What is Rule of 40?

Rule of 40 is a core concept in modern B2B revenue. Here is a clear, accurate definition, why it matters, and how Ardovo handles it.

Short answer

The Rule of 40 is a benchmark for software companies stating that revenue growth rate plus profit margin should sum to at least 40 percent. A company growing 30 percent with a 10 percent margin passes. It balances growth against profitability, showing that fast growth can justify thin margins and vice versa.

Key takeaways

  • Growth rate plus profit margin should total 40 or more.
  • Balances the tradeoff between growth and profitability.
  • A quick health check for software businesses.
  • Margin can be defined several ways, so consistency matters.

Why it matters

The Rule of 40 gives investors one number to judge whether a software company balances growth and efficiency well, rather than buying growth at any cost or starving growth for margin.

How Ardovo handles it

Ardovo surfaces the growth and margin inputs from live revenue data so leaders can track their Rule of 40 score over time, and Rook can break down which segments help or hurt the balance.

Frequently asked questions

How is the Rule of 40 calculated?

Add your revenue growth rate to your profit margin, both as percentages. If the sum is 40 or higher, the company is considered to be balancing growth and profitability well.

Which profit margin should you use?

Teams use different measures, commonly EBITDA margin or free cash flow margin. The exact choice matters less than applying it consistently so the score is comparable over time.
