What is YoY and QoQ growth?

Year-on-year analysis generally refers to the comparative analysis of the current period and the same period of the previous year. Sequential analysis, in the case of annual reports, is to compare the performance data of the second half of the year with the performance data of the first half of the year. Among them, the performance data for the second half of the year can be obtained by subtracting the interim number from the annual number, dividing the number by the interim number, and then multiplying by 100% to obtain the ratio or range of change from the previous period of change in the reporting period.

Year-on-year growth refers to the comparison with the previous period, such as how much the growth in January this year and January last year, how much the increase was between the 1st of this month and the 1st of the previous month, and so on. For example, the main business income of a company in 2000 was 395364 million yuan, and the main business income in the middle of 2000 was only 266768 yuan, and the main business income in the second half of the year was 128596 yuan, and then divided by 128596 million yuan by 266768 yuan, multiplied by 100 percent, the company's main business income in the reporting period fell sharply month-on-month.

Growth (magnitude) compared to the previous period, previous year, or history. Year-on-year growth calculation formula Year-on-year growth rate (number of current periods and same periods) Number of periods Example For example, the output value in March last year was 1 million, and the output value in March this year was 3 million, how is the year-on-year growth calculated? Is it a year-on-year increase of 200 ?

Or 300 year-on-year ? This question (300 100) 100 200 year-on-year growth rate generally refers to the growth rate compared to the same period last year. Year-on-year ratio of an indicator = (value of an indicator in the current year - value of this indicator in the same period last year) Value of this indicator in the same period last year Comparison with the same period in history, e.g. July 2005 compared with July 2004 is called year-on-year; Comparisons with the previous statistical period, e.g. July 2005 compared to June 2005, are referred to as month-on-month.

There are two methods of month-on-month growth rate and month-on-month development rate. The month-on-month comparison is compared with the previous period's volume. Month-on-month growth rate (number of the current period number of the previous period) The number of the previous period * 100 reflects how much the current period has increased compared with the previous period The number of the current period has increased compared with the previous period The number of the previous period reflects how much the current period has increased compared with the previous period Such as:

The sales volume of the current period was 5 million, and the sales volume of the previous period was 3.5 million The month-on-month growth rate (500-350) 350*100 The month-on-month development rate was 500 350*100

What does year-on-year and month-on-month mean?

First, the scope of comparison is different.

2. Month-on-month growth: that is, compared with the number of the previous period.

Second, the calculation method is different.

1. Year-on-year growth: year-on-year growth rate = (number of the current period, number of the same period) 100% of the same period. Year-on-year growth rate = (value of an indicator in the current year - value of this indicator in the same period of the previous year) The value of this indicator in the same period of the previous year.

2. Month-on-month growth: Month-on-month growth rate = (number of the current period, number of the previous period) 100% of the previous period, and the meaning is different.

1. Year-on-year growth: reflects the development and change of the phenomenon in the same period.

2. Month-on-month growth: reflects the development and changes of the phenomenon in the two periods before and after.

The year-on-year development rate is mainly to eliminate the impact of seasonal changes, and is used to illustrate the relative development rate achieved by comparing the development level of the current period with the development level of the same period last year. For example, February of this period is compared with February of last year, and June of this period is more than June of last year. It is calculated as follows:

Year-on-year development rate (current development level - year-on-year development level) Development level in the same period last year 100% In practice, this indicator is often used, such as the development rate calculated by comparing a certain year, a certain quarter, a certain month with the same period of the previous year, which is the year-on-year development rate.

The month-on-month ratio is divided into daily, weekly, monthly, and year-on-year. The month-on-month rate of development is the dynamic relative figure obtained by comparing the level of the reporting period with the level of the previous period (comparison of adjacent periods). Indicates the degree to which the phenomenon develops and changes over time.

If you calculate the comparison of each month in a year with the previous month, i.e. February vs. January, March vs. February, April vs. March, ......December is more than November, indicating the degree of development month by month.

We often see such expressions in some news, such as "beef** increased by 20% month-on-month, and the company's revenue decreased by 5% year-on-year". What do the "year-on-year" and "month-on-month" mean?

The comparison with the previous statistical period, for example, July 2005 with June 2005, is called month-on-month. Comparison with the same period in history, for example, July 2005 compared to July 2004, is called year-on-year.

These are all statistical terms, and the main difference is that the base period is different.

