It's usually one of the first questions a business owner asks, and one of the hardest to get a straight answer to — because "virtual CFO" covers a wide range of scope and seniority, and the price moves with both. Understanding what actually drives the number matters more than the number itself. It's what lets an owner tell a fair quote from an inflated one, and a cheap one from a genuinely underpowered one.
What the price actually reflects
Three things move the cost more than anything else. Seniority — genuine CFO-level experience, built across multiple businesses and a few economic cycles, costs more than a senior bookkeeper or a part-qualified accountant operating under a CFO title, and the gap in judgement shows up exactly when it matters most. Scope — a retainer covering board packs and lender reporting only is priced differently to one that extends into strategy, capital raising support and hands-on execution inside the business. And cadence — a handful of fixed hours each month costs less than genuine on-call availability for the weeks something urgent actually happens, which is rarely spread evenly across the calendar.
Most engagements in the Australian market are structured one of three ways: a fixed monthly retainer for an agreed scope of work, a day-rate or hourly arrangement billed as work is done, or a hybrid that combines a base retainer with additional hours for larger pieces of work. Retainers are easier to budget against. Day rates flex better for a business whose needs vary month to month, but they're harder to predict in a lean one. Neither structure is inherently better — it depends on how predictable the business's own workload actually is.
The comparison that actually matters
The number worth anchoring against isn't a competitor's rate card — it's the fully-loaded cost of the alternative. A full-time CFO hire in Sydney carries a base salary, superannuation, leave entitlements, on-costs and recruitment risk on top of whatever the salary figure suggests, and it's a fixed cost whether or not the business has a CFO-sized problem to solve that particular quarter. A virtual CFO arrangement is priced to flex with what the business actually needs, which is usually the entire point of choosing one in the first place.
The more useful question than "what does it cost" is "what does it cost relative to the decisions it's informing." A CFO-level view on a pricing decision, a lending negotiation or a growth investment can move outcomes worth many multiples of a monthly retainer — and a business without that view often doesn't find out what it cost them until well after the decision's been made. Mentec's own model departs from a straightforward fee for exactly this reason: a reduced retainer paired with an equity stake keeps the upfront cost to the business lower, while tying the advisor's own return to the same outcomes the business is paying to achieve. Whatever the structure on offer, the honest way to evaluate cost is against the size of the decisions a genuine CFO-level view actually touches — not against an hourly rate sitting on its own.
