How to Calculate Exchange Rate Manually

Calculating a currency exchange involves more than just multiplying two numbers. To get an accurate figure, you must account for the mid-market rate and the markup applied by the financial institution.

The Basic Formula

Total Received = (Amount × Exchange Rate) × (1 – Fee Percentage)

Understanding the Components

  • Base Amount: The quantity of the initial currency you hold.
  • Exchange Rate: The value of one currency in relation to another (e.g., 1 USD = 0.92 EUR).
  • Spread/Fee: Banks rarely give you the "real" rate seen on Google. They add a percentage (usually 2-4%) to the rate to make a profit.

Step-by-Step Example

Imagine you want to convert 500 USD to EUR. The current market rate is 0.90, but your bank charges a 3% conversion fee.

  1. Multiply by rate: 500 × 0.90 = 450 EUR.
  2. Calculate fee: 450 × 0.03 = 13.50 EUR.
  3. Subtract fee: 450 – 13.50 = 436.50 EUR.

In this scenario, you would actually receive 436.50 EUR after the bank takes its cut.
