In accounting, total revenues less total expenses including income tax leads to Net Income After Tax (NIAT), so Dr Cousins has not considered all her costs.
However, there is an alternative solution as I don't know the full context of your question:
Pure Profit often means economic profit. Economic profit considers both explicit and implicit costs. Thus, Pure Profit is what remains after subtracting all conceivable costs (including implicit costs) from gross revenue.
Accounting Profit = Total Revenues - Explicit Costs
Economic Profit (also known as Pure Profit) = Accounting Profit - Implicit Costs
Note
- Explicit costs are regular business expenses.
- Implicit costs are what the business gave up in order to do something else (opportunity costs).
