Brown University Report Estimates U.S. War Costs Since 2001 at $4.79 Trillion
What happened
A report from Brown University’s Watson Institute estimated the total U.S. budgetary cost of war since 2001 at $4.79 trillion, the highest estimate released to date. The calculation includes interest on borrowing, future veterans’ needs, and homeland security costs. The report notes that the wars in Iraq, Afghanistan, Pakistan, and Syria alone cost $1.7 trillion between 2001 and August 2016.

Why it matters
The high cost estimate reflects the massive financial commitment of U.S. overseas operations, which includes costs for the Department of Defense base budget, veterans’ spending, and interest incurred on borrowing. The methodology used in the report mirrors that of Linda Bilmes’ 2008 book, The Three Trillion Dollar War.
