What changed
- First published. Fees, churn and tenure figures verified against the ANA and 4As tenure report, the Focus Digital churn study and published PPC pricing benchmarks. Agency creative read from the Meta Ad Library the same day.
What does a marketing agency cost in 2026?
The standard management fee is 10 to 20 percent of ad spend, and 15 to 20 percent is typical for Google Ads at smaller budgets. Small accounts often pay $500 to $750 a month, mid-sized accounts $1,500 to $2,500, on top of the spend itself.
Agency pricing is unusually consistent across the industry: a percentage of what you spend, charged monthly, on top of the money going to Meta and Google. Published PPC pricing benchmarks put the standard band at 10 to 20 percent, with the higher end applying to smaller budgets.
| Your monthly ad spend | Fee at 10% | Fee at 15% | Fee at 20% | Annual fee at 15% |
|---|---|---|---|---|
| $10,000 | $1,000 | $1,500 | $2,000 | $18,000 |
| $50,000 | $5,000 | $7,500 | $10,000 | $90,000 |
| $100,000 | $10,000 | $15,000 | $20,000 | $180,000 |
| $250,000 | $25,000 | $37,500 | $50,000 | $450,000 |
How long do agency relationships actually last?
High churn is standard at the small and mid end of the market. Agencies under ten staff lose about a third of their clients every year, project-based agencies lose 42 percent, and roughly 43 percent of B2B churn happens inside the first 90 days.
Agencies churn clients, and everyone in the industry knows it: the trade press runs a reviews-and-losses column, and agency operators publish retention playbooks because retention is the problem. The numbers put a floor under the anecdote.
Long relationships do exist, mostly at the top of the market where procurement and a multi-year contract do the holding: the ANA and 4As put average agency-of-record tenure near seven years and media agencies at 3.7 years among the largest advertisers. Below that tier, where most businesses live, it looks nothing like that.
| Measure | Figure | Source |
|---|---|---|
| Annual churn, agencies under 10 staff | 32% | Focus Digital, 2025 |
| Annual churn, project-based agencies | 42% | Focus Digital, 2025 |
| Share of B2B churn inside the first 90 days | ~43% | Focus Digital, 2025 |
| Average client lifespan, project model | 24 months | Focus Digital, 2025 |
| Average client lifespan, retainer model | 56 months | Focus Digital, 2025 |
| Media agency tenure, largest advertisers | 3.7 years | ANA / 4As, 2025 |
| Average AOR tenure, largest advertisers | ~7 years | ANA / 4As, 2025 |
Do marketing agencies run ads for themselves?
Mostly not. Of fifteen well-known performance agencies checked in the Meta Ad Library, seven run any Meta ads at all, and between them they run 169 ads. One mid-size skincare brand runs 833.
An agency selling paid social is making a claim about paid social. The cheapest way to test that claim is to look at whether they buy it themselves, which is public information for anyone who asks the ad library.
| Agency | Ads in the library | Still running | Median run length |
|---|---|---|---|
| Lyfe Marketing | 50 | 47 | 212 days |
| Hawke Media | 42 | 42 | 87 days |
| Disruptive Advertising | 31 | 28 | 115 days |
| Power Digital Marketing | 30 | 30 | 9 days |
| WebFX | 9 | 9 | 85 days |
| KlientBoost | 4 | 4 | 10 days |
| Ignite Visibility | 3 | 3 | 3 days |
| Eight others checked | 0 | 0 | n/a |
Two details are worth more than the totals. WebFX’s Meta advertising is recruiting, not client acquisition: the ads say "Apply for a Digital Marketing Position" and "Ready to launch your digital marketing career?". And Ignite Visibility’s three ads have a median run of three days, which is a test that was never scaled rather than a programme.
Can AI replace a marketing agency in 2026?
For the work that runs an account day to day, yes. An AI agent reads the account, proposes changes, and makes them once you approve, at a flat price that does not rise with your spend. Strategy, brand and original production are still human work.
The agency retainer buys a bundle: someone watching the account, someone writing the ads, someone building the reports, and someone in a monthly meeting explaining the first three. An agent does the first, third and much of the second continuously rather than in a weekly cycle, which changes both the cost and the latency.
| Agency retainer | Sprites | |
|---|---|---|
| Pricing | 10 to 20 percent of ad spend | Flat, from $66/mo billed yearly |
| Cost at $50k monthly spend | $5,000 to $10,000 a month | Unchanged |
| Cadence | Weekly or monthly reviews | Continuous, with approval on every change |
| Channels | Usually one or two | Meta, Google and LinkedIn, plus SEO and AI visibility |
| Competitor research | Manual, if it happens | Built in, free to browse |
| Reporting | A monthly deck | Live, and readable any time |
| Who makes the change | The agency, on their schedule | You approve, the agent executes |
The honest limit: an agent is not a brand strategist and does not film anything. If what you need is a positioning exercise, a production shoot or a campaign idea worth a year of media, hire people. If what you need is the account watched, tested and reallocated every day, that is the part software now does better than a monthly meeting.
When is an agency still the right call?
When the work is creative production, brand strategy or a campaign that needs people, and when your spend is large enough that a percentage fee buys genuine senior attention.
- You need original video, photography or design at volume, and you do not have a studio.
- You are repositioning the brand, which is a strategy problem rather than an account problem.
- Your spend is large enough that 5 to 10 percent buys a senior team rather than a junior one.
- You are entering a market where local knowledge matters more than optimisation.
The mistake is not hiring an agency. It is paying agency rates for account maintenance, which is the part of the bundle that has changed most since 2024.

Frequently asked questions
How much do marketing agencies charge to run ads?
The standard management fee is 10 to 20 percent of monthly ad spend, with 15 to 20 percent typical for Google Ads at smaller budgets. Small accounts often pay a flat $500 to $750 a month and mid-sized accounts $1,500 to $2,500, charged on top of the ad spend itself.
How often do companies fire their marketing agency?
High churn is standard outside the largest accounts. Agencies with fewer than ten staff lose about 32 percent of their clients a year and project-based agencies 42 percent, with roughly 43 percent of that churn happening inside the first 90 days. The long tenures reported in industry surveys, around seven years, describe agency-of-record relationships at the largest advertisers.
Do marketing agencies run their own ads?
Most do not. Of fifteen well-known performance agencies checked in the Meta Ad Library in September 2026, seven ran any Meta ads at all, and together they ran 169 ads. Some of that is recruiting rather than client acquisition.
Can AI replace a marketing agency?
It can replace the account management layer: watching performance, testing creative, reallocating budget and reporting. It does not replace brand strategy or original production. An AI agent also prices flat rather than as a percentage of spend, so the cost does not rise as the budget does.
Is it cheaper to run ads in house with AI than to hire an agency?
At $50,000 a month in ad spend, a 15 percent agency fee is $7,500 a month, or $90,000 a year. Software priced flat does not move with spend, so the gap widens as the budget grows. Below roughly $10,000 a month in spend, the comparison is closer and depends on how much creative production you need.
Run the account yourself, with an agent doing the watching
