When Should You Refinance?

Refinancing replaces your current mortgage with a new one, usually at a lower interest rate. The key question is whether the monthly savings justify the closing costs. A common rule of thumb: if you can lower your rate by at least 0.75% and plan to stay in the home for 3+ more years, it is probably worth exploring.

Understanding the Break-Even Point

The break-even point is how many months it takes for your monthly savings to cover the closing costs. If closing costs are $6,000 and you save $200/month, break-even is 30 months. If you plan to sell or move before that point, refinancing may cost you more than it saves.

Watch the Total Cost

A lower monthly payment does not always mean you save money overall. If you refinance from a 15-year loan into a new 30-year loan, your payment drops but your total interest over the life of the loan could increase significantly. This calculator shows both monthly savings and total lifetime cost so you can see the full picture.

What are typical closing costs?
Closing costs for a refinance typically run 2-5% of the loan amount. On a $300,000 loan, expect $6,000-$15,000. This includes appraisal fees, title insurance, origination fees, and other lender charges. Some lenders offer "no-closing-cost" refinances, but the cost is usually rolled into a higher interest rate.
Should I refinance into a shorter term?
If you can afford the higher payment, refinancing from a 30-year to a 15-year mortgage can save you tens of thousands in interest. The rate on a 15-year is usually lower too. But make sure the higher payment fits comfortably in your budget.
Does refinancing hurt my credit score?
Applying for a refinance triggers a hard credit inquiry, which may drop your score by a few points temporarily. The new loan also resets your account age. However, if you make payments on time, your score typically recovers within a few months.
