Hello guys.
I'm trying to find out how this price for installing manufacturing jobs works, and I'm kinda loss.
From what I read on web and saw from ingame, it basicly works : Base item cost * system multiplier
But how is that base item cost calculated I was not able to find out.
It looks like it takes the price of input materials, but how is it getting the price of the minerals for example? Is it region wide? EVE wide? Jita price?
Was there any dev blog to this matter?
Thank you |

There's a crest endpoint to get the prices used for this.
https://public-crest.eveonline.com/market/prices/
You want the adjusted figure.
The base cost is based off the ME 0 materials.

Just to add to this since it seems to be a question that comes up every few weeks, you multiply the ME 0 material quantity by the adjusted price from that end point above and add them all up. So using 1MN Afterburner I as an example:
Mat -> Quant * Adj Price = Sub Job Cost
Trit -> 708 * 4.06 = 2,874.48
Pyerite -> 643 * 8.57 = 5,510.51
Mex -> 1 * 32.94 = 32.94
Nocx -> 1 * 482.5 = 482.50
Total = 8,900.43
Then you multiply that by the system modifier and total runs to get the Job Fee. The Facility Usage is the Job fee * Facility Tax (10% for stations, 0% for POS and whatever it is set to at an Outpost) and then then Total usage is the Job Fee + the Facility Usage.
This is a good resource: http://api.eve-industry.org/
Qoi's indy sheet is also very handy for this sort of thing: http://eve-industry.org/export/IndustryFormulas.pdf

How is the "Adjusted Price" for resources/inputs derived in the first place? Now that's a mystery. 
Smells like price-fixing of some kind.

Yes, it is. By CCP, to stop price manipulation.

It is a reasonable measure - otherwise the costs of the spiking mineral prices along with the increased job installation costs on top of that could render new production unprofitable.
The colleagues that I am in contact with said that most T1 has recovered since the Apr 28 MegaZyd changes.

There is something I don't understand about total job cost and I was wondering if any of you could help me.
I'm trying to build something in a POS equipment assembly array.
When I put the mouse cursor over "total job cost" here is what I see :
Base item cost : 868 054 ISK
System cost index : 3.80 %
Total job cost : 32 967 ISK
First weird thing : if i use adjusted prices from CREST, the base item cost I get for the item is 868 055.42 ISK.
Even rounded you can't possibly find 868 054.
Second weird thing : To calculate the total job cost the formula should be : 868 054 * 0,038
But the result is 32 986.052 and not 32 967 as the game says.
Even if I use my own base item price calculated from CREST, I don't find the 32 967 ISK from the game.
My question is what did I do wrong? |

you don't use the base cost of the item. you use the base cost of the materials, at ME 0
(thus allowing for super caps and titans to be built  )

CCP hasn't published the process behind it and AFAIK no one has reverse engineered it so far. "averagePrice" seems to reflect the eve-wide average price for that traded item type.
I have a year worth of these values in a DB. Just glancing at it you can see that both values get updated once per week and that averagePrice is greater than adjustedPrice 5 out of 6 times. More research required...

Yes, I used the material amount from ME0 Blueprint and adjusted prices from CREST.
I used Fuzzwork blueprint calculator and it returns the same base item price, which is different from the one the game gives.
I'm wondering why.
Also, I thought the formula for job cost was : Base Item price * system cost index * facility tax,
which should become base item price * system cost index
in a POS as there is no facility tax.
If I use the formula with the values the Game gives me : 868 054 and 3.80 %, I get a job price of 32 986.052 ISK (868 054 * 0.038).
But the game says the job price is 32 967 ISK.
So it's either my formula is wrong either the game has a weird way of calculating percentages. |

Your off by 19 isk, is this your issue? If so, it's probably due to the time lag between the system index in game vs the crest update, which can change quickly during the day.

It's probably that.
I update the indexes and prices once per hour, but the update cycles won't precisely match with what's in game. I figured it was close enough.
