Burn Multiple
Burn Multiple is a capital efficiency metric for startups that measures how many dollars of net cash are burned for each dollar of net new annual recurring revenue (ARR) added. It is calculated as net cash burned in a period divided by net new ARR in that same period. A burn multiple below 1x is considered excellent, 1x to 1.5x good, 1.5x to 2x acceptable, and above 2x a signal of inefficient growth. The metric is favored by growth investors because it captures the real cost of acquiring revenue, unlike gross margin or revenue growth rate examined in isolation.
Problem & Application
A SaaS startup spends $600,000 in a quarter (net of any revenue collected) and adds $300,000 in net new ARR. Burn multiple equals 2.0x -- for every dollar of new recurring revenue, the company burned two dollars of cash. A peer company adding $400,000 in net new ARR on the same $600,000 burn achieves a 1.5x burn multiple. At Series A diligence, investors will model how each company's burn multiple trends over time: a declining multiple signals improving unit economics and operating leverage; a flat or rising multiple despite scaling revenue suggests the growth is expensive to sustain. For a fractional CFO advising early-stage SaaS clients, tracking burn multiple monthly provides an early warning system before runway drops to a critical level.
In Short
Burn multiple is a critical metric for assessing the financial health of startups, providing investors and management with insights into resource efficiency and growth potential.
