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.

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.
