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 participants of the multinational force in Iraq.
As of August 2008, around $550 billion has been spent based on estimates of current expenditure rates, which range from the Congressional Research Service (CRS) estimate of $2 billion per week to $12 billion a month, an estimate by economist Joseph Stiglitz.
Those figures are significantly more 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.". Vice President Cheney didn't comment specifically on the estimate quoted by Russert, noting:
It’s important, though, to recognize that we’ve got a different set of circumstances than we’ve had in Afghanistan. In Afghanistan you’ve got a nation without significant resources. In Iraq you’ve got a nation that’s got the second-largest oil reserves in the world, second only to Saudi Arabia. It will generate billions of dollars a year in cash flow if they get back to their production of roughly three million barrels of oil a day, in the relatively near future. And that flow of resources, obviously, belongs to the Iraqi people, needs to be put to use by the Iraqi people for the Iraqi people and that will be one of our major objectives.
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 dollars 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.
Stiglitz, former chief economist of the World Bank and winner of the Nobel Prize in Economics, has stated the total costs of the Iraq War on the US economy will be three trillion dollars in a moderate scenario, 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. They are conceptually simple, even if occasionally technically complicated. A $3 trillion figure for the total cost strikes us as judicious, and probably errs on the low side. 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."
The CRS estimated in September 2006 that total expenditures had topped half a trillion dollars. Additionally, the extended combat and equipment loss have placed a severe financial strain on the U.S Army, causing the elimination of non-essential expenses such as travel and civilian hiring.
As the total passed US$450 billion, the cost for the Iraq war reached approximately $1500 per person in the United States. If the Iraq war were to wind up costing 1.9 trillion dollars, the cost would be over 4.2 times higher ($6,300 per United States citizen.) This would put the expense at $25,000 for an average family of four, or $32,000 per family if Afghanistan is included.
As a comparison, with this money he estimates that one could have built 8 million houses, paid 15 million teachers, paid for the child care of 530 million kids, paid for the scholarship of 43 million students, offered social safety net during 50 year to Americans. Stigltz also said that United States help for Africa is only $5 billion, soon to be superseded by China. $5 billions correspond to only the spending of 10 days for the war by the United States.
