Burn Multiple — the SaaS investor's #1 metric in 2026
Burn Multiple — the SaaS investor's #1 metric in 2026
In 2020 David Sacks (Craft Ventures, ex-COO of PayPal) published a short essay that reshaped how SaaS companies are evaluated. He proposed one simple formula:
> Burn Multiple = Net Burn / Net New ARR
How many dollars a company burns to generate $1 of new annual recurring revenue.
It strips away every marketing illusion. It doesn't matter how much growth you have — what matters is how efficiently you buy that growth.
Why Burn Multiple matters more than ever right now
Before 2022, in the ZIRP era (zero interest rate policy), venture money was almost free. Funds handed capital to companies with a Burn Multiple of 5x, 8x, sometimes 15x — as long as growth was there. "Grow at all costs" was the mantra.
That's over. Funds now treat capital efficiency as table stakes:
| Period | Acceptable Burn Multiple for Series A | ||
|---|---|---|---|
| 2019–2021 | up to 3-5× | ||
| 2022–2023 (correction) | up to 2× | ||
| 2024–2026 | <1.5× — otherwise raising a round is hard |
The formula in detail
Net Burn = cash expenses − cash revenue over the period (usually a quarter).
Net New ARR = New ARR + Expansion ARR − Churned ARR − Contraction ARR.
It's typically measured per quarter, then normalized. Example:
- Net Burn in Q1: $500,000
- Net New ARR in Q1: $600,000
- Burn Multiple = 500 / 600 = 0.83× → excellent
David Sacks' benchmarks
| Burn Multiple | Rating | ||
|---|---|---|---|
| <1× | Amazing (PayPal-level) | ||
| 1–1.5× | Great | ||
| 1.5–2× | Good | ||
| 2–3× | Suspect | ||
| >3× | Bad — the company burns capital inefficiently |
Why is Burn Multiple better than Magic Number?
Magic Number (Scale Venture Partners) only measures Sales & Marketing efficiency:
Magic Number = (Net New ARR × 4) / S&M spend per quarter
Great for optimizing the funnel. But it ignores R&D, G&A and operations — which is most of an early-stage SaaS company's spend.
Burn Multiple covers everything. It's the final efficiency figure for the whole company. Magic Number optimizes a part; Burn Multiple optimizes the whole.
In a typical SaaS business:
- 40% of burn = S&M
- 35% = R&D
- 15% = G&A
- 10% = COGS (if not already in gross margin)
Magic Number sees 40%. Burn Multiple sees 100%.
4 levers to improve Burn Multiple
1. Sales & Marketing efficiency
Lower your CAC:- Organic channels (SEO, content, referrals) instead of paid
- ICP focus — don't chase segments with poor conversion
- Self-serve onboarding for SMB (removes sales cost)
- Optimize funnel CR — every +10% compounds
2. Expansion ARR (NRR-driven)
Every existing-customer dollar is cheaper than a new one:- Seat-based or usage-based pricing
- Tiered features → natural upgrade paths
- Account management for high-ARR customers
- Customer health scoring for proactive expansion
3. R&D efficiency
- Fewer parallel streams — focus on 1-2 ICPs
- AI / no-code for PRD/QA automation
- A senior-heavy team (3 seniors > 6 mids in SaaS)
4. Churn reduction
Every point of churn roughly doubles the CAC you need to compensate:- Onboarding — the first week drives 80% of future churn
- Annual prepay contracts (mathematically cut churn ×12)
- Health scoring + proactive outreach
Real-world example
A SaaS startup with:
- ARR: $2M, 8% MoM growth
- Net Burn: $250k/mo (=$750k/quarter)
- Net New ARR per quarter: $500k
Burn Multiple = 750 / 500 = 1.5× → Good, but room to improve.
Scenario "get to 1.0×":
- Cut burn by $250k/quarter = -33% (headcount cuts? Outsource ops?)
- OR accelerate ARR growth to $750k/quarter = +50% (new channel? Better pricing?)
- OR a mix: -15% burn + +20% ARR ≈ 1.05×
Use the calculator below to model your own scenario.
When Burn Multiple is MISLEADING
The metric isn't a silver bullet. Ignore it or read it carefully when:
1. Pre-revenue stage — denominator = 0, the metric is infinite
2. One large contract skewed the quarter — normalize over a rolling 4 quarters
3. You're investing in a long-horizon product (deep tech, hardware-software) — a short-term Burn Multiple is bad by design
4. Seasonal businesses — Q4 e-commerce vs Q1 SaaS
Bottom line
If you're a SaaS founder in 2026, Burn Multiple is the number an investor asks about first in the next-round meeting. Know yours, optimize it below 1.5× per quarter, and fundraising gets an order of magnitude easier.
