What happens when you transfer a balance
A balance transfer moves debt from one credit card to another, usually to a card offering a lower interest rate for a set period. You contact the new card issuer (or they contact you), provide the account number of the card you want to pay off, and they send the money directly to that card's bank. The old card balance drops to zero, and the new card's balance increases by that amount plus a one-time transfer fee.
The goal is to pay down the debt faster because you're not paying interest, or paying much less of it, during the promotional period. That period typically lasts 6 to 21 months depending on the card and the offer. After it ends, any remaining balance reverts to the card's regular interest rate, which is usually high.
Key Takeaways
- Balance transfers charge a fee upfront — usually 3 to 5 percent of the amount you move — so the math only works if the interest you save exceeds that cost.
- You must have a credit card already open with a promotional balance transfer offer, or you need to open one before you can initiate the transfer.
- The card issuer pays your old card directly, so you don't handle the money yourself; the transfer typically completes in 7 to 14 days.
- Any new purchases on the balance transfer card usually accrue interest when ready at the regular rate, so avoid using it for new spending during the promotional period.
- You must pay down the transferred balance before the promotional rate ends, or the remaining amount will be charged the card's standard interest rate.
Decide whether a balance transfer makes financial sense
Before you start, calculate whether you'll actually save money. The transfer fee is typically 3 to 5 percent of the amount you move. If you're transferring $5,000 at 4 percent, that's a $200 fee added to your new card balance when ready.
Next, compare what you're paying now to what you'll pay after the transfer. If your current card charges 22 percent interest and the new card offers 0 percent for 12 months, figure out how much interest you'd pay in that year on your current card, then subtract the transfer fee. If the savings exceed the fee, the transfer is worth doing. If they're close or the fee is larger, skip it.
Also check the regular interest rate on the new card — the one that kicks in after the promotional period ends. If it's similar to your current card's rate, you haven't solved your problem, only delayed it.
Open a balance transfer card if you don't have one
You need a credit card with a balance transfer offer already in place. If you don't have one, you'll need to open a new card first. Search for cards advertising 0 percent introductory rates on balance transfers. Most major card issuers — Chase, Capital One, American Express, Citi, Bank of America — offer these periodically.
When you open the card, the issuer will perform a hard credit inquiry and report the new account to the credit bureaus. This can temporarily lower your credit score by a few points. You'll receive the card in the mail within 7 to 10 business days, and you can usually initiate a balance transfer before the card arrives by using the temporary card number provided online.
Read the offer terms carefully. The promotional rate applies only to balances transferred within a specific window — often 60 days from account opening. If you miss that window, the transfer will be charged at the regular rate.
Gather the information you need to initiate the transfer
Have these details ready before you contact the new card issuer:
- The account number of the credit card you want to pay off
- The name of the bank or card issuer that holds that account
- The current balance you want to transfer (you can transfer less than the full balance if you choose)
- Your new card number (or the temporary number if the physical card hasn't arrived)
You'll also need to confirm your address and possibly answer security questions to verify your identity. The new card issuer will contact the old card's bank to confirm the account exists and the balance amount.
Request the balance transfer from your new card issuer
Contact the new card company by phone, online portal, or mobile app. Most issuers have a dedicated balance transfer section in their online account or app where you can enter the old card details and the amount you want to move.
If you call, a representative will walk you through the process and confirm the details. They'll tell you the transfer fee (calculated as a percentage of the amount), the promotional interest rate, and the length of the promotional period. They'll also confirm when the transfer should complete — typically 7 to 14 business days, though some take up to 21 days.
Ask the representative to note in your account that you've initiated a transfer. This is useful if you need to contact your old card issuer to explain why a large payment is coming in.
Monitor the transfer and avoid new charges
Check your new card's online account or app a few days after initiating the transfer. You should see the transferred balance appear within the timeframe the issuer quoted. The transfer fee will be added to your balance when ready.
Do not use the new card for new purchases during the promotional period. Any new charges will accrue interest at the regular rate right away, not the promotional rate. If you need to use a credit card for new spending, use a different card.
Keep your old card open even after the balance is paid off. Closing it can hurt your credit score by reducing your available credit and shortening your credit history. straightforward stop using it.
Create a payoff plan before the promotional rate ends
The promotional period is your window to pay down the debt without interest working against you. Calculate how much you need to pay each month to eliminate the balance before the rate expires. If you're transferring $5,000 with a 12-month promotional period, you'd need to pay roughly $417 per month to clear it (plus the transfer fee).
Set up automatic payments from your bank account to the new card if possible. This removes the risk of missing a payment, which would trigger a penalty rate and end the promotional offer early on some cards. Even one missed payment can disqualify you from the 0 percent rate.
If you can't pay off the full balance before the promotional period ends, pay as much as you can. Any remaining balance will be charged the regular interest rate, but at least you've reduced what that rate applies to.
Frequently Asked Questions
Can I transfer a balance from one card to the same issuer's other card?
Most issuers don't allow you to transfer a balance between their own cards. You typically must transfer to a card from a different bank. Check the terms of the promotional offer to confirm.
What happens if I miss a payment during the promotional period?
A missed payment usually triggers a penalty interest rate when ready, ending your 0 percent promotional rate. The remaining balance will then accrue interest at the penalty rate, which is typically higher than the regular rate. Make payments on time to protect the offer.
Can I transfer a balance from a store credit card?
Yes, you can transfer balances from store cards, gas cards, or any credit card. The process is the same — you provide the account number and the issuer handles the rest. The transfer fee still applies.
What if the transfer doesn't go through?
Contact the new card issuer to ask why. Common reasons include the old card account being closed, fraud flags, or incorrect account information. The issuer can tell you what went wrong and whether you can resubmit the request.
Do I need to pay the transfer fee upfront?
No. The fee is added to your new card balance, so you pay it off as part of the transferred debt. If you pay off the balance before the promotional period ends, you'll have paid the fee as part of that payoff.
