Calculate Financial AND Opportunity Costs of Your Decision

Today, let’s talk about opportunity costs. It’s a term you often hear in the business world in relation “the cost of an alternative that must be forgone in order to pursue a different action“. But it most certaintly relates to your personal finances as well. Can you think of some? I can. For example:

The MINI Cooper and Opportunity Cost

mini cooperYou’ve read recently that we bought Stacie a new MINI Cooper. That’s a lump sum of about $13,000 plus another $6,000 at 0% on a credit card. It will all be paid off by December or January (the larger amount probably next week), but let’s look at this purchase in a different light. A number of commenters have lambasted the decision because they saw it as a frivolous waste of money when we could have gotten a much cheaper car (or no car at all). I accept your reasoning.

What else could we have done with that $19,000? Well, a lot of things:

  • Saved it and earned interest
  • Invested it
  • Donated it
  • Paid down other debts
  • Used it for a much-needed vacation to our favorite destination…Ireland
  • Used it for home repairs or upgrades like those wood floors
  • Saved it, earned interest and bought a car in a year

The list can go on and on, but this is the short list that we considered after selling our Malibu and pocketing almost $12,000. So, why didn’t we go on that trip to Ireland? Why didn’t we invest it towards our retirement? Why didn’t we install hardwood floors and increase our home’s value? The answer is:

Stacie has wanted a MINI Cooper for over 4 years.

Let me explain. I’m not a math lover, so in my purchases I don’t always bother with running the hard numbers to come to a sound decision. Why? Because numbers only explain part of a purchase. The rest is emotion and logic (math is part of the logical thinking). Opportunity cost is also more than just calculating numbers.

We’re really considering whether we can afford a trip to Ireland this January when I have a break from school, but I doubt we’ll go. We don’t have the money, although we could save it up fairly quickly. However, it would put a big dent in our debt repayment plans. But couldn’t we have used part of that $12,000 from the Chevy sale towards the trip? Yes. Well why didn’t we?

Because a 10-day trip to Ireland would give us memories for a lifetime, but we’ve already been to Ireland (for our honeymoon). It was time for Stacie to finally own and drive a car that she would love.

I’ll talk about our car mistakes in another article, but for this one, I’ll at least say that we should have just gotten her the car she wanted back in 2004 when we were first looking. Tens of thousands of dollars later, we finally got it and she smiles every morning as she thinks about her 20 mile commute into work. She smiles every day she leaves the office and walks towards her blue MINI. The Malibu never did this to her. The Pontiac never did this to her. The Passat never did this to her. (I never did this to her when we commuted together for 9 months).

We’ve forgone a number of other opportunities in order to get the MINI. Had we spent $4000-5000 on a trip to Ireland, we couldn’t have afforded a new(to us) car. The trip to Ireland would have given us a lot of memories, but the MINI can take us to those memories, although we’d have to drive really fast to skim across the Atlantic Ocean to Ireland! Both would make my wife smile, but the MINI also provides functional utility, while Ireland would be captured in our memories, photos and videos.

We haven’t ruled out another trip to Ireland, but we have to factor in our debt repayments, school costs, regular costs of living and more, just like we did when considering the MINI purchase. Granted, I thought through all of them very quickly prior to buying the MINI, but I don’t want you to think it was an impulse purchase. We were thinking of the MINI well before we even sold the Malibu. We just thought we would buy a brand new one in another year.

Opportunity Cost in Your Daily Life

Every minute of the day you are calculating opportunity cost. You’re betting that sleeping in later is a better opportunity than going into work, or going to the gym. You’re calculating that reading this article is a better use of your time than writing one for your own site, or starting up your own site if you don’t have one. You’re calculating that spending time with coworkers at lunch is worth the $7-12 that you could have used to pay down debt or invest.

Opportunity cost calculations are part of every second of our lives. There’s always something better we could do with our time or money, but it’s up to YOU to calculate how that other thing is better.

You can figure out how much your time is worth, use that in all your comparisons, and then calculate the future benefits of the decision. For me, I had to determine whether spending about 15 hours or more per week in school or doing schoolwork for the next 2+ years is worth my time and money. The current cost is, of course, my time and money, but the future payoff is increased earnings and job opportunities. It’s hard to put a hard number on future payoff without some historical data, and even then the results are sketchy, but it’s worth it for big decisions.

