Dental practice valuation calculator.
Goodwill estimate from EBITDA, revenue mix and freehold. Built on UK dental market data and intentionally conservative — use it to frame the conversation, not settle the sale.
Last 12 months, or average of last 3 years if revenue is volatile
Post-associate-payouts. A sensible UK dental practice range is 15–35%. If unsure, 25% is a reasonable start.
0% = fully private, 100% = fully NHS. This drives the multiple.
Buyer due diligence scrutinises this — it moves the multiple materially
Enter 0 if you rent. Freehold sits separately from goodwill — added to the total.
Estimates only. A buyer's accountant will scrutinise EBITDA normalisation, associate retention evidence, and UDA recovery risk — all of which shift the real number. Use this to frame the conversation, not settle it.
What this doesn't do.
- Does not account for patient-list age, treatment-mix trends, or contract renewal risk — all of which a buyer's accountant will scrutinise.
- Does not model lease terms, break clauses, or restrictive covenants that affect deal structure.
- Does not normalise owner-operator remuneration — a specialist will add back sub-market principal salaries to increase defensible EBITDA.
- Does not replace a formal written valuation report. For a sale, bank finance, partnership restructure, or probate, you need the written document.
Questions.
How accurate is this calculator?+
It gives a conservative ballpark consistent with UK dental market data. A real valuation depends on things this tool can't see: associate retention contracts, lease terms and break clauses, patient-list age, treatment-mix trends, principal remuneration normalisation, and UDA contract risk. Expect the real number to land within 20% of this estimate in most cases, further out if your practice has unusual features.
Why is the NHS share so important?+
NHS income carries contract-specific risks (UDA recovery, contract renewal, performer-number scrutiny) that private income does not. Buyers discount NHS revenue accordingly. A practice at 80% NHS typically trades at 3.5–5.0× EBITDA; a practice at 80% private typically trades at 5.5–7.0× EBITDA. The multiple scales smoothly between those extremes.
What is EBITDA in this context?+
Earnings before interest, tax, depreciation and amortisation — but crucially, after associate pay-outs. For most UK dental practices, EBITDA lands at 15–35% of gross fee income. If you have genuine owner-operator remuneration treated as salary, a specialist will normalise it back into EBITDA for valuation purposes, which often increases the defensible number.
Does this cover partnership buy-ins or just whole-practice sales?+
The goodwill logic is the same for a whole-practice sale and for a proportionate partnership buy-in — the valuation math scales with the stake. What differs is the premium or discount applied for minority stakes, ongoing obligations, and restrictive covenants. For a partnership buy-in, use this tool to frame the conversation and commission a specialist to negotiate the detail.
Why doesn't this tool include location or local market?+
Because the local market effect is usually smaller than dentists think. Within Greater London, goodwill multipliers vary less by postcode than by practice-specific factors (associate stability, treatment mix, contract terms). Our dental-specialist accountants benchmark your practice against truly comparable sales — not an average — when they produce the real valuation.
