Defining Profit Lesson 4.52, 4.53

Understanding Profit (52) Profit = Total Revenue – Total Costs Explicit vs Implicit Costs – Explicit costs require payment of money – Implicit Costs are benefits or value lost Opportunity Costs Accounting Profit vs Economic Profit – Accounting Profit = Total Revenue – (Explicit Costs + Depreciation) – Economic Profit = Total Revenue – (Explicit + Implicit Costs) Normal Profit – When economic profit = 0, use of resources is maximized
