In 2015, the EU's 28 Member States earmarked €200 billion of public expenditure for 'defence'. This is equivalent to 1.4% of GDP. This is much less than the amount spent on social protection (expenditure equivalent to 19.2% of GDP in 2015), health (7.2%) or education (4.9%), but significantly higher than public spending on recreation, culture and religion (1.0%), environmental protection (0.8%) and housing and community amenities (0.6%).
Highest share of expenditure on defence in Greece, lowest in Luxembourg
In 2015, the ratio of government defence expenditure to GDP varied across EU Member States from 0.3% in Luxembourg, 0.4% in Ireland, 0.5% in Hungary and 0.6% in Austria, to 2.7% in Greece, 2.1% in the United Kingdom, 1.9% in Estonia and 1.8% in France.
In absolute terms, the United Kingdom spent by far the most on defence (€55 bn in 2015). This is equivalent to over a quarter (27%) of the total EU public expenditure on defence. It was followed by France (€38 bn, or 19% of the EU total), Germany (€30 bn, or 15%) and Italy (€20 bn, or 10%). Together, these four Member States accounted for 72% of the total defence expenditure in the EU.
