| === System Cost Index === | | === System Cost Index === |
| When you install an industrial job - manufacturing or research - you need to pay an installation cost. This installation cost is calculated per system, and is dynamic, being based on how many other people have been using that system for manufacturing over the last 28 days (measured in job-hours, not # of jobs or # of people).
| | A cost 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). |
|

|
| The system cost index is calculated by the number of system-job-hours, divided by total-universe-job-hours, and then square rooted for better numbers. This value (measured as a percentage, generally in the 0.01% to 5% range) is then multipled by the job base value, which is:
| | See the [[Industry_Overview#System_Cost_Index|System Cost Index]] section on the Industry Overview page to find out how system cost index is calculated. |
| * Manufacturing: actual estimated value of the input materials
| |
| * Research / Copying: 2% of the estimated value of the input materials required for manufacturing from the BPO
| |
| * Invention / Reverse Engineering: 2% of the estimated value of the input materials required for manufacturing from the BPC(s) you are hoping to get out of the job, averaged across multiple BPCs if there is more than one potential outcome.

| [[File:System cost index.png|right]] NPC stations have a 10% tax on top of this final value. | |

| {{example|1=For example, if we build the [[Rifter]] from the earlier screenshot, it has an estimated input value of 470,000 ISK. If my hi-sec manufacturing system had 0.085% of the universe manufacturing activity, then the installation cost would be 470,000 x 0.085% x 10% tax = 439 ISK installation cost.}}
| |
| {{example|1=If instead we were [[Invention|inventing]] from a [[Rifter]] BPC, we would be hoping for either a Jaguar or Wolf BPC. Looking at the required materials for those T2 BPCs, gives an estimated input of roughly 20m ISK for manufacturing a Wolf or Jaguar. If my hi-sec inventing system had 0.13% of the universe manufacturing activity, then the installation cost would be 20,000,000 x 2% x 0.13% x 10% tax = 5,720 ISK installation cost.}}

| You can find out the system cost index for nearby systems by using the Facilities tab of the Industry window. Each activity at a certain facility will have a red bar at the bottom of the icon, indicating relatively how expensive it is to install a job there. Mouseover will show you what can be built there, and a more detailed indication of the system cost index (see image to right).
| |
| | |
| Choosing a system with a low system cost index is important, but it must be weighed against the possible impact of having to move your materials and/or products to market. Picking a very low cost system at some distance from the market hubs may seem attractive at first glance, but your transport costs for that further distance will be increased instead.
