How Much Does a Fractional CMO Cost?

Short answer: most fractional CMO engagements run $4,000 to $20,000 per month, depending on how involved the role is. Hourly arrangements typically land between $200 and $450 an hour, and day rates between $1,500 and $3,500. Where you fall comes down to scope, your stage, and how much of the marketing your fractional CMO is expected to own.

Here’s how to think about it—and how to know whether it’s worth it for your business.

What you’re actually paying for

A full-time CMO costs $250,000 to $450,000+ in total compensation once you add salary, bonus, benefits, and equity. A fractional CMO gives you that same executive-level leadership—strategy, accountability, and marketing that ties back to revenue—for a fraction of the cost, because you’re paying for a slice of their time, not all of it.

A good rule of thumb: your fractional CMO budget should be roughly 20–30% of your monthly marketing spend. Leadership should be proportional to what you’re executing. If you’re spending $30K/month on campaigns and ad spend with no one steering, that’s exactly the money being wasted.

What drives the price up or down

• Scope of involvement. One strategy call a week costs far less than a fully embedded executive leading meetings, vendors, and your team.
• Your stage and complexity. A $1M company needs less than a $30M company with multiple channels and a marketing team to lead.
• How much they own. Advisory-only is cheaper than owning the outcome end-to-end.
• Execution. Strategy and execution are usually billed separately—a fractional CMO leads; a team (in-house or a partner like SWiM) builds.

How Thunder Stock structures it

Rather than one flat number, I offer tiers so you only pay for the level of leadership you actually need:

• On-Call fCMO—weekly strategic guidance for solopreneurs and owners doing $250K–$1M, spending $4K–$10K/month on marketing. You (or your team) execute; I keep you focused.
• Engaged fCMO—fully embedded executive leadership for $10M–$40M companies spending $50K+/month. I own strategy, lead vendors, and collaborate across your team.
• SWiM execution—when you need the strategy built, my execution partner handles funnels, CRM, automation, and creative, billed separately from the fCMO retainer.

Is a fractional CMO worth it?

It’s worth it when marketing is costing you more than it’s making—when you’re spending real money with no one accountable for the return, when you’re running marketing instead of running your company, or when you can’t tell which campaigns actually work. If that’s you, the right fractional CMO pays for themselves by killing what’s wasteful and doubling down on what drives profit.
