Key takeaways
Define the value you actually need.
The operating business, its assets and your shares are different valuation subjects. Establish the purpose and date before asking for a number.
Sustainable earnings matter more than headline turnover.
Consider commercial owner replacement costs, unusual items and the investment needed to keep trading. Revenue alone cannot establish value.
Risk and transferability shape what earnings are worth.
Customer concentration, owner dependency, contracts and premises security affect the durability of the business a new owner would acquire.
Business value is not automatically your sale proceeds.
Debt, cash, working capital, transaction terms and the rights being sold can change the amount attributable to the owners.
Use estimates to ask better questions—not settle major decisions.
A calculator cannot verify your records or assess every material risk. A consequential decision needs a defined scope and a traceable explanation.
What is my business worth? Start with the business someone can acquire
Your business is not worth a fixed percentage of turnover simply because another business sold on that basis. A useful assessment asks what economic benefits the business can sustain, what risks attach to those benefits, and what actually transfers with the interest being valued.
That distinction matters when you have spent years building the business. Your effort, reputation and investment explain its history; they do not, on their own, establish the value another owner could obtain. The question is not just “What have I put in?” but “What remains commercially useful when ownership changes?”
The Australian Government’s business valuation guidance describes several approaches rather than a single universal formula. This article focuses on the factors behind the number. If you are weighing up a broker’s appraisal against a formal valuation, the difference between the two documents matters more than most owners expect. For the assessment process itself, read how to value a business in Australia.
First decide what the number is meant to represent
An operating business, a collection of assets and a parcel of company shares are different subjects. A valuation for sale planning may also have different instructions from a valuation supporting a shareholder exit or tax matter. Specify the subject, purpose and valuation date before comparing figures.
Ask three questions: Which entity earns the income? Which assets and obligations are included? Whose interest is being valued? Premises owned outside the trading entity, shareholder loans and restricted ownership rights can change the answer. A headline “business value” without those boundaries may not describe what you own or intend to sell. The appropriate basis of value also depends on the purpose of the valuation and the interest being assessed.
For most established, profitable businesses, sustainable earnings are more informative than turnover
Revenue shows trading activity, not the profit available after the resources needed to operate have been paid for. Two businesses with similar sales can have very different margins, staffing needs, investment requirements and customer retention.
Recorded profit also needs interpretation. Owner remuneration, related-party rent and genuinely unusual income or expenses may need adjustment. The adjustment must reflect commercial reality: if you perform sales, delivery and management duties, those functions do not become free when you leave.
Before relying on an earnings figure, ask whether it allows for the work required to keep earning it. Deferred equipment replacement or an unusually favourable rent arrangement may make current results look stronger than the ongoing economics. Our EBITDA guide explains why a headline earnings multiple is not a complete assessment.

Signed
A clear valuation conclusion starts with an agreed purpose, relevant evidence and disclosed assumptions. The report identifies the interest valued and explains the reasoning behind its conclusion.
Risk determines how dependable those earnings are
A profit stream tied to one customer, one supplier or one owner is different from a diversified operation with documented systems. Consider both the likelihood of disruption and the cost of responding to it.
Evidence worth examining includes:
These are not automatic percentage deductions. Their significance depends on the business, the valuation basis and the evidence. The useful question is how each issue affects maintainable earnings, future cash flows or the risk attached to them.
Revenue and margin concentration by customer or contract, using de-identified records where possible.
Contract renewal dates, termination rights and any consent needed on a change of ownership.
Key staff responsibilities, owner involvement and realistic replacement arrangements.
Premises tenure, lease options and material equipment or maintenance requirements.
Forecast assumptions supported by actual capacity, contracts and trading experience.
Can the goodwill continue without you?
Goodwill may arise from an established customer base, reputation, systems or other advantages supporting future economic benefits. But a relationship attached personally to the owner may not transfer in the same way as a business-owned contract or functioning team.
Imagine two otherwise similar firms: one routes all enquiries, quoting and delivery through its founder; the other has experienced staff, documented processes and customer relationships held by the firm. This is a qualitative illustration, not a priced case study. It shows why similar past profits do not necessarily imply equal transferability.
Do not assume goodwill is an extra amount to add after valuing an earnings stream. An earnings-based conclusion may already reflect the economic benefits associated with goodwill and operating assets. The treatment must be explained to avoid counting the same value twice.
