How Sunk Costs Keep You Stuck in Bad Investments

Sunk Costs Keep You Stuck in Bad Investments

Last fall, I had tickets to an NFL game. It was freezing that day, and all my friends backed out. But I didn’t want to waste the $70 I’d spent on the ticket. So I went to the game and was absolutely miserable. I hate to admit it, but my friends were right.

I didn’t even have much vested interest in the teams playing. Nor did I have a good time at the game; I would’ve been much better off just watching it from the comfort of my couch. But I was obsessed with not having wasted the money I spent on the ticket. In hindsight, I know I should have recognized that it was a sunk cost, chalked up the loss and moved on. I shouldn’t have let it cloud my judgment.

But when it comes to sunk costs, our instinctive opposition to “wasting money” we’ve already lost can hurt us in many ways. In investing specifically, it can make you hold on longer than you should, and cost you even more.

What ARE Sunk Costs?

A sunk cost is money that we’ve already spent, and that we can’t get back. Sunk costs bias our future behavior. It weighs on our minds and keeps us from making rational decisions. Sunk costs keep us in investments that we otherwise would’ve abandoned long ago. We use sunk costs to justify our past choices, but they can keep us from moving forward.

And whether we realize it or not, sunk costs are everywhere. If we look hard enough, we can see them in a lot of our decision-making. I can’t even begin to count the number of stocks I’ve bought that have lost money. I’ve been stuck with the choice of either selling for a loss or trying to buy more to lower my cost basis — which can be throwing good money after bad.

But the money that you’ve spent on a stock purchase shouldn’t factor in your next decision. You should know what conditions would lead you to sell a stock before you buy it. What if the reason you thought it was going up doesn’t pan out? What if the company has a bad quarter? Or the company’s management decides to go in a different direction than you expected? Before you even buy a single share of stock, you need to have an exit plan.

You have to sell your stocks — or hold them — based on rational criteria. The amount of money you spent when you bought them should not be a factor. That money is gone. It’s a sunk cost. Ignore it, and consider only whether an investment is a good or bad deal looking ahead when you make the next decision about what to do with it.

Time Shares: A Classic ‘Sunk Cost’ Conundrum

Have you ever bought a timeshare? If so, you’re not alone — millions of Americans own them. The problem is that they’re typically poor investments that lock buyers into long-term agreements to visit the same vacation destinations each year. They’re incredibly illiquid, and they’re expensive.

Timeshares also come with hefty maintenance fees that you have to pay every year, even if you don’t use your annual points toward a vacation. Many people dream of getting rid of their timeshares, but they can’t — or think they can’t, because of their sunk costs.

So why do we continue to hold onto these poor investments? It’s because we’ve already spent so much money on them; we dread losing the “benefit” from it — even when it’s not such a benefit at all.

  1. Hank couldn’t agree more. Aversion to taking a loss and moving on to a better investment is a real issue for some investors. The question to ask is “… would you buy this today?” If no move on, take your loss if applicable and learn from this.

    Now an NFL game is another matter, at least if it is at Lambeau or the Packers are involved. Thank goodness for the NFL ticket exchange and stub hub LOL.

  2. Well, I felt compelled to comment given my blog name. Yeah, you should’ve just swallowed the ticket costs. The cost was irrelevant at the time of the decision to go or not go. Given the chance to be miserable or warm, you took the risk on misery probably in the hopes of seeing some spectacular play or comeback. I frequently encounter this same decision with friends offering me tickets to basketball games when I can just sit in the comfort of my home with my big screen and a beer. Most of the time I just watch on TV, and I’ve done that a couple of times when I’ve paid for tickets too.

  3. Sunk costs are a real problem. I would have also struggled to give up going to that football game. When you’ve already committed to something financially, its so difficult to let it go as a lost cost. I have managed to stay away from time shares after hearing so many unhappy customers with that particular experience.

  4. When i make a mistake with money that is a sunk cost, i just say “Oh well,” and hopefully learn not to do that again. I learned long ago that grieving over a sunk cost does no one any good.
