On Saturday, Feb. 28, Americans woke up to find their country at war with Iran. Breaking news alerts carried word that the United States had joined Israel in an unprecedented joint military operation aimed at overturning the Iranian government. The human cost is already jarring: one week in, Al Jazeera’s live tracker counts over 1,300 dead in Iran, at least 11 in Israel, nine in Gulf states, and six American soldiers. But for millions of Americans already struggling through an affordability crisis, a different and urgent question is forming: what will this war cost their families at the pump, in the store, and in their economic futures?
We know that wars are costly. Having extricated ourselves from protracted Middle East conflicts just three years ago, we have clear reference points — which are not reassuring. The Costs of War Project at Brown University’s Watson Institute estimates that from late 2001 through fiscal year 2022, the U.S. spent or obligated $8 trillion on post-9/11 wars: $5.8 trillion in direct costs and at least $2.2 trillion in future veterans’ care through 2050. Every dollar in that accounting was a dollar that did not go toward schools, bridges, or health care.
These numbers reflect a long campaign, advocates of this war will say. President Trump has promised resolution in weeks, perhaps months — not years. His supporters point to Venezuela, where a targeted strike deposed a dictator, or to the June 2025 strikes on Iran’s nuclear program, as models of swift, decisive action. The math tells a different story.
Operation Midnight Hammer, the June 2025 Iran strikes, alone cost an estimated $2.04 billion to $2.26 billion, according to the Costs of War Project. The regional operations — Yemen, sustainment, Israel support — cost $4.8 billion to $7.2 billion. The January-February 2026 naval buildup added another $450 million to $650 million. In total, from October 2023 through September 2025, the U.S. spent between $9.65 billion and $12.07 billion on military activities across the wider Middle East. These costs came before a single shot was fired in this new war. These are dollars not spent on health care, child care, or the rising prices Americans keep asking policymakers to address.
There is a cost beyond the spending that comes from buying bombs, and Americans are already paying it. Over the course of about a week, oil prices surged 43% to over $100 a barrel — their highest in years. As of March 9, gas hit a nationwide average of $3.48 per gallon. When President Trump delivered his State of the Union two weeks ago, gas stood at $2.92, down from $3.11 at his January 2025 inauguration, a benchmark he routinely cited as proof of his economic stewardship. That ground was surrendered in under seven days. Economists estimate that every $10 rise in crude translates to roughly 25 cents at the pump. And gas pricing is not simply about commutes to school and work. It is about getting goods to consumers, which multiplies inflationary pressure across the entire economy.
Transportation disruption along the Strait of Hormuz is no incidental detail. Nearly 20% of the world’s oil passes through that narrow chokepoint, which abuts Iran directly. Iran does not need to win a war to impose economic pain on the United States and its allies — it merely needs to threaten that passage credibly. That is what we are seeing in recent fuel price fluctuation.
Critically, this war does not arrive in a vacuum. Before the first bomb dropped, American consumers were already absorbing the most significant tariff increases as a share of GDP since 1993 — an estimated average cost of $600 to $800 per household in 2026, with that figure rising toward $1,000 should remaining tariffs be made permanent, according to Yale Budget Lab’s analysis following the Supreme Court’s Feb. 20 ruling on emergency tariffs. Inflation had cooled to 2.4% in January but remained above the Fed’s 2% target, limiting its ability to respond to new economic shocks. Businesses that in 2025 absorbed tariff costs rather than passing them to customers are now widely reported to be making that shift. The war’s oil shock lands directly on top of all of it. The war did not create this affordability crisis. It accelerates one already well underway.
Beyond the debt this war will accumulate, there is the inflation it will drive into everyday goods and the fuel costs it will impose on everyone who drives to work, drops children at school, or simply needs to get somewhere. Things are going to cost more. In good times, that would be frustrating. During an affordability crisis, it is what millions can least afford — literally and figuratively.
What does this all mean in real terms for real people? For an average family making around $85,000, based on some of the current fallout of the conflict and tariff pressures, there is an effective tax of between $2,565 and $3,471 annually. For low-income families making around $30,000, the cost is between $2,143 and $2,548. It is important to note that this does not capture the full scope of costs those families face.
History offers three lessons worth holding onto. First, the United States does not have a reliable track record of quick exits from Middle East conflicts. What begins as weeks becomes years, and what is promised as surgical becomes protracted. Second, the financial costs of war consistently exceed early projections — the $8 trillion post-9/11 reckoning was not visible in the confident early days of those campaigns. Third, the burden of those costs — through inflation, debt, higher prices on everyday goods, and lives lost — falls hardest not on those who wage wars. The cost of war falls hardest on those who fill their tanks, buy their groceries, and pay their bills: the poor, the underemployed, and those least equipped to absorb rising prices and stagnant wages.
Sadly, there is a war that weary Americans are urgently waiting to see fought. It is the war on affordability. Right now, painfully few shots are being fired on that front.

Note: All figures are estimates from independent research institutions. The War Debt Share row reflects Penn Wharton’s direct military cost estimate only (~$95B ÷ 131M households); broader economic fallout — including energy, freight, and food disruption — is captured separately in the rows above and is not double-counted. The Energy Spike row is presented as a range: the low end reflects the actual AAA national average as of March 9, 2026; the high end reflects Rapidan Energy Group’s projection for sustained Hormuz disruption, corroborated by AAA’s historical crude-to-pump correlation at current oil price levels. Actual household impact will vary based on income, geography, driving habits, and the duration and resolution of the conflict.
