How Does Credit Cards vs Debit Cards (And When to Use Them) Work?

A credit card is like having a piggy bank that your friend lends you money from, while a debit card is like using your own piggy bank directly.

When you use a credit card, it's like borrowing money from a friend to buy something today. You promise to pay them back later, maybe with some extra candy as a thank-you. That’s why you get bills every month. If you don’t pay them back on time, your friend might send a reminder (or even a tiny time-out).

When you use a debit card, it's like taking money straight from your piggy bank to buy something right away. You don’t owe anyone anything, you just have less candy in your piggy bank.

• Use a credit card when you want to buy something big today but plan to pay for it later, like a toy that costs more than your whole piggy bank.
• Use a debit card when you want to buy something right now and don’t mind using some of your savings, like buying ice cream with the money you saved from not eating candy all week.
