7 Credit Card Mistakes Indians Keep Making in 2026

By Nitish Bharadwaj · Published Jun 29, 2026 · 5 min

Credit cards reward disciplined users and punish careless ones — often by thousands of rupees per year. Seven habits account for most of the losses: paying only the minimum due, withdrawing cash, missing the billing cycle, applying for too many cards at once, closing old cards unnecessarily, using the wrong card for each spend category, and ignoring reward point expiry. This guide breaks down exactly how each mistake costs you and the precise change to make right now.

A credit card is simultaneously the cheapest short-term credit available in India — 45 days interest-free — and one of the most expensive ways to borrow money at 36–45% annualised if you use it wrong. Which side you land on depends almost entirely on seven habits. Each mistake on this list has a specific mechanism and a specific fix.

Mistake 1: Paying Only the Minimum Due

Per RBI guidelines, the minimum amount due (MAD) is the higher of: (a) 100% of all interest charges, fees, and EMIs billed in the statement, or (b) 5% of the total outstanding balance (minimum ₹200). In practice, for a revolving balance the interest component almost always exceeds 5% of outstanding — so the MAD is driven by interest, not by the 5% floor. Paying it gives you zero late payment fees and keeps your account in good standing — but it does not stop interest from accruing on the remaining balance. Credit cards charge 2.5–3.75% per month (30–45% annualised) on the carried balance from the statement date, not the payment date. A ₹30,000 balance carried for 12 months at 3% per month generates over ₹10,000 in interest alone. Pay the full outstanding every month. Nothing else fixes this — see our deep dive on the minimum amount due trap for the exact RBI formula behind that number and why it never shows up as a payment-history hit.

Mistake 2: Using Your Credit Card for Cash Withdrawals

A credit card cash advance at an ATM charges two things simultaneously: a one-time cash advance fee of 2.5–3% of the amount withdrawn, and daily interest from the day of withdrawal at the card's full monthly rate — with no grace period at all. Withdrawing ₹10,000 costs ₹250–300 upfront, plus approximately ₹300 per month in interest until you repay the full amount. For urgent cash needs, a personal loan or UPI credit line is almost always cheaper.

Mistake 3: Missing the Grace Period and Billing Cycle

Every credit card has a billing cycle (typically 25–30 days) followed by a payment due date 15–25 days after the cycle ends. If you pay the full outstanding by the due date, you pay zero interest on purchases made during that cycle — this is the grace period. Many cardholders miss that the grace period only applies when you pay the full outstanding. If you carried a balance last month, interest runs on new purchases from the day they are posted, not from the statement date. Understanding your billing cycle also allows you to time large purchases: spending just after your statement date gives you up to 50 days of free credit.

Mistake 4: Applying for Multiple Cards in Quick Succession

Each credit card application triggers a hard enquiry on your CIBIL report. A single enquiry typically reduces your score by 5–10 points and remains visible for 24 months. Four applications in one month mean four simultaneous hard enquiries — a signal that lenders interpret as financial stress or desperation. Space card applications at least six months apart. Avoid applying for any credit card in the three to six months before a home loan or car loan application.

Mistake 5: Closing Old Credit Cards

Closing an old credit card shrinks two things at once: your total available credit limit (which raises your credit utilisation ratio) and your average credit age (one of the five CIBIL score factors). A card you have held for seven years that you close today is removed from your average account-age calculation and loses its credit limit from your denominator. The only valid exceptions are cards with annual fees you are not recovering in value. A zero-fee old card is almost always worth keeping open with a small recurring auto-charge that you repay in full.

Mistake 6: Using the Same Card for Every Purchase

No single card maximises rewards across all spending categories. The SBI Cashback card earns 5% on online spends but only 1% offline. HDFC Millennia earns 5% on Amazon, Flipkart, and Myntra but 1% elsewhere. Fuel credit cards waive surcharges at petrol stations that cashback cards do not. Using one card for everything means earning the floor rate on most of your spend. A two-card stack — one for online, one for offline or fuel — typically doubles your effective reward rate without extra annual fees.

Mistake 7: Not Redeeming Reward Points Before They Expire

Reward points are not permanent. Most major bank reward programs expire points after 24–36 months, and some expire points on the card's anniversary date regardless of when they were earned. HDFC reward points expire on the card anniversary. Axis Edge points carry a rolling 2-year validity. Whether it's worth paying a card's annual fee depends partly on whether you will actually redeem the reward points before they expire — accumulated but expired points are worth exactly zero. Before applying for a new card, understand how annual fee waivers work — spend thresholds and exclusion categories changed significantly in 2026 for several major banks.

One more mistake worth adding to this list: not knowing what's already bundled with the card you're paying an annual fee for. Many mid-tier and premium cards carry free purchase protection, air accident cover, and lost-card liability insurance that most cardholders never claim simply because they never knew it existed.
