Rule of 40 for SaaS: Calculation, Benchmarks, & Improvement Guide

The Rule of 40 measures the growth and profitability of a subscription business. Across companies of all sizes, a result of 40% or more is positive and indicates strong performance. According to McKinsey, investors reward SaaS companies that are at or above the Rule of 40 with consistently higher valuation multiples.

How to Calculate Rule of 40 in SaaS

For a rule of 40 calculation, simply add the company’s annual revenue growth rate and its EBITDA or Operating Profit Margin. The formula is:

For example, if a company has an annual revenue growth rate of 20% and an EBITDA Margin of 20%, the company’s Rule of 40 would be 40 (20 + 20). 40 or above is viewed as a good result, across companies of all sizes.

How is Rule of 40 used by SaaS companies?

Rule of 40 is commonly used for benchmarking performance. Some investors and analysts also use the Rule of 40 as a factor in valuing companies.

One indication of the Rule of 40’s adoption is the frequency with which it appears in the financial press and industry analysis. For example, Bessemer Venture Partners, a prominent venture capital firm that invests in SaaS companies, has discussed the Rule of 40 in their annual “State of the Cloud” reports.

Understanding Recurring Revenue in Rule of 40

Finance teams and CFOs often question whether the ‘Annual Revenue Growth Rate’ should be calculated as recurring revenue or total revenue. The choice can be complex, but ultimately comes down to the importance of non-recurring or one-off revenue. When it’s a small percentage of the total, it is typically excluded, whereas if it’s a core part of the offering, it’s included. If you’re still unsure, just track Rule of 40 using both definitions. Monitoring these over time frequently leads to additional insights and clarity as to which option is best. 

What is a good result?

With Rule of 40, the higher the number, the more favourable the result. This being said, there’s huge variability in top quartile results by company size.

To read the benchmarks, just find the size of your business on the horizontal axis then review the median, top quartile and bottom quartile results. 


As an example, for companies with less than $1M of ARR, median Rule of 40 scores were 22%, but top quartile performance was nearly 4x this amount at 80. For companies with greater than $50M in revenue, the 2022 median score was 30% while the top quartile was 38%. 


The most astounding conclusion is that the median result is consistently below 40 for companies of all sizes except $2.5 – $10M, while top quartile performance is consistently above 40. 

This benchmark data was compiled by OpenView in the largest 2022 benchmark report, which includes over 600 companies located across the globe.
