How does burn multiple differ from CAC payback?

CAC payback measures time to recover customer acquisition cost (months). Burn multiple measures all-in capital efficiency, including R&D and overhead. CAC payback is per-customer; burn multiple is company-wide.

What's a healthy burn multiple at pre-seed?

Pre-seed companies often have burn multiple of 3-5x (acceptable since you're investing ahead of revenue). The number matters more at seed (target <2.5x) and Series A (target <2x).

Can burn multiple be negative?

Yes — if you're net cash positive (net inflow exceeds net outflow), burn multiple is negative. This is the goal for healthy SaaS at scale, sometimes called 'capital efficient' or 'default alive' state.

Burn Multiple

A capital efficiency metric — net burn divided by net new ARR. The lower the better; under 1x is excellent; over 3x is concerning.

Definition

Burn Multiple is a capital efficiency metric introduced by David Sacks. It measures how much capital a company burns to generate each additional rupee of revenue.

Formula: Burn Multiple = Net Burn / Net New ARR. Net burn is total cash outflow minus inflow (excludes one-time items); Net New ARR is new ARR added during the period (new logos + expansion - churn).

Benchmarks: under 1x is excellent (₹1 of burn produces ₹1+ of new ARR), 1-2x is good, 2-3x is acceptable in growth mode, above 3x signals inefficiency that institutional investors typically penalise.

India Context

Indian SaaS investors in 2026 use burn multiple as a primary capital-efficiency screen — the post-2022 cohort of well-run Indian SaaS targets burn multiple under 2x even in heavy growth mode. Companies with burn multiple over 4x typically fail to raise Series A regardless of ARR growth.

The metric replaces the older "growth at any cost" mindset. Burn multiple + NRR + growth velocity is the new fundability triangle.

Example

A SaaS startup adds ₹2Cr new ARR over 12 months while burning ₹3Cr net cash. Burn Multiple = ₹3Cr / ₹2Cr = 1.5x. This is "good" — efficient growth. The same company adds ₹2Cr new ARR while burning ₹7Cr: Burn Multiple = 3.5x — concerning.
