Earnings-based valuation
An earnings approach links an appropriate earnings measure to evidence about value. The difficult work lies in normalising performance and selecting relevant comparables. Enterprise-value multiples and equity-value multiples must not be mixed: they relate to different measures and financing assumptions.
Discounted cash flow
DCF estimates present value from future cash flows and an appropriate discount rate. The forecast needs a coherent link between sales, margins, investment and working capital. Small changes in long-term assumptions can have a large effect, so sensitivity analysis matters more than the apparent precision of the final number.
Asset-based valuation
An asset approach considers assets and liabilities on a relevant valuation basis. Accounting book values may differ from realisable or market values. It may be useful for asset-holding entities or particular circumstances, but does not automatically capture a trading business’s earning capacity or internally generated intangible value.
A practical selection framework
Ask whether current earnings are representative, whether forecasts are credible and whether asset value is central to the business. Cross-check approaches where useful, but do not average unrelated results simply to produce a compromise. Explain why one method carries more weight.
What an online calculator can and cannot do
A calculator can show arithmetic and sensitivities. It cannot verify accounts, choose a defensible market multiple or interpret contractual share rights. Use our scenario tool to understand the mechanics, then discuss the evidence needed for a company-specific assessment.
Business valuation methods compared
Start with the purpose and valuation date, then ask which evidence is reliable. A profitable trading company and an asset-holding company may need different approaches.
| Valuation method | When it can help | Evidence to examine | Common mistake |
|---|---|---|---|
| Earnings multiples | An established trading business with representative earnings | Sustainable EBITDA or another consistent profit measure; relevant comparable evidence | Using an unsupported multiple or adding back the owner’s pay without replacement costs |
| Discounted cash flow | A business with supportable forecasts and changing cash flows | Cash conversion, investment, working capital, forecast scenarios and discount-rate assumptions | Treating an ambitious forecast as a certain outcome |
| Asset-based approach | An asset-holding business or a case where asset values are central | Relevant asset values, obligations and the costs of realisation where applicable | Assuming balance-sheet book values equal market values |
Worked example: from profit to equity value
Consider a hypothetical owner-managed business. Reported EBITDA is £220,000. A genuine one-off cost is £15,000. The accounts include £90,000 of owner remuneration, but replacing the owner’s work would cost £70,000.
| Step | Illustrative calculation |
|---|---|
| Normalised EBITDA | £220,000 + £15,000 + £90,000 − £70,000 = £255,000 |
| Enterprise value at an assumed 4× EBITDA | £255,000 × 4 = £1,020,000 |
| Equity value before other adjustments | £1,020,000 + £100,000 cash − £250,000 debt = £870,000 |
| Sensitivity at an assumed 3× and 5× | Equity value would be £615,000 and £1,125,000 respectively |
The multiples are arbitrary teaching assumptions, not market benchmarks or recommended prices. This example excludes working capital adjustments, other debt-like items, share rights, fees and tax. Selecting a defensible multiple requires relevant evidence.

Can I value a business using turnover alone?
Turnover shows scale, but two businesses with the same sales can have very different margins, investment needs and risks. Revenue multiples may be relevant in some circumstances, but the revenue definition, comparability and path to cash generation need support. A generic turnover rule should not replace that analysis.
If you are preparing an exit, see our business valuation before selling guide. For a written conclusion, compare the scope of a business valuation report.
A valuation basis is different from a method
The basis defines the value question; the method is how the analysis addresses it. Before calculating, identify the business or interest, valuation date, purpose, intended users and relevant assumptions. A current sale discussion and a historical share transfer may require different instructions even where both start with the same accounts.
Also distinguish a continuing business from a scenario involving the disposal of assets. A forced or restricted sale is not simply the same exercise with a smaller multiple. Explain the circumstances and obtain appropriate legal, tax or specialist instructions where the assignment needs them.
A useful brief could say: ‘We need a current assessment of the ordinary shareholding for an ownership discussion, based on the rights in the supplied documents.’ That is more informative than asking for a certified number without defining its intended use.
Market-based valuation: compare the full transaction
A market approach uses relevant evidence from comparable companies, transactions or dealings in the subject company. A quoted multiple is only an input. Check the business size, earnings definition, period, growth, concentration, financing and commercial circumstances before deciding whether the comparison is useful.
For a hypothetical comparison, a price may include deferred or contingent consideration while another is payable entirely at completion. The same headline multiple can therefore describe different economics. Likewise, a multiple of enterprise value to EBITDA should not be applied as though it were an equity-value multiple to post-tax profit.
Record why an observation is relevant and where information is missing. Selecting the median from a list does not cure weak comparability. Ask the adviser to explain the chosen method and cross-check rather than provide a universal sector multiple before reviewing the business.
How to turn the methods into a practical valuation process
- Define the question: subject, date, purpose, rights and intended use.
- Reconcile the evidence: accounts, current trading, ownership and financial position.
- Analyse maintainable performance: examine supported earnings adjustments and continuing costs.
- Select relevant methods: connect each method to the business and available evidence.
- Reconcile the conclusion: distinguish operating value, equity, a specific holding and transaction proceeds.
- Explain uncertainty: show material sensitivities, limitations and the circumstances requiring an update.
Do not average unrelated results merely to remove a disagreement. A method can be a cross-check without carrying equal weight. Read the detailed asset-based valuation worked example and the guide to rule-of-thumb valuations to see why method selection needs more than a formula.
Your starting checklist.
- Stable or changing trading performance
- Forecast reliability and investment needs
- Relevant asset values and obligations
- Evidence supporting any comparable multiple
Start with the purpose. Confidential documents can follow through an agreed channel.
Further questions
What is the simplest way to value a small business?
A simple earnings or asset calculation can illustrate mechanics, but it does not establish a reliable company-specific value. Define the purpose and evidence first, then select an appropriate method.
Can I use a rule of thumb based on turnover?
Turnover alone does not show sustainable earnings, cash needs or the rights being valued. Investigate any sector rule and its evidence before using it in an assessment.
Is valuation basis the same as valuation method?
No. The basis defines the value question and assumptions; a method is a technique used to address that question with the available evidence.
