How currency exchange rates work

The reference (mid) rate is the midpoint of the wholesale market, published daily by the European Central Bank. Exchange offices quote a buy rate below it and a sell rate above it; the difference — the spread — is their compensation. To compare offers, always compare the final amount you receive, not the advertised rate alone, and ask for a written quote for larger amounts. Since 2026 the euro is Bulgaria's currency, so EUR is the base for all our rates.
