (1.7 years) | No-brainer |
Monthly savings calculated for a $300,000 30-year loan at 7.25% baseline. Actual savings depend on your loan amount, remaining term, and the new rate.
The 0.75% rule is a starting filter, not a verdict. A jumbo-loan borrower might break even at a 0.4% drop because their loan is large enough that small rate differences move serious dollars. A borrower with five years left on their mortgage might never break even on any refinance because there isn't enough term left to amortize the closing costs.
2026 Refinance Closing Costs — What to Expect
Refinance closing costs in 2026 typically run 2% to 6% of the loan amount, per Freddie Mac and Fortune. On a $300,000 refinance, that range is $6,000 to $18,000. The wide span exists because closing costs are a basket of charges, not a single fee — some lender-driven, some local, some prepaid expenses.
| Fee Category | Typical Range | Notes |
|---|---|---|
| Loan origination fee | 0.5% – 1.5% of loan | The lender's processing fee. Most negotiable item. |
| Appraisal | $500 – $700 | Required unless lender offers an appraisal waiver. |
| Title search & insurance | $400 – $1,500 | Varies widely by state. Often the largest single line item. |
| Credit report | $30 – $60 | Standard. Not negotiable. |
| Recording & transfer taxes | $150 – $1,500+ | State and county dependent. Some states are very expensive. |
| Discount points (optional) | 1% of loan per point | Buys down the rate. Worth it only if the break-even still works. |
| Prepaid escrow + interest | 1 – 3 months of payments | Refundable. Mostly a cash-flow timing issue. |
Freddie Mac estimates average refinance closing costs around $5,000. Industry data from ICE Mortgage Technology shows borrowers who compare quotes from three or more lenders save an average of $1,500 — meaningful money for thirty minutes of work.

When Refinancing Makes Sense Beyond Rate Savings
Pure rate-and-term refinances are not the only reason to refinance. Three other scenarios can justify the cost even when the rate barely moves.
Drop FHA mortgage insurance
FHA MIP runs for the life of the loan. If you have 20%+ equity, refinancing into a conventional loan eliminates the monthly premium even at a flat rate.
Shorten the term
Moving from a 30-year to a 15-year typically costs about $300–$500 more per month but cuts total interest paid in half. Useful when income has grown.
Tap home equity
A cash-out refinance can replace higher-rate debt with mortgage-rate debt. Math only works if the rate drop on the cashed-out portion is meaningful.
The trap to avoid is refinancing for cosmetic reasons — a slightly different lender, a fresh 30-year term that resets your amortization, or a "low rate" achieved by paying excessive points. Run the break-even before signing anything.
Worked Example: Refinancing a 7.5% Mortgage in 2026
A homeowner closed on a $350,000 30-year mortgage in late 2023 at 7.5%. Their current principal and interest payment is roughly $2,447 per month. As of May 2026, a 30-year fixed-rate refinance is available at 6.51% (Freddie Mac PMMS). Closing costs come in at $7,500.
| Item | Before Refi | After Refi |
|---|---|---|
| Loan balance (approx.) | $343,000 | $343,000 |
| Interest rate | 7.50% | 6.51% |
| Monthly principal & interest | ~$2,447 | ~$2,173 |
| Monthly savings | $274 |
Break-even = $7,500 ÷ $274 = 27.4 months. If this homeowner plans to stay in the home longer than about 28 months, the refinance pays for itself. Over a remaining 27-year term, the total interest savings are substantial — well over $90,000 if the loan is carried to maturity.

Frequently Asked Questions
When does refinancing a mortgage make sense?
Refinancing typically makes sense when you can lower your interest rate by at least 0.75 percentage points, your break-even point on closing costs is under 36 months, and you plan to stay in the home past that break-even. As of May 2026 with the 30-year fixed at 6.51%, a borrower with a 7.5%+ existing loan can almost always benefit, while a borrower already at 6.5% should wait.
How do I calculate the refinance break-even point?
Divide your total closing costs by your monthly payment savings. If closing costs are $6,000 and refinancing cuts your payment by $200 per month, your break-even is 30 months. You need to keep the loan past that point to come out ahead. Use a refinance savings calculator to model the exact number for your loan.
What are average refinance closing costs in 2026?
Refinance closing costs typically run 2% to 6% of the loan amount in 2026, according to Freddie Mac and Fortune. On a $300,000 refinance that's $6,000 to $18,000. Freddie Mac estimates the average is around $5,000. Comparison shopping three or more lenders saves an average of $1,500, per ICE Mortgage Technology.
Is a no-closing-cost refinance worth it?
No-closing-cost refinances are not free — the lender either rolls the costs into the loan balance or charges a higher interest rate. They make sense if you plan to sell or refinance again within a few years, since you avoid paying costs up front. For borrowers staying long-term, paying closing costs at closing and getting a lower rate usually wins.
Will mortgage refinance rates drop in 2026?
As of May 21, 2026, Freddie Mac's PMMS reports the 30-year fixed at 6.51%. Fannie Mae expects the rate to end 2026 near 5.9%; the Mortgage Bankers Association forecasts roughly 6.4%; NAR is in between near 6.0%. None of the major forecasters expect a return to sub-5% rates in 2026.
Does refinancing hurt my credit score?
The hard credit pull from a refinance application drops your score by 5–10 points temporarily. Multiple mortgage inquiries within a 45-day rate-shopping window count as one inquiry for FICO scoring purposes, so comparing lenders does not multiply the hit. Scores typically recover within a few months of closing.
