Performance-based or fixed fee?

We are a performance-based agency, so read this with that in mind. Here is what the four common fee models reward, what should be in the contract, and when performance-based doesn’t fit.

By Victor Skretteberg, Arcads · Updated September 28, 2026

Short answer: A fixed fee gives you a predictable price, but the agency gets the same regardless of results. Hourly rates reward hours, and a percentage of budget rewards a bigger budget. A performance-based fee ties the agency’s income to what the ads create, but only fits when results can be measured and the volume is large enough. With us, the share is 5–10% of what we earn you, and it has to realistically be able to reach around NOK 20–30,000 a month.

The four models, and what they reward

Over time, an agency does the most of whatever it gets paid for. That isn’t cynicism, just how incentives work. So compare what agencies make money on before you compare prices.

ModelHow the price is setThe agency earns the most when …
Fixed monthly feeA fixed amount per month. Varies a lot, from a few thousand kroner for basic management to much more for large accounts.… you stay. The results don’t affect the invoice.
Hourly rateHours spent × hourly rate… a lot of hours are spent.
Percentage of ad budgetA percentage of what you spend with Google and Meta… the budget goes up, even when it doesn’t pay off.
Performance-basedA share of the value the ads create (5–10% with us)… the ads create measurable value. Otherwise it earns nothing.

Fixed fee: predictable

A fixed fee is the most common model, and the upside is that you know what you pay. The downside shows up after a few months. The account runs okay, no crisis, and the invoice arrives regardless. For the agency, new ads and bigger changes are a risk with no upside. That leads to accounts that run steadily for years without growing. A good agency on a fixed fee still works for results, but then it’s in spite of the model.

Hourly rate and percentage of budget

An hourly rate is clean when the job is well-defined, like setting up tracking or reviewing the account. For ongoing management, it rewards time spent, not impact. A percentage of budget is open about what it is: the agency gets more when you spend more. That’s fine when a bigger budget is right, and unfortunate when it isn’t, because no one in the contract benefits from saying the budget should come down.

Performance-based: what it means with us

We take a 5–10% share of what we earn you, measured in your own account. No fixed monthly fee. If you don’t earn more, you pay us nothing. You pay the ad budget directly to Google and Meta.

For it to work for us, the share needs to reach around NOK 20–30,000 a month. With a 5–10% share, that means the ads need to create somewhere between NOK 200,000 and 600,000 in value a month. That’s why we work with established businesses with a monthly ad budget of at least NOK 30,000.

The model requires three things:

  1. Trackable results. Sales in an online store and inquiries through a form can be measured. Brand awareness can’t. If the goal is “visibility,” there is nothing to calculate the fee from.
  2. Enough volume. The share has to be able to grow large enough for the agency to live on it, as above.
  3. Agreement on what value is. For an online store, it’s the profit on the sales the ads generated, not the revenue. For a lead-based business, it’s inquiries × what an inquiry is worth. The number has to be agreed before you start and be readable in the account, or there will be disagreements later.

The downside: performance-based agencies are picky. They lose money on clients where the math doesn’t add up, so they don’t take everyone. If you get a no, it’s usually because the ads can’t realistically create enough for your business right now.

When a fixed fee is right

If the business is early-stage, the budget is small, or you need help with things that don’t produce measurable numbers in the short term (brand, content, website), a fixed fee or hourly rate is more honest for both sides. Then you are buying time and expertise, and should judge it as such. Still, ask for a report that shows sales and inquiries, not just clicks.

The questions that reveal the model

  • What happens to the invoice in a bad month?
  • How do you measure what I’m paying for, and can I see it in my own account?
  • Is there a lock-in period? A long lock-in means the agency gets paid even in the months it doesn’t deliver.
  • When do you say no to a client?

We have ten more questions here, and they apply to us too. How our model is calculated is on the pricing page.

Questions and answers.

How much does a marketing agency cost in Norway?+
It varies a lot. A fixed fee can be anything from a few thousand kroner a month for basic management to much more for large accounts. Other agencies charge by the hour or a percentage of the ad budget. Performance-based agencies take a share of the value the ads create, and nothing if the value doesn’t materialize. Always ask what happens to the bill in a bad month.
How does Arcads charge?+
We take a share of the value we create for you, not a fixed monthly fee. If you don’t earn more, you pay us nothing. For it to work for both sides, the ads need to be able to create enough for our share to reach around NOK 20–30,000 a month. That’s why we work with established businesses with a monthly ad budget of at least NOK 30,000. You pay the ad budget directly to Google and Meta.
Is a performance-based fee more expensive?+
In good months it can be, because the agency gets a share of more. In a month where the ads don’t create more, you pay nothing. Over time, you pay for what the ads create, not for the time that went by.
Does performance-based work for small businesses?+
Only if results can be tracked and the volume is large enough for the share to be worth it for the agency. With us, that means the share must be able to reach around NOK 20–30,000 a month. If you are below that, a fixed fee, an hourly rate or doing it yourself are better choices.
What should be in a performance-based contract?+
What counts as value and where it is measured, how big the share is, that you own the ad accounts and the data, what applies to termination, and how tracking is verified.
