Key Takeaways
- The median monthly burn rate for a seed-stage startup is $50,000 to $150,000, rising to $500,000 to $2 million per month at Series B, per PitchBook and SaaS Capital data
- A burn multiple below 1.5x is the current benchmark for capital efficiency at Series A and B, per Bessemer Venture Partners State of the Cloud 2025
- 29% of startups that fail cite running out of cash as the primary cause, making burn rate management the single highest-leverage survival lever, per CB Insights
- Y Combinator recommends 18 months of runway as the default target before and after each funding round; most venture investors expect to see at least 12 to 15 months at any given time
- SaaS startups burning more than 50% of ARR annually as net burn are considered inefficient by Series B investors; the top quartile burns under 30% of ARR
Burn rate is the amount of money a startup spends each month in excess of what it brings in. It determines how long the company can survive before needing additional capital, and it is one of the first numbers investors ask for at every stage.
In 2026, the benchmarks are tighter than they were three years ago. After a period of cheap capital and loose efficiency standards from 2019 to 2021, the venture market correction that began in 2022 reset expectations across the board. Startups are now judged not just on growth rate but on how much capital that growth costs.
What is startup burn rate?
Startup burn rate is the net cash a company consumes per month. Two versions of the metric are in common use.
Gross burn rate is total monthly cash outflows, including salaries, rent, software, contractors, marketing, and every other expense regardless of revenue.
Net burn rate is gross burn minus revenue. If a startup spends $200,000 per month and brings in $60,000 in revenue, net burn is $140,000.
Net burn is the number investors care about because it tells them how much cash the company actually consumes to operate. Gross burn matters for cost structure analysis but is less useful for calculating runway.
Runway is months of capital remaining at the current net burn rate:
Runway = Cash on hand / Monthly net burn
A startup with $1.8 million in the bank burning $100,000 per month net has 18 months of runway.
Why burn rate benchmarks matter
Running out of cash is the most common cause of startup failure. CB Insights analyzed over 1,100 startup post-mortems across the 2023 to 2025 period and found 29% of failing startups cited running out of cash as the primary cause. No other single factor came close.
The second reason benchmarks matter is investor signaling. Burn rate relative to growth tells investors whether a business is capital-efficient or burning through money without compounding returns. In the 2019 to 2021 environment, investors tolerated high burn in exchange for growth. By 2024 and 2025, the standard changed. Bessemer Venture Partners, Andreessen Horowitz, and Sequoia all published frameworks requiring founders to demonstrate capital efficiency before Series B and beyond.
A burn rate in line with stage benchmarks does not guarantee success. But a burn rate significantly above those benchmarks is one of the clearest signals that a company will struggle to raise its next round.
Startup burn rate benchmarks by stage (2026)
Pre-seed
Pre-seed startups are typically pre-product or in early product development. Many are still founder-only operations.
| Metric | Benchmark |
|---|---|
| Typical team size | 1 to 3 people |
| Monthly gross burn | $15,000 to $50,000 |
| Monthly net burn | $10,000 to $45,000 (most are pre-revenue) |
| Typical capital raised | $250,000 to $1.5 million |
| Target runway | 12 to 18 months |
Sources: PitchBook Venture Monitor Q1 2026; First Round Capital portfolio benchmarks; AngelList State of Pre-Seed 2025
Pre-seed burn at the high end is typically a two to three person team with office space, early infrastructure costs, and some paid marketing or user research. Pre-seed startups spending more than $70,000 per month are often over-investing in team before achieving product-market fit, a pattern that accelerates failure rather than preventing it.
Seed
Seed rounds now typically raise $1 million to $4 million, and teams have grown to 4 to 10 people. Product is live or in closed beta.
| Metric | Benchmark |
|---|---|
| Typical team size | 4 to 10 people |
| Monthly gross burn | $50,000 to $200,000 |
| Monthly net burn | $40,000 to $150,000 |
| Typical capital raised | $1 million to $4 million |
| Target runway after raise | 18 to 24 months |
| Top-quartile net burn (efficiency) | Under $80,000/month |
Sources: PitchBook Venture Monitor Q1 2026; Y Combinator guidance 2025; SaaS Capital 2025 Private SaaS Company Survey
The top quartile at seed is spending under $80,000 per month net. The median is $100,000 to $120,000. Startups at the high end of the range, $150,000 or more monthly, are typically either engineering-heavy (competitive technical markets) or have made early GTM hires ahead of traction.
