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 an introduction to geometry 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.
