The fee that quietly adds 1.5–3.5% to every international transaction — and why it matters more than your reward rate abroad.
Updated 2026-08
Foreign currency markup (also called cross-currency or forex markup) is a fee your card network and issuer add on top of the base exchange rate whenever you spend in a currency other than rupees — whether that's swiping abroad, paying a foreign website, or booking a hotel priced in dollars. It typically ranges from 1.5% to 3.5% of the transaction value, charged silently as part of the converted amount rather than as a separate visible line item.
It applies per transaction, not per trip — so ten small purchases on a holiday each carry the markup independently. On a ₹1 lakh international trip, the difference between a 1% and a 3.5% markup card is roughly ₹2,500, which is often larger than any reward points you'd earn on that same spend.
A common misconception is that forex markup only matters if you're physically abroad. It applies equally to any transaction billed in a foreign currency — international SaaS subscriptions, overseas online shopping, or app store purchases billed in USD — even when you never leave India. If a meaningful share of your regular spend is in foreign currency for this reason, forex markup deserves the same weight as domestic reward rates when choosing a card.
Several travel-focused premium cards advertise reduced or zero forex markup as a core benefit, sometimes alongside lounge access, specifically because their target user travels internationally often enough for the fee to matter. These cards can carry a higher annual fee, but for a frequent traveller the forex savings alone can exceed the fee difference within one or two international trips.
If you travel abroad rarely, a low-forex-markup card is a lower priority — the savings only accumulate with meaningful foreign-currency spend, so a card matched to your domestic spend pattern usually wins for occasional travellers.
Multiply your expected foreign-currency spend for the trip by your card's markup percentage — that's the fee you'll pay regardless of any rewards earned on the same spend. Compare that number against what a lower-markup card in your wallet (or one you're considering) would charge on the same amount, and against any reward points you'd forgo by switching cards for the trip.
For most travellers, the simplest rule holds: for large or frequent international spend, a dedicated low-forex card beats a high-reward domestic card, even if the domestic card's headline reward rate looks better on paper.
