The main tracker uses the Pentagon's preliminary estimate of $1 billion per day, reported by Nancy Youssef (WSJ) via a congressional official on March 4, 2026. We use this as the counter's driver because it's the most authoritative single figure available.
But we also built an independent bottom-up model to understand what's inside that number — and what might be missing from it. This page documents that model in full.
Our independent analysis suggests the Pentagon's $1B/day figure may significantly undercount true costs:
Jennifer Kavanagh (Defense Priorities) estimates the U.S. spent more than $10 billion on air-defense systems alone in the first 48 hours — that's $5B/day just for missile defense. THAAD interceptors cost $12.7M each; Patriot PAC-3 costs $3.7M each. Iran launched 2,000+ drones and 771+ ballistic missiles.
If Kavanagh's estimate is correct, interceptor costs alone are 5x the Pentagon's stated daily rate. The $1B/day figure may reflect only offensive operational costs, excluding the massive defensive expenditure.
Other indicators the true cost exceeds $1B/day:
The Penn Wharton Budget Model estimates $40B–$95B in direct budgetary costs for a conflict under 2 months. At 30 days, that's $1.3B–$3.2B/day. Their total economic impact estimate reaches $210B.
The Center for American Progress, using Brown University's Costs of War lifecycle methodology, estimated >$5B through Day 4 alone — averaging $1.25B/day and including costs the Pentagon figure likely omits (veterans' obligations, debt interest).
We built a phased daily burn-rate model from seven cost categories, using publicly available DoD data. The model produces a mid-range estimate of $155M–$380M/day depending on operational phase — capturing roughly 60–75% of true costs per CBO/RAND cost estimation guidance.
300+ aircraft in theater across 13 airframe types. Per-flight-hour costs are on a full O&S (Operations & Support) basis from DoD Comptroller data unless noted.
Combined naval and aircraft operations estimated at ~$70M/day.
High-value munitions tracked individually from reporting. Thousands of smaller munitions (JDAMs, SDBs, Hellfires, cannon rounds) are captured in the daily operational burn rate.
Specific events with attributable costs, tracked individually from open-source reporting.
Casualty figures on the main page are computed from individual incidents listed below — not a single headline number. Each incident has a unique ID to prevent double-counting. When a new report covers the same event, the existing incident is updated rather than added again.
Totals use the low-end estimate for each incident (shown with "+"). Figures marked with a range reflect uncertainty in reporting. We do not extrapolate or estimate beyond what sources report.
De-duplication rules: (1) Check if a new report refers to the same incident by date/location. (2) If a new article gives a cumulative total, reconcile against existing incidents — don't add the difference as a new event. (3) "Died of wounds" updates the existing incident.
Even our bottom-up model captures only a fraction of the true cost:
We cross-checked our model against published third-party estimates:
| Source | Their Estimate | Our Model |
|---|---|---|
| Anadolou Agency (first 24 hrs, discrete costs) | $779M | $780M |
| IPS/Nat'l Priorities Project (major equip. O&S) | $59.4M/day | ~$70M/day |
| Pentagon preliminary estimate | $1B/day | $155–380M/day |
| CAP (through Day 4, lifecycle basis) | >$5B | ~$1.8B |
| Penn Wharton (total economic) | $210B max | — |
