US Military Budget 2025: Where Does the Money Go?

The United States defense budget for Fiscal Year 2025 stands at $886 billion — the largest in the world and more than the next 10 countries combined. But where does all that money actually go?

The Big Picture

The $886B breaks down into five main categories:

  1. Operations & Maintenance ($296B, 33%) — The largest chunk covers day-to-day running costs: fuel, training exercises, equipment maintenance, base operations, and logistics.

  2. Military Personnel ($178B, 20%) — Pay, benefits, housing allowances, and healthcare for 1.3 million active-duty and 800,000 reserve personnel.

  3. Procurement ($170B, 19%) — Buying new weapons systems, vehicles, aircraft, ships, and equipment.

  4. Research & Development ($145B, 16%) — Developing next-generation capabilities including hypersonic weapons, artificial intelligence, space systems, and cyber tools.

  5. Other ($97B, 12%) — Military construction, defense agency operations, classified programs, and management funds.

Most Expensive Programs

The top weapons programs consuming the FY2025 budget include:

  • F-35 Joint Strike Fighter: $16.6B (the most expensive weapons program in history)
  • Columbia-class submarines: $9.6B (replacing Ohio-class ballistic missile subs)
  • Virginia-class attack submarines: $7.4B
  • B-21 Raider bomber: $5.3B (next-gen stealth bomber)
  • Sentinel ICBM: $3.7B (replacing Minuteman III missiles)

The Hidden Costs

The $886B figure only covers the Department of Defense. Total national security spending is actually much higher:

  • Veterans Affairs: $325B
  • Homeland Security: $62B
  • Nuclear weapons (DOE): $38B
  • Intelligence agencies: ~$100B (estimated)
  • True total: $1.4+ trillion

What It Means Per Taxpayer

With 157 million tax filers, the DoD budget alone costs each taxpayer $5,640 per year, or about $15.45 per day. Including all national security costs, that rises to approximately $8,900 per taxpayer.
