Fractional CFO vs. full-time hire: the real cost math.

Most founders reach this question at the same moment: the books are clean, the business is growing, and nobody can say with confidence what next quarter’s cash looks like. The bookkeeper closes the month; nobody owns the forecast. The instinct is to hire a CFO. The question worth answering first is whether you need the seat or the output.

What a full-time CFO actually costs

A senior finance hire in the US or Western Europe runs $200k+ a year in base salary. That is the headline, not the total. Add payroll taxes, benefits, and bonus, and the loaded cost climbs well past it. Add equity for anyone senior enough to be worth hiring, and you are handing over a slice of the company. Then add ramp: the first three to six months are spent learning your business before the output improves any decision.

For a company between $1M and $20M in revenue, that is a lot of fixed cost to carry for a role that, at your stage, is not yet a full-time job. The work is real. The headcount is premature.

What you are actually buying

Strip the title away and a CFO’s value at your stage is a short list of concrete artefacts: a forecast you trust, a model that shows what happens to cash under the decisions you are weighing, monthly reporting that explains variance in plain language, and someone to think through hiring, pricing, and funding with. None of those require a permanent seat. They require the skill, applied to your numbers, on a defined cadence.

When fractional fits, and when it doesn’t

Fractional works when the decisions are periodic rather than constant: a raise, a pricing change, an expansion, a monthly close that needs interpreting. It stops fitting when finance becomes a daily operational load with a team to manage. Most companies hit the full-time threshold later than they think, often past $20–30M in revenue or once a finance team of two or three exists to lead.

The honest version: if you cannot yet keep a full-time CFO busy with work only a CFO can do, you are buying availability you will not use. Fractional buys the output without the idle cost.

The cost math, plainly

A full-time hire is a fixed annual commitment before the first forecast lands. A fixed-fee engagement is scoped to a question and priced against the answer. A Financial Diagnostic starts at from $2,500 and tells you where the business makes and loses money. A Fractional FP&A retainer runs from $3,000 a month for the ongoing reporting and forecasting a finance function delivers, cancellable on 30 days’ notice. Against $200k+ a year plus benefits and equity, the comparison is not close until the workload genuinely fills the seat.

I give growing businesses the financial visibility of a CFO at a fraction of the cost: models, forecasts, and analysis that turn clean books into confident decisions.
