How Much Do PPC Agencies Charge? A Straight Answer, With Real Numbers

The three pricing models, and what each one really means

Agency pricing is not standardized, which is exactly why comparing proposals is so frustrating. One firm quotes a percentage, another quotes a flat number, a third bundles ad management into a larger retainer. They are not comparable until you convert everything to dollars per month.

1. Percentage of ad spend (10–20%)

The agency takes a cut of whatever you spend. Spend $10,000, pay $1,500 at a 15% rate. It is simple, it scales with account size, and it is the default across most of the industry.

It also contains a structural conflict that is worth stating plainly: your agency's revenue increases when your budget increases, whether or not the additional spend produced profit. Nobody has to be dishonest for this to distort advice. When the recommendation to raise budget is also the recommendation that raises the agency's own invoice, that advice is no longer neutral — and the client is rarely in a position to audit it.

There is a second problem. Efficiency work — cutting wasted spend, tightening negatives, killing unprofitable campaigns — directly reduces the agency's fee. The single most valuable thing a PPC manager can do for a struggling account is spend less money better, and this model charges them for doing it.

2. Flat monthly retainer

A fixed fee, agreed before you spend anything. Typically $1,000–$5,000 per month depending on account complexity, number of channels, and how much strategy and reporting is bundled in.

The advantages are predictability and aligned incentives. Your fee does not move when your budget moves, so the agency can honestly recommend pausing a campaign, cutting spend in a slow month, or shifting budget to a cheaper channel. Scaling a winning campaign does not trigger a bigger invoice.

The tradeoff: a flat fee on a very small budget can be uneconomical for the client. If you are spending $800 a month on ads, a $1,500 management fee means you are paying nearly twice as much to manage the money as you are spending on it. Below roughly $1,500 in monthly ad spend, running campaigns yourself is usually the rational choice.

3. Hybrid (base fee plus percentage)

A smaller base retainer covering the floor of the work, plus a reduced percentage on spend above a threshold. It softens the worst of both models but reintroduces the same incentive problem in miniature. Ask what the percentage is and what it applies to.

What PPC management actually costs in San Diego

Concrete ranges for a San Diego business, management fee only, ad spend excluded:

For transparency, here is our own pricing: Click Track Marketing charges a flat monthly fee — $2,000, $3,500, or $6,500 per month depending on scope — and never a percentage of ad spend. Those are full marketing retainers that include PPC management alongside SEO, conversion tracking, and CRM automation, not ad management sold in isolation. The full breakdown is on our pricing page.

Costs that hide outside the management fee

The fee is not the whole cost. Before you compare proposals, confirm which of these are included and which are billed separately:

• Setup or onboarding fees — commonly $500–$3,000 one time, sometimes waived on longer commitments.
• Landing page design and development — many agencies manage ads but will not build the page the ads point to, which is often the actual bottleneck.
• Call tracking software — typically $30–$150 per month, and essential for any service business where most leads arrive by phone.
• Creative production — ad copy is usually included; video, photography, and display creative frequently are not.
• Third-party reporting tools — some agencies pass these through at cost, others absorb them.

The number that actually matters

Management fee alone is the wrong comparison. What matters is blended cost per acquisition: ad spend plus management fee, divided by customers acquired.

An agency charging $3,500 that delivers 90 leads is cheaper per lead than one charging $1,500 that delivers 20. We publish our own numbers for exactly this reason — our client Lifetime Custom Painting generates roughly 89 leads a month at a blended $68 cost per lead across Google Ads and Local Services Ads. That is the figure worth asking any agency for, and the one most will avoid answering.

For a benchmark to judge any agency against, the 2026 Google Ads benchmarks from WordStream / LocaliQ — drawn from 13,474 US search campaigns run between April 2025 and March 2026 — put the all-industry average cost per lead at $66.69 on an average CPC of $5.42. By vertical: legal $131.63, home improvement $90.92, dental $72.97, restaurants $30.57. If an agency cannot tell you where you sit against those numbers, they are not measuring the thing you are paying them to improve.

Questions to ask before you sign

1. 1What is the fee in dollars per month, not as a percentage?
2. 2Does the fee change if my ad spend changes? At what threshold?
3. 3What is billed separately — setup, landing pages, call tracking, creative?
4. 4Who owns the Google Ads account, and what happens to the data if I leave?
5. 5What is the contract length, and what is the cancellation notice period?
6. 6Can you show a real client's cost per lead, redacted if necessary?

Price is only half the decision. Once you have comparable numbers, work through the seven questions that reveal how an agency actually operates — starting with who owns the ad account. And if you want a second opinion on what you are currently paying and what it is producing, our San Diego PPC agency team will audit your account and show you where the budget is leaking, whether or not you end up working with us.
