How much should a B2B SaaS company spend on marketing in 2027?

It is budget season, so on almost every call somebody asks the same thing. How much should we put behind marketing next year?

Nobody asks it cold. They have usually been Googling first or asking ChatGPT, Gemini, Perplexity and Claude to research and generate a marketing roadmap for 2027, and they arrive with three tabs open, three different percentages, and no idea which to trust.

So I went and collected them. If you are between $2M and $10M ARR, the published answers run from 5% of ARR to 30% of ARR. At $5M, that is the difference between a $250,000 marketing budget and a $1.5 million one, both presented as the industry standard.

They are not all wrong. They are measuring different things, and only one of them describes what companies actually do.

What do B2B SaaS companies actually spend on marketing?

The best available answer comes from SaaS Capital’s 2026 spending benchmarks, its fifteenth annual survey, completed in March 2026 across more than a thousand private B2B SaaS companies.

Median marketing spend: 8% of ARR, unchanged year on year. Median selling costs: 15% of ARR, up from 13%.

Before you write 8% into a spreadsheet, you need to know what sits around it.

Marketing is one of the smaller department lines. Research and development runs at 24%, general and administrative at 15%, customer support and success at 9%. If 8% feels low next to what you were planning, that is because the number does less work than people assume.

Selling went up and marketing did not. Selling costs rose from 13% to 15% of ARR in a year while marketing stayed flat. If you are building a 2027 number, the recent movement in this industry has been on the sales side.

Together they come to about 23% of ARR. That is the figure to compare against, not the 8% on its own, because most budget conversations blur the two.

Why do other marketing budget guides say 15 to 30% of ARR?

Here are their numbers, by stage. The reason they look like this is in who publishes them.

Stage	ARR	Marketing budget as % of ARR
Pre-seed and seed	Under $2M	15 to 25%, some sources 25 to 40%
Series A	$2 to 10M	12 to 18%, some sources 20 to 30%
Series B	$5 to 15M	11 to 16%
Series C	$15 to 30M	10 to 14%
Series D and beyond	$30M+	8 to 12%

Now here is what SaaS Capital found when it asked a thousand companies what they actually spend.

Companies between $3M and $5M ARR: 8% of ARR on marketing, 12% on selling. Companies under $3M ARR: around 5% on marketing.

Those two tables point in opposite directions, and the disagreement is about what actually changes as a SaaS company grows. The agency ranges say spending intensity should be highest when you are smallest and fall as you grow. The survey says smaller companies spend less, and that marketing intensity rises toward the median rather than falling from a peak.

I do not think the agency numbers are invented. They are aspirational: what a well-funded company buying growth might spend. But they are published as descriptions of what companies do, and that is not what they are.

It is also worth saying plainly that I run an agency. The incentive runs the same way for me as for everyone else quoting the higher number, which is exactly why I would rather point you at a survey of a thousand companies than at my own opinion.

Funded companies spend twice what bootstrapped ones do

Here is the split that actually matters, and it is not the one the stage tables are built on.

Equity-backed B2B SaaS companies spend about 10% of ARR on marketing. Bootstrapped ones spend about 5%.

Twice as much, at the same revenue. That is not a benchmark difference, it is a strategy difference. A funded company is deliberately buying growth and market learning on somebody else’s money. A bootstrapped one is buying customers with its own.

If the benchmark you are copying came from a sample that does not match your funding position, it is the wrong benchmark no matter how well sourced it is.

#TCCRecommends: a benchmark is only useful if you can tell what your current spend produced. If you cannot, start with picking an attribution model that fits how you actually sell.

What should you base your SaaS marketing budget on instead?

Your CAC payback. A benchmark tells you what other companies spend. CAC payback tells you what you can afford to spend.

What CAC payback is

How many months of a customer’s revenue it takes to recover what you spent acquiring them.

Take your fully loaded acquisition cost for a period, divide by the customers you won, then divide by the gross monthly revenue each one brings. Spend $120,000 across marketing and sales in a quarter, win 20 customers, each paying $1,000 a month at 80% gross margin, and your payback is $6,000 divided by $800. Seven and a half months.

