The correct evaluation of the logistical costs of a company allows better management of these costs and a more accurate decision making process. This work addresses the obtainment of logistical costs through the traditional method of cost assignment, points out problems that make it unsuitable for this task, and suggests the use of contemporary tools. Despite considering the importance of the total logistical costs, this work develops the analysis only for the costs of shipping, since these are the most relevant to the case under approach. To solve the inadequacies of the traditional method of cost assignment, it is suggested the Activity-Based Costing method (ABC). This method allocates the cost of resources in accordance with the activities over which they were used and brings forth good results in the managerial evaluation of logistical costs. In addition to this method, it is suggested the use of Total Cost of Ownership (TCO) for hiring ships. This tool evaluates the cost of obtaining and using a good or service, including other variables besides price. The results of this work are favourable to the use of the tools, but there is the need of extensive internal work in its field of application to have it implemented.
