What this calculator estimates

International card transactions are generally converted into INR using the card network's settlement rate. The issuer's published forex markup is then applied to the converted value, with GST added to that fee. Enter the rate from your card's current terms rather than relying on a general market average.

How to compare cards for international spending

  1. Compare the published forex markup and GST-inclusive cost.
  2. Check whether international purchases earn rewards and whether those rewards are capped.
  3. Include the annual fee before switching to a travel-focused card.
  4. At overseas terminals, review the local-currency amount before accepting an INR conversion.

DCC and overseas cash withdrawals

This calculator models a foreign-currency purchase after network conversion. Paying an overseas merchant in INR can invoke dynamic currency conversion, while ATM withdrawals can add withdrawal fees and immediate finance charges. Check those separately in the issuer's current terms.

Frequently asked questions

How is a credit card forex markup calculated?

The card network first converts the foreign transaction into INR at its settlement rate. The issuer then applies its forex markup percentage to that converted INR amount, and applicable GST is generally charged on the markup fee.

Does a 3.5% forex markup cost exactly 3.5%?

The final issuer fee can be higher after GST is applied to the markup. Exchange-rate differences, network conversion, DCC and other charges can also affect the final statement amount.

What is dynamic currency conversion?

Dynamic currency conversion, or DCC, is when an overseas merchant offers to bill the transaction in INR. The merchant or its payment provider sets that conversion and your issuer may apply a separate DCC or cross-border charge.

Does zero forex markup mean an international transaction has no extra cost?

It means the issuer's published forex markup is zero. The card-network exchange rate, DCC, ATM fees, cash-advance interest, merchant charges or other applicable taxes can still affect the final cost.
