The Stockholm International Peace Research Institute (SIPRI) compiled the ratio of military expenditure to gross domestic product (GDP) for two countries currently at war: Israel and Iran.
Over two decades, Israel's military expenditure-to-GDP ratio has been significantly higher than Iran's.
Israel's ratio has generally been above 5% of GDP, with only 2021 and 2022 showing lower figures of 4.9% and 4.4% respectively. The latest data for 2024 shows a surge to 8.8%, the highest in the last 20 years.
Meanwhile, Iran's proportion has remained in the 2%-3% range of GDP. Its highest figure was 3.3% in 2006—considerably lower than Israel's.
Interestingly, when measured by government budget allocation for military spending, the proportions for both countries are not so far apart. From 2000-2022, both countries' government spending on military was in the 11%-19% range.
However, the latest data for 2023 shows a significant increase in Israel's military spending to 20% of its total government expenditure, while Iran's remained at 12.5%. The increase in Israel's spending is believed to be due to the massive attacks on Palestine during the October 7, 2023 tragedy.
