Income allocation

I just watched your taxes video!! So good. I have already estimated my tax payment but have been resisting putting the money in the savings account 😂.

I think i saw in another video you said we could expect a 50% profit.

Does that break down to:
40% taxes
10% expenses (tools, traffic & contractors?)
50% profit

I was thinking 30% profit, 30% expenses & 30% taxes.
