The Audit Risk Model outlines the components of audit risk and provides a formula to calculate audit risk. The components are inherent risk, control risk, and detection risk. The Audit Risk Model formula is: Audit Risk = Inherent Risk x Control Risk x Detection Risk or Audit Risk = Risk of Material Misstatement x Detection Risk. The model is used to determine audit risk and risk of material misstatement. Limitations include that the desired audit risk level may not be achieved and it does not consider potential auditor error or nonsampling risk.