Month-on-month growth refers to the increase (magnitude) compared to the same period in history, and year-on-year growth refers to the increase (magnitude) compared to the previous period, previous year, or history.

For example, the month of July 2008 is compared to June 2008, which is called month-on-month

July 2008 is said to be year-on-year compared to July 2007.

Ring growth refers to the comparison with the previous period's volumeThere are two methods of month-on-month growth rate and month-on-month development rate. For example, July 2005 is referred to as month-on-month compared to June 2005.

The year-on-year comparison is generally the nth month of the current year and the nth month of the previous year. The year-on-year development rate is mainly used to eliminate the impact of seasonal variations, and is used to illustrate the relative development rate achieved by comparing the current development level with the development level of the same period.

For example, February of the current period is compared with February of the same period last year, and June of the current period is compared with June of the same period last year. The calculation formula is: year-on-year development rate = current development level 100% of the same period level; Year-on-year growth rate = (current development level - same period level) Development level 100%.

In practice, this indicator is often used, such as the development rate calculated by comparing a certain year, a certain quarter, a certain month and the same period, which is the year-on-year development rate.

The difference between year-on-year and month-on-month.

To put it simply, year-on-year, month-on-month and fixed-base ratios can all be expressed as percentages or multiples. The development rate of the fixed base ratio, also referred to as the total speed, generally refers to the ratio of the level of the reporting period to the level of a fixed period, indicating the overall development rate of this phenomenon over a long period of time. The year-on-year development rate generally refers to the relative development rate achieved by comparing the development level of the current period with the development level of the same period of the previous year.

The month-on-month development rate generally refers to the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the phenomenon period by period. Year-on-year and month-on-month, although both reflect the speed of change, due to the different base periods, the connotations they reflect are completely different.

Generally speaking, the year-on-month comparison can be compared with the month-on-month comparison, but the year-on-year comparison cannot be compared with the month-on-month comparison; For the same place, considering the reflection of the longitudinal development trend in time, it is often necessary to compare the year-on-year and month-on-month comparisons.

The year-on-year and month-on-month problems are often encountered in data analysis, and they are also a headache for the majority of public candidatesI don't know how to understand their definitions, let alone how to answer similar questions. I am a middle school mathematics teacher, and I often explain some definitions of mathematics to students in the course, and in the process, I found that many students cannot understand the definition of mathematics well before entering the school, but give some examples that are close to life, and students like and understand. Month-on-month and year-on-year can also be understood in this wayBoth month-on-month and year-on-year comparisons are used to reflect changing trends so that people can analyze the good or bad of some situations and make the right decisions.

Therefore, it is necessary to have a knowledge of year-on-year and month-on-month, which is often encountered in statistics.

The year-on-year definition is a comparison with a certain period (e.g. the same period last year).For example, in 2016, China's oil imports were 19.69 million tons, a year-on-year increase of 15 percent, and the year-on-year comparison here refers to the comparison with the 2015 regret data; In May 2017, China's aquatic product output was 10,000 tons, a year-on-year increase of three percent, and the year-on-year value here is a comparison with the data in May 2016.

Chain is defined as a comparison with the previous statistical periodFor example, in May 2017, China's aquatic product output was 10,000 tons, an increase of 2% month-on-month, and the month-on-month comparison here refers to the comparison with the data in April 2017.

In fact, it can be summed up as "".Year-on-year and month-on-monthIt means that the year-on-year comparison is the year, and the month-on-month comparison is the end time, and you can push it forward by one. The year-on-year data in 2012 is 2011, not month-on-month; The year-on-year increase in August 2016 is August 2015, and the month-on-month increase is July 2016; August 15, 2016 year-on-year is August 15, 2015, month-on-month is August 14, 2016; The first quarter of 2016 is the first quarter of 2015 year-on-year, and the fourth quarter of 2015 is the quarter-on-quarter of 2015.

Summary. Hello, year-on-year refers to the comparison of the current year (quarter, month) with the previous year's year (quarter-month). QoQ refers to the comparison of the current quarter or month with the previous quarter or month.

What is year-over-year growth? What is QoQ growth?

Hello, year-on-year refers to the comparison of the current year (quarter, month) with the previous year's year (quarter-month). QoQ refers to the comparison of the current quarter or month with the previous quarter or month.

For example, for example, the month of July 2005 compared to July 2004 is called year-on-year, for example, the month of July 2005 is compared to June 2005, it is called month-on-month.
