Marketing spend as a percentage of revenue varies with company stage, gross margin, sales model, and growth rate, so no “X% for every business” rule is defensible. Gartner reported an average of 7.7% of revenue among large enterprises in its 2025 survey. The Spring 2026 CMO Survey reported 9.0%. Those figures are useful reference points, not targets: the samples and budget definitions differ. The right investment should come from serviceable demand, customer acquisition cost, contribution margin, payback, cash constraints, and the number of customers the business can successfully absorb.
TL;DR
- There is no universal correct percentage. Two current large surveys report averages of 7.7% and 9.0% of revenue, but use different samples and definitions.
- The percentage is an output, not an input. Set the budget bottom-up from CAC, payback and growth targets, then check it against benchmarks — not the other way round.
- Stage moves it more than industry. Early, high-growth companies spend a far higher share than mature ones; growth ambition is the biggest lever.
- B2C and consumer brands spend more of revenue than B2B, which invests heavily in sales headcount instead.
- Split new-business from maintenance spend. Growth requires more than holding a position does.
- Top-down percentages cause two failures: underfunding growth in a good market, and overspending against a shrinking one.
- Marketing spend is an investment decision, judged on return, not a fixed cost line to minimise.
Why the percentage is the wrong place to start
The question "what percentage of revenue should we spend on marketing?" feels precise, but it inverts the logic. It treats marketing spend as a fixed proportion to be set top-down, when spend should be derived from what the business is trying to achieve and what acquisition actually costs.
Consider two companies with identical revenue. One has a CAC payback of four months and a large addressable market; every additional euro of marketing returns quickly and there is room to grow. The other has a payback of two years and a saturated market; extra spend returns slowly, if at all. A single "12% of revenue" rule would badly underfund the first and dangerously overspend the second. The right budget is different because the economics are different — and the percentage each ends up at is a result of those economics, not a rule either followed.
This is why the strongest budgeting starts bottom-up: how many customers do we want to add, what does each cost to acquire, how fast does that cost pay back, and how much can we afford to invest given that payback and our cash position. The percentage of revenue falls out of that calculation. Benchmarks then serve as a sanity check: if the bottom-up number is wildly outside the typical range for your stage and model, that is a prompt to re-examine assumptions.
What 2025 and 2026 marketing budget benchmarks say
Current benchmarks require context before they can support a decision:
- Gartner CMO Spend Survey 2025: 7.7% of company revenue. The survey covered 402 marketing leaders in North America, the United Kingdom, and Europe. Most respondents represented companies with more than $1 billion in annual revenue, making this primarily a large-enterprise benchmark.
- The CMO Survey, Spring 2026: 9.0% of company revenue and 9.6% of total company budget. Duke University's long-running survey, supported by Deloitte and the American Marketing Association, reports the average across its respondent mix.
The difference between 7.7% and 9.0% does not make either result wrong. Company size, industry mix, survey timing, and the definition of “marketing” all change the average. The figures are directional reference points for established organizations, not a prescription for a seed-stage SaaS company, regional law firm, or direct-to-consumer brand.
The directional factors remain useful:
| Factor | Higher share of revenue | Lower share of revenue |
|---|---|---|
| Stage | Early / high-growth | Mature / stable |
| Model | B2C, consumer brands, DTC | B2B (spends on sales headcount instead) |
| Growth ambition | Aggressive expansion | Defending position |
| Margin | High-margin (can fund more) | Low-margin (less to fund with) |
| Category | New / competitive category | Established / low-competition |
A high-growth B2C company and a mature B2B company can legitimately differ by several multiples in marketing-to-revenue ratio. Sales motion, margin, new-customer targets, and the treatment of payroll and technology often explain more than the industry label alone.
Define what counts as marketing spend
A benchmark is meaningless when the numerator is inconsistent. A board-ready budget needs a stable cost taxonomy. It will usually include:
- paid media, sponsorships, and marketplace promotion;
- marketing-team compensation and employer costs;
- agencies, contractors, and specialist advisors;
- creative, video, content, and landing-page production;
- software, data, analytics, and marketing automation;
- events, sales collateral, PR, research, and brand tracking;
- discounts or promotions only when the company consistently classifies them as marketing.
