How the refinance break-even works
The calculator estimates the current monthly payment and the new monthly payment over the same remaining term. It divides upfront refinance fees by the monthly saving to estimate the break-even month.
What this does not include
Real refinance offers can include prepayment penalties, insurance changes, taxes, broker fees and variable-rate clauses. Treat the result as a screening tool, not personal advice.
Plain-language notes
Use this section if the finance words on the page are new to you. The calculator is meant to support a decision, not to reward perfect terminology.
-
Refinancing: replacing an old loan with a new one. It only helps if savings beat fees and you keep the loan long enough.
-
APR/interest rate: the yearly cost of borrowing. A higher rate usually makes debt more expensive and payoff slower.
-
Principal: the original debt or mortgage balance before interest is added.
What to compare
Compare at least two scenarios before trusting the first answer. A useful result should tell you what changes if income, costs, rates, or timing move.
