Common mistakes
Treating reference rates as bank quotes
Fix: CalcVo rates are illustrative; confirm with your financial institution.

Fix: Factor in wire fees and card foreign transaction fees separately.
Confusing direct and inverse rates
Fix: Check both rates shown — 1 USD = 0.92 EUR is not the same as 1 EUR = 1.09 USD.
