Most of us have a peculiar habit of saving hard for a number of months and spending the accumulated savings at the end of the year in options of our choice. For instance, Mr Kumar, a software engineer, has been saving R20,000 per month for 12 months, thereby accumulating R2,40,000 for the year. Now, he plans to spend these R2,40,000 in some manner.
Here are a few options:
* Buy a brand-new car by taking a loan for the additional amount required;
* Go on a family vacation;
* Buy a piece of land;
* Invest in equity shares directly;
* Invest in markets through mutual funds;
* Invest in a fixed deposit for 3-5 years;
* Buy gold or gold ETFs;
* Take an insurance policy — either an endowment policy or a moneyback policy, or a unit-linked insurance policy
* Spend on buying costly clothing, replacing durables, mobile phone, computer or laptop , and so on.
Present vs future needs
Everyone needs to take a call on whether to fulfill our current requirements or save for future needs. Though we would like to save for the future requirements, for instance, to meet the post-retirement life-cycle requirements, often, we settle with consumption alternatives available in front of us. So, Mr Kumar may prefer to spend his accumulated savings on alternatives of going on family vacation or spending on costly clothings, replacement of durables, computer or mobile or a combination of these two alternatives. Why should he sacrifice the future requirements (which are necessities) to his present luxuries? That’s where the accounting concept of “Just One Fallacy” may hold true.
The Just One Fallacy
When companies manufacture or trade a product or render a service, every extra unit required to be produced/traded/serviced does not give additional fixed cost to the company as long as the extra unit is in the relevant volume range. What such an extra unit of sales adds to the total cost is it’s per unit variable cost only. So, there is a natural tendency for the business unit to ignore the impact of such additional unit of sales under the premise that the fixed cost is a irrelevant for the decision of whether to sell that extra unit or not.
But the problem comes only when the business unit started selling “N” number of additional units, assuming that these additional units do not add additional fixed costs, which is certainly fallacious.
