Look up a currency conversion online, then check what your bank or card statement actually charged for the same transaction, and the two numbers rarely match. That gap isn't an error in either source — it comes down to which specific exchange rate each one is quoting.
What a Reference Rate Actually Is
The rate you see on a general currency converter is typically a mid-market (or "interbank") reference rate — the midpoint between the buy and sell prices that banks and financial institutions actually trade currency at with each other, in enormous volumes, with no markup added. It's the closest thing to a neutral, objective "true" exchange rate at a given moment. No individual person or business can usually access that exact rate for their own transaction, though — it's a benchmark, not a retail offer.
Why Your Bank's Rate Is Always Worse
Banks, card networks, and currency exchange services build a profit margin into every conversion, which shows up as a markup on top of the mid-market rate rather than as a separate visible fee. A wide markup means the rate they give you is noticeably worse than the mid-market reference rate; some providers also charge an additional flat foreign transaction fee on top. This is standard across the industry — the mid-market rate is a useful baseline for judging how good or bad a specific deal is, not a rate you should expect to receive yourself.
Why Rates Update Daily, Not Every Second
Actual currency markets trade continuously and rates shift by the second, but most free, publicly available exchange rate data isn't refreshed that often — daily updates are the common standard for reference-rate services, since continuous live-market data feeds are typically a paid product reserved for financial institutions and trading platforms. A daily rate is accurate enough for everyday conversions and budgeting, but it isn't a live trading quote, and shouldn't be treated as one for anything time-sensitive like an actual trade.
Reading a Cross Rate
Currency data is usually published against one base currency — commonly the US dollar — rather than as a direct rate for every possible pair of currencies. Converting between two non-USD currencies, say Euros to British Pounds, typically happens in two steps behind the scenes: Euros to Dollars, then Dollars to Pounds. This two-step conversion is called a cross rate, and it's mathematically identical to a direct rate — it just relies on the base currency as a common intermediate rather than every currency pair being tracked independently.

FAQ
How often are exchange rates updated? Once a day. Rates are pulled from a free, publicly available exchange rate service and cached in your browser for up to 12 hours before checking for a fresh set, so most visits use an already-cached rate rather than making a new request every time.
Are these real-time, live trading rates? No — these are daily reference rates, not second-by-second interbank trading rates. Actual currency markets move continuously throughout the day, so a rate shown here can differ slightly from what you'd see on a live trading platform at that exact moment.
Why is the rate my bank or card gave me different from a reference rate? Banks, card networks, and money transfer services typically add their own markup on top of the market exchange rate, plus sometimes a separate foreign transaction fee. A reference rate is the underlying market rate, not what any specific bank or provider will actually charge you.
What does it mean when a currency pair is quoted "via USD"? Most currency data providers publish rates against a single base currency (commonly USD) rather than every possible pair directly. Converting between two other currencies, like EUR to GBP, is done by first converting EUR to USD and then USD to GBP — a cross rate — which is mathematically equivalent to a direct rate but relies on the base currency as an intermediate step.
