Operation Epic Fury
US-Iran War Cost Tracker
This counter tracks the estimated cost of Operation Epic Fury to US taxpayers since February 28, 2026, using a phased model: ~$1.88B/day for the initial strikes (Days 1–6, per Pentagon briefing to Congress), ~$500M/day for sustained operations (CSIS/Mark Cancian), and ~$95M/day during the ceasefire standby (CSIS Apr 30: "under $100M/day") period beginning April 8. Actual costs vary with operational tempo. Figures are estimates from publicly available sources. For verified death tolls across US, Iranian, and civilian losses, see our Iran War Casualties Tracker. This spending sits on top of the regular defense budget — the peacetime baseline is tracked in US military spending in 2026.

Munitions & Interceptors
Tomahawk cruise missiles ($3.5M each), JDAMs ($80K each), Patriot PAC-3 and SM-3 interceptors. Largest cost driver — shifted from expensive stand-off weapons to cheaper gravity bombs after Day 4.
Air Operations
Fighter sorties, bomber runs, aerial refueling, tanker and cargo aircraft. Based on CBO unit operating cost rates adjusted for higher wartime tempo.
Naval Operations
Three carrier strike groups deployed (Lincoln, Ford, Bush). Nuclear-powered carriers keep fuel costs low; primary costs are aviation fuel, crew pay, and consumables.
Equipment Losses
4 F-15Es (~$100M each), 45 MQ-9 Reapers ($30-50M each, ~$1.3B total per Washington Post Aug 13, 2026 citing three US officials — up from CRS's mid-May count of 24; roughly 25% of the pre-war 185-drone fleet lost, some to comms-link failures rather than enemy fire), 1 MQ-4C Triton, 7 KC-135 Stratotankers, 1 F-35A, 1 A-10, 1 E-3 Sentry, 2 MC-130Js, 1 HH-60W — at least 42 aircraft lost or damaged per CRS report IN12692 (May 13, 2026), higher now given the updated Reaper count alone. 4 AN/TPY-2 THAAD radars (~$485M each), 1 E-7A radar aircraft ($700M, struck at Prince Sultan AB Mar 27). CSIS total-attrition estimate: $2.3–2.8B; CBS News / internal US officials put full asset losses at ~$11.9B when bases and specialized equipment included. Pentagon comptroller attributed $24B of the $29B total to equipment repair/replacement.
Intelligence & ISR
ISR platforms including MQ-4C Triton, RQ-4 Global Hawks ($176M each), satellite imagery, and cyber operations. Several drones lost over Persian Gulf.
Personnel & Logistics
Ground operations, combat pay, supply chains, medical support for ~50,000+ deployed personnel. CSIS estimates ~$1.6M/day for ground ops.
What $42.04B Could Have Funded Instead
Each dollar spent on Operation Epic Fury is a dollar not spent elsewhere. Here is what the same total would have bought in civilian programs at current unit costs. For a military yardstick instead of a civilian one, see how the same sum compares against national budgets in military spending by country.
Timeline
Vance calls conflict "not a war" as Hormuz blockade tops 87 vessels
VP Vance told reporters ahead of the Nov 3 midterm elections that he "wouldn't call it a war" and that "there is no active shooting," declining to give a timeline for ending the conflict. CENTCOM's naval blockade tally climbed to 87 vessels redirected (3 disabled, 2 boarded), up from 70 in late August. No new official Pentagon, DoD, CBO, or CSIS cumulative war-cost figure was released.
Trump confronts Hegseth over munitions shortages, calls reports "treasonous"; AEI pegs cost at $42B+
Trump reportedly confronted Defense Secretary Hegseth at Camp David over munitions-shortage reports he thought had been "fixed," then posted on Truth Social calling media coverage of dwindling stockpiles "treasonous scum" and claiming the US has "virtually unlimited" supply. Axios reported over 1,100 PrSMs and 1,100+ JASSMs have been expended, with restocking not complete until late 2026/mid-2027. Separately, a new American Enterprise Institute estimate put cumulative Epic Fury costs above $42B (led by ~$15B interceptors, ~$10B targeting-campaign costs) -- a think-tank estimate, not an official DoD/CBO/CRS release, and close to CSIS's earlier $34-42B range; COST_PHASES and CEASEFIRE_DAILY are unchanged pending an official figure.
House passes stopgap funding bill; Iran-war supplemental left out
The House passed a continuing resolution 370-48 funding the government through Dec 11, averting an Oct 1 shutdown, but the bill does not include the Iran-war supplemental Trump requested or most of the Pentagon "anomaly" funding exemptions the White House sought -- leaving Operation Epic Fury's funding gap unresolved. Not a new cumulative war-cost figure; a catch-up item missed by the prior verification pass.
