The sunk cost fallacy is the improper mindset a company or individual may have when working through a decision. This fallacy is based on the premise that committing to the current plan is justified because resources have already been committed. This mistake may result in improper long-term strategic planning decisions based on short-term committed costs.
When making business decisions, organizations should only consider relevant costs, which include future costs—such as decisions about inventory purchase costs or product pricing—that still need to be incurred. The relevant costs are contrasted with the potential revenue of one choice compared to another. Sunk costs are excluded from future business decisions because the cost will remain the same regardless of the outcome of a decision. When making business decisions, organizations should only consider relevant costs, which include the future costs that still needed to be incurred.

Sunk costs are excluded from future business decisions because they will remain the same regardless of the outcome of a decision.
To make an informed decision, a business only considers the costs and revenue that will change as a result of the decision at hand. A sunk cost is a cost that an entity has incurred, and which it can no longer recover. Sunk costs should not be considered when making the decision to continue investing in an ongoing project, since these costs cannot be recovered. However, many managers continue investing in projects because of the sheer size of the amounts already invested in prior periods. They do not want to “lose the investment” by curtailing a project that is proving to not be profitable, so they continue pouring more cash into it. Rationally, they should consider earlier investments to be sunk costs, and therefore exclude them from consideration when deciding whether to continue with further investments.
The sunk cost fallacy can easily be overcome with mindfulness, dedicate, and thoughtful planning. Ellingsen, Johannesson, Möllerström and Munkammar[40] have categorised framing effects in a social and economic orientation into three broad classes of theories. Firstly, the framing of options presented can affect internalised social norms or social preferences – this is called variable sociality hypothesis.
A “fixed” cost would be monthly payments made as part of a service contract or licensing deal with the company that set up the software. The upfront irretrievable payment for the installation should not be deemed a “fixed” cost, with its cost spread out over time. The “variable costs” for this project might include data centre power usage, for example. A sunk cost refers to money that has already been spent and cannot be recovered. A manufacturing firm, for example, may have a number of sunk costs, such as the cost of machinery, equipment, and the lease expense on the factory.

A company spends $20,000 to train its sales staff in the use of new tablet computers, which they will use to take customer orders.

The sunk cost fallacy arises when decision-making takes into account sunk costs. By taking into consideration sunk costs when making a decision, irrational decision-making is exhibited.
While these functions are framed differently, regardless of the input ‘x’, the outcome is analytically equivalent. Therefore, if a rational decision maker were to choose between these two functions, the likelihood of each function being chosen should be the same. However, a framing effect places unequal biases towards preferences that are otherwise equal. Taken together, these results suggest that the sunk cost effect may reflect non-standard measures of utility, which is ultimately subjective and unique to the individual.
