Why these tools are free

RevenueLab is ad-supported. The calculators stay free because display ads and a small set of relevant affiliate links cover hosting and the time it takes to keep 2026 benchmarks current. There's no premium tier, no "unlock advanced features," and no point at which we ask for an email to see your result.

Every tool documents its formula and cites the source for any benchmark (IRS Publication 15-T, SSA bend points, YouTube Partner Program disclosures, Mediavine/Raptive RPM reports, SaaS Capital benchmarks, etc.) so you can verify the math.
