The basic steps to move a balance from one card to another

A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You do not pay off the old card first — the new card's issuer pays the old card directly, and you then owe the new card instead.

The process takes about five to seven business days from the moment you request it. You initiate the transfer through the new card's website or by calling the issuer, provide the old card's account number and the amount you want to move, and the new issuer handles the rest. The old card account stays open unless you close it yourself, though the balance will drop to zero once the transfer posts.

Most cards charge a balance transfer fee — typically 3 to 5 percent of the amount you move. A $5,000 transfer at 4 percent costs $200 upfront. This fee is usually added to your new balance, so you owe it along with the transferred amount. Some cards offer 0 percent fee transfers for a limited time, though these are rare and usually only for new cardholders with strong credit.

Key Takeaways

  • The new card's issuer pays your old card directly, so you do not need to make a payment yourself to complete the transfer.
  • Balance transfer fees range from 3 to 5 percent of the amount moved and are added to your new balance, not charged separately.
  • The introductory interest rate period on the new card typically lasts 6 to 21 months, depending on the card and issuer.
  • You must request the transfer through the new card's issuer, not through your old card, and the process takes five to seven business days to complete.
  • If you do not pay off the transferred balance before the introductory period ends, the regular interest rate kicks in and can be higher than your old card's rate.

Choosing a card with a low or zero introductory rate

The whole point of a balance transfer is to buy time at a lower rate. Look for cards advertising a 0 percent introductory period on balance transfers — this is the rate you will pay during the promotional window, which typically lasts 6 to 21 months depending on the card.

Read the fine print carefully. The introductory rate applies only to transferred balances, not to new purchases you make on the card. Some cards offer 0 percent on both; most do not. Also check what the regular rate will be after the intro period ends — it can range from 15 to 25 percent, and knowing this matters if you cannot pay off the balance in time.

Cards with longer introductory periods (18 months or more) usually require good to excellent credit — typically a credit score of 670 or higher. If your score is lower, you may still find cards with shorter intro periods (6 to 12 months) that will take you. Use a card comparison site or your bank's website to see what you might may have access to for before you formally request anything.

Calculating whether the transfer actually saves you money

A balance transfer only saves money if you pay off the debt before the introductory period ends. The math is straightforward: take the balance transfer fee, add the interest you will pay during the intro period (usually zero), and compare that total to what you would pay in interest on your old card over the same timeframe.

Example: You have a $5,000 balance on a card charging 22 percent interest. A new card offers 0 percent for 12 months with a 4 percent transfer fee. The fee is $200. On your old card, you would pay roughly $1,100 in interest over 12 months if you made minimum payments. By transferring, you pay $200 in fees and zero in interest — a savings of $900, assuming you pay the full $5,200 (balance plus fee) within 12 months.

If you cannot pay it off in time, the math flips. Once the intro period ends and the regular rate kicks in, you are now paying interest on a higher balance (because the fee was added). If the new card's regular rate is higher than your old card's rate, you have made your situation worse. Use an online balance transfer calculator to run your specific numbers before you commit.

What information you need to request the transfer

Have these details ready before you contact the new card issuer:

  • Your old card number (the one you are transferring from)
  • The exact amount you want to transfer
  • Your old card issuer's name (Visa, Mastercard, American Express, Discover, or the bank that issued it)
  • Your current mailing address

You do not need to contact your old card issuer or make any payment to them. The new issuer handles all communication with the old card company. You also do not need to close the old card account — in fact, closing it can hurt your credit score by reducing your available credit. Leave it open with a zero balance.

Some issuers let you request a transfer online through your account dashboard; others require a phone call. Check the new card's website for the transfer option, or call the number on the back of your new card if you have already received it. If you have not received the card yet, you may need to wait until it arrives before you can initiate the transfer.

How long the transfer takes and when interest starts

The transfer typically posts within five to seven business days. During this time, you still owe your old card issuer — do not stop making payments to the old card until you see the balance drop to zero. If you miss a payment during the transfer window, it can damage your credit score and may disqualify you from the introductory rate on the new card.

Interest on the transferred balance does not start until the introductory period ends. If your intro period is 12 months, you have 12 months from the date the transfer posts to pay down the balance without accruing interest. Mark the end date on your calendar — issuers do not always send a reminder, and missing it means the regular rate applies immediately.

New purchases you make on the new card may start accruing interest right away, even during the intro period, unless the card specifically offers 0 percent on purchases too. To avoid confusion, do not use the new card for purchases while you are paying off the transferred balance. Keep it for the transfer only.

What happens if you cannot pay off the balance in time

If the balance is not paid in full by the time the introductory period ends, the regular interest rate applies to whatever remains. This can be a higher rate than you had on your original card, which means you have actually worsened your situation by transferring.

Some issuers offer a grace period of a few days after the intro period ends, but do not count on it. The safest approach is to set a payoff deadline one month before the intro period actually ends, giving yourself a buffer. If you realize you cannot pay it off in time, look for another card with a new introductory period and transfer again — though each transfer adds another fee, so this only makes sense if the new card's intro period is long enough to offset the cost.

If you are struggling to pay down the balance, contact your card issuer before the intro period ends. Some will negotiate a lower regular rate or extend the promotional period if you have been making on-time payments. It never hurts to ask, and the worst they can say is no.

Balance transfer versus other debt-reduction options

A balance transfer is one tool among several. If you have multiple cards with high balances, a personal loan might be simpler — you get one fixed payment and one interest rate, and you pay off all the cards at once. Personal loans typically charge 6 to 36 percent interest depending on your credit score, so compare that to what you would pay with a balance transfer plus the fee.

If you own a home, a home equity line of credit (HELOC) or cash-out refinance can offer lower rates than either option, though they put your house at risk if you cannot pay. If you are trying to pay down debt while keeping your credit score intact, a balance transfer is usually better than a debt consolidation loan because it does not require a hard credit inquiry (though the new card will do one).

If your credit score is very low (below 600), you may not may have access to for a balance transfer card at all. In that case, focus on paying down your current cards aggressively, or look into a credit counseling service through the National Foundation for Credit Counseling, which offers free or low-cost debt management plans.

Frequently Asked Questions

Can I transfer a balance from one card to the same bank's other card?

Most banks do not allow you to transfer a balance between their own cards. You typically need to transfer to a card from a different issuer. Check your bank's policy before you apply for a new card, or call and ask directly — the rules vary by institution.

Does a balance transfer hurt my credit score?

Yes, temporarily. The new card issuer does a hard credit inquiry, which lowers your score by a few points. Opening a new account also lowers your average account age. However, the transfer itself reduces your overall credit utilization (the amount of available credit you are using), which helps your score. Most people see their score recover within a few months if they make on-time payments.

What if my balance transfer is denied?

The issuer may deny the transfer if the amount exceeds your credit limit on the new card, or if the old card account is closed or in default. If denied, contact the issuer to ask why. You may be able to request a smaller transfer amount, or you may need to wait and reapply once your credit situation improves.

Can I transfer a balance to a card I just applied for but have not received yet?

Most issuers require you to receive and activate the card before you can initiate a transfer. Some allow you to request a transfer online before the card arrives, but you will need to activate it first. Call the issuer's customer service number to ask about their specific policy.

Should I close my old card after the balance is transferred?

No. Closing the account reduces your available credit and can hurt your credit score. Leave the old card open with a zero balance. You can stop using it, but keeping the account active is better for your credit profile.
