Financial cost of the Iraq War

The following is a partial accounting of financial costs of the 2003 Iraq War by the United States and the United Kingdom, the two largest non-Iraqi participants of the multinational force in Iraq.

The costs of the 2003-2010 Iraq War are often contested, as academics and critics have unearthed many hidden costs not represented in official estimates. The most recent major report on these costs come from Brown University in the form of the Costs of War, which totaled just over $1.1 trillion. The Department of Defense's direct spending on Iraq totaled at least $757.8 billion, but also highlighting the complementary costs at home, such as interest paid on the funds borrowed to finance the wars.

Those figures are dramatically higher than typical estimates published just prior to the start of the Iraq War, many of which were based on a shorter term of involvement. For example, in a March 16, 2003 Meet the Press interview of Vice President Dick Cheney, held less than a week before the Iraq War began, host Tim Russert reported that "every analysis said this war itself would cost about $80 billion, recovery of Baghdad, perhaps of Iraq, about $10 billion per year. We should expect as American citizens that this would cost at least $100 billion for a two-year involvement."

According to a Congressional Budget Office (CBO) report published in October 2007, the U.S. wars in Iraq and Afghanistan could cost taxpayers a total of $2.4 trillion by 2017 when counting the huge interest costs because combat is being financed with borrowed money. The CBO estimated that of the $2.4 trillion long-term price tag for the war, about $1.9 trillion of that would be spent on Iraq, or $6,300 per U.S. citizen. The most recent CBO report, which was conducted after the end of combat operations and hence did not have to estimate future costs, was released in December 2014 and placed the cost at $0.815 trillion.

Joseph Stiglitz, former chief economist of the World Bank and winner of the Nobel Prize in Economics, and Linda Bilmes of Harvard University, have stated the total costs of the Iraq War on the US economy will be three trillion dollars in a moderate scenario, described in their book The Three Trillion Dollar War and possibly more in the most recent published study, published in March 2008. Stiglitz has stated: "The figure we arrive at is more than $3 trillion. Our calculations are based on conservative assumptions...Needless to say, this number represents the cost only to the United States. It does not reflect the enormous cost to the rest of the world, or to Iraq."