B2B SaaS CAC payback targets, and what yours is telling you

Segment	Target CAC payback
SMB	Under 12 months
Mid-market	Under 18 months
Enterprise	Under 24 months

Those targets are the point, because they tell you whether you can afford to spend more. That is the real question sitting underneath “what is the benchmark”.

Under 12 months. Spending more is usually right. You are turning money into customers faster than you are consuming it, and the constraint is how quickly you can deploy rather than whether you should.

Over 18 months. A bigger budget makes the hole deeper. You are not underspending. Something in the engine is leaking, and more fuel does not fix a leak.

Cannot calculate it. That is the finding, and no benchmark helps. Work out why the numbers are not available before you decide how much to spend.

#TCCRecommends: payback tells you how fast the money comes back. The companion number is how much comes back in total, which we covered in why SaaS brands fail at the LTV to CAC ratio.

What should a B2B SaaS marketing budget buy in 2027?

Worth knowing where other teams are moving money. From the 2026 State of B2B GTM report, across 300 companies, the areas seeing increased 2027 investment:

Area	Increasing investment
AI search and AEO	50%
Signal-based outbound	48%
Intimate events	42%
Founder and team LinkedIn posting	34%
Ecosystem partnerships	28%

Two things about that list make it harder to budget for than it looks.

AI visibility is the hardest thing on that list to measure. Half the teams surveyed are putting more money into it next year, and almost none of them can trace a closed deal back to it. We spent a month on ChatGPT Ads and the attribution was harder than the spend. Budget for the measurement alongside the work, or you will be asked what it bought and have nothing to show.

Most of that list is headcount, not ad spend. Events cost real money. The other four are mostly people’s time: writing, posting, researching accounts, building relationships. So if your budget conversation is mostly about where to buy ads, it is pointed at the one part of the list that is not growing.

#TCCRecommends: if AI search is where half your peers are putting next year’s money, the first job is working out whether you show up at all. We set out how in the AEO guide.

How to set your 2027 B2B SaaS marketing budget

Four steps, in order. The first one takes an afternoon and is the one most people skip.

Step 1: Find your baseline

Work out what you actually spent this year. Add up everything that went to marketing: salaries, contractors, agencies, tools, events, ads. Divide by this year’s ARR. Most B2B SaaS founders are surprised by the result, usually because the salaries were sitting in a payroll line nobody counted as marketing.

Step 2: Pick the right benchmark

Compare your baseline to the row that matches you, not the blended median. Among private B2B SaaS companies under $3M ARR, 5% is the median. Between $3M and $5M, 8% with 12% on selling. Bootstrapped sits toward the bottom of that, equity-backed at roughly double. Pick the row that describes your company rather than the one that describes your ambition.

Step 3: Run the payback check

Let CAC payback decide whether the number moves. Under 12 months, treat the benchmark as a floor and argue for more, because you are converting spend into customers faster than you are burning it. Over 18 months, hold the number flat and spend the year on conversion instead. If you cannot calculate payback at all, that is the thing to fix before the budget, not after.

Step 4: Allocate before you defend

Split the number before anyone asks you to justify it. Decide what the money buys, and remember that four of the five areas B2B SaaS teams are growing in 2027 are people’s time rather than media. A budget that is mostly ad spend will not survive its first review. A number with no plan behind it becomes four underfunded experiments and no way to tell which one deserved more. If you do not have that plan yet, start with the GTM strategy guide.

If your current spend is not producing, run the audit first. Building next year’s number on top of a leak is how companies end up having this conversation again in twelve months with bigger figures.

So what should your B2B SaaS marketing budget be?

Lower than the internet told you, most likely. If you were planning on 20% because a blog said so, you were about to spend two to three times what companies your size actually spend, and call it best practice.

But the benchmark is not really the answer either. It is a sanity check you run once, at the start, to find out whether you are wildly out of line. Then you put it away.

What decides your budget is your CAC payback, because it is the only number in this post that came out of your company rather than somebody else’s survey. Under 12 months, you can afford more than any benchmark suggests. Over 18, no benchmark is going to save you.

The founder with three tabs open was never short of benchmarks. They were short of a way to tell which one applied to them. That is an afternoon’s work, and it is the difference between a budget you can still defend in March and a number you picked because it was on somebody’s chart.
