Method
How the Estimate Is Built
Step 1
Start from adjusted profit
Profit before tax, interest and depreciation, with the owner's salary and personal costs added back. Buyers call it SDE for an owner-run business and EBITDA once a manager is paid to run it.
Step 2
Apply the published range
Owner-run businesses typically sell at 1.5x–3x SDE. UK SME deals under management cluster around the published medians of 4.5x EBITDA (UK200Group, 2025) and 3.9x for the smallest deals (MarktoMarket, 2025).
Step 3
Place it within the range
How much the business depends on you and how much revenue repeats decide whether a buyer pays the lower or the upper end. The calculator moves the estimate within the range; it never adds a premium on top.
Step 4
Add assets, deduct tax and fees
Freehold property and stock are added at value. Capital Gains Tax uses 2026/27 rates: 18% with Business Asset Disposal Relief on the first £1m, 24% above. Broker fees are shown at the typical 8%–12% plus VAT.
Benchmarks
UK Business Sale Multiples in 2026
Transaction indices only cover larger SME deals. For owner-run businesses the sector ranges come from broker and advisory guidance, so treat them as orientation rather than a valuation.

UK broker and advisory guidance
| Sector | Basis | Indicative range | What moves it |
|---|---|---|---|
| Cafés, restaurants & takeaways | SDE | 1.5x – 3x | Owner labour is most of the profit; lease length and landlord consent decide the rest |
| Hair, beauty & wellness | SDE | 1x – 2.5x | Revenue follows the stylist, not the premises |
| Garages & MOT centres | SDE | 2x – 3.5x | DVSA approval is a genuine barrier to entry |
| Cleaning & facilities services | adjusted profit | 1.5x – 5x | Contract length, notice periods and customer concentration decide where in the range |
| E-commerce & online | SDE | 2.5x – 5x | Own traffic and repeat customers pull it up; dependence on one marketplace pulls it down |
| Care homes | EBITDA | 4x – 8x | Property-backed, but registration, occupancy and fee mix add risk |
| Any other owner-run business | SDE | 1.5x – 3x | Broad UK market range for owner-operated businesses |
| Any other business under management | EBITDA | 3.3x – 6x | Span of published UK SME median multiples, 2021–2025 |
Sector rows are indicative ranges for owner-managed businesses, not transaction data. The two "any other" rows are the published ranges the calculator falls back on when a sector has no reliable benchmark.

Adjusted profit
Which Add-Backs Survive Due Diligence
Statutory net profit rarely shows what a business earns for its owner. Buyers value adjusted profit, but only evidenced add-backs get past their accountant.
Usually accepted
Documented, non-recurring or owner-specific costs.
- Owner's salary, pension and NICs above a market-rate replacement, or all of it for SDE
- Depreciation and amortisation
- Interest on loans and finance that will be repaid at completion
- One-off legal, restructuring or relocation costs with invoices to match
- Personal vehicle, private medical and family payroll that stops after the sale
Usually rejected
Costs a buyer will still carry, or income nobody can verify.
- Cash takings that do not reconcile with VAT returns and bank statements
- Recurring marketing or software spend labelled as one-off
- Below-market rent where you own the freehold and have not charged a market rent
- Deferred repairs and compliance work needed to keep trading
- Overtime and agency staff needed to deliver current turnover
What moves the price
Why Two Similar Businesses Sell at Different Multiples
The range for a sector is wide. These are the factors that decide whether a buyer pays the lower or the upper end of it.
Owner dependency
If quotes, scheduling and key clients run through you, the business is bought as a job. A team or manager that runs the day to day is the biggest single move up the range.
Repeat and contracted revenue
Maintenance agreements, retainers and subscriptions lower a buyer's risk and make bank funding easier. One-off sales do the opposite.
Customer concentration
One client making up a large share of turnover is a risk buyers price in, often by moving part of the price into deferred payment or an earn-out.
Lease and premises
For hospitality, retail, care and automotive, an assignable lease with years left, or a freehold, protects the goodwill you are selling.
Clean, reconcilable accounts
Management accounts that tie to Companies House filings, VAT returns and bank statements keep the headline offer intact through due diligence.
Licences that transfer
DVSA MOT authorisation, CQC or Ofsted registration and premises licences are barriers to entry, but they only add value if the buyer can take them over.
