If this is a theoretical thing, then if you have capital, drawings and a net asset figure (from our first equation thing) you don't need the net profit figure. Surely it would be the difference between capital - drawings = net profit that would equal net profit? (Its late, so I could very probably be wrong!)
Income Sales (minus VAT/excise duties) for net sales then minus cost of goods = Gross Margin
Gross Margin minus Variable costs minus Fixed Costs equals Profit before depreciation and tax.
Then take of your depreciation, calculate your tax, deduct that....net income after tax. Add back depreciation for your cash flow.
Well it's not a homework, but it is for a subject at Uni and I'm just trying to figure out how it works as I have never done this before.
But thanks anyway for your answers!
