Too bad in this otherwise good article the real costs to the people and culture of Iraq are not in the calculations. Nevertheless it gives some good details.
Waging the trillion-dollar war

CAMBRIDGE, Massachusetts The human cost of the more than 2,000 American military personnel killed and 14,500 wounded so far in Iraq and Afghanistan is all too apparent. But the financial toll is still largely hidden from public view and, like the suffering of those who have lost loved ones, will persist long after the fighting is over.
The cost goes well beyond the more than $250 billion already spent on military operations and reconstruction. Basic running costs of the current conflicts are $6 billion a month - a figure that reflects the Pentagon's unprecedented reliance on expensive private contractors.
Other factors keeping costs high include inducements for recruits and for military personnel serving second and third deployments, extra pay for reservists and members of the National Guard, as well as more than $2 billion a year in additional foreign aid to Jordan, Pakistan, Turkey and others to reward their cooperation in Iraq and Afghanistan.
But the biggest long-term costs are disability and health payments for returning troops, which will be incurred even if hostilities were to stop tomorrow. The United States currently pays more than $2 billion in disability claims per year for 159,000 veterans of the 1991 Gulf war, even though that conflict lasted only five weeks, with 148 dead and 467 wounded.