SaaS Capital's 2025 survey of over 1,500 private SaaS companies found seed-stage SaaS startups with ARR under $500,000 have median gross burn of $120,000 per month. That figure includes founder salaries, which many early-stage benchmarks exclude.
Series A
Series A rounds in 2025 and 2026 average $8 million to $18 million. Teams have reached 15 to 40 people and initial product-market fit has been established.
| Metric | Benchmark |
|---|---|
| Typical team size | 15 to 40 people |
| Monthly gross burn | $200,000 to $600,000 |
| Monthly net burn | $150,000 to $400,000 |
| Typical ARR at raise | $1 million to $4 million |
| Target runway at raise | 18 to 24 months |
| Top-quartile burn multiple | Under 1.5x |
| Median burn multiple | 2.0 to 2.5x |
Sources: PitchBook Q1 2026 Venture Monitor; Bessemer Venture Partners State of the Cloud 2025; KeyBanc Capital Markets SaaS Survey 2025
Burn multiple at Series A is the ratio of net burn to net new ARR in a given period. A company adding $100,000 ARR per month while burning $200,000 net has a burn multiple of 2.0x. Bessemer's 2025 State of the Cloud defines the efficiency benchmarks as follows:
| Burn multiple | Assessment |
|---|---|
| Under 1.0x | Outstanding |
| 1.0x to 1.5x | Good |
| 1.5x to 2.0x | Acceptable |
| 2.0x to 3.0x | High; needs improvement |
| Over 3.0x | Unsustainable |
Source: Bessemer Venture Partners State of the Cloud 2025
Series A investors increasingly use burn multiple as a primary screen. Companies with burn multiples above 2.5x at the time of Series B fundraising will face significantly harder diligence conversations and higher dilution to close the round.
Series B
Series B rounds average $25 million to $50 million. Companies are scaling a proven model, often across multiple geographies or segments.
| Metric | Benchmark |
|---|---|
| Typical team size | 50 to 150 people |
| Monthly gross burn | $500,000 to $2 million |
| Monthly net burn | $300,000 to $1.5 million |
| Typical ARR at raise | $5 million to $20 million |
| Target net burn as % of ARR | Under 50% annually |
| Top-quartile net burn as % of ARR | Under 30% annually |
| Median burn multiple | 1.5x to 2.0x |
| Top-quartile burn multiple | Under 1.2x |
Sources: Bessemer Venture Partners State of the Cloud 2025; SaaS Capital 2025 Private SaaS Survey; OpenView Expansion SaaS Benchmarks 2025
The Rule of 40 becomes a relevant gauge at Series B. It states that a SaaS company's revenue growth rate plus profit margin should equal or exceed 40. A company growing at 60% annually with a net burn of 30% of ARR achieves a Rule of 40 score of 30. The top quartile at Series B hits Rule of 40 scores above 50, per Bessemer.
SaaS Capital found the median Series B company burns 33% of ARR annually as net burn. The top quartile burns under 20%. Companies burning over 60% of ARR annually are typically investing aggressively in GTM for a land-grab market or are burning inefficiently, and investors will want to understand which.
Series C and beyond
Growth-stage companies raising Series C and beyond are expected to be approaching or at profitability on an operational basis, or to have a clear and credible path there.
| Metric | Benchmark |
|---|---|
| Typical ARR at raise | $20 million to $75 million+ |
| Target net burn | Breakeven or under 20% of ARR |
| Rule of 40 benchmark (top quartile) | 50 or above |
| Target gross margin (SaaS) | 70% or above |
Sources: Bessemer Venture Partners; KeyBanc Capital Markets 2025 Private SaaS Survey; Insight Partners portfolio benchmarks
Companies still burning more than 40% of ARR at Series C face meaningful investor skepticism unless operating in a capital-intensive market with strong network effects. The post-2022 shift in investor standards has been most pronounced at this stage: companies that raised Series C rounds in 2024 and 2025 had median Rule of 40 scores of 42, compared to 28 in 2021, per KeyBanc.
