Plain definition
Burn multiple divides net cash burned over a period by net new ARR created in that same period. It is a capital-efficiency indicator for a growth business: how much cash it consumed to add one unit of annual recurring run rate. The numerator needs a consistent cash definition and the denominator needs a matched ARR movement definition.
It is not a universal target and it is not a substitute for runway, gross margin, retention, or cash-flow quality. A low multiple can arise from under-investment or a temporary collection event; a high multiple can be appropriate during a deliberate but well-funded build.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
Suppose a company burns of net cash in a year and adds of net new ARR in that same year. The burn multiple is 3.0 times: 600,000 ÷ 200,000. If net new ARR is near zero or negative, the ratio is not a useful positive efficiency score and should be explained rather than forced into a ranking.
Management should pair the result with cash runway, cohort retention, sales payback, and the investments that drove the burn.
| Net cash burned | |
|---|---|
| Net new ARR | |
| Burn multiple |
Keep the time periods and currency aligned. Do not divide one quarter of cash burn by an annual ARR movement.
Why it matters
The measure connects growth headlines to the cash sacrificed to produce them. It exposes when ARR growth is being purchased at a rate the business cannot finance.
Practical consequence
Define net cash burn and net new ARR, reconcile both to cash and subscription bridges, and use matching periods. Split the result by material growth investment where possible. Review a trend, not one isolated period, alongside runway, GRR/NRR, CAC payback, and funding availability.
