Credit card marketing focuses on rewards. Credit card reality is full of fees most cardholders never notice until they see them on a statement. Here are the main ones.

Foreign currency markup

When you swipe your card abroad or on an international website, the issuer applies a markup — typically 3.5% on top of the Visa/Mastercard conversion rate. That's a real cost on every international transaction. Premium cards (Infinia, Magnus, Amex Platinum) offer 0–2% markup and are genuinely worth it for frequent international travelers. Using a forex card or Niyo for international spends is another path.

Cash advance fee

Never withdraw cash from a credit card. You pay a cash advance fee (2.5–3.5%) plus interest from day one at 3–4% per month. A ₹20,000 cash withdrawal can cost ₹700+ upfront and ₹600–800 per month in interest until you pay it back. If you're using a credit card for cash, something has gone badly wrong financially.

Late payment fee

Missing your minimum due triggers a flat fee of ₹500–1,300 depending on the outstanding amount, plus interest on the full billed amount at 3–4% per month from the transaction date. On a ₹50,000 bill, a single missed payment can cost you ₹2,500+. Always set auto-debit for at least the minimum due.

Over-limit fee

Some cards allow you to exceed your limit, then charge 2.5% of the over-limit amount as a fee. Others decline the transaction. Know what your card does.

Fuel surcharge

Fuel transactions carry a 1% surcharge from the payment network. Most fuel credit cards reimburse this up to a monthly cap. Make sure your fuel spend is below that cap — otherwise the surcharge eats your rewards.

The GST

Every fee above attracts 18% GST. A ₹500 late fee becomes ₹590. A ₹10,000 annual fee becomes ₹11,800. Always factor GST into your cost calculations when evaluating whether a fee-based card is worth it.
