Mortgage refinance analysis calculator. Compares current and new loan interest rates, computing monthly payment reductions, break-even months to recoup closing fees, and lifetime savings.
Runs entirely in your browser
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.
