Here are average Western European real estate commissions.
UK: 1.0%
Denmark: 1.25%
Ireland: 1.75%
Greece: 2.0%
Lithuania: 2.25%
Spain: 2.75%
Belgium: 3.0%
Estonia: 3.0%
Luxembourg: 3.0%
Netherlands: 3.0%
Poland: 3.0%
Austria: 3.5%
Finland: 3.75%
Portugal: 4.0%
Sweden: 4.0%
Germany: 4.5%
Italy: 4.5% (split between 2 parties)
France: 5.0%
This is notably lower than the US standard of 6%. Keep in mind this represents the total commission paid, except Italy, (not split between two agents), and France’s authority has actually recommended lowering their average to match the European average.
