How Much Does a Fractional CAIO Cost? Every Figure, With Its Source
November 7, 2026 · 8 min read · By Brad Strawbridge
The short answer
A fractional CAIO costs roughly $5,000 to $30,000 a month on the open market, and a full-time Chief AI Officer in the US costs a base salary of roughly $280,000 to $650,000 before bonus and equity. Airus retainers run $10,000 to $25,000 per month a month. The right number for you depends on how many days a month you buy, whether the person advises or also builds, and how messy your current AI use is. Every figure below names its source, and where a number is a firm's own price list we say so.
Fractional CAIO monthly rates
Three sources give a consistent picture. A solo fractional CAIO who publishes a detailed cost guide lists the market at about $5,000 to $30,000 a month, covering two days a month up to three days a week, and notes that this typically works out to 20 to 35 percent of the all-in cost of the full-time hire. A staffing firm that recruits fractional CAIOs says engagements typically cost $6,000 to $25,000 a month, with experienced people billing $200 to $450 an hour. A third firm publishes $120,000 to $240,000 a year for 10 to 20 hours a week. The ranges overlap closely, which is a good sign that the middle of the market is real.
| Source | What they publish | Figure |
|---|---|---|
| Oshri Cohen (solo CAIO), market range | Fractional CAIO, two days a month to three days a week | $5,000 to $30,000 a month |
| Frontline Source Group (staffing firm) | Fractional CAIO engagements, typical | $6,000 to $25,000 a month |
| Frontline Source Group | Hourly rate of experienced fractional AI leaders | $200 to $450 an hour |
| FairWinds Strategies (solo CAIO) | Fractional CAIO at 10 to 20 hours a week | $120,000 to $240,000 a year |
| Oshri Cohen, own published tiers | About 1 day, 2 days, and 3 or more days a week | $10,000, $18,000, and $30,000 a month |

Full-time Chief AI Officer cost
A full-time CAIO in the US carries a base salary of roughly $280,000 to $650,000, according to the same published cost guide, with bonus targets commonly running 30 to 60 percent of base and equity on top. That guide puts the all-in annual cost at roughly $400,000 to $900,000, and a recruiter fee commonly adds 25 to 33 percent of first-year cash. FairWinds Strategies publishes a narrower range for a full-time CAIO of $300,000 to $500,000 a year. The sources differ on scope, which is why you should compare ranges, not single numbers.

Fractional vs full-time, side by side
Putting the two shapes next to each other shows why most businesses under about $50 million in revenue start fractional. The yearly cost of a fractional seat at the published monthly ranges is $60,000 to $360,000. That is arithmetic on the monthly range above, not a separate published figure.
| Fractional CAIO | Full-time CAIO | |
|---|---|---|
| Yearly cost | $60,000 to $360,000 (monthly range times 12) | $400,000 to $900,000 all-in, per one published guide |
| Recruiting | None to a placement fee, depending on how you find them | 25 to 33 percent of first-year cash |
| Time to start | Days to weeks | A search that commonly runs four to eight months |
| Flexibility | Scale up during a push and down after | Fixed headcount |
What AI builds cost on top of the CAIO
A CAIO decides what to build. Someone still has to build it and run it. One published cost guide puts small-business AI agent builds at $5,000 to $25,000 upfront plus $1,000 to $3,000 a month to run, and custom builds at $25,000 to $75,000. Treat these as a market guide from a single source, not a quote. The point to take away is that a retainer is not the whole bill: a realistic first-year AI budget includes the leadership, the build, and the monthly cost to keep it running.

Why quotes vary so much
Six things explain nearly all of the spread between a low and a high quote. Days per month is the biggest lever: two days a month is advice, two days a week is ownership. Advice versus build matters because the same person designing and shipping systems costs more than one who only advises. Regulatory load adds work when you handle health data or sell into the EU. The state of your current AI use matters, because three approved tools is a different job from forty systems nobody has listed. Whether you hire a firm or an individual changes the price, since firms add account management and margin. And a person who holds both the CAIO and CTO seats can price the pair below two separate hires.
What Airus charges
Our retainers are Advisory at $10,000 a month, Embedded at $15,000 a month, Executive at $25,000 a month, with a 6-month minimum and 30 days written notice to end. We also offer a fixed-fee diagnostic for $2,500 that shows where you are losing revenue, with all the arithmetic. If you sign a build within 30 days of the report, the fee is credited toward it. Software and tool subscriptions are billed to you directly, and builds are quoted as a fixed price after the diagnostic.
How to avoid overpaying
Start with the cheapest thing that produces a real answer: a diagnostic with a fixed price and a written result you keep. Ask every candidate for the price in writing before the first call is booked. Ask what is included and what is billed separately, such as software, model usage, and audit fees. And ask what will still be running when the engagement ends. A lower monthly rate is not a better deal if the work walks out the door with the consultant.
