The Honest Answer First
If you searched this comparison, you're probably picturing two options: hire someone part-time, or hire someone full-time. For a solo owner or a small business, the honest answer is that neither is what you need right now — and most of the content written about this comparison was built for a different audience entirely.
What Full-Time and Traditional Fractional CTOs Actually Cost
Worth knowing, even if neither applies to you yet:
A senior full-time CTO at a funded company typically runs $300,000–$420,000 annually in salary and benefits alone, before equity, plus a 3–6 month hiring process. That number exists because the role is managing an entire engineering department — hiring, architecture, day-to-day leadership of a team of people.
A traditional fractional CTO — the kind most search results describe — is priced as a monthly retainer, typically $3,000–$25,000 a month depending on experience and hours committed, usually structured around 15–30 hours a month of strategic involvement with an existing engineering team.
Both of these exist to solve the same problem: a company with engineers who needs senior technical leadership over that team. If you don't have engineers, neither model is actually pricing what you need — you'd be paying for capacity built for a team that doesn't exist.
What You Actually Need Instead
Most small businesses without an in-house technical team don't need ongoing leadership of anything. They need an answer to a specific question, when it comes up: is this contract fair, is this vendor honest, should we build this or buy it, is this the right tool for what we're trying to do.
That's a fundamentally different shape of engagement — access to judgment when a decision arrives, not a retainer sized for a team you're not managing. It's priced per engagement or per project, not as a monthly commitment, because the value isn't in availability five days a week — it's in getting a straight, technically grounded answer before you commit real money.
When You Might Actually Need One of These Two Models
There's a real point where the traditional comparison starts to apply: the moment you have engineers on staff and are deciding whether their leadership should come from inside or outside the company. That's a genuine fork, and if you get there, the stage-based logic most articles describe — fractional while you're small and growing that team, full-time once you've crossed into daily operational complexity — is reasonable guidance.
For almost every solo owner and small business today, that fork is a long way off, and paying for it now would be paying for a problem you don't have.

Getting the Decision Right
If you're evaluating a contract, a vendor, or a build-vs-buy call right now, that's the actual decision in front of you — not "fractional or full-time."
