What is burn multiple?

Burn multiple is the metric that exposed the growth-at-all-costs era for what it was. It answers one brutal question. How much cash did you set on fire for every dollar of new revenue?

Definition
Burn multiple is net cash burned divided by net new ARR added over the same period. Burn $2M to add $1M of net new ARR and your burn multiple is 2. The lower the number, the more efficiently your growth is bought. It is the cleanest single read on capital efficiency.

Coined by David Sacks, the burn multiple became the metric of the post-2021 reset. It captures in one number what growth rate alone hides. A company growing 80% means little if it burned $4 for every $1 of new ARR to get there. The same growth at a burn multiple under 1 is a different company entirely.

How to calculate it

How to calculate burn multiple.

Burn multiple = net burn / net new ARR
Net burn: cash out minus cash in over the period, the real cash consumed.
Net new ARR: new plus expansion ARR minus churned ARR in the same period.
Period: usually a quarter or a year, matched on both sides.

Benchmarks

What a healthy burn multiple looks like.

The scale is simple and unforgiving. Under 1 is elite, you add more ARR than you burn. 1 to 1.5 is good. 1.5 to 2 is fine for an early or fast-scaling company. Above 2 gets questioned and above 3 is the zone investors now walk away from.

Stage shifts the bar a little. A seed company spending to find product-market fit gets some grace. A Series C company at a burn multiple of 3 does not, because by then efficiency should be improving, not deteriorating. The trend matters as much as the level.

How to improve it

Three levers that improve a burn multiple.

01

Grow net new ARR, not just new ARR

The denominator is net of churn. Every dollar of churned ARR makes your burn multiple worse even if burn holds flat. Retention is a capital-efficiency lever, not just a revenue one.

02

Cut the burn that does not buy ARR

Audit spend against new ARR, not against headcount. The fastest improvement usually comes from killing programmes that consume cash without moving the recurring base.

03

Make expansion carry the growth

Expansion ARR is the cheapest new ARR there is, because you are not paying fresh CAC for it. A base that expands lifts net new ARR while burn stays put, which pulls the multiple down fast.

Common questions

Questions about burn multiple.

How do you calculate burn multiple?+

Divide net cash burn by net new ARR over the same period. Burn $2M to add $1M of net new ARR and the burn multiple is 2.

What is a good burn multiple?+

Under 1 is elite. 1 to 1.5 is good. 1.5 to 2 is acceptable for fast-scaling early companies. Above 2 draws questions and above 3 is a red flag for most investors in 2026.

What is the difference between burn multiple and burn rate?+

Burn rate is how much cash you spend per month, an absolute number. Burn multiple ties that burn to the new ARR it produced, which makes it a measure of efficiency rather than speed.

Why do investors care about burn multiple?+

Because it strips the spin out of growth. Fast growth bought with reckless burn is fragile. A strong burn multiple shows growth the company can sustain without constant fresh capital.

Does burn multiple use gross or net new ARR?+

Net new ARR, which is new plus expansion minus churn. Using gross new ARR flatters the number by ignoring the revenue you lost, which defeats the point of the metric.

Burning too much for the growth?

If the burn multiple is creeping up, the leak is usually in retention or in spend that never touches ARR. Book a 30-minute audit and we will find it. No sales sequence.
