Sunk Cost

Definition of Sunk Cost

A sunk cost is a financial term that represents money that has already been spent and cannot be recovered. Thus, while it might pull at your heartstrings (or your budget), it shouldn’t be a factor in your future financial decisions. Remember, once it’s gone, it’s like the last slice of pizza at a party—you want it, but it’s just not coming back!

Example of Sunk Costs

Salaries: You’ve paid your staff for the month, but if sales drop, you don’t get that money back!
Insurance: If your insurance premium has been paid up front, it’s sunk. You can’t ask for a refund because your house didn’t have a barbecue party every weekend.
Nonrefundable Deposits: If you leave a nonrefundable deposit for a venue, that’s a sunk cost—you can’t reclaim that money, even if you decide to cancel.

Relevant Cost: Future costs that will be incurred and can affect the decision-making process.
Sunk Cost Fallacy: The tendency to continue investing in a losing proposition due to the amount already invested, like stubbornly trying to finish a bad movie just because you paid to see it!