Sales compensation, cost of goods sold, customer onboarding, and trade discounts should be shown separately. This distinction matters most in B2B: a low marketing-to-revenue ratio may simply mean acquisition cost sits in account executives and sales development. Boards should therefore monitor both marketing spend / revenue and total go-to-market spend / revenue.
For international groups, currency translation and tax treatment also need a written rule. US budgets may be presented net of sales tax because it is generally collected at the transaction level, while UK and EU entities need a consistent treatment of recoverable VAT. The point is comparability, not one universal accounting presentation.
Stage moves the number more than anything
The single biggest driver of marketing-to-revenue ratio is where the company is in its life. An early-stage company chasing growth spends a high share of a small revenue base, deliberately running "inefficiently" by mature standards because it is buying market position and future revenue. A mature company defending a strong position spends a lower share, because it is maintaining rather than expanding.
This is why comparing your ratio to an industry average without controlling for stage is misleading. A startup benchmarked against mature-company averages will look like it is overspending when it is correctly investing in growth; a mature company benchmarked against startups will look frugal when it is under-investing and ceding ground. Match the benchmark to your stage and growth ambition, or the comparison misleads more than it helps.
Split growth spend from maintenance spend
A useful discipline is to separate the budget into two jobs, because they have different return profiles:
- Maintenance spend holds the current position — brand presence, retention, existing-demand capture. It should return reliably and roughly track revenue.
- Growth spend buys new customers and market share. It is an investment with a payback period, judged on CAC and payback, and it is the part that scales up or down with ambition and cash.
Blending them into one percentage hides the decision that matters. A leadership team can hold maintenance steady while flexing growth spend up in a good market or down in a tight one — a far more precise lever than moving a single blended percentage. This mirrors the bottom-up logic in how to plan a marketing budget and depends on knowing your customer acquisition cost and payback.
Build the budget from unit economics
A practical bottom-up model has five steps:
- Set the target for new customers or qualified opportunities. Account for retention and churn so gross additions do not masquerade as net growth.
- Estimate fully loaded CAC by segment and channel. Include media, creative, tools, agency cost, and the appropriate share of payroll.
- Test contribution margin and payback. Revenue does not repay CAC; customer contribution does.
- Add the cost of maintaining brand, retention, and the current demand base. Not every necessary investment can be assigned to one acquisition.
- Apply operating and cash constraints. Marketing should not create more orders or opportunities than sales, inventory, onboarding, or support can absorb.
For example, a target of 300 new customers at a fully loaded CAC of $1,500 implies $450,000 of acquisition spend. If brand maintenance, the team, and core infrastructure require another $300,000, the annual marketing budget is $750,000. Against $10 million in planned revenue, that equals 7.5%. Only then should 7.5% be compared with a survey average and the assumptions behind CAC, margin, and capacity challenged.
Set rules for releasing and reducing budget
A strong platform ROAS is not enough to release more budget. Four conditions should hold: customer quality remains stable, marginal payback is acceptable, the business has delivery capacity, and serviceable demand remains. Every test also needs a predefined stop-loss, maximum exposure, and review date.
Budget should contract when marginal CAC moves beyond the approved threshold, customer quality deteriorates, or operations cannot absorb demand. A temporary attribution lag should not be treated as structural deterioration. Decision windows need to reflect the sales cycle, conversion delay, and refund or cancellation behavior.
This turns the annual budget into governed investment tranches. Finance retains downside control, while marketing can scale without waiting for the next planning cycle whenever the agreed evidence is present.
Glossary
- Marketing-to-revenue ratio — total marketing spend as a percentage of revenue.
- Bottom-up budgeting — deriving spend from growth targets, CAC and payback rather than a top-down percentage.
- Maintenance spend — budget that holds the current position (brand, retention, existing demand).
- Growth spend — budget that acquires new customers and share, judged on payback.
- CAC payback — months for a customer's gross-margin revenue to repay acquisition cost.
- Share of voice — a brand's marketing presence relative to competitors, a driver of long-term share.
The two ways a top-down percentage fails
Setting the budget as a fixed percentage of revenue creates two predictable failures, in opposite directions.
