A balance transfer moves debt from one credit card to another, usually to a card offering a lower interest rate for a set period

When you do a balance transfer, you ask a new credit card company to pay off the balance you owe on an old card. The debt moves to the new card, but you still owe the money — you are not erasing it. The main reason people do this is to move debt to a card with a lower or zero interest rate, which can save money if you pay down the balance before that promotional rate ends.

Balance transfers are not the same as a cash advance or a new purchase. The credit card company treats the transferred balance as its own category, with its own interest rate and its own payment terms. This matters because the way you pay affects which balance gets paid first.

Key Takeaways

  • A balance transfer moves your existing debt to a new card, usually one with a lower introductory interest rate that lasts anywhere from three months to two years.
  • Most balance transfer cards charge a fee upfront — typically 3 to 5 percent of the amount transferred — which gets added to what you owe.
  • After the promotional rate ends, the regular interest rate kicks in, so you need a plan to pay down the balance before that happens.
  • Payments go toward the balance with the highest interest rate first, so new purchases on the card may sit unpaid while you cover the transferred balance.

How the balance transfer process works

You start by opening a new credit card that offers a balance transfer promotion. During your application, you provide the name of your old card issuer, your old account number, and the amount you want to transfer. The new card company contacts your old issuer and arranges the payment directly — you do not send money yourself.

The transfer usually takes 5 to 14 business days to complete. During that time, you still owe money to your old card issuer, so keep making minimum payments on the old card until the transfer shows up on your new card statement. Once the transfer posts, the balance appears on your new card and the old card balance drops to zero.

You can transfer balances from multiple cards to one new card, but the total cannot exceed your new card's credit limit. Some cards let you transfer balances from store cards, medical credit lines, and personal loans — not just other credit cards — so check the card's terms before you apply.

Balance transfer fees and what they mean for your savings

Nearly all balance transfer cards charge an upfront fee, usually 3 to 5 percent of the amount you transfer. If you transfer $5,000, you might pay $150 to $250 in fees. This fee gets added to your new card balance, so you owe more than you started with. A few cards offer zero-fee transfers, but these are rare and usually come with shorter promotional periods or higher regular interest rates.

To know whether a balance transfer saves you money, you need to compare three things: the fee, the promotional interest rate, and how long the promotion lasts. If you transfer $5,000 with a 4 percent fee ($200) to a card offering 0 percent for 12 months, you pay $200 upfront but save the interest you would have paid on the old card. If your old card charged 20 percent interest, you would have paid about $1,000 in interest over a year — so the transfer saves you roughly $800 even after the fee. But if you only pay $100 per month toward the balance, you will still owe $4,800 when the promotional rate ends, and then interest starts accruing at the new card's regular rate.

Promotional periods and what happens when they end

Balance transfer promotions typically last between 3 and 21 months, depending on the card. During this time, you pay 0 percent interest on the transferred balance. The card company is betting you will not pay off the full balance before the promotion ends, so they can charge you interest later at a much higher rate.

When the promotional period ends, the regular purchase APR (annual percentage rate) takes over. This rate varies by card and by your creditworthiness, but it often ranges from 15 to 25 percent. If you still owe $3,000 when the promotion ends, you will start paying interest on that $3,000 at the new rate. This is why the math only works if you have a realistic plan to pay down the balance before the promotion expires.

Some cards offer a lower regular APR on transferred balances after the promotion ends, rather than jumping to the full purchase rate. Read the card's terms carefully to see what rate applies after the promotional period — this information is usually in the fine print or in the card's pricing guide.

How payments are applied when you have multiple balances

If your new card has both a transferred balance and new purchases, the card company applies your payment to the balance with the highest interest rate first. During the promotional period, the transferred balance has 0 percent interest and new purchases have the regular rate (usually 15 to 25 percent), so your payment goes toward the new purchases first. This means the transferred balance can sit unpaid while you cover interest on new charges.

To avoid this trap, do not make new purchases on a balance transfer card while you are paying down the transferred balance. If you must use the card, pay more than the minimum so you cover both the new purchases and make progress on the transferred balance. Some people open the balance transfer card, move the balance, and then stop using the card entirely until the transferred balance is paid off.

When a balance transfer makes sense and when it does not

A balance transfer works best if you have a specific plan to pay down the debt before the promotional rate ends, and if the interest you save exceeds the transfer fee. It also works better if your old card charges a much higher interest rate than the promotional rate on the new card — the bigger the gap, the more you save.

A balance transfer does not make sense if you cannot pay down the balance during the promotional period, because you will end up owing more after interest kicks in. It also does not make sense if you have only a small balance, because the transfer fee might cost more than the interest you would pay on the old card. And if you are likely to run up new debt on the new card, a balance transfer just moves the problem rather than solving it.

Balance transfers also affect your credit score in the short term. Opening a new card lowers your average account age and creates a hard inquiry, both of which can drop your score by a few points. Closing your old card after the transfer can also hurt your score by reducing your total available credit. These effects usually fade within a few months, but they are worth knowing about if you are planning to apply for a mortgage or loan soon.

Frequently Asked Questions

Can I transfer a balance if I have bad credit?

Most balance transfer cards require good to excellent credit, usually a score of 670 or higher. If your score is lower, you may not be approved, or you may be approved with a higher regular interest rate. Some cards designed for people rebuilding credit do not offer balance transfer options at all.

What happens if I do not pay off the balance before the promotion ends?

The regular interest rate takes over, and you start paying interest on whatever balance remains. If you owe $2,000 when the promotion ends and the regular rate is 20 percent, you will pay roughly $33 per month in interest alone. You can still pay it off, but it will cost more and take longer.

Can I transfer a balance from a card issued by the same company?

No. You cannot transfer a balance to a card from the same issuer. For example, if you have a Chase card, you cannot transfer that balance to another Chase card. You must transfer to a card from a different company.

Does a balance transfer hurt my credit score?

Yes, but usually only temporarily. Opening a new card creates a hard inquiry and lowers your average account age, which can drop your score by a few points. Your score typically recovers within a few months as you build a payment history on the new card.

What if the transfer does not go through?

If the transfer is declined or incomplete, contact the new card company to find out why. Common reasons include exceeding your credit limit, the old card issuer refusing the transfer, or an error in the account information you provided. You can usually request the transfer again or try a different amount.
