Balance transfers are rarely “free.” The credit card issuer will almost always charge a ‘balance transfer fee’ of around 3% to 5% on the total amount of debt that you transfer. Besides credit card debt, some balance transfer cards will let you move other forms of debt onto the card, like auto and personal loans. After opening the balance transfer card, you’ll have an extended period of time, usually up to 18 or even 21 months, when no interest will be charged. This way, you can more effectively pay off credit card debt. How do balance transfer cards work? Balance transfer cards work by sending debt from one card account to another, so you can more easily pay down balances by avoiding interest. For example, you may have $5,000 in debt on one credit with an APR of 18%. A balance transfer card would allow you to transfer this debt to it, offering a 0% APR for a certain amount of time. When making a balance transfer, cardholders will be charged a fee that is added to their overall balance. Bills must still be paid on the old credit account until the balance transfer is completed. How long does a balance transfer take? Typically a balance transfer takes around five to seven days, but it can take even longer — two to three weeks (opens in new tab) in some cases — it really depends on the card. How should you choose a balance transfer card? What you’ll need to consider when choosing a balance transfer card. How long of an introductory APR period do you need?

If you’re unsure whether you’ll be able to pay down balances in full in the time frame, this rate is especially important. Make sure you take into account the balance transfer fee associated with the card as well, which can add anywhere from 3% to 5% on top of existing debt.After that, you’ll want to review your credit score and credit report, something important to do before applying for any credit card.
