Don’t forget taxes. I would about half his gross revenue to get a realistic handle on the kind of money he is making. Three million Euro so far seems like a realistic estimate to me.

Ah, the taxman, how could I forget thee! It'll be around ~51.3% in Sweden incl. the VAT.

I'm not sure how Notch has his affairs organized, but the corporate tax rate over there is only 26%.

I remembered to check this because all European countries have lower corporate tax rates than America.

Corporate tax rates are way lower but personal income tax rates are significantly higher. So if he pays all of that money as salary to himself, that 50% number is quite realistic.

I'm assuming he will keep at least part of his money in a corporation to develop his game.
