How much should an event organiser spend on advertising?
It is tempting to answer with a percentage of expected ticket revenue: perhaps 10%, 15%, or whatever was spent on the previous event. But there is no universal percentage that makes sense for every event. A new festival, a specialist conference and an established theatre production can have completely different advertising economics even if their ticket prices are similar.
The smarter way to approach the question is to start somewhere else: how much is an additional customer actually worth to the event?
That question turns advertising from a vague marketing expense into a commercial decision.
The Ticket Price Is Not the Advertising Budget
Suppose a ticket costs £60. That does not mean the organiser can afford to spend £60 to acquire a customer.
Ticket revenue has to be considered alongside the costs of delivering the event. Venue and production costs, staffing, ticketing and payment costs, taxes, marketing and other expenses all affect how much contribution a new ticket sale actually creates.
This is why customer acquisition cost (CAC) is useful. If an organiser spends £6,000 on advertising and generates 300 attributable purchases, the advertising cost per purchase is £20. Whether £20 is good or bad depends on the economics behind those purchases.
An event with strong margins and customers who regularly buy multiple tickets may be able to support a higher acquisition cost than an event where customers buy one low-margin ticket and never return.
So the important question is not simply “What does a ticket cost?”. It is “How much can we reasonably spend to generate an additional sale and still achieve the financial objective of the event?”
Existing Demand Changes Everything
Advertising does not have the same job for every event.
An established event may already have an audience of previous attendees, email subscribers, social followers and people who actively search for it. In that situation, paid advertising may mainly help capture and convert existing demand.
A new event has a much harder task. Before people can buy a ticket, they first have to discover the event, understand why it is relevant and become sufficiently interested to consider attending.
That difference can have a major effect on the advertising budget.
An organiser should therefore estimate how many tickets are likely to be sold through existing channels and how many additional sales actually need to come from paid marketing.
If organic demand is expected to generate most of the required attendance, there may be little reason to spend aggressively simply because a larger budget is available.
The Most Important Number May Be the Next Customer
Imagine an event needs another 1,000 ticket sales to reach its target.
If advertising can consistently generate those customers at an economically sustainable cost, increasing the budget may make sense.
But that does not mean the campaign can be scaled indefinitely.
The first £5,000 may reach highly relevant audiences who are already interested in the event. The next £5,000 may reach people who are less familiar with the organiser. The next £5,000 after that may have to work even harder to find customers who are willing to buy.
As advertising expands, marginal returns can decline.
This is why the most interesting budgeting question is not the average performance of the campaign. It is what happens when the organiser spends the next pound.
If the next pound produces valuable additional sales, there may be room to scale. If it produces increasingly expensive customers, the campaign may already be approaching its practical limit.
Advertising Should Be Timed Around the Buying Decision
There is also no reason to assume that an advertising budget should be spent evenly from the first day of promotion until the event.
Some events require a long period of awareness-building. A large conference may need to give potential attendees time to secure budgets, arrange travel and obtain approval to attend. Other events can generate much of their demand closer to the event date because the decision is more spontaneous.
The advertising strategy should reflect that behaviour.
Early investment can establish awareness and give customers time to consider the event. Later activity can focus on people who have already demonstrated interest or who are now closer to making a purchasing decision.
The right question is not “How many months should we advertise?”. It is “When does our audience actually decide to buy?”
Sometimes the Right Advertising Budget Is Smaller
There is a natural temptation to believe that more promotion must mean more sales.
But if an event is already selling quickly, has strong organic demand or is approaching capacity, additional advertising may have limited value.
In that situation, spending more could simply mean paying to reach people who were already likely to buy.
The opposite can also be true. If sales are weak, the answer is not automatically to increase the budget. The problem could be the event proposition, the price, the audience targeting, the landing page or the purchase experience.
Advertising cannot repair every problem in the sales journey.
Sometimes the most profitable marketing decision is to fix the conversion problem before buying more traffic.
Frequently Asked Questions
Q: How much should an event spend on advertising?
A: There is no universal amount or percentage. The appropriate budget depends on ticket economics, existing demand, audience size, sales targets, customer acquisition costs and the amount of additional demand advertising can realistically create.
Q: What is a reasonable customer acquisition cost for an event?
A: There is no standard figure. It depends on the contribution generated by an additional customer and the event's overall financial objectives. A £20 acquisition cost could be excellent for one event and unsustainable for another.
Q: Should an organiser spend a percentage of expected ticket revenue on advertising?
A: A percentage can be useful as a rough planning reference, but it should not determine the final budget. The economics of the event and the expected incremental return from advertising are more informative.
Q: Is ROAS enough to judge an event advertising campaign?
A: No. ROAS measures attributed revenue relative to advertising spend, but it does not account for the full cost of delivering the event or necessarily distinguish genuinely incremental sales from purchases that might have happened anyway.
Q: Why can advertising become less effective when the budget increases?
A: Once the most responsive audiences have been reached, additional spending may reach people who are less likely to purchase. Acquisition costs can rise and the number of additional sales generated by each extra pound can fall.
Q: Should a new event spend more on advertising?
A: It may need a larger investment because it has less existing awareness and fewer established audiences to rely on. However, the appropriate amount still depends on the event, market, audience and expected economics.
