Budget for 2010
For the 2010 fiscal year, the president's base budget of the Department of Defense rose to $533.8 billion. Adding spending on "overseas contingency operations" brings the sum to $663.8 billion.
When the budget was signed into law on October 28, 2009, the final size of the Department of Defense's budget was $680 billion, $16 billion more than President Obama had requested. An additional $37 billion supplemental bill to support the wars in Iraq and Afghanistan was expected to pass in the spring of 2010, but has been delayed by the House of Representatives after passing the Senate. Defense-related expenditures outside of the Department of Defense constitute between $216 billion and $361 billion in additional spending, bringing the total for defense spending to between $880 billion and $1.03 trillion in fiscal year 2010.
 Emergency and supplemental spending
The recent invasions of Iraq and Afghanistan were largely funded through supplementary spending bills outside the Federal Budget, so they are not included in the military budget figures listed below. In addition, the Pentagon has access to black budget military spending for special programs which is not listed as Federal spending and is not included in published military spending figures. Starting in the fiscal year 2010 budget however, the wars in Iraq and Afghanistan are categorized as "Overseas Contingency Operations" and included in the budget.
By the end of 2008, the U.S. had spent approximately $900 billion in direct costs on the Iraq and Afghanistan Wars. Indirect costs such as interest on the additional debt and incremental costs of caring for the more than 33,000 wounded borne by the Veterans Administration are additional. Some experts estimate these indirect costs will eventually exceed the direct costs.
