The demo above builds a real campaign plan in about 30 seconds, no card required. Relevant here because the execution gap below is exactly what it fills.
A fractional CMO in the US costs $8,000 to $22,000 a month on a retainer, and $12,000 to $15,000 is the usual band for two to three days a week. Bought by the hour it is $200 to $450, and by the day $1,500 to $3,500. The number almost every quote leaves out is that a fractional CMO leads marketing rather than producing it, so the real cost of the engagement is the retainer plus whoever builds the campaigns. Rate figures checked against the US fractional marketplaces on 22 September 2026.
That last sentence is the whole buying decision, and it is why some companies get enormous value from a fractional CMO and others cancel in month four feeling like they paid $36,000 for a slide deck. The difference is not the quality of the person. It is whether there was anyone to lead.
Fractional CMO rates, by how you buy the time
Rates vary less than the marketing suggests. What changes is the unit you buy them in, and the unit is what decides your monthly bill.
| How you buy it | US price | What it suits |
|---|---|---|
| Hourly advisory | $200 to $450 an hour | A defined question: pricing, positioning, a channel decision. Most expensive per unit of work. |
| Day rate | $1,500 to $3,500 a day | Workshops, planning offsites, a quarterly strategy reset. |
| Retainer, about one day a week | Roughly $5,000 to $8,000 a month | A founder who needs a sounding board and a quarterly plan, not daily management. |
| Retainer, two to three days a week | $12,000 to $15,000 a month typical | A company with a marketing team or agency that needs someone accountable for the number. |
| Full published range | $8,000 to $22,000 a month | The spread across seniority, industry and scope reported by US fractional marketplaces. |
Two details are worth pulling out of that table before you compare quotes. First, hours are almost never standardized. CMOx describes an $8,000 retainer covering 40 hours a month, which works out at $200 an hour, but plenty of $10,000 retainers cover 20. Get the hours written down, because otherwise you are comparing two numbers that measure different things.
Second, seniority is priced honestly in this market. An operator who has run marketing at a company the size of yours, in your category, costs near the top of the band, and the gap between that person and a generalist at $6,000 is usually visible inside a quarter. If budget forces you to the bottom of the range, you are often better served buying fewer hours from the better operator than more hours from the cheaper one.
What a fractional CMO retainer does not include
Here is the line item that turns a $12,000 quote into a $20,000 month. A fractional CMO sets direction and holds people accountable to it. Production is a separate budget, and in most engagements it is the larger one.
| Work | In the retainer | What you pay for separately |
|---|---|---|
| Positioning and messaging strategy | Included | Nothing. This is the core of what you are buying. |
| Channel plan and budget allocation | Included | Nothing. |
| Managing an existing team or agency | Included | The team or agency itself. |
| Board and investor reporting on marketing | Included | Nothing. |
| Writing ads, emails, posts and landing pages | Rarely | A copywriter, an agency retainer or software. |
| Design and ad creative | No | A designer at $60 to $120 an hour, or a creative tool. |
| Building and launching campaigns in the ad accounts | No | A media buyer, an agency or automation software. |
| Email sending, CRM, analytics and reporting tools | No | Your own software stack, commonly $150 to $800 a month. |
| Media spend | No | Whatever you put behind the plan. |
Run the arithmetic for a company with no marketing hires. A $12,000 retainer, a freelance copywriter and designer at $4,000 to $8,000 a month between them, and $200 to $800 of software comes to $16,000 to $21,000 a month before a single dollar goes to media. Over a year that is $192,000 to $252,000, which is the loaded cost of a full-time CMO, except spread across three relationships and with nobody there full time.
CMOx is straightforward about the condition that makes the math work: the recommendation of a $7,000 to $9,000 monthly allocation is aimed at "smaller companies with dedicated marketing departments". The department is the point. A fractional CMO multiplies a team. With no team, the multiplication has nothing to act on.
If you are trying to work out honestly whether the gap is direction or output, a structured assessment of where your operation actually stands across process, skills and tooling will tell you faster than a discovery call with someone whose product is the retainer.
Fractional CMO cost against a full-time CMO salary
Every article in this category tells you a fractional CMO saves 50 to 90 percent versus a full-time hire. That claim is close to meaningless, because the benchmarks it rests on disagree by more than $200,000. Here is what the US salary sources reported when checked on 22 September 2026.
- ZipRecruiter: $160,891 average
- Indeed: $171,067 average
- PayScale: $189,969 average base
- Built In: $293,575 average total compensation
- Glassdoor: $307,400
- Salary.com: $373,953
Pick ZipRecruiter and a $12,000 retainer looks like a poor deal. Pick Salary.com and the same retainer looks like a 60 percent saving. Neither calculation tells you anything about your company, because the spread reflects which companies each source samples, not what a CMO is worth.
