Live vs mid-market rates
This converter uses the mid-market rate — the midpoint between buy and sell prices. Banks and services like PayPal, Wise, or your credit card typically add a 1–4% margin on top. For large transfers, always compare the actual rate you'll receive, not just the mid-market rate shown here.
Currency converter for invoicing
When billing international clients, agree on a currency upfront — ideally USD if you're US-based. Use this tool to give clients an approximate local equivalent. Add "payment in USD" to your invoice terms to avoid exchange rate risk. The Invoice Generator on this site supports 7 major currencies.
Exchange rate volatility
Major currency pairs (EUR/USD, GBP/USD) typically move 0.5–1% per day. Emerging market currencies can move 2–5%+ on economic news. If you're quoting prices in a foreign currency for a project spanning several weeks, consider building a currency buffer or using a forward contract to lock in today's rate.
How exchange rates work
Exchange rates are set by supply and demand in the global forex market — the largest financial market in the world at $7.5 trillion traded daily. Rates shift based on interest rates, inflation, economic growth, political stability, and market sentiment. Central bank decisions (like Fed rate changes) are the single biggest short-term driver.
Understanding Exchange Rates and Currency Conversion
Currency exchange rates represent the price of one currency expressed in terms of another. They fluctuate constantly based on interest rate differentials between countries, inflation rates, trade balances, political stability, and market sentiment. The rate you see quoted (the "spot rate") is the mid-market rate — the midpoint between the buy and sell prices that banks and brokers trade at. The rate you receive as a consumer will always be worse than the spot rate, because providers build their margin into the exchange.
How to Get the Best Exchange Rate
For international travel, the best rates are typically found through banks and credit unions before you travel, or through ATM withdrawals in your destination country using a fee-free debit card (like Charles Schwab or Wise). Airport currency exchanges and hotel front desks offer the worst rates — often 10-15% below the mid-market rate. Credit cards with no foreign transaction fees often provide rates very close to the spot rate.
Fixed vs Floating Exchange Rates
Most major currencies (USD, EUR, GBP, JPY, etc.) are freely floating — their rates are set by market forces. Some currencies are pegged to the US dollar or another major currency at a fixed rate maintained by the government, such as the Hong Kong dollar (pegged at ~7.8 HKD per USD since 1983). Exchange rates for pegged currencies are stable against their anchor currency but can experience sudden revaluations if the peg becomes unsustainable.
