Pricing Your Fractional Finance Work: A Practical Guide

Pricing is the part of fractional practice that finance professionals handle worst, which is an irony worth noting. People who spend their working lives on margin analysis routinely set their own rate by taking their former salary, dividing by 220 and adding a bit — which produces a number that is both arbitrary and usually too low. This guide covers what the market actually pays, why the day-rate calculation misleads, how retainers change the economics, and how to raise rates without losing the clients you have.

Why the salary-divided-by-days calculation is wrong

The instinct is to price against what you earned. A £95,000 Financial Controller divides by 220 working days, gets £432, rounds to £450, and feels they have priced fairly. Three things are missing.

Employment cost, not salary. That £95,000 cost the employer closer to £114,000 with National Insurance, pension and benefits — current rates are on gov.uk. The honest comparator is £518 a day, not £432.

You will not bill every working day. Business development, admin, holiday, illness and the gaps between engagements are real. A realistic fractional practitioner bills 140–180 days a year, not 220 — and the rate has to carry the unbilled time.

And you are not selling time, you are selling accountability. The client is buying someone answerable for the numbers being right, which is why a fractional FC at £4,000 a month is compared against a £114,000 permanent hire rather than against an hourly rate.

Work it back properly: to earn the equivalent of a £95,000 package at 160 billable days, with practice costs, you need roughly £750 a day — which is above market. The realistic conclusion is that fractional pays better than employment through volume of clients and rate discipline, not through the day rate alone.

Qualification — ICAEW, ACCA or CIMA — is assumed at these levels rather than priced. Three factors move you within the band: scarcity of the specific experience — regulated, consolidation, systems implementation and sector depth all price up; the state of what you are inheriting, since a rescue prices above maintenance; and whether the client has an alternative. A business that has already tried and failed to recruit permanently is a different conversation from one comparing three fractional providers.

Day rate or retainer?

For anything ongoing, retainer, and the reasons run both ways.

For the client: a predictable monthly cost that sits in the budget, no invoice surprises, and no conversation about hours that discourages them from asking a question.

For you: predictable income, no time recording, and an engagement defined by outcomes rather than attendance — which is where the value actually is.

A retainer is normally expressed as days per month at a modest discount to the day rate — five per cent is typical, ten is generous. The discount buys commitment and predictability, and it is worth it.

Day rates remain right for genuinely variable work, for a first engagement where neither side knows the shape yet, and for bounded projects — a systems implementation, a first audit, a consolidation build — which should be priced separately from the ongoing retainer rather than absorbed into it.

The retainer arithmetic

Days/week	Days/month	At £500/day	Typical retainer	Client comparison
1	~4.3	£2,150	£2,000–£2,400	vs £114k permanent
1.5	~6.5	£3,250	£3,000–£3,600	—
2	~8.7	£4,350	£4,000–£4,800	—
3	~13	£6,500	£6,000–£7,200	—

The right-hand column is the one to keep in mind during a pricing conversation. A client paying £4,200 a month is spending £50,400 a year for senior finance accountability — against £114,000 fully loaded for the permanent equivalent, with recruitment cost, notice period and employment risk attached. Framed that way the conversation is straightforward, and it is the framing our guide to outsourced FC services uses with clients.

What to price separately

Four things that should never be absorbed into an ongoing retainer, because they destroy its economics.

Bounded projects — a systems implementation, a first consolidation, an audit remediation. Scope them, price them at a project rate, and deliver them alongside rather than inside the retainer.

Transaction support. Due diligence and fundraising are intense, unpredictable and higher-value; they warrant a separate rate.

Anything below your level. If the client needs bookkeeping, they need a bookkeeper — and helping them find one is more useful than doing it yourself at FC rates.

And genuine scope expansion. The commonest way fractional engagements become unprofitable is quiet growth: a bit more each month until two days is doing three days’ work. Raise it early, factually, and re-scope. Clients almost always accept it; the difficulty is entirely in the raising.

Raising rates

Fractional practitioners are notoriously bad at this, and the cost compounds. Four practical points.

Review annually, on a date. Deciding in advance that you review every January removes the question of whether now is the right moment.

Raise for new clients first. If raising existing rates feels difficult, price new engagements higher and let the average move. Within eighteen months the portfolio has repriced itself.

Give notice and a reason. Two or three months’ warning, and a factual basis — market rates, the scope as it has developed, the length of the relationship. Clients budget annually and dislike surprises far more than they dislike increases.

And accept that you may lose one. A client who will not accept a reasonable increase after two years is usually the one taking most of your time for least of your money. Losing them creates capacity for a better-priced engagement, which is generally a good trade.

The portfolio view

One final piece of arithmetic that people miss. Your effective rate is not what you charge; it is what you earn divided by all the days you work, billed or not. A practitioner charging £600 a day but billing 130 days earns less than one charging £500 and billing 175.

That means utilisation is at least as important as rate, and the levers on it are different: retainers rather than ad-hoc work, a referral network that keeps the pipeline warm, and enough clients that losing one is inconvenient rather than serious. Three or four retained clients at one to two days each is the shape most successful fractional practices settle into.
