Business Currency Converter
Convert between currencies for international business transactions.
Formula
Converted Amount = Original Amount × Exchange Rate Inverse Rate = 1 / Exchange Rate
How to Calculate
Currency conversion multiplies the amount in one currency by the exchange rate to get the equivalent in another currency. Exchange rates fluctuate constantly based on market conditions, interest rates, inflation, and geopolitical factors. Always use the current rate for transactions, not historical rates.
Be aware of the difference between the mid-market rate (the "real" exchange rate you see on Google or financial sites) and the rate you actually receive. Banks, payment processors, and currency exchange services add a spread (markup) of 0.5–4% above the mid-market rate. This spread is their profit and represents a hidden fee on every international transaction.
For business accounting, you need to record foreign currency transactions at the exchange rate on the transaction date. When you settle the payment later, any change in the exchange rate creates a foreign exchange gain or loss that must be recognized in your books. For significant international operations, consider hedging strategies to protect against currency fluctuation risk.
Worked Example
A US business invoices a UK client £50,000 when the GBP/USD exchange rate is 1.27.
USD equivalent: £50,000 × 1.27 = $63,500
The business records $63,500 in accounts receivable. When the client pays 30 days later, the rate has moved to 1.25.
Actual USD received: £50,000 × 1.25 = $62,500 Foreign exchange loss: $63,500 − $62,500 = $1,000
If using a bank wire with a 1.5% spread: Effective rate: 1.25 − (1.25 × 1.5%) = 1.23 Actual received: £50,000 × 1.23 = $61,563 Total cost vs. invoice: $63,500 − $61,563 = $1,938
Why It Matters
For businesses operating internationally, currency conversion directly impacts pricing, profitability, and cash flow. Exchange rate fluctuations can turn a profitable deal into a loss. Understanding conversion costs, including hidden spreads, helps you price international work correctly, choose cost-effective payment methods, and manage foreign exchange risk.
