Fractional CFO: role, services, cost and benefits (UK guide 2026)
A fractional CFO (also called an outsourced or part-time CFO) gives a growing company access to senior financial leadership without the cost of a full-time hire. This guide covers what a fractional CFO does, who needs one, how much it costs and the real benefits for SMEs.
What is a fractional CFO?
A fractional CFO is an experienced finance director who works for your business on a part-time, flexible basis — typically one to three days a week — instead of a full-time salaried role often oversized for an SME. They steer your finance function (budgeting, cash flow, reporting, board reporting, banking, fundraising) while you only pay for the days you actually need.
What does a fractional CFO do?
- Reporting & KPIs: management accounts, dashboards, board and investor reporting.
- Cash flow & funding: forecasting, banking relationships, raising finance, working capital.
- Budgeting & control: budgets, variance analysis, margin and profitability analysis.
- Strategic operations: fundraising, M&A, due diligence, business planning.
Who needs a fractional CFO?
Fractional CFOs are ideal for SMEs and scale-ups (10 to 250 staff) that have outgrown a bookkeeper but cannot justify a full-time CFO. Typical triggers: rapid growth, a funding round, the departure of a finance lead, or the need to reassure banks and investors with reliable reporting.
How much does a fractional CFO cost?
Pricing is based on a day rate. In 2026, an experienced finance director typically charges £600 to £1,400 per day. At 4 to 8 days a month that is far below the ~£120,000+ all-in cost of a full-time CFO (salary plus on-costs), for a more senior profile and full flexibility.
Fractional CFO vs interim CFO
A fractional CFO is an ongoing, part-time arrangement. An interim CFO is a temporary, often full-time mission to cover a gap or lead a transformation. Choose fractional for a permanent light-touch need, interim for a temporary intensive one.

How many days a month does a fractional CFO work?
Usually 4 to 8 days a month for an SME, scaling up around year-end close or a fundraise.
Is a fractional CFO employed?
No, they are an independent consultant engaged on a contract basis, so you avoid employment costs and fixed overheads.
