What the database shows
Across employment-meaningful industry records, the middle reported pre-tax profit margin is 5.2%. The middle half of the comparison runs from 3.0% to 8.5%. Those are aggregate industry benchmarks, not a forecast or a target margin for an individual company.

Profit margin is calculated as net income divided by total receipts in the IRS source. Payroll and employment are supplied by Census County Business Patterns. The portal does not estimate suppressed or missing values.
How to read this national report
The source tables aggregate businesses by NAICS industry. They are useful for comparing industry-level financial and operating patterns, but they do not describe a specific company, worker, state, or local market. A reported margin can differ with company size, ownership structure, accounting treatment, geography, and the mix of firms inside an industry code.
The most defensible use is a two-step comparison: find the closest NAICS benchmark, then read its source context and limits alongside the national distribution. The percentile tool can place a margin in that same reported distribution without implying that the result predicts a business outcome.
Method, source, and limits
This page queries the live PlainBizBench database at request time. Profit-margin figures come from IRS Statistics of Income business tax statistics and are calculated as reported net income divided by reported total receipts. Employment and establishment totals come from Census County Business Patterns. The national quartiles use industry records with reported margins, NAICS level 3 or deeper, and more than 10,000 employees so very small records do not drive the headline range.
IRS and Census releases have different publication schedules and coverage rules. The report preserves those source boundaries rather than blending, interpolating, or projecting data. Read the methodology and source notes before reusing a figure, and cite the underlying government datasets where their original publication is the appropriate source.
