Formula

  • Converted = amount × rate
  • Received = amount × rate × (1 − margin) − fee

Banks and cards rarely give the mid-market rate you see online — they add a spread of 1–3% and often a flat fee. This calculator shows both the ideal conversion and what actually lands in the account, so you can compare providers. For live mid-market rates use the currency converter.
