Burn Multiple measures capital efficiency: how many dollars a company burns for every dollar of net new ARR it adds. Burn Multiple = Net Burn ÷ Net New ARR, over the same period. Under 1 is considered exceptional, 1 to 2 is good to great, and above 3 is commonly read as a warning sign.
What is the Burn Multiple?
Burn Multiple is a capital efficiency metric that answers a direct question: how many dollars does a company burn to generate one dollar of net new Annual Recurring Revenue? It became a widely-cited benchmark as capital efficiency, not just growth rate, took on more weight in how SaaS companies are evaluated.
Burn Multiple formula
In words: Burn Multiple equals net burn divided by net new ARR, both measured over the same period.
Net burn is cash spent beyond what came in during the period, the same figure used to calculate cash runway. Net new ARR is the change in ARR over that period, new business plus expansion, minus churn and contraction.
Example
Over the past year, a company's ARR grew from $8,000,000 to $12,000,000, a net new ARR of $4,000,000. Over that same year, the company's net burn (cash spent beyond what it collected) was $6,000,000.
Burn Multiple = $6,000,000 / $4,000,000 = 1.5
This company burned $1.50 for every dollar of net new ARR it added that year, landing in the "great" band under the commonly cited benchmarks.
Interpreting your Burn Multiple
As a general industry convention, these bands are commonly cited:
- Under 1: exceptional. The company is adding more ARR than it's burning in cash.
- 1 to 1.5: great. Efficient, capital-light growth.
- 1.5 to 2: good. Reasonably efficient, though room to improve.
- 2 to 3: suspect. Worth investigating what's driving the inefficiency before raising more capital to fund it.
- Above 3: commonly read as a warning sign, spending heavily relative to the ARR actually being added.
Lower is better in every case, since it means less cash is required to produce the same dollar of new recurring revenue.
Why Burn Multiple doesn't reward growth on its own
This is the key difference from a metric like the Rule of 40, which explicitly adds growth rate into its score, rewarding fast growth even if it's expensive to achieve. Burn Multiple does the opposite: it only asks how much cash that growth cost, independent of how impressive the growth rate looks on its own.
A company growing extremely fast but burning enormous amounts of cash to do it can pass the Rule of 40 comfortably while posting a poor Burn Multiple. The two metrics are meant to be read together: Rule of 40 for whether the growth-and-profitability balance looks healthy, Burn Multiple for whether that growth is being bought efficiently in cash terms.
Common pitfalls
Company stage skews the comparison. An early-stage company with a small ARR base often posts a high Burn Multiple simply because fixed costs (initial engineering and go-to-market hires) are large relative to a still-small revenue base, even when the underlying execution is sound. Burn Multiple is most meaningful compared against similarly-staged peers, or tracked over time for the same company as it scales, rather than compared across wildly different stages.
A single quarter can be noisy. A large one-time expense, or a big multi-year contract landing all at once, can distort net burn or net new ARR for a single period. Most practitioners track Burn Multiple on a trailing basis (a full year, or several consecutive quarters) rather than reacting to one period in isolation.
It doesn't explain where the burn is going. A poor Burn Multiple could stem from inefficient sales and marketing spend, bloated overhead, or low gross margin eating into net burn before growth even factors in. The Burn Multiple flags that something is inefficient, but diagnosing which lever to pull requires looking at the underlying cost structure directly.
