Simple price index is a percentage ratio that represents a comparison for a single commodity. For example, let the price of a calculator is $60 in 2005 and $80 in 2006. To compare the two prices, the price of one of the time periods is fixed as 100 and in this case it is the price of 2005. Therefore 2005 is base period and 60$ is base price. Similarly 2006 is the current period and $80 is current price. This current price is now converted into percentage relative to the base price i.e. 80/60*100 = 133.33%. This percentage is called price relative or simple price index. The concept of simple price index can be elaborated with the help of simple problem.
