What is SaaS?
SaaS, or Software as a Service, is a cloud-based application that provides Software to users. It works similarly to how streaming platforms work. You need to get a subscription to access the services rather than purchasing them for once, and you can pay as you go, ensuring flexibility in the system.
This renting procedure of the SaaS application provides an all-in-one solution that enhances accessibility and convenience, allowing users to connect and use the required services.
The most popular SaaS applications are Google Workspace, Zoom, Netflix, and Microsoft Office 365.
What is Rule of 40 in SaaS?
The Rule of 40 in SaaS is a rule of thumb that determines the performance of a software company based on combined growth rate and profit margins. According to this Rule, a SaaS company’s growth rate added to the Profit Margin should equal or exceed 40%. It is believed that this Rule measures the balance between the company’s growth and profitability.
The Rule of 40 has become an important parameter to measure the level of performance of a SaaS company. It provides a means for investors and shareholders to compare between the software companies so that they can invest wisely in the business.
So, if a SaaS company meets or exceeds the Rule of 40, it is more likely to attain a secure position in the market and attract investments, thereby achieving long-term growth and higher profits.
Calculation of the Rule of 40
There are two main components for calculating the Rule of 40. They are the Growth rate of the company and the Profit margin. So, the formula becomes:
Growth Rate + Profit Margin ≥ 40%
Let’s examine the following points to learn how these two components are measured.
- For calculating the Rule of 40, the growth rate is measured by its monthly recurring revenue(MRR), or we can use annual recurring revenue(ARR). So, the formulas are:
MRR= Total number of active accounts * Average Revenue per account
ARR= MRR * 12 (for months)
Hence,
Growth rate (Current Year Value – Previous Year Value) / Previous Year Value
- The EBITDA margin for the same growth rate period measures profit margin.
Profit Margin = EBITDA margin = EBITDA / Revenue
So, using the above formulas, you can easily calculate the Rule of 40 for any SaaS company.

Importance of the Rule of 40 in SaaS
The Rule of 40 has significant benefits for SaaS companies.
- Balanced Evaluation: This “Financial” metric assists investors and stakeholders as they evaluate a SaaS company holistically, factoring sales growth at first dollar positive and revenue retention against CAC in the same equation. If the combined number is greater than or equal to 40, a stock can still be considered healthy even if it has very high growth but no profitability.
- Growth vs. Profitability: SaaS companies are particularly troubled by the balance between growing aggressively and needing to achieve profitability. The Rule of 40 recognizes this, offering a rule of thumb to embrace the trade-off and offer up an acceptable range for businesses in different stages of development.
- Investor Confidence: The Rule of 40 is a litmus test to help assess & triage SaaS companies based on their business model and growth rate so that the investor can become confident in his assessment. Reach or exceed this benchmark; for the most part, you have a business that can sustainably scale.
Conclusion
The Rule of 40 is a powerful rule that equally measures the financial health of SaaS companies using both growth and profitability. This report is helpful for investors, executives, and stakeholders in Stock Exchanges. SaaS companies that master and apply the Rule of 40 have a compass to help them navigate the stormy seas of their business model, plot the course for strategic growth, and chart locks in their path toward long-term success.
