What is the first thing that almost any personal finance blogger that tends to align themselves in “Camp Frugal” will tell you when it comes to saving money? Most likely it is a variation of the mantra, “Spend less! Save, save, save! Quit spending money!” Is this really the best way? It seems that many people, myself included, can leave an important variable out of the cost saving and wealth maximizing formula. This “missing variable” is opportunity cost.
Opportunity Cost Explained
What exactly is opportunity cost? Let’s say that you have two different things that you could do with an hour of your time: Activity A or Activity B. You can only choose one of them but not both. If you choose to do Activity A then you cannot do Activity B and vice versa. If Activity A is your #1 choice for what you would choose to do for that particular hour and Activity B is your #2 choice then when you choose to do Activity A, and are therefore excluded from doing Activity B as well because remember you can only choose one or the other, your opportunity cost is the cost to you in not being able to partake in Activity B.
The technical definition of opportunity cost is therefore the cost of the next best alternative (the thing that you have given up) whenever you are making a decision between two or more mutually exclusive choices.
It’s important to remember that opportunity cost is not necessarily always measured in financial terms (although it is a smart thing to do to ultimately convert all opportunity costs into a financial measurement so that you can better compare options).
Let’s take a look at some different scenarios to see if strictly adhering to the “Spend Less” rule in all circumstances is the best way to go or if there are times when taking a closer look at the opportunity costs involved might help us to improve upon our cost savings and wealth maximizing “formula” and ultimately create wealth and skyrocket our net worth even faster.
