Fractional CAIO vs full-time hire: cost calculator
Before you open a headcount for a Chief AI Officer, it is worth knowing what that seat actually costs once you add employer on-costs, executive search fees, and the months of ramp before a new hire is fully effective. This calculator lays the fully-loaded year-one cost of a full-time CAIO next to a fractional engagement, so you can see the delta in the currency you budget in. Adjust every assumption — the defaults reflect the European mid-market range for a senior AI executive.
- Year-one fully-loaded cost, not just base salary — on-costs, search fee, and ramp included.
- Sensible EU mid-market defaults for a senior AI executive; every input is adjustable.
- Euro figures formatted for your locale, recomputed live as you type.

A fractional CAIO is part-time by design — you trade day-to-day availability for senior judgement at a fraction of the cost. It fits companies that need the strategy now but cannot yet justify a full-time seat.

- How much does a fractional CAIO cost compared to a full-time hire?
- On the default assumptions here — a €140,000 base with 30% on-costs, a 22% search fee, and four months of ramp — a full-time CAIO lands near €244,000 in year one, while a 4-day-a-month fractional engagement at €1,800/day runs about €86,000 for twelve months. The exact delta depends on your salary band, location, and how many days a month you actually need.
- What is a fractional CAIO?
- A fractional Chief AI Officer is a senior AI leader who works with you part-time — typically a few days a month on a retainer — instead of joining full-time. You get board-level AI strategy, governance, and EU AI Act readiness without carrying a full executive salary and its on-costs.
- When does a fractional CAIO make more sense than a full-time hire?
- When you need senior AI judgement now but cannot yet justify — or afford — a permanent executive seat. Fractional fits companies in the 50–500 employee range that want to set direction, stand up governance, and build internal capability before committing to a full-time hire.
