The 40-Day War's Economic Bill — U.S. "Spending" Over $45 Billion, Nearly $1 Billion Daily

A 40-day ongoing war has cost the United States over $45 billion in direct military expenses, averaging nearly $1 billion spent each day. As the conflict prolongs, the U.S. Department of Defense has applied to Congress for an additional $200 billion in war funding. Against the backdrop of a national debt reaching $39 trillion, these astronomical figures are fueling growing economic concerns within the United States.

1. U.S. War Bill: $45 Billion Spent in 40 Days

According to estimates from the Iran War Cost Tracker website, as of April 6, the total U.S. military expenditure on Iran has exceeded $42 billion. After 36 days, about $1 billion was spent daily. With the conflict extending to 40 days, this number has surpassed $45 billion. Other agencies' estimates confirm this scale — analysts point out that the high-intensity spending on the U.S.-Iran conflict averages between $500 million and $900 million per day, forcing the U.S. to urgently request an additional $200 billion in war funding.

Calculations suggest that this military operation, lasting over a month, costs roughly the equivalent of an additional $2.5 to $3.8 per American per day. Air, sea, and ground operations are the main expenses — air operations are estimated to cost $30 million daily, maritime operations about $15 million per day. U.S. Defense Secretary Hagel has gone to Congress to request an extra $200 billion in war funds, while the U.S. national debt has already reached $39 trillion.

2. Battlefield Consumption: The Huge Contrast Between High Costs and Limited Results

Massive spending has not yielded the expected "quick victory." Former President Trump initially claimed to destroy Iran’s missile industry, eliminate the Iranian Navy, prevent nuclear weapons development, and dismantle proxy networks, but after 40 days, the Iranian regime still exists, and the Strait of Hormuz remains effectively blocked.

The U.S. military has also paid a price. A total of 365 U.S. personnel have been injured in military operations against Iran, with 13 fatalities, including six soldiers killed in Iranian attacks in Kuwait, one who died after being wounded in Saudi Arabia, and six who died in a crash of a U.S. refueling aircraft. On April 3, a U.S. F-15E fighter jet was shot down inside Iran. The U.S. deployed a large force to rescue two pilots, but during the rescue, an A-10 attack aircraft, a C-130 transport plane, multiple helicopters, and MQ-9 drones were also lost.

According to the UK’s International Institute for Strategic Studies, rescue operations involved MC-130J special operations transport aircraft and C-295 transport planes, typically used for ground infiltration missions, suggesting the U.S. may be preparing for deeper ground assaults. If ground fighting truly begins, war costs could escalate at an even more alarming rate.

3. Economic Backlash: Rising Oil Prices and Inflationary Pressures

The war’s backlash on the U.S. economy has already begun to show. Since the conflict erupted on February 28, Brent crude oil prices have surged significantly, reaching a high of $119.52 per barrel. After news of a ceasefire, international oil prices sharply declined — U.S. WTI futures fell 14.56% to $96.50 per barrel; Brent futures dropped 11.85% to $96.32 per barrel. Nonetheless, oil prices remain well above pre-war levels.

Domestic gasoline prices in the U.S. have increased by nearly 40%, and inflation pressures continue to mount. JPMorgan Chase CEO Jamie Dimon warned that if oil prices stay high, the U.S. economy could enter recession. Meanwhile, Trump’s approval rating at the end of March has fallen to 35%, the lowest since his return to the White House. Demonstrations have swept across 50 states, and over 20 lawmakers from both Democratic and Republican parties, including Senate Minority Leader Schumer, have called on cabinet members to invoke the 25th Amendment to remove Trump from office.

4. U.S. Adjusts War Budget Expectations

Notably, with a ceasefire agreement in place, the Trump administration is expected to significantly cut back on Iran war funding requests. According to Jin10 Data, the U.S. may reduce its initial plan of approximately $200 billion for Iran-related military expenses to between $80 billion and $100 billion. This adjustment signals two things: first, that the ceasefire temporarily halts large-scale military operations; second, that facing domestic political pressure from massive expenditures, the White House is reevaluating the war budget.

Meanwhile, Defense Secretary Hagel has stated that U.S. forces will ensure Iran complies with the ceasefire and are prepared to resume operations at any time. The Trump administration is expected to firmly demand Iran’s removal of nuclear materials and a halt to uranium enrichment during negotiations. This means that even if the war temporarily pauses, the diplomatic and economic game on the negotiation table will still require substantial investment.

Summary: The 40-day war has cost the U.S. over $45 billion — enough to build 15 large sports stadiums in Washington or provide a full year of free school lunches for 40 million children nationwide. However, the Iranian regime remains in power, and the blockade of the Strait of Hormuz continues to threaten global energy transportation. The Trump administration is cutting war budgets and signaling a ceasefire, but whether this is the start of a "peace agreement" or a prelude to a more costly "long-term conflict" remains uncertain. The Islamabad talks in 14 days will provide an initial answer.
