40法则计算器公式

## How to Calculate the Rule of 40

### Formula

**Rule of 40 Score = Revenue Growth Rate (%) + Profit Margin (%)**

The Rule of 40 is a SaaS industry benchmark that balances growth against profitability. A company growing at 60% with a -20% margin scores 40, just like one growing at 10% with a 30% margin. The idea is that fast-growing companies can afford to burn cash, while slower-growing ones must compensate with strong margins. Scores above 40 are considered attractive to investors.

计算示例

A SaaS company growing revenue at 30% year-over-year with a 15% EBITDA margin.

  1. Rule of 40 = 30% + 15% = 45
  2. Distance from 40 = 45 - 40 = +5
  3. The company exceeds the Rule of 40 by 5 points.
