Option 1: Balance Transfers (Most Common Legit Tool)
A balance transfer lets you move what you owe on one credit card over to a different credit card. You’re not really “paying” with a card in the everyday sense — you’re shifting the debt.
How a balance transfer works
- You apply for or use an existing Card B that allows balance transfers.
- You ask Card B’s issuer to pay Card A directly for a certain amount.
- Card B then adds that amount to your balance, often with a different interest rate and fee structure.
- Card A shows a payment or payoff, and you now owe that money to Card B instead.
Why people use balance transfers
Common goals include:
- Trying to get a lower interest rate on existing debt
- Combining multiple balances onto a single card
- Getting a temporary promo rate (often advertised for a set number of months)
Whether that actually helps depends on fees, promo terms, and your payoff plan.
Key variables with balance transfers
- Transfer fee: Usually a percentage of the amount you move. This gets added to what you owe.
- Promo interest rate & length: Many offers advertise a temporary low or 0% rate for a certain number of months, then switch to a higher regular rate.
- Which purchases get which rate: New purchases might not get the promo rate and may start accruing regular interest immediately.
- Credit limits: You can only transfer up to your approved limit, often minus the fee.
- Eligibility: Issuers may not let you transfer balances between cards from the same bank.
Who balance transfers can help vs. hurt
Potentially helpful for:
- People who can realistically pay off or pay down a balance within the promo period
- Those with high interest on existing cards who get approved for a meaningfully lower rate
Potentially harmful for:
- People who continue to run up new balances while moving old ones
- Those who only make minimum payments, letting the balance linger past the promo period
- Anyone paying a large fee for a short promo or only slightly better rate
What you’d need to evaluate:
- The total cost of fees + interest on the new card vs. keeping the old debt where it is
- Whether you can stick to a payoff plan during the promo window
- How this will affect your overall credit utilization
Option 2: Cash Advances to Pay Another Card
A cash advance is when you use a credit card to borrow cash or cash-like funds. You can then use that cash to pay another card.
This can look like:
- Taking cash out of an ATM with Card B, then depositing it and using it to pay Card A
- Asking your card issuer for a direct cash advance into your bank account, then paying Card A from there
Why this is expensive
Cash advances are usually one of the costliest ways to borrow on a credit card:
- Cash advance fee: Often a percentage of the amount you take, sometimes with a minimum dollar amount.
- Higher interest rate: Cash advances often have a higher APR than regular purchases.
- No grace period: Interest often starts accruing immediately, not after a statement cycle.
So while you technically used Card B to “pay” Card A, you’ve usually:
- Increased your total cost of borrowing
- Turned a regular balance into a higher-cost cash advance balance
When people still consider cash advances
- Short-term emergencies when there’s no other source of funds
- Situations where they’re trying to avoid a late payment on another card at any cost
What you’d need to evaluate:
- Fees and interest rate on the cash advance
- How quickly you can pay back the advance
- Whether there are any lower-cost options (payment plan, hardship program, personal loan, etc.)
Option 3: Third-Party Apps and Digital Workarounds
Some people try to pay a credit card with another card by going through a payment app, digital wallet, or bill-pay service ���.
Examples of how this can play out:
- Using a payment service that lets you pay bills with a credit card, and it then sends money to your credit card issuer
- Sending money to yourself or a trusted person via an app using Card B, then using that money to pay Card A
Why this is risky or costly
- Fees: Many services charge a percentage fee to fund payments with a credit card.
- Coding as cash advance: Some issuers treat these payments as cash-like or quasi-cash, which can trigger cash advance fees and higher interest.
- Violating terms: Certain “loop” methods (like sending yourself money just to get cash from a card) may violate card or app terms, leading to account limits or closures.
- Unpredictable treatment: How a transaction is coded (purchase vs. cash advance) can vary by service and card issuer.
What you’d need to check:
- The service’s fees and terms
- How your card issuer treats those types of transactions
- Whether you’re comfortable with the rule gray area some methods rely on
Option 4: Convenience Checks From Your Card Issuer
Some credit card companies send “convenience checks” — blank checks tied to your credit card account.
