1. You need to determine the start year and end year of three years. If the growth rate is calculated from 20 18 to 2020, the starting year is 20 18 and the ending year is 2020.
2. Calculate the total growth rate of sales revenue in three years. The total growth rate of sales revenue in three years can be obtained by subtracting the sales revenue in the beginning year from the sales revenue in the end year and dividing it by the sales revenue in the beginning year.
3. Calculate the average growth rate. Divide the total growth rate of sales revenue in three years by three to get the average growth rate. For example, the sales revenue of a company is 20 18, 1 10,000 yuan, 20 19,10.5 million yuan, and 20.202 billion yuan.
4. The total growth rate of the company's sales revenue in recent three years is (200-100)/1,that is, 100%, and the average growth rate is 1/3=0.3333, that is.
