SaaS Marketing Budget Benchmarks for 2027: The State of B2B SaaS Marketing Budgets

What does each primary survey actually say?

Four publishers run the surveys a SaaS marketing budget can be planned from. Side by side:

By size, a few cuts come from a survey. None of the surveys we read cuts by funding stage, so the stage bands in circulation are a rule of thumb.

Why do the medians disagree? Mostly the denominator and the population. SaaS Capital divides by ARR. Benchmarkit, Gartner and the CMO Survey divide by revenue. The two bases pull apart in both directions: revenue adds services and usage income that ARR leaves out, while ending ARR runs ahead of trailing revenue at a company that is growing. The same spend gives a different percentage on each. Gartner's sample is mostly billion-dollar companies across industries, and its figure sits close to B2B Product firms in the CMO Survey (7.0%). Benchmarkit compares planned budgets, while SaaS Capital asks what companies currently spend. Read 8%, 9% and 7.8% as answers to different questions.

What do AI engines tell founders to spend?

On 9 November 2026, ChatGPT, Perplexity, Gemini and Google's AI Overview gave a marketing-spend percentage in 91 of 120 answers to 30 budget questions, and only 18 of those 91 tied the number to a named primary survey. SaaS Capital's survey was named as the source of a marketing-spend figure in 21 of the 120 answers; the agency seed-stage band, 15-25% of ARR or revenue at seed, pre-product-market-fit or early stage, appeared in 12.

The engines agree on a midpoint. The median headline figure was 10% pooled, with a median range of 8% to 14%. By engine, the midpoint was 10% for ChatGPT and Perplexity, 11.5% for Gemini and 11.75% for Google's AI Overview. 8% is the anchor: 48 of the 91 answers that gave a figure opened on exactly 8% or a range starting at 8%.

Ask "how much should a $5M ARR SaaS company spend on marketing" and the answers split:

• Google AI Overview: 15% to 50% of ARR
• ChatGPT: 10-20%
• Gemini: 8% to 20%
• Perplexity: 8%

The sourcing is thin. 61 of the 91 answers with a figure named no source in the text on any line carrying a number. Perplexity did this in 20 of 22, even though it linked sources under every one of its answers. Under our strict rule, the share that traced to a primary survey ran from 37.5% on ChatGPT (9 of 24) to 9.1% on Perplexity (2 of 22). Only 9 of the 120 answers named a survey with a year next to a figure.

Mixing denominators is routine: 65 of 120 answers (54.2%) also put a combined sales-and-marketing figure in the reply, a second percentage that measures a different budget.

What the engines read explains what they say. Across the 120 answers they cited 757 URLs:

Perplexity cited 0 primary publishers in 300 citations. ChatGPT cited little (it ran a web search on only 18 of 30 questions), but 12 of its 30 citations went to primary publishers, and saas-capital.com was its most-cited domain. Google's AI Overview, which appeared on all 30 of 30 budget searches, took 21.6% of its citations from forums and social sites, with LinkedIn in 13 of the 30 overviews. That matches what we see across our own category: each engine trusts a different corpus, and the answer repeats whichever pages it retrieved. If three in four sources are agency blogs, the agency blogs set the number.

How did we run the AI answer study?

Panel. 30 budget questions written the way a founder types them, frozen before any data was pulled. The cuts: overall (4), percent of revenue or ARR (3), stage (seed 2; Series A, B and C one each), ARR size ($1M, $5M, $10M, $20M), bootstrapped vs VC (2), PLG vs sales-led (3), channel split (2), SEO (2), AI search, AEO or GEO (2), 2027 planning (2) and sales plus marketing combined (1).

Engines and settings. Each question went verbatim to four engines through DataForSEO on 9 November 2026, between 07:53:29 and 07:56:58 UTC:

One answer per question per engine: 30 each, 120 in total. No endpoint failed. The LLM calls carried no system prompt or history.

