About this tool

Refinancing a mortgage replaces your existing loan with a new one, usually to get a lower rate — but the closing costs mean it only pays off if you keep the new loan long enough. This calculator compares your current and new terms, showing the monthly payment reduction, the break-even point in months (how long until the savings recoup the closing costs), and the lifetime savings.

The break-even point is the decisive number. A lower rate always looks appealing, but if you sell or refinance again before recouping the upfront costs, you lose money on the deal. Seeing exactly how many months it takes to come out ahead turns refinancing from a gut call into a clear decision.

It runs in your browser, so your loan details stay private. Use it to decide whether refinancing is worthwhile, compare offers, or check how long you would need to stay for a new rate to pay off.

Frequently asked questions

When is refinancing worth it?
When you will keep the new loan long enough for the monthly savings to exceed the closing costs. The break-even point tells you how many months that takes.
What is the refinance break-even point?
The number of months of payment savings needed to recoup the closing costs of the new loan. Stay beyond it and you save money; leave before it and you lose.
Does a lower rate always mean I should refinance?
No. Closing costs can outweigh the savings if you move or refinance again too soon. The calculator weighs the rate reduction against those upfront costs.
Are my loan details private?
Yes. The calculation runs in your browser, so nothing you enter is uploaded.
