Fractional CMO vs Consultant: Which One Do You Need?

The fractional CMO vs consultant choice comes down to who owns your marketing once the meeting ends. Here's how to tell which one you need, what each costs, and the mistake owners make after they hire.

Hire a fractional CMO when nobody in your company owns marketing. Hire a consultant when someone already does and needs help with a few gaps.

I'm Chris Hornak, co-founder of Swift Growth Marketing. My business partner Wade and I fill the CMO role for companies that don't have one. We consult and plan strategy too. For Speranza Consulting and Investments, a company that develops and runs Goddard Schools, we're essentially their CMOs.

Short answer: A fractional CMO is a part-time marketing leader who sets the strategy, runs the work and reports on results, usually for a set monthly fee. A marketing consultant fills a specific gap for a company that already has a marketing lead. No marketing leader means you need the CMO. A leader with gaps means you need the consultant.

What does a fractional CMO actually do?

A fractional chief marketing officer does the job a full-time CMO would do, for part of the week. "Fractional" refers to their time. The job is the whole job.

Here's what a normal month looks like for us at Speranza:

• We decide what the strategy is.
• We work with their team on topic approval.
• We make the creative: the articles, the social posts, the pages.
• We schedule and plan the execution.
• We report on progress and suggest next steps.

Speranza had no website and no online presence when they came to us. We built their first site from scratch, and now we write two articles a month on topics their team picks, plus social posts they approve first. Nobody at Speranza has to manage a marketing plan.

The strategy is ours. The topics get their sign-off. A fractional CMO leads, but the owner still holds the brand.

Fractional CMO vs consultant: what's the difference?

The difference is ownership. A fractional CMO owns the outcome month after month. A consultant owns a task, and hands it back when it's done.

The two can work together. A fractional CMO can bring in a specialist for one job, like a technical SEO audit, and fold the results into the plan.

When don't you need a fractional CMO?

You don't need one if you already have the role or the department. If a marketing director runs your team and you need a partner to help fill in some gaps, hire the partner for the gaps.

A consultant fits a few other cases too:

• A single project with a clear end, like a website launch or a messaging rewrite
• One skill your team lacks, like paid search or analytics
• An outside read on a plan your team already wrote

A fractional CMO has limits worth naming. They work with more than one company, so they aren't in your office every day. The first weeks go to learning your business, your buyers and your team. If you need someone in every internal meeting, a full-time hire may suit you better, even at the higher cost.

What does a fractional CMO cost?

We charge a set monthly fee, because the work runs every month and the scope stays steady. Consultants more often bill by the project or the hour.

For a sense of what a full-time hire costs, look one level down. The median annual wage for marketing managers was $166,790 in May 2025, per the Bureau of Labor Statistics. A chief marketing officer sits above that role, and salary is only part of the bill once you add benefits and hiring costs.

Turnover adds to it. The average CMO at an S&P 500 company stays 4.1 years, against five years for all C-suite roles, Marketing Week reported from Spencer Stuart's data. A smaller company that hires and loses a CMO pays to search all over again.

That's part of why the fractional model has grown so fast. In 2022, just 2,000 LinkedIn profiles mentioned fractional leadership. By 2024, more than 110,000 did, according to SHRM's look at fractional leaders.

I can't give you one market rate that holds everywhere. Fees swing with scope, how much of the work the CMO's team makes, and how many channels you run. Ask any candidate what the monthly fee includes, in writing, before you compare prices.

The mistake owners make with a fractional CMO

The most common one I see: owners think it'll be completely hands off.

It won't be. You still need some involvement, to make sure the work stays on brand and in line with how your company runs. A fractional CMO doesn't know about the new location you're opening or the service you plan to drop unless you tell them.

At Speranza, that involvement is light. Their team approves the topics and approves the social posts before they go out. That keeps what we publish on brand.

Plan for a short check-in each month, a named person who approves the work, and a clear line on what the CMO can decide alone.

FAQ

Is a fractional CMO worth it for a small business?

It is when nobody owns marketing. You get one person leading the plan and the work for a monthly fee, instead of a full-time salary. If you only need one project done, hire a consultant for that project.

What's the difference between a fractional CMO and an interim CMO?

An interim CMO is a full-time stand-in who covers the role while you hire a permanent one. A fractional CMO works part-time and stays on as long as the arrangement works.

Can a fractional CMO work with our agency?

Yes. Some companies keep their agency for the hands-on work, and the fractional CMO sets the strategy the agency follows. Agree up front on who approves what, so the agency gets one set of directions.

If nobody at your company owns marketing today, that's the job we do. See how our growth marketing services work as your marketing team.
