SaaS Magic Number & Go-To-Market Sales Efficiency Calculator

Venture Capital Metrics: The Bessemer SaaS Magic Number

Developed by Bessemer Venture Partners, the SaaS Magic Number is the gold-standard metric for deciding whether a subscription business should accelerate marketing spend:

• Magic Number > 1.0x (Pour on the gas): The business generates over $1.00 of high-margin recurring ARR for every $1.00 invested in sales; aggressive expansion is warranted.

• 0.75x to 1.0x (Good efficiency): Healthy unit economics; continue steady scaling.

• < 0.50x (Red flag): Sales cycles are too long or customer churn is eroding growth; do not increase sales headcount until the funnel is repaired.
