Bessemer Efficiency Score: What It Means and How to Calculate It

The Bessemer Efficiency Score is the metric venture capitalists use to answer one question: is this company converting capital into recurring revenue efficiently, or is it burning cash to buy growth that will never pay back? The formula is simple — net new ARR divided by net burn — but the implications are not. A company that generates $1.50 in new recurring revenue for every dollar burned is in a different universe from one that generates $0.40. Both can have impressive top-line numbers. Only one has a sustainable model.

This guide explains what the Bessemer Efficiency Score measures, where it came from, how to calculate it correctly, what Bessemer Venture Partners considers Good, Better, and Best, how benchmarks shift by company stage, when the metric misleads, and how operators can move the number in the right direction. We will also compare it to burn multiple and the Rule of 40 so you know when to use each.

What Is the Bessemer Efficiency Score?

The Bessemer Efficiency Score is a capital efficiency metric developed by Bessemer Venture Partners, one of the most active investors in cloud and SaaS companies. It measures the relationship between growth and burn — specifically, how many dollars of net new annual recurring revenue a company creates for every dollar of net cash burn.

The formula is:

Net new ARR is the increase in ARR over the measurement period, accounting for new customers, expansion from existing customers, and churn or downgrades. If you started the year at $3M ARR, added $2M from new customers, expanded $800K from existing customers, and lost $300K to churn, your net new ARR is $2.5M.

Net burn is the cash lost from operations during the same period — total cash spent minus cash collected from customers. If you spent $4M and collected $2.2M in revenue, your net burn is $1.8M. Your efficiency score is $2.5M / $1.8M = 1.39x.

Net burn is not operating loss. Operating loss includes non-cash items like depreciation and stock-based compensation. Net burn is a cash figure: actual cash left the bank account. For early-stage companies, cash is what matters.

Net new ARR is also not gross bookings. If you sign $1M in new contracts but lose $400K to churn, your net new ARR is $600K. Using gross bookings instead of net new ARR flatters the number and hides retention problems.

Where the Metric Came From

Bessemer Venture Partners introduced the Efficiency Score in 2019 as part of their broader framework for evaluating cloud companies. It emerged from a simple observation: growth rate alone was no longer enough to justify investment. After the 2020–2021 zero-interest-rate period produced companies with impressive top-line numbers and catastrophic unit economics, investors needed a way to distinguish efficient growth from expensive growth.

The metric gained prominence in 2022 and 2023 as capital became more expensive and venture firms shifted from growth-at-all-costs to capital-efficiency-first investing. Bessemer's annual State of the Cloud report began featuring the Efficiency Score alongside traditional metrics like the Rule of 40, giving operators and investors a shared language for discussing burn.

In 2024, Bessemer introduced the "Rule of X" as an evolution of the Rule of 40, applying a growth multiplier that reflects the higher valuation impact of growth relative to profitability. The Efficiency Score sits alongside these frameworks as the purest measure of capital conversion: for every dollar you spend, how much recurring revenue do you create?

Research by SaaS Capital and OpenView Partners has consistently shown that efficient SaaS companies command higher valuations. In their 2024 analysis, public SaaS companies with efficiency scores above 1.5x traded at median revenue multiples approximately 2.3x higher than those with scores below 0.5x. The relationship is direct: investors pay more for companies that convert capital into revenue efficiently.

How to Calculate It: A Worked Example

The calculation is simple in theory. In practice, three decisions determine whether your number is useful or misleading: how you define net new ARR, how you define net burn, and what time period you measure.

Step 1: Calculate net new ARR

Item	Amount
New ARR from new customers	$1,800,000
Expansion ARR from existing customers	$600,000
Churned ARR (lost customers)	($200,000)
Downgraded ARR (reduced spend)	($100,000)
Net new ARR	$2,100,000

Step 2: Calculate net burn

Item	Amount
Total cash spent (operations)	$4,200,000
Cash collected from customers	$2,500,000
Net burn	$1,700,000

Step 3: Calculate the efficiency score

This company scores 1.24x — in the "Better" range by Bessemer's classification. It generates $1.24 in net new ARR for every dollar burned. At Series B, this is a solid result. At Series C, investors would expect a path to 1.5x or higher.

Common calculation traps to avoid:

• Using gross burn instead of net burn: Gross burn ignores cash collected from customers. It overstates the denominator and makes efficiency look worse than it is.
• Using a single quarter: SaaS revenue recognition and sales cycles create quarter-to-quarter volatility. Always use trailing twelve months.
• Confusing bookings with ARR: A $100K annual contract contributes $100K to ARR. A $100K multi-year contract does not contribute $300K.
• Ignoring churn and downgrades: Net new ARR must subtract both. Using gross new ARR flatters the number and hides retention problems.
• Mixing cash and accrual figures: Net burn is a cash metric. Do not use accrual-based operating expenses in the denominator.

