How do credit cards work?
You can spend money on a credit card up to a defined limit set by the credit card provider. You use a credit card in just the same way you would a debit card, to buy things and pay bills – the main difference is that with a credit card you’re borrowing the money you spend from the card provider rather than using money from your own bank account.
If you pay your balance off in full and on time every month, you usually won’t have to pay any interest. If you can’t pay it off in full each month, it’s important to at least make the minimum repayment as missing even one payment can cost you more in charges and negatively affect your credit score.
When applying for a credit card, keep an eye on the annual percentage rate (APR). Credit cards are advertised with an APR that represents the total annual cost of the credit, including interest and fees.
