Burn multiple compares how much net cash a software company uses with the net new recurring revenue it adds over a period. It is a capital-efficiency diagnostic: a higher ratio means more cash was consumed for each unit of new ARR, but the ratio alone does not explain why.
Formula and example
A common formula is: burn multiple = net cash burn during the period ÷ net new ARR during the same period. If a company burns $2 million of cash and adds $1 million of ARR, the burn multiple is 2.0. Some teams use net new revenue instead of ARR or define burn as operating cash flow; the chosen numerator and denominator should be stated.
Read the components first
Net cash burn is not the same as accounting loss. ARR is a forward-looking contract measure, while cash burn reflects cash movements. Timing matters: sales and marketing spend may occur months before an annual contract closes, and annual prepayments can change cash without changing the underlying margin or retention.
- Use consistent periods, currency, and treatment of financing or one-time items.
- Separate new-customer ARR from expansion when evaluating acquisition efficiency.
- Review gross margin, retention, and contract quality alongside the ratio.
- Compare a rolling period when quarterly bookings are lumpy or sales cycles are long.
- Investigate both spending and growth before deciding to reduce investment.
Avoid treating a single ratio as a verdict
A high burn multiple can reflect early product investment, an intentional market entry, or weak conversion from spend to durable revenue. A low multiple can look attractive while hiding poor retention or underinvestment in future pipeline. Segment the trend by motion, cohort, and spend category where data allows.
Use burn multiple to ask where capital is converting into durable ARR and what evidence would change the plan. It is most useful alongside cash runway, payback, gross margin, and customer retention—not as a stand-alone benchmark.
