What is burn multiple — and what's a good one in 2027?
Burn multiple is the single cleanest measure of capital efficiency in a venture-backed software business: Net Burn divided by Net New ARR. If you burn $4M in a quarter and add $2M of net new ARR, your burn multiple is 2.0 — meaning every $1 of new recurring revenue cost you $2 of cash. Lower is better. In 2027, anything under 1.0 is exceptional, 1.0–1.5 is good, 1.5–2.0 is OK, 2.0–3.0 is suspect (where most growth-stage SaaS actually lives), and above 3.0 is a red flag investors will not ignore.
TL;DR
- Formula: Burn Multiple = Net Burn / Net New ARR. The denominator includes expansion minus churn, so retention problems surface immediately.
- 2027 benchmarks (Craft Ventures + Bessemer): <1.0 amazing, 1.0–1.5 good, 1.5–2.0 OK, 2.0–3.0 suspect, >3.0 bad, >5.0 restructure.
- Origin: David Sacks at Craft Ventures popularized it in Q3 2022, post-ZIRP, as the explicit replacement for the magic-number era of "growth at all costs."
- Why it won: ties directly to cash runway, harder to game than CAC payback, and survives investor scrutiny at every stage from Series A through pre-IPO.
- Three levers to fix it: cut burn (headcount discipline), grow net new ARR (pipeline plus win rate), or reduce churn (NRR improvements hit numerator and denominator at once).
The Math and Craft's Benchmark Bands
The math is intentionally trivial, and that is part of why it spread. Take net burn for the quarter — operating cash out minus operating cash in, ignoring financing — and divide it by net new ARR for the same quarter. Net new ARR is the change in your ARR base: new logos plus expansion (upsell, cross-sell, seat growth) minus churn (downgrades plus logo loss). One number, easy to compute from any reasonably clean finance and RevOps stack, and almost impossible to obscure with accounting choices.
The benchmark bands published by Craft Ventures and corroborated by Bessemer's State of the Cloud 2024 are the de facto industry standard heading into 2027. Below is the table that shows up in nearly every Tier 1 board deck today.
| Burn Multiple | Craft Ventures Label | What it Means in Practice |
|---|---|---|
| < 1.0 | Amazing | Top decile. You are printing efficient growth and can raise on your terms. |
| 1.0 – 1.5 | Good | Healthy. Investors will compete to lead. |
| 1.5 – 2.0 | OK | Acceptable but watched. Many Series B companies sit here. |
| 2.0 – 3.0 | Suspect | The honest median for growth-stage SaaS. Boards push for a path under 2.0. |
| 3.0 – 5.0 | Bad | VCs flag in IC memos. Next round at risk or at a haircut. |
| > 5.0 | Restructure or die | Board mandates layoffs, leadership change, or strategic alternatives. |
The worked example everyone uses on the whiteboard: a Series B company burning $4M per quarter and adding $2M of net new ARR posts a 2.0. That puts them right on the bubble — not bad enough to panic, not good enough to raise easily. The same company two quarters later, after holding burn flat at $4M while growing net new ARR to $2.8M, sits at 1.43 — squarely "good." That is the entire reason this metric replaced everything else: a five-minute calculation tells the board exactly how much room the company has.
Why Burn Multiple Replaced Magic Number Post-2022
Before 2022, the dominant VC efficiency lens was the magic number (net new ARR divided by sales and marketing spend from the prior quarter, annualized). It worked in a ZIRP world where capital was effectively free and the only question was whether growth was reproducible. When rates moved and the IPO window slammed shut in Q2 2022, the question changed overnight from "is this growth repeatable" to "how long until you run out of cash."
Sacks published the burn multiple framework in his Q3 2022 essay "The Burn Multiple," and it spread through Tier 1 VC IC decks within two quarters. By the end of 2023, every major firm — Sequoia, Bessemer, ICONIQ, Insight, Tiger — had standardized on it for growth-stage deal memos. There are three reasons it won, and they all matter for how you should run your business.
First, it ties directly to cash runway, which is the only thing a board genuinely cares about during a downturn. Magic number tells you about sales efficiency in isolation; burn multiple tells you how many quarters of growth you can fund before you need to raise again. That is the math the CEO actually has to manage to.
Second, it is much harder to game than CAC payback or LTV/CAC. Both of those are heavily dependent on assumptions — gross margin definitions, churn cohort selection, what counts as a "customer." Burn multiple uses two GAAP-adjacent inputs that finance can defend in any board meeting. The denominator being net new ARR (not gross new ARR) means churn shows up in the metric instantly. You cannot hide a retention problem behind a great new-logo quarter.
Third, it survives across stages. Magic number breaks down at scale because S&M efficiency curves change. LTV/CAC breaks down at early stage because cohorts are too small to be meaningful. Burn multiple works at $5M ARR and at $500M ARR with the same formula and roughly the same benchmark bands. That portability is why it has become the lingua franca of board-level efficiency conversations.
