At Seed, boards want to know how long the money lasts. At Series A, the question changes. They still want to know runway, but they want to know something else first: is the burn productive?
That question has a specific answer, and it lives in one metric.
The three burn metrics
Gross burn is total cash out the door in a period — all operating expenses, payroll, software, rent, everything. It tells you the size of the machine.
Net burn is gross burn minus revenue collected. It tells you how fast you're consuming the balance. If you collect $200K and spend $400K, net burn is $200K. Runway is the bank balance divided by net burn.
Burn multiple is net burn divided by net new ARR. If you burned $400K net and added $100K in net new ARR, your burn multiple is 4.0x. You spent $4 to acquire $1 of recurring revenue.
Why boards at Series A focus on burn multiple
Net burn tells you whether you're running out of money. Burn multiple tells you whether you should be spending more or less to grow faster.
A burn multiple of 1.0x means you're spending one dollar of net cash for every dollar of new ARR. That's efficient — you're essentially funding growth from near-breakeven. A burn multiple of 5.0x means you're spending five dollars to generate one dollar of recurring revenue. That's a question: is there a path where that ratio improves, and at what scale?
The reason boards care about this at Series A — and care about it more than at Seed — is that Series A is when the company is expected to be translating investment into repeatable growth. Seed is for finding the thing. Series A is for proving you can scale it. Burn multiple is the efficiency score for that scaling.
What good looks like
There is no universal benchmark, but the ranges that matter:
- Under 1.5x: Excellent. The business is growing efficiently and could potentially be cash-flow positive at scale without dilutive capital.
- 1.5x–2.5x: Good. Typical of early-stage SaaS companies that are investing ahead of revenue.
- 2.5x–5.0x: Acceptable if declining. Boards will want to see a credible path to improvement — either from revenue acceleration or expense discipline.
- Over 5.0x: A question that needs an answer. Not always a red flag, but it needs context: what changed in the go-to-market, what's the sales cycle length, is there a large deal in the pipeline that distorts the period.
How to present it
Present burn multiple alongside net burn and runway in every board pack, in that order. The sequence matters:
- Net burn this period — the absolute number
- Runway at current burn — months remaining
- Burn multiple — the efficiency ratio
- Net new ARR — the output that justifies the burn
Then the commentary: what drove the burn multiple this period, how it compares to last period, and what you expect next quarter. A board that sees a burn multiple of 3.2x with a clear explanation of why it's 3.2x and what it will be at 18 months is a different conversation than a board that sees 3.2x with no context.
The metric answers "is the burn productive?" The commentary answers "do management understand their business?" Both are required.
