I’m not sure if I’m posting this in the right place.

If it does need to be moved, I’ll be happy to do this, but I had to start somewhere and this seemed like the logical place.

So here goes.

First, I should explain that I have a learning disability, namely Dyscalculia, which means that I struggle to get my head around numbers *(but you still play Eve Online?! What can I say? I kinda love spaceships …)*.

The first bit of my question is about how to calculate the tax and associated trading costs involved in selling stuff on the market *(and, somewhat predictably, my brain is currently spinning like a neutron star)*.

I did find a helpful page on Trading on the brilliant Eve University website which gives the following equation for NPC broker fees:

Broker’s fee 5%, -0.3% X Broker relations level, -0.03% X Faction standing −0.02% X Corporation standing

With no skills or standing the broker’s fee is 5%. With broker relations V, the broker’s fee is reduced to 3.5%. With 10 faction and corp (i.e. perfect) standing the fee is further reduced to 3%.

I have L5 Broker Relations and my standing with the station that I’m in is 2.0, which is part of the Caldari State with whom my standing is 3.2.

Based on all of this I think the equation for me becomes:

**3.5% -0.096, -0.04 = 3.364%**

To work out the brokerage fee on any given sale, and allow for it in the price, I think what I need to do is take the value of what I’m selling and what I want to end up with in my metaphorical pocket *(say 100 ISK)* and apply the following sum:

**100 ISK ÷ 0.9636 = 103.77 ISK** *(which is the sale price inc. broker fee)*

The Eve University page then says …

When an item is sold on the market the seller will also pay sales tax. The base transaction tax is 5% and is reduced by 11% per level in Accounting (2.25% at max skills).

Sales tax % = 5% −0.55% X Accounting level

I have L5 Accounting so I think the sum is:

**103.77 ISK ÷ 0.9775 = 106.15 ISK**

Does all this make sense?

I had some help from my partner *(who’s both much better at maths than me, and highly tolerant of my Eve Online obsession too)* while I was writing this but I wanted to ask the forum hive mind just to double-check theat I haven’t ade any glaringly obvious errors, if that’s okay.

The second bit of my question is about contracts.

I have a Miasmos BPO which is fully researched. I have made some BPCs from this that I want to sell via contracts.

I checked the going price on the contracts window and for a 10 run Miasmos BPC the average price was 345,856 ISK. Based on this I’m assuming that the price for a one run BPC should be 34,585 ISK, so I set up a contract for that.

aI’m a bit confused about the costs though.

To create a copy of the BPO, costs 1,645 ISK *(and I have maxed out industry skills)*.

On the contact info there is a brokers fee of 23,500 ISK and also a sales tax of 10,000 ISK, totalling to 33,500 in fees. Unless I’m reading it all wrong, that basically I’ll make 1,085 ISK from the sale? *(I’m assuming that I get the deposit of 100,00 ISK back upon sale?)* Which would suggest that I’ll make a loss of 555 ISK.

How do people make money on selling BPCs? Is it a matter of finding a station where duplication is cheaper? *(1,645 ISK does seem pretty cheap to me)* or am I doing something wrong? Should I be making only 10 run BPCs *(this’d cost me 16,447 ISK to create)* to up the selling price?

All help and advice, on either of these two issues, will be gratefully received, thanks.
