What is a Part-Time CFO?
A part-time CFO is an experienced Chief Financial Officer who works with companies on a reduced schedule, typically 1-3 days per week.
Unlike a full-time CFO, a part-time finance director provides senior financial leadership without the commitment or cost of a permanent executive hire.
The part-time CFO model has grown 250% since 2020, driven by SMEs, startups, and PE-backed companies recognising they can access CFO-level expertise at a fraction of full-time cost.
UK Market Context: According to ICAEW, 45% of growing UK SMEs now use part-time finance leadership. As BBC reports, fractional executive work is transforming how companies access senior talent.
Whether called a part-time CFO, fractional CFO, or portfolio finance director, these roles provide strategic financial guidance, board-level reporting, fundraising support, and financial systems implementation on a flexible basis.
Part-Time CFO vs Fractional CFO vs Interim CFO
Understanding the differences between engagement types helps companies choose the right model for their needs.
| Factor | Part-Time CFO | Fractional CFO | Interim CFO |
|---|---|---|---|
| Schedule | 1-3 days/week ongoing | 1-3 days/week, flexible | Full-time (5 days) |
| Duration | 12+ months typical | 6-24 months | 3-12 months |
| Annual Cost | £50,000-£150,000 | £50,000-£180,000 | £200,000-£400,000 |
| Best For | SMEs, ongoing support | Growing companies | Vacancy, M&A, turnaround |
The terms "part-time CFO" and "fractional CFO" are often used interchangeably. "Part-time CFO" emphasizes the reduced hours on a set schedule, while "fractional CFO" emphasizes working across multiple clients.
