How was the CPI calculated in the previous year? What is the basis for the calculation?

CPI is calculated by CPI = (the value of a set of fixed goods in the current period**) divided by (the value of a set of fixed goods in the base period**) multiplied by 100. For example, if in 1995, the cost of an ordinary household to buy a group of goods per month was 800 yuan, and the cost of buying this group of goods in 2000 was 1000 yuan, then the consumption index of the country in 2000 was (based on 1995) CPI = 1000 800 * 100 = 125, that is** 25% of the total. In everyday life we are more concerned with the inflation rate, which is defined as the percentage change in the ** level from one period to another, the formula is t=(p1—p0) p0, where t is the inflation rate of the 1 period, and p1 and p0 represent the ** level of the 1 period and the 0 period respectively.

If the level is measured by the consumption index described above, the inflation rate is the percentage change in the consumption index over different periods. If an economy's consumption index increases from 100 last year to 112 this year, then the inflation rate in this period is t=(112-100) 100*100%=12%, that is, the inflation rate is 12%, which is manifested as 12% of prices**12%.

One of the groups of commodities is a combination of a number of commodities.

The formula for calculating CPI is:

CPI = (value of the same group of fixed commodities calculated by the current period ** Value of the same group of fixed commodities calculated by the base period **) 100%.

Judging from the formula, the data of the current period is generally fixed; Therefore, the choice of base period data determines the final result of CPI data

Calculation formula:

CPI = (the value of a set of fixed commodities in the current period ** divided by the value of a set of fixed commodities in the base period**) 100.

CPI indicates how much more it would cost the average household to buy a representative set of goods today than it did sometime in the past.

For example, if in 1995 the average household in a country spent 1,000 yuan per month on a group of goods, and in 2000 the cost of buying this group of goods was 1,100 yuan, then:

Taking 1995 as the base period, CPI 1995 = (1000 1000) * 100 = 100, CPI 2000 = (1100 1000) * 100 = annual inflation rate = (CPI 2000- CPI 1995) CPI 1995) * 100% = 10%, and so on.

What the change in CPI says about it.

In the case of a large increase in the CPI economic index, there will be a large increase in market prices, and the value of money in the hands of residents will shrink. Resulting in a decrease in market investment funds, it will lead to a lack of upward momentum, and it is very likely to occur**or adjust**. A large increase in CPI economic indicators will also lead to the introduction of interest rate hikes by banks to curb the CPI indicators, which will be bearish for the market.

CPI is a macroeconomic indicator that reflects the changes in the level of consumer goods and services related to residents' lives, and is mainly used for macroeconomic analysis and decision-making and national economic accounting indicators. If there is a large increase in the CPI economic indicators, it means that there is a possibility of inflation in the market and the market economy is unstable.

As a result, there is a risk that the bank will have a monetary tightening policy and a market fiscal policy. In general, when the CPI economic indicator increases by more than 3%, it indicates that there is inflation in the market. If the increase is greater than 5%, it indicates that the market is in a state of severe inflation.

The formula for calculating CPI is CPI = (the value of a fixed commodity calculated by the current period) divided by (the value of the fixed commodity by the base period) multiplied by 100 cpi

I'll give you an example

In 1995, the cost of an ordinary household to buy a group of commodities per month was 800 yuan, and in 2000, the cost of buying this group of commodities was 1,000 yuan, so Lu Yuankuan's 2000 de-cracking fee ** index was (with 1995 as the base period).

That's 25%.

Do you understand it, if you understand it, give points.

CPI = (the value of a set of fixed commodities in the current period ** divided by the value of a set of fixed commodities in the base period**) 100. For example, if in 1995, the cost of an ordinary household in a country to buy a group of goods per month was 1,000 yuan, and the cost of buying this group of goods in 2000 was 1,100 yuan, then: taking 1995 as the base period, 1995 = (1000 1000) * 100 = 100, 2000 = (1100 1000) * 100 =110。

That is: inflation rate in 2000 = ((2000-1995) 1995) * 100% = 10%.

The Consumer Price Index, abbreviated as CPI, is a price change index based on the statistics of products and services related to residents' lives, and is usually used as an important indicator to observe the inflation level. Since January 2011, China's CPI has begun to calculate the ** index series with 2010 as the base period. CPI = (value of a group of fixed commodities calculated by the current period ** Value of a group of fixed commodities calculated by the base period **) 100%.

If in 1995, the cost of an ordinary household to buy a group of goods per month was 800 yuan, and in 2000 the cost of buying this group of goods was 1000 yuan, then the country's consumption index in 2000 was (based on 1995) CPI = 1000 800 100% = 125%, that is to say, ** (125-100)% = 25%However, it has regional differences. Proportion of CPI constituent items:

Food 34%, entertainment, education and cultural services 14%, housing 13%, transportation and communications 10%, health care 10%, clothing 9%, household equipment and maintenance 6%, tobacco and alcohol 4%.

