Calculating Materiality UK

Calculating materiality is one of the fundamental concepts in auditing. MyWorkpapers' materiality workpaper provides you with an automated, but highly flexible workpaper, ensuring that you can effectively apply your professional judgment whilst calculating materiality, but also retain the advantages of being an electronic system.

The following section will only instruct how to use the functionality of the B41 Materiality workpaper in MyWorkpapers and is not intended to instruct you on how to calculate materiality to be compliant with the International Auditing Standards.

To instruct you on how to use the B41 Materiality workpaper, we will break the completion of the workpaper into four distinct steps, being:

  1. Selecting the Benchmarks;

  2. Selecting the Basis for Determining Materiality;

  3. Calculating Overall Financial Statement Level Materiality; and

  4. Calculating Specific Materiality.

Before we begin with the specific details of the Materiality workpaper, please open B41 Materiality from the Working Paper Index.
