The US government has spent over $2.26 trillion on its failed war in Afghanistan, according to the latest numbers from Brown University's Costs of War Project. The report also estimates that the war has directly killed 241,000 people in Afghanistan and Pakistan.

The $2.26 trillion in spending was broken down into five categories. The single greatest expense was $933 billion, which was covered by the Defense Department's Overseas Contingency Operations Budget. The second-highest cost is the estimated interest accrued by borrowing money for the war, which accounts for $530 billion.

The Pentagon's base budget saw increases over the years for the war in Afghanistan that accounts for the third-highest expense at $443 billion. Care for veterans of the war comes in fourth at $296 billion, a number that will continue to rise for decades to come. The State Department's budget for Afghanistan comes in fifth at $59 billion.
