Calculate simple break-even—then go deeper
A basic break-even divides net refinance closing costs by monthly savings on the same comparable payment components. That is only a screening tool. It can be misleading if the new loan extends the term, capitalizes costs or changes the principal balance; compare projected interest and remaining balance over the period you expect to own the home.
- Calculate all-in loan costs net of actual credits
- Compare principal and interest on the same basis
- Evaluate remaining loan balance and total interest, not just monthly savings
