What Is Credit Card?

What Is Credit Card?: A credit card is a financial tool issued by a bank or financial institution that allows you to borrow money to make purchases, pay bills, or withdraw cash — up to a pre-approved credit limit. In simple terms, it’s like buy now, pay later — you can use the card for expenses today and pay the amount later, usually at the end of the billing cycle.

What Is Credit Card: Credit cards have become an essential part of modern financial life. From online shopping to travel bookings, bill payments, and emergency expenses, a credit card makes your financial life more flexible and convenient.

How Does a Credit Card Work?

When you use a credit card to buy something, you are not spending your own money immediately. Instead, the card issuer pays the merchant on your behalf. You then repay the issuer later — either in full or in part.

Let’s understand this step-by-step:

Purchase: You swipe or use your credit card online to make a purchase.
Billing: The bank adds the transaction amount to your monthly statement.
Grace Period: You get 20–50 days (depending on the bank) to repay the amount without interest.
Repayment: You can either pay the full bill or the minimum amount due (usually 5% of total).
Interest: If you don’t pay in full, the remaining balance attracts interest (ranging from 30%–45% per annum).

Example:
If your credit limit is ₹50,000 and you spend ₹10,000 this month, your remaining limit is ₹40,000. When you repay ₹10,000, your limit resets to ₹50,000 again.

What Is a Credit Card Statement?

Every month, your card issuer sends a credit card statement — a summary of your spending, payments, and total amount due.

It includes:

Total outstanding balance
Minimum amount due
Payment due date
Transaction history
Rewards earned

📅 Example:

Statement Date: 5th November
Due Date: 25th November
If you pay in full before 25th Nov, you pay zero interest.
