What is a balance transfer?

A balance transfer moves existing credit card debt onto a new card offering a low or 0% introductory rate for a set period. It’s a tool to pay down debt faster by pausing interest. Used well, more of each repayment goes to the principal rather than to the lender.

How introductory rates and revert rates work

The headline is the introductory rate (often 0%) and its length (commonly 6 to 24 months, with a few offers running longer). What matters just as much is the revert rate, the rate any remaining balance jumps to when the intro period ends, which is often high. Any balance cleared before the offer expires avoids it.

The balance transfer fee and timing

Many offers charge a one-off balance transfer fee (a percentage of the amount moved), which can offset the interest saved. New purchases on a balance-transfer card often don’t get the intro rate and can attract interest immediately, so spending on the card slows the transfer and adds interest.

How balance transfer offers compare

The intro rate and length, the transfer fee, the revert rate and whether purchases are covered are the figures that separate them. Cards can be compared side by side, alongside low rate cards and the credit cards hub.
