As explained in Flippa's guide to SaaS multiples, the Rule of 40 means that healthy software as a service (SaaS) businesses should have a revenue growth rate and profit margins that add up to at least 40%. Here are some examples:

• A SaaS business with 30% growth and a 10% profit margin meets the Rule of 40, as the total of the two is 40%.
• A SaaS business with a profit margin of 25% and growth of 20% also meets the Rule of 40, as the total is 45%.
• A SaaS business with growth of 15% and a profit margin of 15% may receive lower offers, as the total is 30%, meaning it fails to meet the Rule of 40.

The Rule of 40 is a useful way for buyers to compare the health of businesses that may have different operating models. For example, one business may have smaller margins because it’s reinvesting most of its profits in growth. Another business might have strong profits, but slower growth. Both can be considered “healthy” if they meet the Rule of 40.

According to Flippa, companies consistently beating the Rule of 40 often attract SaaS valuation multiples two to three times higher than peers with weak margins or slowing growth.

According to Flippa's H1 2026 Insights Report, completed software as a service (SaaS) sales on the platform rose by 21% in the first half of 2026 compared to the previous six months, so buyer demand is strong and growing. Now could be a good time to sell a SaaS business if it has been performing well.

In terms of performance, the following factors can indicate if your SaaS business is ready to be sold, or if it would be better to wait and do some additional preparation:

• Verified financials: Buyers will want to see month-by-month financials for at least the last 12 months, which allows them to spot trends and understand the overall health of the business.
• Low churn: The average SaaS sold on Flippa has a churn rate of 5.43%; the generally recommended figure is under 6%.
• Rising monthly recurring revenue: Buyers will want proof of steadily growing subscription revenue over the last 12 months.
• A diverse client base: Overreliance on a few high-paying customers can create risks for potential buyers.
• Clean and well-structured code: A codebase should be easy to take over by another team of developers, as needing to rebuild it from scratch can be an expensive undertaking.

As revealed in Flippa’s H1 2026 Insights Report, sales of software as a service (SaaS) businesses in the first half of 2026 achieved an average profit multiple of 2.47x, while those in the top quartile (the top 25%) achieved a profit multiple of 4.06x.

Several factors can influence the multiple a SaaS business might achieve:

• Churn rate: Churn is the percentage of customers who cancel their subscriptions over a given period. A low churn rate, usually less than 10%, demonstrates strong customer retention and satisfaction, as well as stable recurring revenue.
• Growth of annual recurring revenue (ARR): SaaS businesses with ARR growth of 40% or more often achieve higher valuations.
• Profit margins: Earnings before interest, taxes, depreciation, and amortization (EBITDA) is widely used as a measure of profit arising from day-to-day operations. SaaS businesses with an EBITDA of more than 20% often achieve higher multiples, as they’re viewed as being efficient and financially stable.
• The Rule of 40: The Rule of 40 is used to describe the relationship between the previous two factors (growth and profitability), stating that when the two are added together, the total for a healthy SaaS business should be 40% or more. This accounts for the fact that a strong business might have high growth but low profits, or high profits but low growth. Depending on the exact circumstances, both situations might still be attractive to buyers.
• Customer acquisition cost (CAC): Customer acquisition cost refers to the average amount a business spends to win one new customer. It’s often compared against customer lifetime value (LTV), which is the total amount an average customer spends before cancelling. The most attractive SaaS businesses often have a CAC to LTV ratio of 1:3 or better.

As highlighted in Flippa’s guide to software-as-a-service (SaaS) multiples, earnings before interest, taxes, depreciation, and amortization (EBITDA) are often expressed as a percentage of annual revenue (known as the EBITDA margin). An EBITDA margin of more than 20% is usually viewed more favorably, as it suggests a business is efficient and financially stable.

For example, a SaaS business with annual revenue of $500,000 and an EBITDA of $125,000 has a margin of 25%, which is above that 20% benchmark.

In some situations, an EBITDA margin of less than 20% can still attract strong valuations. The Rule of 40 combines profitability (EBITDA margin) and revenue growth, and it requires that the two percentages add up to at least 40%.

Take a SaaS business that has reinvested much of its profits in attracting new clients. It may have an EBITDA margin of 10%, but a growth rate of 35%. The two add up to 45%, so under the Rule of 40, the business may still be very attractive to potential buyers.

Valuations of software-as-a-service (SaaS) businesses are primarily driven by income, profitability, growth, and future potential. Marco Reeves, Flippa’s Regional Director for Asia-Pacific, confirmed this in the recent H1 2026 Insights Report, stating that: “Buyers are not valuing categories; they are valuing revenue quality, durability, and growth defensibility within them.”

When determining the future viability of a SaaS business, buyers may consider the following factors:

• Churn: The percentage of customers leaving each month is known as churn, and buyers generally prefer a rate of less than 6%. The average SaaS business sold on Flippa has a churn rate of 5.43%.
• Growth: Buyers look for an increase in monthly recurring revenue (MRR) over time, as this indicates that the business has a positive trajectory.
• Customer diversification: A SaaS business that relies on a few high-paying customers can be viewed as a risk to potential buyers, as losing just one or two of those customers could wipe out the profitability of the company. As a result, buyers prefer a more diverse customer base.
• Independence: An overreliance on the current owners can reduce the value of a SaaS business, as that could impact stability and profitability when the new owners take over.

As explained in Flippa’s guide to software-as-a-service (SaaS) mergers and acquisitions, owners who begin preparing their business 12-18 months in advance of a sale often achieve higher multiples, as this gives them time to stabilise and document their financials, document their processes, reduce any dependencies on the current team, and reduce technical debt.

Here’s a brief rundown on each of those areas:

• Cleaning up financials: Buyers will look for at least 12 months of profit and loss statements (provided on a month-by-month basis), and they’re most interested in any positive or negative trends that appear over time.
• Addressing churn: Churn refers to the number of customers who cancel each month, expressed as a percentage of the number of customers the business had at the start of that month. Flippa’s data shows that reducing churn from 8% to 5% can increase the multiple of a SaaS business by 0.3x or more.
• Reduce dependencies: A business with an overreliance on its current owners will be viewed unfavorably by potential buyers, as it may require a significant additional investment once they take over. To reduce such dependencies, document all processes, ensure the codebase is clean and can easily be taken over by a new team of developers, and try to limit the need for current owners to intervene in daily operations.
