The golden rule of credit card usage is to do everything you can to pay off your entire balance each month. If you can do this, you won't be charged any interest. You'll be enjoying free credit and all the other benefits your card offers. Be sure to always make at least the minimum payment on your card.

The "Golden Rule" of credit cards is to pay your balance in full and on time every single month. Credit cards are incredibly powerful financial tools when used as a "payment method," but they become dangerously expensive when used as a "loan." By paying the full statement balance before the due date, you avoid paying a single cent in interest, effectively getting an interest-free loan for 30 days while earning rewards like cash back or travel points. If you carry even a small balance over to the next month, the "Grace Period" vanishes, and the high APR (often 20% to 30% in 2026) will be applied to your entire balance, quickly negating the value of any rewards you've earned. Additionally, maintaining a perfect payment history is the #1 factor in your credit score. Following this rule ensures you are the one "gaming" the credit card company for perks, rather than the company profiting off your debt. If you cannot afford to pay for an item in cash today, the Golden Rule dictates that you should not put it on a credit card.
