System cost index and facility tax

Hello

Facility tax now works as percent of system cost index which is super confusing because it leads to situations where manufacturing in station with 5% system cost index and 50% tax end up being cheaper than in station with 10% system cost index and no tax.

I think it would be good idea to make tax as % base item value instead of system cost index so total cost will be

ManufacturingCost=ItemBaseValue*(SystemCostIndex+FacilityTax)

instead of current

ManufacturingCost=ItemBaseValue*(SystemCostIndex+SystemCostIndex*FacilityTax)

Please note that manufacturing cost bonus from engineering complex is purposefully omitted this time for sake of simplicity but might also need some work.

So, no one thinks it's a good idea?

Welcome to the world of business. Figuring how to pay the least in taxes while making the things you are supposed to make is a major portion of running a real life manufacturing process why should the game be any different?

Not liking your idea for another reason so let's assign some arbitrary numbers to this and run the math.
Item Base Value = 100
System Cost index = 10
Facility tax 5% - converted to a decimal number to use in math formula that is actually 0.05.

Currently we use ManufacturingCost=ItemBaseValue*(SystemCostIndex+SystemCostIndex*FacilityTax)
100 * ( ( 10 + 10 ) * 0.05 ) = 100

With your formula ManufacturingCost=ItemBaseValue*(SystemCostIndex+FacilityTax)
100 * ( 10 + 0.05 ) = 1,005

One has to wonder, did you actually test your formula with a spread sheet or calculator before you posted it?
Did you really intended to make manufacturing stuff more than 10 time as expensive?

So you're saying they should drastically increase the cost of manufacturing in NPC stations just because you find the current formula mildly confusing?

What's up next, suggest they remove stacking penalties, turret tracking and a bunch of other stuff that can't be figured out with the four basic arithmetic operations? Maybe they should make EVE in 2D, like a side-scroller with ships.

You are missing the point. Tax can be adjusted so the total cost remains the same.

in your example should be

100 * ( 10 + 10 * 0.05 ) = 100 * ( (10 + 0.5 )=1050
instead of
100 * ( ( 10 + 10 ) * 0.05 ) = 100

so new formula would give lower cost

also system tax is capped at 10%=0,1

It's not about me because I understand how it is calculated. It's for people who are looking for place to manufacture stuff and go where taxes are lower and end up paying more because they don't know about it.
There is also second reason. As for now station owner income varies greatly with changing system cost index. In my proposal it would be constant and independent.

This may be the formula you intended to post, but this is not what you posted.e


ManufacturingCost=ItemBaseValue*(SystemCostIndex+SystemCostIndex*FacilityTax)
Unknown = 100 *( 10 + 10 * 0.05 )

Removing all the extra spaces we get
Unknown = 100 * ( 10 + 10 * 0.05)

Standard math procedures dictate calculating inside parenthesis first so this one actually solves as if it was written this way.
(10 + 10 * 0.05) * 100 = unknown
And based on that and testing it on more than a dozen calculators I have laying around the answer comes up as 100 on all of them.
10 + 10 ( = 20) * 0.05 (= 1) * 100 = 100.

Dude wat? Do you even math? FYI 10 + 10 * 0.05 you have to multiply first and then add

Alternatively, could be changed what is displayed under tax in facilities section, so it will inform about total tax instead of system index and station tax separately, without any information how is one related to another.
