What Is a Good Burn Multiple for a Startup

All right, here is the direct answer. Burn multiple is net burn divided by net new ARR: how many dollars of cash your startup burns to add one dollar of new recurring revenue. Below 1.0x is exceptional, 1.0x to 1.5x is strong, and above 2.0x draws hard questions at Series A in 2026.

Now let me tell you why that little ratio has taken over your board deck. For a decade the growth slide was the main event and the burn slide was housekeeping. That order has flipped. CRV, a Series A firm that has been writing first checks for fifty years, opens its founder guidance with exactly that moment: the first time you realize the burn slide will get more questions than the growth slide.³ Burn multiple is the reason. It is the price tag on your growth, printed where everyone can read it.

So let me walk you through it the way I would on a call. Where the metric came from and why it won. How the calculation works, because the word "net" is doing all the work in both halves of the fraction. What good looks like by stage, with honest caveats about where those benchmarks come from. How investors read it, the ways it can lie to you, and what actually moves it.

Where this number came from, and why it stuck

The burn multiple is young for something this load bearing. David Sacks of Craft Ventures coined it in April 2020, in the early weeks of the pandemic, as a way to judge whether a startup's burn was justified by its growth. His framing is still the cleanest one written: the ratio asks "how much is the startup burning in order to generate each incremental dollar of ARR?"¹ A company that adds $1 million of ARR while burning $2 million looks like the market is pulling the product out of it. A company that burns $5 million for the same result is pushing.

Sacks did not invent the idea from scratch, and he says so. Bessemer Venture Partners had been publishing an Efficiency Score, the same fraction upside down: net new ARR divided by net burn.²⁴ Before that, Dave Kellogg proposed the Hype Factor on the observation that "SaaS companies convert venture capital into two things: annual recurring revenue (ARR) and hype."⁵ Sacks flipped Bessemer's ratio so the spotlight lands on the burn, and the flipped version won the language war. By 2022 his own partner Jeff Fluhr could write that "The Burn Multiple has become the de facto standard for evaluating the efficiency of growth for SaaS businesses."²

Why did this one stick when finance has no shortage of efficiency ratios? Because it is a catch-all. A gross margin problem inflates burn as you scale. A sales efficiency problem inflates burn relative to new ARR. A churn problem quietly eats the denominator, since churned revenue nets against your new sales. Any serious disease in the business eventually presents in this one number, and as Corporate Finance Institute's textbook treatment puts it, "A low burn multiple indicates that a company is generating revenue efficiently relative to its spending."²⁵ One number, and it is hard to spin.

The one word doing all the work: net

The formula is net burn divided by net new ARR, and both halves are easy to get wrong. Start with the top. Gross burn is everything going out the door in a month: payroll, rent, software, marketing, all of it. Net burn subtracts the cash coming in.²¹ Carta's definition is the one I would frame: "Net burn rate is the actual cash loss per month, calculated as total expenses minus revenue."¹¹ A company spending $350,000 a month against $200,000 of revenue has a gross burn of $350,000 and a net burn of $150,000, and it is the $150,000 that goes in the fraction.³

The bottom half nets out just as much. Net new ARR is new customer ARR, plus expansion from existing customers, minus downgrades and churn.²⁵ That last subtraction is the trap. You can sign a record class of new customers and still post a weak burn multiple, because churn clawed half of it back before the number ever reached the page. The metric is quietly grading your retention every time you calculate it, which is exactly why investors trust it more than a gross bookings figure.

Put the halves together with real numbers. Burn $150,000 a month and you burn $1.8 million a year. Add $1.2 million of net new ARR over that year and your burn multiple is 1.5x. Now suppose growth halves to $600,000 while spending stays put: the same burn produces a 3.0x multiple, and you have moved from acceptable to alarming without cutting a single check differently.³ The ratio punishes stalled growth exactly as hard as overspending, because to the person wiring you money those are the same disease.

Two bits of hygiene before yours goes in a deck. Measure over a window long enough to smooth the noise; Mercury's guide recommends a trailing average and warns that one-time items, annual prepayments and deferred revenue can distort any single month.²² And if you run a marketplace or anything seasonal, use the year over year version and swap gross profit growth for ARR growth, as Craft Ventures itself recommends, because a seasonal trough will hand you a negative multiple that means nothing at all.²

What good looks like in 2026, stage by stage

Here is the benchmark picture, and I want to be upfront about its nature before you screenshot it: these are investor rules of thumb and published stage guides, not audited medians. The most useful current version in a named investor's own words comes from CRV. Their tiering runs: below 1.0x is exceptional territory, 1.0x to 1.5x is strong, 1.5x to 2.0x is acceptable at Series A while you prove the model, 2.0x to 3.0x is concerning, and above 3.0x is problematic.³

That maps onto the rule of thumb in circulation since the original essay, which Klipfolio's metrics newsletter states plainly: "less than 1X is amazing, between 1 to 1.5X is great, up to 2X is good."⁸²⁶ Grading burn against company size is an older instinct still; OpenView was publishing burn benchmarks by ARR scale back in 2019.²⁷ By stage, the picture looks like this.

