$20.1T of revenue, 14%-15% of GDP. How to read the Fortune 500 against the rest of America.

Same units, different things

Rule. Revenue counts a part every time it is sold along the supply chain; GDP counts only the value each producer adds, so revenue is compared with gross output and business receipts, and value added with GDP.

Gross output and tax-return receipts are the economy's revenue line; GDP is its value-added line. The Fortune 500 appears once on each line. Value added here is approximated from the records as labor cost + depreciation & amortization + operating profit ($6.7T worldwide). That misses taxes on production that firms expense, counts acquired-intangible amortization BEA would not, and uses template-estimated labor for many firms, so treat it as a +/- 15% figure even before the US-share range.

Who produces the $30.9T

Rule. What the 500 do not capture is most of the economy: private and small firms, partnerships and sole proprietors, foreign-owned US affiliates, nonprofits, households and government all add value the list never sees.

U.S. GDP for CY2025 split by the sector that produces it (BEA NIPA table 1.3.5 and 1.14), with the Fortune 500's US value added carved out of the corporate slice. The bracket over the blue segment is the low-to-high estimate.

How much of the 500 is in America at all

Rule. Fortune 500 revenue and headcount include foreign subsidiaries, so only the US share belongs in a comparison with US GDP or US employment.

The US share comes from each company's geographic revenue segments where its filing has them (337 companies, 73% of revenue). Where the filing lumps the US into "North America" the US is assumed to be 80%-95% of it, and 60%-90% of "Americas". For the other 163 companies (mutual insurers, co-ops, private firms, segments not split by geography) the assumption is a range from their measured sector peers' US share up to 100%. Revenue is booked by customer location, which is not quite where the work is done; headcount uses the same share for want of a better one.

Where the 500 are the economy, and where they are a rounding error

Each bar is a BEA industry's CY2025 (annual average) value added; the blue part is the Fortune 500 companies we map to it (US share, est.), the gray part everyone else. Companies are assigned whole to their largest segment's industry, so conglomerates blur the edges.

One private-sector worker in 6 works for the 500

Headcounts in the records are worldwide; the US part is estimated with each company's US revenue share, which likely overstates US jobs at companies that do their labor-heavy work offshore and understates it at exporters. BLS payroll counts jobs (a person with two jobs counts twice); the household survey counts people. The Census figure is the biggest employers of all kinds, private and foreign-owned, in March 2023.

A separate layer, not a bigger company

Rule. Government purchases are part of GDP, but transfers re-enter as household spending (and partly as Fortune 500 revenue), so government is shown beside business, never stacked on top of it.

CY2025 (annual average), BEA NIPA. Federal grants to states ($980B) are counted once, where states spend them. The three pieces sum to $11.7T, more than total government expenditures of $11.1T, because purchases include depreciation of public capital, which the expenditure total nets out; subsidies and transfers abroad are left off.

Stocks you owe, flows you add

Rule. Debt is a stock, not a flow: it is set against other stocks, and only the year's net new borrowing, deficit and interest are set against flows like revenue or GDP.

Outstanding debt securities and loans at end of 2025 (Q4 level) (Federal Reserve Z.1, Treasury). The Fortune 500 slices are each company's latest balance-sheet total debt from FMP (471 of 472 tickered companies, retrieved 2026-10-03), worldwide and consolidated, so they are not a strict subset of the domestic Z.1 totals. Banks, brokers and the mortgage GSEs are kept apart from operating companies: their liabilities fund lending books.
