The math on a fractional CIO looks simple on the surface: pay a fraction of a full-time salary, get a fraction of the expertise. Chris McGlasson, fractional CIO and founder of ClearStack Advisory, sees that framing miss the actual value equation constantly. The real comparison isn't cost per hour. It's what a $10M-$20M company gets access to that it couldn't otherwise afford, and what it's currently losing by not having that expertise in the room.
What a fractional CIO typically costs
For a company in the $10M-$20M revenue range, fractional CIO engagements generally run $8,000-$15,000 per month, depending on scope and time commitment. That typically covers somewhere between two and four days a week of strategic involvement, not full-time presence.
What a full-time CIO costs by comparison
A full-time CIO at this company size, including base salary, bonus, benefits, and equity where applicable, typically runs $250,000-$400,000+ annually in total compensation. That's before factoring in recruiting costs, onboarding time, and the risk of a bad hire in a role this senior. A fractional engagement at $10,000 a month annualizes to $120,000, roughly a third of the low end of that range, for a role most $10M-$20M companies can't otherwise justify as a full-time seat.
Where the cost comparison misleads
Comparing hourly or monthly rates alone misses what actually drives value in this role. Three factors matter more than the raw number:
Breadth of exposure. A fractional CIO working across multiple companies brings pattern recognition a single full-time hire, however talented, doesn't have access to. Chris McGlasson has seen the same MSP contract structure, the same underinvestment pattern, and the same security gap across dozens of companies this size. That repetition is what makes the advice sharp.
Speed to value. A full-time hire spends months learning the business before producing much strategic output. A fractional CIO experienced with this revenue range typically identifies the highest-leverage problems in the first 30-60 days, because the patterns are familiar even when the company isn't.
Flexibility to scale up or down. IT strategy needs aren't constant. A company mid-migration or mid-acquisition needs more hands-on involvement than one in a steady state. A fractional arrangement can flex with that need. A full-time salary doesn't shrink when the workload does.
Where the value actually shows up
The clearest ROI isn't a single number, it shows up across several categories that compound over a year:
- Vendor and contract renegotiation. Reviewing MSP contracts, software licensing, and infrastructure spend with an outside, informed eye frequently recovers 10-15% in overspend within the first few months.
- Risk reduction. Catching a security gap or compliance exposure before it becomes an incident is worth more than the entire annual engagement cost in a single avoided event.
- Decision speed. Having someone in the room who can evaluate a major technology decision, an ERP switch, an AI tool rollout, a cloud migration, without spending months getting up to speed shortens the timeline from question to confident decision.
- Governance that doesn't exist otherwise. Companies at this size rarely have anyone whose job is exclusively to think about IT strategy. That gap tends to get filled by whichever vendor is in the room, which produces a roadmap shaped by the vendor's interests rather than the company's.
When a fractional CIO makes sense, and when it doesn't
A fractional CIO is generally the right fit for a company that's outgrown ad hoc IT decision-making but doesn't yet have the complexity or budget to justify a full-time executive seat. Companies that already have strong internal IT leadership, or that are large enough to need daily executive presence on technology decisions, typically get more value from a full-time hire. The $10M-$20M range is where the fractional model tends to fit best: enough complexity to need strategic oversight, not enough to fill a full-time role with strategic work alone.
