Fractional CFO vs. Full-Time CFO: The Real Cost Comparison

Owners ask us this constantly: fractional CFO vs full-time CFO — which one actually makes sense for a business our size? The honest answer is a math problem, not a philosophy. A full-time CFO and a fractional CFO do the same core job — cash flow forecasting, KPI reporting, pricing decisions, scenario planning — but the price tags sit in completely different universes until revenue crosses a specific line.

Below are the real 2026 numbers for both, side by side, so you can run your own math instead of guessing.

What a full-time CFO actually costs

Base salary for a full-time CFO at a small-to-midsize company runs $180,000-$280,000, and climbs past $300,000 at venture-backed or multi-entity companies. That's before anything else hits the ledger.

Add payroll taxes, health benefits, and a 401(k) match — typically 20-30% on top of base — and the fully loaded annual cost lands at $216,000-$450,000. Divide by twelve and you're looking at $18,000-$37,500 a month before equity, a signing bonus, or a severance package if it doesn't work out.

Then there's the cost of getting one in the door. Contingency recruiter fees run 20-25% of first-year total comp — commonly $40,000-$70,000 as a one-time hit. The search itself takes three to six months, and once hired, most CFOs need another 60-90 days to actually understand your business before they're operating at full value. You're paying full salary through all of that ramp.

What a fractional CFO actually costs

A fractional CFO's monthly cost scales with revenue and complexity, not with a fixed salary band. Businesses under $1M in revenue typically pay $2,000-$5,000 a month. Between $1M and $5M, the range moves to $5,000-$10,000 a month. Past $5M, or with multiple entities and investors in the mix, it climbs to $10,000-$15,000+ a month.

There's no recruiter fee, no benefits line, no payroll tax burden on your side — you're contracting a service, not employing a person. Most engagements start within one to two weeks of signing, and you can flex hours up during a raise or crunch and back down once things stabilize. That flexibility is the part full-time hiring can't match at any price.

The real monthly comparison

Put them side by side for a $3M agency. A fractional engagement at that size runs roughly $8,000 a month. A full-time CFO at a $220,000 loaded package runs about $18,300 a month. Same deliverables — cash flow forecasts, margin analysis, board-ready reporting — at roughly 44% of the cost.

Run the same comparison at $8M in revenue with a more complex engagement: $13,000 a month fractional against $28,000-$32,000 a month for a full-time hire with a more senior profile and larger package. The fractional model still runs under half the cost, it's just a smaller gap.

When the math flips

Somewhere between $10M and $20M in revenue, the equation changes. Once a business needs daily involvement — sitting in on client calls that touch pricing, managing a finance team, being in the room for board meetings every month instead of quarterly — the hours a fractional CFO can realistically sell you start to cost nearly as much as a salary, because you're buying so many of them.

The same is true ahead of a fundraise or acquisition. If you're heading into due diligence, a full-time finance leader who lives inside the numbers every day is often worth the premium over a fractional arrangement billing 15-20 hours a month.

How to decide which one fits now

Use a simple test. If you're under $10M in revenue, not in an active raise or sale process, and you need roughly 10-20 hours a month of CFO-level thinking rather than a daily presence, fractional wins on cost every time — usually by a factor of two to three. If you're above that threshold, or actively fundraising or preparing for an exit, price out the hours you actually need at a fractional CFO's effective rate — typically $150-$300 an hour — against a full-time salary, and let that number, not a title, make the call.