Counting rules. The headline figure is the first marketing-only percentage of ARR or revenue in the answer's prose. A range counts at its midpoint. Any figure on a sales-and-marketing line is recorded separately and never used as the marketing headline. An answer "traces to a primary survey" only when it names a primary publisher beside its headline figure, or cites that publisher's site and names it in the text. A benchmark band or a named survey counts only where the answer states it as total marketing spend as a share of ARR or revenue. The base must be ARR or revenue for every count, headlines included; an operating-budget base does not count. A stage band counts as the agency's band only where the answer attaches it to the agency's stage, so 15-25% counts as the seed band only next to seed, pre-PMF or early stage, and a growth posture such as "aggressive VC-backed growth" does not count; a channel's share of the marketing budget does not count, and we read every line carrying a benchmark figure by hand to judge that. Citations are counted as URL-answer pairs. Each cited domain was classed from its homepage title: primary publishers, forums and social sites, and media or reference sites were listed by hand, and every other domain was reviewed and defaulted to agency or vendor.

Checks. Using the first bold figure instead of the first figure in prose changes 12 of the 91 headlines; the pooled median stays at 10%. A second ChatGPT pass on the first 10 questions, same settings, matched the headline figure in 4 of 10. We tightened the counting rules after the pull, while checking answers by hand against the counts; under the rules as first written, 95 of 120 answers gave a figure and the pooled median was still 10%. The seed-band count of 12 is sensitive to two calls: reading one Google answer's "Early-Growth / High-Growth SaaS (Pre-Scale or Scaling)" line as seed gives 13, and also accepting another Google answer's "operating budget/revenue" base gives 14. A stricter reading cuts it: dropping two Gemini labels that span seed and Series A gives 10, and also dropping two labels that pair early stage with a growth posture gives 8. SaaS Capital's 21 leads either way.

Limitations. One answer per question per engine is a snapshot, and the ChatGPT rerun kept only 4 of 10 headlines. API answers can differ from what a signed-in user sees in the apps. Google is one US desktop location. Two lenders that publish benchmarks from their own customer data, Lighter Capital and Founderpath, are counted under other sources; counting them as primary would raise the primary share slightly. The panel is 30 hand-written questions rather than a sample of query logs. Disclosure: loudface.co was cited in 4 of the 120 answers, and those answers are included in the counts.

Where do the 15-25% stage bands come from?

The earliest-dated page we found carrying them is an agency's, and no survey sits behind it. We followed the trail back:

1. GrowthSpree published the exact bands on 23 May 2026: 15-25% at seed or pre-PMF, 12-18% at Series A, 11-16% at Series B, 10-14% at Series C and 8-12% at Series D and above. The page says the figures come from "$60M+ in managed B2B ad spend across 300+ companies", calibrated against HubSpot, OpenView and Sales Hacker reports it does not link. No survey, named sample or collection date backs the bands. A second GrowthSpree page, dated April 2026, gives higher ranges for the same stages (25-40% at seed, 20-30% at Series A), so the agency's own figures moved between April and May. We found no earlier-dated page with the exact bands, which is not proof that none exists.
2. The Zulu Method printed the same five bands on 30 June 2026 and credited "GrowthSpree's percent-of-ARR-by-stage benchmarks and Stackmatix's stage-by-stage guide".
3. Stackmatix's guide, in its current version dated 11 September 2026, has no percent-of-ARR bands at all. It gives dollar ranges per month by round, such as $30,000-$100,000/month at Series A, and cites no survey. Its one total-budget percentage, 15-25% at Series B, is a share of total operating expense, not of ARR; its other percentages split the marketing budget by channel.
4. SaaSHero repeats the bands with no attribution, after a sentence saying "Benchmark reports provide marketing budget ranges by stage" that names no report.

Google's AI Overview then cites the Zulu page and presents the bands as a benchmark. In our panel, the seed band (15-25% of ARR or revenue, attached to seed, pre-PMF or early stage) appeared in 12 of 120 answers: ChatGPT 1, Perplexity 4, Gemini 4 and Google's AI Overview 3. SaaS Capital was named as the source of a marketing-spend figure in 21: ChatGPT 6, Perplexity 2, Gemini 6 and Google's AI Overview 7. The survey leads overall and on three of the four engines; the band leads only on Perplexity, 4 to 2. Counted at any stage or posture, 15-25% appeared as total marketing in 19 of 120 answers, a separate measure from the seed band. Another 20 answers carried the string "15-25%" for something else, such as a channel's share of the marketing budget or a share of a seed round, and two Google lines with an unclear or operating-budget base were left out.

