What does a marketing agency cost?

Short answer
Marketing agencies typically price one of three ways: a fixed monthly retainer, a percentage of ad spend, or a performance-based model. The price varies with scope and model — what matters is that the incentive points toward your profit, not just more spend.
Sådan virker det
Marketingbureauer prissætter typisk på én af tre måder: fast månedlig retainer, en procentdel af annoncebudgettet, eller en performance-model. Hver har fordele og skævheder — det vigtige er, at incitamentet peger mod jeres profit, ikke bare mod mere spend.
01The three pricing models
A fixed retainer is an agreed monthly price for a defined scope. It's predictable and keeps the agency independent of your budget — but it doesn't scale automatically with results. Percentage of ad spend ties the fee to your spend; it's simple, but creates a bias: the agency earns more the more you spend, whether or not it's profitable.
Performance-based models tie payment to results (e.g. a share of growth). They realign the incentive, but require agreement on what a “result” is and how it's measured honestly — which is harder than it sounds when attribution can be inflated.

02Look at the incentive, not just the price
The most important question isn't what the agency costs, but what it's incentivised to optimise for. A model that rewards more spend pulls in one direction; one that rewards your profit and bottom line pulls in another. Always ask to understand how the fee connects to your real results.
This is also where the difference between an agency and a growth partner becomes concrete: a partner whose success is tied to your profit makes different decisions than a vendor billed by the hour or by spend. Price should be weighed against who carries responsibility for the bottom line.
Frequently asked questions
Which agency pricing model is best?+
There's no single right one — it depends on what you want aligned. A retainer gives predictability and independence from spend; percentage-of-spend is simple but biased; performance realigns the incentive but demands honest measurement. What matters is that the model points toward your profit.
Why is percentage of ad spend problematic?+
Because it rewards the agency for getting you to spend more, regardless of whether that extra spend is profitable. The incentive points toward volume over bottom line — the opposite of profit-led management.

Comparison
Agency vs. growth partner
A classic agency delivers services and hours on individual channels. A growth partner owns the total result — strategy, tech and execution under one roof, steered toward profit and the bottom line rather than deliverables.

Agency vs. freelancer: which should you choose?
A freelancer usually handles one channel well and cheaply, but without the technical foundation and the strategic whole. An agency or partner ties channels, tracking, data and strategy together. The choice depends on whether you need help with one task or a system that works together.

What is POAS?
POAS (Profit on Ad Spend) is your gross profit divided by ad spend. Where ROAS measures revenue per ad euro, POAS measures what you actually keep — after cost of goods, shipping and fees.

What does performance marketing cost?
Performance marketing costs three things: media budget (the biggest item, paid to the platforms), management (in-house, freelancer or partner) and tech (tracking, tooling). There's no fixed price — what counts is whether the whole effort pays for itself on the bottom line.
