Short answer: The main credit card charges to know are the annual/joining fee, finance charges (interest of roughly 30%–48% a year if you don’t pay in full), late payment fees, cash advance fees, and forex markup on international spends. On top of every fee, 18% GST applies. The good news: pay your bill in full and on time, and you avoid the two biggest costs entirely.
A credit card is only expensive if you don’t understand its charges. Here’s every one, in plain language.
1. Joining and annual fees
Many cards charge a one-time joining fee and/or a recurring annual (renewal) fee, which can range from zero to several thousand rupees depending on the card.
How to minimise it: Choose a lifetime-free card (no annual fee ever), or a card whose annual fee is waived when you cross a yearly spend threshold. If you naturally spend above that threshold, you effectively pay nothing.
2. Finance charges (interest)
This is the big one. If you don’t pay your Total Amount Due by the due date, the unpaid balance attracts interest — commonly 2.5%–4% per month, which works out to roughly 30%–48% per year — calculated daily and compounding. Carrying a balance also means you lose the interest-free period on new purchases.
How to avoid it: Pay your statement in full, every month. Do this and finance charges are simply zero.
3. Late payment fees
Miss the due date and you’re charged a late fee, typically on a slab basis (often around ₹100 up to ₹1,300+, depending on your outstanding balance). Late payments can also hurt your credit score.
How to avoid it: Set up auto-pay. A useful trick: paying at least the minimum due keeps you “paid” and avoids the late fee — though you’ll still pay interest on the rest, so paying in full is always best.
4. Cash advance fees
Withdrawing cash from an ATM using your credit card is one of the most expensive things you can do with it. You pay a cash advance fee of around 2.5%–3% of the amount (with a minimum), and interest starts from day one — there’s no interest-free period on cash withdrawals.
How to avoid it: Treat credit card cash withdrawals as a last resort. A UPI payment, debit card, or even a personal loan is almost always cheaper.
5. Forex markup (foreign currency fee)
Spend in a foreign currency — abroad, or on international websites and subscriptions — and you’re charged a forex markup, typically 1.5%–3.5% of the transaction, plus 18% GST on that fee. Watch out for subscriptions (some streaming services) that quietly bill in a foreign currency.
How to reduce it: If you travel or spend internationally often, a zero-forex-markup card or a dedicated forex card can save meaningfully. Always choose to pay in the local currency at international merchants (never accept “dynamic currency conversion” to INR). Note that very large international spends in a year may also attract TCS under India’s remittance rules.
6. The one that applies to all of them: 18% GST
Here’s what most people miss: 18% GST is added on top of every credit card fee and charge — annual fees, interest, late fees, cash advance fees, forex markup, the lot. It does not apply to your regular purchases, only to fees and interest. So a ₹1,000 fee actually costs you ₹1,180.
How to reduce it: You can’t change the GST rate, but you can shrink the base it’s applied to — by avoiding fees in the first place. No fee means no GST.
Other charges to be aware of
- Fuel surcharge: usually around 1% at petrol pumps, though many cards waive it up to a monthly cap.
- Over-limit fee: charged if you spend beyond your credit limit (you can usually disable over-limit spending).
- Reward redemption fee: some cards charge a small fee (often around ₹100) to redeem reward points.
- EMI conversion charges: converting a purchase to EMIs often carries a processing fee, and the “flat” rate can be pricier than it looks.
- Card replacement fee: for reissuing a lost or damaged card.
The bottom line: how to pay almost nothing
Most credit card charges are avoidable. Stick to these and your card can cost you virtually nothing while still earning rewards:
- Pay your full statement balance by the due date — eliminates finance charges and late fees (and their GST).
- Choose a lifetime-free card or one whose fee waives on your normal spend.
- Never withdraw cash on your credit card.
- Use a low/zero-forex card for international spends, and pay in local currency.
- Read the schedule of charges before you apply, so nothing surprises you.
Frequently asked questions
Is GST charged on credit card purchases?
No. GST at 18% applies only to fees, interest, and penalties charged by the bank — not to your regular purchases.
What is the most expensive credit card charge?
Carrying a balance (finance charges of ~30%–48% a year) and cash advances are the costliest. Both are easily avoided by paying in full and not withdrawing cash.
Does a lifetime-free card mean zero charges?
No. It means no joining or annual fee, but other charges — like interest on unpaid balances, cash advance fees, or forex markup — can still apply based on how you use it.
How can I avoid my credit card annual fee?
Pick a lifetime-free card, or meet the annual spend threshold at which your bank waives the fee. Some banks also waive it on request before renewal.
Why did interest appear even though I paid the minimum due?
Paying only the minimum avoids the late fee but not interest — finance charges apply to the remaining unpaid balance, and you lose the interest-free period on new purchases.
Know your fees, keep your rewards
Understanding the charges is what separates a card that costs you money from one that pays you. A lifetime-free, app-managed card makes it easy: the Jupiter Edge+ RuPay Credit Card has no annual fee, shows every charge clearly in the app, and lets you pay your full bill in a tap — so you keep the cashback and skip the costs.
Specific fees, interest rates, GST application, and waiver thresholds vary by issuer and card and are subject to change. Always refer to your card’s schedule of charges. This article is general information, not financial advice.
