Difference Between YoY and YoY 5, Difference Between QoQ and YoY

In December 2006, housing sales in 70 large and medium-sized cities across the country were higher than that of the previous month. In addition to Shanghai, the increase in housing prices in major cities across the country is still high, indicating that the early real estate regulation has not achieved the expected effect.

In fact, the so-called month-on-month comparison mentioned above is simply compared with the previous period in a row. The above is a comparison of annual data, and the month-on-month comparison is the year-on-year comparison; If you do a monthly data comparison, the month-on-month comparison is the comparison of this month with the previous month, that is, the data of the T period divided by the data of the T-1 period. Of course, this is a multiple, if you ask for a month-on-month growth rate, it is the T period data minus the T-1 period data, and then divide by the T-1 period data, multiplied by 100%.

Therefore, the above month-on-month comparison**, which means the house price ** in December 2006 compared with November 2006, is calculated by dividing the average sales of houses in 70 large and medium-sized cities in December 2006** by the average sales of houses in 70 large and medium-sized cities in November 2006.

The month-on-month counterpart is the year-on-year comparison. Year-on-year is a comparison with a small period with the same ordinal number in a large period in the past. It seems a bit complicated to say this, but in fact, to give a few examples, it is the comparison method that everyone often uses:

This October compared to last October, the 50th week of this year compared to the 50th week of last year, and the first week of this month compared to the first week of last month, all of which were year-on-year. In practice, it is generally compared with the same period last year. This is better understood, year-on-year **, which means that the house price in December 2006 is higher than the house price in December 2005**.

The easiest way to distinguish between the month-on-month and year-on-year comparisons is to see if the two periods being compared are connected: the connected ones are generally the month-on-month comparisons, while the year-on-year comparisons are generally not connected. Of course, this is not absolute.

It is easier to see the trend of data on a month-on-month basis, while a year-on-year comparison can eliminate the seasonal factor to a certain extent, so it depends on your own needs which comparison method to use.

For example, in February 2010, TV sales were 1,000 units, a year-on-year increase of 10% and a month-on-month increase of 2%.

We can find that the TV sales volume in 2009 is: 1000 (1+10%) measured in the largest unit year.

TV sales in January 2010 were 1,000 (1+2%) in small units.

Year-on-year is compared with the same period last year, for example, August this year is compared to August last year. The month-on-month comparison is compared to the previous month, and this August is compared to July this year. Of course, the unit here does not have to be a month, it can be any unit of time.

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. The month-on-month growth rate is the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the leading 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.

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?

1. Refer to the following chart, and see that there are two transaction data in December 2012 and December 2011, and the comparison between these two is year-on-year, so we say that December 2012 has increased year-on-year. The increase is based on the 2012 data minus the 2011 data and divided by the December 2011 data.

2. Sometimes we also see the ring comparison. The month-on-month comparison is made with the data from this period and the previous period.

1.Year-on-year refers to the comparison at the same point in time in the adjacent period, 13 years and 14 years are adjacent periods, March 13 and March 14 are the same time points of these two adjacent periods, both are March, and the data comparison between these two periods is year-on-year; So, the order volume in March '14 is 80, and the order volume in March '13 is 70, then we can write like this: the order volume in March '14 increased year-on-year in 13 years.

2.Month-on-month, on the other hand, is relatively simpler, that is, the comparison of adjacent time periods, unlike year-on-year, which is a comparison of the same time point within adjacent time periods; April '14 and March '14 are adjacent time periods, and the data of these two time periods are compared, that is, month-on-month; Of course, we can also compare the data for the whole of '13 with the data for the whole of '14, and this data can also be seen as a month-on-month comparison.

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.

The formula is as follows: year-on-year development rate (current development level - development level of the same period last year) 100% of the development level of the same period last year

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, and April vs. March.

December is more than November, indicating the degree of development month by month.

The so-called year-on-year is the abbreviation of the comparison with the same period of the previous year, and the month-on-month comparison is the comparison of the current period with the adjacent previous period. For example, when analyzing the data in May 2011, the data is compared with the data in May 2010 and compared with the data in April 2011.

Here, the number of periods can also be quarters, etc.

In terms of the annual report, it 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 is the same period last year, and month-on-month is compared with the previous reference period, generally the previous month. It can be distinguished from the literal meaning, the ring is the meaning of continuity, and the same is the same period. China's use of a year-on-year comparison, completely unscientific, last year and this year are a year apart, how much has changed.

10% year-on-year, maybe 20% in one month, and 10% in one month. The year-on-year comparison is ** and the brick family uses it to fool people. What we people care about is how much the price of vegetables has risen this month compared with last month and last week, no matter how much it has increased compared with the same period last year.

