The basic steps for transferring a balance

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 — instead, the new card's issuer pays your old card's balance on your behalf, and you then owe that amount to the new card instead.

The process itself is straightforward: you open an account with a new card issuer, provide them with your old card details and the balance amount you want to move, and they handle the payment to your old card. Most transfers complete within two to three weeks, though some take up to six weeks. During that time, you keep making minimum payments on your old card to avoid late fees.

The catch is that balance transfers are not free. 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. Some cards offer 0 percent balance transfer fees for a limited time, usually 60 days from account opening, so timing matters if you want to avoid that cost.

Key Takeaways

  • The new card issuer pays your old card directly, so you need your old card number and the exact balance you want to transfer.
  • Balance transfer fees range from 3 to 5 percent of the amount moved, though some cards waive the fee for transfers made within 60 days of opening the account.
  • The introductory interest rate (often 0 percent) applies only to the transferred balance, not to new purchases you make on the card.
  • You must make at least minimum payments during the transfer period to avoid late fees on your old card, and the transfer itself takes two to six weeks.
  • After the introductory period ends, any remaining balance reverts to the card's regular interest rate, which can be 15 to 25 percent or higher.

What you need before you start

Gather three pieces of information before you contact a new card issuer: your old card number, your old card's current balance, and the name and address of the old card's issuer. You will also need your Social Security number and current income, because the new issuer will run a credit check to decide whether to approve you and what credit limit to offer.

Check your credit report before applying. You can view it free once per year at annualcreditreport.com, which is the only official site authorized by the federal government. If your credit score is below 650, most balance transfer cards will deny you. If it is between 650 and 700, you may be approved but with a higher interest rate or lower credit limit. Knowing your score beforehand helps you target cards you actually have a chance of getting.

Also decide in advance how much of your balance you want to move. You do not have to transfer everything — you can move $3,000 of a $7,000 balance if you want. Moving less means paying less in transfer fees, but it also means more debt stays on your old card at the old interest rate. The math depends on your old card's rate and how quickly you can pay down the transferred balance.

Choosing a card and applying

Balance transfer cards differ mainly in three ways: the length of the introductory 0 percent period, the regular interest rate that kicks in after, and the balance transfer fee. A card with a 12-month 0 percent offer and a 3 percent fee is usually better than one with an 18-month offer and a 5 percent fee, because the fee difference ($100 on a $5,000 transfer) often outweighs the extra months of 0 percent interest.

Read the card's terms document carefully — not the marketing materials, but the actual terms and conditions. Look for the exact date the introductory period ends, whether the fee applies to all transfers or only some, and what the regular APR (annual percentage rate) will be after the intro period. Some cards also charge a fee for transferring a balance from another card issued by the same company, so if you are moving a balance between two cards from the same bank, check whether that is allowed.

Apply online or by phone. Most issuers give you a decision within minutes to a few days. If you are approved, the issuer will ask you to confirm the transfer details — your old card number, the amount, and the old card issuer's name. At that point, the transfer is in motion.

What happens after you are approved

Once approved, you will receive your new card in the mail within 7 to 10 business days. You do not need to wait for the physical card to arrive to initiate the balance transfer — you can often start it online or by phone as soon as your account is open. The issuer will send a check or electronic payment to your old card issuer on your behalf.

During the transfer period (usually 2 to 6 weeks), keep paying your old card's minimum payment. The old card is still active and still accruing interest on any balance that has not yet been paid off by the transfer. Missing a payment during this window can trigger a late fee and damage your credit score, even though you are in the process of moving the balance.

Once the transfer completes, your old card's balance will drop to zero (or to whatever amount you did not transfer). At that point, you can stop using the old card, but do not close the account immediately. Closing a credit card account can lower your credit score because it reduces your total available credit. Instead, leave it open with a zero balance and use it occasionally for a small purchase you pay off right away, just to keep the account active.

Avoiding the trap of new purchases

The 0 percent introductory rate applies only to the transferred balance, not to new purchases. If you make a $500 purchase on your new balance transfer card, that $500 is charged the regular APR (often 18 to 24 percent) immediately, even though your transferred balance sits at 0 percent. This is one of the biggest mistakes people make with balance transfer cards.

To avoid this trap, treat your new card as a transfer-only tool. Do not use it for everyday purchases. If you need a card for regular spending, use a different card — one without a balance on it, or one with a lower interest rate. Keep your new balance transfer card in a drawer and pull it out only if you need to transfer another balance later.

Also watch out for the "interest free period" ending. When the introductory rate expires, any remaining balance on the transferred amount will suddenly start accruing interest at the regular rate. If you transferred $5,000 and have paid down $3,000, the remaining $2,000 will jump from 0 percent to 18 percent or higher. This is why it is important to have a payoff plan before you transfer — you want to eliminate as much of the balance as possible before the clock runs out.

When a balance transfer makes sense

A balance transfer is worth doing if your old card's interest rate is significantly higher than the new card's introductory rate, and if you have a realistic plan to pay down the balance before the intro period ends. If you are paying 22 percent on a $4,000 balance and you can move it to 0 percent for 12 months, you save roughly $880 in interest over that year — even after paying a $160 transfer fee (4 percent), you come out $720 ahead.

A balance transfer does not make sense if you cannot pay down the balance before the introductory period ends, or if the transfer fee is so high that it wipes out the interest savings. It also does not make sense if your credit score is too low to get approved for a card with a meaningful introductory rate. In that case, you are better off focusing on paying down your current balance as aggressively as possible, even at the higher interest rate.

What to do if your transfer is denied

If you apply for a balance transfer card and are denied, the issuer will send you a letter explaining why — usually because your credit score is too low, your income is too high relative to your debt, or you have too many recent credit inquiries. Do not apply for multiple cards in quick succession trying to get approved; each application triggers a hard inquiry on your credit report, and multiple inquiries in a short time can lower your score further.

Instead, focus on paying down your current balance for three to six months before applying again. Even a small reduction in what you owe can improve your debt-to-income ratio and make you a more attractive candidate. You can also look for balance transfer cards that explicitly accept applicants with fair credit (scores between 650 and 700), though these usually have higher fees or shorter introductory periods.

Frequently Asked Questions

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

Most banks do not allow you to transfer a balance between their own cards. Check the card's terms before applying. If the same bank issued both cards, you will likely need to use a different issuer's card to move the balance.

What happens to my old card after the balance is transferred?

Your old card remains open with a zero balance. You can leave it open (which helps your credit score by keeping your available credit high) or close it later, though closing it may temporarily lower your score. Do not close it immediately after the transfer.

Do I have to transfer my entire balance, or can I move just part of it?

You can transfer any amount up to your old card's balance. Transferring less means paying less in transfer fees, but more debt stays on your old card at the old interest rate. Calculate which approach saves you more money based on how quickly you can pay down the transferred balance.

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

Any remaining balance will be charged the card's regular interest rate, which is usually 15 to 25 percent. If you know you cannot pay it off in time, a balance transfer may not be worth the transfer fee. Focus instead on paying down your current balance as much as possible before the intro period expires.

Does a balance transfer hurt my credit score?

A balance transfer temporarily lowers your score because the credit inquiry and new account opening count against you. However, your score usually recovers within a few months, especially if you make on-time payments and keep your credit utilization low on the new card.
