The Formula
Exchange rates are fetched live from the Frankfurter API, which sources data from the European Central Bank. Rates are updated on banking business days. The multiplication is straightforward, but the rate behind it reflects complex global macroeconomic forces including monetary policy, trade balances, inflation differentials, and market sentiment.
Variable Definitions
Exchange Rate
How many units of the target currency equal 1 unit of the source currency. This rate reflects the relative value between two economies and fluctuates continuously during market hours based on supply and demand in the global foreign exchange market.
European Central Bank
The authoritative source for reference exchange rates, updated daily at approximately 16:00 CET on banking business days. The ECB reference rates are calculated using a consolidated dataset of electronic trading platform inputs and are used by financial institutions worldwide as benchmark mid-market rates.
Bid-Ask Spread
The difference between the buy and sell price of a currency pair. Retail currency exchanges make their profit on this spread, which is typically 1-3% for banks, 2-5% for airport exchanges, and as low as 0.1-0.5% for specialized online forex brokers. The rate shown is the mid-market rate with zero spread.

Keep in mind that the rate shown is the interbank mid-market rate — your actual bank or exchange service will apply a markup (spread) on top of this rate.
Common Applications
- Convert between major world currencies using live European Central Bank reference rates for international transactions and travel planning.
- Compare the mid-market exchange rate against what your bank offers to calculate the hidden cost of currency conversion markups.
- Plan large international transfers by understanding the true exchange rate before negotiating with forex brokers or banks.
The mid-market rate (shown) has no markup, but banks and exchanges add a 1-3% spread that makes the actual rate less favorable
Understanding the Concept
Exchange rates fluctuate constantly based on global supply and demand, interest rate differentials, inflation, and geopolitical events. The rate shown is the interbank reference rate — actual rates from banks or exchange services include a markup (spread) of 1–5%. The Frankfurter API provides official ECB reference rates, which are the gold standard for financial applications. Understanding the difference between the mid-market rate (shown here) and the retail rate (what you actually pay) is critical when making international transfers or traveling abroad. A 3% spread on a $10,000 transfer is $300 in hidden costs — often more than any transfer fee. The most cost-effective strategy for large international transfers is typically to use specialized forex brokers who offer near-interbank rates with minimal spreads, rather than traditional banks which embed significant markups.
