Hi, I am a bit stuck as to how this is calculated (I am running a spreadsheet for PI and its great :P)

Import fee calculation is: (Import fee = Base cost * tax rate * 0.5) * number of units to import

Tax rate is 5% == 0.05

I have 2 P3s (540 m3 each) and 1 P2 (3600 m3) to import and basically after the import tax you multiply it by how many units of that p3/p2 there is to import

So ((70,000 * 0.05 * 0.5) * 540) + ((70,000 * 0.05 * 0.5) * 540) + ((9,000 * 0.05 * 0.5) * 3600) = 2,700,000 ISK import tax but I am only charged 1,935,000 ISK!

Can anyone help me as to what I am missing?

sm; dr

Wait you are complaining that you pay less than expected? :p

And import taxes are always half of the export taxes, that may be the issue?

Yea, I need my spreadsheets to be accurate :P

Also, the formula is for import taxes so it takes into account the half of export tax stuff...

Is each unit of product 1 m3? If import/export is based on units rather than volume, this is probably your difference.

Looks to me that P2s (Coolant, Mech Parts, etc) are 1.5m3 each and P3s (Robotics, etc) are 6 m3 each.

I've definitely made sure that I used units instead of volume for the income tax calculation

OK, because here it looks like you're using volume rather than units. I don't remember what rate the tax is charged at, to be honest.

Also, is there any way to check to see if the tax rate is actually something like 4.75% and being rounded to a whole number in the display? I'm not that familiar with POCO mechanics.

ETA: As far as I can tell, I don't think those numbers are accurate. You might want to double check them.

540 is the number of industrial explosives and ukomi superconductors needed and 3600 is the number of reactive metals needed for one PI installation which has 10 production facilities which is going to run for 9 cycles. To get the volume of, say, industrial explosive you would times the quantity by the volume per unit which is 6 m3 thus 540 * 6m3 = 3240 m3

Also a tax change to 0.045 would not affect the import tax that much.

OK, in your OP you indicated 540m3 and 3600m3, which was the cause of my initial confusion. Thanks for listing the actual products. That's where your problem lies.

Reactive Metals are a P1 product. Industial Explosives and Ukomi Superconductors are P3. So...

((70,000*0.05*0.5)*540)+((70,000*0.05*0.5)*540)+((500*0.05*0.5)*3600) = 1,935,000 ISK

Thank you very much :) Could have sworn that reactive metals was p2 but I forgot that raw materials start at p0 not p1!!!!! Time to play Eve: Spreadsheets in Spaccccccccccccce!
