Frequently Asked Questions
Formula: ((New Rate - Old Rate) / Old Rate) × 100. Example: EUR/USD goes from 1.20 to 1.25: ((1.25 - 1.20) / 1.20) × 100 = 4.17% increase. Positive = strengthening, negative = weakening.
Conversion fees typically range from 1-3% for credit cards, 0.5-1% for currency exchange services, and 0.1-0.5% for online platforms. For $1,000 with 2% fee: fee = $1,000 × 0.02 = $20.
Multiply the amount by (1 + fee percentage). For $1,000 with 2.5% fee: $1,000 × 1.025 = $1,025 total cost. The actual fee is $25.
Use services with low percentage fees (0.1-0.5% vs 2-3%), convert larger amounts less frequently to spread fixed fees, use no-foreign-transaction-fee credit cards, or try peer-to-peer currency platforms.
