A full-time CFO costs €150,000–€280,000+ per year all-in once you add employer taxes, benefits, and ramp time, plus a one-time recruitment fee of €25,000–€50,000. A fractional CFO costs €2,500–€12,000 per month depending on scope — typically €36,000–€100,000 per year — with no recruitment, employer taxes, or termination costs. The fractional model usually makes more sense below €10M–€15M in revenue; a full-time hire starts to pay off once you have a finance team of three or more to manage, complex multi-entity operations, or Series B+ investors who expect one.
The question comes up regularly: at what point does it make more sense to hire a full-time CFO than to continue with a fractional one? It's a reasonable question, and the honest answer is more nuanced than most CFO-related content lets on.
This post breaks down the real all-in costs of both options, what you actually get for your money, and the signals that tell you which is right for your business at its current stage. If you are still deciding whether you need a CFO at all, start with the 10 signs you've outgrown DIY finance.
The Full-Time CFO: What It Actually Costs
The headline salary is rarely the full picture. Here's what a full-time CFO hire actually costs in a €5M–€15M revenue business:
Base salary: €100,000–€180,000 depending on experience, sector, and geography. For a genuine CFO (not a experienced accountant with a CFO title), you're typically at the higher end of this range in Western Europe.
Employer taxes and social contributions: Typically 15–30% on top of salary depending on country. In many EU jurisdictions, this adds €20,000–€50,000 per year.
Benefits: Health insurance, pension contributions, and any other employer-provided benefits add €5,000–€15,000 per year.
Recruitment: A CFO hire through an executive search firm will cost 20–30% of first-year base salary — commonly €25,000–€50,000. You also lose significant management time in the hiring process.
Onboarding and ramp time: A new CFO typically takes 3–6 months to become fully productive in your business. You're paying full salary for a partial output during this period.
Total all-in annual cost: €150,000–€280,000+, not including the one-time recruitment cost.
This is the budget impact of a full-time CFO hire at a business of this size. It's also a permanent fixed cost. If the business hits a difficult period, you can't dial it down.
The Fractional CFO: What It Actually Costs
Fractional CFO engagements are typically structured as a monthly retainer based on the number of days or hours per month. A typical engagement looks like:
Early-stage / founder-led business (€0–€3M revenue): 2–4 days per month covering core FP&A, cash flow management, and investor reporting. Cost: €2,500–€4,500/month, or €30,000–€54,000/year.
Growth-stage business (€3M–€10M revenue): 4–6 days per month covering full financial leadership, board pack, management accounts, forecasting, and strategic finance. Cost: €4,000–€7,000/month, or €48,000–€84,000/year.
Larger business or M&A preparation (€10M+): 6–10 days per month. Cost: €6,000–€12,000/month.
Total annual cost for a typical engagement: €36,000–€100,000 depending on scope and stage — with no recruitment cost, no employer taxes, no benefits, no ramp time, and no termination cost.
Capability Comparison: What You Actually Get
This is where the conversation gets more nuanced than the cost comparison alone.
What a fractional CFO typically does well:
- Financial strategy, forecasting, and scenario planning
- Board and investor reporting
- Cash flow management and working capital optimisation
- Management accounts and KPI design
- Fundraising support and M&A preparation
- Bringing executive-level financial judgement without a full-time headcount
What a fractional CFO typically does not cover:
- Day-to-day transactional finance (accounts payable/receivable, payroll processing)
- Management of a large internal finance team
- Being present in the business daily for operational decisions
- Deep technical accounting for complex multi-entity consolidations (without additional support)
What a full-time CFO adds that a fractional one can't:
- Daily presence and availability for reactive decisions
- Direct management of the internal finance team
- Greater institutional knowledge and context over time
- Ability to lead large, complex finance transformation programmes
The right framing is not "which is better" but "which matches what the business needs right now."
The Efficiency Argument: Quality of Hours
There's an uncomfortable truth about full-time CFO hires at smaller businesses: in a €5M revenue company, a full-time CFO spends a large part of their time doing work that should sit in the finance team below them — because the team isn't large enough to support them fully. You end up paying CFO rates for controller-level output.
A fractional CFO brings genuinely CFO-level thinking for the specific hours engaged, with a clear mandate, no internal politics, and no time wasted on activities beneath their capability level. For businesses where the work genuinely demands 2–6 days per month of strategic finance input, a fractional CFO delivers more value-per-pound than a full-time hire.
When to Move to a Full-Time CFO
The signals that suggest a business is ready — or needs — a full-time CFO:
Finance team size: Once you have three or more people in the finance function who need direct daily management, a full-time CFO typically makes more sense than a fractional one.
Transaction complexity: If you're managing complex multi-currency consolidations, debt covenants with frequent reporting requirements, or post-acquisition integration of multiple entities, the daily presence of a full-time CFO starts to justify the cost.
Fundraise or IPO preparation: Institutional investors at Series B and beyond typically expect a full-time CFO. This is less about capability and more about investor confidence in the finance function's depth.
Revenue and complexity threshold: A rough heuristic — once a business reaches €10M–€15M in revenue with a growing finance team and complex financial operations, the math of a full-time hire often starts to make sense, depending on how much you need the CFO present versus strategic.
Board or investor expectation: Some investors, particularly PE-backed businesses, will require a full-time CFO as a condition of investment or as part of the value-creation plan.
The Hybrid Model
Worth noting: many businesses use both. A fractional CFO is engaged for strategy, board reporting, forecasting, and financial leadership. A Finance Manager or Financial Controller handles the day-to-day team management and operational finance. This combination covers all the functional requirements of a full-time CFO at a materially lower total cost — while maintaining strategic quality at the top.
Frequently Asked Questions
Is a fractional CFO the same as an outsourced finance director? Largely yes, though the terminology varies. Fractional CFO, part-time CFO, outsourced FD, and virtual CFO are all used to describe broadly the same model — a experienced financial professional who works for multiple clients simultaneously rather than one employer full-time.
Can a fractional CFO grow into a full-time role? Yes, and this is a natural transition path. Fractional engagements often evolve into more intensive arrangements as the business grows. The advantage is that by the time a business needs a full-time CFO, the fractional CFO already knows the business deeply — the transition has low friction.
How do I know what scope I need? A good starting point is to list the specific financial outputs you need monthly: management accounts, board pack, cash flow forecast, budget, investor reporting. Then work backwards from the time those tasks require. Most businesses are surprised to find the actual demand is 3–5 days per month, not the 20 days a full-time hire would occupy.
