If you own a credit card, you are authorized to charge purchases against a pre-approved line of credit. Credit cards may be issued by banks, retailers, and other credit grantors. Some card issuers charge an annual fee to cover account-servicing costs, others do not.

After making purchases with a credit card,
they become payable after a Grace Period during which no finance charge is imposed.Afterward,the balance due may be paid in full or paid down in monthly installments with interest.This is commonly known as revolving credit.

Some card issuers charge credit card interest from the purchase date whether the cardholder's account has an outstanding balance or not.  Credit card interest rates, interest calculations, annual fees and repayment terms may vary considerably among cards.
