The classic rule "refinance if you can drop your rate by 1%" is too simple. The correct question is: how long until the monthly savings exceed the closing costs? That break-even analysis determines whether refinancing makes sense.
The break-even calculation

No-cost refinancing: the hidden trade-off
Lenders sometimes offer "no-cost" refinancing where closing costs are rolled into the loan balance or you accept a slightly higher rate. The trade-off: higher loan balance or higher rate vs no upfront cash. Run the break-even on both scenarios. No-cost makes sense if you might move in 3–5 years.
Cash-out refinancing: think twice
Cash-out refinancing replaces your mortgage with a larger one, giving you the difference as cash. With 6–7% rates in 2026: you're taking on debt at 6–7% to get cash. Compare against: HELOC (similar rate, more flexible), personal loan (higher rate but smaller impact on primary mortgage), or simply not spending. Cash-out also resets your amortization clock.
