What multiple does a SaaS business sell for?

Buyers of SaaS businesses typically start from a different number than buyers of most small businesses. Instead of applying a multiple to seller’s discretionary earnings, a growing subscription business is often discussed in terms of a multiple of annual recurring revenue, because a company reinvesting heavily in growth can be genuinely valuable while showing modest or even negative current profit. That framing only works, though, once a buyer trusts the recurring revenue is durable, which is where the real work of a SaaS valuation actually happens.

Growth rate and net revenue retention set the ceiling

How fast annual recurring revenue is growing, and how much of the existing customer base’s revenue is retained and expanded rather than lost to cancellations, are the two figures that move a SaaS multiple the most. A business with strong net revenue retention — meaning existing customers are spending more over time, not less — supports a materially stronger multiple than one with the same current revenue but customers who are quietly shrinking their usage or churning out, because the second business needs constant new sales just to stand still.

The rule of forty is a shorthand, not a formula

Investors and buyers commonly reference a combined growth-rate-plus-profit-margin threshold, often called the rule of forty, as a rough gut check on whether a SaaS business is growing efficiently enough to justify its multiple, rather than growing at the expense of profitability with no path to either. This kind of shorthand is a useful sanity check in a conversation, not a formula to apply mechanically to a specific business, since the right way to weigh growth against margin still depends on the business’s stage, market and capital position.

Gross margin and customer concentration set the floor

A SaaS business with strong gross margin after hosting, support and payment-processing costs has more room to reinvest in growth and still be profitable, which buyers generally reward with a stronger multiple than a business with the same revenue and thinner margins. Revenue concentrated in a small number of large customers works against the multiple as well, since losing even one account can move the growth and retention numbers a buyer is relying on.
