TL;DR
Full-scope war cost estimates — direct military, veterans care, and economic damage — are approaching $800 billion, with projections crossing $1 trillion by May if fighting continues.
MSM Perspective
CNN and Forbes published the long-term projections; almost none connected the $600 billion veterans care estimate to the concurrent Senate push to cut Medicaid.

X's fiscal hawks note that the $1B-per-day operational figure is just the entry cost — the veterans care tail on Iraq ran 20 times the original Pentagon estimate over two decades.
SAN FRANCISCO -- The United States has spent approximately $35 to $45 billion on direct military operations in the 37 days since strikes on Iran began — roughly $1 billion per day, a figure the Pentagon confirmed to Congress in mid-March. But that number, already contested and widely cited, is not the war's cost. It is the entry fee. [1]
Full-scope estimates — incorporating veterans care, military equipment replacement, economic disruption, and the fiscal drag of sustained elevated oil prices — are approaching $800 billion, according to analysts who have applied the Brown University Costs of War methodology to the current conflict. CNN reported this week that experts now estimate the war's overall cost could reach $1 trillion, with approximately $600 billion of that figure earmarked for veterans medical care over decades. [2]
The CBO has not published a standalone Iran war cost estimate — House Budget Committee Ranking Member Brendan Boyle requested one in March, and the agency has not yet responded publicly. What the CBO has confirmed is the underlying fiscal context: before the war began, the agency projected a FY2026 deficit of $1.853 trillion. The war's operational costs alone add roughly $365 billion to that figure annualized, before any supplemental appropriations are passed. [3]
The gap between the Pentagon's $1 billion-per-day operational figure and the long-term cost estimate is not accounting disagreement — it is the known structure of American war finance. The Iraq War's direct military cost peaked at approximately $190 billion. Its veterans care costs have since exceeded $2 trillion and are still accruing. [4]
Senator Elizabeth Warren pressed the CBO director on this distinction in a March 12 hearing before the Senate Finance Subcommittee on Fiscal Responsibility. The director confirmed that the agency's war cost methodology includes long-term obligations. The administration has not published its own long-range estimate. [5]
At $1 billion per day, the operational cost crosses $1 trillion in approximately 2.7 years. At the full-scope rate — when equipment replacement, veterans care projections, and economic costs are included — the $1 trillion threshold arrives considerably sooner. The CBO's projection, as reported, places that crossing in May.
