Informational planning tool only — not investment advice or a trading recommendation. Reference FX may differ from executable bank/card/payment-provider rates that include spreads and fees. This tool does not recommend hedging products.
Method & data
Optional ECB euro foreign exchange reference rates are normalized to 1 foreign = X home via EUR cross rates. Manual or contract rates override references. Fee/spread is an explicit percentage adjustment to the rate.
FAQ
Is the ECB rate my bank rate?
No. ECB publishes reference rates for information. Banks and platforms apply their own spreads.
What if ECB data is unavailable?
The calculator stays usable with a manual or contract FX rate.
Does a 5% FX move cut profit by 5%?
Not necessarily. Profit impact depends on exposure size, other home costs/revenue, and margin structure.
