You can transfer a balance to another card, but you cannot simply swipe one card to pay another

Credit card companies do not let you use one card to pay the balance on another card directly — you cannot walk into a store, use Card A to buy a payment on Card B, or call your issuer and charge the payment to a different card. The payment system treats credit card payments as transfers of money, not purchases, so they fall outside the normal card network rules.

What you can do is move the debt itself from one card to another through a balance transfer, or pay off Card B using cash or a bank transfer funded by Card A. The route you choose depends on whether you want to move the debt, pay it down with borrowed money, or use a different card's rewards.

Key Takeaways

  • A balance transfer moves your debt from one card to another and often comes with a lower interest rate for a set period, but includes a one-time transfer fee of 3% to 5% of the amount moved.
  • You can use a cash advance from one card to pay off another card's balance, but cash advances charge higher interest rates and fees than regular purchases.
  • Some cards let you transfer money to a linked bank account, which you can then use to pay any other card — this avoids the cash advance label but still costs money.
  • Balance transfers work best when you plan to pay down the debt during the promotional period, because the regular interest rate after that period ends is often higher than your original card's rate.
  • Paying off debt with another card's rewards or cash back is possible only if you first convert that card's rewards into a statement credit or deposit the cash back to a bank account.

How a balance transfer works and what it costs

A balance transfer moves your balance from Card B to Card A, usually with a promotional interest rate — often 0% APR for 6 to 21 months, depending on the card and the offer. During that period, you pay no interest on the transferred amount, which can save hundreds of dollars if you pay down the balance steadily.

The catch is the balance transfer fee, charged upfront and added to your new balance. This fee is typically 3% to 5% of the amount transferred — so moving a $5,000 balance costs $150 to $250 immediately. Some cards waive the fee for transfers completed within the first 60 or 90 days of opening the account, so timing matters.

After the promotional period ends, the regular APR kicks in. This rate is often higher than the APR on your original card, so a balance transfer only saves money if you pay down most or all of the balance before the offer expires. If you still owe $2,000 when the 0% period ends, you will pay the card's standard APR on that remaining balance going forward.

Using a cash advance to pay another card

A cash advance lets you borrow money against your credit limit and deposit it into a bank account. You can then transfer that money to pay off another card's balance. This works, but it is expensive: cash advances charge a separate fee (usually 3% to 5% of the amount) and a higher interest rate than purchases — often 25% to 30% APR with no grace period.

Interest on a cash advance starts accruing immediately, even if you pay it back the next day. So if you take a $5,000 cash advance at 28% APR and pay it back in 30 days, you will owe roughly $116 in interest alone, plus the upfront fee. This approach makes sense only if you need the money for a true emergency and plan to pay it back within days.

Some cards offer a lower cash advance APR as part of a promotional offer, similar to a balance transfer. Check your card's terms or call the issuer to see whether a promotional cash advance rate is available before you proceed.

Moving money through a bank account transfer

Many cards let you request a transfer of funds to a linked bank account — sometimes called a "convenience check" or a direct bank transfer. This money lands in your account as a regular deposit, and you can then use it to pay any bill, including another credit card balance.

This route avoids the "cash advance" label, but the cost structure is similar: you pay a fee (usually 2% to 3%) and a promotional or standard APR. The advantage is that you have the money in your bank account, so you can time the payment to your other card however you want, and you are not locked into paying the issuer directly.

The disadvantage is that this money is still a loan against your credit limit, so it counts toward your utilization and affects your credit score the same way a cash advance does. Use this method only if the fee and interest rate are lower than the APR you are currently paying on the other card.

Paying with rewards or cash back from another card

If Card A has a large rewards or cash back balance, you can convert those rewards into a statement credit (which reduces your balance on Card A) or deposit the cash back into a bank account. You can then use that bank account money to pay Card B. This is not borrowing — you are using money you have already earned — so there is no fee or interest.

The limitation is that most cards do not let you convert rewards directly into a payment to another card. You have to go through the intermediate step of converting to a statement credit or bank deposit first. Check your rewards program's rules to see what options are available.

This approach works best if you have accumulated a large rewards balance and want to use it to pay down high-interest debt on another card. It costs nothing and does not add to your debt, so it is worth exploring before you consider a balance transfer or cash advance.

When a balance transfer makes financial sense

A balance transfer saves money only if the fee and the interest you avoid during the promotional period add up to less than the interest you would pay on the original card. Here is a simple comparison: if you owe $5,000 on Card B at 22% APR and you transfer it to Card A with a 0% APR for 12 months and a 3% fee, you pay $150 upfront but avoid $1,100 in interest over the year — a net savings of $950.

But if you only pay down $1,000 of that balance during the 12 months and still owe $4,000 when the promotional period ends, and Card A's regular APR is 24%, you will pay more interest on the remaining balance than you would have on the original card. The math only works if you commit to paying down the balance aggressively during the promotional window.

A balance transfer also makes sense if you are consolidating multiple cards into one, because you simplify your payments and focus your effort on a single deadline. Just make sure you do not rack up new balances on the cards you transferred from — that defeats the purpose.

What happens to your credit score

A balance transfer or cash advance will temporarily lower your credit score because it increases your credit utilization (the amount of your available credit you are using) and triggers a hard inquiry. The utilization hit is usually the bigger factor: if you transfer a $5,000 balance to a card with a $10,000 limit, your utilization on that card jumps to 50%, which can drop your score by 10 to 20 points.

The score typically recovers within a few months as you pay down the balance. A hard inquiry stays on your report for about a year but has less impact over time. If you are planning to apply for a mortgage or car loan soon, a balance transfer might not be the right move because the timing could hurt your approval odds.

Frequently Asked Questions

Can I use one credit card to pay another card's minimum payment?

No, you cannot swipe one card to pay another card's bill directly. You would need to use a cash advance or balance transfer to move money, or pay the bill through your bank using the card's routing and account number as the source of funds — but that is not possible either, because banks do not accept credit card accounts as payment sources for other credit card bills.

What if I do not pay off the balance transfer before the promotional period ends?

The remaining balance will be charged the card's regular APR, which is often higher than your original card's rate. You will owe interest on that remaining balance going forward. If you cannot pay it off during the promotional period, a balance transfer may not save you money overall.

Is a balance transfer the same as a debt consolidation loan?

No. A balance transfer moves debt between credit cards and usually comes with a promotional interest rate. A debt consolidation loan is a separate loan from a bank or lender that pays off multiple debts at once. A consolidation loan has a fixed term and fixed payment, while a balance transfer has a promotional period after which the regular APR applies.

Can I transfer a balance to a card from the same issuer?

Most issuers allow transfers between their own cards, but some restrict it. Check your card's terms or call the issuer to confirm. Even if allowed, the fee and promotional rate apply the same way as a transfer to a different issuer's card.

How long does a balance transfer take to show up on the new card?

Most balance transfers complete within 7 to 14 days, though some take up to 21 days. During that time, you are still responsible for payments on the original card. Do not skip a payment on Card B while waiting for the transfer to post, because missed payments damage your credit score and trigger late fees.
