How much is a business worth? Methods and practical tips

Determine how much a business is worth in Portugal is one of the most decisive steps — whether for those considering selling or for those analysing a buying opportunity. Two companies with the same turnover can reach very different conclusions if the margin, cash generation, debt, customer concentration, or founder dependency are different.

This guide explains the difference between value, price and conditions, the main valuation methods (multiples, DCF and assets), the factors that most affect the value of an SME and what to gather before negotiating. It does not calculate the value of a specific business. For an indicative estimate based on your data, use the business valuation evaluator/simulator from ComprarEmpresa — a complementary tool to this guide, not a substitute for professional valuation.

If you already know what you are looking for in the market, you can explore businesses for sale or advertise the sale confidentially.

Value, price and conditions are not the same thing

In the realm of business transfer, three concepts go hand in hand — and confusing them can be costly at the negotiation table.

• Value is an analytical reference. It is based on the company's ability to generate future wealth, the quality of the assets, and the level of risk associated with the continuity of operations. It is an estimate built from information, assumptions, and a perspective on the business.

• Price is the amount for which the transaction is actually closed. It results from the agreement between the parties, the urgency of each side, and the market dynamics at that moment.

• Conditions are the structure of the deal: what is included, which debts remain with the company, when payment is made, what guarantees exist, and whether part of the payment is linked to future results (earn-out or similar mechanisms).

In practice, two proposals with the same announced number may not have the same economic meaning. One may be paid at closing, with fewer obligations. Another may depend on future results or transfer more risk to the seller. Comparing only the face value says little.

The main valuation methods

There is no single correct method — professionals often cross-reference several and compare the results. Typically, it is considered from three complementary perspectives: income (cash), market references, and assets. In SMEs, these lenses translate into the methods below.

Market multiples (valuation based on profit)

This is the most common approach in SMEs. It involves applying a multiple to a measure of results — typically EBITDA or profit — based on what similar companies in the same sector are usually worth. It provides a quick estimate relative to the sector, but only makes sense with real comparables.

The appropriate multiple varies with the activity, size, margin, and risk of the business. This article does not publish invented sector multiples: use real references and validate with those who know the market — or start with an order of magnitude in the valuation simulator.

Discounted cash flow (DCF)

The discounted cash flow method estimates the present value of expected future cash flows, applying a discount rate that reflects the risk. It is useful for companies with positive and predictable cash flow, but it is sensitive to assumptions: small changes in projections or in the rate can significantly alter the result. Use it with realistic, not optimistic, projections.

Asset-based valuation

Here the value starts from the net assets — assets minus liabilities. It makes sense in companies with many tangible assets (equipment, real estate, inventory) or in scenarios of cessation of activity. It tends to undervalue the 'going concern' business (brand, customer portfolio, history), so it should rarely be used in isolation for a profitable business.

Practical summary: cross at least two lenses. A market reference serves to ask better questions, not to apply an automatic number to any SME.

Financial analysis: the basis of any valuation

A serious valuation starts with the accounts. They confirm whether the company actually earns what it claims to earn and whether that result is sustainable.

• Financial statements — examine the balance sheet, income statement, and cash flow for the last three to five years. Look for consistency in profits, revenue growth, and expense control. Sharp fluctuations or atypical years should be explained.

• Indebtedness — high liabilities increase risk, especially if profits do not comfortably cover financial obligations. Distinguish between debt that finances growth and debt that merely plugs cash flow gaps.

• Margin and cash — revenue alone says little. What matters is recurring profitability and how much of that profitability turns into cash after normal operational needs.

To frame the total budget of the operation (in addition to the company's price), also see how much it costs to buy a business.

Factors that most affect value

These are some of the factors that weigh most in the conversation between buyer and seller of SMEs in Portugal:

• Normalized EBITDA — adjusted operating profit. Normalization qualitatively isolates extraordinary expenses, personal costs of partners, or remuneration outside market reality, to bring recurring profitability of the operation closer.

• Debt and liabilities — the financing structure impacts the net value of the transaction. High liabilities, contingencies, or demanding guarantees reduce flexibility.

• Customer concentration — revenue highly dependent on a few customers increases the risk of continuity.

• Founder dependency — if decisions, business relationships, and critical knowledge are centred on one person, transferability is low.

• Revenue recurrence — retainers, long-term contracts or stable relationships provide more cash visibility.

• CAPEX and investment needs — businesses that require constant renewal of equipment, fleet or systems generate less available cash for investors.

• Contracts, licenses and ownership — brands, licenses or exclusive contracts can act as barriers and increase strategic value.

• Global operational risk — turnover of key personnel, single suppliers or weaknesses in the supply chain add uncertainty.

Revenue, in isolation, says little. The market tends to value the sustainability of results and conversion into cash — not just the top of the income statement.

Value for the seller vs value for the buyer

For the founder, the value often incorporates historical effort, personal sacrifices and emotional attachment to the brand. For the buyer, the lens is future return and operational risk mitigation. Neither side is 'wrong' for starting from different places — but negotiation only progresses when it focuses on the transferability and the objective evidence of continuity.

If you are preparing for exit, organise the dossier with the guide preparing the company for sale and the steps to sell a business. If the operation involves the acquisition of shares in an Lda, the guide transfer of shares helps frame the structure — without replacing legal advice.

