SaaS Marketing Budget: What to Spend, and What to Hold It Against
Build the budget from the decisions you need made, then check it against a ratio — not the other way round. Below roughly €5 million of revenue, percentage-of-revenue rules are built from survey data about companies that do not resemble you, and one senior hire moves the number more than any allocation rule does.
The reason to distrust the published figures is not that they are approximate. It is that they disagree with themselves.
The numbers move faster than the advice does
We have been pulling Google's AI Overview on marketing-leadership cost queries weekly since late September. Here is what Google itself has told buyers about the price of the same job, in the space of three weeks.
| Date pulled | What Google's AI Overview said | Sources it attributed |
|---|---|---|
| 28 September 2026 | Fractional CMO services: $2,000 to over $22,000 per month; $200–$450/hour; $1,500–$3,500/day | Eight US firms, all of them sellers |
| 5 October 2026 | Full-time CMO salary $200,000–$350,000; fractional at 30–50% of a full-time executive's compensation | A fractional CMO firm and a talent platform |
| 19 October 2026 | Senior fractional leadership $4,000 to $17,000 per month; full-time total compensation "past $500,000–$650,000" | A talent marketplace and a staffing platform |
Google's own AI described a full-time CMO's cost as $200,000–$350,000 and then, fourteen days later, as reaching past $500,000–$650,000. Both figures came with confident framing. Neither has an independent survey behind it. The monthly fractional range has been quoted as $2,000–$22,000 and as $4,000–$17,000 in the same month.
Every one of those figures is sourced to a company that sells the service. We have now documented that mechanism in four markets this quarter, and this is the version of it that costs buyers real money: the price anchor you walk into a negotiation with was written by the other side.
The practical consequence is not "ignore benchmarks". It is: build the number bottom-up, then use a ratio as a sanity check, and treat any published range as a starting bid rather than a finding.
Build it from three questions
1. What marketing decisions need making this year, and who makes them? This is the leadership line, and it goes first because it determines whether the rest of the money is well spent. A company with budget and no direction reliably converts the budget into activity. When to hire a fractional CMO covers whether you are at that point; what a fractional CMO costs covers the figure itself.
2. Which channels can you actually run, as opposed to admire? Two run properly beat five run badly, and the constraint is almost never money — it is whether anyone can own each one. Budget the channels you have an owner for and leave the rest unfunded until you do.
3. What is the one number this spend will be judged on? Agree it before the money moves. Pipeline created, qualified conversations, activations — something countable in a quarter by someone who was not involved in producing it.
A fourth line that is small and routinely forgotten: the cost of finding out whether anything is working. Measurement tooling, and the occasional diagnostic. What an SEO or AEO audit costs sets out what that one looks like and when it is not worth buying.
How the split tends to go wrong
Channels first. The most common error. The budget is divided among the channels the team already knows, and the strategic question — whether those are the right channels — never gets funded because it has no line item.
Leadership last, or not at all. Treated as overhead rather than as the thing that decides whether the other 80% is spent well. At small numbers this is the single most expensive habit in the list.
Tooling as a proxy for capability. Software gets bought because it is easier to approve than a person, then nobody has time to operate it.
Everything added, nothing stopped. Budgets grow by accretion. A useful discipline: require that every new line names something it replaces, or explicitly accepts that it does not.
So what is the ratio actually for?
As a check, after the fact.
Published B2B figures commonly land in the high single digits to low teens as a share of revenue, and the spread around that is wide enough that the midpoint is not advice. Below about €5 million of revenue the ratio is close to meaningless anyway — a single senior hire can be several points of it, so the percentage tells you about your headcount decisions rather than about your marketing.
Where it earns its place is as a question rather than a target. If your bottom-up number lands far outside the range for companies your size, that is worth explaining. Sometimes the explanation is good — you are deliberately front-loading before a raise, or you have one channel that works and are pressing it. Sometimes the explanation is that nobody checked.
For what the money should be buying at each stage rather than what it should total, our go-to-market playbook is the longer version.
A worked shape, not a template
For a B2B SaaS company between first revenue and roughly €5 million, a budget that tends to survive contact with reality looks like this in order of decision rather than size:
- Leadership — someone senior accountable for allocation, whether that is a fractional CMO, a full-time hire, or a founder who has explicitly cleared the time for it. Agency, in-house or fractional is that decision.
- Two channels, properly resourced — with a named owner each.
- Content or creative capacity to feed them, which is where most of the hands-on money goes.
- Measurement — enough to answer the one number from question three.
- A reserve of roughly ten to fifteen per cent for the thing you will learn in month four. Budgets without slack get rewritten rather than followed.
Deliberately no percentages against those lines. Any split we published would be exactly the kind of unsourced benchmark this page is arguing against, and if you need the reserve line at twenty-five per cent because you are early, take it from the channels. If one pair of hands is not enough once direction is set, a fractional team instead of one person is the next increment.
Where Stefka fits
We publish our price, which is the smallest useful contribution anyone in this category can make to the problem above: engagements start at €5,000 a month. That number is a line in the leadership row, and it is meant to be held against the test from question three rather than against a benchmark.
We publish our own results too, including the unflattering ones — twenty-two ranking US keywords, three monthly organic visitors, and zero genuine AI mentions at the most recent measurement. Anyone quoting you a market rate should be willing to show you their own numbers alongside it.
Frequently Asked Questions
How much should a B2B SaaS company spend on marketing?
The percentage-of-revenue rules circulating online are built mostly from enterprise survey data and transfer badly below about €5 million of revenue, where the numbers are small enough that one hire dominates them. Below that, budget from the decisions you need made and the channels you can actually run, not from a ratio.
What percentage of revenue should go to marketing?
Published B2B figures commonly sit in the high single digits to low teens, and the spread is wide enough that the midpoint is not advice. The number is more useful as a check on a budget you built from the bottom up than as a way to build one.
How should an early-stage marketing budget be split?
The most useful split is leadership, channels and tooling, in that order of decision. Decide what proportion buys judgement first, because that decision determines whether the rest is spent well. Teams that allocate channels first tend to fund whatever they already know how to do.
What does marketing leadership cost inside that budget?
Google's AI currently quotes $4,000 to $17,000 a month for senior fractional leadership, sourced to two talent marketplaces, against full-time compensation it has described as both $200,000-$350,000 and past $500,000-$650,000 within a fortnight. Treat all published figures here as marketing collateral rather than data.
What should a marketing budget be held against?
One number you agree in advance and can measure in a quarter — pipeline created, qualified conversations, or activations. Not impressions, not rankings, not a score out of 100. If nobody can name the number before the money is spent, the budget has no test attached and will be judged on feeling.
Building the number from the bottom up?
Stefka publishes its price — engagements start at €5,000 a month — so the leadership line in your budget has a real figure in it rather than a supplier-written range. Held against your one number, not a benchmark.
