Your board is asking about capital efficiency. Your investors want to know your burn multiple. You have 18 months of runway left. And you have no idea what number they are expecting to see.

David Sacks at Craft Ventures introduced the burn multiple in 2020 as the cleanest way to measure capital efficiency. In 2020 through 2022, his thresholds were generous: under 1 was amazing, 1 to 2 was acceptable, 2 to 3 was concerning, and over 3 was broken. Capital was cheap. Growth was the only question that mattered.

That world is gone.

In 2026, investors have tightened the bar by roughly 25 to 30 percent. The new acceptable looks a lot like what used to be great. If you are pitching a Series A this year on 2022 benchmarks, you will go through round after round and not understand why.

This guide covers the exact burn multiple formula, the 2026 benchmarks investors are actually using, the three calculation mistakes that inflate your number, and the five operational levers that move it most in 90 days.

What Is Burn Multiple and Why VCs Obsess Over It in 2026

The best capital efficiency metric for B2B SaaS companies in 2026 is the burn multiple because it captures total cash efficiency in a single number that is difficult to game and correlates directly with valuation.

The burn multiple is a capital efficiency metric that tells you how much cash your company burns to generate each dollar of net new annual recurring revenue.

Here is the simple version: If you burned $2 million in a quarter and added $1 million in net new ARR, your burn multiple is 2.0. You spent $2 to generate $1 of new recurring revenue.

David Sacks, co-founder and general partner of Craft Ventures, coined the burn multiple in an April 2020 essay. His goal was a single number that put the focus squarely on burn relative to growth.

Why investors reach for it in 2026: Sacks argues the burn multiple is a proxy for almost everything else in the business, because any serious problem eventually shows up in it.

• A gross margin problem raises burn as you scale
• A sales efficiency problem raises burn relative to new ARR
• A churn problem nets against the denominator, so the multiple climbs
• A stalling growth problem tempts you to discount and spend more on promotions, which lands in a higher multiple

One number. Hard to game. That is why investors reach for it.

Bessemer Venture Partners’ 2026 Cloud Atlas identifies burn multiple as the single highest-correlation valuation predictor post-2024. In 2026’s concentrated venture capital market, investors screen for burn multiple under 1.5 and Rule of 40 above 40 before a first meeting. Figures based on Bessemer 2026 Cloud Atlas. Individual results vary.

The Burn Multiple Formula: How to Calculate It Correctly

The correct formula for calculating burn multiple is net burn divided by net new ARR, with both inputs measured over the same period.

The burn multiple formula is simple:

Burn Multiple = Net Burn ÷ Net New ARR

Both inputs must cover the same measurement period — monthly, quarterly, or annually.

Net Burn (The Numerator)

Net Burn is the net cash consumed by the business during the measurement period. It is a cash-flow measure, not the same thing as operating loss or EBITDA.

Net Burn = Cash Revenue – Cash Operating Expenses (excluding financing activities like equity raises, debt proceeds, and debt repayments)

Capitalized software development, capital expenditures, and changes in working capital can cause cash burn to differ materially from the loss reported on the income statement.

Net New ARR (The Denominator)

Net New ARR is the increase in ARR during the same measurement period.

Net New ARR = Ending ARR – Beginning ARR

Expressed through an ARR waterfall, that generally equals:

Net New ARR = New ARR + Expansion ARR – Contraction ARR – Churn ARR

Step-by-Step Calculation with Real SaaS Examples

Example 1: The Efficient SaaS Company

The numbers:

• Quarterly net cash burn: $200,000
• Quarterly net new ARR: $250,000

The calculation:

Burn Multiple = $200,000 ÷ $250,000 = 0.8x

What this means: You burned $0.80 for every $1 of net new ARR generated. This is excellent — top quartile performance.

Example 2: The Average SaaS Company

The numbers:

• Quarterly net cash burn: $500,000
• Quarterly net new ARR: $250,000

The calculation:

Burn Multiple = $500,000 ÷ $250,000 = 2.0x

What this means: You burned $2 for every $1 of net new ARR generated. This is acceptable for seed but concerning for Series A.

Example 3: The Inefficient SaaS Company

The numbers:

• Quarterly net cash burn: $1,250,000
• Quarterly net new ARR: $250,000

The calculation:

Burn Multiple = $1,250,000 ÷ $250,000 = 5.0x

What this means: You burned $5 for every $1 of net new ARR generated. David Sacks calls this terrible — you should probably cut costs immediately.

2026 Burn Multiple Benchmarks by Stage and ARR

The best way to benchmark your burn multiple in 2026 is against stage-specific and ARR-specific thresholds because investors tighten expectations as the company matures.

Here are the actual 2026 thresholds investors are using. The thresholds tighten as the company matures.

The Interpretation Scale (David Sacks, Craft Ventures)

The 3 Mistakes That Inflate Your Burn Multiple by 30-50%

The most common mistake founders make when calculating burn multiple is using gross new ARR instead of net new ARR, which inflates the number by 30 to 50 percent.

Most founders quote a burn multiple that is 30 to 50 percent lower than the one a Series A investor will compute. The arithmetic is identical. The inputs are not.

Mistake 1: Gross New ARR vs Net New ARR

This one alone explains most of the discrepancy.

• Gross new ARR = ARR added from new customers + expansion from existing customers
• Net new ARR = Gross new ARR minus ARR lost from churn and downgrades

Founders quote gross because it is bigger. Investors compute net because that is what actually matters.

