Marketing & Agency
There's no single honest number here — cost depends on which pricing model an agency uses and how complex your account is, and any site that hands you one flat industry-average figure is simplifying past the point of being useful. What follows is the actual range of pricing structures in use, and the specific things that push a quote up or down.
Most agencies use one of these, or a combination. None is inherently the "correct" model — each has a genuine trade-off.
Flat monthly retainer
A fixed fee regardless of how much you spend on ads. Predictable for budgeting, and it doesn't create any incentive for the agency to push your spend higher than it should be. The trade-off: if your account genuinely grows more complex over time, a flat number agreed months ago may no longer reflect the actual work involved, unless it's revisited.
Percentage of ad spend
The fee scales with how much you spend — commonly somewhere in the high single digits to mid-teens as a percentage, though this varies a lot by agency and account size. It aligns the agency's revenue with your spend growing, which isn't quite the same as aligning it with your results improving. Worth reading closely if you're comparing this against flat fees.
Hourly
Less common for ongoing management, more common for audits, one-off projects, or consulting engagements. Transparent in theory, but hard to budget against if scope isn't tightly defined up front.
Hybrid retainer + performance
A lower base retainer plus a bonus or performance component tied to results — often revenue, ROAS, or a specific KPI hit. Can align incentives well, but only if the performance metric is one you'd actually stand behind (platform-reported ROAS is a common but flawed choice — see the note on measurement below).
One-time setup or onboarding fee
A separate charge for the initial work — account audit, tracking review, campaign structure rebuild — before ongoing management fees start. Reasonable if it reflects real upfront work; worth asking exactly what's included.
Creative or landing-page fees as add-ons
Many agencies scope creative direction into management fees but charge separately for actual production — photography, video editing, landing page builds. If creative or dedicated landing pages matter to your strategy, confirm what's included versus billed extra before signing anything.
The two dominant models — flat fee and percentage of ad spend — get compared in more depth, including the specific incentive problems each one creates, in percentage of ad spend vs fixed fee.
Account complexity
A single-channel account with a handful of evergreen campaigns costs less to manage well than a catalogue with hundreds of SKUs, multiple markets, or frequent promotional changes.
Number of channels
Meta only, Google only, or both together — and increasingly TikTok or other platforms — each channel adds management time, even where some efficiency comes from shared learnings across them.
Creative production needs
Agencies that write briefs and analyze results cost less than agencies also producing video, photography or UGC-style content in volume.
Spend level
Higher spend generally means more testing, more budget decisions, and more reporting depth expected — which is the logic behind percentage-of-spend pricing, even though spend alone isn't a perfect proxy for effort.
Reporting and analytics depth
Monthly PDF reporting is cheaper to deliver than a live dashboard tied to real order data, deeper attribution modeling, or bespoke reporting cadence.
Market
Agency rates vary by region and by how competitive the local agency market is, the same way any professional service does.
We're not going to hand you a specific "average agency cost" number — nobody publishing one has actually surveyed a representative sample of agencies, and most of those figures circulating online trace back to nothing more than another blog post doing the same thing.
What's reasonable to say, based on how these pricing models generally work rather than any specific data source: a small, single-channel account on a flat retainer tends to sit at the lower end of what agencies charge for ongoing management, a multi-channel account with meaningful creative production needs sits meaningfully higher, and percentage-of-spend pricing scales roughly in proportion to your monthly budget regardless of account size. Treat any of these as a starting point for a conversation, not a number to hold an agency to before they've actually looked at your account.
The only reliable way to get an actual number for your situation is to have a specific agency review your account and quote against what they'd actually be doing — which is why we don't publish a flat management rate either. Send an inquiry and you'll get pricing based on your account, not a rate card.
We manage Meta and Google Ads with the same focus on measurement, tracking and actual business performance described in this guide.