The seed, B and C ranges come from Data Driven VC's 2025 synthesis of the published guidance, which is also where the "about 1.2x or better" Series A target lives.⁷ Survey data corroborates the direction. Benchmarkit's 2025 report, built from 563 participating private SaaS companies, states that "The Burn Multiple decreases as a company scales with the goal to reach < 1.0 at the $25M - $50M range" and should eventually go negative, meaning you add ARR while generating cash.¹⁹ Tomasz Tunguz's survey work found the same convergence: "The majority of the surveyed population plans to operate with burn multiple of 1.5 or less."¹⁰ For marketplaces on the gross profit version, Craft Ventures draws the cut line at 2.5.²

You will also find gentler tiers out there. Mercury's guide, written for a broader small business audience, holds that "A burn multiple under 2x is generally considered efficient."²² Both things can be true. Under 2x keeps the lights on and the bank comfortable. Under 1.5x is what the venture market now rewards, and the gap between those two sentences is roughly the gap between running a business and running a fundraise.

How investors actually read it

CRV calls the burn multiple "the defining efficiency metric of the current fundraising environment,"⁴ and the environment is what changed, not the arithmetic. The median publicly traded SaaS company crossed into operating profit in early 2026; SaaS Capital, which has tracked that index for years, reports that "For the first time in more than a decade, the median company in the SCI is generating an operating profit," up from negative 21 percent in mid 2022.¹⁷ When the public comparables run profitably, private investors stop underwriting the old playbook. Pavilion's benchmark report opens with the sentence every founder has now heard in some form: "The growth-at-all-costs era is over."¹⁴

The squeeze is measurable on both sides of the fraction. Acquisition got dearer: Benchmarkit's data has the new customer CAC ratio rising 14 percent in 2024, to $2.00 of sales and marketing spend per dollar of new ARR.¹⁴ Lighter Capital, working from connected accounting data on 155 private startups rather than a survey, found that "Sales and marketing dollars went half as far to generate SaaS revenue in 2025."²⁰

Meanwhile the AI cohort reset the pace of the denominator. In a16z's sample the median enterprise AI company reached over $2 million of ARR in its first year and the median consumer AI company hit $4.2 million; their summary is five words long: "Speed is becoming a moat."⁹ ICONIQ's 2025 report finds AI-native companies outperforming on burn multiple specifically, and concludes that across its dataset "efficient growth has emerged as the dominant signal."¹³ Read together, that is why the bar sits where it sits, and why only about one in five seed-funded startups now reaches a Series A.⁷

The single most useful thing to know is that investors read this number as a movie, not a photograph. A multiple that declined from 2.5x to 1.6x, with each inflection tied to a decision you can name, beats a flat 1.4x nobody can explain. CRV describes the founders it backs as sharing one habit: "they treat every dollar as a decision, not an expense line."³ The trend is the credential. The snapshot is just where the trend happens to be standing today.

It travels with a companion, too. The Rule of 40, which Brad Feld popularized in 2015, says "The 40% rule is that your growth rate + your profit should add up to 40%."¹⁶ Burn multiple is the early-stage instrument, Rule of 40 the at-scale one, and ICONIQ now ranks Rule of 40 as the most reliable predictor of public software valuations.¹³ Under roughly $15 million to $20 million of ARR, expect the burn multiple conversation. Past it, expect both.

Where the number lies to you

Every clean metric has failure modes, and this one has four worth naming. First, the good-number trap. Jason Lemkin at SaaStr wrote a whole piece on founders who treat a strong ratio as a health certificate, and his warning is blunt: "You can still run out of money even at 1x."⁶ A burn multiple has no opinion about your bank balance. It also quietly assumes software-grade gross margins around 75 to 80 percent, retention above 100 percent, and a next round that actually arrives. Weaken any of those and the same 1.2x is a much worse fact than it looks.

Second, the negative-number illusion. If churn exceeds new sales, or a seasonal business hits its trough quarter, the denominator goes negative and the ratio produces nonsense that can masquerade as excellence in a spreadsheet, which is exactly why Craft Ventures tells marketplace founders to compute it year over year on gross profit.² Third, window dressing. Because the inputs are cash, you can dress up a quarter by stretching payables or collecting a year of prepayments up front.²² Your investors have seen every version of this, and the first diligence pass on a suspiciously good multiple is a month by month cash walk.

