How to Calculate GST on USD to INR Conversions

GST on foreign currency conversion in India generally applies at 18% to the service fee charged by your bank or provider, not to the entire amount you convert. This guide shows you exactly how to estimate GST and the final INR you'll receive.

Key GST rules for forex conversion

• GST is calculated on the provider's conversion fee/commission, not on the full transfer value.
• Exchange rates used by banks/apps include a markup over the mid-market rate.
• Your invoice typically lists base fee + GST (18%) = total fee.

Worked example: USD 100 → INR

Assume a provider fee of ₹250. GST = 18% × ₹250 = ₹45. Total fees = ₹295. If the provider rate is ₹83.20/USD, you receive roughly 100 × 83.20 − 295 = ₹8,025. Add your own numbers from the provider for accuracy.

Tips to reduce costs

• Compare providers (Wise, Remitly, banks) for better rates and lower fees.
• Send larger but less frequent amounts to reduce fixed fees impact.
• Check the "received amount" estimate before confirming.