BVP Classifications: Good, Better, Best

Bessemer Venture Partners organizes efficiency scores into three tiers. These classifications are stage-agnostic — they apply whether you are at seed or Series C — though the practical expectations shift as companies mature.

Classification	Score Range	What it means
Good	Below 0.5x	The company generates less than $0.50 in net new ARR per dollar burned. Common at seed stage. Signals heavy investment before revenue materializes.
Better	0.5x to 1.5x	The company generates $0.50 to $1.50 in net new ARR per dollar burned. Solid capital efficiency. Most Series A and B companies land here.
Best	Above 1.5x	The company generates more than $1.50 in net new ARR per dollar burned. Elite capital efficiency. Associated with premium valuations.

The classifications are not arbitrary. They reflect observed patterns across Bessemer's portfolio and the broader cloud ecosystem. A score below 0.5x means the company is investing heavily relative to its current revenue output. This is normal at seed, where product development and early sales cycles dominate. It is a warning signal at Series C, where the model should be working.

A score in the 0.5x to 1.5x range means the company is converting capital into revenue at a reasonable rate. Most venture-backed SaaS companies operate in this band during their growth phase. The key question is trajectory: is the score improving or deteriorating?

A score above 1.5x means the company is generating substantially more revenue than it burns. These are the companies that command premium valuations, raise on favorable terms, and have optionality — they can choose to invest more for growth or let profitability emerge naturally.

Benchmarks by Stage

While BVP's Good/Better/Best classifications apply across stages, the practical expectations shift as companies mature. Here are the ranges we see in practice, based on data from Bessemer's State of the Cloud report, SaaS Capital, and operator conversations.

Stage	Typical ARR	Expected Score Range	Investor Expectation
Seed	$0–$1M	0.1x–0.5x	Focus on product-market fit, not efficiency
Series A	$1M–$5M	0.3x–1.0x	Trajectory matters more than absolute score
Series B	$5M–$20M	0.5x–1.5x	Should be in "Better" range and improving
Series C	$20M–$75M	1.0x–2.0x	Should approach or exceed "Best" threshold
Growth / Pre-IPO	$75M–$200M	1.5x–3.0x	Elite efficiency expected; path to profitability clear
Public	$200M+	2.0x+ or profitable	Profitability or best-in-class efficiency

Two patterns are worth noting. First, early-stage companies often score below 0.5x because they are building product and establishing go-to-market motion before revenue arrives. A seed-stage company with a 0.2x score is not necessarily unhealthy — it may be six months away from closing its first enterprise deals. The metric becomes more meaningful as revenue scales.

Second, the most valuable public SaaS companies tend to sit in the 2.0x+ range or have crossed into profitability. Companies with scores above 1.5x at the growth stage typically have strong product-market fit, efficient sales motions, and pricing power. Companies below 0.5x at Series C face difficult fundraising conversations.

For operators, the practical takeaway is: know your stage, know your peer set, and track your trend. A Series B company moving from 0.6x to 1.2x over four quarters is a better story than a company stuck at 1.0x for two years.

Efficiency Score vs Burn Multiple

The Bessemer Efficiency Score and burn multiple measure the same relationship but invert the ratio. Understanding both is essential because different investors and operators prefer different framings.

Dimension	Bessemer Efficiency Score	Burn Multiple
Formula	Net New ARR / Net Burn	Net Burn / Net New ARR
Direction	Higher is better	Lower is better
Intuition	"How much ARR do I get per dollar burned?"	"How much burn does each dollar of ARR cost?"
1.0x threshold	Score of 1.0 = $1 ARR per $1 burn	Multiple of 1.0 = $1 burn per $1 ARR
Who uses it	Bessemer Venture Partners, growth equity	Craft Ventures, David Sacks, early-stage VCs
Best for	Board metrics, investor reporting	Operating reviews, fundraising prep

The two metrics are mathematical inverses. An efficiency score of 1.5x equals a burn multiple of 0.67x. An efficiency score of 0.5x equals a burn multiple of 2.0x. The efficiency score is generally more intuitive for operators because higher numbers signal better performance — the same direction as revenue, growth rate, and most other metrics.

Burn multiple has the advantage of familiarity in early-stage circles, where David Sacks popularized it. Some investors prefer burn multiple because it scales linearly with inefficiency: a burn multiple of 3.0x is clearly worse than 2.0x, while the corresponding efficiency scores (0.33x vs 0.5x) require more mental translation.

For most operators, we recommend tracking the Bessemer Efficiency Score as the primary metric and burn multiple as a secondary check. Use the efficiency score in board decks and investor updates. Use burn multiple in operating reviews if your team is already familiar with it.

Efficiency Score vs Rule of 40

The Rule of 40 and the Bessemer Efficiency Score are the two most cited efficiency metrics in SaaS. They measure different things and serve different purposes.

