Planning a marketing budget is rarely a pure arithmetic exercise. In the end the numbers are the result of assumptions, priorities and trust. Anyone who wants to plan and defend a marketing budget therefore needs less a perfect spreadsheet than a clear explanation of why this money achieves the most exactly here.
The question matters more than many planning rounds treat it. In difficult years marketing counts as the cost block where savings come fastest. When the justification is missing, budgets get cut, and often exactly where the effect is long-term and therefore hard to show. A well-justified budget protects not only marketing but the brand.
- A marketing budget is a strategic promise, not a pure arithmetic exercise.
- Planning from objectives and tasks convinces more than rolling forward last year’s figures.
- Brand investment and short-term activation need different justifications.
- You defend a budget throughout the year, not only in the budget round.
- Openly named assumptions make the plan more credible.

What a marketing budget really is
In business terms the matter is clear. Advertising costs cover all spending on advertising and the presentation of products, including the planning and production of advertising materials, and the advertising budget brings them together for one financial year. This definition is useful because it is a reminder that media costs are not the only thing that counts. Production, agency services, tools and internal capacity belong in it too, even if they are often hidden in other cost centres.
For me, though, a marketing budget is above all a promise. It translates the company’s goals into a statement about what marketing intends to achieve with which resources. That makes it a strategic document and not just a financial instrument. Whoever sees it this way asks different questions in planning: not only how much money is available, but what it is supposed to change.
The familiar budgeting methods all have their place. You can start from revenue, take your cue from the competition, or calculate from objectives and tasks. In practice I have seen that the first method is used most often and the last convinces most. Planning from tasks means saying what is to be achieved and what that requires. It is more laborious, but it is the only justification that holds up under critical questioning.
I also care about the distinction between investment in the brand and spending on short-term activation. Both are necessary. But they work on different time axes and therefore need different justifications. Even so, brand or performance is the wrong question for me. The point is not to play one off against the other, but the ratio between the two. Activation without brand becomes more expensive over time, brand without activation remains without visible return.
Where marketing budget planning fails in practice
The most common mistake is rolling the marketing budget forward. Last year’s budget is taken, adjusted by a percentage and redistributed. That saves time but prevents any real prioritisation. Whatever is in the budget once stays there, even when it has long stopped working.
The second mistake is the missing link to company goals. A marketing budget that consists only of channels and activities is hard to defend, because nobody outside marketing understands what is at stake. If instead it becomes clear which contribution to revenue, customer acquisition or brand strength is expected from which item, the discussion changes.
I experienced this link particularly clearly at the department store Breuninger. There I had full budget and P&L responsibility for marketing, content and production and reported at board level. In those meetings, which channels were used mattered less than the question of what contribution an item makes to the business and how you can tell. What I took away was to justify every larger budget block so that it is understandable without marketing vocabulary. That did not make the conversations easier, but it made them much more honest.
Fashion adds a particular difficulty. Planning follows the seasons, but the effect of brand work does not. Cutting brand investment in a weak season often shows its consequences only later, when the connection is hardly visible any more. I have often seen this very delay lead to cuts being regarded as having no consequences.
The third mistake is a lack of flexibility. A marketing budget that is planned down to the last euro at the start of the year leaves no room for opportunities and no response to change. I consider a deliberately unallocated share sensible, to be decided on during the year. This leeway is not a sign of poor planning but an admission that nobody can foresee everything at the start of the year. What matters is to define beforehand by which criteria it will be decided.
What this means for a brand
You do not defend a marketing budget in the budget round but throughout the year. What matters is that marketing shows regularly and transparently what happens with the money. That includes a few well-chosen metrics that measure not just activity but effect.
For long-term brand work, however, short-term metrics are not enough. It needs its own language towards management and boards. I have had good experiences presenting brand strength as a value of its own that grows or shrinks over time, as I describe in the article on brand equity reporting. This makes visible that a cut is not just a saving but also a loss.
Methods such as marketing mix modeling can help to understand the effect of individual channels better. But they do not replace judgement. No model alone can decide how much a brand should invest in its future. That decision remains a question of strategy and courage.
For a brand, a well-justified budget means above all continuity. Brands are built through repetition over long periods. A budget that is fundamentally questioned every year prevents exactly this continuity. Anyone who wants to build a brand has to give it time. That only works if the budget has a reliable base above which the flexible parts may change.
What I would do differently with the next marketing budget
I would talk to the finance department earlier, not only once the numbers are fixed. The best budget conversations I have experienced were not negotiations but joint reflections on where the company wants to grow and what marketing can contribute. Whoever understands the logic of the finance side can phrase their own arguments in its language.
I would also deliberately set part of the budget to zero every year and have it justified anew. Not the whole budget, that would be too laborious. But an area that has not been questioned for a long time deserves this review.
And I would separate more clearly between what I know and what I assume. A budget always rests on assumptions about effect. Naming them openly does not make it weaker but more credible. Whoever admits where uncertainty exists and shows how they intend to reduce it during the year is more convincing than someone who pretends to be certain.
I remain unsure how much brand investment a company should maintain in a crisis. The arguments for continuity are strong. But there are situations in which liquidity takes priority. I believe this trade-off cannot be made in marketing alone, only together with management, and that the quality of the decision depends on how well those involved have talked to each other beforehand.
