Credit Cards

Credit Cards

A credit card is a payment card issued by a financial institution allowing its holder to borrow funds with which to pay for goods and services with merchants who accept the card. Unlike a debit card, which draws money directly from a checking account, a credit card provides a line of credit. This means you're borrowing money that you agree to pay back later, typically with interest if not paid in full by the due date. Understanding credit cards is a foundational element of Personal finance and responsible Debt management.

How Credit Cards Work

The basic process unfolds as follows:

1. Transaction: You use your credit card to make a purchase. 2. Authorization: The merchant requests authorization from your card issuer (the bank or financial institution). 3. Credit Limit Check: The issuer verifies you have available credit (within your Credit score-determined limit). 4. Purchase Approval: If approved, the transaction goes through. 5. Billing Cycle: Transactions are accumulated over a billing cycle, usually around a month. 6. Statement: You receive a statement detailing your purchases, payments, fees, and the total amount due. 7. Payment: You can pay the full balance, a minimum payment, or any amount in between.

Failing to pay the full balance results in Interest charges applied to the remaining amount. These charges, expressed as an Annual Percentage Rate (APR), can significantly increase the cost of your purchases.

Key Terms

Understanding these terms is crucial:

• Credit Limit: The maximum amount you can charge on the card.
• APR (Annual Percentage Rate): The annual cost of borrowing money on the card, including interest and fees. Different APRs may apply to purchases, Cash advances, and Balance transfers.
• Minimum Payment: The smallest amount you must pay each month to avoid late fees and damage to your Credit history. Paying only the minimum can lead to significant interest accrual.
• Grace Period: The time between the end of your billing cycle and the payment due date. If you pay your balance in full during the grace period, you avoid interest charges.
• Credit Utilization Ratio: The amount of credit you're using divided by your total credit limit. Keeping this ratio low (ideally below 30%) positively impacts your Credit rating.
• Cash Advance: Borrowing cash directly from your credit card. These typically have high APRs and fees.
• Balance Transfer: Moving debt from one credit card to another, often to take advantage of a lower APR.
