How does credit-card interest work?

Understand daily and monthly interest concepts, statement balances, grace periods, APR, payment timing, and why carrying a balance can increase total cost.

The short answer

Understand the system before choosing an action.

Credit-card interest is generally the cost charged when applicable balances remain unpaid under the account agreement. The calculation may involve an annual percentage rate, a periodic rate, an average daily balance or other stated method, transaction categories, grace-period rules, and the timing of payments and credits.

Financial Learning Cafe explains the subject. Your current agreement, official sources, facts, jurisdiction, and appropriately qualified professionals control the decision.
