Rule of 40
A rough health check for growth-stage software: revenue growth rate plus profit margin should exceed 40.
Example
60% growth with a −15% margin gives 45 — acceptable. 15% growth with a −40% margin gives −25, which is not.
Important
It is a benchmark for companies with real scale, not a target for a company with twenty customers. Applying it early produces the wrong decisions in both directions.
