The short answer: almost never directly, but a few workarounds exist
You cannot walk into a payment portal and swipe one credit card to pay another credit card's bill. The card networks and banks have built systems that block this because it would let people borrow indefinitely without ever paying down debt. But there are three real paths people use when they are stuck: a balance transfer, a cash advance, or paying with a debit card funded by a credit card advance.
Each one costs money and carries different traps. The trap you fall into depends on which method you choose and how quickly you move.
Key Takeaways
- Direct credit card to credit card payments are blocked by the card networks, so you cannot straightforward use one card to pay another card's bill online or by phone.
- A balance transfer moves your debt from one card to another, usually at a lower rate for a set period, but charges a fee upfront (typically 3 to 5 percent of the amount transferred).
- A cash advance lets you withdraw money from a credit card's cash line, but charges a fee and a higher interest rate than regular purchases, and interest starts accruing when ready with no grace period.
- Paying with a debit card funded by a credit card cash advance is the slowest route and stacks fees on top of each other, making it the most expensive option.
- If you are behind on a payment, contact your card issuer directly — many offer hardship programs, payment plans, or temporary rate reductions that cost far less than any workaround.
Why the payment systems block card-to-card payments
Credit card networks (Visa, Mastercard, American Express, Discover) and the banks that issue cards treat a credit card payment as a balance reduction, not a purchase. When you pay your bill, you are reducing what you owe. If you could pay with another credit card, you would be moving debt from one card to another without actually paying anything down — you would just be borrowing more to cover the old borrowing.
The networks prevent this at the system level. When you try to enter a credit card number as payment, the processor rejects it before it ever reaches the card issuer. Debit cards, bank account transfers, and checks go through because they represent actual money leaving your account. A credit card number does not.
This rule exists to protect both the card companies (who would face massive defaults) and you (who would end up in a debt spiral). It is one of the few rules that actually works in your favor.
Balance transfers: moving debt at a lower rate
A balance transfer is the most common workaround. You open a new credit card (or use an existing one with available credit) and request a balance transfer from your current card. The new card's issuer pays off your old card's balance, and you now owe the new card instead.
The appeal is the rate: many balance transfer cards offer 0 percent interest for 6 to 21 months, depending on the card and your credit. If you can pay down the balance during that window, you save hundreds or thousands in interest. But there is an upfront cost: a balance transfer fee, usually 3 to 5 percent of the amount you transfer. On a $5,000 transfer, that is $150 to $250 added to what you owe before you make a single payment.
The trap is the expiration date. When the 0 percent period ends, the interest rate jumps to the card's regular rate — often 18 to 25 percent. If you still carry a balance, you will owe interest on whatever remains. Many people transfer a balance, feel relief, and then carry the balance past the promotional period without realizing it.
A balance transfer makes sense only if you have a concrete plan to pay down the balance before the promotional period ends. If you cannot do that, the fee and the eventual interest rate make it worse than your current situation.
Cash advances: expensive and when ready interest
A cash advance is withdrawing money from your credit card's cash line — usually at an ATM or through your bank. You then use that cash to pay your other card's bill. This works, but it is the most expensive option.
A cash advance charges three separate costs: a cash advance fee (usually 3 to 5 percent, sometimes a flat amount like $10), a higher interest rate than your regular purchases (often 25 to 30 percent), and no grace period. Interest on a cash advance starts accruing the day you withdraw it, even if you pay it back when ready. On a regular purchase, you get 21 to 25 days before interest kicks in. On a cash advance, you get zero days.
The math is brutal. A $2,000 cash advance at 5 percent fee plus 28 percent interest costs you $100 upfront and then $46 in interest after one month if you do not pay it back. If you carry it for three months, you are paying roughly $200 in interest alone.
Use a cash advance only if you are in a genuine emergency and can pay it back within days, not weeks.
Paying with a debit card funded by a cash advance
Some people try to split the difference: take a cash advance from one card, deposit it into a checking account, and then pay their other card with a debit card. This technically works, but it combines the worst parts of both methods.
You pay the cash advance fee and interest rate on the full amount, plus you lose time. The cash advance hits your credit card when ready, but the deposit into your checking account may take a day, and the debit card payment may take another day to post. During that time, you are paying interest on the cash advance while your original card is still accruing late fees if you were behind.
This route is slower and more expensive than either a balance transfer or a direct cash advance. Avoid it.
What to do if you cannot pay your bill
If you are behind on a payment or cannot pay the full balance, do not reach for a workaround. Call your card issuer directly and explain your situation. Most major issuers have hardship programs that can reduce your interest rate, pause late fees, or set up a payment plan — all without the fees and interest of a balance transfer or cash advance.
These programs are not advertised, and you have to ask for them. The person who answers the phone may not mention them unless you say you are struggling. Be direct: "I am having trouble paying this balance. What options do you have for customers in my situation?" They may offer a temporary rate reduction, a lower monthly payment spread over time, or a freeze on late fees while you catch up.
A hardship program costs you nothing upfront and usually saves you more money than any balance transfer or cash advance. It also does not require a new credit card or a hard inquiry into your credit.
Frequently Asked Questions
Will paying one credit card with another hurt my credit score?
You cannot do it directly, so there is no impact from the payment itself. But a balance transfer or cash advance will trigger a hard inquiry (small, temporary hit) and increase your overall debt temporarily. Your score may dip 5 to 10 points initially, but it usually recovers within a few months if you pay on time.
Can I use a credit card to pay my bill through a third-party payment app?
Most payment apps (Venmo, PayPal, Square Cash) also block credit card payments to other people's credit card bills. Some apps allow credit card funding for peer-to-peer transfers, but the recipient cannot then use that money to pay a credit card bill — the same network rules explore. Check your app's terms, but expect it to be blocked.
What if I have a 0 percent balance transfer offer but I am not sure I can pay it off in time?
Do the math first. Calculate what you owe, divide by the number of months in the promotional period, and see if that monthly payment fits your budget. If it does not, the balance transfer will cost you more than staying put. A 3 percent fee on $5,000 is $150 — you have to save more than $150 in interest during the promotional period just to break even.
Is there a way to pay a credit card bill with another card without a fee?
No. A balance transfer charges a fee upfront. A cash advance charges a fee and interest from day one. There is no fee-free way to move debt from one card to another. If someone claims otherwise, they are selling a scam.
What happens if I ignore the bill and do not pay it?
Late fees start after 30 days, your interest rate may increase, and the missed payment reports to the credit bureaus after 30 days, damaging your score. After 180 days of non-payment, the card issuer typically closes the account and may sell the debt to a collection agency. Call your issuer before you miss a payment — hardship programs exist specifically to prevent this.
