A full-time Finance Director costs more than the salary. See the real cost difference between a Fractional Finance Director and an in-house hire, and which one fits your stage of growth.
A full-time Finance Director in the UK costs somewhere between £80,000 and £130,000 a year, depending on sector and location. Most business owners stop their cost calculation there. That's the mistake. The salary is the smallest part of the bill. Once you add employer National Insurance, pension contributions, bonus structure, benefits, recruitment fees, onboarding time, and the cost of a bad hire if it doesn't work out, a full-time FD typically costs your business £110,000 to £170,000 in year one alone. And that's before you've factored in what happens when they're on holiday, off sick, or job-hunting six months after you hired them. A Fractional Finance Director changes that equation entirely. You get the same calibre of strategic financial leadership, the same depth of experience, without carrying a six-figure fixed cost for a role that, in most growing businesses, doesn't need to be full-time yet. What a full-time FD actually costs you Break down the real cost of an in-house FD and the numbers add up fast. Base salary sits at £80,000 to £130,000 for an experienced FD outside London, more if you're competing in a tighter talent market. Add employer National Insurance at roughly 13.8% above the threshold, and pension auto-enrolment contributions on top. Most FD packages include a bonus structure, often 10-20% of salary, tied to performance. Then there's the cost of getting them in the building: recruitment agency fees typically run 20-25% of first-year salary if you go through a search firm, plus your own time spent interviewing, negotiating, and managing the process. Once they start, you're paying for a desk, equipment, software licences, and the months it takes them to properly understand your business before they're delivering full value. If the hire doesn't work out, and FD-level mismatches aren't rare, you're looking at severance costs and starting the whole process again. None of this accounts for what you're actually getting in return. A full-time FD is one person, with one set of experience, available for the hours they're contracted. If your business doesn't generate enough complexity to keep a Finance Director busy five days a week, you're paying full-time rates for part-time value. What a Fractional Finance Director actually costs you A Fractional Finance Director gives you Finance Director-level strategic input, scaled to what your business genuinely needs. Instead of one fixed salary regardless of workload, you pay for the level of support that matches where you are right now, whether that's a few days a month or more sustained involvement during a growth phase, a funding round, or a period of operational change. There's no recruitment fee, no onboarding period where you're paying full salary for partial productivity, no employer National Insurance, no pension contribution, no severance risk. You're not managing a direct report. You're working with an experienced finance professional who's already built the systems, seen the patterns, and made the mistakes elsewhere, so you don't have to fund that learning curve yourself. Because the cost scales with engagement level rather than sitting fixed at a full-time salary, most businesses save 40-60% compared to an equivalent in-house hire, while getting access to a broader range of expertise than any single full-time hire could offer alone. Why business owners default to full-time anyway The instinct to hire full-time is understandable. There's a cultural assumption that "proper" finance leadership means someone in the building every day. For some businesses, particularly larger or more complex operations, that's genuinely true. But for most growing construction, hospitality, and creative businesses, the need isn't constant Finance Director-level attention. It's reliable financial oversight day to day, with strategic, Finance Director-level thinking applied when decisions actually require it. Quarterly reviews. Cashflow forecasting before a big investment. A sounding board when you're weighing up a major contract or a funding decision. That's not a full-time job. It's expertise applied at the right moments. Paying full-time rates for that pattern of need means funding a lot of capacity you're not using. When full-time genuinely makes sense A Fractional Finance Director isn't the right fit for every business, and it's worth being direct about when it isn't. If your finance function has grown complex enough to need daily, in-person decision-making at FD level, if you're running a large team that needs constant in-house leadership, or if your business has reached a scale where the volume of strategic financial work genuinely fills a five-day week, a full-time hire earns its cost. The Fractional model works because it matches resource to need. Once that need becomes genuinely full-time, the maths shifts. The businesses we work with are almost always somewhere before that point: growing, profitable, complex enough to need more than a bookkeeper, not yet at the scale where a full-time FD's capacity gets fully used. How to work out which one you need Ask yourself three questions. How often does your business face decisions that genuinely need Finance Director-level strategic input, rather than day-to-day bookkeeping or compliance? Could your current financial oversight be handled by a structured, scaled support model rather than one person at a desk every day? And what would a six-figure fixed cost do to your cashflow if you're still in growth phase? If the honest answer is that you need expert oversight, strategic input at key decision points, and the confidence that comes from a clear financial picture, without the fixed cost of a full-time salary, a Fractional Finance Director gives you that. You scale the support up as your business grows, rather than overcommitting now and hoping the workload catches up to justify it. Talk to us before you commit to either You don't need to work this out alone. If you're weighing up a full-time hire against fractional support, talk it through with our team first. We'll look at where your business actually is, what level of financial oversight it genuinely needs right now, and what that should cost you, then give you a straight answer, even if that answer is that a full-time hire is the right call.