CENTCOM strikes IRGC targets; Iran hits Jordan, Bahrain, Kuwait; no new cost figure
CENTCOM struck Iranian air defense, radar, maritime, mine-laying, and communications targets Sep 1, and a separate strike killed 4-5 civilians at a wedding in Sirik, Hormozgan. Iran retaliated overnight into Sep 2 on Jordan (Camp Titin), Bahrain, and Kuwait with no US casualties confirmed. Trump warned of "the biggest attack of them all" if Iran strikes again; no new official Pentagon, DoD, CBO, or CSIS cumulative war-cost figure was released for this exchange.
Trump vows "hard" response, weighs new Iran strikes; no new cost figure
Trump told Fox News the US will "hit them hard" and is weighing further strikes after the Larak Island/Jordan exchange, calling Iran a "failed nation." Iran's IRGC separately claimed (unconfirmed by CENTCOM) downing a second US MQ-9 drone over the Strait of Hormuz. No new official Pentagon, DoD, CBO, or CSIS cumulative war-cost figure was released.
Frequently Asked Questions
How much does the US-Iran war cost per day?
Costs varied by phase: ~$1.88B/day in the first 6 days (heavy Tomahawk and interceptor use per Pentagon briefing), declining to ~$500M/day as the US shifted to cheaper munitions (CSIS). Since the April 8 ceasefire, standby costs are estimated at ~$95M/day.
What is Operation Epic Fury?
Operation Epic Fury is the US military code name for joint operations with Israel against Iran, which began on February 28, 2026. Initial strikes killed Supreme Leader Khamenei. A fragile ceasefire brokered by Pakistan took effect April 8, 2026.
How much has the US-Iran war cost in total?
As of day 189, the estimated total cost is approximately $42.04B. Penn Wharton Budget Model estimates $27–28B in direct military costs through the ceasefire. CSIS reported $11.3B at Day 6 and $16.5B at Day 12.
Who is paying for the US-Iran war?
US taxpayers fund Operation Epic Fury through the Department of Defense budget. The Pentagon requested over $200B in supplemental funding, later reduced to ~$80–100B. No supplemental has been passed by Congress as of April 2026.
How does the cost compare to other wars?
At its peak rate of ~$1.88B/day (first 6 days), Epic Fury was far costlier per day than the Iraq War (~$410M/day average) or Afghanistan (~$300M/day). Total direct costs through the ceasefire (~$25B Pentagon-confirmed by Apr 28; CRS internal estimates $40–50B) make it one of the most expensive short-duration US military operations in history.
When did the Iran war start?
The US-Iran war — code-named Operation Epic Fury — began on February 28, 2026, when joint US-Israeli strikes hit Iranian military and nuclear installations. Initial strikes killed Supreme Leader Khamenei.
Is the US-Iran war over?
No. A fragile ceasefire brokered by Pakistan took effect on April 8, 2026. On April 19, 2026, the US reimposed restrictions following renewed Iranian missile activity. The status remains contested — standby costs continue to accrue while the conflict is officially paused rather than concluded.
How much does the Iran war cost per US taxpayer?
As of day 189, the US-Iran war has cost approximately $247.29 per US federal taxpayer, based on total spending of $42.04B divided across an estimated 170 million US taxpayers.
How many Americans have died in the Iran war?
Congressional Research Service (CRS R48887) has not yet released a consolidated casualty figure. See our upcoming casualties tracker for verified US service member figures — we only publish numbers that can be cross-referenced against DoD and CRS disclosures.
Has Iran closed the Strait of Hormuz?
Yes — on March 2, 2026, the IRGC announced closure of the Strait of Hormuz to US and Israel-allied shipping. See our Strait of Hormuz tracker for current status, oil price impact, and war-risk insurance rates.
What happens to the cost estimate if the ceasefire fails?
The phased model likely understates a resumption scenario. The ~$500M/day Phase 2 rate assumes US air dominance and a JDAM-dominant munitions mix. Iran is expected to reconstitute air defenses during the ceasefire (as observed in Iraq 1991–2003, Libya, and Serbia rebuilds). A return to combat would require another expensive SEAD/DEAD phase — stand-off cruise missiles, anti-radiation missiles, and interceptor expenditure against reconstituted Iranian launches — before the US could revert to cheaper munitions. First 2–3 weeks of a resumption could run 2–4x the sustained rate. This model does not forecast post-ceasefire scenarios; totals shown are historical through April 8 plus standby positioning since.
Caveat added after a reader methodology question from r/geopolitics, April 21, 2026.
Sources & Methodology
This tracker uses a phased cost model: ~$1.88B/day for Days 1–6 (Pentagon briefing to Congress), ~$500M/day for sustained operations Days 7–39 (CSIS senior adviser Mark Cancian), and ~$95M/day during the ceasefire standby period beginning April 8. All figures are estimates from publicly available sources and should be independently verified before citation.
