What is a Fractional CFO?
A fractional CFO is an experienced Chief Financial Officer who provides strategic financial leadership to companies on a part-time basis, typically 1-3 days per week. They bring the same expertise as a full-time CFO – fundraising, financial strategy, board reporting – at 50-70% less cost. Fractional CFOs are particularly valuable for SMEs and scale-ups that need sophisticated financial leadership but aren't ready for the £250,000+ investment of a full-time CFO.
How Much Does a Fractional CFO Cost in the UK?
Fractional CFO [day rates](/fractional-executive-day-rates "Fractional Executive Day Rates") in the UK typically range from £800–£1,500 depending on experience and sector. Monthly retainers for 2 days/week range from £6,400–£12,000. This represents a 50-70% saving versus a full-time CFO with salary, benefits, and equity.

Key responsibilities include:
Financial strategy and planning
Fundraising support (models, decks, DD)
Board reporting and KPI dashboards
Cash flow management and forecasting
M&A preparation and execution
Financial systems implementation
Team hiring and development

Fractional CFO vs Part-time FD: What is the Difference?
The key differences are seniority and scope. A fractional CFO operates at board level, focusing on strategy, fundraising, and investor relations.
