Fractional CTO vs full-time: the decision, priced honestly

This article prices all three, gives you the crossover maths, and is upfront about when the fractional model loses. The usual title note applies: people search "fractional CTO", but if your business runs on websites, platforms, and vendors rather than a product codebase, the seat you're actually comparing is a fractional Head of Digital. Here's how to tell the difference. The maths below works for either title.

Option one: hire full-time

A full-time senior digital leader in Australia:

• Base salary: $180K to $280K depending on city, scope, and title inflation
• On-costs: superannuation, leave loading, tools, insurance, roughly 25 to 30 percent on top
• Recruitment: 15 to 20 percent of base for a retained search, plus three to five months of vacancy while it runs
• Ramp: three to six months before the hire is genuinely making the function better rather than learning it
• First-year total: $250K to $400K, all in

And one number nobody budgets: the cost of a mis-hire. Executive hiring has a real failure rate, and unwinding a wrong senior hire takes a year and change once you count the notice period, the re-search, and the second ramp. Risk-adjust the first-year total and the true cost of "just hire someone" is higher than the payslip suggests.

What you get for it, when it works, is the thing fractional can never fully match: forty-plus hours a week of presence, deep context, and a person whose entire career is invested in this one business.

Option two: engage fractional

A standard fractional engagement in the Australian mid-market:

• Four to eight days a month at senior day rates
• $4,500 to $8,000 a month, so $54K to $96K a year
• No on-costs, no recruiter, no ramp you pay for twice. Fractional operators are productive in weeks because diagnosing unfamiliar businesses is the job
• Three-month minimum, quarterly reviews, so the exit cost of a wrong fit is measured in weeks, not years

The full rate breakdown, including what moves engagements up and down the band, is in what fractional digital leadership costs in Australia.

What you give up is availability. A fractional leader is not in the building on Thursday afternoon when a vendor sets something on fire. The model works because most digital functions in the $2M to $50M revenue band don't generate five days a week of genuine leadership decisions. They generate two, plus a lot of execution that shouldn't be done at executive rates anyway.

Option three: nobody owns it

This is the option most businesses are actually running, and it's worth pricing because it feels free.

No owner means platform decisions get made by whoever shouts loudest, usually the incumbent agency. Analytics drift until nobody trusts them. The martech stack accretes subscriptions. Rebuilds stall, then restart, then stall. Vendor spend leaks because nobody on your side of the table is qualified to challenge an estimate.

I've watched that leak get measured. In one client-side role, the first year of simply owning the vendor relationships properly recovered $250K in spend: money that was already budgeted, already being invoiced, and going nowhere. Doing nothing wasn't free. It was the most expensive option on the table.

The crossover maths

The decision reduces to one question: how many days a month of genuine leadership work does this function generate?

Two honest notes on that table. First, "leadership work" means decisions, vendor accountability, and board-facing ownership, not tickets. Businesses routinely mistake ten days of execution backlog for ten days of leadership need, then hire an expensive executive who spends four days a week doing production work. Second, workload is lumpy: a re-platform year can push a business into the hire zone temporarily, which is exactly the kind of peak the fractional model exists to absorb without a permanent salary attached.

When full-time simply wins

Being upfront about the boundary:

• Software is your product. A genuine product business needs a genuine CTO in the building, owning architecture and the engineering team. Fractional product CTOs exist, but that's a bootstrapping bridge, not a steady state.
• You're past roughly $50M revenue with a digital function big enough to have direct reports who themselves need managing every week.
• The function is the turnaround. If digital failure is an existential threat this year, buy all the attention you can afford.
• You need a face in the building. Some leadership cultures run on presence. That's not a flaw, but don't fight it with a two-day-a-month engagement.

When fractional wins

• The function matters but doesn't fill a week
• You need the seniority now, not after a five-month search
• A specific event is driving the need: a re-platform, a vendor reset, a stalled project, a board question
• You want the option to convert: plenty of fractional engagements end by scoping and hiring the full-time role properly, with the fractional leader writing the job description that reflects reality instead of a wish list

That last one is underrated. The most expensive way to define a senior digital role is to guess. Six months of fractional engagement produces a truthful job description, a governed function to hand over, and a hiring decision made from evidence.

Where to from here

If you're weighing this decision with a real budget attached, the worst way to resolve it is a sales conversation with someone who only sells one of the options. The better way is two hours of structured diagnostic against your actual function: what it generates, what it leaks, and how many days a month it genuinely needs. That's what the $750 discovery session is for, and "you should hire full-time" is a result it regularly returns.
