Is it worth it?
A break-even of 20 months is short. If you expect to keep the loan for at least two years, this refinance is likely to pay for itself, and every month after that is savings — about $25,300 net after five years.
Shorter terms raise the payment but cut lifetime interest sharply. Want the background? Read is it worth refinancing for 1%, or check your own costs with the break-even calculator.
