Guild Wars 2

Selling items currently is not profitable for any player who understand a bit of economy.

Currently selling items you have to pay a listing fee which in general isn’t much, but after several attempts I find that the listing fee that deducts from your trade profit is double the amount.
I have tried various different items and various different pricing and deducted the problem to be in that one single variable.

example.

250 copper ore selling 20 each
profit is 50 silver
listing fee for the amount is 2 silver 50 bronze

total profit is supposed to be 47 silver and 50 bronze

i get 45 silver

in total in this manner have lost approximately 30-40 silver just trying to find out what could be the cause of the issue

on the other side there is a good thing to it where a lot of players currently are trying to buy items to resell them for fast money (buying 250 copper for 18 = 45 silver then sell for 20 should get 47.50 yet gets 45 so no gains or losses), but then it effects those who try to earn in a fair way by mining ores and chopping down trees.

Edit:

After reading a few more pages I found that apparently the listing fee is 5% of the total sale which will not be refunded if canceled (fair enough) and that not only there is a 10% deduction to the amount gained through the sale.

using simple math this still does not add up properly. anyone have any ideas of what could be the cause of the problem??
