Job installation fee

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).

$\text{Job cost}=\text{Estimated items value}\times \text{System cost index}\times \text{Structure bonuses}$

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).

$\text{Estimated items value}=\sum _{\text{all materials}}\text{Material quantity}\times \text{Material adjusted price}$

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.

$\text{System cost index}=\sqrt{\frac{\text{Work hours done in system in past 28 days}}{\text{Work hours done in universe in past 28 days}}}$

You will also need to pay tax to the structure owner. The tax is based on the job cost so low system cost index will mean low taxes too.
