When the cpi increases from 200 in 2016 to 210 in 2017 and the nominal wage rate is constant at $10 an hour, the real wage rate Decreases by 5 percent.
First, subtract the CPI from the beginning date (A) from the later date (B), and divide it through the CPI for the beginning date (A). Then multiply the end result by means of one hundred to get the inflation charge percent.
The charging index can then be calculated by dividing the nominal GDP by the real GDP. So if gas became $3 in keeping with a gallon in 2010, then the price index = 3 / 2 × 100 =a hundred and fifty.
The average CPI is the sum over each preparation of the CPI for that guidance expanded through the fraction of the time that guidance is used. For this benchmark, average CPI = (0.11 + 0.02)(3) + (zero.52 + zero.10)(four) + (zero.25)(five) = four.12.
