Burn multiple = net burn ÷ net new ARR. It measures how many dollars you burn to add one dollar of ARR. Below 1.0 is elite; above 2.0 is trouble.
Burn multiple, popularized by David Sacks, measures capital efficiency in a single number: how many dollars of cash you burn to add one dollar of net new ARR. It replaced growth-at-all-costs thinking after the 2022-2023 correction and is now the primary lens investors use to evaluate whether a company deserves more capital.
Burn multiple = Net burn ÷ Net new ARR. Measured over a trailing 12-month or quarterly period. Example: $12M burn, $8M net new ARR = 1.5x burn multiple. Net new ARR = new logo ARR + expansion − churn − contraction (essentially the numerator of NRR growth, plus new logos).
Elite (< 1.0x): capital-efficient growth, deserves more funding at premium terms. Great (1.0-1.5x): healthy efficiency, standard growth-stage venture profile. Ok (1.5-2.0x): acceptable if growth rate is >100% or the market is very large. Suspect (2.0-3.0x): capital efficiency needs immediate work, hard to raise at good terms. Bad (>3.0x): existential — either fix or fail.
Two levers: reduce burn or increase net new ARR. Reduce burn: freeze hiring in non-critical functions, cut experimental initiatives, optimize infrastructure, extend vendor payment terms. Increase net new ARR: prioritize highest-ROI acquisition channels, reduce churn (lower churn = higher net new even at same gross), raise prices, focus sales on highest-conversion segments.
During the 2020-2021 ZIRP era, growth-at-all-costs meant companies with 200% growth and 5x burn multiples raised at premium valuations. Post-correction, those same profiles couldn't raise at any price. Burn multiple normalizes growth by capital consumed — a company growing 60% at 1.0x is more investable than one growing 120% at 3.0x, because the former can survive without more funding.