One last major opportunity cost that I’ll bring up is one that many of my readers are very well familiar with: kids. We’ve done our own analysis of having kids, and continually reevaluate the decision. I’ve stated already that kids are probably THE biggest impact to your lives. Opportunity cost calculations and decisions abound when talking about kids.

Now I want to hear from you. What opportunities did you miss by choosing to do something else? How do you calculate opportunity cost?

  • I decided to buy a house, which means that I’ve postponed my dream of travelling on the Trans-Sib express. However, I’m pleased with my house on a daily basis, and the trip would only last 3 months. I can still save up and go, its just going to take me longer.

  • Check Art Frommer’s Blog that lists a cheap trip to Ireland for $699 per person, including Air, Car rental, B & B’s from DC. I actually did a trip through Sceptre Tours in 2003 (during winter break while I in grad school) & we had a blast. If you search his blog he also has details on $499 person but unsure if those leave from DC.

  • Dave, I’ll definitely have to check it out. We would drive ourselves and we’d be able to stay at a (very) distant relative’s place for a couple nights in the southwest. The airfare I found through Aer Lingus was about $650 just for one person after fees and taxes.

    Plonkee, a house is a good buy, however that is yet another thing that’s absorbing our money that could be used elsewhere. Good thing you brought that up.

  • I actually did the reverse. I had a couple grand coming to me and instead of immediately putting it in my ING account (as per usual for me) I threw my fiancee and me an awesome weekend at a Sofitel hotel suite, a dinner cruise, theater tickets, shopping, etc. It was a weekend I will probably never top but one we will never forget.

    Every so often though I wonder . . . what would that $2000 look like now, compounded?

    But we all have to live brothers.

  • You also have to weigh the opportunity cost of taking a trip to a place to which you’ve already traveled.

    My wife and I really want to go back to Italy, but there are so many other places we want to see (Spain, Greece, China, Australia, etc) that it makes it hard to justify going back so soon.

  • Interesting topic and I felt the need to give my perspective. You say “There’s always something better we could do with our time or money, but it’s up to YOU to calculate how that other thing is better.”

    Maybe I am not seeing your point but I would disagree with that statement. For me life would really suck if it were true. I would never be happy with where I am. Instead, I try to focus on getting the most out of the opportunites that I have pursued, both financially and personally. And yes, kids will have the biggest impact on your lives if you and your wife decide to have them. But the good news is that I guarantee you will never ponder the lost opportunity of being somewhere else when you are holding them in your arms!

  • Kyle, not sure what your disagreement is to the statement you quoted. Basically, I can’t calculate what you lost in opportunity by the choice you made due to the emotional and immaterial aspect to decisions in general.

    Of course we don’t want to sit and worry whether we should have done something else though. That would be a major waste of time and our brain power. Yes, make the most of the decisions you made, but this article speaks to the time before making those decisions. It’s about calculating (mentally or even on paper) the weight and risk of each situation before committing. Obviously, though, you don’t pull out a supercomputer to decide between 2 types of gum. You need to scale your calculations to the decision at hand.

  • Thanks for the response. The part where you say “There’s always something better we could do with our time or money” is what I was disagreeing with. The point I was trying to make is that there are times when there is ‘not’ something better that I would want to do with my time or money. Whatever it may be, spending time with family, helping a charity, etc. But I think what you are saying is even with such choices there are still opportunity costs associated with them. Interesting, never thought about it that way.

  • opportunity costs don’t matter if it is a purchase you want and budgeted to obtain. money is in fact to purchase goods and services, it isn’t to hoard away for the sake of hoarding. it may not have been what other people would have done with their money, but you weren’t talking about their money in the first place. enjoy the mini, get on with the next goal.

  • Very well said! I’m looking at a similar problem now, though on a much smaller scale- trying to decide if I should go ahead with the purchase of a new laptop and delaying paying off more debt.

    I agree with you, there is always something ‘better’ we could do with our money- better in the sense of making it earn more dollars- but then, that’s not what life’s all about either.

  • OK I wanted to vote for you but I’m a bit inept with these things. Plus I tried to go directly to the link from my feed reader and websense thought you belonged in the category “sex” – which, obviously, is filtered.
