Enter six figures to get an indicative value range for your practice, with every adjustment shown. The calculation runs in your browser.
The table lists every figure the calculator used and every adjustment it made, and it updates as you change an input.
| Factor | Your figure | Effect on multiple |
|---|
Based on your inputs, these are the changes that would move the number most. Each row recalculates the whole valuation with that one factor at its strongest setting, and shows the difference in the mid-point.
| If you improved… | To | Mid-point moves by |

We'll email your figures to you with a written note on what would move the multiple for your firm. If you ask, we will also give you our own indicative range as a buyer, and we will sign an NDA if you want one.
UK accountancy practices below the mid-tier are usually bought and sold on a multiple of gross recurring fees. Profit is a poor guide, because the reported profit of an owner-managed firm depends on how the owner chooses to pay themselves (salary, dividends, pension, the car, the spouse on the payroll), so two identical practices can show completely different profit figures. Recurring fees measure what a buyer is acquiring: clients who pay predictably, every year, for work they are required to have done.
The arithmetic has two parts. First, establish the recurring fee base. Second, decide what multiple that fee base deserves. The calculator does the second part by starting from a multiple you set, then applying stated adjustments for the five things that determine how safely and completely that income transfers to a new owner.
Count only fees that repeat. Annual accounts and corporation tax, ongoing personal tax returns, bookkeeping, VAT and payroll retainers and company secretarial work are recurring. A one-off R&D claim, a single restructuring job, a probate matter or ad-hoc consultancy that will not repeat is not recurring, however profitable it was. If you overstate this figure, a buyer will remove anything that does not repeat and redo the sums, and the price will fall.
The box defaults to 1.00×, the same starting point as our main valuation page. That is Practice Group's own working assumption for a general UK practice with no obvious strengths or weaknesses. It is not a market statistic, and you can change it. If a broker or another buyer has quoted you a different number, or you know what a comparable local firm changed hands for, type that in instead. The adjustments are applied to whatever you enter.
Each factor moves the multiple by a stated amount. These weights are Practice Group's assumptions about how transferable fee income is, expressed in points of multiple. They are shown in full so you can disagree with any of them and adjust your starting multiple to compensate.
| Factor | Band | Adjustment |
|---|---|---|
| Owner hours a week on fee-earning work | 0–10 | +0.12 |
| 11–20 | +0.06 | |
| 21–30 | 0.00 | |
| 31–45 | −0.08 | |
| 46+ | −0.15 | |
| Fee-earning staff (FTE, excluding you) | None | −0.10 |
| 1–2 | −0.03 | |
| 3–5 | +0.03 | |
| 6 or more | +0.06 | |
| Advisory share of fees | 0–5% | −0.05 |
| 6–15% | 0.00 | |
| 16–30% | +0.05 | |
| Over 30% | +0.08 | |
| Top-10 client concentration | 20% or less | +0.08 |
| 21–35% | +0.03 | |
| 36–50% | −0.04 | |
| 51–65% | −0.10 | |
| Over 65% | −0.18 | |
| Average client tenure | Under 3 years | −0.08 |
| 3–5 years | 0.00 | |
| 6–9 years | +0.05 | |
| 10 years or more | +0.09 | |
| Owner-dependency score (used instead of hours and staff if you enter one) | 80–100 | +0.15 |
| 60–79 | +0.07 | |
| 40–59 | 0.00 | |
| 20–39 | −0.10 | |
| 0–19 | −0.20 |
The adjusted multiple is then held inside a floor of 0.40× and a ceiling of 1.60×, because beyond those points the formula no longer reflects real sales. The range you see is the adjusted multiple plus or minus 0.10×, which reflects how much the price can move between a good deal structure and a poor one on otherwise identical figures.
A firm with £300,000 of recurring fees, 10% advisory, 40% top-10 concentration, an owner doing 25 hours a week of production work, 3 fee-earning staff and 6-year average tenure, starting from 1.00×:
| Starting multiple | 1.00× |
| Owner hours (25 → 21–30 band) | 0.00 |
| Staff (3 → 3–5 band) | +0.03 |
| Advisory (10% → 6–15% band) | 0.00 |
| Concentration (40% → 36–50% band) | −0.04 |
| Tenure (6 years → 6–9 band) | +0.05 |
| Adjusted multiple | 1.04× |
| Range applied (±0.10) | 0.94× – 1.14× |
| Indicative value | £282,000 – £342,000 |
If the same firm's owner does 50 hours a week of production work and there are no staff, the multiple falls to 1.00 − 0.15 − 0.10 + 0.00 − 0.04 + 0.05 = 0.76×, and the range becomes £198,000 to £258,000. The fees are identical, and the mid-point is roughly £84,000 lower because the firm depends on one person.
A calculator with six inputs gives a starting point and leaves several things out. It does not know your lock-up and debtors — a firm carrying nine months of unbilled work in progress is worth less than the fee figure suggests. It does not know whether your fees are adequately priced; under-charged clients mean the buyer inherits a re-pricing job and the client losses that come with it. It does not know your retention history, only your average tenure, and the two are not the same thing. It knows nothing about your systems and software, your lease, your professional indemnity history, or whether your team will stay.
It also cannot see deal structure, which often matters more than the headline price. Two offers at the same number are worth very different amounts depending on how much is cash on completion, how much is deferred over one to three years, and how much is contingent on clients staying. A lower price paid mostly in cash can be worth more than a higher one that is two-thirds at risk.
Small and mid-sized UK practices are usually valued on a multiple of gross recurring fees. Profit is a poor guide, because an owner-managed firm's reported profit depends heavily on how the owner pays themselves. A starting multiple is chosen, then adjusted up or down for the quality and transferability of the fee income: owner dependency, fee mix, client concentration, client tenure and the depth of the team. This calculator follows that method and shows every adjustment it makes.
The calculator defaults to 1.00× recurring fees, the same starting point as our main valuation page. That default is Practice Group's own working assumption for a general UK practice and is not a published market statistic, so the box can be edited. If you have been quoted a multiple, or you know what comparable firms in your area have changed hands for, put that number in instead and the adjustments will be applied to it.
No. It is an indicative range produced from six inputs. It is not a formal valuation, not advice and not an offer. A full valuation looks at your fee list client by client, your recurring split, lock-up and debtors, staffing, retention history and the deal structure on the table. A six-field calculator cannot see any of those.
A buyer is purchasing the fee income the firm will earn after the sale. If the relationships, the pricing judgement and the technical sign-off all sit with the owner, a large part of what is being bought can leave with the owner on completion day. Buyers call this retention risk and reduce the price to allow for it. It is also the factor most within an owner's control in the 12 to 24 months before a sale.
Yes. Concentration measures what happens if one large client leaves, is sold or retires, however happy that client is today. If your ten largest clients are two-thirds of your fees, the loss of one is a material event for the buyer. A broad base of smaller recurring clients is worth more per pound of fees for that reason.
