Two official figures for what the military costs

Ask what the United States spends on its military and the federal government gives two official answers, from the same API, for the same year. In fiscal year 2025 the budget heading called National Defense carried $1.30 trillion of outlays. The Department of Defense reported $501.6 billion of obligations on awards.

Both are correct. They answer different questions, and a figure quoted without saying which it is answers one of them for a reader who asked the other.

What the budget heading counts

The federal budget is organized under 18 functions, headings that group spending by purpose rather than by who spends it. In fiscal year 2025 National Defense was the 3rd largest by outlays: $1.42 trillion obligated and $1.30 trillion paid out, reported by 10 agencies.

It is a purpose, not a department. The Department of Defense carried 95.7% of those outlays, $1.25 trillion. The Department of Energy reported $38.1 billion under it, 2.9% of the heading, and the Department of Justice $12.4 billion. A reader who takes National Defense to mean the Pentagon's budget is reading a heading as a department.

What the award figure counts

An award is a contract, grant, loan or direct payment to a named recipient, reported one award at a time. The Department of Defense's awards in fiscal year 2025 came to $501.6 billion. Contracts were $491.8 billion of it, 98.0%, and grants $9.4 billion.

This is the only part of the record that says who received the money, and the same record the rankings of defense contractors and of what the military buys are built from. It is also the figure most easily mistaken for the whole.

The two on one basis

The heading and the awards differ in two ways at once: one counts outlays and the other obligations, and one spans 10 agencies while the other is a single department. Taking both out leaves one comparison the record supports: obligations, the Department of Defense only, in the same year.

The department's budget accounts obligated $1.45 trillion in fiscal year 2025, summed across every budget heading it reports under. Its awards were $501.6 billion, 34.6% of that. The other $949.7 billion was obligated and not reported as an award.

Neither report says what that $949.7 billion was. Award records cover money committed to a recipient under one of the instruments above, and anything a department obligates in another way appears in its account totals and nowhere in its awards. Both reports stop at that line.

Which figure answers which question

For what the country spends on defense, the heading is the answer: $1.30 trillion of outlays across every agency the budget counts as defense. It is the heading the budget itself is organized by.

For who the military pays, the awards are the answer: $501.6 billion, each with a recipient. Quoted as the cost of the military, it falls $949.7 billion short of what the department's own accounts obligated.

What this does and does not establish

The two department totals come from two different reports, one built from budget accounts and one from individual awards. The publisher does not reconcile them, and this brief does not either: 34.6% is one published total set against another, not a measured split of the same money.

Obligations are commitments made in the year, and outlays are payments made in it. A commitment made in one fiscal year can be paid in a later one, so the two measures of the same heading differ in any year and neither is the other one late.

Nothing here is a statement about whether any of it was well spent. A heading, a department's accounts and its awards are ways of counting, not verdicts.
