The Rule of 40 is used as a comparison metric for high growth SaaS companies that are not yet profitable.
The rule states that a company's revenue growth rate plus profitability margin should be equal to or greater than 40%.
Assumptions
- Based on most recently available quarterly results
- Operating Income used as measure for profitability margin
This is a single metric viewed in isolation. It makes for useful comparison but should not be solely relied upon when performing due diligence.
