When does refinancing a mortgage make sense?

Generally when the new rate is low enough that your monthly savings recover the closing costs before you plan to sell or refinance again. The break-even month in this tool is the key number to watch.

What is the break-even point on a refinance?

It is how many months of payment savings it takes to recoup your closing costs. If you keep the home past that point the refinance starts saving money; if not, it may cost you.

Does refinancing reset my loan term?

Usually yes — a new 30-year loan restarts the clock, which can lower the payment but increase total interest. Comparing a shorter new term can keep more of the savings.

How this tool works

Enter your current mortgage balance, rate, and months remaining, then the new rate, term, and closing costs of a refinance offer. The tool estimates your new payment, the monthly difference, the break-even point on closing costs, and the long-term cost difference.

Why it matters for your credit

A lower interest rate is only half the refinance decision — closing costs and a reset term can erase the savings if you move or sell before you break even. Knowing your break-even month tells you whether a refinance actually pays off for your situation.