Do this instead. Write down the salary you would actually offer for the level of person you would actually hire, add 28 to 35 percent for payroll taxes, benefits and equipment, and divide by twelve. That is your real full-time monthly number. Then compare it with a retainer plus the production budget from the section above, so you are comparing two complete costs rather than one complete cost against a partial one.
| Option | Monthly cost | What you actually get | Who it fits |
|---|---|---|---|
| Full-time CMO | $22,000 to $27,000 a month loaded | One senior leader, full attention, plus benefits, equity and notice periods. | Companies past roughly $20M in revenue with a marketing department to lead. |
| Fractional CMO | $8,000 to $22,000 a month | Senior direction for one to three days a week. No benefits, no equity, cancellable. | Companies with people already producing marketing and nobody steering them. |
| Agency of record | $4,000 to $15,000 a month plus media | Strategy and production together, but the senior name on the pitch is rarely the person doing the work. | Companies that want output and direction from one contract and can live with shared attention. |
| AI CMO software plus advisor hours | $149 a month plus a few hundred a quarter | The software plans, writes and launches campaigns on your approval. You buy senior judgment by the hour when a real decision comes up. | Founders and marketers of one whose bottleneck is that campaigns never get built. |
Three budgets, and what to buy in each
Under $5,000 a month of total marketing budget. Do not buy leadership. A $5,000 retainer would be your entire budget, and the plan it produces would sit unbuilt. Buy output: software that writes and launches campaigns, plus whatever media you can defend. The strategy at this size is usually not the hard part, because the founder already knows who buys and why. The hard part is that nothing ships in a week where the founder is busy.
$5,000 to $20,000 a month. This is the band where the hybrid wins. Put the bulk into production and media, run the campaigns through AI CMO software, and buy four to eight hours of senior advisory time a quarter at $200 to $450 an hour to pressure-test the plan. That is $1,600 to $3,600 a year of senior judgment against $96,000 or more for a retainer, and for most companies at this size the judgment was never the constraint.
Over $20,000 a month, with people already producing. Now a fractional CMO earns the fee. There is a team to direct, enough spend that a 15 percent efficiency gain covers the retainer, and real strategic choices with money attached. Hire at the top of the range, insist on written hours, and give the team software so the direction turns into campaigns quickly.

Questions buyers ask before signing a fractional CMO contract
How much does a fractional CMO cost?
In the US a fractional CMO costs $8,000 to $22,000 a month on a retainer, with $12,000 to $15,000 typical for two to three days a week of senior time. Hourly advisory work runs $200 to $450 an hour and day rates $1,500 to $3,500. Those figures buy leadership, not production, so budget an execution line on top.
What is the hourly rate for a fractional CMO?
Published hourly rates cluster between $200 and $450. CMOx puts the band at $200 to $350 an hour, and Fractionus quotes up to $450 for operators with a larger track record. Hourly is the most expensive way to buy the time per unit of work, which is why most engagements convert to a monthly retainer inside a quarter.
How many hours a month does a fractional CMO actually work?
A typical retainer covers 20 to 40 hours a month, which is one to two days a week. CMOx works an $8,000 retainer at 40 hours, roughly $200 an hour. Always get the hours written into the contract, because two quotes at $10,000 can differ by a factor of two in the time you actually receive.
Is a fractional CMO worth it for a small business?
It is worth it when you already have people or an agency producing marketing and nobody senior is steering them. It is poor value when nobody is producing anything, because the retainer buys direction and there is no one to direct. Under roughly $20,000 a month of total marketing budget, fund output before leadership.
What is the difference between a fractional CMO and a marketing consultant?
A fractional CMO takes an ongoing seat in your leadership team, owns the marketing number and manages whoever executes. A consultant is engaged for a defined deliverable, such as a positioning project or a channel audit, and then leaves. The CMO title costs more per month because it carries accountability, not just advice.
How much does a full-time CMO cost in the US?
Reported averages range from $160,891 at ZipRecruiter to $373,953 at Salary.com, with Built In at $293,575 total compensation. Add 28 to 35 percent for payroll taxes and benefits on whatever base you would actually pay. For most mid-market companies the loaded monthly cost lands between $22,000 and $27,000.
When should you hire a fractional CMO?
Hire one when marketing is already running and the problem is direction: several channels active, a team or agency in place, and no agreement on what to prioritize. Hire production instead when the calendar is empty. A retainer signed before there is anything to lead usually gets cancelled in month four.
The decision in one line
Ask what would happen the week after the fractional CMO delivers the plan. If the answer is that a team picks it up and runs, the retainer is good money. If the answer is that the plan waits for someone to have time, you have an execution problem and a leadership purchase will not fix it. That case is what AI CMO software is for: it produces the campaigns, launches them once you approve, and shifts budget toward what converts, at $49 to $499 a month rather than a retainer. For the wider question of what machines can and cannot take over, can AI replace a marketing team goes through it task by task.
