Credit Cards and Debt
Borrowing costs interest, so manage debt carefully.
About this topic
Credit lets you borrow now and repay later, but it costs money. Credit cards charge high interest, often 20 percent or more APR, on unpaid balances; paying only the minimum keeps you in debt for years while interest compounds. Good practice: pay the full balance on time, borrow only what you can repay, and keep track of the interest rate and fees.
Debt matters because it can be a useful tool, such as a mortgage or student loan that raises future income, or a trap when used for spending beyond means. Your credit score summarises how reliably you repay and affects the rates you are offered, and even job or housing applications. Late payments and high balances lower it, while on-time payments raise it.
Example: a 1,000 dollar balance at 20 percent APR with only the minimum payment of about 25 dollars a month can take over five years to clear and cost hundreds in interest. Paying the full amount each month costs nothing in interest. Compare this with a student loan at a low rate that increases lifetime earnings, which is considered good debt.
Misconceptions: carrying a balance does not improve your credit score, and a card is not extra income. Tip: treat a credit card like a debit card, spending only money you already have.
