How this calculation works
Cross ECB reference rates quoted per euro: destination units per source unit = destination-per-EUR ÷ source-per-EUR. Alternatively use your quoted rate. Reduce that rate by the entered provider spread, convert, then deduct the destination-currency fee, floored at zero.
A worked example
At a custom rate of 18 destination rand per US dollar, USD100 converts to R1 800 before spread and fees.
Assumptions & limitations
- Stored reference rates are dated 5 November 2026, not a live trading quote. Check your provider’s executable rate and current fees before a transaction. Same-currency conversion still applies any fees or spread you explicitly enter.
