5.With the passing of time, the value of a product decreases. This is referred to as depreciation. There are many methods to calculate the value of depreciation. And the two important aspects of it are present value and future value.

But many of these methods do not take into account the time value of money. As time goes by, the value of the product depreciates and along with this the value of money might also increase or decrease. Also, attached to this principle is the time. The duration during which the value of a product depreciates.