Startup burn rate benchmarks by industry
Burn rate norms vary significantly by industry because cost structures differ.
| Industry | Seed stage median monthly burn | Series A median monthly burn |
|---|---|---|
| B2B SaaS | $100,000 to $140,000 | $200,000 to $450,000 |
| Consumer / e-commerce | $120,000 to $200,000 | $300,000 to $700,000 |
| Fintech | $130,000 to $180,000 | $350,000 to $600,000 |
| Healthtech / digital health | $150,000 to $250,000 | $400,000 to $800,000 |
| Hardware / deep tech | $200,000 to $400,000 | $600,000 to $1.5 million |
| Marketplace | $100,000 to $175,000 | $250,000 to $500,000 |
Sources: PitchBook Venture Monitor Q1 2026; First Round Capital; CB Insights State of Venture 2025
Hardware and deep tech have structurally higher burn because of physical production costs, regulatory timelines, and longer development cycles. Healthtech burn is elevated for similar reasons: clinical validation, compliance, and longer sales cycles requiring more runway before revenue materializes. B2B SaaS consistently sits at the efficient end of the spectrum, which partly explains why it dominates venture investment volume.
Startup runway benchmarks
Runway is the output of burn rate and capital on hand. Investors have consistent expectations about minimum runway at any given moment.
| Stage | Minimum investor comfort | Optimal target | Danger zone |
|---|---|---|---|
| Pre-seed | 12 months | 15 to 18 months | Under 9 months |
| Seed | 15 months | 18 to 24 months | Under 12 months |
| Series A | 15 months | 18 to 24 months | Under 12 months |
| Series B+ | 12 to 15 months | 18 months | Under 9 months |
Sources: Y Combinator Default Alive calculator and guidance 2025; First Round Capital founder resource guides; Andreessen Horowitz 2025 fundraising guidance
Y Combinator's "default alive" framework asks a simple question: at the current burn rate and current growth rate, will the company reach profitability before running out of money? Companies that cannot answer yes are "default dead" and dependent on future fundraising to survive. YC tracks this metric across its portfolio and reports that most failed companies were default dead 6 to 12 months before they actually closed.
Benchmark data from Crunchbase shows that the median time between funding rounds for startups from seed to Series A is 19 months. That makes 18 months of runway the natural target: enough to raise the next round without entering fundraising mode from a distress position.
When runway drops below 6 months, investors perceive desperation risk. A founder raising with 5 months of runway has limited negotiating leverage and will typically face worse terms than one raising with 15 months. The gap in valuation between those two positions is often 25 to 40%, per Crunchbase analysis of 2024 to 2025 rounds.
Burn multiple benchmarks
Burn multiple, developed and popularized by David Sacks and Bessemer Venture Partners, has become the dominant capital efficiency metric in venture from 2023 onward.
Burn multiple = Net cash burned in period / Net new ARR in period
A lower number is better. A burn multiple of 1.0x means the company spends $1 of cash to generate $1 of new ARR, which is the threshold for strong efficiency at scale.
| Stage | Top quartile burn multiple | Median burn multiple | Bottom quartile |
|---|---|---|---|
| Seed / early | Under 2.0x | 2.5x to 4.0x | Over 5.0x |
| Series A | Under 1.5x | 2.0x to 2.5x | Over 3.0x |
| Series B | Under 1.2x | 1.5x to 2.0x | Over 2.5x |
| Series C | Under 1.0x | 1.2x to 1.5x | Over 2.0x |
Sources: Bessemer Venture Partners State of the Cloud 2025; SaaS Capital 2025 Private SaaS Survey; OpenView Expansion SaaS Benchmarks 2025
Bessemer's 2025 data across its cloud portfolio found companies raising Series B rounds in 2024 and 2025 that received strong valuations (above 10x ARR) had burn multiples of 1.3x or lower. Companies with burn multiples of 2.5x or higher received lower multiples and faced harder closes.
One nuance: burn multiple benchmarks assume the company has material ARR (typically over $500,000 annually). Pre-revenue or very early-revenue companies cannot calculate a meaningful burn multiple, and investors instead focus on gross burn per capita (gross burn divided by headcount) as an efficiency proxy.
Headcount as a burn driver
Payroll is the primary driver of burn rate at every stage. Industry data consistently shows that 60 to 80% of a startup's gross burn is labor costs.