Dimension	Bessemer Efficiency Score	Rule of 40
What it measures	Capital efficiency — ARR per dollar burned	Growth-profitability balance
Formula	Net New ARR / Net Burn	Revenue growth % + Profit margin %
Best for	Pre-profitability and growth-stage companies	Companies at or near profitability
Target	Above 1.0x at Series B	40% or higher
Key weakness	Ignores absolute growth rate	Ignores capital efficiency
When to use	Fundraising, operating reviews, capital planning	Board metrics, public comparables

A company can score well on one metric and poorly on the other. A fast-growing company burning heavily might have a 0.6x efficiency score but a 55% Rule of 40 score (60% growth, negative 5% margin). The Rule of 40 says the overall profile is strong. The efficiency score says the growth is expensive.

Conversely, a company with 15% growth and 30% margins scores 45% on Rule of 40 — excellent. But if its efficiency score is 0.3x, it is spending inefficiently to achieve that modest growth. The two metrics together tell a fuller story than either alone.

For most Series A and B companies, the Bessemer Efficiency Score is the more actionable metric. It isolates the efficiency of the growth engine. The Rule of 40 becomes more relevant as companies approach scale and profitability becomes a realistic target.

When the Efficiency Score Misleads

The Bessemer Efficiency Score is a useful filter. It is not a complete picture. Here are the five situations where it misleads most often.

1. It ignores absolute growth rate

A company with $100K in net new ARR and $50K in net burn has an efficiency score of 2.0x — elite. But $100K in net new ARR is not a meaningful business. The efficiency score rewards small scale. A company with $5M in net new ARR and $3M in net burn scores 1.67x — also excellent — but the absolute numbers tell a different story about market traction. Always evaluate the efficiency score alongside absolute ARR growth.

2. It can be gamed by underinvestment

A company that stops hiring sales reps, cuts marketing spend, and freezes R&D will see its efficiency score improve dramatically. It is also destroying its growth engine. The metric looks good. The business is shrinking its future. This is the most common way founders game the number before a fundraise — and the most easily detected by investors who look at growth rate alongside efficiency.

3. It ignores one-time revenue boosts

A large professional services contract, a one-time implementation fee, or an early renewal pulled forward can inflate net new ARR without reflecting true recurring growth. The efficiency score rises. The underlying business is unchanged. Distinguishing recurring from non-recurring revenue is essential.

4. It ignores gross margin

A company with 50% gross margins and a 1.5x efficiency score is not more efficient than a company with 80% gross margins and a 1.2x score. The first company spends half its revenue on service delivery. The second company spends 20%. The efficiency score does not capture gross margin. It must be evaluated alongside it.

5. It ignores revenue quality

Not all ARR is equal. A company with 90% contracted annual recurring revenue, low churn, and strong expansion revenue is fundamentally different from a company with the same net new ARR but 40% usage-based revenue, high churn, and no expansion. The efficiency score treats both as identical. Net revenue retention and gross revenue retention are essential companions.

"The efficiency score tells you whether your growth is expensive. It does not tell you whether your growth is good."

5 Ways to Improve Your Efficiency Score

Improving the Bessemer Efficiency Score means either increasing net new ARR (the numerator) or decreasing net burn (the denominator) — or both. Here are five levers that work.

1. Reduce CAC payback period

The fastest way to improve efficiency is to acquire customers more efficiently. This means reducing the sales cycle, improving conversion rates, or lowering acquisition costs. Tactics include: refining ideal customer profile to focus on segments that close fastest, improving demo-to-close rate through better qualification, and shifting spend from high-CAC channels to organic or product-led growth.

Companies with product-led growth motions often achieve CAC payback periods under 12 months. Sales-led companies targeting enterprise buyers may need 18–24 months. Both can be efficient if the lifetime value justifies the payback period.

2. Improve net revenue retention

Net revenue retention above 110% means your existing customer base grows without new sales spend. Every point of NRR improvement drops your effective burn because the same burn produces more ARR. Tactics include: implementing usage-based pricing that grows with customer value, building expansion revenue through add-on products or seats, and running proactive health scoring to catch churn risk before it becomes cancellation.

3. Shorten the sales cycle

A 12-month sales cycle means you burn cash for a full year before seeing ARR. A 6-month cycle means the same ARR arrives twice as fast, effectively improving your efficiency score for new deals. Tactics include: simplifying pricing to reduce negotiation time, offering self-service trials for smaller deals, and using mutual action plans to keep deals on timeline.

4. Cut non-revenue spend

Not all burn is equal. Engineering spend on core product features drives future ARR. Engineering spend on internal tools that could be bought off-the-shelf does not. Office space in a premium location does not drive ARR. A bloated executive team does not drive ARR. The exercise is simple: categorize every dollar of burn by its direct or indirect contribution to net new ARR. Cut the categories with the weakest link.

