Wholesale Trade

The Wholesale Trade sector (NAICS 42) aggregates 165 distinct sub-industries into one benchmarking unit. At the sector level, the average net profit margin is not reported - a figure that is significantly below average. Averages at this tier can mislead because they blend high-margin specialty lines with commodity operators: Wholesale Electronic Markets and Agents and Brokers runs at 17.1%, while other sub-industries inside the same sector operate well below that headline. When you benchmark a business against a sector, always drop one level deeper to the NAICS 6-digit industry that matches your actual operations.

Scale metrics reinforce the story, and they come from two separate sources on two separate clocks. Census Bureau CBP 2023 records 29,929,176 employees across 1,910,405 establishments in this sector, while IRS SOI 2013 reports $8.7T of annual receipts from C corporation returns across the 20 sub-industries that have an SOI figure: a different population, a different year and a different denominator, so the two figures should never be divided into one another. The largest employer sub-industry is Merchant Wholesalers, Durable Goods with 3,633,921 workers, followed by Merchant Wholesalers, Nondurable Goods at 2,358,648. Understanding which sub-industries drive headcount helps identify where labor cost trends, wage pressure, and hiring competition will concentrate, all of which feed directly into the profit margin shown above.

For operators, investors, and analysts, the right move is to use this sector page as a map rather than a conclusion. Click into any sub-industry below to see its actual NAICS-6 profit margin, entity-type breakdown (sole prop vs. S-corp vs. C-corp), state-level employment concentration, and SBA lending activity. Sector-level numbers are the aggregate; the real benchmarking precision lives one layer down in the IRS SOI and Census CBP micro-data that PlainBizBench surfaces on each industry page.
