Sure but as Runa said you can attempt to place buy/sell orders and the game will show you the values of tax and brokers fees before actually placing them.
I want to sell an ‘Adaptive Invulnerability Field I’ so I check out the market:
Highest Buy Order: 56,001 ISK
Lowest Sell Order (in station): 127,899 ISK
That means there’s a person in this station asking to buy this module for 56,001 ISK and there’s a person willing to part with this module for 127,899 ISK.
If I want to sell, I have two choices:
Sell it immediately for 56,001 ISK
- Pay 0% to broker for an immediate sale, and pay 2% in tax (-1,120 ISK) to make 54,881 ISK which is deposited in my wallet immediately.
Place a sell order for 127,898.99 ISK (undercutting the lowest sell by 0.01 ISK)
- Pay 2.62% (due to skills) to broker (-3,347 ISK) and 2% in tax (-2,558 ISK) to make 121,994 ISK (once the item sells!) I have to wait for my item to sell on the market and hope I’m not undercut.
Buying works the same, just in reverse! An immediate buy doesn’t pay broker’s fee but placing a buy order and waiting to have it filled will have a broker’s fee.
