1. The purchase price is the cost of buying a stuff but we often forget that it carries some sales tax. The sales tax increases as the value of the item increases. If the item is bought through credit cards, the price would carry interest and other charges.
2. The opportunity cost is the cost of money you lose for choosing one item over the other. This is always true because no matter how rich you are, you can’t have everything and would always make a choice.
3. Most items entail maintenance costs in order to make it operational all the time. Even decorative items need to be dusted at least once a week.
4. Smart buying requires time for comparing prices. Because of the many considerations in buying, such as maintenance and disposal, time has a price. How much it would be depends on what kind of a person you are.
5. More items need more storage areas. Some would even resort to renting a storage area.
6. Worrying about your stuff has a price. The stress of setting them up or storing them costs much. The difficulty of parting with pre-loved items has an even higher price.
This should help you realize how much your stuff actually costs you.
