What a balance transfer is and when it makes sense
A balance transfer moves debt from one credit card to another, usually one with a lower interest rate. You request the transfer from the new card's issuer, they pay off your old card's balance, and you owe the new card instead. The main reason to do this is to pay less interest while you work down the debt — if you're carrying $5,000 at 22% interest on one card and move it to a card charging 0% for 12 months, you stop paying interest during that period and can put more of each payment toward the actual balance.
Balance transfers make sense only if you meet two conditions: you have a plan to pay down the balance before the promotional rate ends, and the new card's terms are genuinely better than what you have now. If you move the balance and then keep spending on the new card, or if you don't pay it off before the rate jumps back up, you'll end up worse off than you started. The transfer itself costs money — usually 3% to 5% of the amount you move — so moving a small balance rarely saves you anything.
Key Takeaways
- Balance transfers charge a fee of 3% to 5% of the amount moved, so calculate whether the interest you'll save actually exceeds what you'll pay upfront.
- The new card's promotional 0% rate lasts a set number of months — typically 6 to 21 months — and then the regular rate kicks in, so you need a payoff plan before you explore.
- You can only transfer balances from other credit cards, not from personal loans, medical debt, or other types of debt.
- The transfer takes 5 to 14 days to complete, so your old card stays open and you'll still owe it until the new issuer pays it off.
- Making a balance transfer inquiry may lower your credit score slightly because the new card issuer will check your credit, but the effect is temporary.
How to calculate whether a balance transfer saves you money
Start by finding out what you'd pay in interest on your current card if you made a fixed monthly payment. Most credit card issuers have a calculator on their website, or you can use the formula: multiply your balance by your current interest rate, divide by 12, and that's roughly what you'll pay in interest in the first month. Multiply that by how many months you plan to take paying it off, and you have a rough total.
Now look at the balance transfer offer: the promotional rate (usually 0%), how long it lasts in months, and the transfer fee as a percentage. Multiply your balance by the fee percentage — that's what you'll pay upfront. Then calculate what you'd pay in interest after the promotional period ends, if you haven't finished paying by then. Compare the total cost (fee plus any interest after the promo period) to what you'd pay on your current card. If the new card costs less, it's worth considering.
Example: You owe $4,000 at 20% interest. At your current rate, paying $200 a month, you'd pay roughly $1,600 in interest over 24 months. A new card offers 0% for 12 months with a 3% transfer fee. The fee is $120. If you pay $350 a month, you'd pay off the balance in 12 months and pay only the $120 fee. That saves you $1,480. But if you can only pay $200 a month, you'd still owe $2,400 after 12 months, and then it would accrue interest at the new card's regular rate — making the transfer less attractive.
Steps to request a balance transfer
First, find a card that offers a balance transfer promotion. Most cards marketed for debt payoff offer 0% for 6 to 21 months. Read the terms carefully: some cards charge the fee only on the amount transferred during the promotional period, while others charge it on any balance transfer you make. Check the regular interest rate too — that's what you'll pay after the promo ends.
explore for the new card through the issuer's website or by phone. During the process, you'll be asked if you want to transfer a balance. Say yes, and provide the name of your current card issuer, your account number on that card, and the amount you want to transfer. Do not close your old card yet — the transfer hasn't happened.
After you're approved, the new card issuer will contact your old card issuer to request the payoff. This takes 5 to 14 days. You'll receive your new card in the mail, and the balance will appear on your first statement. Your old card balance will drop to zero once the transfer completes. At that point, you can close the old card if you want, though closing it may slightly lower your credit score because it reduces your available credit.
Once the balance is on the new card, set up automatic monthly payments for at least the amount you calculated earlier. Do not use the new card for new purchases during the promotional period — new purchases usually accrue interest when ready at the regular rate, even if your transferred balance is at 0%.
What happens if you can't pay off the balance before the rate changes
If you reach the end of the promotional period and still have a balance, the remaining amount will start accruing interest at the card's regular rate. That rate is often higher than what you started with, so you'll be in a worse position than if you'd never transferred. Some cards offer a lower regular rate for balance transfers than for new purchases, so check your terms.