Example: You added $1M in new ARR but lost $300K to churn. Your gross new ARR is $1M. Your net new ARR is $700K. If your burn is $1.4M, your gross burn multiple is 1.4x — but your net burn multiple is 2.0x. That is the difference between a term sheet and a polite pass.

Mistake 2: Using Operating Loss Instead of Cash Burn

Net Burn is a cash-flow measure, not the same thing as operating loss or EBITDA.

Capitalized software development, capital expenditures, and changes in working capital can cause cash burn to differ materially from the loss reported on the income statement.

Companies often exclude unusual acquisitions, investment activity, or treasury movements that do not reflect the underlying cost of operating and growing the business.

Fix: Calculate net burn from the change in cash after removing financing activity such as equity raises, debt proceeds, and debt repayments.

Mistake 3: Mismatched Measurement Periods

The numerator and denominator must cover the same measurement period — monthly, quarterly, or annually.

A common error: calculating burn over 12 months but ARR growth over a different period. If the periods do not match, the resulting burn multiple will not provide a meaningful measure of capital efficiency.

Recommendation: Calculate it on a rolling three-month basis. One month is too short; 12 months can hide recent trends.

How to Improve Your Burn Multiple in 90 Days

The fastest way to improve your burn multiple in 90 days is to fix churn and increase sales efficiency because both directly increase the denominator without increasing burn.

The burn multiple is not a fixed number. Here are the five operational levers that move it most.

Lever 1: Fix Your Churn (The Denominator)

Churn reduces your net new ARR — which increases your burn multiple. A churn problem nets against the denominator, so the multiple climbs.

Action: Identify why customers are leaving and fix it. Even a 2 percent reduction in churn can significantly improve your burn multiple.

Lever 2: Increase Sales Efficiency (The Denominator)

A sales efficiency problem raises burn relative to new ARR.

Action: Optimize your sales process. Shorten sales cycles. Increase win rates. Improve lead quality. Every improvement flows directly to your burn multiple.

Lever 3: Reduce Cash Burn (The Numerator)

This is the most obvious lever. Lower your net burn while maintaining growth.

Action: Cut non-essential spending. Delay non-critical hires. Renegotiate vendor contracts. Every dollar saved reduces your burn multiple.

Lever 4: Improve Gross Margin (The Numerator)

A gross margin problem raises burn as you scale.

Action: Optimize your cost of goods sold. Automate manual processes. Negotiate better rates with suppliers. Higher margins equal lower burn, which equals a better burn multiple.

Lever 5: Focus on Expansion Revenue (The Denominator)

Expansion from existing customers is the most efficient growth engine.

Action: Build upsell and cross-sell motions. Improve customer success. Increase net revenue retention. Expansion revenue adds to net new ARR without increasing burn.

Burn Multiple vs Magic Number vs Rule of 40

The burn multiple has replaced the Magic Number as the primary efficient-growth metric in 2026 because it captures total cash efficiency rather than just sales and marketing efficiency.

Burn multiple has largely replaced Magic Number as the primary efficient-growth metric in 2024 through 2026 SaaS investor circles.

Why Burn Multiple won:

• It captures total cash efficiency, not just sales and marketing efficiency
• It works at any stage from pre-revenue to profitable
• It is expressed in dollars rather than ratios, so the math is intuitive

How they compare:

• Magic Number: Measures sales and marketing efficiency only (new ARR ÷ sales and marketing spend). Does not account for other costs.
• Rule of 40: Measures growth plus profitability. Does not directly measure capital efficiency.
• Burn Multiple: Measures total cash efficiency. Captures everything.

Bessemer’s 2026 Cloud Atlas identifies burn multiple as the single highest-correlation valuation predictor post-2024. In 2026’s concentrated venture capital market, investors screen for burn multiple under 1.5 and Rule of 40 above 40 before a first meeting. Figures based on Bessemer 2026 Cloud Atlas.

Frequently Asked Questions

What is a good burn multiple for a SaaS company in 2026?
Under 1.5x is generally considered fundable for Series A, with the top quartile running between 1.0x and 1.2x. Under 1.0x is elite. Above 2.0x invites serious investor scrutiny.

What is the burn multiple formula?
Burn Multiple = Net Burn ÷ Net New ARR. Both inputs must cover the same measurement period — monthly, quarterly, or annually.

How do you calculate net burn?
Net Burn = Cash Revenue – Cash Operating Expenses (excluding financing activities like equity raises, debt proceeds, and debt repayments).

What is net new ARR?
Net New ARR = Ending ARR – Beginning ARR = New ARR + Expansion ARR – Contraction ARR – Churn ARR.

What burn multiple do VCs expect for Series A in 2026?
Under 1.5x is expected. Under 1.0x is amazing. Above 2.0x will not raise. A burn multiple of 1.4 gets you a term sheet. 1.5 gets you let us circle back next quarter.

How can I improve my burn multiple quickly?
The five operational levers are: fix churn, increase sales efficiency, reduce cash burn, improve gross margin, and focus on expansion revenue. Most impact comes from fixing churn and increasing sales efficiency.

What is the difference between gross and net new ARR?
Gross new ARR equals ARR added from new customers plus expansion. Net new ARR equals gross new ARR minus ARR lost from churn and downgrades. Founders quote gross because it is bigger. Investors compute net because that is what actually matters. Using gross instead of net inflates your burn multiple by 30 to 50 percent.

Is burn multiple more important than Rule of 40?
In 2026’s funding environment, both matter. Investors screen for burn multiple under 1.5x and Rule of 40 above 40 before a first meeting. Bessemer’s 2026 Cloud Atlas identifies burn multiple as the single highest-correlation valuation predictor.
