SaaS Rule of 40 Valuation Estimator.

## The Rule of 40

The Rule of 40 is a widely accepted metric by venture capitalists and private equity firms deciding whether a mature SaaS business is operating efficiently. It states that a company's combined growth rate and profit margin should exceed 40%.

### FAQ

**Q: How does this help valuation?**
A: It allows for tradeoffs. A startup can have a -30% profit margin as long as they are growing revenue by 70% (70 - 30 = 40). Conversely, a mature company growing at only 15% needs an incredibly healthy profit margin of 25% (15 + 25 = 40) to be considered an elite business vehicle.
