Benchmarking Insights for Manufacturing

When you read the 1.3% net profit margin for Manufacturing, the number only becomes actionable when paired with scale. This industry sits inside the broader Manufacturing sector and reports $279.8B of aggregate annual receipts across 5,454 federal tax returns. Owners comparing their own books should read the margin as a midpoint — smaller operators typically run several points below the aggregate because fixed overhead (rent, software, insurance) consumes a larger share of lower revenue bases, while the typical establishment here generates $51.3B per year. Treat the industry figure as a ceiling calibrated by businesses that have already achieved operating leverage.

Labor economics tell the second half of the story. Census CBP shows 3,570 active establishments employing 354,914 workers, averaging 99.4 employees per location and paying $83,673/yr per employee annually. Indiana leads the geographic distribution of employment, with Ohio and Pennsylvania rounding out the top three concentrations. Headcount density matters because thin-margin industries only clear the cash-flow bar when establishments reach the staffing level where fixed costs amortize — a useful cross-check against the margin line above.

Capital access is the third lens. SBA 7(a) and 504 approvals for this industry totaled 319 loans worth $308 million between FY2020 and FY2025, supporting 5,036 jobs at origination. The average ticket size — $966K — signals the typical capital gap operators bridge when expanding. The Huntington National Bank ranks as the most active SBA lender serving this NAICS code. Use this alongside the IRS and Census figures to decide whether your own plan should target operational efficiency, workforce expansion, or financed growth.
