A business is usually valued by multiplying its sustainable earnings, the normalised profit after adjusting for owner add backs, by a market multiple that reflects its industry, size and risk. Other methods include discounted cash flow for growing businesses and asset based valuation for asset heavy ones. In practice the answer is a defensible range, not a single number, and what drives it is risk and how much the business depends on you.
Most owners have a number in their head for what their business is worth, and most are wrong, in both directions. Value is not what you have put in, or what you would like to retire on. It is what a rational buyer will pay for the future profit and the risk that comes with it. In our experience working with owners approaching a sale or a restructure, understanding what drives the number early is worth far more than a valuation done the month before you exit. Mina Baselyous, a Chartered Tax Advisor (CTA), CPA and Registered Tax Agent, advises owners on valuation, structuring and exit. This guide explains the methods, what really moves the figure, and how to lift it before you sell.
What is a business valuation and why it matters
A business valuation is an estimate of what your business is worth to a buyer at a point in time. It matters well before a sale: it underpins succession and exit planning, buying in or out a partner, raising finance, settling disputes, and meeting tax obligations. Knowing your number, and what moves it, turns vague ambition into a plan you can actually manage toward.
Valuation is also a management tool, not just an exit event. The same factors that lift a sale price, strong recurring revenue, low owner dependence, clean records and predictable growth, are the factors that make a business better to own today. That is why we treat valuation as connected to everyday performance and Virtual CFO work, not a one off number pulled together at the end. If you are buying rather than selling, the same logic drives price on the other side of the table, as covered in our guide to buying a business in Australia.
The main valuation methods
There are three common approaches. The earnings multiple method, most common for established small and medium businesses, applies a multiple to normalised profit. Discounted cash flow values a business on the present value of its expected future cash flows, and suits businesses with strong, forecastable growth. Asset based valuation totals the net assets, and suits asset heavy or winding down businesses rather than profitable trading ones.
For most owner operated businesses, the earnings multiple approach dominates because it is how buyers actually think: what is the sustainable profit, and how many years of it am I willing to pay for. Discounted cash flow is more rigorous but only as good as the forecasts behind it, so it is used for higher growth or capital intensive businesses. Asset based valuation usually sets a floor rather than the answer, because a profitable business is worth more than the sum of its equipment. A proper valuation often cross checks two methods to land on a range.
What actually drives the number
Two businesses with identical profit can be worth very different amounts. The driver is risk: the more certain and transferable the future earnings, the higher the multiple a buyer will pay. The biggest levers are owner dependence, revenue quality, customer concentration, growth trend, and the reliability of the financial records behind the numbers.
Start with normalised earnings. Buyers strip out owner add backs (personal expenses, above or below market owner wages, one off items) to find the true, ongoing profit, so clean, defensible accounts matter. Then they price the risk: a business that runs without the owner, earns recurring or contracted revenue, has no single customer above roughly ten to fifteen percent of sales, and shows a steady growth trend commands a materially higher multiple than one that is really a job with the owner at the centre. As Mina Baselyous (CPA, CTA) says, the fastest way to raise your valuation is not to grow profit by ten percent, it is to make the same profit far less dependent on you.

Book a ConsultationWhat is a multiple, and what is a good one?
A multiple is simply how many years of normalised earnings a buyer will pay. If a business earns $400,000 in normalised profit and sells on a multiple of three, it is worth around $1.2 million. Small owner operated businesses commonly trade on lower multiples, while larger, more systemised businesses with lower risk attract higher ones.
There is no single correct multiple; it reflects risk and size. As a broad pattern, small businesses that depend heavily on the owner often sell in the region of two to three times earnings, while larger, well systemised businesses with recurring revenue and a real management team can command four times or more. Industry norms matter too. The point is not to memorise a number but to understand that you influence your multiple: every risk you remove from the business moves it up. This is where planning to build a business that runs without you pays off directly at sale.
How to increase your valuation before you sell
The best time to lift your valuation is two to three years before you sell, not the week you list. The highest impact moves are reducing owner dependence, building recurring or contracted revenue, diversifying your customer base, cleaning up your financial records, and showing a consistent growth trend. Each one lowers buyer risk and lifts the multiple.
Practically, that means documenting systems so the business does not live in your head, promoting or hiring a second in charge, converting one off sales into retainers or contracts where possible, and getting your bookkeeping and reporting to a standard a buyer can trust in due diligence. Accurate records are the foundation: no buyer pays a premium for numbers they cannot verify. This is exactly the forward work a Virtual CFO engagement drives, and it dovetails with getting your structure right so the eventual sale is tax efficient through the small business CGT concessions.
When you need a formal valuation
A formal, independent valuation is worth the cost when the number carries real consequences: selling the business, admitting or exiting a partner, a divorce or dispute, raising finance, or meeting a tax obligation. Several tax outcomes, including the small business CGT concessions, depend on defensible market values, so a rough estimate is not enough.
The small business CGT concessions, for example, apply where the business has aggregated turnover under $2 million or maximum net asset value under $6 million as at the 2025-26 year (see the ATO small business CGT concessions), and the ATO expects values to be supportable, so market valuations for tax must follow the ATO valuation guidelines. For a sale, a defensible valuation also anchors your negotiation. Whether you are years from exit or preparing to sell now, understanding the number early lets you plan around it. It connects directly to selling your business and to proactive tax planning.
Frequently Asked Questions
How do you value a small business in Australia?
Most small businesses are valued by multiplying normalised earnings, the sustainable profit after adjusting owner add backs, by a market multiple reflecting the industry, size and risk. Larger or high growth businesses may use discounted cash flow, and asset heavy ones use an asset based method. The result should be a defensible range, not a single figure.
What multiple do businesses sell for?
It depends on size and risk. Small owner dependent businesses often sell around two to three times normalised earnings, while larger, systemised businesses with recurring revenue and a management team can attract four times or more. There is no fixed number; the multiple reflects how certain and transferable the future earnings are.
What are add backs in a business valuation?
Add backs are adjustments that restate the reported profit to its true, ongoing level. They include personal expenses run through the business, owner wages above or below market rate, and one off or non recurring items. Normalising for add backs gives the sustainable earnings a buyer will actually pay a multiple on.
How can I increase the value of my business before selling?
Reduce how much the business depends on you, build recurring or contracted revenue, diversify your customers, show a consistent growth trend, and get your financial records to a standard a buyer can verify. Each of these lowers buyer risk and lifts the multiple. Start two to three years before you sell for the best result.
Do I need a formal valuation, or is an estimate enough?
An estimate is fine for planning, but you need a formal, independent valuation when the number has consequences: selling, a partner buy in or out, a dispute, raising finance, or a tax position such as the small business CGT concessions, where the ATO expects supportable market values that follow its valuation guidelines.
