• Organized for quick extraction by metric and segment.

What it is not:

• A definitions or formulas page.
• An interpretation or advisory layer.

Use this if you are:

• Defending budget in a board or finance review.
• Building a board narrative around growth efficiency.
• Diagnosing whether a gap sits in CAC, retention, or operational efficiency.

Methodology {#methodology}

This hub aggregates 18 benchmarks from five primary sources collected between 2022 and 2024.

Curation: where sources disagreed on a metric, the higher-sample dataset was used. The Starr Conspiracy study data was validated by removing responses missing required CAC or ARR fields, capping outliers at the 1st and 99th percentiles, and reconciling ACV-band self-classification against reported revenue. Self-reported data from The Starr Conspiracy's study is flagged in each entry.

Limitations: geographic scope is primarily North America and Western Europe. CAC definitions vary across sources, for example CAC per new logo versus CAC per $1 new ARR; entries name the definition used. Self-reported data is subject to respondent definition and recall bias. Benchmarks are directional and depend on definitions and segment fit.

Refresh cadence: quarterly. Last updated November 2024.
