Key takeaways
- A 10% fee on ad spend turns a $5,000 monthly budget into a $500 fee and a $50,000 monthly budget into a $5,000 fee, for work that often takes the same number of hours.
- Hourly billing rewards slow work. An agency has no reason to finish a landing page fix faster if every hour adds to the invoice.
- Fixed monthly retainers separate the fee from spend. The agency earns more only by taking on more scope, not because your budget grew.
- Meant runs retainers month to month and never as a percentage of ad spend, with ad accounts opened in the client's own name.
- Projects at Meant start at $2,000 on a fixed scope and fixed price, agreed in writing after a free 30-minute call, before any work begins.
How percentage of ad spend pricing actually works
Percentage of ad spend pricing means the agency's management fee is a fixed share of what you spend on media each month. It costs more than it should because the fee rises in step with your budget, while the work rises slowly or not at all. At Meant we price the other way: a written scope, a fixed fee and a retainer you can stop at the end of any month.
The formula is simple:
Monthly fee = monthly ad spend × agreed percentage
The media itself is paid to Google or Meta separately. The percentage sits on top. Many contracts also add a minimum monthly fee, so a small budget still pays a floor amount.
The standard range agencies quote
There is no single industry rate. Quotes vary by agency, channel and budget, and some agencies use a sliding scale where the percentage falls as spend rises. We use 10% in the examples in this article because it is a round number that makes the maths easy to follow, not because it is a benchmark. Whatever rate you are quoted, the mechanic is the same: your budget sets the fee.
What the fee is supposed to pay for
The fee is meant to cover the people managing the account:
- strategy and campaign structure
- keyword and audience research
- ad copy and creative testing
- bid and budget management
- conversion tracking
- reporting
The argument for tying this to spend is that a bigger budget carries more risk and deserves more attention. That is partly true. But most of the work above scales with the number of campaigns, markets and products, not with the size of the number in the budget field.
The maths: what happens to the fee as spend scales
Here is a 10% agency fee as a percent of spend at four budget levels.
| Monthly ad spend | Fee at 10% | Annual fee | What usually changes in the work |
|---|---|---|---|
| $5,000 | $500 | $6,000 | Account setup, tracking, a handful of campaigns |
| $10,000 | $1,000 | $12,000 | Same campaigns, higher daily budgets |
| $25,000 | $2,500 | $30,000 | Perhaps more ad variations to test |
| $50,000 | $5,000 | $60,000 | Same structure, larger numbers in the budget field |
Real budgets cover a far wider spread than this. A 2019 ANA survey of 86 advertisers found annual US media spend ranging from under $30 million to $500 million or more. At any rate, a percentage scales across that whole range, whether or not the work does.
Spend doubles, fee doubles, work stays flat
Moving from $25,000 to $50,000 a month in Google Ads rarely means twice the campaigns or twice the reporting. Often it means raising daily budgets on campaigns that already work. That is a settings change. Under percentage of ad spend pricing, it also doubles the fee: an extra $2,500 a month, or $30,000 a year, for broadly the same hours.
This matters most when a business moves from launch into paid growth. The growth ads that carried Shordex after launch sit in exactly that phase. Shordex is an institutional-grade DeFi platform, and the site and brand narrative came first, with paid growth after. That is the point where budgets tend to rise, and where a percentage fee starts charging for the rise rather than for the work.
Where the incentive points once the fee is tied to spend
This is not a claim that agencies on percentage deals act in bad faith. It is a claim about structure. If the fee is a share of spend, then:
- recommending a bigger budget raises the agency's income
- cutting wasted spend lowers it
- pausing a campaign that does not convert costs the agency money
A good account manager will still do the right thing. The contract just does not reward them for it. Some advertisers try to fix this by paying on outcomes instead. An earlier ANA survey found sales commissions, where the agency earns a percentage of the brand's sales, were used in 15 percent of compensation plans, rising to 41 percent among packaged goods marketers.
Hourly billing: the other way agencies make scope expensive
Hourly billing looks like the honest alternative to an agency fee as a percent of spend. You pay for time, not for budget. It is also the most common model. ANA's Trends in Agency Compensation report found labour-based fees remain the dominant form of agency compensation, and that smaller advertisers are much more likely to use them, at 76 percent.
Why slow work pays better under an hourly contract
Under an hourly contract, a landing page fix that takes three hours earns less than one that takes nine. Nobody has to drag their feet on purpose for the incentive to matter. Extra rounds of revisions, longer meetings and slower handovers all bill. Speed, which is what you want, is what the contract penalises.
What hourly billing hides from the client
An hourly invoice tells you how long something took. It rarely tells you:
- who did the work, and at what level of seniority
- whether the hours went on your priorities or on the agency's learning curve
- how the time was rounded
- what the final cost will be before the work starts
You only learn the price after the work is done, which is the opposite of how you would buy almost anything else for a business.
