Credit Cards
Understand how credit cards work, the different types available, rewards maximization strategies, and how to use credit wisely without falling into debt.
Credit Card KnowledgeHow Credit Cards Work
A credit card is a payment instrument issued by a bank or financial institution that allows you to borrow funds up to a pre-approved credit limit. You can spend now and pay later — either in full (interest-free) or over time (with interest). Understanding the mechanics prevents costly mistakes.
You spend
Use the card at any merchant. The bank pays the merchant immediately on your behalf.
Billing cycle ends
Typically 30 days. All transactions are compiled into your monthly statement.
Due date
Pay by the due date — full amount (no interest) or minimum due (interest applies on rest).
Interest accrues
If outstanding balance remains, interest (24–48% p.a.) is charged from transaction date.

Credit Cards & Your CIBIL Score
Credit cards significantly impact your CIBIL score (credit score). Responsible use builds your score, while misuse damages it. Here's what affects your score:
On-time payments are the single biggest factor. Even one missed payment can drop your score by 50–100 points.
Keep usage below 30% of your limit. High utilization signals credit stress.
Older accounts help. Don't close your first credit card — it boosts average credit age.
Having both secured (home loan) and unsecured (credit card) credit is ideal.
Multiple credit applications in a short period create hard enquiries and lower your score.
