The cost of U.S. participation in the North Atlantic Treaty Organization (NATO) has been the focus of much discussion and consternation in recent years, all the more so in light of President Trump’s relatively unconventional perspectives on the alliance.

While indirect political and financial costs and benefits of U.S. participation in NATO over the years are worthy of consideration, that’s a subject for another time. But as a starting point, it’s worth understanding the direct costs of U.S. participation in NATO as we prepare for an incoming administration that seems likely to weigh in on the issue.

When people talk about the costs of NATO, they are often referring in large part to the percentage of Gross Domestic Product (GDP) that each NATO member spends on its military. This metric has been an effective means of gauging the relative investments of NATO countries on their respective militaries, which in turn contribute to the alliances’ collective military capabilities. (As an aside, while military spending as a percentage of GDP is useful in this context, it offers a highly skewed and misleading sense of U.S. military spending patterns when considering the U.S. military spending alone, as we explained in opposition to a proposal to ramp up U.S. military spending to 5 percent of GDP.)

Setting shared goals for military expenditures as a percentage of GDP has helped generate buy-in (literally) to the alliance, and in theory helps ensure that no alliance member feels they are putting in more than they get out of the alliance.

In 2014, NATO members agreed to a goal of spending at least 2 percent of GDP on their militaries by 2024. By 2020, only 11 of NATO’s then-30 member nations had met the 2 percent goal. In 2024 however, 23 of NATO’s now-32 member nations had met the 2 percent goal, including the United States, which spent 3.1 percent of its GDP on the military in 2024. Poland topped the list of NATO member spending in 2024 at over 4 percent of GDP.
