Fractional CFO Cost Per Month
How Much Does a Fractional CFO Cost Per Month?
For growing startups, especially those who've just raised funding, getting professional CFO-level financial expertise is crucial. However, hiring a full-time CFO is a significant commitment, both financially and operationally. This leads many UK startups and SMEs to consider a fractional CFO instead. But how much does a fractional CFO really cost per month—and is it worth it?
The Real Cost of Hiring a Full-Time CFO in the UK
First, let’s consider the baseline. A full-time CFO salary can be steep, especially in London. Recent industry benchmarks show average annual salaries for senior finance roles in London and across the UK:
- Chief Financial Officer: £162,000 (London) / £120,000 (UK average)
- Finance Director: £140,000 (London) / £100,000 (UK average)
- Head of FP&A: £130,000 (London) / £85,000 (UK average)

Beyond salaries, full-time hires come with additional hidden costs such as:
- Recruitment fees and onboarding expenses
- Benefits, pension contributions, and bonuses
- Training and induction periods, typically lasting 2-3 months
These additional expenses can easily add another 20-30% to the headline salary cost.
How Fractional CFO Pricing Typically Works
Fractional CFO services generally use monthly retainer models tailored to your specific needs—often significantly lower than a full-time executive’s salary. Typical fractional CFO monthly fees range from around £2,500 to £8,000, depending on complexity and involvement frequency.
At Valuefinex, our clients typically see savings between 50%-70% compared to hiring an in-house senior finance professional. Accumulated savings clearly demonstrate the value of fractional CFO engagements:
- Month 3: Over £8,000 cumulative savings
- Month 6: More than £16,000 cumulative savings
- Month 12: Total accumulated savings exceed £32,000
Unlike full-time hires, a fractional CFO hits the ground running immediately—no lengthy induction or ramp-up time required.
Why Fractional CFO Services Offer Better Value

There’s more to fractional CFOs than cost savings alone. Here’s what makes fractional services particularly attractive for growing startups:
- Immediate Expertise: Fractional CFOs are operational from Day 1—saving valuable time during critical growth phases.
- Flexibility: Easily scale up or down based on your needs, ensuring you never overpay.
- No Long-term Commitment: Pause or stop services quickly if your business circumstances change.
- Senior-Level Insight: Access strategic insights without full-time executive overhead.
When Should You Consider a Fractional CFO?
Startups typically benefit most from fractional CFO services in these situations:
- After raising seed or Series A funding
- Preparing for subsequent funding rounds (Series B and beyond)
- Scaling operations internationally or increasing business complexity
- When financial management surpasses founders' comfort levels
Fractional CFOs offer critical senior financial guidance exactly when and where you need it.
Bottom Line: Fractional CFOs Offer Serious Savings and Real Value
