What is the currency conversion and rounding rule regarding the euro as an official currency in Bulgaria?

Bulgaria’s conversion from levs to euros follows strict rules using a fixed exchange rate expressed with five decimal places, without rounding or truncation. Converted amounts are then rounded to two decimal places based on standard rounding rules, unless specific legislation requires otherwise.

The process of converting Bulgarian levs to euros leads to strict guidelines to ensure accuracy and consistency as the country transitions to the euro.

Regarding calculation and conversion rules, the conversion is performed by dividing the amount in levs by the official exchange rate. This rate is expressed in full numerical form, including six digits with all five decimal places, and is neither rounded nor truncated.

The resulting amount after conversion is rounded to the second decimal place based on the third decimal place, following these rules:

• If the third decimal place is less than five, the second decimal place remains unchanged.

• If the third decimal place is five or greater, the second decimal place is increased by one unit.

Specific rounding rules may apply in cases where Bulgarian or European Union laws stipulate rounding to a different decimal point.
