The United States led the ranking of the countries with the highest military spending in 2024, with 997 billion U.S. dollars dedicated to the military. That constituted almost 40 percent of the total military spending worldwide that year, which amounted to 2.7 trillion U.S. dollars. This amounted to 3.4 percent of the U.S.'s gross domestic product (GDP), placing the country lower in the ranking of military expenditure as a percentage of GDP, compared to Ukraine, Israel, Algeria, Saudi Arabia, and Russia. China was the second largest military spender, with an estimated 314 billion U.S. dollars spent, with Russia following in third. Defense budgetAccording to the U.S. Congressional Budget Office, the outlays for defense will rise to 1.1 trillion U.S. dollars by 2033. The largest parts of the budget are dedicated to the Departments of the Navy and the Air Force. The budget for the U.S. Air Force for 2024 was nearly 260 billion U.S. dollars.Global military spendingThe value of military spending globally has grown steadily in the past years and reached 2.7 trillion U.S. dollars in 2024. Reasons for this are the outbreak of the Russia-Ukraine war in 2022, the war in Gaza, as well as increasing tensions in the South China Sea. North America is by far the leading region worldwide in terms of expenditure on the military.

In 2023, the military spending worldwide amounted to 2.44 trillion U.S. dollars, which was the highest during the period under consideration. Comparatively, global military spending was at 1.1 trillion U.S. dollars in 2001, and at 1.7 trillion U.S. dollars in 2010, past the peak of the wars in Iraq and Afghanistan. The Russia-Ukraine War The Russia-Ukraine War has been a major driver of more recent military spending increases. From 2021 to 2022, the ratio of Ukraine’s military spending to their GDP increased substantially from 3.8 percent to 33.5 percent. By comparison, this ratio increased in Russia from 3.6 percent in 2021 to only 4 percent in 2022. As a result, large amounts of bilateral aid have gone towards Ukraine. While EU institutions have contributed the most in total, the United States has contributed the most military aid towards Ukraine. Spending by nation Globally, the United States had the largest amount of military spending by large in 2023. The United States spent nearly 916 billion U.S. dollars in 2023 towards defense, compared to 296 billion U.S. dollars and 109 billion U.S. dollars spent by China and Russia respectively. As a percentage of GDP, Ukraine spent the most globally, contributing nearly 37 percent of their GDP to defense, followed by Algeria at 8.2 percent and Saudi Arabia at 7.1 percent.

Military expenditures data from SIPRI are derived from the NATO definition, which includes all current and capital expenditures on the armed forces, including peacekeeping forces; defense ministries and other government agencies engaged in defense projects; paramilitary forces, if these are judged to be trained and equipped for military operations; and military space activities. Such expenditures include military and civil personnel, including retirement pensions of military personnel and social services for personnel; operation and maintenance; procurement; military research and development; and military aid (in the military expenditures of the donor country). Excluded are civil defense and current expenditures for previous military activities, such as for veterans' benefits, demobilization, conversion, and destruction of weapons. This definition cannot be applied for all countries, however, since that would require much more detailed information than is available about what is included in military budgets and off-budget military expenditure items.

As a share of gross domestic product (GDP), Ukraine spent more on its military than any other country in 2024, reaching 35 percent of the country's GDP. The high figure is due to the country being invaded by Russia in February 2022. Israel, that is fighting Hamas in the Gaza war, and Algeria followed behind.Leading military spending countriesIn gross terms, the countries with the highest military spending are the United States, China, and Russia. However, these are countries with large populations and GDPs, and smaller countries usually cannot compete alone, regardless of how much they invest. For this reason, they form alliances such as the North Atlantic Treaty Organization (NATO). NATO countries aim to pool two percent of their GDP towards their own militaries and to aid each other in case of war. Regional differencesThe past decade has seen an increase in global military spending. This has not been distributed evenly. That period saw large positive changes in military spending from several Asian countries, including a large increase from China. While this does not reflect the number of active conflicts, it reflects growing tensions in global affairs.

In 2024, the military spending worldwide amounted to 2.7 trillion U.S. dollars, which was the highest during the period under consideration. Comparatively, global military spending was at 1.1 trillion U.S. dollars in 2001 and at 1.7 trillion U.S. dollars in 2010, past the peak of the wars in Iraq and Afghanistan.

By comparison, this ratio increased in Russia from 3.6 percent in 2021 to only 4 percent in 2022. As a result, large amounts of bilateral aid have gone towards Ukraine. While EU institutions have contributed the most financial and humanitarian aid, the United States has contributed the most military aid towards Ukraine. Spending by nation Globally, the United States had the largest amount of military spending by large in 2024. The United States spent 997 billion U.S. dollars in 2024 towards defense, compared to 314 billion U.S. dollars and 149 billion U.S. dollars spent by China and Russia, respectively.

In 2023, the United States spent around 916.02 billion U.S. dollars on its military. U.S. military spending has been increasing in current dollar terms since 2016. Spending increased dramatically in 2022 after the Russian invasion of Ukraine. After the first year of the war, the U.S. had contributed more than 40 billion euros worth of military aid to Ukraine. What military spending entails Military spending in the United States is the part of the national outlays of the Department of Defense. While the department has over two trillion dollars in budgetary resources, its outlays - money actually paid out - are significantly lower. This budget is designated for the four branches of the United States military, and is used for everything from salaries, trainings, development of new military technologies, and new aircraft and weaponry. The high cost of U.S. spending The United States is well known for spending more on its military than any other country. In 2023, it was estimated that per capita defense spending amounted to 2,220 U.S. dollars. While this figure is extremely high, many Americans may find it worthwhile, as a majority believe the United States to be the number one military power in the world.

The average for 2022 based on 9 countries was 4.83 percent. The highest value was in Colombia: 9.18 percent and the lowest value was in Argentina: 1.26 percent. The indicator is available from 1988 to 2022. Below is a chart for all countries where data are available.

This data collection, which focuses on military spending and arms transfers, supplies information on 145 developed and developing countries of the world. The first file contains background data for each country, including items such as region, sub-region, alliances (OPEC, NATO, and Warsaw Pact), and OECD and World Bank membership. The second file tabulates annual military expenditures, GNP, central government expenditures, arms imports and exports, and total imports and exports in current and constant dollars for each country from 1973 to 1983. Additional variables detail total population, number of armed forces personnel, number of armed forces personnel per 1000 people, GNP in constant dollars per capita, and military expenditures in constant dollars per capita.

This two-part data collection comprises information for military expenditures and transfer of armaments for 142 countries in the period 1966-1975. Part 1 consists of time series data that provide information for national military expenditures, including the yearly value of weapons exports and imports per capita, per soldier, and as a percentage of the gross national product (GNP), as well as the population per million. The country and the year form one unit, so that each country appears ten times. Part 2 data provide additional information about the current values of the total arms exported by each major supplier and the total arms transferred in the period 1964-1974 by the United States, France, United Kingdom, Canada, Poland, China, West Germany, the Soviet Union, and Czechoslovakia.
