Fractional data analyst vs hiring full-time: a UK cost guide

The decision most growing businesses get wrong

There is a point in most growing businesses where the spreadsheets stop coping. Reports take too long, nobody quite trusts the numbers, and someone says it out loud: we need a data person. The usual next step is a job advert for a full-time data analyst.

Sometimes that is exactly right. Often it is not. A fractional data analyst, meaning an experienced analyst who works for you a set number of days each month rather than five days a week, can give a small business the same skills for a fraction of the cost, and without the risk of a hire that does not work out.

This guide compares the two options using real 2026 UK figures for salaries, day rates, National Insurance and pensions, shows the point at which hiring becomes cheaper, and gives you a simple way to decide. If you want the detail on day rates themselves, read my companion piece, How much does a freelance data analyst cost in the UK?, first.

What a fractional data analyst actually is

"Fractional" is a newer word for an old idea. Instead of one person doing the job full-time, you buy a fixed slice of an experienced person's time, usually somewhere between one and eight days a month, on a rolling arrangement. The analyst gets to know your business, your systems and your people, but you only pay for the days you use.

It differs from a one-off freelance project in one important way: continuity. A project builds something and ends. A fractional arrangement keeps going, so the same person maintains your reports, answers the questions that come up each month and improves things as the business changes.

The real cost of a full-time data analyst

Start with salary. According to IT Jobs Watch's permanent salary data, the median advertised salary for a data analyst in the UK was £57,500 in the six months to 9 November 2026, and £55,000 outside London. The Yorkshire median shows as £65,000, but that comes from only 104 adverts, so treat it as a rough signal rather than a reliable local figure.

Salary is only the start. Using £55,000 as the example, these are the costs an employer pays every year:

• Employer National Insurance at 15% on earnings above the £5,000 secondary threshold, according to HMRC's rates and thresholds for 2026 to 2027. On a £55,000 salary that is £7,500.
• A workplace pension. The legal minimum is 3% from the employer on qualifying earnings between £6,240 and £50,270, as set out on GOV.UK's workplace pensions page. That is about £1,321 a year, and many employers pay more.
• Equipment, software licences and training. This varies a lot, so I have used an assumed £2,000 a year as a placeholder. A laptop, a Power BI or similar licence and one course would get you there quickly.

That gives a recurring cost of about £65,821 a year before you have paid for recruitment, office space or management time. If your business can claim the Employment Allowance, which is £10,500 for 2026 to 2027 on the same HMRC page, and you have not already used it on existing staff, it could cancel out the National Insurance in this example. Check your own position with your accountant.

The days you are actually paying for

A full-time employee is entitled to 5.6 weeks of paid holiday a year, which is 28 days for someone working five days a week (GOV.UK holiday entitlement). That leaves roughly 232 working days out of 260. Divide £65,821 by 232 and each available day costs about £284, before sickness, training days and the first few months it takes anyone to learn a new business.

On a per-day basis, then, a permanent analyst is cheaper than a freelancer. The catch is that you pay for all 232 days whether or not you have 232 days of useful work.

The costs that do not show up on the payslip

• Recruitment. If you use an agency, the fee is usually a percentage of first-year salary. Even if you recruit yourself, interviewing takes weeks of senior time.
• Ramp-up. A new analyst needs time to learn your systems and data before their output can be trusted. Expect the first two or three months to be slower.
• Management. Analysts work best when someone senior sets priorities and reviews the work. If nobody in the business can do that, a junior hire can end up building reports nobody asked for.
• A single point of failure. When they are on holiday, off sick or leave, the reports stop.

The real cost of a fractional data analyst

IT Jobs Watch puts the median UK contract day rate for data analysts at £474 for the same six months, and £427 outside London (contract rate data). Fractional arrangements are often priced as a fixed monthly fee, but a day rate is the easiest way to compare. Using £474 a day:

• Two days a month, enough to maintain a monthly reporting pack and answer questions: £11,376 a year.
• Four days a month, enough for regular reporting plus one improvement project each quarter: £22,752 a year.
• Eight days a month, close to a part-time analyst embedded in the business: £45,504 a year.

There is no employer National Insurance, pension, holiday pay, equipment or recruitment fee on top. You pay for the days you use and can usually change the number of days with a month's notice.