Fixed scope and fixed retainer pricing, compared
Fixed scope pricing starts from deliverables. ANA describes a fixed, output-based model as one where the fee is negotiated for a specific project or set of deliverables without regard to the agency labour time involved. The same report found 53 percent of marketers spending $500 million or more a year now use fixed or output-based fees, up from five percent in 2016.
| Percentage of ad spend | Hourly billing | Fixed scope or fixed retainer | |
|---|---|---|---|
| How the fee is set | Share of monthly media spend | Hours logged × rate | Agreed price for written deliverables |
| What makes it grow | Your budget rising | More hours, faster or not | More scope, agreed in writing |
| Known before work starts | Only if spend is fixed | No | Yes |
| Rewards the agency for | Spending more | Taking longer | Delivering the scope well |
| Cutting wasted spend | Lowers the agency's fee | No effect | No effect |
What a fixed retainer actually covers
A performance marketing retainer should list its scope the way a build contract does. That means the channels (Google Ads, Meta, or both), the number of campaigns or markets, how often creative and copy are tested, what landing page changes are included, how conversion tracking is maintained, and when you get reports. If it is not written down, it is not in the fee.
Why a fixed fee aligns incentives with results, not spend
With a fixed fee, the agency earns the same whether you spend $10,000 or $40,000 a month. The only way to keep the client is to show that the spend is working. Recommending a lower budget costs the agency nothing. Recommending a higher one earns it nothing. That leaves the advice free to follow the numbers.
Questions to ask before you sign a performance marketing contract
Use these when comparing Google Ads agency pricing from any agency, including us. If a contract has legal or tax implications for your business, have it reviewed by a qualified adviser before you sign.
Who owns the ad account
Ask whether the Google Ads and Meta accounts will be opened in your company's name, with billing on your card. If the agency owns the account, your campaign history, audiences and conversion data can leave with them. Owning the account also means you see exactly what was paid to the platform, which makes any mark-up visible.
What happens if spend changes mid-contract
Ask the agency to show, in writing, what the fee becomes if your budget doubles or halves. Under a percentage deal it moves automatically. Under a fixed retainer it should only move if the scope changes. Also ask about notice periods and minimum terms: how many months you are committed to, and what it costs to leave.
What the fee covers beyond media buying
Many contracts cover bids and budgets and stop at the edge of the ad platform. Ask who changes the landing page when it does not convert. Paid clicks are wasted on a slow or unclear page, so the fee should include, or at least name the cost of, a landing page built to convert the traffic you're already paying for. If the agency cannot edit your site, find out who can and how long it takes.
A short checklist to take into every call:
- Is the fee a percentage of spend, hourly, or fixed?
- Is the scope written down, with deliverables listed?
- Are the ad accounts in my name?
- Does the agency receive any rebate, commission or incentive from platforms or vendors?
- What is the notice period?
- Who changes the website?
How Meant prices websites, automation and ads differently
We are a small senior studio, and the same team that designs and builds a site also runs the marketing for it. Our commercial rules are short.
Fixed price, agreed before work starts
Every build starts with a free 30-minute call. After it, we write the scope and quote one price for it. Projects start at $2,000. There is no hourly billing and no charge for the first call. That applies to Next.js marketing sites and bilingual EN/AR builds, headless Shopify storefronts (the shop front built as custom code, with checkout kept in Shopify), and AI and WhatsApp automation. The same terms apply whether the job is a landing page or the digital architecture and brand narrative for a platform like Shordex. You can read how we quote a fixed price for a written scope before you speak to us.
Retainers that are never a percentage of spend
Automation and marketing run as monthly retainers. They are month to month, so you can stop at the end of any month. They are never a percentage of ad spend. Ad accounts are opened in your name, and the fee changes only if the scope does, agreed in writing first. If you want to compare our terms with the quotes on your desk, book the free 30-minute call.
Frequently asked questions
What is a typical percentage of ad spend agencies charge?
There is no single published standard for search and social, and rates vary by agency and budget. For influencer marketing specifically, an ANA study reported that 30% of influencer marketing spending is paid to agencies on average, against 70% to influencers. Whatever the rate, work out the annual fee at your current budget and at double it before you compare quotes.
Is percentage of ad spend or flat fee better for a small budget?
On a small budget, a percentage can look cheap, but many agencies add a minimum monthly fee that removes the saving. A flat fee tells you the full cost up front and does not rise as you grow. The right choice depends on your plans for spend over the next year, so model both at your expected budget.
Do agencies that charge a percentage of spend also take media rebates?
Some parts of the media industry do involve rebates or incentives, and compensation is not always visible to the client. A 2026 ANA study found 61% of senior marketing executives use influencer agency compensation models that are either non-transparent or unknown. Ask any agency to state in writing whether it receives rebates, and keep the ad account in your own name so you see the platform invoices directly.
Can you negotiate a cap on a percentage of ad spend fee?
Yes. You can ask for a monthly cap, a sliding rate that falls as spend rises, or a switch to a flat fee above a set budget. A cap limits the cost but keeps the incentive to raise spend below it. If you are negotiating a cap, it may be simpler to ask for a fixed retainer with written scope instead.
How do fixed retainers handle a sudden increase in ad spend?
Under a fixed retainer, a bigger budget on the same campaigns does not change the fee. If the increase brings new work, such as new markets, channels or landing pages, the scope is revised and the new fee agreed in writing before it applies. At Meant the retainer stays month to month either way.
If you want a marketing fee that doesn't grow just because your ad budget did, book the free 30-minute call with Meant and we'll quote a fixed monthly retainer in writing, never a percentage of spend.
