How to calculate the year-on-year growth rate?

Year-on-year growth rate = (index value of the current year-value of the same period last year) ÷ value of the same period last year * 100%.

The year-on-year growth rate generally refers to the growth rate compared with the same period last year. Year-on-year growth rate (range) compared with the previous period, year or history.

The development speed can be divided into year-on-year development speed, ring-on-ring development speed and fixed-base development speed due to different base periods. Expressed as a percentage or multiple.

Extended data

The year-on-year development speed is mainly to eliminate the influence of seasonal changes. By comparing the current development level with the development level of the previous year, the relative development speed is explained. For example, this February is more than last February, and this June is more than last June.

Its calculation formula is: year-on-year development speed = (current development level/last year's development level-1)* 100%. This indicator is often used in practical work. For example, the development speed calculated by comparing a certain year, a certain season and a certain month with the same period of last year is the year-on-year development speed.

The development speed of fixed base ratio is also called total speed, which is the ratio of the level in the reporting period to the level in a fixed period, indicating the total development speed of this phenomenon in a long period. For example, during the Ninth Five-Year Plan period, the annual level was compared with the level of 1995, and the monthly level of a year was compared with the level of 65438+February of the previous year, which was a fixed development speed.