5. Measure monthly, not quarterly

The efficiency score is typically calculated quarterly for board reporting. Operators who want to improve it should track a rolling 12-month figure updated monthly. Monthly tracking catches efficiency drift early — before it becomes a board-level problem. Set a target efficiency score for the quarter. Track actual vs. target monthly. Investigate variances immediately.

In our experience, companies that focus on both levers simultaneously can move their efficiency score 0.3–0.5x in 12 months. Companies that focus on only one lever often see the other deteriorate — growth investments depress the score in the short term, or burn cuts stall growth.

How Fairview Helps Track the Bessemer Efficiency Score

The Bessemer Efficiency Score is a simple formula. Tracking it accurately in practice is not simple. The numerator requires clean ARR data from your CRM. The denominator requires clean cash data from your accounting system. Most operators calculate it manually once per quarter — which means they discover problems too late to fix them.

Fairview connects to your CRM (HubSpot, Salesforce, Pipedrive) and finance tools (Stripe, QuickBooks, Xero) through a Data Connection Layer that normalizes data across sources. The Operating Dashboard surfaces ARR, net new ARR, and burn in one view — updated daily, not quarterly.

Margin Intelligence pulls cost data from connected accounting tools and revenue data from payment processors. It calculates contribution margin by channel, campaign, and product line — the inputs you need to understand which parts of your business drive efficient ARR growth and which parts drag the number down. If your enterprise segment has a 1.8x efficiency score and your SMB segment has a 0.4x score, the aggregate number hides the problem. Fairview shows the split.

The Forecast Confidence Engine projects future ARR based on pipeline stage, historical close rates, and deal velocity. This lets you estimate your efficiency score for the next quarter before the quarter ends — not after. The Weekly Operating Report summarizes ARR growth, burn, and efficiency trends every Monday morning, so operators arrive at their review already briefed.

Fairview does not replace your financial model or your CFO. It replaces the manual work of assembling the data that feeds both — and surfaces the anomalies that tell you whether the story behind the score is strengthening or weakening.

Key Takeaways

• The Bessemer Efficiency Score measures capital efficiency: net new ARR divided by net burn. Higher is better. It answers what growth rate cannot: whether your growth is expensive or efficient.
• BVP classifications: Good is below 0.5x, Better is 0.5x to 1.5x, Best is above 1.5x. These apply across stages, but practical expectations rise as companies mature.
• The efficiency score is the inverse of burn multiple. A score of 1.5x equals a burn multiple of 0.67x. Use the efficiency score for board reporting and investor updates. It is more intuitive because higher means better.
• The efficiency score can mask underinvestment, one-time revenue, or low gross margins. Always evaluate it alongside growth rate, gross margin, and net revenue retention.
• The five levers to improve: reduce CAC payback, improve NRR, shorten sales cycles, cut non-revenue spend, and measure monthly.
• The efficiency score and Rule of 40 complement each other. The efficiency score is more actionable for pre-profitability companies. The Rule of 40 becomes more relevant at scale.

How do you calculate the Bessemer Efficiency Score?

Calculate net new ARR by adding new ARR and expansion ARR, then subtracting churned and downgraded ARR. Calculate net burn by subtracting cash collected from customers from total cash spent on operations. Then divide net new ARR by net burn. For example, a company with $1.2M in net new ARR and $800K in net burn has an efficiency score of 1.5x.

What is a good Bessemer Efficiency Score by company stage?

Bessemer Venture Partners classifies scores into three tiers: Good is below 0.5x, Better is 0.5x to 1.5x, and Best is above 1.5x. In practice, seed-stage companies often score below 0.5x as they invest heavily before revenue materializes. Series A companies should target 0.5x to 1.0x. Series B and C companies should aim for 1.0x to 1.5x. Public SaaS companies with scores above 1.5x typically command premium valuations.

How is the Bessemer Efficiency Score different from burn multiple?

The Bessemer Efficiency Score and burn multiple measure the same relationship but invert the ratio. Efficiency Score equals net new ARR divided by net burn — higher is better. Burn multiple equals net burn divided by net new ARR — lower is better. An efficiency score of 1.5x is equivalent to a burn multiple of 0.67x. The efficiency score is more intuitive for most operators because a higher number signals better performance.

Can a company have a high Bessemer Efficiency Score and still be unhealthy?

Yes. A high efficiency score can mask underinvestment in growth, one-time revenue boosts, or low gross margins. A company that stops hiring sales reps and cuts marketing will see its efficiency score improve dramatically while destroying its growth engine. Similarly, a large one-time professional services contract can inflate net new ARR without reflecting true recurring growth. The efficiency score should always be evaluated alongside growth rate, gross margin, and net revenue retention.
