How do you choose between refinancing and extra payments?

The honest answer is "do the math" — and then check that the math survives reality. A refinance saves money only if the rate drop is large enough that the monthly savings outpaces the closing costs within a few years, AND you actually stay in the home long enough to capture those savings.

What rate drop justifies a refinance?

The classic rule of thumb is at least 0.75-1.0% below your current rate. Below that, closing costs typically eat the savings. The longer your remaining term, the smaller the rate drop needed to make a refi worthwhile.

When are extra payments the smarter move?

Extra payments win when current rates are not meaningfully lower than yours, when you plan to move within 3-5 years, or when you cannot easily come up with $5K-$10K for closing costs. They are zero-cost, fully reversible, and preserve your existing rate.

What if you are refinancing mainly to escape PMI?

Check first whether you can simply cancel it. On a conventional loan, borrower-paid PMI can be removed on request at 80% loan-to-value for little or no cost, which beats a refinance that resets your term and charges closing costs. Refinancing is the right exit only for FHA loans carrying lifetime MIP, or for lender-paid PMI baked into the rate — our guide to removing PMI without refinancing covers which situation you are in.
