Business and Share Valuation: Methods, When You Need One and What Affects Value

The three valuation methods, what a share valuation involves and the situations that call for an independent business valuation.

By Monita Asset Management Updated 31 October 2026 5 min read

Quick answer

A business valuation is an independent opinion of what a business, or an interest in it such as shares, is worth at a date and for a purpose. Valuers use income, market or asset-based approaches, chosen to suit the business, and the report explains the method, the inputs and the assumptions behind the figure.

A business valuation sets out what a business is worth, and a share valuation does the same for an interest in it, such as shares in a private company or a partnership share. This guide explains the methods, when you need one and what affects the figure, and it links to our business valuation service.

We are certified registered valuers, not tax advisers or lawyers. We value the business and explain the reasoning, and your accountant or solicitor advises on what it means for the tax or the dispute. Where the purpose is an acquisition, see our guide to purchase price allocation.

What can be valued?

A valuer can value the whole business or a part of it:

  • A going concern: the business as a trading operation
  • Shares and equity interests: shares in a private or unlisted company, shareholder and partnership interests
  • Goodwill and intangibles: brands, customer relationships and intellectual property
  • The assets of the business: property, plant and equipment, which may be valued separately by a plant and equipment valuer or property valuer

The three valuation methods

The right method depends on the business and the purpose. Valuers follow the International Valuation Standards and, in Australia, APES 225 Valuation Services, and the report explains which method was used and why.

MethodHow it worksOften suits
Income approachValues the business on the earnings or cash flows it is expected to generate, for example by capitalising maintainable earnings or discounting future cash flowsTrading businesses with a profit history
Market approachCompares the business with similar businesses or transactions, using multiples drawn from market evidenceWhere reliable comparable sales exist
Asset-based approachValues the net assets of the business, adjusted to market valueAsset-heavy businesses, holding companies and wind-downs

What is different about a share valuation?

A share in a private company is not simply a slice of the business. Its value depends on what it gives the holder: whether it carries control, what rights it has under the constitution or shareholders' agreement, how the company is run and how easily the interest can be sold. These points can raise or lower the value of a minority or a controlling interest compared with a simple percentage of the whole business.

When do you need an independent valuation?

Business and share valuations are most often needed to:

  • Sell, buy or merge a business and agree a fair price
  • Set a buy-sell price between partners or shareholders, or settle a shareholder dispute
  • Divide assets in a family law property settlement
  • Support tax planning, succession and estate matters
  • Allocate the price after an acquisition, or report fair value in the accounts
  • Support a loan, a restructure or an insolvency process

Need a business or share valuation?

Tell us about the business, the purpose and the date and we will confirm the scope and the fee before any work begins.

What affects the value?

The value depends mainly on:

  • The profit the business can reliably keep earning (maintainable earnings)
  • How dependent the business is on its owner
  • Its assets and its debts
  • The strength of its customers and contracts
  • The risks in its industry and the state of the market

What a valuer needs from you

The list depends on the job, and we confirm it at the free consultation. In general:

  • Several years of financial statements, management accounts and tax returns
  • Details of key contracts, leases and customers
  • A list of assets and liabilities
  • The constitution or shareholders' agreement, for a share valuation
  • The purpose of the valuation and the date you need the value for

Mistakes to avoid

Common mistakes:

  • Relying on a rule of thumb. Industry multiples are a starting point, not a valuation.
  • Ignoring owner dependence. A business that relies on one person is usually worth less than one that does not.
  • Using one year's profit. Valuers look at a pattern, and adjust for one-off items.
  • Valuing a minority share as a slice of the whole. The rights and the ability to sell the interest affect its value.
Key terms explained
Going concern
A business that is expected to keep trading, as opposed to one that is being wound up.
Maintainable earnings
The level of profit a business can reasonably be expected to keep earning, after adjusting for one-off items.
Goodwill
The value of a business over and above its identifiable assets, such as its reputation and customer base.
Minority interest
A shareholding that does not control the company. It can be worth less or more than its share of the whole, depending on its rights and how easily it can be sold.
APES 225
The professional standard that sets out requirements for members of Australian accounting bodies who provide valuation services.

FAQ

Questions owners ask

What is a share valuation?

A share valuation is an independent opinion of what shares or another interest in a business are worth at a date and for a purpose. It looks at the value of the business and at what the interest gives the holder, such as control, rights and how easily it can be sold.

What is the difference between a business valuation and a business appraisal?

In everyday use the two terms mean the same thing: an independent opinion of what a business is worth. A formal written valuation sets out the method, assumptions and reasoning so it can be relied on by buyers, lenders, advisers and courts.

Which valuation method is used?

Income, market and asset-based approaches, applied as appropriate to the business and the purpose, in line with APES 225 and the International Valuation Standards.

Can the report be used in family law or court matters?

Our expert reports are prepared to the standards required for use as expert evidence in Australian courts and tribunals. Whether a report is suitable for a particular matter is confirmed at the free consultation.

What information do you need?

Typically several years of financial statements, management accounts and tax returns, details of key contracts, assets and liabilities, and the purpose and date of the valuation.

How much does a business valuation cost?

The fee depends on the size and complexity of the business, the purpose of the report and how complete the records are. Every initial consultation and quote is free, and you receive a firm fee estimate before any work begins.
