Common questions
What is a balance transfer?
A balance transfer moves your existing credit card debt to a new card with a lower (often 0%) introductory interest rate. You typically pay a one-time transfer fee of 1-3% of the balance.
Are balance transfers worth it?
They can save you hundreds in interest if you pay off the balance during the introductory period. But if you don't pay it off before the revert rate kicks in, the savings may be less than expected.
What happens when the intro period ends?
The interest rate reverts to the card's standard purchase rate (often 19-22%). Any remaining balance starts accruing interest at this higher rate.
