Business Valuation: A Complete Guide
Three approaches, multiples, discounts, and what actually moves the final number.
Three approaches, multiples, discounts, and what actually moves the final number
The question "what is my business worth" comes up in several situations: a sale, a partner buying in, raising investment, a divorce or inheritance, one co-owner exiting. And the answer almost always turns out to be more complicated than expected.
A business does not have one correct price. It has a range, within which different methods produce different results, and the final figure depends on who is buying, why, and on what terms. This guide is about how to build that range and what pushes it in either direction.
Three approaches to valuation
All valuation practice rests on three approaches. They do not compete, they complement each other: a serious valuation uses at least two and compares the results.
Income approach
The most common for an operating business. The logic: a company is worth the money it will generate for its owner in the future.
There are two main methods within this approach.
The multiples method. A profit figure is taken and multiplied by a coefficient typical for the industry.
Value = Profit measure × Multiple
The base is most often earnings before interest, tax, depreciation and amortisation. For very small businesses where the owner works actively in the company, seller's discretionary earnings are often used instead, meaning profit plus the owner's compensation plus one-off costs.
Discounted cash flow. A forecast of free cash flow is built for five years or more, each year is discounted back to present value, and everything is summed together with a terminal value.
Value = Σ (Cash flow year N / (1 + rate)^N) + Terminal value
The method is more precise in theory but extremely sensitive to assumptions: changing the discount rate by two percentage points can move the result by a third. For small businesses it is used less often than multiples, and usually as a cross-check.
Market approach
The logic: a company is worth what comparable companies are worth.
A sample of transactions involving businesses of the same profile, size and geography is collected, multiples to revenue or profit are derived from them, and those multiples are applied to your company.
The main problem with this approach for small businesses: there is little data, and what exists is often not comparable. A transaction involving a company in the same industry but twice the size, with a different client structure and in a different country, provides limited information.
The market approach works well as a sanity check. If your income-based valuation implies a multiple of 12 while deals in the industry close at 5, you need an explanation for why your company is worth twice as much.
Asset approach
The logic: a company is worth what it would cost to recreate its assets, or what could be realised by selling them separately.
Value = Market value of assets – Liabilities
For most service and technology companies this approach produces the lowest figure and is barely used: the value there sits in the client base, the teams and the processes, not in property.
It is relevant in two situations: when the business is asset-heavy, meaning the value is in real estate and equipment, and when the company is loss-making and the question is liquidation value.
Which measure to use as the base
The choice of base for the multiple depends on the size and type of business.
Revenue. Used when profit is negative or structurally suppressed by investment in growth. Typical for product companies in a scaling phase. Revenue multiples depend on growth rate and customer retention.
Earnings before interest, tax, depreciation and amortisation. The standard for mid-sized companies with normal profitability. It strips out differences in tax regimes, financing structure and accounting policy, which makes companies comparable.
Seller's discretionary earnings. Used for small businesses where the owner is the main operator. Profit is adjusted by adding back the owner's salary, personal expenses run through the company, and one-off atypical costs. The logic is that a buyer will have that money at their disposal.
Net profit. Rarely used, mostly for stable debt-free companies where the buyer's tax structure will be the same.
Indicative multiples
The figures below are ranges, not precise values. A specific transaction can fall outside them in either direction.
| Type of business | Multiple to profit |
|---|---|
| Small service business dependent on the owner | 1.5–3x |
| Local business with its own client base | 2–4x |
| Mid-sized manufacturing | 4–6x |
| Technology service business | 4–8x |
| Company with a subscription revenue model | 6–12x |
The general pattern: the larger the business, the higher the multiple. A company with $200,000 in profit and a company with $5 million in profit in the same industry are valued at different coefficients, because the larger business is more resilient, less dependent on individuals, and accessible to a wider pool of buyers.
What increases value
Client diversification. A company where the largest client accounts for 15% of revenue is worth noticeably more than a company with the same profit where one client accounts for 60%. In the second case the buyer is acquiring the risk of losing most of the business along with a single contract.
Revenue predictability. Long-term contracts, subscriptions and repeat orders are valued higher than one-off projects. The buyer pays for certainty about future cash flows.
Independence from the owner. This is one of the largest factors in small business. If sales, key relationships and major decisions all run through the owner, the business drops after their exit, and the buyer prices that in. A company with a functioning management team is worth substantially more.
Growth rate. A company growing 30% a year earns a higher multiple than a company with the same profit standing still. The buyer pays for the future, not the past.
Quality of financial reporting. A company with transparent management accounts, comparable data across three years and an explainable cost structure clears due diligence faster and gets better terms. A company where accounting was partial and the data has to be reconstructed invites suspicion and a discount.
Legal cleanliness. Properly held intellectual property rights, correct agreements with key employees, no disputes or tax exposure. Every problem here either lowers the price or blocks the deal.
What decreases value
Concentration in one client or supplier. The mirror image of diversification.
Staff turnover. In businesses where value sits in people, high turnover means the buyer acquires vacancies rather than a team.