Worked comparison: the same headline profit, different economics
Consider two fictional businesses that each report $250,000 EBITDA. These numbers are made up for explanation, not extracted from a client report. Business A's accounts already include the full cost of management performed by employees. Business B depends on an owner whose recorded remuneration is assumed to be $60,000 below the supported full cost of replacing those duties. With all other adjustments set aside for this illustration, B's adjusted earnings become $190,000, while A remains at $250,000. The additional $60,000 represents replacement management costs not already included in Business B's reported EBITDA, so the adjustment does not double count anything already recognised.
That is a difference in the earnings available after necessary work is paid for—not an automatic $60,000 difference in business value. A valuation still needs an appropriate method and evidence. It would be misleading to apply a generic multiplier to both recorded figures and declare the businesses equally valuable.
Now consider transferability separately. Assume A's recurring work is held under business contracts, while B's customers depend on personal introductions and have not agreed to stay after an ownership change. Those hypothetical facts require investigation of retention, contract rights and transition costs. They do not justify inventing a standard goodwill discount. Equally, A's contract renewal terms could expose risks that its headline profit conceals.
Use the comparison to ask better questions: Which duties must be replaced? What does replacement actually cost? What evidence supports customers remaining? Read the worked earnings and equity examples for the arithmetic behind these distinctions. The outcome for your business depends on its own records, rights and instructed valuation basis.
Business value is not automatically what you take home
The value of operations is not necessarily the value of the owners’ equity. Relevant debt, cash, non-operating assets and working-capital assumptions need to be reconciled consistently with the method and transaction boundary.
A negotiated sale may also involve staged payments, retention conditions, handover obligations or a buyer’s particular synergies. Transaction costs and tax can affect net sale proceeds. Their treatment in the valuation itself depends on the valuation basis, subject and circumstances. A valuation is an informed reference point, not a promise of a buyer, an offer or a completed sale at that amount.
If shares are the subject, the rights of the holding matter too. A minority interest is not automatically an identical fraction of a controlling business value. See private share and trust unit valuations.
What can you do before commissioning a valuation?
Prepare a short evidence pack: financial statements across relevant periods, current management accounts, debt and asset schedules, ownership details, major contracts and a description of your own role. Explain material changes rather than sending only your strongest trading year.
Then identify the decision you need to make. Is it sale readiness, an ownership exit, succession planning or an adviser-defined tax requirement? That decision determines how much analysis and reporting is appropriate. For a sale, selling-a-business valuations can be scoped around the proposed transaction.
A calculator or rule of thumb can prompt questions, but it cannot verify accounts, read every agreement or test the business’s transferability. This article does not provide an automated valuation or a numerical industry benchmark. For a consequential decision, request a documented assessment with clear assumptions and limitations. Current Fixed Professional Fees should be checked against the proposed scope.
Frequently asked questions
How much is my business worth if I know its annual turnover?
Turnover alone is insufficient. The analysis also needs margins, sustainable earnings, operating costs, investment needs and risk. A revenue comparison only helps when its definitions and underlying evidence are relevant.
Is the value of my business the same as its sale price?
Not necessarily. A valuation answers a defined question at a specified date. Negotiated price can reflect deal terms, competing offers, buyer-specific benefits and financing arrangements.
Does the latest profit tell me what the business is worth?
It is one input, not a complete answer. Review whether the period is representative and whether owner costs, unusual items and required ongoing expenditure are reflected appropriately.
Can I add all my salary back to profit?
Not automatically. Identify the duties you perform and what it would cost to replace them. An adjustment that ignores necessary replacement work can overstate sustainable earnings.
How does customer concentration affect value?
Dependence on a small number of customers can make earnings more vulnerable to contract loss or changed terms. Assess the actual contracts, retention evidence and effect on cash flows rather than applying an unexplained standard discount.
Is goodwill included in the valuation?
It depends on the subject and approach. An earnings-based conclusion may already capture benefits associated with goodwill. Adding a separate goodwill amount without reconciliation risks double counting.
Do debts reduce the value of my business?
Distinguish operating business value from owners’ equity. Debt and cash need treatment consistent with the chosen method and scope; a quoted operational value is not automatically net owner proceeds.
Can an online calculator give me a reliable sale price?
A calculator can provide an indicative output from assumptions, but cannot establish buyer demand or verify all relevant records and risks. Do not treat its output as a formal valuation or guaranteed sale price.
Can I value the business at an earlier date?
A historical instruction may be possible with appropriate evidence from that period. Today’s performance should not simply be projected backwards. See retrospective valuation evidence.
What should I tell a valuer in my first enquiry?
Describe the entity or interest, reason for the valuation, relevant date, intended users and any deadline. Explain whether records are available; avoid sending sensitive client information in an initial message.