KPMG's 2025 Venture Pulse report found the average Series A startup allocates 68% of gross burn to payroll, including salaries, benefits, and payroll taxes. At Series B, that figure drops slightly to 62% as non-headcount costs (infrastructure, marketing, facilities) scale faster than headcount.
This makes headcount planning the most high-leverage burn management decision a founder makes. Every engineering hire at $180,000 total compensation adds $15,000 per month to gross burn. A team of 20 engineers at market rate represents $300,000 or more in monthly payroll alone.
PitchBook's 2025 data on startup cost structures found:
| Cost category | Share of gross burn (Series A median) |
|---|---|
| Salaries and benefits | 65 to 70% |
| Software and infrastructure | 8 to 12% |
| Office and facilities | 4 to 8% |
| Marketing and demand generation | 6 to 10% |
| Professional services | 3 to 6% |
| Other | 2 to 5% |
Source: PitchBook 2025 Startup Cost Benchmarks
The implication for founders managing burn: decisions about hiring timelines and compensation structure have more impact on burn rate than any other category. Optimizing software spend or office costs produces single-digit percentage improvements. Adjusting headcount planning produces 20 to 40% changes in gross burn.
For early-stage startups managing costs before scaling a full internal team, virtual assistant services for startups offer a way to handle administrative, operations, and support workloads without full-time employee overhead. A virtual assistant typically costs $8 to $20 per hour versus $60 to $90 per hour fully loaded for a US-based employee in comparable roles.
Common burn rate mistakes and how they show up in data
Over-hiring ahead of revenue
CB Insights found that over-hiring before product-market fit is the single most common contributing factor in companies with burn multiples above 4.0x at Series A fundraising. The pattern is consistent: a founder raises $2 million at seed, immediately hires 12 people, burns $250,000 per month, and arrives at Series A conversations 8 months later with 3 months of runway and below-target ARR. Investors see a company in distress rather than a company in control of its trajectory.
Ignoring gross margin when calculating effective burn
Net burn against revenue does not account for the cost to generate that revenue. A company with $100,000 ARR that is also spending $80,000 to deliver that revenue has effective net burn significantly higher than its reported figure. SaaS Capital's 2025 data found companies that fail to reach Series B often have gross margins under 50% at Series A, masking the real cost structure with headline revenue numbers.
Failing to model burn increase from planned hires
Most startup financial models show current burn rather than projected burn over the hiring plan. If a Series A company plans to go from 20 to 45 people over 18 months, the burn model needs to reflect the ramp. Founders who raise based on current burn and hire to plan often find themselves with 10 months of runway instead of the planned 18.
Cutting burn too late
The flip side of over-hiring is cutting too late. Andreessen Horowitz's 2022 "Time to Act" memo, which became widely cited in the 2022 to 2024 cohort, found that most startups that failed to survive the market correction waited 3 to 5 months longer than the data warranted before reducing headcount. The survivorship cost of waiting is not linear: a 3-month delay at $300,000 monthly burn costs $900,000 in runway and may represent the difference between having time to raise and running out of time entirely.
How to benchmark your own burn rate
Five calculations worth running against your own numbers:
1. Calculate net burn, not just gross burn. Subtract all recurring revenue (including MRR from monthly contracts, not ARR projections) from gross monthly outflows. Use the last 90 days' average to smooth monthly variation.
2. Calculate burn multiple if you have material ARR. Divide net cash burned over the last 12 months by net new ARR added over the same period. Compare to the stage benchmarks above.
3. Calculate runway at current burn. Divide cash on hand by monthly net burn. If you have runway below 12 months and are not yet at series-round velocity for the next raise, treat it as an emergency regardless of growth metrics.
4. Model burn 12 months forward. Account for all planned hires, salary increases, and growth in non-headcount costs. Many founders are surprised to find their runway shrinks from 18 to 10 months when they model the actual cost of their hiring plan.
5. Compare gross burn per capita to stage benchmarks. If gross burn divided by headcount significantly exceeds $18,000 to $22,000 per person per month at seed stage, review compensation levels and whether all roles are necessary.
For founders managing operations and finance with a lean internal team, outsourced back-office and operations support can handle bookkeeping, financial reporting, and administrative overhead at a fraction of full-time hiring cost. That keeps burn lower while maintaining the operational infrastructure investors want to see.
