How it works

A balance transfer moves your existing debt to a new card with a low or 0% intro APR. The catch is a one-time transfer fee (usually 3–5%) and a deadline — if you don't pay off the balance before the promo period ends, interest kicks in on whatever remains.

Is it worth it?

Subtract the transfer fee from the interest you'd otherwise pay. If that number is positive, the transfer saves you money. The calculator does this automatically.
