What Cards Charge Abroad
- •Standard credit/debit cards: 3.5% forex markup on every international transaction.
- •18% GST applies on the markup fee — so 3.5% is really about 4.13%.
- •Zero-forex and travel cards charge 0%–2%; the network conversion itself is near mid-market.
- •"Pay in INR" at a foreign terminal (DCC) costs 5%–8% — always choose the local currency.
The Real Problem This Solves
Nobody reads the line "forex markup: 3.5% + GST" when they get a card — they discover it after a trip, spread across twenty transactions, each quietly 4% more expensive than the rate they saw on Google.
On a two-week Europe trip or a semester of US expenses, that's thousands of rupees for nothing. This calculator shows the true INR cost of any foreign spend on your card — and how much a zero-forex card, or simply pressing the right button at the terminal, would save.
How Card Forex Charges Stack Up
Three layers sit between the mid-market rate and your statement: the network's conversion (Visa/Mastercard, usually within ~0.3% of mid-market), your bank's forex markup on the converted amount, and 18% GST on that markup fee.
Example: Nikhil spends $1,000 abroad with the dollar around ₹96. Mid-market value: ₹96,000. His standard card adds 3.5% (₹3,360) plus 18% GST on that fee (₹605) — the statement shows about ₹99,965, an effective 4.13% premium. A zero-forex card would have charged ₹96,000-odd. Same trip, ₹3,965 saved — per thousand dollars.
And if he'd pressed "pay in INR" at the terminal? Dynamic currency conversion rates typically run 5-8% worse than mid-market, before his card's own markup. It's the single most expensive button in travel.
| Card / Choice | Effective Cost Over Mid-Market | On $1,000 (~₹96,000) |
|---|---|---|
| Zero-forex card | ~0% | ~₹0 |
| Travel card (1%) | 1.18% (with GST) | ~₹1,133 |
| Premium card (2%) | 2.36% | ~₹2,266 |
| Standard card (3.5%) | 4.13% | ~₹3,965 |
| "Pay in INR" (DCC) | 5%–8%+ | ₹4,800–₹7,700+ |
Frequently Asked Questions
What is a forex markup fee?
A percentage your bank adds to every transaction made in a foreign currency, on top of the network's conversion rate. Most standard Indian cards charge 3.5%, and 18% GST applies on that fee — making the true cost about 4.13% of the spend.
Should I pay in INR or the local currency abroad?
Always the local currency. Choosing INR triggers dynamic currency conversion (DCC): the merchant's processor sets the exchange rate, typically 5-8% worse than mid-market, and your card's markup may still apply. The terminal makes INR look reassuring — it is the expensive option.
Do zero-forex cards really have no markup?
Genuine zero-forex cards charge 0% markup, and the network conversion is close to mid-market — so your cost is within a fraction of a percent. Check the card's annual fee and whether the 0% applies to both purchases and ATM withdrawals; ATM operators abroad add their own charges either way.
Does TCS apply to international card spending?
Credit card spends abroad are currently outside LRS TCS. Loading a forex card or remitting through your bank does count toward LRS. For large trips the split matters — run planned remittances through our TCS calculator.
