Answer-first summary
SaaS Magic Number: SaaS Magic Number is a sales efficiency metric that approximates how efficiently sales & marketing spend converts into new recurring revenue.
Formula
Magic Number
Magic Number = (Net New ARR in period × 4) / Sales & Marketing Spend in prior period
- Net New ARR: Net new recurring revenue annualized
- Sales & Marketing Spend: Fully-loaded spend, often prior quarter
Net new ARR $300k in Q2, S&M spend $600k in Q1 → magic number=(300k×4)/600k=2.0.
Directional Magic Number Ranges
Benchmarks vary widely by industry, ACV, go-to-market motion, geography, and measurement method. Treat these as directional ranges, not targets.
| Segment | P25 | P50 | P75 | Notes |
|---|---|---|---|---|
| Early GTM | 0.3–0.6 | 0.6–0.9 | 0.9–1.3 | — |
| Efficient growth | 0.7–1.0 | 1.0–1.3 | 1.3–2.0 | — |

- Shorten sales cycle.
- Improve pipeline quality and targeting.
Common pitfalls
- Using inconsistent ARR definitions.
- Ignoring expansion/churn components.

FAQ
- Is 1.0 the goal?
- ≈1.0 is often considered healthy. Above 1.0 indicates efficient growth; below 0.5 suggests GTM inefficiency or long payback.
- Quarterly vs monthly?
- Most commonly quarterly due to sales cycles; monthly can be too noisy.
