Advertising agency: how the fee is built, what a campaign costs, and the clauses that decide ownership
Fee, media, production and ad technology are four separate bills. Here is what each one runs to in the US, what every fee model quietly rewards, and the terms that decide what you keep when the relationship ends.

An advertising agency is paid for its own time, and everything it buys on your behalf is a separate bill. In the US a regional advertiser on a retained relationship typically pays 8,000 to 30,000 dollars a month in fees, a defined campaign is more often quoted as a project at 15,000 to 150,000 dollars, and a small business buying only paid media management pays 1,500 to 5,000 dollars a month or 10 to 20 percent of what it spends on media. Media, production and ad technology sit on top of all of that. We built those numbers by watching how American shops quote rather than by surveying them, so they are most useful as a way to interrogate a proposal. The first thing to establish with any shop is which of the four bills its number covers.
The four bills, and who the money goes to
| Bill | How it is charged | Typical US figure |
|---|---|---|
| Agency fee | Retainer, project fee, blended hourly, or a percentage of media | 8 to 15 percent of media, or 125 to 350 dollars an hour |
| Media | Paid to the platform or station, usually billed through the agency | Whatever you commit, often a 10,000 dollar monthly floor to be worth managing |
| Production | Per asset, quoted before the shoot | 10,000 to 50,000 for a short digital film, 150,000 and up for national broadcast |
| Ad technology and data | Platform licences, verification, measurement | 5 to 15 percent of programmatic spend |
Three of those four are pass through costs. Ask for them to appear as pass through on the invoice, at the price the agency was charged, with the agency fee shown on its own line.
What each fee model quietly rewards
- Percentage of media. The traditional 15 percent commission has largely compressed to 8 to 12 percent, and 10 to 20 percent is common on programmatic where the agency carries platform costs. It is simple and it rewards spending more. Cap it, or step it down as spend rises.
- Flat retainer. Priced from a staffing plan, so ask for that plan: which people, at what percentage of their time. A retainer with no named hours is a number with a story attached.
- Project fee. The cleanest way to buy a campaign, because you are buying a defined set of assets and a launch date. Specify revisions and what a scope change costs.
- Performance or outcome based. Attractive on paper and argued over in practice, because attribution gets disputed at the exact moment the relationship is strained. If you use it, name the triggering event and the single data source in writing first.
What a campaign costs, by the shape of it
- A local push for one location. Fee 1,500 to 5,000 dollars a month, media 2,000 to 15,000, one set of creative at 3,000 to 12,000.
- A regional campaign across a metro or a few states. Fee 8,000 to 25,000 a month, media 25,000 to 200,000 a month, a creative platform plus adaptations at 25,000 to 90,000.
- A national launch. Fee 30,000 a month and up, broadcast and streaming production from 150,000, and a media commitment that makes the production worth it.
Most disappointment in this category is a mismatch of these three, usually a national quality creative idea funded with regional media money, so it is seen by almost nobody.
Agency of record, or project by project
An agency of record holds the brand, keeps a team on it, and knows your category without being briefed from scratch. You pay for that continuity in the months when nothing much happens. Project work costs less in total and more per asset, and the discontinuity shows by the third project when nobody remembers why the last idea was dropped. A company with a continuous calendar and several products is better served by the first. A company running two campaigns a year usually does better buying both as projects and keeping the brand guidelines in house.
Where the margin hides in digital buying
When an agency buys programmatic media through its own trading desk, the price you are billed and the price the inventory cost are not the same number, and the difference is legitimate revenue that should be visible rather than hidden. Four requests settle it: a disclosed fee on top of net media cost, platform access in your own name where the platform allows it, placement level reporting rather than a summary, and a written answer on whether the agency takes rebates from any media owner. A shop that answers all four plainly is the kind worth hiring. Our page on how the word leading gets used here goes further into verifying a shop's claims.
The rules the creative has to clear
US advertising law lands on the advertiser as much as the agency, so you need a shop that knows it. The Federal Trade Commission's guidance on endorsements and testimonials requires any material connection between you and a reviewer or influencer to be disclosed clearly, and its rule on consumer reviews bars buying or fabricating them. Health claims need substantiation held before the ad runs, not assembled afterwards. A healthcare advertiser cannot use a patient's story without a written authorization under the federal privacy rule that HHS administers. A law firm advertiser works inside its own state bar's advertising rules, which govern result claims and testimonials. Ask any shortlisted agency who reviews claims before a campaign ships and what happens if your legal team disagrees with the creative.
The clauses that decide what you keep
- Ad accounts in your name. Google Ads, Meta, LinkedIn, the TikTok account and the analytics property belong to your company, with the agency granted access. This one line is the difference between a cheap exit and an expensive one.
- Data and audiences. Customer lists, pixel data and built audiences are yours and must be exportable.
- Creative assets and working files. Not just the exported video, but the project files, the layered artwork, the fonts and their licences.
- Usage rights. Talent, music and stock are licensed by term, territory and media, so know the expiry dates before you build a campaign on them.
- Notice. Thirty to ninety days after an initial term, with placed media honoured and nothing new placed after notice.
When not to hire one
If your media budget is below roughly 2,000 dollars a month, the agency fee eats the campaign, and a freelance buyer or a few hours of setup from a specialist is the better purchase. If what you actually need is a steady stream of assets against an existing idea, a production partner or a design subscription costs less than a strategic agency. If nobody internally can approve work quickly, the agency will bill retainer months waiting on you. And if the brand positioning is still unsettled, campaign money spent now buys attention for a message you are about to change.
Questions a company asks before it appoints its first advertising agency
What is a realistic minimum to work with an advertising agency?
Most full service shops set a floor somewhere between 5,000 and 10,000 dollars a month in fees, because below that they cannot staff the account properly. Smaller independents and single discipline specialists work comfortably at 1,500 to 4,000 a month. If a large agency takes a small account at an unusually low fee, ask who will actually be on it.
Should the agency hold our media budget or should we pay the platforms directly?
Paying the platforms directly keeps the cash flow and the account history with you and is the stronger position. Many agencies prefer to bill media through themselves, which is reasonable for broadcast and out of home where they carry credit risk. For digital platforms there is rarely a good reason not to pay directly.
At what point is there enough data to call a campaign?
Paid search and paid social give readable signal in two to four weeks at reasonable spend. Brand campaigns on broadcast, streaming and out of home are judged over a quarter against a baseline recorded before launch, which is why the baseline has to exist before the first asset runs.
What should be in the brief we send out?
The business problem in one paragraph, who you want to reach and what they currently believe, the budget split between fee, media and production, the markets, the date something must be live, the mandatories your legal team will insist on, and the one number the work will be judged by. A brief with a budget range gets comparable proposals back. One without gets three differently shaped guesses.
The agency names an assistant offers when a marketing director asks
A marketing director short of time now often opens ChatGPT or Gemini and asks which shops handle advertising for a category like theirs. Three or four names come back with a line of reasoning each, and that set is assembled from trade press, award databases, directories and case study coverage rather than from search rankings or from the agency's own reel. It means a shop with a beautiful site and no third party footprint can be invisible in exactly the moment a buyer is forming a longlist, and a smaller independent with consistent press can be named first. The same holds for your own brand when somebody asks an assistant who to buy from in your category. AI Knows Us records those answers across the assistants and shows which pages each one leaned on, which turns a vague worry into a list of places worth being written about.
