AASB 13 Fair Value Measurement: A Plain-English Summary

What AASB 13 says, how the three levels of inputs work and what a valuation for financial reporting needs to show.

By Monita Asset Management Updated 31 October 2026 4 min read

Quick answer

AASB 13 sets out how fair value is measured in Australian financial reporting. Fair value is the price that would be received to sell an asset in an orderly transaction between market participants at the measurement date. Inputs are ranked in three levels, from quoted prices to unobservable data, and valuers use market, cost or income approaches.

AASB 13 Fair Value Measurement, often written AASB13, is the accounting standard that explains how to measure fair value once another standard says fair value is required or allowed. It is the Australian version of IFRS 13. This guide is a plain-English summary, and it explains where a valuation for financial reporting fits.

We are certified registered valuers, not accountants or auditors, so we stick to what the standard asks of the valuation. Your finance team and auditor decide the accounting policy. Our property valuers and plant and equipment valuers prepare values that follow the standard.

What AASB 13 does and does not do

AASB 13 defines fair value, sets out one framework for measuring it and lists what has to be disclosed. It does not decide which assets are carried at fair value. That comes from other standards. For example, an entity that uses the revaluation model in AASB 116 for property, plant and equipment, or the fair value model in AASB 140 for investment property, measures fair value using AASB 13.

The definition of fair value

Fair value is the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. It is an exit price. It is based on the market, not on what the current owner intends to do with the asset.

For non-financial assets such as land, buildings and equipment, the standard asks the valuer to consider the highest and best use: the use that a market participant would put the asset to that is physically possible, legally permissible and financially feasible.

The three-level hierarchy of inputs

The inputs used in a valuation are ranked by how observable they are. The higher the level, the more judgement and disclosure.

LevelWhat the inputs areExample
Level 1Quoted prices in active markets for identical assetsShares listed on an exchange
Level 2Other inputs that can be observed, directly or indirectlySales of similar properties, or quoted prices for similar equipment
Level 3Inputs that cannot be observed and rest on assumptionsA specialised plant item with no comparable sales, valued from cost

Many property, plant and equipment valuations sit in Level 2 or Level 3. The level is decided by the least observable input that matters to the result.

The valuation approaches

The standard describes three approaches. A valuer uses one or a combination, depending on the asset and the information available:

  • Market approach: uses prices from sales of identical or comparable assets
  • Cost approach: the cost to replace the asset with an equivalent one, adjusted for age, wear and obsolescence
  • Income approach: converts expected future income or cash flows into a present value

What an auditor looks for in the report

Your auditor decides what evidence is enough, so speak to them early. In general, a good report shows:

  • The measurement date, the asset and the basis of value (fair value under AASB 13)
  • The approach used and why it suits the asset
  • The key inputs and assumptions, and where they came from
  • The level of the hierarchy, and the reasons for it
  • Consistency with earlier years, so a change in value can be explained

Mistakes to avoid

Common mistakes:

  • Using market value and fair value as if they were the same. They are close, but the standard has its own definition and disclosure rules.
  • Ignoring highest and best use. Land and buildings are valued for the use a market participant would adopt, not only the current use.
  • Leaving the valuation until the audit. Inputs and evidence are easier to gather early.
  • Changing the approach without a reason. If the method changes from year to year, the movement in value is hard to explain.

FAQ

Questions owners ask

What is AASB 13?

AASB 13 Fair Value Measurement is the Australian accounting standard that defines fair value, sets out how it is measured and requires disclosures about fair value measurements. It applies where another standard requires or permits fair value.

Is AASB 13 the same as IFRS 13?

AASB 13 incorporates IFRS 13 as issued by the International Accounting Standards Board, so for-profit entities that comply with AASB 13 also comply with IFRS 13.

What are the three levels in AASB 13?

Level 1 is quoted prices in active markets for identical assets, Level 2 is other observable inputs, and Level 3 is unobservable inputs. Level 3 needs more judgement and more disclosure.

Which valuation approaches does AASB 13 allow?

The market approach, the cost approach and the income approach. A valuer uses one or a combination, depending on the asset and the information available.

Do I need an independent valuer for AASB 13?

Not always. Entities decide how to measure fair value, and an independent valuation is commonly used where the assets are significant or the inputs need expertise. Your auditor can tell you what evidence they expect.

How often do assets need to be revalued?

It depends on your accounting policy and how much values move. Your accountant or auditor can advise how often revaluation is needed.
