A plain-English guide to what a fractional CFO does, how the role compares to a full-time CFO, and when each one makes sense.
The same core work as a full-time CFO, sized to your needs. A fractional CFO typically owns:
The difference is the engagement model: instead of a permanent executive on full salary, you bring in senior expertise for the time your company needs — a few days a month, scaling up around events like a fundraise or audit.
| Fractional CFO | Full-time CFO | |
|---|---|---|
| Cost | A fraction of a full salary — you pay for the time you use | $250,000–$350,000+ in salary, plus bonus, equity and benefits |
| Commitment | Flexible, cancellable, scales up or down | Permanent hire with notice periods and severance |
| Time on your business | Days per month, focused on what matters | Full-time, including lower-value work |
| Time to start | Days to weeks | 3–6 month search and onboarding |
| Breadth of experience | Across many companies and sectors | Deep in your single business |
| Best for | $10M–$100M companies that need senior finance leadership but not full-time | Larger or highly complex companies needing a dedicated executive |
A fractional CFO usually makes sense when your company has outgrown a bookkeeper or controller but doesn't yet need — or can't justify — a full-time executive. Common triggers: you're preparing to raise capital, your cash flow needs active management, the board wants better reporting, or finance has become a bottleneck as you scale. A full-time CFO becomes the right move when the role genuinely requires a dedicated, full-time leader — typically at greater size or complexity, or when finance is central to daily operations.
A full-time CFO in this market typically costs $250,000–$350,000+ a year in salary alone, before bonus, equity, benefits and the team around them. A fractional CFO costs a fraction of that because you only pay for the time you use, scoped to your needs. Most credible firms scope fractional pricing in a conversation rather than publishing a fixed rate, because it depends on the hours and complexity involved.
Broadly yes — the terms overlap. "Fractional" emphasises that you use a fraction of a CFO's time on an ongoing basis; "virtual" emphasises remote delivery; "interim" usually means a temporary, full-time CFO covering a gap. The work is the same senior finance leadership.
It varies by engagement — often a few days a month at steady state, scaling up around events like a fundraise, audit or budget cycle. The model is built to flex with your needs.
No. A fractional CFO sits above day-to-day bookkeeping, leading strategy, reporting and decisions. They work with your existing accountant or bookkeeper, not instead of them.
It is a fractional CFO who also transforms your finance function with AI and automation — automating the close, reporting and forecasting — so you get a modern finance stack alongside the leadership, not just advice.
