The objective of this study is to assess how managerial accounting influences decision-making processes within insurance companies. Utilizing a descriptive analytical method, the researchers focused on a study population that included all employees from insurance companies, amounting to 2826 individuals. Data collection was carried out through a questionnaire, resulting in 313 completed responses for analysis, which corresponds to roughly 92% of the distributed questionnaires and is considered adequate for the study’s aims. The findings revealed that managerial accounting practices in insurance companies received a high rating, as did the decision-making process. Furthermore, the results indicated a positive relationship between the elements of managerial accounting (such as activity-based costing and target costing) and the aspects of decision-making (including decision speed and decision quality) within these companies. In light of these outcomes, the study suggests that insurance companies should fully embrace the principles of managerial accounting due to its advantages in improving the decision-making process.
