How to compare a refinance

A lower rate does not always guarantee lower total cost. The new loan term and closing costs also matter.

Break-even months = Closing costs ÷ Monthly payment savings

This estimate compares principal and interest only. Taxes, insurance, mortgage insurance and adjustable-rate changes are not included.
