What Is a Marketing Budget?
A marketing budget is the amount of money a business sets aside, over a defined period, to plan, produce and run its marketing activity. It covers everything from paid advertising and content production to website costs, brand work, tools and the people who do the work, whether that’s an in-house team or an external agency.
At its simplest, a marketing budget answers two questions: how much are we spending, and what are we spending it on. Get those two answers right and you have a plan you can defend to a finance director, a board, or your own bank balance. Get them wrong and marketing becomes the first line item cut when things get tight, because nobody can explain what it actually bought.
A marketing budget isn’t a wish list. It’s a working document that sits inside your wider marketing plan budget and, ultimately, your business’s profit and loss. If it doesn’t connect to revenue, retention, or pipeline, it’s not doing its job.
Why Your Marketing Budget Matters More Than the Number Itself
Most businesses fixate on the top-line figure: is £20,000 enough, should it be £50,000, what does a competitor spend. The number matters, but it’s not the part that determines whether marketing works.
What matters more is allocation: how that figure is split across channels, activities and timeframes, and whether the split matches what the business actually needs right now. A £30,000 budget spent well, against a clear plan and clear targets, will consistently outperform a £100,000 budget spread thinly across a dozen channels with no priority order.
This is where a marketing budget earns its keep as a planning tool rather than a spreadsheet exercise. It forces decisions: which channels get funded first, which get tested with a small amount before scaling, and which get dropped because they’re not earning their place. Those decisions are far easier to make with a proper profit and loss template sitting alongside the budget, so marketing spend is always viewed in the context of margin, not in isolation.
It’s the same discipline we build into every fractional engagement we run — the allocation gets set and reviewed alongside the client’s actual P&L, not in a marketing-only spreadsheet nobody else in the business ever sees.
What Should Be Included in a Marketing Plan Budget?
A comprehensive marketing plan budget usually covers seven areas. Not every business needs to fund all seven at once, but each should at least be considered and consciously included or excluded.
Paid media and advertising
Search ads, social ads, display, sponsorships and any other pay-to-play channel. This is usually the most flexible part of the budget, because spend can be scaled up or down monthly based on performance.
Content and creative production
Copywriting, photography, video, design assets and the editorial calendar that supports organic channels. Content underpins almost every other line item, from ads to social to the website itself.
SEO and organic growth
Technical SEO, on-page optimisation, link building and ongoing content strategy aimed at ranking in search rather than paying for clicks. Organic growth is slower to build than paid media but tends to be far cheaper to sustain once it’s working. Our SEO guide for businesses covers what this looks like in practice, and our roundup of SEO tools is worth reviewing before you commit budget to any single platform.
Website and technology
Hosting, website builds and redesigns, landing pages, CRM and marketing automation platforms all sit here, alongside the ongoing cost of maintaining and updating a site once it’s live. A good site is the foundation everything else points back to; ads, social and email all eventually route someone back to a page that has to convert. See our complete guide to website design for what’s reasonable to budget for a rebuild versus ongoing maintenance.
Brand and design
Brand identity, guidelines, messaging frameworks and the design work that keeps everything consistent across channels. This is often treated as a one-off cost, but a strong brand foundation, as covered in our brand strategy guide, reduces creative costs elsewhere because every future asset has a clear starting point.
Tools, software and reporting
Analytics platforms, project management tools, email marketing software and design subscriptions. Individually small, collectively these commonly add up to somewhere in the 5-10% range of a marketing budget — worth naming as its own line rather than absorbing into “software” on the general P&L, since it’s easy to lose track of what’s actually being paid for across a dozen small subscriptions.
People and agency costs
In-house salaries, freelancer fees, or agency retainers. For many small and mid-sized businesses, this is the single largest line item, and the one most worth scrutinising for value rather than just cost.
How Much Should You Spend? Marketing Budget Allocation by Business Stage
There’s no single correct percentage, and any article that gives you one number without context is oversimplifying. Marketing budget allocation should reflect the stage your business is at.
Early-stage and startup businesses typically need to spend aggressively to build awareness from a standing start. A budget of 15-30% of projected revenue is common at this stage, since the cost of acquiring each new customer is naturally higher before word-of-mouth and repeat business kick in. Not every early-stage business needs a large budget to make progress; Forbes has a good breakdown of how new businesses can earn attention without a big marketing budget, particularly through organic and community-led channels.
Growth-stage businesses, those scaling a proven model, generally sit in the 10-15% range. The priority shifts from pure awareness to a mix of acquisition and retention, with more budget flowing into content, SEO and CRM as the customer base grows.
