Refinance Break-even Calculator

Is refinancing worth it? This finds the month you truly come out ahead, counting closing costs, points and the interest lost to restarting your loan, and what you gain if you stay. Runs in your browser; we don't store what you enter.

How far ahead (or behind) refinancing leaves you

New term Keep your payoff date Keep paying the old payment Break-even

Running total of how far ahead refinancing leaves you compared with keeping your current loan, month by month, for three ways to take the new loan. Above zero you are ahead. The full figures are in the year-by-year table below.

What could change the answer

Payment, break-even, net gain and lifetime interest for each scenario
Scenario Payment Break-even Ahead when you leave Lifetime interest

"Ahead when you leave" is in today's dollars. Lifetime interest is compared with what's left to pay on your current loan.
