How the Refinance Break Even Clock Works
Refinancing a mortgage involves trading higher closing costs today for lower monthly payments tomorrow. The break even clock tells you how many months it takes for the monthly savings to accumulate enough to cover those closing costs. If you plan to stay in the home beyond the break even point, refinancing makes financial sense. A 3000 closing cost with 150 monthly savings breaks even in 20 months. Rate reduction of zero point seven five percent often cited as rule of thumb yet costs dominate small loans. Cash out refinance raises balance; break even on payment savings alone ignores larger principal owed.
This calculator compares your current mortgage payment against the new payment at a lower rate. It computes the monthly savings, the number of months to break even, and the total interest saved over the remaining loan term. All three numbers are essential for an informed refinance decision. Total interest saved shows lifetime benefit after recovering closing costs, not just the monthly payment drop. Cash out refinance raises balance; break even on payment savings alone ignores larger principal owed. Four thousand closing costs divided by one hundred ninety monthly savings breaks even near twenty one months. Resetting thirty year term lowers payment but may increase lifetime interest versus keeping remaining term.

Refinance Break Even Formula
Old Payment = Balance x (Old Rate / 12) / (1 - (1 + Old Rate / 12)^(-Remaining Months))
New Payment = Balance x (New Rate / 12) / (1 - (1 + New Rate / 12)^(-Remaining Months))
Monthly Savings = Old Payment - New Payment
Break Even Months = Closing Costs / Monthly Savings
Total Interest Saved = (Old Total Interest - New Total Interest) - Closing Costs
