The mid-market rate
The mid-market (or reference) rate sits halfway between the price at which currencies are bought and sold in wholesale markets. It is the fairest benchmark for comparing offers, because it contains no profit margin. The currency converter on this site uses daily European Central Bank reference rates, so its figures show what a conversion would be worth before any fees.
How the conversion works
Each currency can be quoted against a common base such as the US dollar. On the reference date used in this guide, 1 USD = 96.73 INR, so 100 USD = 9,673.00 INR. For two currencies that are not the base, divide one rate by the other: with 1 USD = 0.89238 EUR, 1 EUR = 96.73 ÷ 0.89238 = 108.40 INR (a cross rate), so 100 EUR = 10,839.55 INR. Pegged currencies are even simpler: the UAE dirham is fixed at 3.6725 per US dollar, so 1,000 AED = 272.29 USD.
How spreads and fees add up
Providers earn money in two ways: a fixed fee, and a spread (a margin added to the rate). Suppose the mid-market rate is 96.73 but a bank offers 94.8. Sending 100 USD returns 9,480.00 INR instead of 9,673.00, a hidden cost of 2.0% before any fixed fee. On larger amounts the difference becomes significant, so always compare the final amount received.
How to compare offers fairly
- Note the mid-market rate from a reference source for the same day.
- For each provider, find the exact amount the recipient will get after all fees.
- Compute the effective rate: amount received ÷ amount sent.
- Compare the effective rate with the mid-market rate to see the true percentage cost.
Card payments and the local-currency trap
When paying by card abroad, a terminal or website may offer to charge you in your home currency. This is called dynamic currency conversion, and the rate it uses usually includes a generous margin. Choosing the local currency and letting your card network convert is often cheaper, though your card issuer may add its own foreign-transaction fee, so check your card terms.
Timing and weekends
Reference rates are published once per working day, and markets move between publications. At weekends and on holidays, converters reuse the last published rates, so a result can differ from the price you are quoted later. For large transfers, ask your provider to lock a rate.

Frequently asked questions
What is the mid-market exchange rate?
The midpoint between the buy and sell prices for a currency pair in wholesale markets. It contains no provider margin.
Why is my bank rate worse than the one I see online?
Banks and transfer services add a spread and often a fee on top of the mid-market rate.
Should I pay in local currency or my home currency abroad?
Usually the local currency. Offers to charge you in your home currency often use a poor exchange rate.