What investors look at alongside burn rate
Burn rate in isolation is not how investors evaluate capital efficiency. The number they care about is burn rate relative to growth.
Revenue growth rate is the most important modifier. A company burning $400,000 per month with 150% annual revenue growth is capital-efficient. A company burning $400,000 per month with 30% growth is not.
Gross margin matters because high burn against low-margin revenue is worse than the same burn against high-margin revenue. If gross margin is below 50%, every dollar of ARR carries significant cost of delivery, and net burn understates what it actually takes to maintain that revenue. SaaS Capital flags sub-50% gross margin as a Series B red flag for exactly this reason.
Sales efficiency (sometimes called the magic number) measures how much ARR is generated per dollar of sales and marketing spend. Over 1.0x is considered good; 0.75x to 1.0x is acceptable; under 0.5x requires explanation.
CAC payback period rounds out the picture. It measures how many months of gross margin dollars are needed to recover the cost of acquiring a customer. Under 12 months is strong at Series A. Over 24 months tends to come up in Series B diligence as something that needs addressing before the next round.
Tracking these metrics alongside burn rate is the standard practice for founders preparing for a raise. Investors who see a high burn multiple will immediately ask about the underlying unit economics. Having that data prepared demonstrates financial sophistication and improves the quality of fundraising conversations.
Burn rate and the path to profitability
For startups approaching Series C or considering alternative paths to growth (bootstrapping, revenue-based financing, or profitability before a later round), the burn rate conversation shifts from "how efficient is your growth" to "when do you turn the corner."
SaaS Capital's 2025 data found the median path from seed to breakeven for SaaS companies that did not raise a Series B is 52 months from first revenue to cash flow positive. Companies that maintain burn rates at or below stage benchmarks reach that milestone significantly faster: the top quartile achieves breakeven in 34 months.
For companies on the venture path, the relevant question is whether each dollar of burn produces enough compounding value (ARR, customer relationships, market position) to justify the dilution required to raise the next round. The benchmarks above provide the reference points for that conversation.
For a closer look at the cost side, see our research on startup staffing costs or virtual assistant services for startups, which covers how early-stage teams manage headcount overhead without full-time hiring.
Summary: startup burn rate benchmarks 2026
| Stage | Monthly net burn (median) | Burn multiple (top quartile) | Minimum runway target |
|---|---|---|---|
| Pre-seed | $10,000 to $45,000 | N/A (pre-revenue) | 15 months |
| Seed | $50,000 to $150,000 | Under 2.0x | 18 months |
| Series A | $150,000 to $400,000 | Under 1.5x | 18 months |
| Series B | $300,000 to $1.5 million | Under 1.2x | 18 months |
| Series C | Approaching breakeven | Under 1.0x | 15 months |
Investors read burn rate as a signal about how well a founder understands the business. It tells them whether the cost structure is intentional or accidental. Founders who track it closely tend to manage it well. Founders who treat it as a reporting artifact rather than a decision variable are usually the ones who show up at Series A with 3 months of runway and no explanation for where it went.
Statistics reflect data from PitchBook, CB Insights, Bessemer Venture Partners, SaaS Capital, Crunchbase, KPMG Venture Pulse, KeyBanc Capital Markets, OpenView Venture Partners, Andreessen Horowitz, and Y Combinator as of mid-2026.

Frequently Asked Questions
What is a good burn rate for a startup?
A good burn rate depends on stage. At seed, a net burn under $100,000 per month is considered efficient. At Series A, under $250,000 per month with a burn multiple below 1.5x is a strong position. The key is the ratio of burn to new ARR generated, not the absolute number.
How do you calculate startup burn rate?
Net burn rate equals gross monthly cash outflows minus recurring monthly revenue. Track the last 90-day average to smooth monthly variation. Runway is cash on hand divided by monthly net burn.
How much runway should a startup have?
Y Combinator and most Series A and B investors expect 18 months of runway after each funding round, with a hard floor of 12 months at any given time. Below 6 months of runway is a distress signal that materially weakens fundraising leverage.
What is a burn multiple and what are the benchmarks?
Burn multiple is net cash burned divided by net new ARR in the same period. Bessemer Venture Partners benchmarks: under 1.5x is good at Series A, under 1.2x is good at Series B. Above 2.5x at Series A or above 2.0x at Series B will face investor scrutiny.