You can sometimes:
- Write a convenience check from Card B and use it to pay Card A
- Deposit the check into your bank account and then pay Card A from there
How issuers typically treat these checks
Depending on the offer and fine print, convenience checks may be treated as:
- A cash advance (with cash advance fees and higher interest), or
- A balance transfer (sometimes with a promo rate and transfer fee)
So while it feels like writing a normal check, it’s really just another borrowing method.
What you’d need to look at:
- Whether the check is labeled as a cash advance or balance transfer
- Any fees, rates, and promo time limits
- How it fits into your overall repayment plan
Why You Might Want to Do This in the First Place
People look for ways to pay a credit card with another card for a few common reasons:
- High interest on a current card and a desire to reduce interest costs
- A temporary cash crunch where other payment sources aren’t available
- Trying to consolidate multiple card balances into fewer accounts
- Wanting more time to pay off what they owe
None of those goals are inherently “bad” — what matters is how you pursue them and what it ultimately costs you.
Key Factors to Weigh Before Using One Card to Pay Another
Everyone’s situation is different, but some general questions can help frame your decision:
1. Total cost, not just “Can I do it?”
- What are the fees (transfer fee, cash advance fee, app fee)?
- What interest rate will apply — and for how long?
- When does a promo rate end, and what rate comes after?
2. Your payoff timeline
- How many months do you expect it will take to pay off or significantly reduce the balance?
- Do you have a plan to avoid adding new charges to either card during that time?
3. Credit limit and utilization
- Will moving or adding debt push your total balances close to your credit limits?
- How might that impact your credit utilization ratio, which is a key part of many credit scores?
4. Simplicity vs. complexity
- Are you making your finances easier to manage, or more tangled?
- Will you be able to track promo deadlines, due dates, and different rates across cards?
5. Alternatives outside of credit cards
Depending on the situation, people sometimes also look into:
- Payment plans or hardship programs with their existing card issuer
- Budget adjustments to free up cash for a period
- Other forms of credit that may have more predictable costs
What’s appropriate depends heavily on your income, other debts, and overall financial picture.
FAQ: Quick Answers to Common Questions
Can I add a credit card as a payment method to pay another card?
In most cases, no. Card issuers typically do not allow one credit card number to be used directly as the payment source for another card’s bill. You usually need a bank account, debit card, or check.
Is using a credit card to pay another card always a bad idea?
Not always. A well-planned balance transfer can reduce interest costs for some people. On the other hand, cash advances or high-fee app workarounds often end up more expensive and can be risky. The impact depends on fees, rates, and your ability to pay down the balance.
Will using one card to pay another hurt my credit score?
It depends how you do it:
- Balance transfers don’t inherently hurt scores, but:
- A new card can lead to a hard inquiry.
- Higher balances relative to limits can raise your utilization ratio, which can weigh on scores.
- Cash advances don’t directly impact the score formula differently, but if they lead to higher balances and minimum-only payments, that can cause issues over time.
The more you’re maxing out limits or carrying large balances, the more likely your scores are to feel the impact.
Can I earn rewards by paying a credit card bill with another card?
If you’re trying to route a payment through a rewards card (for points, miles, or cash back), remember:
- Many apps and services charge fees that can easily outweigh any rewards value.
- Issuers may treat some of these transactions as cash advances, which usually don’t earn rewards and can be costly.
- Even if rewards are earned, paying interest on the new balance often cancels out any benefit.
Bottom Line: What You Control
You usually can’t just plug Card B’s number into Card A’s payment screen, but you can:
- Use balance transfers or convenience checks to move balances, with careful attention to fees, rates, and promo windows
- Use cash advances only with a clear understanding of the higher costs
- Avoid “clever” payment loops that rely on uncertain coding and app rules
The right move, if any, depends on:
- How much you owe and at what rates
- How quickly you can realistically pay it down
- How comfortable you are managing multiple cards and promotions
Once you understand the tools and tradeoffs, you’re in a better position to decide whether using one credit card to handle another is worth the complexity and cost in your own situation.