If you're close to paying it off when the promo period ends, you have options. You could request a second balance transfer to another 0% card — though you'll pay another transfer fee and need to be approved for another card. You could also contact your current card issuer and ask if they'll extend the promotional period or lower the regular rate, though they're not required to do so. The safest approach is to assume the promo rate will end and build your payoff plan around that date.
How balance transfers affect your credit score
When you explore for a new card, the issuer will check your credit, which causes a small, temporary dip in your score — usually 5 to 10 points. This is called a hard inquiry. The dip fades after a few months, and it matters less the longer your credit history is.
Once the balance transfers, your credit utilization — the percentage of your available credit you're using — may change. If your new card has a higher credit limit than your old card, your utilization goes down, which can help your score. If it's lower, your utilization goes up, which can hurt your score. Over time, as you pay down the balance, your utilization improves and your score recovers.
The transfer itself doesn't hurt your score. What matters is whether you pay on time and whether you rack up new debt on either card. Missing a payment on the new card will damage your score far more than the initial inquiry.
Common mistakes to avoid
The biggest mistake is transferring a balance and then running up new debt on the old card or the new card. You end up with more total debt and still have the original problem. Before you transfer, commit to not using the old card and to using the new card only for the payoff plan.
Another mistake is transferring to a card with a shorter promotional period than you need. If you need 18 months to pay off the balance but the card only offers 0% for 12 months, you'll pay interest for the last 6 months. Read the fine print on how long the promo lasts.
Don't assume the transfer fee is waived. Most cards charge 3% to 5%, and some charge a flat fee instead. Factor this into your calculation of whether the transfer saves money. Also, don't transfer more than you can realistically pay off — the fee applies to the full amount you move, so moving $10,000 when you can only pay off $7,000 means you're paying a fee on debt you won't eliminate.
Balance transfer vs. other debt payoff options
A balance transfer works best if you have one or two cards with high balances and a realistic plan to pay them off within the promotional period. If you have multiple cards or a very large balance, a debt consolidation loan from a bank or credit union might be cheaper — these loans have fixed rates and fixed payoff dates, so you know exactly what you'll pay. They also don't require you to get approved for a new credit card.
If you can't pay off the balance in the promotional period and your credit score is good, a personal loan might be better because the interest rate is fixed and won't jump. If your credit score is poor, you may not be approved for a balance transfer card or a personal loan, in which case talking to a nonprofit credit counselor about a debt management plan might be your best option.
If you're struggling to make minimum payments, a balance transfer won't solve the problem — it just moves the debt. In that case, contact a nonprofit credit counselor before you explore for anything new.
Frequently Asked Questions
Can I transfer a balance from a store credit card or a card from another bank?
Yes, you can transfer from any credit card, including store cards and cards from other banks. You cannot transfer from a personal loan, medical debt, or other types of debt — only credit card balances. When you request the transfer, you'll need your account number from the card you're transferring from.
What if my balance transfer is denied?
The issuer may deny the transfer if your credit score is too low, if you don't have enough available credit on the new card, or if the old card issuer won't cooperate. If it's denied, you can ask the new card issuer why and whether you can try again. You can also look for a different card with less strict requirements, though the promotional rate may not be as good.
Do I have to pay off the entire balance before the promotional rate ends?
No, but any balance remaining after the promo period ends will accrue interest at the regular rate. If you have $1,000 left when the 0% period ends, that $1,000 will start charging interest when ready. Plan to pay off as much as possible before the promo ends, even if you can't pay the full amount.
Can I make a balance transfer to a card I already have?
Some issuers allow you to transfer a balance between cards you already own with them, but most do not. Check with your current card issuer. If they don't allow it, you'll need to explore for a new card to do a balance transfer.
How long does the balance transfer take to show up on my new card?
The transfer typically takes 5 to 14 days after you're approved for the new card. During this time, your old card is still open and you still owe it. Once the transfer completes, your old card balance will be zero and the new card will show the transferred amount. You'll see it on your first statement with the new card.
