Exchange rates are determined by the foreign exchange (forex) market, which operates 24 hours a day. Rates fluctuate based on supply and demand, interest rates, inflation, and geopolitical events. This tool uses daily rates sourced from the European Central Bank (ECB).
This tool fetches daily rates from the ECB, updated every business day. For a large financial transaction, always confirm the exact rate with your bank or broker, as they may apply their own margin or fee on top of the mid-market rate.
The US Dollar (USD) is the world's most traded currency, involved in about 88% of all forex transactions. It is followed by the Euro (EUR), Japanese Yen (JPY), British Pound (GBP), and Australian Dollar (AUD).
The mid-market rate (also called the interbank rate or spot rate) is the midpoint between the buy and sell prices of two currencies on the global market. It is the fairest exchange rate you can get. Banks and money services typically add a markup of 1-5% on top of this rate.
For a rough mental estimate, use the approximate rate. For example, if 1 USD = 4.7 MYR, multiply the USD amount by 4.7. But for accuracy, especially for large sums, always use a currency converter with daily rates.
Exchange rates represent the price of one currency expressed in terms of another. They are determined by the foreign exchange market, the largest financial market in the world with over six trillion dollars traded daily. Central banks such as the European Central Bank publish reference rates every business day based on market activity. These mid-market rates reflect the midpoint between what buyers are willing to pay and what sellers are asking. Factors that influence exchange rates include interest rate differentials between countries, inflation expectations, trade balances, political stability, and overall economic performance. When a country raises its interest rates, its currency tends to strengthen because higher returns attract foreign investment. This currency converter uses ECB-backed daily rates to give you a reliable baseline for conversions.
The rate you see in a currency converter is typically the mid-market rate, which is the fairest rate available. However, banks, airports, and money changers almost always add a markup of one to five percent on top of this rate. To get the best deal when exchanging money, avoid airport and hotel currency counters, which tend to charge the highest margins. Instead, compare rates from your bank, online transfer services, and local exchange bureaus before committing. Services like Wise and Revolut often offer rates very close to the mid-market rate with transparent fees. Timing can also matter for large transactions, as rates fluctuate throughout the day and week. If you are not in a rush, monitor the rate for a few days using this currency converter and exchange when the rate moves in your favour. For recurring international payments, consider setting up rate alerts so you never miss a good opportunity.
