How much did the US spend in aid to Afghanistan? 

Since 2001, Afghanistan has received more US foreign aid than any other nation. This aid consists of two categories: military spending and economic assistance. Get a deeper understanding of this aid with metrics from the United States Agency for International Development (USAID) and the State Department.

• Military aid primarily benefits government armed forces and does not include the cost of US combat operations. Military spending was 70% of total foreign aid ($91.4 billion) to Afghanistan since 2001. The US spent $3.7 billion on Afghanistan military aid in 2019, the most of any country that year.
   
• According to USAID, $3.64 billion of military assistance went to the Afghanistan Security Forces Fund. The rest was for defense operations and maintenance, counter-drug activities, and international military education and training.
   
• In 2019, the US spent $1.2 billion on economic assistance to Afghanistan. These programs include international narcotics control and law enforcement, plus famine assistance. Economic aid to Afghanistan peaked in 2010 at $4.8 billion.
