Fractional vs. full-time CFO: the real math
By James Richardson · Co-Founder · July 18, 2026
A full-time CFO costs $150,000 to $300,000 a year, before benefits. Fractional starts at $2,500 a month.
But cost isn't the reason to choose fractional. Utilization is.
The honest comparison
You don't need forty hours a week of CFO thinking. Almost nobody at $1M–$20M does.
You need eight hours a month of the right thinking — at the moment it actually matters. The rest of a full-time CFO's week, in an organization your size, is spent on work that a controller, a bookkeeper, or a system should be doing.
So the question isn't "can I afford a CFO." It's "what am I actually buying forty hours of."
What the full-time number really is
Salary is the smallest part.
- Salary: $150,000–$300,000
- Benefits and employment costs: typically another meaningful fraction on top
- Recruiting: a real cost and a real timeline
- The risk of hiring wrong: the expensive one
That last one is the one nobody prices. A CFO who isn't right for the stage of business you're in is not neutral — they're a year of decisions you have to unwind, and a separation you have to manage.
Fractional isn't a compromise
That's the framing people bring to it, and it's wrong.
Fractional is the same expertise, deployed where it changes the outcome. The judgment that matters in a $5M business happens at a handful of moments a year: the hire you can't unwind, the program you should close, the buyer's first question, the quarter where cash gets tight.
You want the best available judgment at those moments. You don't need it on Tuesday afternoons.
When full-time is genuinely the right answer
We'll say this plainly because it's true, and because we'd rather you hear it from us:
Hire full-time when the complexity is constant, not episodic. Multiple entities with real inter-company activity. A finance team that needs daily management. Continuous capital markets activity. Transaction volume that requires a controller function you don't have.
Hire full-time when you're past the range. Above roughly $20M, the argument shifts. Not always — but usually.
Hire full-time when the CFO's job is mostly managing people. That's not a fractional role. That's a leadership seat.
The decision rule
Here's the one worth writing down:
If a wrong financial decision would cost you more than the advice, you're ready for a CFO. If the CFO's work would fill a week, every week, you're ready for a full-time one.
Most organizations between $1M and $20M are in the first sentence and think they're in the second.
What you should actually ask
Not "how much does it cost." Ask:
- What do I get, and when? If they can't tell you the reporting date, they don't have a process.
- Who's actually in the room? A named person, or an account manager?
- What happens if I'm not a fit? A firm that has never turned business away will not turn you away either.
- What does it cost? If they won't tell you before a call, ask yourself why.
