How this is calculated

We compute new payment from the new principal, new APR, and new term. Breakeven = upfront fees ÷ monthly savings. We also report the total interest difference so you can spot term-reset traps.

Frequently asked questions

Should I roll fees into my new loan?
Rolling fees in spreads the cost across payments but increases the financed balance and total interest.
What is the breakeven month?
Breakeven is upfront fees divided by monthly savings — the month at which your savings exceed the cost of refinancing.
