A live cost tracker estimates U.S. military operations against Iran at $380 million per day during initial strikes, with total spending projected to exceed $8 trillion over 20 years when including post-9/11 conflicts. The model breaks down daily costs across personnel, naval forces, aircraft operations, fuel, munitions, and overhead, tracking both ongoing expenses and discrete one-time costs like aircraft losses.

Each phase of operations carries different price tags: $220 million daily for sustained operations and $155 million daily for air dominance phases. The tracker uses bottom-up methodology drawing from DoD flight-hour rates, GAO sustainment reports, and Navy operating costs. Three aircraft lost to friendly fire alone represent $270 million in replacement costs.

Analysts note the model captures only 60-75% of true costs, excluding long-term veteran healthcare, economic opportunity costs, and energy market disruptions. Historical comparisons show the Iran-Iraq War cost $622 billion over eight years, while U.S. national debt interest alone hits $1 trillion in 2026. The tracker aims to provide transparency on military spending as debates continue over defense budget priorities and opportunity costs in education and healthcare.
