It is based on the usual fee of a constant basket of goods and offerings bought through a normal consumer, relative to rate of the identical basket in some base year. By consisting of a broad range of lots of goods and services with the constant basket, the CPI can achieve an correct estimate of the value of living.
To discover the CPI in any year, divide the value of the market basket in 12 months t through the cost of the equal market basket in the base year. The CPI in 1984 = $75/$75 x one hundred = 100 The CPI is simply an index cost and it is indexed to a hundred in the base year, in this case 1984.
