Growth at all costs. Acceptable if NRR and LTV:CAC are strong, but watch the burn multiple. The market has less patience for this than in 2021.

Origin and Purpose

Brad Feld introduced the Rule of 40 to solve a recurring debate in SaaS investing: is a fast-growing, money-losing company better than a slow-growing, profitable one? The answer: it depends on the combined score. A company growing at 100% but burning 50% of revenue (score: 50) is healthier than one growing at 10% with 15% margins (score: 25). The Rule of 40 provides a single number to evaluate this tradeoff.

The rule works because SaaS companies can choose where they sit on the growth-profitability spectrum. Increasing S&M spend typically increases growth rate but decreases margin. Cutting costs improves margins but slows growth. The Rule of 40 asks: regardless of where you chose to sit, is the combined output healthy?

Beyond 40: The Elite Tier

While 40 is the baseline for healthy SaaS, the best companies consistently score 60+. These companies have found operating leverage: they grow fast AND generate margin. In the 2026 market, companies scoring 60+ include those with strong NRR (expansion drives growth without proportional cost), PLG motions (low CAC at scale), and vertical dominance (pricing power). The Rule of 40 is a floor, not a ceiling. The ceiling is as high as your execution allows.

Frequently Asked Questions

What is the Rule of 40 in SaaS?
The Rule of 40 states that a healthy SaaS company's revenue growth rate plus EBITDA margin should equal or exceed 40. For example, a company growing at 80% with a -20% EBITDA margin scores 60, which is above the line. A company growing at 20% with 15% margins scores 35, which is below. Brad Feld popularised the concept as a way to evaluate whether a company balances growth investment with profitability. It prevents companies from over-indexing on either extreme.
What is the Rule of 60?
The Rule of 60 is the higher bar for elite SaaS companies. While the Rule of 40 represents a healthy baseline, companies scoring 60+ typically trade at significantly higher revenue multiples. These companies have found the rare combination of strong growth AND meaningful profitability. Examples include Datadog, CrowdStrike, and Veeva Systems at their peak. The Rule of 60 separates good SaaS companies from great ones.
How does Rule of 40 affect valuation?
Companies scoring above 40 trade at materially higher revenue multiples. Based on public SaaS company analysis in 2026: below 40 typically commands 3-6x revenue, 40-60 earns 8-15x, and above 60 can achieve 15-30x+. This valuation premium exists because the Rule of 40 signals a company that can both grow and generate returns, reducing investor risk. The multiple difference between 35 and 45 can be 2-3x, making the Rule of 40 line extremely consequential.
Should growth or profitability contribute more to Rule of 40?
Investors generally prefer growth-weighted Rule of 40 scores. A company at 60% growth and -20% margin (score: 40) is valued higher than one at 15% growth and 25% margin (score: 40), even though the Rule of 40 score is identical. Growth has option value: a fast-growing company can choose to become profitable, but a slow-growing profitable company cannot easily reignite growth. That said, the 2024-2026 market has revalued profitability, and companies with scores driven primarily by negative margins face more scrutiny.
What is the best way to improve Rule of 40 score?
If your score is growth-led (high growth, negative margins): focus on gross margin improvement and operating leverage. As revenue scales, fixed costs should shrink as a percentage. If your score is margin-led (profitable but slow growth): invest the margin into demand generation, product-led growth motions, or new market expansion. The most common path to improvement is not cutting costs but improving sales efficiency (magic number) so each dollar of spend generates more growth.
