Why exchange rate matters to a first-time founder
Exchange-rate movements change the home-currency value of foreign sales, supplier bills and investments. A profitable contract can lose its margin before payment arrives. Founders trading internationally should decide who bears that risk and avoid assuming the rate shown in a news report is the rate their bank will offer.
Examples of exchange rate
A UK company invoices a customer €50,000 when £1 buys €1.20, implying about £41,667. By payment, £1 buys €1.25, so the euros convert to £40,000 before fees. The company receives about £1,667 less than expected because sterling strengthened against the euro.
Common misunderstanding
An exchange rate is not usually the final customer price for converting money. Providers add a spread, which is the difference between their buy and sell rates, and may charge fees. Also state the direction clearly: EUR/GBP and GBP/EUR are reciprocal quotes, not interchangeable figures.
When to use it
Use a realistic rate whenever pricing, forecasting or signing a contract in another currency. For material exposure, set a tolerance, consider matching receipts with payments and discuss hedging with a regulated provider. Small or infrequent amounts may not justify complex protection, but conversion fees still belong in the budget.
