The artist gets paid 80% of the profit, while the founder gets paid the commmision of 20% plus 21% of VAT (on the commisson).
Here is an example to illustrate how this works:
Let’s take a product of $100. 20% commission = $20
So $100 – 20% = $80. Which means that vendors get paid $80.
The 21% VAT is calulated on the $20 (value-added tax that we return to the governement).
So $20 + 21% = $24.2
Artists earnings equal to $75.8.
Therefore this does not mean that commission turns out to be 41%. Rather the commission is only 20% on which we add the 21% VAT on top.
