What is a good Rule of 40 score?
The Rule of 40 benchmark is refreshingly simple: 40 is the pass mark. What varies is how companies get there, through growth, through margin, or a blend.
At different stages, the mix shifts. Early on, growth dominates the score and margins are negative; as companies mature, margin carries more of the load.
Short answer
A good Rule of 40 score is 40 or higher, meaning revenue growth rate plus profit margin clears the bar. Elite software companies reach 50 to 60. A score below 40 signals you are neither growing fast enough nor profitable enough to compensate. Above 40 is the line investors watch at scale.
Key takeaways
- 40 or higher is the healthy benchmark.
- Elite SaaS scores 50 to 60.
- Early stage leans on growth; mature stage leans on margin.
- Most meaningful past roughly 10M in revenue.
What good looks like by stage
A high-growth early company might score 40 through 55 percent growth and negative 15 percent margin. A mature company might score the same 40 through 15 percent growth and 25 percent margin. Both pass, by different routes.
Public SaaS leaders often sustain scores in the 50s. Consistently scoring below 40 at scale usually draws pressure to either reaccelerate growth or expand margin, because the market prizes the balance.

Ardovo tracks your Rule of 40 score over time and decomposes it into growth and margin, so you see which lever is carrying it. Rook models how a change in either would move the score, helping you plan the tradeoff.
Frequently asked questions
What is a good Rule of 40 score?
40 or higher passes; elite software companies reach 50 to 60. Below 40 signals an imbalance where growth and profitability together are not strong enough. The benchmark is most meaningful at scale.
How do elite companies score above 50?
By combining strong growth with real profitability, or by growing exceptionally fast. A company growing 40 percent with a 15 percent margin scores 55. The best sustain both levers at once as they scale.
Does the Rule of 40 apply to early startups?
Less usefully. Very early companies have extreme growth and burn, so the ratio is noisy. It becomes a meaningful benchmark once revenue is past roughly 10,000,000 dollars and the business is scaling.
