Sunk cost

I have noticed that we frequently let past decisions keep us from future opportunities. Let me explain what I mean by that statement. We worry too much about the ‘sunk cost’. A sunk cost is when you have already spent time or money, which can never be recovered, on something. I like to include them in the definition of sunk cost, primarily because time is a resource that once spent is gone forever.

An example of a sunk cost is you bought a season pass to a swimming pool. You can never recover the money spent on the pass, all you can do is utilize it to maximize your enjoyment. The money is gone, regardless of how often the pass is used.

One of the most common statements I hear goes something like, “We spent $xxx to do ____, so we cannot do ____.” Now if you fill in the blanks the statement might be, “I spent $10,000 on the car, it is now worth $7,000, so I cannot sell the car because I cannot get what I paid for it.” This is the sunk cost syndrome. We might be clouding our decision making by hanging on to the sunk cost. Maybe the outlook needs to change too, “I can get $7,000 if I sell the card today.” The idea is to not worry about what you spent but to focus on what you need to do moving forward. Another way to view this is to ask, would you make the same decision today?

Sunk cost syndrome creates a situation where we are hesitant to change direction or consider alternatives that had we not worried about the past decision the choice would be simple as well as different. I would suggest that when considering options try to avoid the sunk cost trap and don’t let past, unreversable costs stop what you have planned for the future.
