Construction of price index numbers through various methods can be understood with the help of the following examples: 1. Simple Aggregative Method: In this method, the index number is equal to the sum of prices for the year for which index number is to be found divided by the sum of actual prices for the base year. Calculating Consumer Price Index. Divide the price of the basket of goods in the year for which you are calculating CPI by the price of the basket of goods in the base year and multiply the result by 100 to calculate the CPI in that year. Using an index to measure changes in data allows you to calculate the percentage change between the points in the index without the need to know the actual data numbers. The index points become normalized when dividing each number by its base value, meaning that the values on different scales become converted into a common scale for ease of comparison. To calculate CPI, or Consumer Price Index, add together a sampling of product prices from a previous year. Then, add together the current prices of the same products. Divide the total of current prices by the old prices, then multiply the result by 100. Finally, to find the percent change in CPI, subtract 100. The index is then calculated by dividing the price of the basket of goods and services in a given year (t) by the price of the same basket in the base year (b). This ratio is then multiplied by 100, which results in the Consumer Price Index. In the base year, CPI always adds up to 100. This becomes obvious if we look at our example.
