As i wanted to understand ME on BPO¦s and doing so in a spreadsheat and as i have looked on previous threads i cant get the math to work. What i want to do is to use the level of the ME value and use it in conjuction with base/perfect build( PE lvl 5 presumed ) and get the mineral need.
Presuming the skill is PE 5 and ME at 75. Using the capital component blueprint for Capital Propulsion Engine.
Calculating mineral Tritanium: 452480, at base/perfect build with ME0( looked on in-game BPO from market )
Calculating mineral Tritanium: 426387, at base/perfect build with ME75( looked on my researched BPO from inventory )
As I can understand, ME0 is 10% and by researching ME, 10 will slowly decrease towards 0. With the formula (0.1/(1 + ME)) gives 0,13% waste factor. That would make, in my sense that is, ME75 is 9,87%( 10-0,13 ) less mineral needs compare to ME0. But by dividing perfect build/ME75( 426387 ) with perfect build/ME0( 452480) gives only a suggestion of 5,77% less mineral needs compare to ME0. Though that procentage does not add up compare to the original value at perfect build/ME0 since that gives 450989,5299 = 426387 * 1,0577. So.. i am simply, were is my calculations going wrong( since is soon midnight, i presume my math and brain is not fully functioning) Please, show me how to properly use ME level to calculate the correct value of mineral needs from a base of perfect build mineral needs from BPO¦s.

From what I have read, given a BPO with base 10% waste, the "quick" formula is the number of the largest resource divided by 5.5. For your example that would be around ME 87k. Most other resources will bottom out long before Tritanium.

ME 0: base * (1 + 0,10 / (0 + 1)) = 452480
ME 75: base * (1 + 0,10 / (75 + 1)) = 411186 not 426387.
Check the BPO again.

The equation for calculating minerals required for manufacturing is as follows.
MineralRequirement: Mineral quantity required to build the item given player skills and ME level of blueprint
Base: Mineral requirement for a perfect build, this is not the value given on the blueprint in game
PE: Production Efficiency skill, player skill 0 to 5
ME: Material Efficiency level, found on attributes tab of the blueprint
MineralRequirement = Base*(1+.05*PE+.1/(1+ME))
If you need to solve for 'Base' re-arrange your calculation as shown:
Base = MineralRequirement/(1+.05*PE+.1/(1+ME))
The value for 'Base' can be found on numerous websites if you don't care to calculate them yourself. This is my favorite site for 'Base' values.

MineralRequirement = Base*(1.25-.05*PE+.1/(1+ME))
If you need to solve for 'Base' re-arrange your calculation as shown:
Base = MineralRequirement/(1.25-.05*PE+.1/(1+ME))
But if "MineralRequirement" is based on "Base", how can i calculate "Base" based on that I need to know "MaterialRequirement" ? On the other hand, thanks for the correction on the "MineralRequirement" formula and website for "Base" values.

ingame and on the item database, the waste is automatically calculated so it contains the numbers you already have (i.e - waste is built in already).
What it doesn't have is the ME level formula reduced/added (for negative ME values which is a different formula too), which you have to do manually.
You could download either spreadsheet and see the formulas for themselves, it IS in two parts, the base materials and the waste factor.
There's also a thread for formulas in this section that contains the correct manufacturing formulas as the one on the wiki is slightly wrong but I can't change it as I have no idea how to do so.
Good luck, if you don't like my spreadsheet (excel 2007 preferred) feel free to use the formulas for your own design.

If you know the waste, it is simple.
10% waste: divide the material amount shown on a ME 0 BPO by 1,10 (see my post above, there is only 1 unknown, which is easy to solve for).

Tau is correct.
The minerals required shown on the blueprint already includes the waste attributed to ME.
