## Rule of 40 calculator

Add your growth rate and profit margin. If they sum to 40% or more, you're balancing growth and profitability the way healthy SaaS companies do.

The short answer Rule of 40 = **growth % + margin %**, and the bar is 40. 30% + 15% = **45%** — clears the bar. Grow fast and burn, or grow slower and profit; the sum is what matters. Revenue growth rate 30% Profit margin (can be negative) 15%

Use year-over-year revenue growth and an operating or free-cash-flow margin. Most relevant at roughly $1M+ ARR.

Beyond the number

### The Rule of 40 is a scoreboard — the spine is the field.

**Growth you can attribute.** When acquisition and revenue share a spine, you know which work and channels moved the growth half of the equation.

**Margin you can see.** Cloud and AI cost on the same record as revenue makes the margin half real — not a quarter-end finance export.

**One number, always current.** A connected spine recomputes growth and margin from live data, so the scoreboard isn't a slide you rebuild each board meeting.

FAQ

### Rule of 40 questions

**What is the Rule of 40?**

The Rule of 40 says a healthy SaaS company's revenue growth rate plus its profit margin should be at least 40%. It's a single check on the trade-off between growth and profitability — you can grow fast and burn, or grow slower and profit, as long as the two sum to 40 or more.

**How do I calculate the Rule of 40?**

Add your growth rate and your profit margin (both as percentages). For example, 30% growth + 15% margin = 45%, which passes the 40% bar.

**Which growth and margin should I use?**

Most use year-over-year revenue growth and an operating or free-cash-flow margin. Margin can be negative for fast-growing, unprofitable companies — that's expected; the rule just asks growth to make up the difference.

**Is the Rule of 40 a hard target?**

It's a benchmark, not a law — most useful at scale (roughly $1M+ ARR). Very early companies routinely miss it while investing in growth. Treat it as one health signal among unit economics, retention, and runway.

## Why AIOProductOS

- **One MCP over the whole product spine, not one tool.** 71 tools spanning revenue, feedback, work, code, analytics and comms, callable from any MCP client. Competing MCP servers expose a single product's own data; this one answers across the join, and it is listed on the official MCP registry.
- **Connected, not consolidated.** 118 connectors land Stripe, GitHub, your feedback tool and the rest onto one shared record, so a product question is a join instead of a reconciliation. You keep the tools you already run.
- **Flat plans, not a per-head meter.** Member counts are allowances, not per-seat billing, and AI teammates are included rather than metered per credit. Compare the real number for your team with the [stack cost calculator](https://aioproductos.com/tools/saas-stack-cost-calculator).
- **Nothing is plan-gated.** Every tier ships every module. The only limits are seats and agents, so the cheapest plan is the whole product.
- **Your data stays yours.** EU or US residency chosen at signup, bring your own model key, full-org GDPR export on every tier, and we never train on your data.
- **Honest onboarding.** A 14-day runway on your own data, then a 30-day money-back guarantee. No stripped free tier and no countdown trial with a meter running.
