Credit Cards
Used well, a credit card is a free short-term loan plus rewards. Used poorly, it is one of the most expensive ways to borrow money. The difference is whether you carry a balance.
Typical APR
18% to 29%
Grace period
About 21 to 25 days
Annual fees
$0 to $695
Best use
Pay in full, every month
Figures above are typical ranges for general guidance only. Your actual rate and terms depend on your credit, income, and lender, and change over time. Confirm current numbers directly with a lender.
A credit card is revolving credit: you have a limit, you borrow against it, and you can carry the balance from month to month. The crucial feature is the grace period. If you pay your statement balance in full by the due date, you pay zero interest on purchases. That is what makes a rewards card a genuinely free tool. The moment you carry a balance, the grace period disappears and the high APR takes over, which usually wipes out any rewards you earned.
Choosing a card comes down to your habits. If you pay in full every month, chase the rewards that match your actual spending, whether that is cash back on groceries and gas or travel points. If you sometimes carry a balance, a low-rate card or a balance-transfer offer matters far more than rewards. And if you are building or rebuilding credit, a secured card or a starter card is the on-ramp.
The most damaging mistake is treating the minimum payment as the bill. Paying only the minimum on a typical balance can take well over a decade to clear and cost more in interest than the original purchases. If you can only make the minimum, that is a signal to stop charging and make a payoff plan, not a sustainable way to use the card.
When it makes sense
- You pay your statement balance in full and want rewards on spending you already do.
- You are building or rebuilding credit and want a simple, low-risk starter card.
- You want to consolidate card debt with a 0% balance-transfer offer and a payoff plan.
What to watch for
- Carrying a balance erases your rewards and triggers a high APR with no grace period.
- Paying only the minimum can stretch a balance into a decade of payments.
- Annual fees only pay off if your rewards clearly exceed them.

6 min readFrequently asked questions
Do credit cards charge interest if I pay in full?
No. As long as you pay your full statement balance by the due date each month, you pay no interest on purchases thanks to the grace period. Interest only kicks in when you carry a balance forward.
How do I choose a credit card?
Start with your habits. If you pay in full, pick rewards that match your spending. If you carry a balance, prioritize a low APR or a balance-transfer offer over rewards. If you are building credit, a secured or starter card is the place to begin.
Will paying only the minimum hurt me?
It will not hurt your credit if you pay on time, but it is very expensive. Minimum payments are mostly interest, so a balance can take more than a decade to clear and cost more than what you bought. Pay as much above the minimum as you can.
