The method, explained

Compute both amortizing monthly payments on the same balance. Monthly saving = old payment − new payment. Simple cash-flow break-even = upfront costs / positive monthly saving. Compare total remaining payments, including new costs, separately.

A WORKED EXAMPLE

Using current outstanding balance = 200000 money, current annual interest rate = 7 %, remaining months = 240, new annual interest rate = 5 %, new term in months = 240, upfront refinancing costs = 4000 money, the result is 230.686393 currency. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

No cash-out or financed closing costs. The simple break-even ignores differing balances, tax effects and opportunity cost. It is not an economic recommendation. A scenario calculation using your inputs, before unlisted fees or taxes. It is not a quoted product rate or personalized recommendation.
