How to calculate the average annual growth rate, and what is the formula for calculating the average

The growth rate of the data in n years = [(current period before n years) -1] 100% formula explanation. The current period is the first n years.

It should be the end of the current year and the end of the previous n years, where the end of the previous n years refers to the end of the penultimate nth year excluding the current year, for example, to calculate the four-year asset growth rate at the end of 2005, the calculation period should be four years, but the end of the previous four years should be the end of 2001. The parentheses are for the composite growth index for n years, not the growth rate.

It is the square of the n-year total asset growth index in parentheses, that is, the index is averaged. Because the values in parentheses include the cumulative growth of n years, which is equivalent to compound interest calculation, they should be averaged. It should be noted that the number of open squares should be n, not n-1, unless the end of the previous n year is changed to the beginning of the previous n year.

In short, the number of open squares must match the number of periods corresponding to the composite growth index in parentheses. And how to define the formula can be understood by the user.

1/(n-1)]-1

Subtract 1 because the comprehensive growth index calculated in parentheses includes 1 of the base period, and after the opening of the square, it is the average annual growth index, which is still greater than 1, and what we need is the average annual growth rate, that is, only the incremental part is examined, so the 1 of the base period must be removed, so 1 must be subtracted

What is the average annual growth rate?

Answer: How to calculate the average annual growth rate? If the data of a single indicator or multiple indicators has a long time span, the calculation of the average annual growth rate will more intuitively reflect the growth rate of this data or a group of data. Tool raw materials excel method step by step reading 1 5 Open excel and select the data of the beginning and end of the indicator or select the data within the corresponding time according to your needs (in this example, the unit is in the span of years) 2 5 Type "=power()" in the corresponding box 3 5 As shown in the figure, type "=power(Select period data Base period data, 1 (select period - base period - 1))-1" ("*100" after the formula is to directly display the percentage without a percent sign) 4 5 Click enter to get the average annual growth rate 5 5 If it is a set of data, and the same time selection, you can directly pull it down.

Note: The average annual increase of several years should be noted that there is no increase in a single year, at least two years or more, or more than 2 time periods to type the formula, you need to double-click the formula that automatically appears in the program below the typing box, so that the formula can go up The content is for reference only and is protected by copyright Formula: The growth rate of the data in n years = [(current period before n years) -1] 100%. Average annual growth rate is a statistically related concept, also known as compound growth rate.

It is common in the population** and refers to the average annual growth rate over a certain number of years.

How to calculate the average annual growth rate:

One is to calculate the two-year average growth rate using excel:

Since it is enough to calculate the two-year average growth rate with excel, the formula can be written as: sqrt(c a)-1, sqrt is the open square function of excel, so you can use this formula to calculate the two-year average growth rate in excel.

The second is to use excel to calculate the multi-year average growth rate

The formula is: power(10, log10(c a) n) function is to return the power of a given number, power(10, log10(c a) n) is equivalent to 10 log10(c a) n, which is log10(c a) n power of 10.

log10 is the logarithm of any number with 10 as the base, and you can calculate the average growth rate for any number of years by writing this formula into the cell where excel calculates the average growth rate.

Windows comes with a calculator to open the root number to calculate:

1. Click on the view bar of the calculator navigation, select the scientific calculator item, enter 49, and select the "X Y" key. Then enter, and finally press " " to get the result is 7, the principle is 49 to the power is the root number.

2. Also click on the view bar of the calculator navigation, select the scientific calculator item, enter 49, check the "inv" checkbox, then select the "x y" key, then enter 2, and finally press " " to get the same result as 7.

The average annual growth rate is calculated as: m = <>

where B is the last year, A is the first year, and M is the average annual growth rate.

In fact, considering b = a (1 + m)n, then it is a process of solving m.

Examples:

Since 2001, the number of visits to key news has increased by an average of 12% per month. China's internet industry currently contributes 7% to GDP and is likely to reach 15% in the next three years.

a． b． c． d．

Analysis] This argument is the average annual growth rate of the test, and the change of the question is the average annual growth rate of 2001 and 2002. Assuming that the number of visits to Qingling in December 2000 is 1, then December 2001 is 1 (1+12%)12, then the average annual growth rate is 1 (1+12%)12 1-1=.

The average growth rate is the average rate at which a phenomenon increases over a long period of time. The average rate of development is the average rate at which the phenomenon develops from period to period.

There are two methods for calculating the average growth rate in China: one is the "horizontal method", also known as the geometric average method, which is used to calculate the average annual growth (or decline) rate by comparing the level of the last year of the interval with the level of the base period; The other is the "accumulation method", also known as the algebraic averaging method or the equation method, which calculates the average annual growth (or decline) rate by comparing the sum of the annual levels in the interval with the base period levels. Under normal circumstances, the average annual growth rate calculated by the two methods is relatively similar; However, when the economic development is unbalanced and there are big ups and downs, the results of the two methods are quite different.

Except for the investment in fixed assets, which is calculated by the "accumulation method", the rest are calculated by the "horizontal method". The years from a given year to the average growth rate of a given year do not include the base period year. If the average growth rate in the 43 years since the founding of the People's Republic of China is calculated based on 1949, it is written as the average growth rate from 1950 to 1992, and so on.

Hello dear, I am happy to answer for you: the answer is: dear, the annual growth rate is calculated and then added and divided by 3, which is the average growth rate of Zen Oh, the average annual growth rate is actually for the convenience of calculation, and the average growth rate calculated together for several years artificially set.

The special circumstances of individual years are excluded here, and the average growth rate should not be used in more detailed financial calculations. : Average growth rate = where the growth rate of the numerator is the total quantity of a and the denominator is the growth rate of the total number of copies is b.

Average growth rate = (end of the period - initial amount) open n to the power n represents the time It can be expressed as follows: Average annual growth rate = total number of years of growth 100% of the number of years. The growth rate has to be multiplied by 100% at the end. Vertical balance.
