Economic profit is calculated as:
Economic profit = Total Revenues – Total Cost
Total cost both includes explicit and implicit cost. In
this case, the explicit cost is $8,000 while the implicit cost is $64,000.
Explicit cost is a direct payment made to run the business while implicit cost
is the opportunity as accountant that is lost. Therefore,
Economic profit = $150,000 – ($8,000 + $64,000)
Economic profit = $78,000
