The top of the overhead tab shows a summary of all chosen data from this slide used in calculation of the total part cost in the model. The profit and general overhead can be allocated on three different bases. 
1. % Total Turnover
2. % In-House Value Added + Raw material
3. % In-House Value Added
Which base that is appropriate for calculations depends on what resources that are used in completion of the part. For instance if the purchased parts and outsourced processes, value that the supplier themselves have not created, are significant part of the total part cost; overhead and profits should not be based on the influence of this cost. If not any raw material is used then only in-house value added as inspection or assembly steps will be the base for overhead and profit costs. 
Example: A part which value to 70% consists of purchased parts, adding overhead and profit on the value of purchased parts then produced an infalted margin depending on value that was not added at the supplier. A solution to base overhead and profit on in-house value added + raw material instead reduced the price with 8% solely based on this factor.
Financial interest influences cost for investments made by the supplier and is generally quantified to the rate that banks make capital available.
Production overhead is a cost distributed per process hours described under “Production Overhead”.
The direct labour rate can be determined in three different ways, through financials, information or own estimation. The base for these calculations are showed later in this section.
The room cost rate can be determined in three different ways, through rent, investment or own estimation. The base for these calculations are showed later in this section.
In the automotive industry the general overhead should lie between 7 and 11% of the turnover, depending on volume of production, location of production, technical level of the product and size of the company. In general, net profit would be between 3 to 5% of sales price in industrial sectors such as automotive business.
