You can pay a credit card with another card, but the issuer will treat it as a cash advance, not a regular purchase
When you use one credit card to pay the balance on another card, the card you're charging to will classify the transaction as a cash advance. This matters because cash advances carry different terms than regular purchases: a higher interest rate (often 3 to 5 percentage points above your purchase APR), an upfront fee (typically 3 to 5 percent of the amount), and interest that starts accruing immediately with no grace period.
The practical result is that paying Card A with Card B costs you money right away and then costs you more money every day the balance sits unpaid. You're not solving a debt problem; you're converting one debt into a more expensive debt.
There are narrow situations where this makes sense—usually when you're buying time for a specific reason and the math works out. Most of the time, it doesn't.
Key Takeaways
- Paying a credit card with another credit card triggers a cash advance classification, which charges an upfront fee of 3 to 5 percent plus a higher interest rate with no grace period.
- You can pay a credit card bill using a debit card, bank transfer, or check without triggering cash advance fees, and these are the standard payment methods issuers expect.
- Balance transfer cards offer a structured alternative if you're moving debt between cards, with a one-time transfer fee but a 0 percent introductory APR period that can last 6 to 21 months.
- If you're short on cash, contacting your card issuer about a hardship program or payment plan is cheaper than a cash advance, because those programs often reduce or pause interest.
How credit card issuers process card-to-card payments
When you attempt to pay a credit card bill using another credit card, you're not actually sending money from one card to another. Instead, you're using the second card to take out cash (or a cash-like transaction) that you then send to the first card's issuer.
The card you're charging to sees this as a cash advance request. It pulls funds from your available credit, charges you the cash advance fee immediately, and assigns the transaction a cash advance APR. That APR applies from day one—there is no 21-day grace period like there is for purchases.
Some payment processors (like Plastiq or third-party bill-pay services) will accept a credit card as payment for bills, but they're still processing it as a cash advance on the back end, and they add their own fee on top of the card issuer's fee. You end up paying two fees instead of one.
When the math actually works
Card-to-card payments are expensive enough that you need a specific reason for them to make financial sense. The main scenario is when you're buying time before a large payment arrives—a tax refund, a bonus, a reimbursement—and the interest you'll pay over those weeks is less than the cost of missing a payment or overdrafting.
Example: You owe $2,000 on Card A, due in 5 days. You don't have the cash yet, but you're expecting a $3,000 reimbursement in 10 days. Using Card B to pay Card A costs you a $100 cash advance fee (5 percent) plus roughly $8 in interest for the 10 days the balance sits. Total cost: $108. Missing the payment on Card A would cost you a $35 late fee plus damage to your credit score. In this narrow window, the cash advance is the cheaper option.
Most situations don't line up this way. If you're using a cash advance to cover regular expenses or to buy time indefinitely, you're in a debt spiral, not a temporary fix.
Better ways to pay a credit card bill
Your card issuer expects you to pay using a debit card, bank account transfer, or check. These methods cost nothing and don't trigger cash advance fees. You can set them up through your card's online portal or by phone with customer service.
If you don't have funds available right now, a balance transfer card is a structured alternative to a cash advance. You transfer the balance from Card A to a new Card B that offers a 0 percent introductory APR period (typically 6 to 21 months, depending on the card and your creditworthiness). You pay a one-time balance transfer fee of 3 to 5 percent, but then you have months to pay down the balance interest-free. This is more expensive upfront than a regular payment, but far cheaper than a cash advance if you need time.
Balance transfers work best when you're consolidating multiple cards or moving debt to a card with better terms. They require an approval process and a credit check, so they're not instant—plan for 5 to 7 business days for the transfer to post.
What to do if you can't pay right now
If you're short on cash and a payment is due soon, contact your card issuer before you miss the payment. Most issuers have hardship programs that can lower your interest rate, pause interest temporarily, or set up a payment plan. These programs won't appear on your credit report the way a missed payment will, and they cost nothing to request.
Explain your situation clearly: job loss, medical emergency, temporary income reduction. Be specific about when you expect to have funds available. The issuer's goal is to get paid eventually, so they're often willing to work with you if you reach out first.
If hardship programs don't apply to your situation, ask about a one-time courtesy late fee waiver or a reduced payment option. You won't know what's available unless you ask.
The credit score impact of different payment methods
A cash advance doesn't directly hurt your credit score the way a missed payment does, but it does increase your credit utilization ratio (the amount of available credit you're using). If you take a $2,000 cash advance on a card with a $5,000 limit, your utilization jumps to 40 percent, which can lower your score by 10 to 50 points depending on your overall credit profile.
A missed payment, by contrast, stays on your credit report for seven years and can lower your score by 100 points or more. So a cash advance is still preferable to missing a payment, but only barely.
A balance transfer also increases utilization, but the 0 percent APR period gives you time to pay it down without interest charges piling up. If you pay down the balance during the promotional period, the utilization impact is temporary.
Fees and interest rates you'll actually pay
Cash advance fees vary by card and issuer, but they're typically 3 to 5 percent of the amount you're advancing. On a $1,000 cash advance, that's $30 to $50 upfront.
Cash advance APRs also vary. Some cards charge 18 to 22 percent; others charge 25 to 29 percent. Check your card's terms document (called the Schumer Box, found on your issuer's website or in your welcome materials) to see your specific rates. The APR applies from the transaction date, not from a statement closing date.
If you carry the cash advance for 30 days at 22 percent APR, you'll pay roughly $18 in interest on a $1,000 advance. Add the $30 to $50 fee, and your total cost is $48 to $68 for one month. That compounds quickly if you can't pay it off.
Frequently Asked Questions
Can I use a credit card to pay another credit card through my bank's bill-pay system?
Most banks' bill-pay systems won't accept a credit card as a payment method—they're designed for checking account transfers. If you try to enter a credit card number, the system will reject it or flag it as a cash advance. Check with your bank, but assume the answer is no.
What if I use a rewards card to pay another card—do I earn points on the cash advance?
No. Cash advances don't earn rewards points, even on cards that earn points on all other transactions. You pay the fee and the high interest rate with no upside. This is another reason cash advances are a bad deal.
Is paying a credit card with a debit card the same as a cash advance?
No. A debit card payment is a regular payment that comes directly from your bank account. It's not classified as a cash advance, carries no fee, and doesn't trigger any special interest rate. This is the standard way to pay a credit card bill.
Can I transfer a balance to a card I just opened?
Yes, but timing matters. Most issuers allow balance transfers within the first 60 days of opening the account. After that window closes, you can't transfer a balance to that card anymore. If you're planning a balance transfer, do it early.
What happens if I can't pay off a cash advance before interest kicks in?
The interest accrues daily at your cash advance APR until the balance is paid in full. Payments go toward your lowest-APR balance first (usually purchases), so the cash advance sits and grows. This is why cash advances are a debt trap—they're expensive and they're hard to pay off quickly.