The engines' own stage answers sit inside the agency bands: a pooled median of 16.25% for Series A, 13.25% for Series B and 12% for Series C (4 answers per stage, so indicative only). The later agency bands rarely appear at all: 12-18% sat next to Series A in 8 of 120 answers, 11-16% next to Series B in 4 and 10-14% next to Series C or later in 5. Only 12-18% often turns up at another stage; it appeared in 17 answers, and 8 of those put it at Series A.

Nobody can say whether the bands are wrong, because nothing published lets you check them. They describe how one agency's ad clients spend. That is a fair thing to publish, and without a named sample it is not a benchmark.

Which pages misquote the surveys?

For each row we read both the page and the primary source it cites, on 9 November 2026.

Aimers quotes SaaS Capital's 2025 equity-backed figures correctly. The common fault is year drift: the figure survives while its edition changes.

Is 8% marketing only, or sales and marketing combined?

Marketing only. SaaS Capital reports marketing (8% of ARR) and selling (15%) as separate lines and publishes no combined figure. Adding them gives 23% of ARR, our sum rather than theirs.

In its SaaS metrics series, Benchmarkit puts median S&M at 35% of revenue in CY-25, down from 37% the year before and the first decline in that series. Benchmarkit's marketing report says marketing is 30% of the combined budget. Apply 30% to 35% and you land near 10.5% of revenue, in line with its own marketing medians.

When a page or an AI answer says early SaaS companies spend "80-120%", that is a combined sales-and-marketing figure, and it is older than the pages repeating it. Tomasz Tunguz published it in 2013 for public SaaS companies in their first three years, from a small set (n=30, in his words), and warned that survivorship bias skews it. SmartBug Media relays it with his name but without that scope. Aimers gives it for pre-Series A companies, under a line saying it pulled data from its clients and industry benchmarks, with no credit to Tunguz. It showed up in 2 of our 120 answers, both Google AI Overviews and both on the combined sales-and-marketing basis. Each line cites several pages: SmartBug is among the sources of one, Aimers among the sources of the other. Neither copy traces to a survey.

Do bootstrapped and equity-backed companies budget differently?

Yes, by a factor of about two on marketing. SaaS Capital's 2026 edition says equity-backed companies spend 100% more on marketing, 70% more on sales and 56% more on R&D than bootstrapped ones. Its chart puts marketing at 5% of ARR for bootstrapped companies and 10% for equity-backed.

The extra spend comes with somewhat faster growth (a median 25% for VC-backed companies against 20% for bootstrapped) and more losses: 48% of equity-backed companies operated at a loss, against 17% of bootstrapped companies. Total spend was 96% of ARR for bootstrapped companies and 101% for equity-backed ones, down from 107% a year earlier.

Benchmarkit's 2025 metrics report shows a similar gap by ownership on combined spend, though its comparison is VC-backed against PE-backed companies: S&M at 47% of revenue against 33%.

If you are bootstrapped, 5% of ARR is the survey median and 8% is a median that includes funded peers. Plan from the one that matches your cap table.

Do PLG companies spend more on marketing than sales-led ones?

In Benchmarkit's data, yes. Its 2025 report shows product-led companies at a median 10% of revenue on marketing in 2024 against 8% for sales-led companies. For 2025, product-led companies planned 13%, sales-led 10% and hybrid 10%.

By pricing model, the same report puts subscription companies at a median 10% of revenue on marketing in 2024 against 6% for usage-based ones, a gap it says continues in the 2025 budget. Its text reports hybrid-pricing budgets rising in 2025 but gives no hybrid number for that year; a summary table elsewhere in the report shows hybrid at 6% without saying which year. Payback also moves with deal size. In Benchmarkit's 2026 SaaS & AI-Native Metrics report, median CAC payback is 11 months under $5K ACV and 22 months in the $50K-$100K ACV band.

How do you back-solve a budget from CAC ratio and payback?

Start from the new revenue you need, then multiply by what it costs to buy. This is worked arithmetic rather than a benchmark. The two inputs come from Benchmarkit's 2026 reports:

• New-name CAC ratio: a median $1.63 of S&M for every $1 of new-customer ARR, with the 25th percentile at $1.14.
• Marketing's share of S&M: 30% across the population.

Multiply them: at the median, every $1 of new-customer ARR needs about 49 cents of marketing spend ($1.63 x 30%). At the 25th percentile it needs about 34 cents ($1.14 x 30%). Your marketing budget as a share of ARR is then your new-customer ARR target times that rate.

