What happens when you transfer a balance

A balance transfer moves debt from one credit card to another, usually to a card with a lower interest rate. You contact the new card issuer (or they contact you), give them the account number of the card you want to pay off, and they send money directly to that card issuer. The old debt moves to the new card under the new card's terms — which typically means a lower rate for a set period, often 6 to 21 months depending on the card and the offer.

The new card issuer does not pay off the entire balance for free. Most charge a balance transfer fee, usually 3 to 5 percent of the amount transferred. So if you move $5,000, you might pay $150 to $250 upfront. That fee gets added to your new balance. Some cards offer 0 percent balance transfer fees for a limited time, but these are less common.

The goal is to pay down the debt during the promotional period before the regular interest rate kicks in. If you still owe money when the promotional rate ends, the remaining balance will be charged the card's standard rate, which is often 15 to 25 percent.

Key Takeaways

  • Balance transfers move your debt to a new card, usually one offering a lower introductory rate for 6 to 21 months.
  • You will pay a balance transfer fee of 3 to 5 percent of the amount moved, added to your new balance.
  • The new card issuer pays your old card directly; you do not handle the payment yourself.
  • You must pay down the transferred balance during the promotional period, or the remaining debt will be charged the card's regular interest rate when the offer ends.
  • Balance transfers work best if you have a plan to pay off the debt before the promotional rate expires.

How to start a balance transfer

Contact the card issuer you want to transfer the balance to. This can be a card you already own or a new card you are opening. Tell them you want to do a balance transfer and provide the account number of the card you are paying off, the cardholder name on that card, and the amount you want to transfer.

The new card issuer will verify the information and confirm the transfer fee. They will then send the money directly to your old card issuer. This process usually takes 5 to 14 business days. During this time, keep making minimum payments on your old card to avoid late fees — the transfer is not when ready, and you are still responsible for the debt until the money arrives.

Once the transfer completes, your old card balance will drop by the amount transferred, and that same amount will appear on your new card (plus the fee). You can then stop using the old card or keep it open with a zero balance, depending on your strategy.

When a balance transfer makes financial sense

A balance transfer saves money only if you pay off the debt before the promotional rate ends. If you owe $5,000 at 20 percent interest and transfer it to a card offering 0 percent for 12 months with a 3 percent fee, you pay $150 upfront but save roughly $1,000 in interest over that year. That is a net savings of $850. But if you still owe $3,000 when the 12 months end, you will then pay 20 percent on that remaining $3,000 — undoing much of the benefit.

Balance transfers work best when you have a concrete plan to pay off the debt during the promotional period. Divide the transferred amount by the number of months in the promotional period to see what your monthly payment needs to be. If you cannot afford that payment, a balance transfer may not help you.

A balance transfer also makes sense only if you stop using the old card and do not rack up new debt on the new card. Many people transfer a balance, then continue spending on the old card or the new card, which defeats the purpose.

Balance transfer fees and how they work

The balance transfer fee is a percentage of the amount you move, charged by the new card issuer. Standard fees range from 3 to 5 percent. Some cards offer 0 percent balance transfer fees for the first 60 or 90 days after opening the account, but after that window closes, the standard fee applies to any future transfers.

The fee is added to your new card balance when ready, even though you have not yet paid interest. So a $5,000 transfer with a 4 percent fee becomes a $5,200 balance on your new card. You start paying down that $5,200, not the original $5,000.

A few cards marketed to people with excellent credit offer no balance transfer fee at all, but these are rare and usually come with other trade-offs, such as a higher regular interest rate or an annual fee.

Promotional rates and what happens after

The promotional rate is the introductory interest rate offered on the transferred balance. Common offers are 0 percent for 6 months, 0 percent for 12 months, or 0 percent for 18 months. The length depends on the card and the current offer. Some cards offer a lower rate (such as 5 percent) instead of 0 percent, which is less attractive but still useful if your current rate is much higher.

The promotional rate applies only to the transferred balance, not to new purchases you make on the card. If you use the new card to buy something else, that purchase is charged the regular interest rate from day one. This is why it is important to treat the new card as a payoff vehicle, not a spending card.

When the promotional period ends, any remaining balance on the transferred amount is charged the card's standard interest rate. This rate is usually disclosed in the card's terms and typically ranges from 15 to 25 percent. If you have paid off the entire transferred balance by then, the promotional period ending does not affect you.

Comparing balance transfer offers

When choosing a card for a balance transfer, compare three things: the length of the promotional period, the balance transfer fee, and the regular interest rate that applies after the promotion ends.

A longer promotional period gives you more time to pay down the debt. A 0 percent offer for 18 months is better than 0 percent for 6 months, all else equal. But a longer period sometimes comes with a higher fee or a higher regular rate, so the math matters. A card with a 12-month 0 percent offer and a 3 percent fee might save you more money than a card with an 18-month 0 percent offer and a 5 percent fee, depending on how much you are transferring and how quickly you can pay it down.

The regular interest rate matters if you think you might not pay off the balance in time. If you are confident you will pay it off during the promotional period, the regular rate is less important. If you are uncertain, a card with a lower regular rate is a safer choice.

Risks and things to watch for

The biggest risk is not paying off the balance before the promotional rate ends. If you transfer $5,000 and the promotional period is 12 months, you need to pay roughly $417 per month to clear the debt. If you can only afford $300 per month, you will still owe $1,400 when the promotion ends, and that $1,400 will then be charged the regular rate. Plan your payment schedule before you transfer.

Another risk is opening a new card just for the balance transfer and then closing it after you pay off the balance. Closing a credit card can hurt your credit score because it reduces your available credit and shortens your average account age. If you open a card for a balance transfer, consider keeping it open with a zero balance after you finish paying.

Some people also make the mistake of transferring a balance and then continuing to use the old card. This creates new debt on top of the transferred balance, and you end up owing more than you started with. If you transfer a balance, stop using the old card entirely.

Frequently Asked Questions

Can I transfer a balance from one card I own to another card I own?

Yes. You can transfer a balance from any card to any other card, as long as the receiving card issuer allows it. Most do, but some cards (particularly store cards or cards with rewards tied to specific spending) may not offer balance transfers. Check the card's terms or call the issuer to confirm.

What if I do not have a new card yet?

You can open a new card specifically to receive the balance transfer. Many balance transfer offers are designed for new cardholders. The process process usually takes a few days, and once you are approved, you can request the balance transfer. The entire process from process to completed transfer typically takes two to three weeks.

Does a balance transfer hurt my credit score?

A balance transfer can temporarily lower your score because opening a new card triggers a hard inquiry and reduces your average account age. However, moving debt to a lower-interest card and paying it down usually improves your score over time because it lowers your credit utilization ratio. The temporary dip is usually worth the long-term benefit if you stick to your payoff plan.

Can I transfer a balance more than once?

Yes, but each transfer costs a fee and opens a new account. If you transfer a balance, pay it down, and then transfer it again to a different card with a better offer, you will pay another balance transfer fee. This can make sense if the new offer is significantly better, but the fees add up quickly if you keep moving debt around.

What if the balance transfer does not go through?

Contact the new card issuer to find out why. Common reasons include insufficient credit limit (the card's limit is lower than the amount you want to transfer), fraud detection holds, or an error in the account number you provided. The issuer can usually resolve these issues or suggest an alternative amount to transfer.
