Warconomy compares military expenditure two ways, both from SIPRI's source-linked annual estimates: across countries for the latest year (2025, US$ billion) and over time for the world total. The three largest spenders — the United States, China, and Russia — together account for roughly half of the world total. Only the single comparable SIPRI country-expenditure metric is ranked across countries (same year, same unit, same source); the world total, real-terms change, and the NATO 2%-of-GDP count are different measures. These are annual figures, manually maintained and not real-time; military expenditure is a budget measure, not procurement, aid, or battlefield activity, and the figures are levels and direction only — not a causal attribution.
- 10 top spenders compared (SIPRI 2025, US$ billion); top 3 ≈ US$2,072.6bn combined.
- Same metric, year, unit, and source — the only basis on which these are comparable.
- Annual, source-linked, not real-time; not a causal attribution.

Totals & context (SIPRI / NATO)
- Global military expenditure: 2887 USD billion (2025 (annual))
- Global military expenditure — real-terms change: 2.9 % (2025 vs 2024, real terms)
- NATO defense spending (share at/above 2% GDP): 32 allies (2025 (all 32 allies))
These are different measures from the country ranking and must not be compared directly against a single country’s budget.

Limitations
- Currency, year, and source basis matter — compare like with like (same metric, year, unit, source).
- Military expenditure is not the same as procurement, military aid, or battlefield activity.
- Partial coverage — only source-verified spenders and totals are shown; not a causal attribution.
- Annual SIPRI/NATO estimates, manually maintained and not real-time; figures may be revised.

Key terms
- Military expenditure — A government's annual defense spending, as estimated by SIPRI. Warconomy tracks the global total, the real-terms change, top spenders, and the NATO 2%-of-GDP count.
- Time series — An append-only history of dated, source-linked snapshots for a recurring indicator. The current observation remains the source of record; snapshots add the trend. Not a live chart.
Frequently asked questions
- How do the top military spenders compare in 2025?
- By SIPRI's 2025 estimate the United States (US$954bn), China (US$336bn), and Russia (US$190bn) are the three largest spenders, together about 51% of the world total of US$2,887bn. Only this single comparable SIPRI country metric (same year, same unit, same source) is ranked.
- Is this a complete ranking of military spending?
- No. Warconomy source-links only the top three spenders and the world total; the full top-10 and regional totals are listed as data needs because they are not directly text-verifiable from the accessible SIPRI fact sheet. Coverage is partial.
- Does higher military spending mean more military activity?
- No. Military expenditure is an annual budget measure — it is not the same as procurement, military aid, or battlefield activity, and these figures are levels and direction only, not a causal attribution.
- Are these figures real-time?
- No. They are annual SIPRI/NATO estimates, manually transcribed as source-linked static values with an as-of and review date, and may be revised in future SIPRI releases.
