New term	New payment	Monthly savings	Lifetime interest difference	Break-even
30-year	$3,597	$195	$70,238 less	62 months
20-year	$4,299	−$506 (higher)	$333,606 less	n/a (payment rises)
15-year	$5,063	−$1,271 (higher)	$453,902 less	n/a (payment rises)

Is it worth it?

A break-even of 62 months is long. You'd need to keep the loan more than 6 years to come out ahead, so this refinance makes sense mainly if you're settled long-term or can get closing costs well below 2%.

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.
