About the Reference Rates

This tool uses static, illustrative exchange rates aligned with approximate Federal Reserve H.10 reference levels (July 2026). They are not live and do not include bank spreads, fees, or intraday moves. For travel, trading, or invoicing, check a current quote from your bank or payment provider.

Conversion Method

Each currency is stored relative to USD. The cross-rate from one currency to another is computed as:

Converted = Amount × (Rate_to ÷ Rate_from)

FAQ

Why don't the rates match my bank? Retail quotes add margins and update continuously. This calculator is for quick estimates and learning, not execution pricing.

Can I enter my own rate? Yes. Use the optional custom rate field to model a quote you received (one unit of the from currency equals X units of the to currency).
