The difference between a fractional CMO and a full-time CMO comes down to time and cost. A fractional CMO leads your marketing strategy part time for a monthly fee, while a full-time CMO is a permanent executive with a salary, benefits and a recruiting search behind the hire. PSM Marketing provides fractional CMO services for firms that need senior direction without adding an executive.

What a fractional CMO does
A fractional CMO is a senior marketing executive who works with your firm part time. With PSM Marketing, that leader is Terrie Wheeler or Michelle Wheeler, who sets your strategy and directs the people already doing your marketing.
That work includes:
- Strategy: an annual marketing plan and quarterly priorities built on The Four Pillars of Marketing™
- Team direction: goals, priorities and feedback for your internal marketer or team
- Vendor management: one strategy across your web, PR, social media and other vendors
A fractional CMO doesn’t replace your marketing staff. Your staff gets direction, priorities and someone senior to answer to.
What a full-time CMO costs
The Bureau of Labor Statistics doesn’t publish a separate figure for chief marketing officers, but its marketing manager data offers a useful starting point. The national median pay for a marketing manager was $166,790 in May 2025. Benefits make up 30% of total compensation for private industry workers, which brings that cost to about $238,000 a year.
A CMO is a more senior role, so you should expect to pay more than that. You’ll also need to budget for a recruiting search and for the months the role may sit open.
PSM Marketing quotes each fractional CMO engagement for a fixed monthly fee, based on your goals, team and vendors. Engagements run under a 12-month agreement.
When a fractional CMO makes sense
A fractional CMO usually makes sense when you already have people doing marketing, but no one senior deciding what they should do. Three signs point that way:
- You have a marketer, but no marketing leader. A capable coordinator or manager needs direction, priorities and someone to answer to.
- You work with several vendors who don’t talk to each other. Your web firm, PR contact and social media freelancer each do their piece, but nobody connects the pieces to your goals.
- You’re spending on marketing without knowing what it returns. Invoices arrive every month, but no one can say which efforts bring in clients.
When a full-time CMO makes sense
A full-time CMO makes sense for large firms that are ready for a permanent executive. That usually means your firm has enough marketing staff, budget and day-to-day decisions to fill a senior role year-round.
Some firms start with a fractional CMO to build the plan and the team first. If the work grows into a full-time job, your firm will have a clearer picture of the role it needs to hire.
When you need more than a CMO
Both options provide leadership, but someone still has to do the work. If you don’t have marketing staff or vendors, or your staff needs more hands, an outsourced marketing department gives you partner-level strategy and the team that carries it out.
A full department costs $4,000 to $10,000 or more per month. For a full breakdown, read how much outsourced marketing costs and how PSM Marketing engagements work.
