Methodology {#methodology}

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

• Paddle 2024 SaaS Metrics Benchmark Report, 28,000 subscription businesses.
• OpenView 2024 SaaS Benchmarks Report, 2,100 B2B SaaS companies.
• Bain and Company SaaS Benchmarks 2023, 1,400 companies between $5M and $500M ARR.
• ProfitWell SaaS CAC Report 2023 and SaaS NPS Report 2023, 3,200 and 2,800 B2B SaaS companies respectively.
• The Starr Conspiracy B2B Marketing Effectiveness Study, 2024, a proprietary survey of 412 B2B SaaS marketing leaders across HR tech, MarTech, FinTech, and vertical SaaS, fielded Q1 to Q2 2024, with a 4.8% margin of error at 95% confidence.

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.
