How much of a cut does the publisher and steam take from a $20 purchase?
* Refunds and VAT 16% overall
* Steam cut 30% below $10,000,000 sales
* Publisher cut from net profit after recouperation is around 50%
So developer get around $5.88, but obviously for some countries it's can be better because there is no VAT or lower VAT, but price there would be like $5-15.
PS: And yeah from $5.88 you still owe some corporate tax.