Fourth, and this is the subtle one, you can cut your way to a beautiful ratio and a dead company. Growth spend that returns nothing should absolutely go. But Feld's old warning applies to the founder who slows to 20 percent growth to show 20 percent profit: you will simply be sub-scale for longer.¹⁶ First Round's glossary states the balance in one line: "A healthy burn rate balances growth with sustainability."²³ The goal was never a low multiple. The goal is efficient growth, or as Wall Street Prep frames the whole exercise, "Over the long run, efficient growth is more stable and reliable than growth that comes with unsustainable spending."²⁴

The dilution math nobody puts on the slide

Here is the part founders feel last. The cash you burn was not free. You bought it with ownership. Carta's 2026 Founder Ownership Report, drawn from its cap table data on rounds from 2021 through 2025, finds the median founding team holds about 56 percent of fully diluted equity by the seed round, and "By the time it raises a Series A, median founder ownership declines to 36%."¹⁸ Every dollar of unnecessary burn is a dollar you will eventually replace by selling more of your company. That is what the burn multiple is really pricing: not spending, but dilution per dollar of durable revenue.

The cumulative version of this idea is Bessemer's Cash Conversion Score, current ARR divided by total capital raised net of cash. In Bessemer's portfolio, financings made above a 1.0x score returned an average IRR of 120 percent, and their conclusion is the sentence I would tape to the monitor: "raise money only when it will drive returns."¹² The burn multiple is the quarterly speedometer; the cash conversion score is the odometer. A good quarter can hide a wasteful history, so investors increasingly check ARR per total dollar raised alongside the in-period number.⁷

I will tell you where my own conviction on this comes from. I spent about five years as Controller and then EVP of Financial Operations at a fertility pharmacy that we built from concept to a $50 million operation with about 40 state permits, sold to private equity in roughly four and a half years. Growing that fast, every dollar is so precious. The discipline was never "spend less." It was knowing, every single week, what each category of spending was buying us in growth, and killing the spend that could not answer the question. That is the burn multiple conversation, just held before the metric had a name.

How to bring it down without starving growth

Because both halves of the fraction move, you have more levers than a cost cut. The cheapest one is hiding in your existing customer base. Benchmarkit's 2025 data puts the expansion CAC ratio near $1.00 against $2.00 for brand new customers, and Ray Rike's read of the data notes that "B2B SaaS companies generate 40% of their Total New ARR from existing customers."¹⁵ A dollar of expansion ARR costs about half what a dollar from a new customer costs and lands in the same denominator. If your multiple is ugly and net revenue retention sits below 100 percent, fix retention first, because churn double-bills you: it takes the revenue, then poisons the ratio you show investors.

Then work the classics, biggest lever first. Gross margin, because a point of COGS saved improves burn at every level of scale, and because the metric silently assumes software margins you may not have yet. Customer acquisition cost by channel and cohort, since stretching CAC payback is where most bad multiples are manufactured.³ Pricing, the fastest margin lever most founders refuse to pull. And headcount plans that trail proof rather than lead it. What you should not do is chase the ratio with cuts that starve the growth engine. Sacks built the escape hatch in deliberately: the burn multiple resets every period and does not care about sunk costs, so improvement can start this quarter.¹

Operationally, this lives in two documents you should already have. The burn multiple belongs in the monthly reporting package next to runway, computed on the quarter and the trailing twelve months so one lumpy month cannot spin the story. The cash side belongs in a 13-week cash flow forecast, because the ratio says whether growth is efficient while the forecast says whether you make payroll, and the second question always outranks the first.⁶ If you run a technology or AI company answering to a board, this pair is the minimum instrumentation.

The number is the start of the conversation, not the end of it

So, what is a good burn multiple for a startup? Under 1.5x puts you in strong company at Series A, under 1.0x puts you in rare company at any stage, and above 2.0x means you should be able to explain, line by line, what the extra burn is building. But the better answer is a multiple you can decompose. Which dollars bought which growth. Which experiments earned more funding, which got shut down, and what the trend has done for four straight quarters.

That is a finance function's job, and plenty of companies between $2 million and $50 million of revenue do not have one yet. If the numbers in this piece raised questions about your own, that is a good instinct, and it is worth asking someone before the pitch meeting rather than during it. Ultimately you are the captain of the ship and you have to do what is best for the business. The job of the person on your numbers is to make sure you are deciding from clarity, not fear.
