Definition
Burn Multiple is a capital efficiency metric that divides net cash burned by net new ARR added in a given period. Introduced by David Sacks at Craft Ventures, it answers a simple question: how much cash does it cost your company to generate one dollar of new recurring revenue? A Burn Multiple of 1.5x means you spent $1.50 in net cash for every $1 of net new ARR.
The metric uses net figures on both sides of the equation. Net burn is total cash spent minus total revenue received (not just the ARR component). Net new ARR is new ARR added minus ARR lost to churn and contraction. Using net figures prevents companies from hiding inefficiency behind gross numbers. A company adding $5M in new ARR while losing $3M to churn has only $2M in net new ARR, and its Burn Multiple reflects that reality.
Burn Multiple became a defining metric of the post-2022 SaaS market. As capital became more expensive, investors shifted focus from growth-at-all-costs to efficient growth. Companies with Burn Multiples above 3x found fundraising difficult, while those below 1.5x were rewarded with premium valuations. You can model related efficiency metrics with the LTV/CAC Calculator.
Why It Matters for Product Managers
Burn Multiple connects every team's spending to revenue outcomes. Unlike sales-focused metrics like the SaaS Magic Number, Burn Multiple includes R&D and engineering costs. This means product decisions directly affect it. Every engineering sprint that does not contribute to revenue growth, retention, or efficiency increases the Burn Multiple.
PMs who understand their company's Burn Multiple make better prioritization decisions. In a high Burn Multiple environment (above 2.0x), the roadmap should bias toward features that drive near-term revenue: better conversion rates, reduced churn, faster expansion. In a low Burn Multiple environment (below 1.5x), there is room for longer-term bets on new product lines or platform investments.
How to Apply It
Calculate Burn Multiple quarterly and trend it over time. The direction matters as much as the absolute number. A company improving from 3.0x to 2.0x is on the right trajectory even if 2.0x is not yet ideal.
Steps for PM teams to influence Burn Multiple:
- ☐ Understand your company's current Burn Multiple and the trajectory
- ☐ Quantify the revenue impact of roadmap items (new ARR, retention improvement, expansion)
- ☐ Prioritize features that reduce churn and contraction since they directly improve net new ARR
- ☐ Track engineering allocation across growth, retention, and infrastructure work
- ☐ Use the RICE framework to score initiatives by revenue impact relative to effort
- ☐ Review quarterly with leadership to align product investment with efficiency targets
