Current rates, the break-even calculation, and exactly what you need to know before making the decision.
If you bought or refinanced your home between 2020 and 2022, you're likely sitting on a rate between 2.5% and 4%. If you bought in 2023 or 2024, you may have a rate above 7%. The right answer to "should I refinance?" is completely different for those two groups — and it changes every time rates move.
This guide cuts through the noise. We'll show you the exact math, explain what the 1% rule actually means, and give you a free calculator to run your specific numbers.
After the Federal Reserve's aggressive rate-hiking cycle of 2022–2023 pushed 30-year fixed mortgage rates above 8%, rates have gradually retreated. As of early 2026, the 30-year fixed rate is hovering around 6.5%–7%, with some lenders offering competitive rates to well-qualified borrowers.
What this means in practice: if you have a rate above 7.5%, there's a reasonable case for refinancing now. If you have a rate below 5%, you're almost certainly better off waiting — or not refinancing at all. If you're in between, the math depends entirely on your specific loan balance, closing costs, and how long you plan to stay.
Rates change daily. The figures above are approximate averages. Use the calculator below to see today's numbers applied to your specific loan — that's the only number that actually matters.
Refinancing makes sense when the long-term savings outweigh the upfront cost. That sounds simple, but most people skip the actual math — which is why so many homeowners either refinance too early (and pay closing costs twice) or never refinance at all (and leave thousands on the table).
The core question is not "are rates lower?" It's "how long will it take me to recoup the closing costs, and will I still be in this home by then?"
You have a rate above 7%, plan to stay in your home for at least 3 more years, have 20%+ equity, and a credit score above 740. A 0.75%+ rate drop saves most borrowers $150–$400/month.
You locked in a rate below 4%, you're planning to sell within 2 years, you're near the end of your mortgage term, or you've already paid significant interest (later in a 30-year loan, most of your payment is principal).
The break-even point tells you exactly how long it takes to recoup your closing costs through monthly savings. It's the single most important number in the refinancing decision.
Break-even months = Total closing costs ÷ Monthly savings
Example: $8,000 closing costs ÷ $280/month savings = 28.6 months. If you plan to stay longer than 29 months, refinancing makes financial sense.
Closing costs typically run 2–3% of the loan amount. On a $350,000 loan, that's $7,000–$10,500 out of pocket (or rolled into the new loan). Monthly savings depend on the rate difference and your remaining balance.
| Loan Balance | Rate Drop | Monthly Savings | Break-Even (at $8k costs) |
|---|---|---|---|
| $200,000 | 0.5% | ~$60/mo | 133 months |
| $300,000 | 0.75% | ~$140/mo | 57 months |
| $350,000 | 1.0% | ~$215/mo | 37 months |
| $400,000 | 1.25% | ~$310/mo | 26 months |
| $500,000 | 1.0% | ~$290/mo | 28 months |
The table above illustrates why the 1% rule of thumb doesn't tell the whole story. A 0.5% drop on a $200,000 loan takes 11 years to break even — probably not worth it. The same drop on a $500,000 loan might break even in 2 years.
The "1% rule" says refinancing is worth it if you can lower your rate by at least 1 percentage point. It's been repeated so often it feels like financial law. But it's actually a rough heuristic from an era of lower home prices and smaller loan balances.
In 2026, with the median home price above $400,000 and average loan balances well over $300,000, a 0.5% rate drop can easily generate $150–$200/month in savings — enough to break even in 3–4 years on typical closing costs. That's a perfectly reasonable refinance.
Use it as a quick filter: if your rate drop is less than 0.5%, be skeptical. If it's 1%+, almost certainly worth running the numbers. Everything in between depends on your balance, your closing costs, and how long you're staying.
The more accurate approach is the break-even calculation above — which accounts for your specific balance and closing costs rather than applying a one-size-fits-all threshold.
This is the highest-priority group for 2026. If rates have dropped even 0.75% from your original rate, the math likely works. With a $350,000+ loan, a 0.75% drop saves roughly $170/month. At typical closing costs of $8,000–$10,000, you'd break even in 47–59 months. If you plan to stay 5+ years, refinancing now is worth serious consideration.
Current rates are still higher than what you have. Refinancing would increase your payment. Wait — or run the numbers again if rates drop below 4.5%.
Do not refinance at current rates. Your rate is the envy of the mortgage market. Even a significant future rate drop would likely not beat what you have. Hold your rate like it's an asset — because it is.
This is a valid reason to refinance even if rates are similar. A 15-year loan at 6.1% vs a 30-year at 6.75% saves substantial total interest — though your monthly payment will increase. Run the numbers carefully against your budget.
Cash-out refinancing replaces your mortgage with a larger one and gives you the difference in cash. It can make sense for home improvements or consolidating high-interest debt — but you're taking on more debt secured by your home. Proceed carefully and only if the math is clearly favorable.
Closing costs are the biggest variable in the refinancing decision. Most borrowers are surprised by how much they add up. Here's what to expect:
Some lenders advertise "no-closing-cost" refinancing. In most cases, the costs are simply rolled into a slightly higher interest rate. This can make sense if you plan to sell or refinance again within a few years — just understand the tradeoff.
Closing costs vary significantly by lender. Getting 3+ quotes is the single easiest way to save $2,000–$5,000 on your refinance. The HomeMath refinance calculator lets you compare multiple rate scenarios side by side.
