What the Retail Trade Sector Numbers Reveal

The Retail Trade sector (NAICS 45) aggregates 56 distinct sub-industries into one benchmarking unit. At the sector level, the average net profit margin is 3.8% — a figure that is below the national median. Averages at this tier can mislead because they blend high-margin specialty lines with commodity operators: Retail Trade runs at 5.4%, 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. Census Bureau CBP 2023 records 6,863,044 employees across 1,224,300 establishments in this sector, with $1.2T of annual receipts flowing through the IRS SOI filings. The largest employer sub-industry is Retail Trade with 1,108,365 workers, followed by Retail Trade at 831,551. 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.
