Burn Multiple

What is burn multiple?

Burn multiple (coined by David Sacks of Craft Ventures) is the ratio of cash consumed to net new ARR generated. It answers one question: how efficiently does the company convert cash into recurring revenue? A burn multiple of 1.0x means $1 burned for every $1 of new ARR. A burn multiple of 3.0x means $3 burned for the same $1.

Burn rate alone is misleading. A company burning $500K per month is in trouble if it's adding $100K in net new ARR (burn multiple: 5x). The same burn rate is efficient if it's adding $600K in net new ARR (burn multiple: 0.83x). Burn multiple connects the cash going out to the revenue it produces.

For venture-backed SaaS companies, burn multiple has largely replaced burn rate as the primary efficiency metric. Investors use it to evaluate whether a company's growth is sustainable or whether it's buying revenue at an unaffordable rate.

Burn multiple is not the same as CAC. CAC measures the cost per customer. Burn multiple measures the total cash cost per dollar of new ARR — including R&D, G&A, and all overhead, not just sales and marketing. It's a company-level efficiency metric, not a go-to-market metric.

Why burn multiple matters for operators

Burn multiple tells operators whether the company is getting more or less efficient over time. A company whose burn multiple is declining from 2.5x to 1.5x is improving — each dollar of burn produces more ARR. A company whose burn multiple is rising from 1.5x to 2.5x is losing efficiency — a signal that growth is becoming more expensive.

The practical consequence is fundraising math. A company with $3M in net new ARR per year and a 2x burn multiple is burning $6M annually. At that rate, $12M in the bank lasts 2 years. If burn multiple rises to 3x, the same growth costs $9M and the runway drops to 16 months. Operators who track burn multiple quarterly can adjust spending before the runway becomes critical.

Burn multiple also reveals when to shift from growth-at-all-costs to efficient growth. When burn multiple exceeds 2x for two consecutive quarters, the company is spending too much for each incremental dollar. The response: either find more efficient growth channels or reduce non-growth spending.

Burn multiple formula

Burn Multiple = Net Cash Burn / Net New ARR

Example:
- Net cash burn in Q1: $1,800,000
- Net new ARR added in Q1: $1,200,000
  (New ARR: $1,500,000 - Churned ARR: $180,000 - Contraction: $120,000)

Burn Multiple = $1,800,000 / $1,200,000 = 1.5x

The company burned $1.50 for every $1 of net new recurring revenue.

What each component means:

• Net cash burn: Total cash out minus total cash in for the period (from the cash flow statement). This includes all expenses — not just sales and marketing.
• Net new ARR: New subscription revenue added minus churned and contracted revenue. Uses net new, not gross new, to reflect the true ARR gain.

Why "net" on both sides matters:

Gross burn / gross new ARR = 2.0x (looks acceptable)
Net burn / net new ARR = 3.2x (actually alarming)

The difference: churn erodes new ARR, and some cash came from
non-recurring sources. The net-net version is the honest number.

Common mistakes with burn multiple

1. Using gross new ARR instead of net new ARR

If churn is 15% and expansion is 5%, gross new ARR and net new ARR diverge significantly. A company adding $2M in gross new ARR but losing $500K to churn has $1.5M net new ARR. Using gross new ARR understates the burn multiple by 33%. Always use net.

2. Measuring burn multiple monthly

Monthly burn multiple is volatile. One large deal closing moves the number dramatically. Measure quarterly or on a trailing-12-month basis. The quarterly view catches trends without being distorted by monthly revenue timing.

3. Not separating growth spend from infrastructure spend

A company with 2.5x burn multiple might be spending heavily on R&D infrastructure that will pay off in 6 months. The burn multiple doesn't distinguish between growth-related spend and infrastructure investment. When burn multiple is high, decompose the spend to understand what's driving it.

4. Comparing burn multiples across different company stages

A seed-stage company at 2x burn multiple is normal — it's investing ahead of product-market fit. A Series C company at 2x has a problem — it should have found efficient growth channels by now. Stage context changes the interpretation completely.

How Fairview tracks burn multiple automatically

Fairview's Margin Intelligence connects to your accounting platform (QuickBooks, Xero) to calculate net cash burn and pairs it with ARR data from your CRM and payment processor. Burn multiple is calculated quarterly and displayed alongside ARR growth rate and the Rule of 40 score.

The Operating Dashboard trends burn multiple over time with a breakdown of what's driving changes — S&M spend, R&D investment, G&A overhead, and churn rate. When burn multiple rises above the company's target threshold, the Next-Best Action Engine flags it: "Burn multiple increased from 1.4x to 2.1x. S&M spend grew 28% while net new ARR grew only 8%. Review channel efficiency."

Burn multiple vs burn rate

Burn rate tells you how long the money lasts. Burn multiple tells you what the money is producing. A $500K monthly burn rate is fine at 0.8x burn multiple (efficient growth). It's terrible at 4x burn multiple (spending $4 for every $1 of new revenue).

FAQ

What is burn multiple in simple terms?

Burn multiple tells you how much cash the company burns for every dollar of new recurring revenue it adds. If you burned $2M last quarter and added $1M in net new ARR, your burn multiple is 2x. Lower is better — below 1.5x means efficient growth, above 2x signals the growth engine needs work.

What is a good burn multiple for SaaS?

Below 1x is excellent. Between 1x and 1.5x is good. Between 1.5x and 2x is acceptable for early-stage companies still finding efficient channels. Above 2x for more than 2 consecutive quarters signals a structural efficiency problem. The benchmark varies by stage — seed-stage companies get more tolerance.

How do you calculate burn multiple?

Divide net cash burn by net new ARR. Net burn is total cash out minus total cash in from the cash flow statement. Net new ARR is new subscription revenue minus churned and contracted revenue. Example: $1.5M net burn / $900K net new ARR = 1.67x burn multiple.

What is the difference between burn multiple and CAC?

CAC measures sales and marketing cost per new customer. Burn multiple measures total company cash burn per dollar of new ARR — including R&D, G&A, and all overhead. A company can have efficient CAC but high burn multiple if non-growth expenses are bloated.

How often should you track burn multiple?

Quarterly is the standard cadence. Monthly is too volatile — one large deal or late payment can swing the number dramatically. Quarterly smooths timing effects while still catching deteriorating efficiency early. Compare trailing 4-quarter averages for the most stable signal.

Can burn multiple be negative?

Yes — in a good way. Negative burn multiple means the company is cash-flow positive while still adding ARR. The numerator (net burn) is negative because cash in exceeds cash out. This typically happens at scale when operating leverage kicks in. It's the sign of a self-funding growth engine.
