Because the rupee is a managed float, a bank's or remittance provider's quoted rate differs from the mid-market rate shown here for two reasons — their own margin, and the fact that the rupee itself can move during the day, occasionally with RBI intervention layered on top.

Banks typically apply a wider spread on USD/INR than dedicated remittance operators or online transfer services, since currency exchange isn't a bank's core product — worth comparing before sending a larger amount.

Card networks convert at their own daily rate, and card issuers commonly add a foreign transaction fee on top — often one to three percent — so a card purchase or ATM withdrawal in India rarely lands exactly on the mid-market figure shown here.

For NRI remittances, the total cost has two parts — the transfer fee, and the margin built into the provider's exchange rate versus the mid-market rate — and the two don't always move together, so the cheapest-looking fee isn't always the best overall deal.

The rate shown here is a frequently updated mid-market reference rate — since the rupee is a managed float rather than a fixed peg, treat it as a benchmark for comparison rather than the exact rate any bank or remittance service will apply.