Established, stable businesses protecting an existing market position can often operate on 2-10% of revenue, since brand recognition and repeat custom do some of the work that paid acquisition would otherwise need to do.
These ranges are a starting point, not a rule. Forbes’ practical guide to determining your perfect marketing budget makes the same point: the right figure depends on your goals, your margins and how competitive your market is, not on a benchmark pulled from a different industry.
How to Set a Marketing Budget: A Step-by-Step Approach
- Start with your revenue goal, not your marketing wish list. Work backwards from what the business needs to achieve this year, then ask what marketing needs to contribute to get there.
- Review last year’s spend and results. If you don’t have this yet, start tracking now. You can’t improve a marketing budget allocation you’ve never measured.
- Choose your percentage range based on business stage, using the ranges above as a guide rather than a target.
- Break the total down by channel, using the seven categories outlined earlier. Be specific: don’t leave “social media” as a single line if it covers both paid ads and organic content, since they behave very differently.

Work out your split in minutes, not spreadsheets
Our Marketing Budget Calculator does the allocation above automatically — enter your revenue and business stage and it splits the total across all seven categories for you.
- Build in a testing allowance. Set aside 10-15% of the total budget for trialling a new channel or format without disrupting what’s already working.
- Map the budget against your P&L, quarter by quarter, so spend is visible against actual revenue rather than sitting in a separate spreadsheet nobody else looks at.
- Review quarterly, not annually. A marketing budget set in January and left untouched until December has usually stopped reflecting reality by March.
Marketing Budget Example
To make this concrete, here’s a marketing budget example for a business with £1.5 million annual revenue, aiming for moderate growth and allocating 10% of revenue to marketing, a total budget of £150,000 for the year.
- Paid media and advertising: £45,000 (30%)
- SEO and organic growth: £30,000 (20%)
- Content and creative production: £24,000 (16%)
- Website and technology: £18,000 (12%)
- People and agency costs: £18,000 (12%)
- Tools, software and reporting: £9,000 (6%)
- Brand and design: £6,000 (4%)
The exact split will look different for a service business versus a product business, or a B2B company versus a consumer brand. The point of the example isn’t the specific figures; it’s the discipline of assigning every pound to a named category before the year starts, rather than spending reactively and categorising it afterwards.
Common Mistakes When Setting a Marketing Budget
Copying a competitor’s spend without knowing their goals.
A larger competitor spending more doesn’t tell you anything about what they’re spending it on, what their margins allow, or whether it’s actually working for them. It tells you a number, and not much else.
Treating the budget as fixed once it’s set.
Markets shift, campaigns underperform, and a channel that was cheap in January can double in cost by June. A budget that can’t flex quarterly isn’t a plan, it’s a guess with a deadline.
No line item for measurement.
Plenty of businesses will fund the campaign but not the analytics, reporting, or attribution work needed to know whether the campaign did anything. Without that, next year’s budget is set exactly the same way this year’s was, on instinct.
Cutting marketing first when revenue dips.
It’s the easiest line to cut because the effects aren’t immediate, which is precisely why it’s often the wrong call. Our view: a business that keeps spending through a downturn, even at a reduced level, protects the visibility and market presence it’s already paid to build — where a business that stops entirely usually has to rebuild that visibility from zero once conditions improve, at a higher cost than staying present would have been.
Overweighting new customer acquisition and ignoring retention.
Acquisition costs are usually the highest cost per pound of return, yet many budgets allocate almost nothing to retaining the customers already on the books. In our experience, a modest CRM or lifecycle email spend is one of the cheapest lines in the whole budget to justify, precisely because it’s working on customers who’ve already been paid for once.
Setting the budget in isolation from finance.
Marketing budgets built without reference to gross margin or cash flow timing tend to get approved once and questioned every month after. Building the budget alongside a proper P&L view from the outset avoids most of this friction later.
Reviewing and Adjusting Your Marketing Budget
A marketing budget is only as good as the discipline behind reviewing it. Set a quarterly checkpoint and ask three questions each time: what did we spend against plan, what did that spend actually produce, and does the next quarter’s allocation still make sense given the answer to the first two.
Where a channel is outperforming, move budget towards it before the quarter ends, not at the next annual planning cycle. Where a channel is underperforming despite reasonable time to prove itself, cut it and reallocate rather than letting it run on inertia because it’s already in the spreadsheet.
The businesses that get the most from a fixed marketing budget aren’t the ones with the biggest number; they’re the ones willing to move money within the number as evidence comes in.
