There is a term used in business, cost of ownership. It includes all costs of buying, using and maintaining some equipment. When you know the cost of ownership and resource of the equipment you can calculate the cost of each use. You can do the same for common things, including clothing. A piece of clothing or footwear may appear expensive but it may be used frequently and long. In that case each time you use it will be cheap.
