The short answer: most credit card issuers will not let you pay your bill with another credit card, and the few that do charge a cash advance fee that makes it expensive.
When you try to pay a credit card balance using another credit card's number, the payment processor treats it as a cash advance rather than a regular purchase. Cash advances come with their own interest rate—often higher than your purchase rate—and start accruing interest immediately, with no grace period. On top of that, you pay an upfront fee, usually 3 to 5 percent of the amount you're moving. So if you transfer $1,000 from one card to another, you might pay $30 to $50 just to make the transfer happen, plus interest starting right away.
Most card issuers block this entirely at the payment processing level. Visa and Mastercard's own rules allow it, but individual banks choose not to accept it. The ones that do allow it—usually through a third-party payment processor or a cash advance at an ATM—are betting you won't notice the fees until they show up on your statement.
Key Takeaways
- Paying one credit card with another credit card is treated as a cash advance, which charges a separate fee (typically 3 to 5 percent) and a higher interest rate with no grace period.
- Most credit card issuers block credit card payments outright, so the transaction may simply be declined at checkout.
- If you need to move money between cards, a balance transfer is cheaper than a cash advance, though it still costs money and affects your credit utilization.
- The cheapest way to pay a credit card bill is with a bank account transfer, debit card, or check—all of which have no fees.
- If you cannot pay your bill, contact your card issuer to discuss a payment plan rather than trying to move debt between cards.
Why card issuers treat it as a cash advance
A cash advance is money you borrow against your credit line, not a purchase. When you use your card at an ATM or request cash from a teller, you are taking a cash advance. When you try to pay a credit card bill with another credit card, the payment processor sees it the same way—you are borrowing money to send money, not buying something.
This distinction matters because cash advances are riskier for the lender. You are not buying a physical good or service; you are just moving money. The card issuer charges more for that risk: a higher interest rate, an upfront fee, and no grace period. Interest starts accruing the day the advance posts, even if you pay it off immediately.
Some card issuers allow cash advances through third-party payment platforms or mobile apps, but they still charge the same fees and interest rates. A few may allow you to pay your bill with another card if you call customer service, but again, it will be processed as a cash advance.
What the fees and interest actually cost
The cash advance fee is usually 3 to 5 percent of the amount transferred. On a $2,000 payment, that is $60 to $100 before interest even starts. The cash advance interest rate is often 2 to 3 percentage points higher than your purchase rate—so if your card charges 18 percent APR on purchases, the cash advance rate might be 21 or 22 percent.
Interest on a cash advance accrues daily from the day it posts, with no grace period. If you transfer $2,000 and pay it back in 30 days, you will owe roughly $110 to $120 in interest alone, plus the $60 to $100 upfront fee. That is $170 to $220 in total cost to move $2,000 between cards—roughly 8.5 to 11 percent of the amount you transferred.
By contrast, a regular credit card payment made by bank transfer, debit card, or check costs nothing. Even a balance transfer, which also costs money, usually charges a one-time fee of 3 to 5 percent with a lower interest rate and a grace period, making it cheaper than a cash advance if you need to move debt.
When a credit card payment will be declined
Most card issuers will simply decline a credit card payment made with another credit card. You will see an error message at checkout saying the transaction cannot be processed. This is not a technical glitch—it is a deliberate block by the card issuer's payment system.
If you try to pay online, by phone, or through the card issuer's app, the system will reject it before it even reaches the cash advance processing stage. Some issuers may allow you to request a cash advance through a different channel (like an ATM or a call to customer service), but paying a bill directly with another card is almost always blocked.
The block exists partly to protect you from accidentally triggering expensive fees, and partly because the card issuer does not want to process cash advances through their bill payment system. It keeps their accounting cleaner and their customer service calls lower.
The better alternatives to move money between cards
If you need to pay one credit card with money from another card, your cheapest option is to withdraw cash from the second card and deposit it into your bank account, then pay the first card from that account. This costs the cash advance fee but avoids the additional credit card payment processing fees. It is still expensive, but it is the most direct route.
A balance transfer is cheaper if you are trying to move an existing balance. You request a balance transfer from one card to another, and the new card pays off the old card's balance. Balance transfers usually charge a 3 to 5 percent fee, but they come with a lower interest rate (sometimes 0 percent for a promotional period) and a grace period. If you have time to plan, this is better than a cash advance.
The cheapest option is to use your bank account. If you have access to a checking or savings account, transfer money from that account to pay your credit card bill. Bank transfers are free and take 1 to 3 business days. If you do not have a bank account, a debit card payment or a check also costs nothing.
What to do if you cannot pay your bill
If you are short on money and cannot pay your credit card bill, do not try to move debt between cards. Instead, contact your card issuer directly and ask about a payment plan or hardship program. Most issuers have programs that let you make smaller payments over time, sometimes with a reduced interest rate.
Tell the issuer your situation honestly: job loss, medical emergency, unexpected expense. Many card companies have formal hardship programs that pause late fees, lower your interest rate, or set up a payment schedule. These programs do not show up on your credit report the same way a missed payment does, and they cost you nothing.
If you miss a payment, the issuer will report it to the credit bureaus after 30 days. After 60 days, you may face a higher interest rate. After 90 days, the account may be sent to collections. Calling before you miss a payment is always better than trying to fix it afterward with expensive workarounds.
How balance transfers work if you need to move debt
A balance transfer lets you move an existing balance from one card to another, usually one with a lower interest rate or a promotional 0 percent APR period. You request the transfer through the new card issuer, and they pay off the old card's balance directly. The old card is then closed or left with a zero balance.
Balance transfers charge a fee—usually 3 to 5 percent—but the fee is added to your new balance, not charged upfront. So if you transfer $5,000, you pay a $150 to $250 fee, but you do not pay it out of pocket. The promotional rate (often 0 percent for 6 to 21 months) means you can pay down the balance without interest accruing during that period.
The catch is that balance transfers count toward your credit utilization on the new card, which can lower your credit score temporarily. Also, if you do not pay off the balance before the promotional period ends, the interest rate jumps to the card's regular rate, which can be high. Read the terms carefully and make sure you have a plan to pay it off before the promo rate expires.
Frequently Asked Questions
What happens if I try to pay my credit card bill with another credit card?
The payment will most likely be declined. If it goes through, it will be processed as a cash advance, which charges a 3 to 5 percent fee upfront and a higher interest rate with no grace period. Interest starts accruing immediately.
Is there any credit card company that lets you pay with another card?
A few issuers may allow it through a third-party payment platform or by calling customer service, but it will still be treated as a cash advance with all the associated fees and interest. It is not worth the cost.
Can I use a debit card to pay my credit card bill?
Yes, and it costs nothing. Debit card payments are processed like any other bill payment and do not trigger cash advance fees. Most card issuers accept debit card payments online, by phone, or through their app.
Is a balance transfer cheaper than a cash advance?
Yes. A balance transfer charges a one-time fee of 3 to 5 percent but usually comes with a lower interest rate and a grace period. A cash advance charges the same upfront fee but with a higher interest rate and no grace period, making it more expensive over time.
What should I do if I cannot afford to pay my credit card bill?
Call your card issuer and ask about a payment plan or hardship program. Most issuers have programs that let you make smaller payments, sometimes with a reduced interest rate. This is free and better than missing a payment or trying expensive workarounds.
