How do you calculate annual inflation rate?
Calculating the Inflation Rate. Divide the price at the end of the period by the price at the start of the period. For example, if you wanted to measure in the annual inflation rate of gas over eight years and the price started at $1.40 and went up to $2.40, divide $2.40 by $1.40 to get 1.714285714.
