Rule 1: Pay Your Bill in Full and On Time
This is the golden rule. Paying your credit card bill on time is the single most important factor for building a healthy credit score. Missing a payment, even by a day, can result in hefty late fees and a negative mark on your credit report that lasts
for years. Many people are tempted to pay only the 'minimum amount due'. Avoid this habit. When you only pay the minimum, the remaining balance accrues interest at a very high rate, sometimes between 30% and 48% annually. This is how people fall into a debt trap. Set up auto-pay for the full statement balance from your bank account to ensure you never miss a due date.
Rule 2: Keep Your Usage Below 30%
Your credit limit is not a spending target. Lenders look at something called the Credit Utilisation Ratio (CUR), which is the percentage of your total credit limit that you've used. For example, if your card limit is ₹1,00,000 and your outstanding balance is ₹30,000, your CUR is 30%. Financial experts recommend keeping this ratio below 30% to show lenders you are a responsible borrower, not heavily dependent on credit. A lower ratio is even better for your score. High utilisation signals financial stress and can negatively impact your credit score, making it harder to get loans in the future.
Rule 3: Guard Your Card Details Like a State Secret
Treat your physical card and its details with extreme care. Never share your card number, expiry date, CVV (the three-digit number on the back), or any One-Time Passwords (OTPs) with anyone. Banks or their representatives will never ask for these details. Be wary of phishing scams that come via email, SMS, or phone calls, trying to trick you into revealing your information. For online transactions, always ensure the website URL starts with 'https://' to confirm it's a secure connection. When shopping in a physical store, make sure the card is swiped in your presence.
Rule 4: Understand the Fees and Charges
Credit cards come with various charges that can add up if you're not careful. These include joining fees, annual fees, late payment fees, and over-limit fees if you spend beyond your sanctioned limit. One of the most expensive mistakes is withdrawing cash from an ATM using your credit card. This 'cash advance' attracts a high fee and, unlike regular purchases, starts accruing interest from the very first day, with no interest-free period. Also, be aware that an 18% GST is applicable on all fees and interest charges.
Rule 5: Review Your Monthly Statement
Your credit card statement is your monthly report card. Make it a habit to check it thoroughly every single month. Look for any transactions you don't recognise. Even a small unfamiliar charge could be a sign of fraud. Reporting unauthorised transactions quickly is crucial; RBI guidelines protect you from liability if you report fraud promptly. Reviewing your statement also helps you track your spending, understand where your money is going, and ensure all your payments have been correctly credited. It’s a simple monthly check-up for your financial health.
Rule 6: Be Cautious About Unsolicited Offers
Once you have a credit card, you may receive offers to upgrade your card or increase your credit limit. According to RBI rules, issuers cannot upgrade your card or change your limit without your explicit consent. Be wary of unsolicited calls promising no-cost EMIs or other deals that sound too good to be true. Always read the fine print. RBI has mandated that lenders must be transparent about the principal and interest components of any EMI conversion. Your first card is for building a history, not for accumulating debt on tempting offers.
