Burn Multiple: Formula & SaaS Benchmarks

What Is Burn Multiple?

Burn multiple is a capital efficiency metric that divides net burn by net new ARR to show how many dollars a company consumes to add one dollar of annual recurring revenue. Introduced by investor David Sacks in 2020, it answers a blunt question: what is this growth actually costing?

How Burn Multiple Works

The metric works because both inputs are net. Net burn is total cash out minus total cash in over the period, not operating expenses and not EBITDA. It captures payroll, marketing, capital expenditure, working capital swings, and the timing of collections. Net new ARR is ending ARR minus beginning ARR, so churn and contraction reduce it just as expansion increases it.

That construction is deliberate. A company can post impressive gross new bookings while losing nearly as much to churn, and the burn multiple exposes it immediately. Two companies adding $4,000,000 of gross new ARR look identical until one loses $3,000,000 to churn, at which point their burn multiples differ by a factor of four on the same spend.

Measure it quarterly at minimum, and on a trailing twelve month basis for anything an investor sees, since one quarter can be distorted by a single annual prepayment.

How to Calculate Burn Multiple

Formula: Net Burn / Net New ARR

A company enters the quarter at $12,000,000 of ARR and exits at $14,000,000, adding $2,000,000 of net new ARR. It consumed $3,000,000 of cash over the same quarter. The burn multiple is $3,000,000 divided by $2,000,000, or 1.5. Every dollar of new recurring revenue cost a dollar fifty of cash.

The commonly cited benchmark bands are straightforward. Under 1 is great, 1 to 1.5 is good, 1.5 to 2 is okay, 2 to 3 is suspect, and above 3 is bad. A company burning more than three dollars for each dollar of net new ARR is usually either buying growth at unsustainable cost or has a retention problem masquerading as a growth problem. Read the bands with stage in mind: a seed stage company with a small ARR base can post a wild number for a quarter and be fine, while a company past $20,000,000 of ARR sitting above 2 has a structural issue.

Burn Multiple in Plain English

Burn multiple is the price tag on growth. Growth rate tells you how fast you are moving. Burn multiple tells you what the fuel cost, and whether you could keep moving at that speed without raising again.

Why Burn Multiple Beats Growth Rate Alone

Growth rate is easy to buy. Discount aggressively, hire ahead of demand, spend into paid channels with weak payback, and the growth number improves for two or three quarters. None of that shows up in a growth rate. All of it shows up in a burn multiple.

The metric is also harder to dress up than most alternatives. Adjusted EBITDA can be adjusted. Contribution margin depends on what you put above the line. Net burn is what left the bank account, and net new ARR is what the customer base actually did.

How Burn Multiple Relates to Rule of 40 and Runway

Rule of 40 measures growth rate plus profit margin and asks whether the combination clears a threshold. Burn multiple measures the exchange rate between cash and recurring revenue. A company can pass Rule of 40 on the strength of growth alone while running a burn multiple above 2, which is a signal that the growth is being financed rather than earned.

Runway connects the two. Runway is cash divided by net burn, so it tells you how long you can keep going. Burn multiple tells you what you get for that time. A company with 24 months of runway and a burn multiple of 3 has time and no efficiency, which is usually worse than 14 months of runway and a burn multiple of 0.9.

How Teams Accidentally Game Burn Multiple

The easiest way to improve the metric without improving the business is to move cash across a period boundary. Push a large collection into the current quarter, defer vendor payments to the next one, and net burn falls for a quarter. Nothing changed. Similarly, counting gross new ARR instead of net new ARR flatters the denominator and defeats the purpose of the metric.

The honest version is to compute it on a trailing twelve month basis, reconcile net burn to the cash flow statement, and show the ARR bridge that produced net new ARR: new, expansion, contraction, and churn stated separately.

Burn Multiple and the Closing Motion

Burn multiple has a numerator most teams treat as fixed. Net burn is not only a spending question, it is a collections question: a company that signs a $500,000 contract and receives the cash over 12 months burns more, at the same ARR, than one that receives it at signature. That is the Collect stage showing up directly in a capital efficiency metric. With Ratio Trade, the buyer pays monthly or quarterly while the seller collects the full contract value upfront, which lowers net burn without changing headcount, price, or growth. Ratio Boost does the same for existing recurring contracts without dilution or warrants. Neither fixes weak unit economics, but both stop bad cash timing from being reported as poor efficiency.

Common Questions About Burn Multiple

What is a good burn multiple?

Below 1 is excellent and rare, 1 to 1.5 is good, and 1.5 to 2 is acceptable for a company in a heavy investment phase. Above 2 invites questions, and above 3 usually indicates a retention or pricing problem rather than a spending problem.

Should burn multiple use gross or net new ARR?

Net new ARR, always. Using gross new ARR hides churn and contraction, which is exactly what the metric exists to reveal. If churn is material, publish the ARR bridge alongside the multiple so the number can be checked.

Can burn multiple be negative?

Yes, and it means two different things. A profitable company generating cash while growing produces a negative multiple, which is excellent. A burning company whose ARR shrank also produces a negative number, which is meaningless, so report ARR contraction directly instead.
