The EU economy largely depends on a few countries, particularly its ‘Big Four’. As of 2025, Germany, France, Italy and Spain together account for 61% of the EU’s GDP.

However, countries’ shares of the EU economy change over time. The share held by the ‘Big Four’ has been declining in recent decades. It fell from 67.9% in 2005 to 65.3% in 2015 and 61% in 2025, according to Eurostat.

So, which countries have the highest and lowest GDP shares? And how have these shares changed across the EU over time?

Almost a quarter of the EU’s GDP comes from Germany

Germany is by far the largest economy in the EU. In 2025, Germany produced 24.1% of the EU’s GDP. The EU’s total GDP was €18.8 trillion in 2025, of which Germany generated around €4.5 trillion.
