Many fractional CMOs charge $3,000–$15,000 a month for 10–20 hours a week, per the published rate guides at MarketerHire, Chief Outsiders, and Kalungi. Our own retainers at Carson Poore Consulting are $1,200, $2,400, or $4,800 a month. Published, 3 months minimum, then month to month.
That's the short version. The longer one is below, and it includes the question that matters more than price... whether you should buy this at all.
What moves the number
Three things set the price: hours, seniority, and who the provider was built to serve.
Hours first. The standard engagement is part-time, and fewer hours means a lower retainer. Don't get us wrong, a senior operator's time is real money anywhere you buy it.
Seniority second. Someone who has run marketing through two growth stages charges more than someone 2 years out of an agency job, which is why rates in those same guides stretch so wide.
The third one is the part nobody tells you. So here's our hot take: the market's price floor was set by startups. Nearly every firm ranking for this question serves Series A and B companies, funded, with a 2-to-6-person marketing team already in place for the CMO to direct. A premium price floor makes sense for that buyer. It makes much less sense for a $900K plumbing company in Greenwood or a 2-founder software business that hasn't raised a dime.
In our book, most businesses under $2M in revenue are getting quoted by a market that wasn't built for them. That's an opinion. The table below is not.
Fractional CMO vs. agency vs. full-time hire
| Fractional CMO | Marketing agency | Full-time CMO | |
|---|---|---|---|
| Typical cost | A monthly retainer, in the range above | Rarely published. Most firms quote after a sales call. | $175K–$300K+ a year before benefits (MarketerHire) |
| What you're buying | Senior strategy and direction, part-time | Execution capacity on specific channels | Leadership, all week, every week |
| Hours on your business | Part-time, a set number of hours each week | Varies by retainer; attention is split across accounts | 40+ |
| Who owns the outcome | The CMO owns the plan and the number | The agency owns deliverables and channel metrics | The CMO |
| Fits best when | Revenue is past the guesswork stage and there's a strategy gap | You've proven a channel and need hands | A large business with a team to lead |
It's not one or the other. You're buying clarity from a fractional CMO and capacity from an agency. That's the frame nearly every comparison piece lands on, and it's roughly right. A full-time hire gets you both, at a salary most small businesses can't carry. We wrote up the agency comparison in full, trade-offs included, in fractional CMO vs. marketing agency.
The guides above repeat a savings pitch: fractional costs a fraction of the full-time equivalent. True as far as it goes. But the savings math assumes you were ever going to pay a six-figure marketing executive, and if you're reading this, you probably weren't. Compare against what you'd actually do instead, which is usually a junior hire or an agency retainer. Or nothing.
Where our pricing sits
Our fractional CMO work runs through the coaching & growth practice. The retainers are $1,200, $2,400, or $4,800 a month, depending on scope. A one-time strategy engagement is $3,000, and if you move to a retainer afterward, half that fee ($1,500) is credited toward it. 3 months minimum, then month to month. We take 8 clients at a time, and if you ever leave, you keep everything: your site, your Google Business Profile, your ad accounts, and your data. Full terms are on the pricing page.
Those numbers sit under the market's published floor on purpose. We built for the segment the $5,000-and-up firms skip: owner-run companies and early-stage founders, with a reduced rate for nonprofits. And the people writing your plan are the same team building the automation and the ad account, so you're not paying a strategist's rate for work that's really coordination.
One thing, said plainly: we're not a neutral narrator here. This article prices the thing we sell. That's exactly why the market figures above say where they come from.
When a fractional CMO isn't worth it
Before product-market fit, don't hire one. If people aren't buying yet, the problem is the offer or the audience, and a retainer won't fix either. Buy a one-time plan at most, do the homework yourself, and come back later. We turn down pre-PMF retainer inquiries, and we'd rather tell you that here than on a call.
If you've already proven a channel and just need more hands on it, you don't need strategy by the month. Hire an agency or a good freelancer for that channel. Cheaper, and honestly a better fit.
And there's a structural failure worth knowing before you shop. Automate the Journey, whose piece on this question ranks for a reason, names the pattern: a fractional CMO "gives you the plan but doesn't run the work." You end up with a strategy deck and nobody to execute it. Ask any candidate who implements, by name, before you sign. Our answer is that the same team does both. Other good answers exist. No answer is a red flag.
So here's the one thing to do this week. Write down who would actually run a marketing plan if someone handed you one tomorrow. If the answer is a name, you're ready to shop. If it's a shrug, start there.
Last: if $1,200 a month would strain the business, you're too early for any of this. Our free Budget Calculator will give you a defensible number to grow into. No email required.
Questions people ask next
Is a fractional CMO worth it for a small business?
Usually, once you're past roughly $500K in revenue and marketing has outgrown guesswork. Before product-market fit, no. At that stage a plan you run yourself beats any retainer, including ours.
How many hours does a fractional CMO work?
It's part-time. That's enough to own the strategy and direct whoever executes. It is not enough to also do the hands-on work, so ask how execution gets staffed before you sign anything.
What does a fractional CMO actually do?
They own your marketing outcomes part-time: positioning, the plan, channel priorities, budget, and oversight of the people doing the work. A consultant advises and leaves. A fractional CMO is accountable for whether the number moves.
How much does a full-time CMO cost compared to a fractional one?
A full-time CMO runs well into six figures before benefits, and published guides put fractional work at a fraction of that. For most small businesses the real comparison is fractional versus nobody owning marketing at all.
What do Carson Poore Consulting's fractional CMO retainers cost?
$1,200, $2,400, or $4,800 a month, published on our pricing page, with a $3,000 one-time strategy engagement as the usual starting point. 3 months minimum, then month to month. We cap the practice at 8 clients at a time.
