Five things to know before you use a credit card
Not how to pick one. How to use one, so that the first year builds something rather than costing you.
A credit card is a genuinely useful instrument and an expensive one, depending entirely on how it is used. The difference between the two outcomes comes down to a handful of things that nobody explains when the card arrives.
1. The minimum payment is a trap, not an option
The statement shows a total due and a minimum due, usually a small fraction of the balance. Paying the minimum keeps your account in good standing, which is why it feels safe. It is not.
The moment you pay less than the full amount, interest begins on the entire outstanding balance, and often on new purchases from the day you make them rather than from the statement date. Credit card interest rates are among the highest of any consumer credit product.
The minimum due is the amount that keeps the lender happy. The total due is the amount that keeps the card free.
2. The interest-free period only exists if you clear the balance
Cards advertise an interest-free window of up to fifty days or so. That window is real, but conditional. It applies only when you pay the statement in full by the due date. Carry a balance once and the interest-free period effectively disappears until you clear it completely.
3. How much of the limit you use is being watched
The share of your limit you actually use is one of the more heavily weighted parts of a credit score. Someone who spends forty thousand on a fifty thousand limit looks stretched, even if they pay it in full every month.
4. Cash withdrawal is a different product
Taking cash out of an ATM with a credit card is not a purchase. There is typically a fee straight away, and interest starts from the day of withdrawal with no interest-free period at all.
Worth knowing
If you are in a position where withdrawing cash on a credit card feels necessary, almost any other option is cheaper. It is worth knowing that before the moment arrives.
