In 2023, the US military spent approximately $820.3 billion, or roughly 13.3% of the entire federal budget for that fiscal year. In March 2023, the Department of Defense (DoD) requested $842.0 billion for 2024 — a 2.6% increase.
With the world’s third-largest military, at nearly 1.3 million active-duty troops, the US estimates it spends more than any other nation on its national defense. Between 2014 and 2022, the US spent more than twice as much on defense as did all other NATO members, 30 nations in total.