Due diligence: validate the value on the ground

The financial assessment must be validated on the ground. Confirm legal compliance, relevant litigation, relationships with customers and suppliers (pay attention to excessive dependence on one) and the dependence on the current owner. Also understand why the owner is selling: retirement or life change are common; a sale motivated by business problems requires deeper investigation.

Use the due diligence checklist as a guide by area (financial, tax, labour, legal, operational and commercial). The numbers and risks validated in the diligence feed into a substantiated price — due diligence does not replace the assessment, and the assessment alone does not replace diligence on liabilities and contracts.

Checklist before forming a value expectation

Before requesting an estimate, using the simulator or sitting at the table, gather information that allows you to confirm results and obligations. The list below is a practical starting point — adapt it to the sector and validate with an accountant or consultant. Do not invent multiples or generic 'market values' from this checklist.

• Recent financial statements and, if possible, a history of three to five years.

• Details of financial debt and other relevant commitments.

• Note on customer concentration (and stability of relationships).

• Map of the key team and degree of dependence on the founder/management.

• Contracts, licenses and obligations that support the activity.

• Inventory/relevant assets and condition.

• CAPEX and planned investment to maintain or grow the operation.

• Known contingencies (litigation, guarantees, open tax or labour liabilities — to be clarified with professionals).

• Clarification of what is included in the transaction (shares, establishment, assets) and what is excluded.

• Clear hypothesis of the desired conditions (payment schedule, earn-out, transition period).

The clearer the information, the more useful the discussion about value will be — and the lower the likelihood that the price will need to be revised late in the process.

Simulator vs guide: how to use each one

This guide structure literacy: what is value, what methods exist, what influences the outcome and what to ask. The business valuation simulator from ComprarEmpresa is the tool to obtain a indicative estimate based on inputs (for example turnover and EBITDA), using the benchmark logic employed by the tool.

Use them in natural sequence:

1. Read this guide and complete the minimum information checklist.

2. Run the valuator for an indicative order of magnitude.

3. Validate data and risks with due diligence and professionals before making commitments.

The estimate from the simulator does not replace a professional valuation or the analysis of the specific conditions of the transaction. It is a starting point — aligned with the warning from the tool itself.

Also remember: the value of the company is not the same as the total cost of buying (taxes, advisory, working capital, post-purchase investments). For that angle, see how much it costs to buy a business.

Mistakes to avoid in valuation

• Basing the value on a single method — always cross-check with at least two lenses.

• Relying solely on the numbers provided by the seller without validating them.

• Ignoring hidden liabilities, contingencies and founder dependency.

• Evaluate solely based on turnover, without margin, cash, and debt.

• Let emotion or calendar pressure guide the number.

• Confuse face value with the real economic conditions of the proposal.

• Treat the simulator's result as the final market price.

A careful evaluation helps to reduce the common risks in buying businesses..

Frequently asked questions about how much a business is worth.

How much is my business worth?

Value does not follow a fixed rule. It depends on the ability to generate cash flows sustainably, the predictability of turnover, the level of debt, and risk factors such as customer concentration and founder dependency. Each case requires individual analysis — start with the simulator and validate with professionals.

What is the difference between value and price?

Value is an analytical estimate (results, assets, risks, assumptions). Price is the amount agreed upon in the transaction. Between the two are the conditions — timing, debt, guarantees, earn-out — that can make the same nominal number have different economic meanings.

Does this guide calculate the value of my business?

No. This guide is educational and qualitative. It does not generate individual evaluations nor replace the analysis of your data. For an indicative online estimate, use the business evaluator..

How is the value of a business assessed?

The value is assessed by crossing financial analysis with one or more methods — market multiples, discounted cash flow (DCF), and asset-based valuation — and adjusting with qualitative factors (market, customers, owner dependency). The goal is a defensible range, not a single absolute number.

Can I evaluate a business solely based on turnover?

Not with precision. Turnover does not show margin, cash generated, debt, necessary investment, or revenue quality/recurrence. It is a starting point for investigation, not a conclusion.

What is profit-based valuation?

It is the multiples approach: a multiple is applied to a measure of results (usually EBITDA or profit), referencing similar businesses. It is the most commonly used method in SMEs due to its simplicity, but the correct multiple depends on the sector, size, and risk — this article does not publish invented multiples.

Is there a 'correct' or universal EBITDA multiple?

No. Multiples only make sense with real comparables. The ComprarEmpresa simulator applies its own reference logic — treat the result as indicative and confirm with professionals.

Does debt influence the analysis?

Yes. It is essential to understand that debt and obligations exist, who assumes them in the operation, and how this reflects on the price and conditions. Hidden or poorly mapped liabilities are one of the main causes of late price revision.

Is the value the same for the seller and the buyer?

Often not. The seller incorporates history and effort; the buyer focuses on return and risk. Alignment involves evidence of transferability, clear data, and transparent conditions.

What should I prepare before discussing value or using the simulator?

Gather accounts, debt details, customer information, relevant contracts, CAPEX notes, and clarity on what is included in the transaction. Use the checklist from this article; then the simulator; and, before commitments, due diligence and professional advice. If the goal is to buy, see how to buy a business. If it is to sell, sell a business with confidentiality.

Next step

Recapping: value, price and conditions are not the same thing; the methods (multiples, DCF, assets) and operational factors (normalized EBITDA, debt, customers, founder, CAPEX) weigh as much or more than revenue. This guide educates — the valuation simulator provides an indicative estimate; the decision requires data and professionals.
