Credit Cards: How They Work, Charges and What to Check
A credit card lets you spend up to a limit and pay later. Used carefully it is convenient; used carelessly it can become expensive. This guide explains the basics.
What is a credit card?
A credit card is a payment card issued by a bank or financial institution that lets you borrow money for purchases up to a set limit. You repay the amount later, either in full or in parts.
How credit cards work
When you use the card, the issuer pays the merchant and adds the amount to your statement. If you pay the full statement amount by the due date, you generally pay no interest on purchases. If you do not, interest is charged.
Key terms to understand
| Term | Meaning |
|---|---|
| Credit limit | Maximum amount you can spend on the card, set by the issuer |
| Billing cycle | Period, usually about 30 days, whose transactions appear on one statement |
| Payment due date | Last date to pay to avoid late fees and interest |
| Total amount due | Full outstanding balance on the statement |
| Minimum amount due | Smallest payment that avoids a late fee, but the rest continues to attract interest |
| Finance charges | Interest charged on unpaid balances, often quoted monthly and annually |
Interest and finance charges
Paying only the minimum amount keeps the account active but leaves the balance to grow with interest. Cash withdrawals on a credit card generally attract charges and interest from the day of withdrawal. Check your card's terms for the exact rates.
Annual fees and other charges
- Joining fee and annual or renewal fee (some cards waive these on reaching a spending target)
- Late payment fee
- Foreign currency mark-up
- Cash advance fee
- Over-limit fee, where applicable
- GST on fees and charges
Rewards and cashback
Many cards offer reward points, cashback or travel benefits. Check how points are earned, when they expire, what categories are excluded and whether the benefit is worth the annual fee for your spending pattern.
Credit utilization and credit score
Credit utilization is the share of your limit that you use. For example, spending Rs 30,000 on a Rs 1,00,000 limit is 30% utilization. Consistently high utilization and late payments can negatively affect a credit score, while timely payments support a healthy credit history.
Factors considered during application
- Income and employment details
- Credit score and existing debts
- Age and residence details
- KYC documents such as identity and address proof, and PAN
Issuers decide independently. Meeting a basic criterion does not guarantee approval.
Things to check before choosing a card
- Total yearly cost, including fees and taxes
- Interest rate on unpaid balances
- Whether rewards match your real spending
- Fee waiver conditions
- Customer service and grievance process of the issuer
- Full terms and conditions on the issuer's official website
Frequently asked questions
Is it good to pay only the minimum amount due?
Generally not. The unpaid balance attracts interest, so paying the full amount is usually cheaper.
Do credit cards affect my credit score?
Yes. Payment behaviour and utilization are reflected in your credit report.
Can I have more than one credit card?
Yes, if issuers approve. Manage due dates carefully.