The 3 Levers to Improve It (and which works fastest)
There are exactly three ways to move burn multiple, and they map cleanly to the formula. Lever one: reduce burn. Headcount is 70%+ of operating expense at most SaaS companies, so this is fundamentally a hiring discipline conversation. Best practice in 2027 is a "VP review every backfill" policy — no auto-replacement of departed staff, every requisition justified at the leadership team level. This is the fastest lever (visible in one quarter) but politically the hardest.
Lever two: grow net new ARR faster. This is pipeline coverage plus win rate plus deal size. The challenge is that it takes 2-3 quarters to show up in the burn multiple because pipeline cycles are long. Useful but not a fast fix.
Lever three, and the most underrated: reduce churn. This one hits the denominator twice. NRR improvement raises expansion ARR (numerator of net new) and simultaneously reduces churn (subtractor of net new). A company moving NRR from 95% to 110% can cut its burn multiple by 30-40% without changing burn at all. This is why every Tier 1 board meeting in 2027 leads with NRR.
The realistic 2024-vintage Series B playbook looks like this: company is growing at 35% ARR year-over-year with a burn multiple of 2.8 (a typical number). The board sets a target of <2.0 within four quarters. The plan combines a 15% headcount reduction (lever one, immediate effect) with an NRR push from 95% to 105% (lever three, lands by quarter three). Net new ARR holds roughly flat, burn drops 20%, NRR adds another 10% to the denominator, and the math arrives at 1.7 by quarter four. That is the template repeated across dozens of growth-stage boards right now.

Why Burn Multiple Matters More in 2027 Than 2021
In the zero-interest-rate era (2020–2022), investors tolerated burn multiples of 3x–5x because growth was cheap to fund. By 2027, the capital environment has permanently shifted. Venture firms now prioritize capital efficiency as a core underwriting metric, not just a nice-to-have. A burn multiple above 2.0 can trigger down-rounds, extended bridge rounds, or forced M&A. Public market investors apply the same lens: SaaS companies trading below 6x ARR often have burn multiples above 2.5, while those above 12x ARR typically operate under 1.0x. The metric has become a universal shorthand for "can this business survive without constant infusions of cash?"
How to Calculate and Track Burn Multiple Accurately
The formula is straightforward: Net Burn ÷ Net New ARR. Net Burn = cash operating expenses minus cash revenue (typically GAAP revenue plus deferred revenue changes). Net New ARR = ending ARR minus starting ARR, adjusted for acquisitions or divestitures. A common pitfall: including one-time costs like legal fees for fundraising or M&A. Strip those out for a true operating view. Track it monthly, but evaluate quarterly to smooth noise from lumpy deals. A good rule of thumb: if your burn multiple is above 2.0 for two consecutive quarters, you need an immediate cost restructuring or a growth acceleration plan.
Practical Benchmarks for 2027 by Stage and Sector
For seed-stage companies (under $2M ARR), a burn multiple of 2.0–3.0 is common as you invest in product-market fit. Series A ($2M–$10M ARR): 1.5–2.5 is acceptable if you're proving a repeatable sales motion. Series B+ (over $10M ARR): investors expect 0.5–1.5, with best-in-class companies at 0.3–0.5. Sector matters too: vertical SaaS with long sales cycles (e.g., healthcare, manufacturing) can sustain 1.5–2.0x because contracts are stickier and expansion revenue predictable. Horizontal SaaS (e.g., collaboration tools) must be under 1.0x due to lower switching costs and higher churn risk. If you're below 0.5x, you're likely leaving growth on the table — consider investing more aggressively.
FAQ
What exactly does "burn multiple" measure? It measures how many dollars a company burns to generate each dollar of net new annual recurring revenue. The formula is net cash burned in a period divided by net new ARR added in that same period. A lower number means the company is more capital-efficient.
Is a burn multiple of 0.5 always better than 1.0? Generally yes, but context matters. A 0.5 means you're spending only $0.50 to get $1 of new ARR, which is very efficient. However, if the company is underinvesting in growth to hit that number, it might be sacrificing long-term market position. Investors typically want to see a balance between efficiency and growth rate.
How does burn multiple differ from gross margin or CAC payback? Burn multiple is a top-level cash efficiency metric that includes all operating expenses, not just sales and marketing costs. Gross margin measures unit economics on revenue, and CAC payback focuses only on customer acquisition cost. Burn multiple gives a more complete view of whether the entire business model is sustainable.
Can a company with high burn multiple still be a good investment? Yes, but only if there's a clear path to improvement. Early-stage companies often have burn multiples above 3.0 as they build product and go-to-market. The key is whether the multiple is trending down over time and whether the company has a credible plan to reach below 2.0 within 12–18 months. Investors will accept high burn temporarily if growth is exceptional.
What's a realistic burn multiple for a bootstrapped SaaS company in 2027? Bootstrapped companies typically operate with burn multiples below 1.0 because they can't afford to lose money. Many run at 0.5 or even negative (if they're profitable). This is one reason bootstrapped founders often retain more equity—they're forced to be capital-efficient from day one.
How often should founders calculate their burn multiple? Monthly is best for operational decisions, but quarterly is the standard for investor reporting. The metric can shift quickly with changes in hiring, marketing spend, or churn. Tracking it monthly helps you spot problems before they compound.
