Iran War Cost Tracker — Live Estimate of U.S. Taxpayer Spending

Based on the Pentagon's preliminary estimate of $1 billion per day

per gallon (regular) — up $0.45 since the conflict began

Pre-conflict (Feb 26) $2.96

Current national avg $3.41

Increase +$0.45 (+15.2%)

The national average jumped nearly 27 cents in a single week as the Iran conflict threatens the Strait of Hormuz, through which 20% of the world's daily oil moves. AAA reports the fastest weekly increase since Russia's invasion of Ukraine in 2022.

The Real Cost May Be Higher

Missile Defense Alone: ~$5 Billion / Day

Jennifer Kavanagh of Defense Priorities estimates the U.S. "easily" spent more than $10 billion on air-defense systems in the first 48 hours. Iran launched 2,000+ drones and 500+ ballistic missiles (CSIS). CSIS separately estimates interceptor costs at $1.2B–$3.7B for the first 100 hours.

THAAD interceptor $12,700,000 each

Patriot PAC-3 $3,700,000 each

Iranian Shahed-136 drone $35,000 each

Cost ratio (interceptor vs. drone) 106 : 1

Stockpile Depletion

THAAD interceptors (Dec 2025) 534

SM-3 interceptors (Dec 2025) 414

Used in June 2025 (12-day war) 100–150 THAAD, 80 SM-3

THAAD production rate 96/yr → 400/yr (ramping)

PAC-3 production rate ~600/yr → 2,000/yr (ramping)

Full depletion at current usage 4–5 weeks

In June 2025's 12-day war, the U.S. expended up to 30% of its THAAD stockpile and 80 SM-3s. Production cannot keep pace: even at quadrupled rates, replacing 150 THAAD interceptors takes nearly 5 months.

At sustained conflict consumption, the entire U.S. interceptor stockpile could be exhausted in 4–5 weeks — creating vulnerabilities for NATO, Ukraine, Taiwan, and Japan, all of which depend on U.S. defense supplies.

This tracker exists because the public deserves real-time transparency about the cost of military operations — not just after-the-fact reports years later. The counter uses the Pentagon's own preliminary estimate of $1 billion per day. Independent analyses suggest the true cost may be significantly higher.
