• In calculating GDP, we can either sum up In calculating GDP, we can either sum up the value added at each stage of the value added at each stage of production, or we can take the value of final production, or we can take the value of final sales. We do not use the value of total sales. We do not use the value of total sales in an economy to measure how much sales in an economy to measure how much output has been producedoutput has been produced..

For base year 2000, we divide the base price of bread by itself, $1.25 / $1.25 price index for 2000 equals 1 100 = 100 the price index in the base year is always 100. The price index for 2001 is $1.30 / $1.25 = 1.04, which when multiplied by 100 = 104, and for 2002 it is 112.

Thus, the index is 4% higher in 2001 than in the base year, and 12% higher in 2002 than in the base year.
