In today´s automotive industry new technologies are being used to create as environmentally friendly and crash proof cars as possible. These techniques do often have high investment costs and require advanced equipment. To determine if an investment is profitable different calculation methods are being used. When making investment decisions, researchers believe that it is favourable to use life cycle costing due to its consideration of all costs from purchase to scrapping. The purpose of this study is therefor to create an understanding of the costs that may arise during an investment's life cycle. The goal is then to create a calculation model that covers these costs and generate a reliable investment basis. The calculation model has mainly been developed based on previous research but also with inspiration from interviews and the case company's maintenance system. The calculation model has been created with several alternatives so that the user can compare these options and choose the alternative that means the least cost for the company. A sensitivity analysis can also be created using these alternatives. Maintenance costs has been a great focus when developing this calculation model due to researchers that believe there is a major problem in how traditional calculation models treat corrective maintenance. The calculation model has been tested at an automotive company that uses press hardening technology when manufacturing cars. This study has focused on the company´s press hardening furnaces because it´s the costliest part of the process. The results of this study showed that the press hardening furnaces were not profitable as the annual payment surplus is negative. But since the press hardening furnaces is the costliest, there should be other processes that compensate for this and that generate an annual payment surplus that is positive. A conclusion of this study is that the calculation model is more suitable for studying a whole process rather than part of a process. The case company is also recommended to further develop the calculation model to obtain more accurate values for mainly quality deficiency costs, raw material cost and revenues.
