Total job cost

Raw materials are not the only cost of production. The act of installing the manufacturing job costs too. The job installation fee is a factor which cannot be ignored in choosing where to base your manufacturing operation is the installation cost of industry jobs. This cost is dynamic, so if a large number of other manufacturers join you in the system, it may save you money to move elsewhere (weighed against the cost in time and effort of moving all your materials to a new system).

[math] \displaystyle \text{Total job cost} = {\color{green}\text{Estimated item value} } \times ( ( {\color{blue}\text{System cost index} } \times \text{Structure bonuses} ) + \text {Facility tax} + \text{SCC surcharge} + \text{Alpha clone tax} )[/math]

The estimated items value approximately the cost estimation of the materials. The exact values can be calculated by multiplying the number of items with the adjusted prices of the items (found in ESI /markets/prices/ endpoint).

[math] \displaystyle {\color{green}\text{Estimated item value} } = \sum_{\text{all materials}} ( \text{Material quantity} \times \text{Material adjusted price} ) [/math]

The system cost index is calculated from the amount of production job hours done in system and the amount of production job hours done in universe.

[math] \displaystyle {\color{blue}\text{System cost index} } = \sqrt{ \frac{ \text{Work hours done in system in past 28 days} }{ \text{Work hours done in universe in past 28 days} } } [/math]

You will also need to pay taxes. The taxes are based on the Estimated item value. The tax is composed of the following elements:

Facility tax 

Fixed at 0.25% for NPC stations. Set by the owner for player structures.

SCC surcharge 

Fixed at 0.25%

Alpha clone tax 

Only applicable to Alpha clones, set to 0.25%

The maximum tax that can be set for industry services will be capped at 10%.
