*Illustration:
•Suppose you are earning $22,000 a year as a sales representative for a T-shirt manufacturer.
•And you invest $20,000 of savings that have been earning you $1000 per year.
•But, at some point you decide to open a retail store of your own to sell T-shirts.
•And you decide that your new firm will occupy a small store that you own and have been renting out for $5,000 per year.
•You hire one clerk to help you in the store, paying her $18,000 annually.
•Additional Information: Cost of T-Shirts --------------------------- $40,000
Utilities Expenses ------------------------ $ 5,000
oYour entrepreneurial talent is worth $5,000 annually in other business endeavors of similar scope.
A year after you open the store, you total up your accounts and find the following:
Total sales revenue ------------ $120,000 Cost of T-shirts ---------- $40,000
Clerk’s salary ------------- 18,000
Utilities -------------------- 5,000
Total (explicit) costs --------------- 63,000Accounting profit ----------------------- 57,000
Accounting profit ----------------------- $57,000 Forgone interest ------------ $1,000
Forgone rent --------------- 5,000
Forgone wages -------------- 22,000
Forgone entrepreneurial income ---- 5,000
Total implicit costs --------------------------- 33,000 Economic profit -------------------------------- 24,000
Considering the implicit costs:
*Accounting Profit vs. Economic ProfitAccounting profit
- total revenue minus total explicit costs
Economic profit- total revenue minus economic costs or
the total costs (including explicit and implicit costs)
“Accounting profit ignores implicit costs, so it’s higher than economic profit.”
