The short answer: you cannot pay a credit card bill using another credit card directly
Most credit card companies will not let you make a payment from another credit card account. When you log into your card's payment portal or call the customer service number, the system only accepts bank account transfers, checks, or money orders — not another card's number.
This rule exists because credit card payments are considered cash advances when they come from another card, and cash advances carry steep fees and higher interest rates. The card issuer treats it as a loan against your credit line rather than a regular purchase. Even if a payment method technically processes, you will pay for it.
If you are trying to move debt from one card to another, there are real options that cost less. If you need to pay a bill and only have access to a credit card, there are workarounds — but they all have costs you should understand first.
Key Takeaways
- Credit card issuers block direct card-to-card payments because they would count as cash advances, which carry fees of 3 to 5 percent plus higher interest rates.
- A balance transfer moves debt between cards at a lower rate, usually 0 percent for 6 to 21 months, but requires you to open a new card and pay a one-time transfer fee of 3 to 5 percent.
- If you need cash to pay a bill, a personal loan from a bank or credit union costs less than a credit card cash advance.
- Paying with a third-party payment service like PayPal or Square Cash adds another fee layer and still counts as a cash advance on many cards.
Why credit card companies block card-to-card payments
When you use one credit card to pay another credit card's bill, the issuer classifies it as a cash advance. A cash advance is not a purchase — it is borrowing money against your available credit, similar to withdrawing cash from an ATM using your card.
Cash advances come with their own pricing structure, separate from your regular purchase rate. Most cards charge a cash advance fee of 3 to 5 percent of the amount, charged when ready. On top of that, the interest rate on cash advances is usually 5 to 10 percentage points higher than your purchase APR, and interest starts accruing right away — there is no grace period like there is for purchases.
Because of these costs, credit card companies have little incentive to make card-to-card payments straightforward. They profit more when you use their card to buy things than when you use it to borrow cash. The payment system is designed to prevent this route entirely.
What happens if you try to pay with a credit card number
If you enter another credit card number into a payment portal, one of three things will happen. Most commonly, the system will reject it outright and show an error message. Some payment systems will accept it but flag it as a cash advance, charging you the fee and higher rate when ready. A small number of older or less sophisticated payment systems might process it as a regular transaction, but the card issuer will reclassify it as a cash advance within a day or two and add the fees retroactively.
The safest assumption is that it will not work, and if it does, it will cost you. Do not rely on this as a payment method.
Balance transfers: moving debt between cards at a lower rate
A balance transfer is a legitimate way to move debt from one card to another, and it costs far less than a cash advance. With a balance transfer, you open a new credit card and request that the issuer pay off your old card's balance directly. The new card charges a one-time transfer fee (usually 3 to 5 percent) but then offers a promotional period — often 0 percent interest for 6 to 21 months, depending on the card and your credit score.
This works because the new issuer is paying the old issuer directly, card-to-card, which is allowed. You are not making the payment yourself; the card company is. You then owe the new card instead of the old one, at a much lower rate.
Balance transfers make sense if you have a large balance and can pay it down during the promotional period. The transfer fee is a one-time cost, but the interest savings over 12 to 18 months usually outweigh it. However, if you only need to move a small amount or if your credit score is low (which would disqualify you from the best promotional offers), the fee might not be worth it.
Using a third-party payment service to pay your credit card
Services like PayPal, Square Cash, Venmo, and Google Pay let you link a credit card and send money to another person or business. Some people try to use these services to pay their credit card bill by sending money to themselves or a family member, who then pays the card. This is a workaround, not a solution.
First, most of these services charge a fee to process a credit card payment — typically 2 to 3 percent. Second, the credit card issuer often still classifies the transaction as a cash advance because money is moving from your credit line to your bank account, even if it goes through a middleman. Third, you are adding an extra step and an extra fee for no real benefit.
If you need to move money from a credit card to pay a bill, a personal loan is cheaper. If you need to pay a credit card bill and only have another credit card available, call the card issuer and ask about payment plan options before you try a workaround.
Personal loans as an alternative to credit card cash advances
If you need cash and only have credit cards available, a personal loan from a bank, credit union, or online lender costs significantly less than a credit card cash advance. Personal loans have fixed interest rates (usually 6 to 36 percent, depending on your credit score and the lender) and no cash advance fees. The interest rate is lower than a credit card's cash advance rate, and you know exactly what you will pay each month.
Credit unions often offer the lowest rates, especially if you have been a member for a while. Online lenders like SoFi, LendingClub, and Upstart approve and fund loans quickly — sometimes within one business day. Banks take longer but may offer better rates if you have an existing relationship with them.
A personal loan also does not count against your available credit the way a cash advance does. When you take a cash advance, it reduces your available credit when ready, which can hurt your credit score. A personal loan is a separate account, so it does not affect your credit utilization ratio on your cards.
When you might need to use a credit card for an emergency
If you are in a situation where you only have access to a credit card and need to pay a bill, your best move is to contact the company you owe money to and explain the situation. Many utilities, medical offices, and other service providers will accept a credit card payment directly, which counts as a regular purchase, not a cash advance. You avoid the cash advance fee and rate this way.
If the bill cannot be paid with a credit card, call your credit card issuer's customer service line and ask about hardship options. Many issuers offer temporary payment plans, lower interest rates, or fee waivers if you explain that you are facing a temporary cash flow problem. This is better than taking a cash advance or using a workaround.
Frequently Asked Questions
Can I use a debit card to pay my credit card bill?
Yes. Debit card payments are treated as regular bank transfers and do not trigger cash advance fees or rates. You can enter your debit card number into most credit card payment portals without any penalty. The payment comes directly from your bank account, so make sure you have the funds available.
What if I pay my credit card with another card and then dispute it?
Disputing the transaction will not remove the cash advance fee or rate. The card issuer will see the dispute, investigate, and confirm that the transaction was processed as authorized. You will still owe the fee and the higher interest rate. Disputing is not a way around the cash advance structure.
Does a balance transfer hurt my credit score?
A balance transfer can temporarily lower your score because it involves a hard inquiry and opens a new account. However, if you pay down the balance during the promotional period, your score will recover and likely improve. The long-term benefit of paying less interest usually outweighs the short-term score dip.
Can I use a rewards credit card to pay another card and earn points?
Most credit card issuers do not allow you to earn rewards on payments to other cards, even if the payment somehow processes. Even if you could earn points, the cash advance fee and interest rate would cost far more than any rewards are worth. This is not a profitable strategy.
What is the difference between a cash advance and a balance transfer?
A cash advance is when you borrow money against your credit line and pay it back with interest and fees. A balance transfer is when a new card issuer pays off your old card's balance, and you owe the new issuer instead. Balance transfers have a one-time fee but a lower promotional rate. Cash advances have ongoing high interest and when ready fees.
