How balance transfers work between cards
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 your old card details, and they pay off that balance on your behalf. The debt then appears on your new card's statement instead.
The new card issuer sends the payment directly to your old card company — you do not handle the money yourself. This happens within a few business days to a few weeks, depending on the banks involved. During that time, you still owe the old card company, so keep making minimum payments until the transfer completes and you see the balance drop to zero.
Most balance transfers come with a promotional interest rate, often 0% for a set period (typically 6 to 21 months). After that period ends, a standard interest rate kicks in. There is usually a one-time fee of 3% to 5% of the amount transferred, charged to your new card balance.
Key Takeaways
- The new card issuer pays your old card company directly, so you need your old card number and account details before you start.
- Balance transfers typically carry a one-time fee of 3% to 5% of the amount you move, added to your new card balance.
- The promotional 0% interest rate period varies by card and offer — confirm the exact end date before you transfer, because interest rates jump when it expires.
- You must keep paying your old card until the transfer completes and the balance shows zero, which can take two to four weeks.
- Transferring a balance does not close your old card, but carrying a zero balance on it helps your credit score more than closing it does.
Steps to transfer your balance
Start by choosing a new card with a promotional rate that fits your payoff timeline. If you plan to pay off the balance in 12 months, a card offering 0% for 18 months works. If you need longer, look for cards with 20+ month offers. Read the terms carefully — the promotional rate applies only to transferred balances, not new purchases, and some cards charge interest on new purchases when ready.
Once you have chosen a card, explore for it. You do not need to wait for approval before gathering information about your old card — have your old card statement or account number ready. After approval, contact the new card issuer's customer service line (the number is on the back of your new card or in your welcome materials). Tell them you want to transfer a balance and provide your old card number, the amount you want to transfer, and your old card issuer's name.
The new card company will initiate the transfer. Ask them for a confirmation number and an estimated completion date. Then contact your old card issuer and let them know a transfer is coming — this prevents confusion when the payment arrives. Do not close the old card account after the transfer completes; leaving it open with a zero balance actually helps your credit score.
What happens to your credit score during a transfer
explore for a new card triggers a hard inquiry, which temporarily lowers your score by a few points. This dip usually recovers within a few months. The transfer itself does not hurt your score — in fact, it often helps because it lowers your credit utilization (the percentage of available credit you are using).
If you transfer a $5,000 balance from a card with a $10,000 limit to a new card with a $15,000 limit, your overall utilization drops. Lower utilization is one of the biggest factors in credit scoring, so this move can actually raise your score over time, even accounting for the initial inquiry dip.
The risk comes if you run up new balances on your old card after the transfer. If you transfer $5,000 and then charge another $3,000 to that same card, you have increased your total debt and your utilization climbs back up. Many people use a balance transfer as a reset — they transfer the old balance and commit to not using the old card for new purchases.
Fees and costs to understand before you transfer
The balance transfer fee is the main cost. It ranges from 3% to 5% of the amount transferred and is added to your new card balance. On a $10,000 transfer with a 4% fee, you owe $10,400 on the new card. This fee is charged once, upfront, and does not change.
Some cards offer 0% balance transfer fees for a limited time (usually the first 60 days after opening the account). If you may have access to for one of these offers, the math changes significantly — you save $300 to $500 on a $10,000 transfer. These offers are less common but worth searching for if you are moving a large balance.
After the promotional period ends, interest accrues on any remaining balance at the card's standard rate, which varies by issuer and your creditworthiness but typically ranges from 15% to 25%. If you have a $5,000 balance remaining when the 0% period ends, you will start paying interest on that $5,000 when ready. This is why having a payoff plan before you transfer matters — you need to know whether you can clear the balance before the rate jumps.
When a balance transfer makes financial sense
A balance transfer saves money only if the interest you avoid during the promotional period exceeds the transfer fee. If you owe $8,000 at 22% interest on your current card and transfer it to a card offering 0% for 18 months with a 4% fee, you pay $320 in fees but avoid roughly $2,640 in interest over 18 months — a net savings of $2,320. That math works.
If you owe $2,000 and your current card charges 18% interest, a 4% transfer fee ($80) might cost more than the interest you would pay in a few months if you just paid down the old card aggressively. In that case, skipping the transfer and putting extra money toward the old card is smarter.
