Opportunity cost is the fortified benefits when a choice is made. It is the sacrificed option from a variety of possible choices. The value of opportunity cost is expressed as the cost of the next best alternative.
According to the economist, Joe made a loss because his opportunity cost would have yielded a better return. In evaluating the viability of a project, economists always consider the returns from the next best alternative. Joe would have made a profit if the returns from the sales of gold were higher than the 3 percent from a certificate of deposit.
