Caution: You might be burning too much cash relative to your growth, or growing too slowly for your burn.
What is the Rule of 40?
The Rule of 40 is a popular benchmark for Software-as-a-Service (SaaS) companies. It suggests that a healthy company's combined growth rate and profit margin should exceed 40%.
This metric is widely used by Venture Capitalists (VCs) and Private Equity firms in 2026 to evaluate startups. It acknowledges that early-stage companies can be unprofitable if they are growing very fast, while mature companies can have slow growth if they are highly profitable.
