Fractional CFO vs. Full-Time CFO: What to Actually Choose Most businesses that hire a full-time CFO didn't need one. They needed a fractional CFO and didn't know it was an option. The full-time CFO is a prestige hire. You get a title on the org chart, a salary in the offer letter, and the confidence of having a real executive in the finance seat. What you also get is a $200,000+ per year commitment for a role most businesses under $20M in revenue don't actually need full time. Here's the honest comparison: what each costs, what you actually get, and which one is right for where you are right now. Full-Time CFO: The Real Cost The salary range varies by market and stage, but the numbers are consistent: Early-stage startup: $150,000 to $200,000 base salary. Growth-stage ($10M-$50M): $200,000 to $350,000 base. Add 20-30% for benefits, payroll taxes, and employer costs. Add recruiting fees if you use a search firm: typically 20-25% of first-year compensation. Add equity if the candidate expects it, which most senior finance executives do. At the low end, a full-time CFO costs you $180,000 to $220,000 per year in fully loaded compensation. At the high end, you're looking at $400,000 or more. That's before you factor in the 3-6 months to recruit, onboard, and ramp someone—before they're fully productive. Fractional CFO: The Actual Cost A fractional CFO is a senior finance executive working part-time—typically 10 to 20 hours per month—at a fraction of the full-time cost. Entry-level fractional: $1,500 to $3,000 per month. Mid-tier: $3,000 to $6,000 per month. Senior: $6,000 to $15,000 per month. At mid-tier—where most growing businesses land—you're spending $36,000 to $72,000 per year. Against a full-time CFO's $200,000 minimum, that's a savings of $130,000 to $165,000 annually.

One client described the experience: "Nimbl has been an incredible partner, navigating the negotiation, audit, and diligence process brilliantly." What You Get With Full-Time: Embeddedness A full-time CFO is fully embedded. They're in every leadership meeting. They own the finance function completely. They're available whenever you need them, building institutional knowledge continuously. That depth matters in specific situations: You're raising a significant venture round and need someone managing the process full-time. You're preparing for acquisition or IPO and need a CFO...
