What happens when you move debt from one card to another
A balance transfer moves an existing debt from one credit card to a different card, usually one with a lower interest rate. You contact the new card issuer, give them the account number of your old card, and they pay off that balance on your behalf. You then owe the new card issuer instead of the old one. The point is to reduce the interest you pay while you work down the debt.
The new card typically offers a promotional period — often 6 to 21 months depending on the card — during which the interest rate is 0% or very low. After that period ends, the remaining balance reverts to the card's standard interest rate. The catch is that most cards charge an upfront fee, usually 3% to 5% of the amount transferred, added to your new balance when ready.
Key Takeaways
- The new card issuer pays off your old card directly, and you owe the new issuer the same amount plus a transfer fee of 3% to 5%.
- You have a promotional period of 6 to 21 months at a reduced or 0% interest rate, after which the standard rate applies to any remaining balance.
- The transfer fee is charged upfront and added to your balance, so a $5,000 transfer with a 4% fee means you owe $5,200 when ready.
- If you do not pay off the balance before the promotional period ends, interest accrues on the remaining amount at the card's regular rate.
- You must make at least the minimum payment each month, or you risk losing the promotional rate and facing late fees.
How the transfer fee works and what it costs you
The transfer fee is not optional — it is built into the offer. When you transfer $5,000 at a 4% fee, the card issuer adds $200 to your balance, so you now owe $5,200. This fee is charged when ready, not spread over time. Some cards advertise "0% for 18 months" but do not mention the fee prominently; read the terms carefully to see the exact percentage.
The fee makes sense only if the interest you save during the promotional period exceeds what you pay upfront. If you transfer $5,000 at 4% fee ($200) to a 0% card for 12 months, and your old card charged 20% interest, you would have paid $1,000 in interest over that year. The $200 fee is worth it. But if you transfer the same amount to a 0% card for only 6 months, you save only $500 in interest, making the fee less attractive.
The promotional period and what happens after
The promotional period is the window during which you pay reduced or no interest on the transferred balance. This period varies by card and by offer — some are as short as 6 months, others extend to 21 months. During this time, any payment you make goes toward reducing the principal, not toward interest.
Once the promotional period ends, the interest rate jumps to the card's standard rate, which is typically 15% to 25% depending on your credit score and the card's terms. If you still owe $2,000 when the promotion ends, you start paying interest on that $2,000 at the full rate. This is why the goal is to pay off as much as possible before the promotion expires. Even paying an extra $100 or $200 per month during the promotional period can significantly reduce what you owe when the rate increases.
How to calculate whether a balance transfer saves you money
Start with three numbers: the amount you are transferring, the fee percentage, and the promotional interest rate and length. Then compare that to what you would pay if you kept the debt on your current card.
Example: You have $6,000 on a card charging 22% interest. A new card offers 0% for 12 months with a 3% transfer fee. The fee is $180, so you owe $6,180 on the new card. On your old card, you would pay roughly $1,320 in interest over 12 months (this varies based on how much you pay down each month). By transferring, you save about $1,140 even after paying the fee. But this only works if you do not add new charges to either card and you make regular payments.
If you transfer to a card with a 0% period of only 6 months, the math changes. You would save roughly $660 in interest over 6 months, but still pay the $180 fee, netting only $480 in savings. The longer the promotional period, the more you save.
What you need to do before and during the transfer
Before you explore, check your credit score. Balance transfer cards typically require a credit score of 670 or higher, though some accept scores as low as 600. The better your score, the longer the promotional period and the lower the fee you may receive.
Once you are approved for the new card, contact the issuer and request the balance transfer. You will need the account number of the card you want to pay off, the amount to transfer, and the name and address of the old card issuer. The new issuer will then contact the old one and arrange payment. This process usually takes 5 to 14 business days. During this time, keep making minimum payments on your old card to avoid late fees.
After the transfer posts, do not close the old card. Closing it can hurt your credit score by reducing your available credit and shortening your credit history. Instead, leave it open with a zero balance and do not use it.
What happens if you miss a payment or add new charges
Missing a payment on the new card can trigger two consequences. First, you may lose the promotional rate when ready and revert to the standard interest rate on the transferred balance. Second, you will owe a late fee, typically $25 to $40. Even one missed payment can erase the savings from the transfer.
New charges you make on the new card are not covered by the promotional rate. They accrue interest at the standard rate from day one. Many people transfer a balance and then use the card for new purchases, which defeats the purpose. Treat the new card as a payoff vehicle, not a spending card, during the promotional period.
Alternatives if a balance transfer does not fit your situation
A balance transfer works best if you have a credit score above 670, can pay down the debt within the promotional period, and will not add new charges to the card. If none of these explore, other options exist.
A personal loan from a bank or credit union often has a fixed interest rate and a set repayment term, making it easier to budget. The interest rate is usually lower than a credit card's standard rate but higher than a balance transfer promotion. A debt consolidation loan combines multiple debts into one payment, which simplifies your monthly obligations. A debt management plan through a nonprofit credit counselor negotiates with your creditors to lower interest rates and set a repayment schedule, though it requires closing the accounts involved.
Frequently Asked Questions
Can I transfer a balance from one card to the same card?
No. You cannot transfer a balance to the card you already owe on. You must open a new card with a different issuer. Some issuers allow transfers between their own cards if they are separate accounts, but this is rare and you should confirm before explore.
What if I cannot pay off the balance before the promotional period ends?
The remaining balance will accrue interest at the card's standard rate. You can continue making payments at the regular rate, or you can attempt another balance transfer to a different card with a new promotional period. However, each transfer charges a fee and requires a new process, so this strategy only works if you can pay down the balance over time.
Does a balance transfer hurt my credit score?
A balance transfer involves a hard inquiry and a new account, both of which lower your score slightly in the short term. However, moving debt off one card and onto another reduces your utilization on the old card, which can improve your score over time. The net effect is usually a small temporary dip followed by improvement within a few months.
Can I transfer a balance if I am behind on payments?
Most issuers will not approve a balance transfer if you are currently late on the account you want to transfer from. You need to bring the old account current first. Once it is current, you can explore for a balance transfer card, though your approval odds and promotional terms may be less favorable.
What if the new card issuer denies the transfer request?
The issuer may deny the transfer if the old account is in collections, if you are behind on payments, or if the transfer amount exceeds your credit limit on the new card. Contact the issuer to ask why it was denied. If the reason is a low credit limit, you can request an increase. If the reason is account status, you will need to resolve that issue first.