Underfunding growth in a good market. When revenue is growing and payback is fast, a fixed percentage caps spend below what the economics justify — leaving profitable growth unbought because the "budget" ran out. The right response to efficient, fast-paying acquisition is usually to spend more, not to stop at an arbitrary line.
Overspending against a shrinking one. When revenue falls, a percentage-of-revenue budget falls with it — often exactly when the business most needs to defend its position, and sometimes cutting the growth spend that would recover it. Conversely, a percentage that does not flex can keep spending into a market where returns have collapsed.
Both failures come from treating the percentage as the decision. The decision is how much to invest given the return available; the percentage is what that investment happens to equal this year.
How Space Ads approaches the marketing budget
We begin with a precise business outcome and its fully loaded acquisition cost. Platform spend, production, agency cost, and CRM outcomes are joined before new and returning customers are separated. Growth budget then comes from the target, CAC, contribution margin, and payback; brand maintenance, team, and infrastructure stay visible as separate lines. We also test constraints an ad dashboard cannot see: sales capacity, inventory, onboarding time, service delivery, and the cash needed to finance payback. The percentage benchmark is used only after the model produces a number. Pre-agreed thresholds govern when budget can increase, pause, or return for review, so allocation does not depend on one strong week or an arbitrary annual cap. This connects web analytics, performance marketing, and fractional CMO leadership to the economics of the whole company.

| Treating marketing as a fixed cost to minimise | Treat it as an investment judged on return |
FAQ
What percentage of revenue should a company spend on marketing?
There is no universal figure. Broad surveys typically place marketing budgets in the range of roughly 5–15% of revenue, but the spread is enormous: high-growth, B2C and consumer brands sit higher, mature and sales-led B2B companies lower. The right number is derived from your CAC, payback and growth targets, then checked against benchmarks for your stage.
Is a marketing budget an input or an output?
It should be an output. Set it bottom-up from how many customers you want to add, what each costs to acquire, and how fast that cost pays back — then the percentage of revenue falls out of that calculation. Treating a top-down percentage as the input causes underfunding of growth or overspending against a decline.
Why do B2C companies spend more of revenue on marketing than B2B?
B2C and consumer brands rely on marketing to create demand at scale, so a larger share of revenue goes to marketing. B2B companies typically invest heavily in sales headcount to close considered, high-value deals, so their marketing-to-revenue ratio is lower while total go-to-market spend can be comparable.
How does company stage affect the marketing budget?
Stage is the biggest driver. Early, high-growth companies deliberately spend a high share of a small revenue base to buy market position and future revenue; mature companies spend a lower share to maintain position. Comparing a startup's ratio to mature-company averages misleads in both directions.
Should you cut the marketing budget when revenue falls?
Not automatically. A percentage-of-revenue budget falls with revenue, often when the business most needs to defend its position. The better approach separates maintenance spend from growth spend, so leadership can protect what defends and recovers the business rather than cutting the spend that would help it recover.
How do you benchmark a marketing budget correctly?
Match the benchmark to your stage, business model and growth ambition, use it as a sanity check on a bottom-up number rather than as the target, and separate growth from maintenance spend. Sources like the Gartner CMO Spend Survey and the Deloitte CMO Survey give directional ranges, not prescriptions.

Marketing ROI: How to Model It So Finance Actually Believes It
Marketing ROI claims usually fail the finance test because they rest on platform-reported revenue, ignore margin, and skip the time lag. A model finance believes is built on incremental, gross-margin revenue, honest about attribution, and expressed in payback and efficiency terms a CFO already uses.
How to Build a B2B Marketing Budget That Survives the CFO
A B2B marketing budget survives CFO scrutiny when it is built around pipeline and revenue, not activities. Tie every line to a pipeline or payback logic, separate demand creation from capture, and give the CFO the numbers they think in — coverage, CAC, payback — so marketing is the last thing cut, not the first.
MER vs ROAS: The Blended Metric Your Board Should Actually Track
Platform ROAS overstates return because every channel claims the same conversions. MER — total revenue divided by total marketing spend — is the blended, un-gameable number a board should track, with ROAS kept for channel-level optimisation, not for judging whether marketing pays.
