REVENUE, COSTS & PROFIT
Profit
Total (accounting) profit = TR minus Total explicit costs
Normal profit = Best return that a firm’s resources could earn
elsewhere and is part of the cost of production.
Economic profit = Total revenue minus Total cost (Explicit and implicit
cost including normal profit)
