Marketing Budget: How Much to Spend, How to Set It and How to Split It by Channel

A marketing budget answers two questions at once: how much the company can afford to invest in growth, and where each euro or dollar produces the most customers. The figures in this guide come from two primary surveys: the Gartner 2026 CMO Spend Survey (401 marketing leaders, mostly at companies above $1 billion in revenue, published May 2026) and the The CMO Survey 2026 run by Duke University, Deloitte and the American Marketing Association (308 US marketing leaders, January 2026).

What does a marketing budget include?

A complete marketing budget covers every cost needed to attract, convert and retain customers, not only advertising. Forgetting a line is the most common reason budgets are exceeded in the second half of the year.

• Paid media: Google Ads, Microsoft Ads, Meta, LinkedIn, TikTok, sponsorships, display.
• Content and SEO: articles, landing pages, videos, design, link acquisition, SEO software.
• Tools: CRM, email platform, analytics, automation, AI subscriptions.
• People: salaries of the marketing team, freelancers, agencies.
• Events and brand: trade shows, print, merchandise, rebranding projects.
• Retention: loyalty programs, customer marketing, referral rewards.
• Contingency: a reserve of 5 - 10% for tests and opportunities.

An advertising budget is only one part of this list. Whether salaries are included changes the benchmark completely, so always check what a published percentage covers before comparing yourself to it.

How much should a company spend on marketing?

There is no universal figure, but published surveys give a reliable range. The average marketing budget sits between 7% and 10% of revenue, with a wide spread around it.

The gap between the mean (8.96%) and the median (5%) in The CMO Survey shows that a few heavy spenders pull the average up: half of the companies spend 5% of revenue or less. Gartner also reports that 56% of CMOs say they lack the budget to deliver their 2026 strategy, and that marketing teams now put 15.3% of their budget into AI initiatives.

Three factors move a company above or below these averages:

1. Growth stage: a young company that needs to win market share spends a larger share of a smaller revenue; a mature company protects its position with a lower share.
2. Business model: software, consumer brands and e-commerce usually spend more than industrial B2B companies, where sales teams carry most of the acquisition.
3. Gross margin: a high margin leaves more room to buy customers; a low margin forces a stricter cost per acquisition.

How do you set a marketing budget? The four methods

Most companies combine two methods: a top-down percentage to frame the total, and a bottom-up calculation to check it can reach the goals.

1. Percentage of revenue

Take last year's revenue (or next year's forecast) and apply a percentage, usually between 5% and 10%. It is simple and easy to defend in front of finance, but it links marketing to past results: when sales drop, the budget drops exactly when you need demand.

2. Objective and task

Start from the goal and work backwards. Example: 400 new customers next year, a close rate of 20% on qualified leads, so 2,000 leads; at a cost per lead of $60, the acquisition budget is $120,000, plus tools and content. This method ties every dollar to an outcome, and the customer acquisition cost calculator gives you the starting figure.

3. Competitive parity

Estimate what competitors spend (visible ads, content volume, events) and match or exceed it on the channels where you want share of voice. Useful as a check, risky as the only method, because competitors may have different margins and goals.

4. Unit economics (LTV to CAC)

Decide the maximum you can pay for a customer from their lifetime value. A common rule of thumb in software is a lifetime value at least three times the acquisition cost. Check your own figures with the LTV to CAC ratio calculator, then multiply the acceptable cost per customer by the number of customers you want.

How should you split a marketing budget by channel?

The split depends on how fast you need results and how long you can wait for them. Paid media buys immediate traffic that stops when spending stops; SEO, content and GEO take months to start but keep producing leads without a cost per click. Define the balance with your marketing mix and write it into your marketing plan.

The table below is a starting split for a company spending $10,000 a month on acquisition (people excluded). It is an example to adapt, not a benchmark.

Two rules keep the split healthy. First, fund each channel enough to be measurable: $300 a month spread over five ad networks teaches you nothing. Second, review the allocation every quarter and move money towards the channels with the best cost per customer, using the ROAS calculator for paid campaigns. On Google Ads, remember that you set an average daily budget: Google can spend up to twice that amount on a given day, within a monthly cap of 30.4 times the daily budget, as explained in its help page on average daily budgets. Our guide to Google Ads costs details typical cost per click by sector.

How much of the budget should go to SEO and GEO?

SEO and GEO (generative engine optimization, being cited by ChatGPT, Gemini, Claude and Perplexity) are the channels whose returns accumulate: an article that ranks in month four still brings visitors in month twenty, without paying for each click. Their weakness is the delay, which is why budgets that are cut each quarter rarely give them time to work.

• Company with no organic traffic: start with 15 - 25% of the acquisition budget on content and SEO while paid media brings early customers.
• Company with established rankings: 25 - 40% to defend positions, refresh content and cover new questions asked to AI assistants.
• Company dependent on paid ads: shift a few points each quarter from ads to SEO and track the cost per customer of each channel.

To size this line, the SEO budget calculator estimates a monthly amount from your goals, and the SEO break-even calculator shows how many months it takes for organic traffic to pay back its cost. Our article on SEO cost compares agency, freelance and software prices.

GEO deserves its own line in 2026. The CMO Survey 2026 found that 41.5% of companies using AI in marketing already use it to appear in AI-generated search results. Being cited depends on sources that AI assistants trust, and our study of AI citations in the marketing sector shows which types of pages they pick.

How do you build a marketing budget on a small budget?

With a few hundred or a few thousand a month, concentration beats coverage. The methods in our guide to small business marketing follow the same logic:

1. Pick one acquisition channel and one retention channel, for example search ads plus email, or SEO plus email, and master them before adding a third.
2. Spend first on what you own: your website, your content and your email list keep their value when you stop paying.
3. Automate production: software now does work that used to need an agency, such as keyword research, writing and publishing articles. An automated blog article generator costs less per month than a single agency article.
4. Earn authority instead of buying it: backlinks remain a ranking signal for Google and a trust signal for AI assistants. Sorank obtains natural backlinks automatically from its network of 5,000+ users, through its backlink acquisition feature.
5. Measure from day one: UTM tags, a conversion goal in your analytics tool and a monthly review of cost per customer by channel.

How do you track and adjust a marketing budget?

A budget is a forecast; tracking turns it into a management tool. Keep a simple spreadsheet with one line per channel and four columns: planned, actual, leads or sales generated, cost per result. Then follow this rhythm:

• Monthly: compare actual spend to plan, pause campaigns whose cost per result exceeds your ceiling.
• Quarterly: reallocate 10 - 20% of the budget towards the best channels, renew the reserve for tests.
• Yearly: rebuild the budget from goals, not from last year's figures plus inflation.

Judge long-term channels on the right horizon: a content program measured after six weeks always looks worse than paid ads. Align the review with your content marketing strategy so that content is judged on traffic, leads and citations after six to twelve months.

The essentials

Start from a percentage of revenue (5% to 10% covers most companies), check it against your goals and your acceptable cost per customer, and split it between channels that bring results now and channels that compound. The healthiest marketing budget funds paid media for this quarter and SEO and GEO for the next ones.
