What is a Sunk Cost?

The sunk cost definition is money your business already spent and cannot recover. With sunk costs, a business cannot sell what it purchased to recoup the costs. Maybe you went to law school, passed the bar, started working, and then realized you hate being a lawyer. You invested so much time, energy, and money in that degree, so it can’t be worth starting over again with a new career, right? Unfortunately, these are all sunk costs, so if your end goal is your own happiness, you might need to cut your losses and refocus your energies elsewhere.

At some point, the rent may become an expense you can’t recover through your shop’s profit (a sunk cost). But after spending so much money on repairs, you decide you’d rather fix the old car so that the money you spent previously wasn’t all for nothing. You believe that you “invested” a lot of money into the car, and you don’t want to “lose” it by getting a new one.

Evangelizing a new feature or product and motivating others around them are central to the PM role.

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. Sunk costs are excluded from a sell-or-process-further decision, which is a concept that applies to products that can be sold as they are or can be processed further. In financial accounting, sunk costs must have already occurred and they cannot be changed or avoided in the future. This does not apply to rental equipment; rental costs are only fixed until the renter decides to discontinue use. In this example the Project Manager will exclude the 800k already spent (the ‘bygones) and also the 300k of future fixed costs which cannot be recovered no matter what happens.

How Does This Cost Impact Product Management?

The cash value of the stock rewards may not be withdrawn for 30 days after the reward is claimed. Experimenting with new recipes is a part of research and development. You spend $100 on materials for one potential new product, and nobody purchases the product. After a test run, the customer feedback is that the new product is not something you should sell.

  • Rationally, they should consider earlier investments to be sunk costs, and therefore exclude them from consideration when deciding whether to continue with further investments.

  • A fixed cost, however, is not a sunk cost, because it can be stopped, for example, in the sale or return of an asset.

The bygones principle is grounded in the branch of normative decision theory known as rational choice theory, particularly in expected utility hypothesis. If, for example, XYZ Clothing is considering shutting down a production facility, any of the sunk costs that have end dates should be included in the decision. To make the decision to close the facility, XYZ Clothing considers the revenue that would be lost if production ends as well as the costs that are also eliminated. If the factory lease ends in six months, the lease cost is no longer a sunk cost and should be included as an expense that can also be eliminated. If the total costs are more than revenue, the facility should be closed.

Economists suggest that, in theory, sunk costs are not relevant to future decision-making. In practice, however, sunk costs can and do significantly influence decisions about the future. This is largely because it’s psychologically challenging to let go of previously invested time, effort, or financial resources even if the outcome of those investments fails to meet expectations.

Difference Between Opportunity Cost, Sunk Cost and Relevant Cost

The sunk cost fallacy is the tendency for people to continue an endeavor or course of action even when abandoning it would be more beneficial.

Sunk costs are fixed and do not change irrespective of the levels of productivity of a project or operation. If you decide that you have to proceed with manufacturing because you’ve already “invested” money to develop the product, you’d be buying into the sunk cost fallacy.

They pay for the factory up front and expect to earn a certain level of cash flows from the factory’s production each year. But after a few years, the factory is underperforming and cash flows are less than expected.
