How Much Does a Part-Time FD Cost?

A part-time FD service typically costs between £1,000 and £5,000 per month for a UK SME, depending on the seniority of the Finance Director, the number of days engaged, and the complexity of your business. Understanding what drives that figure — and what represents genuine value — is essential before you commit to an engagement.

This guide breaks down part-time FD pricing clearly, so you can assess whether the investment is right for your business and what you should expect in return.

What Is the Typical Day Rate for a Fractional Finance Director?

A fractional Finance Director's day rate in the UK typically sits between £600 and £1,500 per day, with the median for experienced FDs working with growing SMEs around £800 to £1,000 per day. These figures reflect qualified finance professionals — typically ACA, ACCA, or CIMA-qualified — with genuine board-level experience rather than senior accountants operating outside their depth.

Day rates vary based on several factors:

• Seniority and track record: An FD who has led multiple exits, raised institutional funding, or managed complex group structures commands a higher rate than one whose experience is limited to basic financial reporting.
• Industry specialism: FDs with deep knowledge of your sector — whether SaaS, manufacturing, hospitality, or professional services — typically charge a premium that is usually justified by faster time-to-value.
• Geographic location: FDs based in London and the South East typically charge 10–20% more than those working remotely from other regions, though remote engagements have substantially reduced this premium since 2020.
• Engagement structure: A retained FD working a fixed number of days per month will generally offer a lower effective day rate than one engaged on an ad hoc project basis.

Monthly Retainer Costs: What Should You Expect to Pay?

Most part-time FD engagements are structured as monthly retainers covering a set number of days. The table below gives a realistic picture of what businesses at different growth stages typically pay:

Business Stage	Days Per Month	Typical Monthly Cost
Early-stage / startup (£500k–£2m turnover)	1–2 days	£800 – £2,000
Growing SME (£2m–£10m turnover)	2–4 days	£1,500 – £4,000
Scale-up / pre-exit (£10m+ turnover)	4–8 days	£3,500 – £8,000

These figures represent the FD's professional fees only. Platform fees, expenses, and any specialist third-party costs are separate considerations covered in our article on hidden costs and additional fees to watch for.

How Do These Costs Compare to Other Finance Options?

Versus a full-time Finance Director

A full-time Finance Director employed in the UK costs between £90,000 and £160,000 in base salary alone. Add employer's National Insurance contributions, pension auto-enrolment, holiday pay, sick pay, recruitment fees (typically 15–25% of first-year salary), and the real employment cost rises to £120,000–£200,000 per year. A part-time FD engagement at £3,000 per month costs £36,000 annually — a saving of £80,000 or more for equivalent strategic financial leadership, without the fixed overhead commitment. For a detailed breakdown, see our comparison of part-time FD costs versus full-time employment.

Versus a senior accountant or finance manager

Some businesses attempt to bridge the gap with a Finance Manager at £40,000–£60,000 per year. A Finance Manager produces management accounts and handles day-to-day finance operations competently, but rarely provides the strategic oversight, commercial challenge, and board-level credibility that a fractional FD delivers. The two roles serve different purposes and are not directly interchangeable.

What Factors Drive the Cost Up or Down?

Several variables determine where on the pricing spectrum your engagement falls:

Complexity of your financial situation

A business with straightforward domestic revenues, a clean balance sheet, and a small finance team requires less FD time than one managing multi-currency transactions, group consolidation, HMRC compliance disputes, or complex debt facilities. The more nuanced the financial environment, the more senior experience you require and the higher the commensurate cost.

Urgency and turnaround requirements

Businesses undergoing rapid transformation — a fundraise, an acquisition, a restructuring, or preparation for sale — typically need more intensive FD involvement in a compressed timeframe. Project-based or surge engagements carry a higher per-day cost than steady-state retained arrangements.

The platform or sourcing route

Engaging a fractional FD through a specialist platform like FractionalFD provides vetting, matching, and contract infrastructure that reduces your risk and sourcing cost. Sourcing directly through your network may appear cheaper initially but carries hidden costs: time spent evaluating candidates, no performance guarantee, and no replacement assurance if the engagement does not work out.

Is a Part-Time FD Cost-Effective for Your Business?

The right question is not "how much does a part-time FD cost?" but "what return does that cost generate?" A well-deployed fractional FD typically delivers value through improved cash flow forecasting, tighter working capital management, successful fundraising at better terms, identification of cost savings, and stronger financial governance that reduces risk.

"A good FD pays for themselves many times over. The question is whether you have enough financial complexity to justify the engagement — and most businesses beyond £1m in turnover do."

How to Budget for a Part-Time FD

When building a budget for a fractional FD engagement, businesses should account for:

• Monthly retainer fee — the core engagement cost, paid in advance or monthly in arrears depending on the contract terms
• Expenses — reasonable travel and subsistence if on-site attendance is required; typically capped and pre-agreed
• VAT — fractional FD services are subject to VAT at 20%, recoverable if your business is VAT-registered
• Ad hoc project work — some engagements scope in a fixed number of project days per quarter for intensive work such as budget preparation, board pack production, or fundraise support

Most engagements operate on a minimum three-month initial term, after which they roll monthly. For more detail on contract structures and minimum commitments, read our article on minimum contract lengths for fractional FD engagements.
