Frequently asked questions

When is it worth it to refinance?

The short answer: when your break-even month (closing costs divided by monthly savings) is shorter than how long you plan to keep the loan. Refinancing to save $200/month on a loan with $6,000 in closing costs breaks even at month 30, so it's worth it only if you'll keep the loan longer than that.

How much of a rate drop justifies refinancing?

The old rule of thumb was a 1% rate drop, but it depends entirely on closing costs and how long you plan to keep the loan. Even a 0.5% drop can be worth it for low-cost refinances or long hold periods. Use the break-even calculation, not a rate-drop threshold.

What closing costs should I expect on a refinance?

Mortgage refinances typically cost 2-5% of the loan amount. On a $400,000 loan, that's $8,000-$20,000 in closing costs. Some lenders offer 'no-closing-cost' refis where fees are rolled into the rate, which can make sense if you're only keeping the loan a few years.

Does refinancing hurt my credit score?

Short-term, yes — a new loan application creates a hard inquiry that drops your score by a few points. Long-term, refinancing has no impact on credit health as long as you continue making on-time payments. The inquiry drop resolves within a few months.

Can I refinance an auto loan?

Yes, and auto refinancing is often easier than mortgage refinancing because closing costs are minimal. If your credit has improved since you bought the car, or if rates have dropped, refinancing can save thousands with minimal effort.

Should I refinance to a shorter loan term?

Refinancing to a shorter term (e.g., 30-year to 15-year mortgage) dramatically reduces total interest but significantly raises the monthly payment. This makes sense if you can comfortably afford the higher payment and plan to stay in the home. Otherwise, you can simulate the effect by making extra payments on a longer-term loan.
