It's just interesting to collect some statistics on how much, on average, a studio takes into its pocket, and what part goes to pay for the work of specialists.

Answer 1

Do not forget about taxes and various expenses.
Example, the cost of the project is 500,000 rubles. The cost of the work of a designer, layout designer and programmer for the project is 150,000 rubles. Rent, taxes, etc. minus 150,000 rubles. Minus your X salary and there is income.
