Burn multiple
The burn multiple divides net cash burned in a period by the net new annual recurring revenue (ARR) added in the same period. It answers: how many dollars of cash did the company spend to add one dollar of new recurring revenue? A lower multiple means more efficient growth. It is a startup-finance convention popularized as a capital-efficiency gauge, not an accounting standard.
What this means
Burn multiple = net cash burned in the period ÷ net new ARR added in the same period. Net burn is cash out minus cash in (excluding financing); net new ARR is the change in annual recurring revenue across the period. If a company burned $2M and added $1M in net new ARR, its burn multiple is 2 — two dollars spent per dollar of new recurring revenue.
How to read it
The burn multiple is unusual in that lower is better and it pairs spend directly with the durable output (recurring revenue) rather than a vanity output. It captures inefficiency that growth-rate or burn alone can hide: a company can grow fast while burning so much that each new dollar is expensive. The metric is a convention from startup investing — the exact treatment of net burn and the ARR window vary — and it is meaningless or negative when net new ARR is near zero or shrinking, so read it with the absolute figures.

- Net cash burned ÷ net new ARR added, same period
- Lower is better — fewer dollars per dollar of new ARR
- Undefined or misleading when net new ARR is near zero
How it appears in analytics and logs
A lower burn multiple means each dollar of new ARR cost less cash to generate — more efficient growth. A high or rising multiple means the company is spending heavily for diminishing revenue gains.
Diagnostic use case
Judge how efficiently a company converts cash into durable recurring revenue, especially when growth and spending are both high.

Common mistakes
- Reading the burn multiple as 'higher is better'.
- Computing it when net new ARR is near zero or negative.
- Ignoring how net burn is defined (financing in or out).

- Rule of 40
The Rule of 40 is a heuristic for software businesses: add the revenue growth rate (percent) to a profitability margin (percent), and the sum is the score. The convention holds that a healthy company should reach roughly 40, trading growth against profit — fast growth can justify thin margins and vice versa. It is an industry rule of thumb, not an accounting standard, and the choice of margin varies.
- SaaS magic number
The SaaS magic number relates new recurring revenue to the sales-and-marketing spend that produced it. A common form divides the annualized increase in recurring revenue in a quarter by the prior quarter's sales-and-marketing cost. It estimates how much new annual recurring revenue each dollar of go-to-market spend generates. It is a venture-finance convention with several formula variants.
- Annual recurring revenue (ARR)
Annual recurring revenue (ARR) is the annualized value of a business's recurring subscription revenue — the run rate it would earn over a year if nothing changed. It is closely tied to MRR (often MRR × 12) and is used for longer-horizon planning and contracts. ARR is a forward run-rate snapshot, not historical annual revenue, and like MRR it excludes one-off and usage charges.