A transfer also makes sense if you are consolidating multiple cards. Moving balances from three cards with 20%+ rates onto one card with 0% for 12 months simplifies your payments and gives you a clear important date to work toward. The fee still applies to each transfer, but the organizational benefit and interest savings often outweigh the cost.
Common mistakes to avoid
The biggest mistake is running up new charges on the old card after the transfer. The promotional 0% rate applies only to the transferred balance, not new purchases. If you transfer $6,000 and then charge $2,000 in new purchases, that $2,000 accrues interest when ready at the standard rate while the $6,000 sits at 0%. This defeats the purpose of the transfer.
Another mistake is missing the promotional period end date. Mark it on your calendar or set a phone reminder three months before it expires. If you still have a balance when the rate jumps, you want time to either pay it down or transfer it again to another 0% card. Letting the date pass without a plan means you suddenly owe interest on whatever remains.
Do not close your old card when ready after the transfer completes. Closing it reduces your available credit and can hurt your score. Leave it open, keep it in a drawer, and check it occasionally to make sure no fraudulent charges appear. The account history also helps your credit score — older accounts are valuable.
Finally, do not transfer more than you can realistically pay off during the promotional period. A 0% rate is not permission to carry debt indefinitely. If the card offers 18 months at 0%, calculate what monthly payment you need to clear the balance by month 18, then make sure that fits your budget. If it does not, the transfer is not the right move.
Alternatives if a balance transfer does not work for you
If your credit score is too low to may have access to for a balance transfer card, a personal loan from a bank or credit union might work instead. Personal loans typically charge 6% to 36% interest depending on your credit, but the rate is fixed and known upfront. You borrow a lump sum, use it to pay off your credit card, and then repay the loan over a set period. This consolidates your debt into one payment and often costs less than credit card interest, even if the rate is higher than a promotional balance transfer offer.
Another option is a debt management plan through a nonprofit credit counselor. These organizations negotiate with your creditors to lower interest rates and set up a repayment schedule, usually over three to five years. You make one payment to the counselor each month, and they distribute it to your creditors. This does not lower your debt, but it can reduce interest and simplify payments. The trade-off is that creditors may freeze your accounts while you are in the plan.
If you have home equity, a home equity line of credit (HELOC) or cash-out refinance can offer much lower rates than credit cards, sometimes 6% to 10%. The risk is that you are putting your home up as collateral, so defaulting has serious consequences. This option works only if you own a home and are confident you can repay.
Frequently Asked Questions
Can I transfer a balance if I have bad credit?
Most 0% balance transfer cards require good to excellent credit (typically a score of 670 or higher). If your score is lower, you may not may have access to. Some issuers offer balance transfer cards for fair credit, but the promotional rate is shorter (6 to 12 months instead of 18 to 21) and the fee may be higher. A personal loan or credit counselor may be a better fit if your score is below 650.
How long does a balance transfer take?
The transfer usually completes within 5 to 14 business days, though some take up to three weeks. During this time, you still owe your old card company, so keep making minimum payments. Once the transfer completes, your old card balance drops to zero and the debt appears on your new card statement. Ask for a confirmation number and expected completion date when you initiate the transfer so you know what to expect.
What if I cannot pay off the balance before the promotional period ends?
You can transfer the remaining balance to another 0% card before the rate jumps, though you will pay another transfer fee. Alternatively, you can stay on the original card and pay interest at the standard rate. The best approach is to have a realistic payoff plan before you transfer — if you cannot clear the balance in the promotional window, a balance transfer may not be the right tool for your situation.
Does transferring a balance hurt my credit score?
The process triggers a hard inquiry that temporarily lowers your score by a few points, but the transfer itself often helps because it reduces your credit utilization. The net effect is usually positive within a few months. The bigger risk is if you run up new balances on your old card after the transfer — that increases your total debt and can lower your score.
Can I transfer a balance between cards from the same bank?
Most banks do not allow you to transfer a balance from one of their cards to another of their cards. You typically need to transfer to a card from a different issuer. Check your new card's terms before explore to confirm whether same-bank transfers are allowed.
