Benchmark Methodology

Every figure on BizMetricsHQ is a range with a disclosed median — not a false-precision single number. This page documents our data sources, calculation steps, and known limitations. Last updated June 2026.

Our Methodology

Transparent, reproducible benchmarks built for trust. We publish how every number is sourced, calculated, and limited.

Experience

Real-world business data

Benchmarks reflect actual operating businesses — not theoretical models. We aggregate data from business-for-sale listings, owner surveys, and licensed industry datasets covering Main Street companies ($250k–$10M revenue).

E

Expertise

Defined, consistent metrics

Every metric uses a published definition. Revenue is gross annual sales. Margins are net profit after owner pay. Valuation multiples are based on Seller's Discretionary Earnings (SDE) — the standard for businesses under $5M.

A

Authoritativeness

Multiple verified sources

Data is cross-referenced across business brokerage platforms, SBA loan performance data, industry association reports, and IRS Statistics of Income by NAICS code. Outliers beyond 2.5× IQR are excluded.

T

Trustworthiness

Ranges, not false precision

We publish interquartile ranges (25th–75th percentile) and median values — never single-point estimates presented as facts. Sample sizes, geography, and data vintage are disclosed on every benchmark card.

How benchmarks are calculated

  1. 1

    Collect

    Gather raw data from brokerage listings, surveys, and public filings by NAICS industry code.

  2. 2

    Normalize

    Standardize owner compensation, adjust for partial-year data, and map businesses to our industry taxonomy.

  3. 3

    Filter

    Remove outliers beyond 2.5× the interquartile range and exclude businesses with incomplete financials.

  4. 4

    Calculate

    Compute median (50th percentile) and interquartile range (25th–75th percentile) for each metric.

  5. 5

    Publish

    Display ranges with sample size, geography, and last-updated date. Link to full methodology on every page.

Metric definitions

Revenue Range
25th to 75th percentile of annual gross revenue across sampled businesses in the industry.
Net Margin Range
25th to 75th percentile of net profit margin (net income ÷ revenue) after owner compensation.
Owner Salary Range
25th to 75th percentile of total annual owner compensation, including W-2, draws, and distributions.
Valuation Multiple
25th to 75th percentile of asking price ÷ SDE for businesses listed for sale. SDE = net profit + owner salary + add-backs.
Median
The 50th percentile value — half of businesses fall above, half below. More representative than mean for skewed distributions.

Limitations & disclaimers

  • Ranges reflect U.S. businesses unless otherwise noted; regional variation can be significant.

  • Valuation multiples reflect asking prices, not closed transaction prices.
  • Figures are directional benchmarks for planning — not substitutes for professional valuation or tax advice.
