Usually, no — at least not directly. Most credit card companies won't allow you to punch in the numbers for another credit card to pay your bill. The main reason why it's typically not an option is that the processing fees are too high for the company. However, if the due date on your credit card bill is fast-approaching and you don't have the cash, you can find another way to use a second credit card or try another approach.
If you have a second credit card, you can take a cash advance against it to pay off the first credit card, or at least pay the monthly bill. You can then deposit the cash into your bank account and make your payment. However, there is a drawback to cash advances: the fees. It's not uncommon for a fee to be 5 percent or $10 — whichever is higher. There are also limits to how much you can get. Usually, the limit is lower than a credit limit, so if you're in considerable debt, a cash advance likely won't cover it.
Do you have several lines of credit that you're struggling to keep current every month? If so, consider credit card debt consolidation. For example, taking out a personal loan can help you manage your debts and reduce your monthly payments to one credit bill — that is, your loan repayment. This is a great option, as long as you make your payments on time and can snag a loan with reasonable rates and terms.
Re-Evaluate Your Spending
If you've found yourself in this position before, it's probably a good time to ask yourself, "Why am I overspending and on what?" Review your credit card purchase history and figure out why you're overspending in the first place. Create a monthly budget for yourself and avoid wasting money or credit on purchases that aren't necessary. You can also speak with a credit counselor if you're unsure about your next steps. Make sure the agency you contact is accredited by the National Foundation for Credit Counseling.
