In India, inflation is measured by the two major indices. They are the Consumer Price Index (CPI) and Wholesale Price Index (WPI). Let us first know what is meant by inflation.
A calculated surge in the average prices of goods and services for a longer duration in the economy is called inflation. It is a macro concept, wherein the effect of inflation is seen over a large basket of goods. The total effect of inflation is recorded as the value of money is reduced that is the purchasing power of money is reduced.
