Burn Multiple

A "good" Burn Multiple varies significantly by company stage and growth rate. As a general rule:

• Early-stage (Seed to Series A): 1.5x - 3x is acceptable as you're proving product-market fit
• Growth-stage (Series B+): <1.5x is ideal, with best-in-class companies achieving <1x

However, context matters enormously. A company burning 3x to grow 200% YoY may be making a smart investment, while the same 3x multiple with 50% growth signals problems. High-growth companies often justify higher Burn Multiples temporarily, especially when:

• Investing ahead of growth (hiring sales teams before they're fully productive)
• Building infrastructure for scale (engineering, systems, operations)
• Expanding into new markets or segments

The key is trajectory: your Burn Multiple should improve over time as you achieve scale efficiencies, not worsen. If it's consistently rising, investigate whether you're losing product-market fit or becoming operationally inefficient.

While these metrics all measure efficiency, they focus on different aspects:

• Burn Multiple: Holistic, company-wide efficiency. Captures total capital consumption (all expenses) relative to ARR growth, including sales, marketing, product development, operations, and overhead. Best for overall health assessment.
• CAC Payback Period: Sales & marketing efficiency only. Measures how long it takes to recoup customer acquisition costs, focusing specifically on go-to-market effectiveness. Best for evaluating S&M spend efficiency.
• Magic Number: Sales & marketing ROI. Shows how much ARR growth you generate per dollar of S&M spend (calculated as Net New ARR / S&M Spend in prior quarter). Best for quarter-over-quarter S&M efficiency.

The advantage of Burn Multiple is comprehensiveness—a company might have great Magic Number and CAC metrics but terrible Burn Multiple due to engineering bloat, excessive overhead, or operational inefficiency. Conversely, you might optimize Burn Multiple while missing that your S&M efficiency is declining. Use all three together for complete visibility: Magic Number and CAC Payback for go-to-market, Burn Multiple for overall capital efficiency.

Yes, and these scenarios reveal important business conditions:

Negative Burn Multiple occurs when:

• Net burn is negative (profitable/cash-generating) AND net new ARR is positive → Excellent! You're growing profitably. The metric becomes less meaningful here since you're no longer burning capital.
• Net burn is positive (burning cash) AND net new ARR is negative (shrinking) → Crisis. You're losing customers while spending money. The negative number mathematically understates the severity—you're burning cash without growth.

Undefined/Infinite Burn Multiple occurs when:

• Net new ARR is zero or near-zero → Common pre-revenue or during plateaus. Focus on absolute burn rate and runway instead. Your goal is to achieve any positive ARR growth to make the metric calculable.

Practical guidance: When Burn Multiple becomes negative or undefined, pivot to these metrics:

• Pre-revenue: Track absolute monthly burn and months of runway
• Declining ARR: Focus on churn analysis, customer health, and potentially path to profitability
• Profitable growth: Celebrate, but track CAC Payback and Growth Rate instead

The goal is to maintain a positive, declining Burn Multiple that eventually reaches zero at profitability.
