The “Rule of 40” is a simple figure for assessing the efficiency of a SaaS software companies growth and thus the quality of the business model. We track the current Rule of 40 stocks list and update our table on a daily basis. The key figure is calculated using the following formula:
Rule of 40 Score = sales growth rate + profitability
Both the sales growth and profitability are expressed as percentages. If the sum of these two percentage values is greater than 40, the company makes the Rule of 40 list. See more about our Rule of 40 calculation on the About page.
All Rule of 40 data is available on the API page.
