Refinance Calculator

A refinance is worth it when you keep the loan long enough to recover the cost. That's the whole analysis, and it's why 'is the rate low enough?' is the wrong question.

This calculator compares your current payment to the new one and tells you the month you break even, including the interest you reset by starting a new term.

What happens if you change this

You'd save $271 a month and recover $4,500 in costs after about 16.6 months. If you expect to stay longer than that, the refinance pays for itself. And because the new term isn't stretching things out, you also save $29,901 in total interest.

Questions people ask

How much lower does the rate need to be?
There's no magic number. What matters is the break-even month versus how long you'll keep the loan. A small rate drop on a large balance can beat a big drop on a small one.
Does refinancing restart my loan?
It starts a new term, which is why a lower payment can still mean more total interest. Choosing a shorter new term avoids that.
