Burn Multiple Explained: The Efficiency Metric VCs Use After Series A
Growth at any cost ended in 2022. Burn multiple is how investors score whether your ARR growth is worth the cash you are spending. Here is the math, the benchmarks, and how to fix a bad number.

In 2021, investors asked how fast you were growing. In 2026, they ask how much it cost to get there. Burn multiple — popularized by David Sacks and widely used in SaaS diligence — answers: for every dollar of new ARR, how many dollars did you burn?
Burn multiple = Net burn ÷ Net new ARR (same period, annualized where needed)
Benchmarks by stage (what 'good' looks like in 2026)
| Stage | Strong | Acceptable | Concerning |
|---|---|---|---|
| Seed / pre-PMF | N/A — focus on learning | <3x if scaling | >4x without retention proof |
| Series A ($1–5M ARR) | <1.5x | 1.5–2.5x | >3x |
| Series B ($5–20M ARR) | <1.2x | 1.2–2.0x | >2.5x |
| Growth ($20M+ ARR) | <1.0x | 1.0–1.5x | >2.0x |
Context matters. A 2.2x burn multiple with 120% NRR and sub-12-month CAC payback tells a different story than 2.2x with churn rising and sales cycle lengthening. Investors triangulate — but the headline number still sets the meeting tone.
Worked example
Q2 net burn: $900K. Net new ARR added in Q2: $600K. Burn multiple = $900K ÷ $600K = 1.5x. Translation: the company spent $1.50 in net cash for every $1 of new ARR — efficient for Series A, worth explaining if growth decelerates next quarter.
Five levers to improve burn multiple without killing growth
- Cut duplicate SaaS and vendor waste — median $14K/mo recoverable at 50–200 employees
- Align hiring to revenue capacity; use comp-band gates before offers
- Improve sales efficiency (win rate, cycle time) before adding AE headcount
- Renegotiate annual contracts 60–90 days before renewal with utilization data
- Extend runway via net burn reduction so you can grow into a better multiple next quarter
Board narrative
Show burn multiple trend over 4 quarters, not a single snapshot. A team improving from 2.8x → 2.1x → 1.7x with a hiring plan tied to pipeline coverage gets more credit than one spike at 1.4x with no explanation.
Automating the inputs so the metric stays honest
Burn multiple fails when net burn comes from accounting and net new ARR comes from a CRM export from different weeks. Finance Brain syncs Stripe (revenue), QuickBooks (burn), and HubSpot (pipeline) into one workspace so board prep pulls consistent periods with cited sources.
FAQ
- What is a good burn multiple for Series A?
- Bessemer and SaaS Capital benchmarks suggest under 1.5x is strong at Series A, 1.5–2.5x is acceptable if growth is high, and above 3x raises efficiency concerns unless you are deliberately buying market share with a long runway.
- How do you calculate burn multiple?
- Burn multiple = Net burn ÷ Net new ARR (annualized). Use the same period for both — typically trailing quarter net burn divided by net new ARR added in that quarter, annualized.
- Is burn multiple the same as the rule of 40?
- No. Rule of 40 combines growth rate + profit margin. Burn multiple measures dollars spent per dollar of new ARR — a capital efficiency lens popular in 2023–2026 diligence when growth alone stopped justifying spend.
