Installing research jobs is not free. Installing a ME or TE job will have the following cost:

::'' Job cost = Process Time Value × System cost index × Structure bonus ~~× Facility tax~~'',

::'' Job cost = Process Time Value × System cost index × Structure bonus'',

where Process Time Value is a number derived from the material cost of producing the item, blueprint rank and blueprint research level (ME and TE handled separately) and the system cost index is a number derived from the ammount of work done in that system.

Line 202:

The system cost idex is calculated as

:~~:'' System cost index = sqrt( Work hours done in system in past 28 days / Work hours done in universe in past 28 days ) ''~~

[[file:Formula_system_cost_index.png]]

~~(Work hours tracked separately for ME researc, TE research, copying, manufacturing and reactions)~~.

The Process Time Value for researching to leven ''n'' is calculated as

::'' ~~sum( number of materials × adjusted price ) × (0.02 / 105) × ( Base~~ durationn ~~- Base~~ duration~~~~n~~-1<~~/~~sub>)~~''

[[File:Formula process time value.png]]

where the ''base durationn'' is the job duration of researching a rank 1 blueprint to level ''n''. The sum term is usually very close to the price estimation of the raw materials of the blueprint but the exact value can only be found from ESI ''/markets/prices/'' endpoint.

You will additionally need to pay the facility tax which is

:: ''Facility tax = Job cost × Facility tax%''
