So if the value of the price index for the current year is equal to 165, and last year's value was 150, the rate would be calculated as: Inflation rate = (165 - 150) X100= 10.
The inflation rate is calculated using the Consumer Price Index or CPI. To calculate inflation from a month and year to a later month and year, Try our Inflation calculator. We also post the previous Inflation Rates in our Historical Inflation Tables.