Comparison with the same period in history, for example, July 2005 compared to July 2004, is called year-on-year.

The comparison with the previous statistical period, for example, July 2005 with June 2005, is called month-on-month.

Month-on-month growth rate (Number of current periods Previous period) Number of previous period*100 Reflects how much the current period has increased compared to the previous period.

Year-on-year growth rate (current period, same period) Same period number*100 refers to the growth rate compared to the same period last year.

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 from period to period.

The month-on-month comparison is the comparison of the current statistical period with the previous statistical period. Compared with the same period in history, it is called year-on-year.

For example, the comparison between April 2010 and March 2010 is the same as that of April 2010 and April 20094.

To put it simply:

Month-on-month: Yes. Indicators for this year's current period (e.g. July 2017).

Ratio to the previous period of the year (e.g. June 2017).

YoY: Yes. Indicators for this year's current period (e.g. July 2017).

Ratio to the current period of the previous year (e.g. July 2016).

For example, this year's December and last month, that is, November is called year-on-year, and December last year is called month-on-month.

The difference between year-on-year and month-on-month is the difference in the base of comparison. The year-on-year base is the data for the same period of the previous year, while the month-on-month base is the data for the previous period.

The time break point of the month, that is, the comparison of this month in the previous month is called the month-on-month comparison, and the year-on-year time is longer, that is, the comparison with the previous year, I am always confused, and the time is good, and I don't understand how to add my number 491450639

Taking November as an example, it is called year-on-year compared with November last year, and compared with October last month.

In layman's terms, the month-on-month comparison is the comparison between this period and the previous period, such as the comparison between this month and the previous month; Year-on-year is the comparison between this period and the same period of the previous year, such as June 2011 and June 2010.

The difference between year-on-year and month-on-month is entirely the difference in the base of comparison. Due to the incomplete data published, more detailed information is needed to see the discrepancies.

One thing to be clear is that an increase is an increase relative to the absolute value, not a relative increase.

Difference Between Year-on-Year and Moo-Month:

1. The definitions are different.

The month-on-month ratio refers to the comparison of two adjacent months, such as 20 pounds of beef last month, and 24 pounds of beef sold this month, it can be said that beef ** increased by 20% month-on-month; The year-on-year refers to the comparison of historical data for the same period, such as a company's revenue of 1 million yuan in April last year and 950,000 yuan in April this year, it can be said that this month's revenue decreased by 5% year-on-year.

2. The focus is different.

The month-on-month period highlights the short-term trend of the data, which can be affected by seasonal factors such as the season; The year-on-year comparison is more focused on reflecting the long-term general trend, which also avoids the seasonal factor. Vertical celebration.

3. The calculation formula is different.

The formula for calculating the month-on-month period is: (February data of a certain year, January data of a certain year) 100% of the data in January of this year, while the formula for calculating the year-on-year is (January data of a certain year, January data of the previous year) 100% of the data of January of the previous year.

The month-on-month ratio is generally used in the month and day and is rarely used in the year, mainly to compare the degree of increase in a short period of time, but due to industry differences, such as tourism, it will be affected by the off-peak season. Year-on-year is generally used in two adjacent years, in the same time period, to check the degree of increase, generally used in the same month of two years, rarely used in the same date of two months.

The differences between year-on-year and month-on-month are as follows:

First, the meaning is different:

Year-on-year comparisons are made with historical periods. The chain comparison is with the previous statistical period. It reflects the speed of change, but due to the different base periods, the connotation of its reflection is completely different.

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.

Second, the calculation formula is different:

1. The formula for calculating the month-on-month growth (declining brother-on-month) rate in the current period: month-on-month is divided into daily, weekly, month-on-month and year-on-year. The month-on-month growth (decline) rate of Bitan in the current period ( ) in the current period** Previous period**-1) 100.

2. The formula for calculating the year-on-year growth (decline) rate of the current period: the year-on-year growth (decline) rate of Xianhuiqiao in the current period ( ) the current period ** the same period of the previous year **-1) 100.

Year-on-year development rate and month-on-month development speed:

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.

Due to the different base periods, the development speed can be divided into year-on-year development speed, month-on-month development speed and fixed base development speed. are expressed as percentages or multiples.

The year-on-year development rate is mainly to eliminate the influence of seasonal changes, and it is used to illustrate the relative development speed achieved by comparing the development level of the current period with the development level of the same period last year.

The month-on-month ratio is 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. For example, the comparison of each month in a year with the previous month is calculated.
