The Indicator from Planet Money
Episode Summary: “How much is the Iran war costing us?”
Date: March 18, 2026
Hosts: Ricky Mulvey & Darian Woods
Guests: Linda Bilmez (Harvard Kennedy School), Mark Cancian (retired Marine Colonel), Nita Crawford (Costs of War Project)
Overview
This episode examines the multifaceted and often underestimated economic costs of the ongoing U.S. conflict with Iran, known as Operation Epic Fury. The hosts, joined by experts in defense spending, war finance, and public budgeting, break down why war expenses are so difficult to track in real time, the lessons learned from past conflicts (especially post-9/11), and the numerous long-term financial burdens that extend far beyond the battlefield.
Key Discussion Points & Insights
1. Estimating the Daily Cost of War
- Initial Estimates:
- The Center for Strategic and International Studies originally estimated the daily cost of Operation Epic Fury at around $900 million ([00:25]).
- More recent Pentagon estimates have doubled that figure to approximately $1.9 billion per day (Darian Woods, [00:39]).
- Quote:
“These estimates are the tip of an ice—”
—Linda Bilmez, [00:52]
- Why Estimates Change:
- The type and volume of munitions used were greater than expected, and more damage to U.S. bases increased expenses (Mark Cancian, summarized by hosts, [02:09]).
- Budgetary Workarounds:
- Munitions are not part of the current Department of Defense recurring budget; after ordnance is used, the military must request additional funding from Congress (Ricky Mulvey, [02:32]).
- Quote:
“After the US drops a bomb in Iran, the military says that's not a part of our regular budget and now we need to immediately pay to replace these bombs...”
—Ricky Mulvey, [02:32]
2. Long-term and Underestimated Costs
- Historical Underestimation:
- War costs are nearly always underestimated at the outset due to optimism about duration and outcomes (Linda Bilmez, [03:25]).
- Past Example:
- The Iraq war was initially estimated by the Bush administration at $50 billion, but the real spending was closer to $3 trillion (Nita Crawford, [03:48]).
- Veterans’ Care:
- Caring for service members post-conflict is a “staggering” cost that often exceeds initial expectations (Linda Bilmez, [04:04]).
- Quote:
“The amount of accrued disability benefits, not counting health care, just disability benefits that we have already promised to veterans is $7.3 trillion.”
—Linda Bilmez, [04:39])
3. Environmental Costs
- Military Emissions:
- The U.S. Department of Defense emitted the equivalent of 47 million metric tons of CO2 in 2024—more than many countries’ annual totals (Linda Bilmez, [05:03]).
- Operational Impact:
- Moving fleets, aircraft, and strikes on oil facilities have significant and lasting environmental consequences (Nita Crawford & hosts, [05:17]–[05:24]).
- Quote:
“Bombing oil facilities creates long-term environmental damage.”
—Ricky Mulvey, [05:24])
4. How the U.S. Funds War Today
- Debt-Financed Conflicts:
- Unlike pre-9/11, the U.S. now borrows almost entirely to finance wars, rather than raising taxes or cutting government spending ([05:55]).
- Future Burden:
- This debt carries interest, shifting the fiscal burden to future generations (Linda Bilmez, [06:01]).
- Economic Debate:
- Mark Cancian notes that some economic theories (Ricardian equivalence) see no practical difference between funding via debt or taxes ([06:07]).
- Linda Bilmez disagrees, arguing taxes make the cost more visible to citizens and help shape democratic “buy-in” ([06:31]).
- Quote:
“People experience the cost of anything in a different way if they are asked to pay taxes than if they incur debt.”
—Linda Bilmez, [06:31]
- Historical example:
- President Truman emphasized tax payments to support wars, linking fiscal responsibility directly to national commitment ([06:54]).
- Quote:
“If this is important enough that we have to go to war, then it's important enough we have to pay for it.”
—recalls President Truman, Linda Bilmez, [06:54])
5. Enduring Fiscal Effects: Military Budget Expansion
- Ratcheting Up Base Budgets:
- Wars are followed by large increases to Pentagon base budgets that are rarely reduced, even after the conflict ([08:05]).
- Example: President Trump recently requested a $1.5 trillion military budget—a 50%+ increase ([07:25]).
- Quote:
“Once that gets added into the Pentagon's annual budget, it stays there pretty much forever.”
—Linda Bilmez, [08:05])

Tone
Informative and brisk, the conversation is accessible but grounded in data and expert analysis, emphasizing the complexity and far-reaching consequences of wartime fiscal decisions for American taxpayers.
Episode Takeaway
The economic impact of war is far greater than the daily headlines suggest. Costs extend well beyond bombs and planes to include ballooning veterans’ obligations, environmental fallout, and future interest payments—burdens that shape American life for generations. Even when war spending seems “temporary,” it often permanently expands the footprint of U.S. defense budgets.
