What is Burn Multiple?
Burn Multiple is a capital efficiency metric for SaaS companies, defined as: Burn Multiple = Net Cash Burned in Period / Net New ARR Added in Period. It measures how many dollars of cash are consumed for every dollar of new annual recurring revenue created. A Burn Multiple of 0.5 means the company spent $0.50 in cash for every $1 of Net New ARR: highly efficient. A Burn Multiple of 3.0 means the company spent $3.00 for every $1 of new ARR: dangerously inefficient. The metric was popularized by David Sacks at Craft Ventures and has become a standard due diligence benchmark in the 2022-2024 capital efficiency era of SaaS investing.
Burn Multiple Benchmarks
David Sacks original framework: Burn Multiple below 1x: Amazing. 1-1.5x: Great. 1.5-2x: Good. 2-3x: Suspect. Above 3x: Terrible. These benchmarks apply to growth-stage companies in the $1-50M ARR range growing at 50%+ annually. For companies growing faster (100%+ ARR growth), higher burn multiples can be justified: the efficiency question is whether the growth rate justifies the cash consumption. For companies growing slower, even moderate burn multiples may be unsustainable without significant capital raises. Burn Multiple provides a reality check that pure ARR growth metrics can miss.
Frequently Asked Questions
How does Burn Multiple differ from CAC Payback Period?
CAC Payback Period focuses specifically on sales and marketing efficiency: how long to recoup customer acquisition cost from a single customer through gross margin. Burn Multiple is more comprehensive: it captures all company cash consumption (including R&D, G&A, and every other cost center) relative to the ARR being generated. A company can have excellent CAC Payback (efficient sales motion) but a terrible Burn Multiple (if they are over-investing in engineering or general and administrative overhead). Burn Multiple provides a whole-company efficiency view, while CAC Payback provides a sales and marketing efficiency view. Both are important diagnostic metrics for different parts of the business.
How do I improve my company Burn Multiple?
Burn Multiple improvement requires either generating more Net New ARR from the same burn or reducing burn while maintaining ARR growth. Tactically: prioritize the highest-ROI growth investments and cut or delay lower-ROI initiatives, optimize go-to-market efficiency (better pipeline quality, shorter sales cycles, higher win rates), focus expansion motion to supplement new acquisition (expansion ARR costs significantly less to generate than new customer ARR), implement automation to reduce headcount growth rate relative to revenue growth, and critically evaluate R&D projects to ensure engineering investment focuses on features directly connected to retention and expansion, not speculative roadmap items.
