List of countries with highest military expenditures

This is a list of countries with the highest military expenditure in a given year. Military expenditure figures are presented in United States dollars based on either constant or current exchange rates.

Highest military expenditure, total
The first list is based on the Stockholm International Peace Research Institute (SIPRI) fact sheet, which includes a list of the world's top 40 military spenders as of 2023, based on current market exchange rates.

The second list is based on the 2024 edition of The Military Balance, published by the International Institute for Strategic Studies (IISS) using average market exchange rates.

Some sources say that Russian and Chinese military spending are actually far higher than the chart due to captive markets and purchasing price parity in those countries.

Highest military expenditure, share of GDP
The following lists are lists of countries by military spending as a share of GDP - more specifically, a list of the 15 countries with the highest share in recent years - the amount a country has spent on its military as a share of its GDP.

The first list uses SIPRI as a source. The second list gets its data from the International Institute for Strategic Studies.