Side by side: the worked example

Here is the comparison in one place. The full-time figures use the £55,000 example above, including the assumed £2,000 for equipment and software, and exclude recruitment. The fractional figures use the £474 median day rate. These are illustrative numbers, not a quote.

Option                          Days of work   Annual cost
                                   per year           (£)
-------------------------------------------------------------
Full-time hire, £55,000 salary    about 232        65,821
Fractional, 2 days a month               24        11,376
Fractional, 4 days a month               48        22,752
Fractional, 8 days a month               96        45,504
-------------------------------------------------------------
Break-even: £65,821 / £474 = about 139 days a year,
or roughly 11 to 12 days a month

In this example, a fractional analyst is cheaper until you need more than about 11 days a month. Above that, a full-time hire wins on cost, as long as you can recruit the right person, give them enough direction and keep them busy. If you add a recruitment fee, the break-even point moves further in favour of fractional support.

When a full-time hire is the right call

I would rather tell you when you do not need someone like me. Hiring full-time makes sense when:

1. You genuinely have more than two or three days of analytics work every week, and you can see it continuing for years rather than months.
2. Data is central to how the business makes money, for example a pricing-led retailer or a business selling data-driven services.
3. You have someone who can manage an analyst: set priorities, review the work and turn the findings into decisions.
4. You want to build a team, and the first analyst is the foundation for the second and third.

When fractional makes more sense

For most small and medium-sized businesses, the honest picture is a burst of work to get the foundations right, followed by a steady trickle of reporting, questions and improvements. Fractional support fits that shape well when:

• You need experience more than hours. A fractional analyst has usually seen your problem in other businesses and knows the shortcuts.
• Your data is still messy. Most of the early work is joining up spreadsheets and systems, which the 30-day data starter kit shows you can partly do yourself first.
• You are not sure what you need yet. A few months of fractional work will tell you whether you have a full-time role, which makes any later hire far less risky.
• You want to keep fixed costs down. It is the same logic I set out in The Smarter Way to Cut Costs: spend in proportion to the problem rather than adding fixed overhead by default.

The hybrid route

There is a middle path that works well for growing businesses. Use a fractional analyst to set up the reporting, the definitions and a working forecast, such as the method in my guide to sales forecasting for small businesses. Then, if the work grows, hire a more junior analyst to run it day to day, with the fractional analyst dropping to a day or two a month for reviews and harder problems. You get the experience when it matters most and a lower salary bill for the routine work.

How to get value from a fractional analyst

Fractional support only works if the days are well used. Three habits make the difference:

1. Agree the few numbers that matter. Before the first day, pick the three to five measures you most need to see every week. The 5 Metrics That Actually Matter is a good starting list.
2. Insist on documentation and handover. Everything built for you should be written down and runnable by your team, so you are never locked in to one person.
3. Use standard tools where you can. As I argued in Buy the standard parts, build the part that is yours, most of your reporting should run on tools you already pay for, with custom work saved for what is specific to you.

If you want the wider context on where analytics pays off for a business your size, my guide to data analytics for SMEs covers it.

Frequently asked questions

What is the difference between a fractional and a freelance data analyst?

The skills are the same. The difference is the arrangement. A freelance project has a defined deliverable and an end date. A fractional arrangement is ongoing, with a set number of days each month, so the same analyst builds up knowledge of your business over time.

How many days a month does a small business need?

Most small businesses I work with need between one and four days a month once the initial setup is done. The setup itself usually takes a concentrated few weeks.

Does IR35 apply to a fractional data analyst?

It can, so it is worth checking. If your business counts as small under the Companies Act, the contractor is responsible for deciding their own employment status, not you. Medium and large organisations have to make the decision themselves. GOV.UK explains the off-payroll working rules.

Can a fractional analyst help us hire a permanent one later?

Yes, and it is one of the best uses of the arrangement. Someone who already knows your data can write a realistic job description, help interview candidates and hand the work over properly.

Is a fractional data analyst cheaper than a full-time hire?

In the worked example above, yes, until you need more than about 11 or 12 days of work a month. Above that, a full-time hire is cheaper on paper, provided you can recruit and manage the right person.

Not sure which route fits your business?
