Credit Cards Are Not Free Money

The plain answer

Section titled “The plain answer”

A credit card does not increase your income. Every purchase becomes debt that you must repay. The credit limit shows how much the issuer will lend you, not how much you can afford to spend.

How it actually works

Section titled “How it actually works”

When you use a credit card, the issuer pays the merchant and adds the purchase to your balance. You later repay the issuer. If you carry a balance, interest can make the purchase cost more than its original price.

What this means for you

Section titled “What this means for you”

Before using a card, check that you already have room for the purchase in your budget. Track card purchases like spending from your checking account, even though the cash leaves later.

Common mistakes

Section titled “Common mistakes”

Confusing available credit with available cash. Using a card to cover regular expenses that income cannot support. Assuming future income will make repayment easy.