In dollars:

• $5M ARR, targeting $1.25 million (25%): S&M of about $2.04 million, marketing about $611,000. At the 25th percentile, marketing is about $428,000.
• $20M ARR, targeting $3 million (15%): S&M of about $4.89 million, marketing about $1.47 million.

Read the 15% row against SaaS Capital's 8% median: a company at median efficiency spending 8% of ARR on marketing is buying new-customer ARR worth roughly 16% of its base, before churn and expansion. If your plan asks for more, either the budget goes up or the CAC ratio has to come down.

Before you use this, adjust three things. Marketing's share of S&M was 40% at $5–20M in Benchmarkit's 2025 report and 35% for companies growing over 20% in 2026, so swap in the share that fits you. Check the result against payback: Benchmarkit's median CAC payback was 16 months in CY-25, improved from 18. And High Alpha's report warns that early-stage companies do not always count every acquisition cost, which can flatter their payback. For the channel-level version of this math, see the ROI math on SEO, AEO and CRO.

Where do SEO and AI search fit in the budget?

As a line item for the first time. Benchmarkit's 2026 marketing report says AEO and GEO did not appear as a meaningful line in 2025 budgets, and that "In 2026, AEO was established as a budget line item" (N = 92). Smaller companies put a larger share of their marketing budget into it than larger ones, and the report expects money to keep moving toward AEO and GEO through the second half of 2026 and into 2027. The same report says content, SEO and AEO spend that drives high-intent inbound should be protected even as budgets compress.

Two other figures get quoted here, and both need a label:

• A vendor survey. Conductor, which sells an AEO platform, reports that enterprises allocated an average of 12% of their digital marketing budgets to AEO/GEO in 2025, from a survey of more than 250 senior executives. The denominator is the digital budget rather than the whole marketing budget.
• A forecast. Gartner predicted in February 2024 that "By 2026, traditional search engine volume will drop 25%", a prediction rather than a measurement.

The AI engines themselves barely mention the line. In our panel, SEO came up in 67 of the 104 answers to questions that did not ask about SEO or AI search. AI search, AEO or GEO came up in 9 of those 104. Perplexity mentioned it 0 times in 26. When an engine did put a number on it, the number was usually a share of an existing budget: ChatGPT suggested 10-25% of the SEO and content budget, Perplexity 10-20% on top of the organic-search budget.

Our view: budget AI search the way you budget any acquisition channel, against pipeline, signups and booked demos, back-solved from what a customer is worth to you. Track share of answer as an early read, and judge the line on the pipeline it produces. A page an engine never retrieves never gets named, so the line has to pay for pages buyers' questions actually pull up. For what that work costs, see AEO agency pricing for B2B SaaS, AI visibility tool pricing and how to measure AEO agency ROI.

LoudFace publishes its pricing: engagements start from $5k/month (see pricing). The SEO and AEO program ties its goals to pipeline and reports results in leads. For SaaS companies, see SEO for SaaS.

How should you set the 2027 marketing budget?

Match the benchmark to your cap table and denominator, then let your growth target overrule it.

1. Choose the matching benchmark. SaaS Capital's 10% of ARR if equity-backed, 5% if bootstrapped, or Benchmarkit's band for your size if you plan in revenue.
2. Back-solve from new-customer ARR. Use your own CAC ratio once you have the data. Only 46% of marketing teams in Benchmarkit's 2025 report measured cost per dollar of new-logo ARR, so this step alone puts you ahead of most peers.
3. Split people, programs and tech. Benchmarkit's 2026 plan median puts people at 46%, programs at 40% and technology at 10% of the marketing budget. Gartner's labor share rose to 24.5% in 2026, on a different scheme.
4. Give AI search its own line. Benchmarkit saw AI's share of the marketing budget rise from 2% to 5%, and AEO became a line item in 2026. Size it from pipeline rather than from a percentage an engine recited.
5. Write down the source and year of every number you show the board. Every page in the correction table above got a year, a sample, a source or a denominator wrong.

When the back-solve and the median disagree for 2027, plan from the back-solve. The median describes peers' budgets; the back-solve prices the growth you have promised your board. If that price looks too high next to the median, work on the CAC ratio before you cut the target.
