What a balance transfer is and when to use one

A balance transfer moves debt you owe on one credit card to a different credit card, usually one with a lower interest rate. You do not pay off the debt — you move it. The new card's issuer pays off your old card's balance, and you then owe that new card instead.

Balance transfers are most useful when you carry a balance on a high-interest card and a new card offers a lower rate, especially a promotional rate of 0% for a set period (often 6 to 21 months, depending on the card). During that period, your payment goes entirely toward the principal instead of interest, so you can pay down the debt faster.

They are less useful if you plan to carry the balance beyond the promotional period, because the regular interest rate on the new card may be similar to what you already pay. They also do not help if you keep using the old card after the transfer — you will straightforward accumulate new debt elsewhere.

Key Takeaways

  • A balance transfer moves your existing credit card debt to a new card, usually to take advantage of a lower or 0% promotional interest rate.
  • Most balance transfer cards charge a one-time fee (typically 3% to 5% of the amount transferred) that is added to your new balance.
  • The promotional 0% rate applies only to the transferred balance, not to new purchases you make on the new card.
  • You must request the balance transfer when you open the new card or shortly after, because the promotional period begins when the transfer posts, not when you open the account.
  • Paying down the transferred balance before the promotional period ends is critical — after it expires, the regular interest rate kicks in on any remaining balance.

How to request a balance transfer from your new card issuer

Once you open a new credit card account, contact the card issuer to request the balance transfer. Most issuers let you do this online through your account portal, by phone, or sometimes through their mobile app. You will need the account number of the card you want to transfer from, the balance you want to move, and the name and address of that card's issuer.

The new card's issuer will contact your old card's issuer directly to arrange payment. You do not send money yourself. The transfer typically posts within 5 to 14 business days, though some issuers are faster. During this time, keep making at least the minimum payment on your old card to avoid late fees — the transfer has not yet arrived.

Once the transfer posts, your old card's balance will drop to zero (or to whatever new charges you made after requesting the transfer). Your new card's balance will reflect the transferred amount plus the balance transfer fee.

Understanding balance transfer fees and how they work

Nearly all balance transfer cards charge a balance transfer fee, a one-time percentage of the amount you transfer. This fee is typically 3% to 5%, though some cards charge as little as 1% or as much as 5%. A few cards offer 0% transfer fees for a limited time, usually as a promotional offer.

The fee is not charged separately — it is added directly to your new balance. If you transfer $5,000 with a 3% fee, you will owe $5,150 on the new card. This means the fee is subject to the card's interest rate once the promotional period ends, so it matters whether you pay down the balance before that happens.

To decide whether a balance transfer makes sense, compare the fee against the interest you would pay on your old card during the promotional period. If you owe $5,000 at 20% interest and would take 12 months to pay it off, you would pay roughly $1,000 in interest. A 3% transfer fee ($150) plus 0% interest during those 12 months is a much better deal. But if you only owe $500 and plan to pay it off in two months, the fee might cost more than the interest you would save.

What happens to your old card after the transfer

Your old card does not close automatically when you transfer the balance. The account remains open with a zero balance. You can close it yourself if you want, but many people leave it open because closing a card can slightly lower your credit score (it reduces the total credit available to you).

If you leave the old card open, do not use it. Any new charges you make will accrue interest at the old card's regular rate, and you will end up with debt on two cards again. Some people freeze or lock the card to prevent accidental use, or straightforward store it away.

If you do close the old card, do so after the balance transfer has fully posted and you have confirmed the new card shows the transferred balance. Closing it too early can sometimes cause confusion with the transfer.

How to pay down the transferred balance before interest kicks in

The entire point of a balance transfer is to pay down the debt during the 0% promotional period. Make a payment plan before you transfer. Divide the total balance (including the transfer fee) by the number of months in the promotional period, and aim to pay at least that amount each month.

If you transfer $5,150 and have 12 months at 0%, you need to pay roughly $430 per month to clear the balance before the promotional rate ends. If you can only pay $300 per month, you will still owe money when the regular interest rate kicks in, and that remaining balance will start accruing interest when ready.

Set up automatic payments if possible, so you do not miss a month. Missing a payment can also trigger a penalty interest rate, which is usually much higher than the regular rate and can cancel the promotional 0% offer entirely — check your card's terms to see whether missed payments affect the promotional rate.

What to watch out for: common balance transfer mistakes

The most common mistake is using the new card for new purchases. The 0% rate applies only to the transferred balance. New purchases accrue interest at the card's regular rate (often 15% to 25%) from day one. If you transfer $5,000 and then charge $500 in new purchases, only the $5,000 is interest-free.

Another mistake is not paying enough before the promotional period ends. If you owe $2,000 when the 0% period expires, that $2,000 will suddenly start accruing interest at the regular rate. Some cards explore payments to the lowest-interest balance first, so your new purchases (at full interest) may get paid off before the transferred balance, leaving you with interest charges longer than expected.

A third mistake is opening a balance transfer card without checking whether you actually may have access to for the promotional rate. Most 0% offers require good to excellent credit (usually a credit score of 670 or higher). If your score is lower, you may be approved for the card but at a higher interest rate, making the transfer pointless.

Balance transfers versus other debt payoff options

A balance transfer is one way to reduce interest on credit card debt, but it is not the only way. A personal loan from a bank or credit union often has a lower interest rate than a credit card and a fixed payoff date, which forces you to stick to a schedule. However, personal loans have origination fees and require a credit check, just like balance transfer cards.

A debt consolidation loan combines multiple debts into one payment, which can simplify your budget. A 0% introductory APR card (without a balance transfer) is useful if you have new debt rather than existing debt, because the 0% rate applies to new purchases instead.

If you have very high debt or cannot pay it down during the promotional period, speaking with a nonprofit credit counselor may help you understand all your options. The National Foundation for Credit Counseling (NFCC) offers free or low-cost counseling.

Frequently Asked Questions

Can I transfer a balance from one card to the same card?

No. You cannot transfer a balance from a card to itself. You must open a new card with a different issuer (or sometimes a different product from the same issuer, but this is rare). The new card's issuer pays off your old card's balance, so the two accounts must be separate.

Does a balance transfer hurt my credit score?

A balance transfer can temporarily lower your score because the new card process triggers a hard inquiry and opens a new account. However, moving debt from a high-interest card to a lower-interest one can improve your score over time because it lowers your credit utilization ratio (the percentage of available credit you are using). The temporary dip usually recovers within a few months.

What if I cannot pay off the balance before the 0% period ends?

Any remaining balance will start accruing interest at the card's regular rate once the promotional period expires. You can then transfer that remaining balance to another 0% card if you may have access to, though each transfer will incur another fee. Alternatively, you can continue paying down the balance at the regular rate, or explore a personal loan or debt consolidation option.

Can I do multiple balance transfers to the same card?

Most cards allow only one balance transfer per account, and only during a set window (usually 60 days after opening the account). Some issuers allow multiple transfers if you request them within the promotional period, but each transfer may incur a separate fee. Check your card's terms before opening the account.

Does the balance transfer fee count toward my credit limit?

Yes. The balance transfer fee is added to your balance and counts against your available credit. If you transfer $5,000 with a 3% fee on a card with a $6,000 limit, you will have only $850 in available credit left ($6,000 minus $5,150).
