A fractional CMO is a senior marketing leader for part of the week; an agency runs channels every month; a full-time CMO leads every day. Choose a fractional CMO for direction without a full-time executive, an agency for execution, a full-time CMO when marketing is large, and pair a fractional CMO with an agency when you need both.
What each does
Leadership, execution, or both:
- Fractional CMO: sets strategy and budget, hires and manages the team and suppliers, reports to leadership, for a set number of days a month.
- Agency: builds and runs campaigns, content, ads and SEO, and reports results.
- Full-time CMO: leads marketing every day as part of the executive team, owning strategy, budget, team and results.
What public figures say about cost
There is no independent public survey of fractional CMO fees that we could find in November 2026; published figures come from firms that sell the service, so we do not quote them. Fractional leaders usually work on a monthly retainer for a set number of days; ask for the days, the deliverables and the notice period.
For the full-time comparison, the Bureau of Labor Statistics puts the median pay for advertising, promotions and marketing managers at $165,780 a year in 2025, and for chief executives at $213,990 in May 2025; neither figure is a CMO salary as such, so use them as reference points. Benefits add 30.0% of compensation on average in private industry, per BLS's June 2026 data. For agencies, Clutch's 2026 pricing guide puts most at $25 to $49 an hour, with channel specialists at $100 to $149.
When a fractional CMO fits
Choose a fractional CMO when:
- You need a marketing strategy, budget and plan owned by someone senior.
- You have a small team or several suppliers who need direction.
- You are preparing for growth, a new market or a funding round.
- You cannot yet justify a full-time executive salary.
When an agency fits
Choose an agency when:
- The plan is set and you need it carried out.
- You need specialists across several channels.
- You want monthly execution and reporting without hiring.
When a full-time CMO fits
Choose a full-time CMO when:
- Marketing has a large budget and team that need a daily leader.
- Marketing decisions are central to the business every week.
- The leadership team and board need a marketing executive in the room.
Fractional CMO and agency together
The most common pairing for growing companies is a fractional CMO who sets and owns the plan and an agency that runs the channels. The CMO briefs and reviews the agency, holds it to the targets and changes course when results say so. The arrangement can grow into a full-time hire later, with the plan and suppliers already in place.
Questions to ask before you choose
Four questions that usually settle it:
- What decisions need a senior marketing leader, and how many days a month?
- Which channels need running, and do we have the people?
- What will we measure, and who reports it?
- What is the notice period, and who owns the plan and accounts if we part?
Conclusion
A fractional CMO leads marketing part-time, an agency executes, and a full-time CMO leads every day. Public figures put marketing managers' median pay at $165,780 a year and chief executives' at $213,990 (BLS, 2025), plus benefits at 30%; agencies mostly charge $25 to $49 an hour on Clutch's data. Choose by the leadership and execution you need now, and pair a fractional CMO with an agency when you need both.
