Valuing a business

Although there are several formulas you can use, there are no black-and-white answers on valuation techniques.

It’s important to conduct your own research, then get independent advice from a business valuer or broker. Here are four of the most commonly used valuation methods:

  1. Asset valuation
  2. Capitalised future earnings
  3. Earnings multiple
  4. Comparable sales  

  • Adds the value of the assets of the business and subtracts its liabilities
  • Determines what the business would be worth if it were closed down today and sold
  • Doesn’t take into account the ability of those assets to generate wealth in the future
  • Doesn’t take into account goodwill
  • For these reasons, asset valuation may understate the true value of the business 

How it works

  • Add up the value of all the assets such as cash, stock, plant and equipment and receivables
  • Add up liabilities, such as any bank debts and payments due
  • Subtract the liabilities from the assets to get the net asset value


  • Richard wants to buy a manufacturing business. Here’s an extract from the balance sheet:

An extract from the balance sheet.
  • The business has $300,000 of assets and $200,000 of liabilities
  • The net asset value is $100,000

What about goodwill?

  • Goodwill is the difference between the true value of a business and the value of its net assets
  • It can be crucial to the value of retail and service-based businesses
  • Asset valuation doesn’t include a value for goodwill, so may understate the true value of a business
  • For example, if you value a hair salon, where service, location and reputation are important, the value of any goodwill would have to be added to net assets to get a valuation
  • Goodwill may or may not be transferred if you buy a business, since it can come from physical features like location, or from personal factors, like the owner’s reputation or relationships with customers or suppliers
  • If a business is underperforming and has no goodwill, then using net asset valuation could be an accurate way to value it 

  • When you buy a business, you’re buying its assets and the right to all profits the business might generate
  • Capitalising future earnings is the most common method used to value small businesses
  • It considers the rate of return on investment (ROI) that you can expect to get from the business

How it works

  • Work out the average net profit of the business over the last three years using its profit-and-loss statements, adjusting profit for one-off expenses or other irregular items each year
  • Decide on the annual rate of return you’re looking for (e.g. 20 per cent)
  • There are no rules about the number you choose, except higher risk should give higher returns
  • Compare the business with other investment opportunities
  • You can also look at the rate of return that similar businesses in your industry achieve
  • Divide net profits by the rate of return to determine the value of the business, then multiply by 100


David is looking at buying a bakery business with average net profits of $100,000 per annum after adjustments. David wants an annual rate of return of 20 per cent. The capitalised earnings valuation is:

  • David will pay $500,000 now for a business he believes will earn $100,000 a year plus 20 per cent more profit each year into the future

  • Multiply the business’ earnings before interest and tax (EBIT) by your selected multiple
  • For example, you might value the business at twice its annual earnings – so a business with an EBIT of $200,000 might be valued at $400,000
  • The multiple you choose will depend on the industry and the growth potential of the business
  • A service-based business might be valued at as little as one year's earnings, while an established business with sustainable profits might sell for as much as six times earnings 

  • Whatever other valuation method you use, you should also look at prices for recent sales of similar businesses
  • Research what’s happening in the market you’re interested in
  • Speak to business brokers and gauge their feelings about the business’ value
  • A broker may know what similar operations are selling for and how the market is placed
  • Check business-for-sale listings in industry magazines, newspapers or websites