Declining trajectory. A company whose revenue has fallen for two consecutive years is valued significantly lower, even if current profit is normal.
Dependence on a single acquisition channel. If all traffic comes from one source, a change in that source's algorithm or policy can zero out sales.
Deferred investment. Ageing equipment, technical debt, a system that needs replacing within the year. The buyer will cost these out and deduct them from the price.
Opacity. Cash transactions outside the books, owner expenses mixed with business ones, missing documentation. Even if everything is honest, the buyer cannot verify it and prices in the risk.
Enterprise value versus equity value
An important distinction that frequently gets confused in negotiations.
Enterprise value is the valuation of the operating business, regardless of how it is financed.
Equity value is what the buyer actually pays the owner.
Equity value = Enterprise value – Net debt + Excess working capital
Example: the parties agree an enterprise value of $4 million. The company has a $600,000 loan and $150,000 in the bank. Net debt is $450,000. The owner receives $3.55 million, not $4 million.
So "we valued the company at four million" does not mean the seller walks away with four million. This always needs clarifying.
Working capital in a transaction
A separate topic that often surfaces late and damages agreements.
The buyer is acquiring a business that has to keep operating from day one. For that, it needs to retain a normal level of working capital: inventory plus receivables minus payables.
Most transactions fix a target working capital level, calculated as the average over the last twelve months. If the actual level at closing is below target, the price is reduced by the difference. If above, it increases.
This is a standard mechanism, but it regularly becomes a point of dispute, because a seller approaching closing naturally tries to collect receivables and delay paying suppliers, which pulls cash out of working capital.
Discounts applied to valuation
After the base calculation, discounts may be applied to the value.
Discount for lack of control. If the stake being sold does not confer control, it is worth less than a proportionate share of the whole. The typical range is 15% to 30%.
The logic: an owner of 25% cannot decide on dividends, asset sales or strategy, so their stake is less valuable than a quarter of full control.
Discount for lack of marketability. A stake in a private company cannot be sold quickly, unlike listed shares. The discount can run from 20% to 35% for small businesses.
Key person discount. If the business is critically dependent on one individual, an additional discount of 10% to 25% applies.
These discounts can compound. Valuing a minority stake in a small company dependent on its founder can easily come out at half the proportionate share of total value.
What the process looks like in practice
Step 1. Getting the accounts in order. Three years of management accounts in a consistent structure. If the bookkeeping was irregular, this is the longest stage and needs to start well in advance.
Step 2. Normalising profit. One-off income and costs are stripped out, owner expenses unrelated to the business are removed, and costs for roles that are currently unpaid are added in. The goal is a figure that reflects sustainable profitability.
Step 3. Calculating by several methods. At least two approaches: multiples plus discounted cash flow or market comparables. The results should land in the same range. If they differ by multiples, an assumption is wrong somewhere.
Step 4. Adjusting for company-specific factors. Diversification, owner dependence, trajectory, quality of accounting. This shifts the multiple within the industry range.
Step 5. Applying discounts. If a stake is being sold rather than the whole business.
Step 6. Producing a range. The output of a valuation is not a single number but a range within which negotiation happens.
Common valuation mistakes
Valuing on revenue when the business is profitable. Revenue does not show what the business earns. Two companies with the same revenue and different margins are worth different amounts.
Borrowing a multiple from another industry. Technology company multiples do not apply to a service business, and vice versa.
Failing to normalise profit. If the most recent year contained one large exceptional deal, or conversely one large exceptional cost, a valuation based on that year will be distorted.
Ignoring working capital and debt. Agreeing an enterprise value without discussing the mechanism for calculating net debt and target working capital almost guarantees conflict at closing.
Valuing on forecast rather than actuals. The seller believes the company is worth its future performance, the buyer pays for what has been achieved. The forecast influences the multiple, but the base is actual figures.
Confusing valuation with price. Valuation is a calculation. Price is the result of negotiation, and depends on how many interested buyers there are, how urgent the sale is, and how strategically valuable the company is to a specific buyer. A strategic buyer for whom your company closes a specific gap may pay considerably more than the calculated value.
When you need a professional valuation
A self-prepared calculation is sufficient for understanding the order of magnitude, preparing for negotiations and internal planning.
An independent valuation is needed when the result carries legal consequences: litigation, division of assets, a member exiting under a statutory procedure, contributing a stake to share capital, valuation for tax purposes.
It is also usually required when raising institutional investment or bank financing secured against a stake.
Summary
Valuing a business is not a search for the single correct number but the construction of a defensible range.
It starts with getting the accounts in order and normalising profit, because without that any method will produce an unreliable result. Then at least two approaches are applied, the results are compared, and the difference between them is explained.
The largest influence on the final figure in a small business comes not from the calculation method but from the characteristics of the company itself: how dependent it is on the owner, how diversified the client base is, how predictable the revenue, and how transparent the accounting. Working on those factors a year before a sale affects the price more than the choice of valuation method.
