Setting up multiple companies to separate business interests can seem very straight forward. There are however important considerations. We explore the implications of owning too many companies.
Understanding the Rule of 40 for SaaS Businesses: A Key Metric for Success
18 July 2024
Digital & Tech
The Rule of 40 is a critical benchmark for Software as a Service (SaaS) businesses.
Offering a simple yet powerful way to evaluate a company’s performance and potential for long-term success, this metric is particularly important to investors and company owners as it balances growth and profitability, providing a comprehensive view of a company’s health.
Why is this important?
Just recently we have seen the Xero (a leading SaaS accounts software provider) CEO, Sukhinder Singh Cassidy, state that:
‘This result shows we’re doing what we said we’d do.
We’ve delivered a strong and profitable FY24 result and Rule of 40 outcome, demonstrating our commitment to balancing growth and profitability.
We have a clear and focused strategy to win on purpose, and Xero is positioned well as we move into FY25.’
The Rule of 40 is therefore not just another metric conjured up by accountants but a practical metric used by major SaaS businesses.
This can easily be applied to smaller SaaS businesses as well.
We have discussed metrics in detail in a previous blog SaaS Company Valuation Guide and detail how Friend & Grant can help a SaaS business set up systems to generate essential KPIs.
These can then be used to improve performance and ultimately increase the company valuation.
What is the Rule of 40?
The Rule of 40 states that the combined value of a SaaS company’s revenue growth rate and its profit margin should be at least 40%.
This formula is:
Revenue Growth Rate + Profit Margin ≥ 40%
For instance, if a company is growing at 30% annually and has a profit margin of 15%, the sum is 45%, surpassing the Rule of 40 benchmark.
This rule can be adapted to various stages of a company’s lifecycle, focusing on the right balance for early-stage, high-growth companies or more mature, profitable ones.
What is growth rate and profit margin?
It simple terms you need to calculate your current annual recurring income and compare to that 12 months ago.
This can be done by measuring your monthly recurring income every month and multiplying by 12.
Growth Rate = (MRR Current x 12 – MRR Prior Year x 12) ÷ MRR Prior Year x 12
In respect of profit margin most users will calculate the EBITDA (earnings before interest, tax, depreciation and amortisation) and divide this by turnover.

Why is the Rule of 40 Important?
Balanced Perspective
The Rule of 40 encourages a balance between growth and profitability.
High growth often comes at the expense of profitability and vice versa.
By considering both, investors and owners can gauge whether a company is scaling efficiently without compromising financial stability.
Investor Confidence
For investors, the Rule of 40 serves as a quick check to assess investment potential.
A company meeting or exceeding this benchmark is typically seen as a more attractive investment because it indicates robust growth potential and efficient operation.
Strategic Decision-Making
Company owners can use the Rule of 40 to guide strategic decisions.
It highlights the need to strike a balance between reinvesting for growth and maintaining a healthy profit margin, ensuring long-term sustainability.
Comparative Benchmarking
The Rule of 40 allows for easy comparison among SaaS companies.
It acts as a standard measure, enabling investors and executives to compare performance across the industry.
Summary
In conclusion, the Rule of 40 is an essential metric for SaaS businesses, providing a clear and balanced measure of success that is crucial for investors and company owners alike.
By focusing on both growth and profitability, this rule helps ensure sustainable growth and attracts investment, ultimately driving the company’s long-term success.
