With Russia's invasion of Ukraine, the role and capabilities of NATO, including defense spending, are in the spotlight (Economist, US News & World Report, NATO).

In case of any ambiguity between the PDF and the spreadsheet downloads, figures per "Download the tables in Excel format" will be used. According to the June 2024 report, which included estimates for 2024 spending, 23 countries spent 2.0% or more of their real GDP on defense, up from 10 in 2023 (NATO - Defence Expenditure of NATO Countries (2014-2024), see Download options at bottom of page and reference Table 3). Please note that Iceland, while a member of NATO, has no armed forces and therefore no defense expenditures.
