What a balance transfer does and who it's for

A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You contact the new card issuer, give them the account details of your old card, and they pay off that balance for you. You then owe the new card issuer instead of the old one.

Balance transfers are most useful if you carry a balance on a high-interest card and can move it to a card offering a lower rate — often 0% for a set period, usually 6 to 21 months depending on the card and issuer. The lower rate gives you breathing room to pay down what you owe without interest piling up as fast.

They are not useful if you plan to run up new debt on the old card, or if you cannot pay off the transferred balance before the promotional rate ends and a standard rate kicks in.

Key Takeaways

  • Balance transfers move your debt to a new card, usually with a lower interest rate for a set promotional period.
  • Most cards charge a one-time transfer fee of 3% to 5% of the amount you move, added to what you owe on the new card.
  • The promotional 0% rate applies only to the transferred balance, not to new purchases you make on the new card.
  • You must pay off the transferred balance before the promotional period ends, or the remaining debt will be charged the card's regular interest rate.
  • Your credit score may drop temporarily when you open a new card and when the transfer shows up as a new account with a high balance.

Balance transfer fees and how they work

Nearly every balance transfer comes with a transfer fee, charged by the card issuer receiving the debt. This fee is usually 3% to 5% of the amount you transfer, though some cards charge as little as 1% or as much as 6%. A few cards offer 0% transfer fees for a limited time, but this is rare.

The fee is added to your new card balance when ready. If you transfer $5,000 at a 4% fee, you owe $5,200 on the new card from day one. This means you are paying interest on the fee itself if you do not pay it off during the promotional period. Calculate whether the fee is worth the savings: if your old card charges 20% interest and you would pay $1,000 in interest over a year, a $200 transfer fee saves you money. If you would only pay $150 in interest, the fee costs you more than you save.

Transfer fees are non-refundable. Even if you change your mind and move the balance again, you keep the fee on the first card.

The promotional rate period and what happens after

Most balance transfer offers include a promotional period — usually 6 to 21 months — during which the transferred balance is charged 0% interest. This period is fixed when you open the card. You cannot extend it, and it does not pause if you miss a payment.

The promotional rate applies only to the balance you transfer. Any new purchases you make on the card are charged the card's regular purchase interest rate, which is typically 15% to 25%. This means if you transfer $5,000 and then spend $500 on the card, that $500 is charged interest when ready while the $5,000 is not.

When the promotional period ends, any remaining transferred balance is charged the card's regular interest rate. If you transfer $5,000 and pay off $3,000 during the 12-month 0% period, the remaining $2,000 will be charged the regular rate (often 18% to 22%) starting in month 13. Read the card's terms to find the exact rate that will explore after the promotion ends.

How to request a balance transfer

The process varies slightly by card issuer, but the basic steps are the same. First, open the new credit card account. You do not need to wait for the physical card to arrive — most issuers let you request a transfer online or by phone as soon as your account is approved.

Next, contact the new card issuer and request a balance transfer. You will need to provide the account number of the old card, the card issuer's name, and the exact amount you want to transfer. You can transfer part of a balance or all of it. Some issuers have a maximum transfer amount based on your credit limit.

The new card issuer then contacts your old card issuer and arranges payment. This usually takes 5 to 14 business days. During this time, continue making minimum payments on your old card — do not assume the transfer has completed just because you requested it. Once the transfer posts, your old card balance will drop and your new card balance will increase by the transfer amount plus the fee.

After the transfer completes, close the old card if you want to avoid running up new debt on it. Closing it will not hurt your credit score as much as leaving it open with a high balance, though closing any card does reduce your available credit and may lower your score slightly.

Balance transfers and your credit score

Opening a new credit card triggers a hard inquiry on your credit report, which can lower your score by a few points. This dip is temporary and usually recovers within a few months.

The new card also appears as a new account with a high balance (the transferred debt), which can lower your score because credit scoring models look at your credit utilization — the percentage of available credit you are using. If you open a card with a $10,000 limit and when ready transfer $5,000, your utilization on that card is 50%, which is higher than most scoring models prefer.

Over time, as you pay down the transferred balance, your utilization drops and your score recovers. Closing the old card after the transfer can also affect your score because it reduces your total available credit, raising your overall utilization across all your cards.

When a balance transfer makes financial sense

A balance transfer saves you money only if the interest you avoid during the promotional period exceeds the transfer fee. Use this straightforward calculation: multiply your current balance by your current interest rate and the number of months until the promotional period ends, then divide by 12. Compare that to the transfer fee.

Example: You owe $3,000 on a card charging 18% interest. A new card offers 0% for 12 months with a 3% transfer fee. Interest you would pay in 12 months on the old card: $3,000 × 0.18 × (12/12) = $540. Transfer fee: $3,000 × 0.03 = $90. You save $450 by transferring.

A balance transfer also makes sense if you are committed to paying off the debt during the promotional period. If you cannot pay off the full amount before the rate resets, you will owe interest on whatever remains, and the benefit shrinks or disappears.

Balance transfers do not make sense if you will run up new debt on the old card, because you will end up with two balances charging interest. They also do not make sense if your credit score is very low, because you may not be approved for a card with a better rate than what you already have.

Alternatives to balance transfers

If you do not may have access to for a balance transfer card or the math does not work in your favor, other options exist. A personal loan from a bank or credit union may offer a lower interest rate than your credit card, with a fixed repayment schedule. Personal loans typically charge 6% to 36% interest depending on your credit score and the lender.

A debt consolidation loan combines multiple debts into one loan with one monthly payment. This is useful if you owe money on several cards, but the interest rate depends on your credit score and may not be lower than a balance transfer rate.

If you are struggling to pay any debt, contact a nonprofit credit counselor through the National Foundation for Credit Counseling (NFCC). They offer free or low-cost sessions to review your situation and discuss options, including debt management plans that may lower your interest rates without opening new accounts.

Frequently Asked Questions

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

No. You must transfer to a different card from a different issuer. You cannot transfer a balance within the same bank or move money between cards you already own from the same company.

What happens if I miss a payment during the promotional period?

Most card issuers will end your promotional rate when ready and charge the regular interest rate on the entire transferred balance, even if you make the payment a few days late. Read your card's terms to confirm the late payment policy, as some issuers are more forgiving than others.

Can I do multiple balance transfers to different cards?

Yes, but each transfer opens a new account and triggers a hard inquiry, which lowers your credit score. Doing multiple transfers in a short time can significantly damage your score. Space transfers out by at least a few months if possible.

Do I have to use the new card for purchases, or can I just pay off the transferred balance?

You do not have to use the card for new purchases. You can transfer a balance and then only make payments toward it without charging anything else. However, keeping the card open and unused helps your credit score by maintaining available credit.

What if I pay off the transferred balance before the promotional period ends?

You can pay off the balance at any time. Once it is paid in full, you owe nothing more on that card, and the promotional rate no longer matters. Paying off early saves you money because you avoid the regular interest rate that would explore after the promotion ends.