CPI Calculation Method:

CPI = (value of a group of fixed commodities calculated by the current period ** Value of a group of fixed commodities calculated by the base period **) 100%.

The fixed weights are calculated according to the weighted arithmetic mean formula, i.e., k'= kw w, the fixed weight is w, where k of the numerator in the formula is the individual index of various sales volumes.

CPI is the abbreviation of the Household Consumption Index. The Household Consumption Index is a macroeconomic indicator that reflects the changes in the level of consumer goods and services purchased by households. It is a relative number that measures the change of the **level of a group of representative consumer goods and services over time, and is used to reflect the change of the **level of consumer goods and services purchased by households.

For example:If in 1995, the cost of an ordinary household to buy a group of goods per month was 800 yuan, and in 2000 the cost of buying this group of goods was 1000 yuan, then the country's consumption index in 2000 was (based on 1995) CPI = 1000 800 100% = 125%, that is to say, ** (125-100)% = 25%However, it has regional differences.

CPI is an important macroeconomic indicator that reflects the changes in the level of consumer goods and services related to residents' lives, and is also an important indicator for macroeconomic analysis and decision-making and national economic accounting. Generally speaking, the level of CPI directly affects the introduction and intensity of the country's macroeconomic control measures, such as whether the central bank raises interest rates and adjusts the reserve requirement ratio. At the same time, the level of CPI also indirectly affects the changes in the capital market (such as the first market, the first market, the first market, the capital market, and the financial market).

The purpose of compiling the household consumption index is to understand the basic situation of changes in all parts of the country, analyze and study the impact of changes on the social economy and residents' lives, meet the needs of formulating policies and plans at all levels, and carry out macroeconomic regulation and control, as well as providing reference and basis for national economic accounting.

The Consumer Price Index (CPI), combined with the Employment Situation Report (NFP), is another popular economic indicator that is carefully studied in the financial markets, because inflation affects everyone, it determines how much consumers spend on goods and services, it affects the cost of doing business, greatly undermines the investment of individuals or businesses, and affects the quality of life of retirees. Moreover, the outlook for inflation is helpful for the establishment of labor contracts and the formulation of fiscal policies.

CPI is a statistical indicator that is generally impossible for a single person to complete.

I can only give a brief explanation of the principle here.

Set a base number first, and the base number of 2010 used now will be adjusted once every five years.

If apples were 3 yuan per catty in 2010, and now the market is the first yuan, then the market is the first to be. Let's just say that Apple's CPI in this market is 7% (.

However, the published CPI is far more complicated than that. He first selects a certain sample of commodities, and according to a certain proportion, such as food (proportion, housing proportion (, clothing, medicine, services and other items), and then uses the weighted average of them in a period of time as the sample base, and then counts.

1. CPI is the abbreviation of Consumer Price Index. The Household Consumption Index is a macroeconomic indicator that reflects the changes in the level of consumer goods and services purchased by households. It is a relative number that measures the change of the **level of a group of representative consumer goods and services over time in a specific period of time, and is used to reflect the change of the **level of consumer goods and services purchased by households.

2. Calculation formula: CPI = (the value of a group of fixed commodities calculated according to the current period ** divided by the value of a group of fixed commodities calculated according to the base period**) 100%.

3. CPI means how much more it costs to buy a representative group of commodities today than at a certain time in the past, for example, if in 1995, the cost of buying a group of commodities per month for an ordinary household in a country was 1,000 yuan, and the cost of buying this group of commodities in 2000 was 1,100 yuan, then: taking 1995 as the base period, CPI 1995 = (1000 1000)*100%= 100%, CPI 2000=(1100 1000)*100%=110%

Inflation rate in 2000 = ((CPI 2000- CPI 1995) CPI 1995) * 100% = 10%.

Further information: 1. The National Household Consumption** Index (CPI) covers eight categories and 262 basic categories of goods and services** for the daily consumption of urban and rural residents across the country, including food, tobacco, alcohol and supplies, clothing, household equipment, supplies and maintenance services, medical care and personal goods, transportation and communications, entertainment, education, cultural goods and services, and housing. The data were surveyed in 500 cities and counties in 31 provinces (autonomous regions and municipalities) and 10,000 households**, including grocery stores, department stores, supermarkets, convenience stores, specialty markets, specialty stores, shopping malls, farmers' markets and service consumption units.

2. Statistical scope: The National Household Consumption Index (CPI) covers 8 categories and 262 basic categories of goods and services consumed by urban and rural residents across the country, including food, tobacco and alcohol, clothing, housing, daily necessities and services, transportation and communications, education, culture and entertainment, medical care, and other goods and services.

3. Main impact: CPI is a lagging data, but it is often an important reference indicator for market economic activities and monetary policy. CPI stability, full employment, and GDP growth are often the most important socio-economic goals.

However, judging from the reality of China, the stability and importance of the CPI are not as developed countries believe"There is a certain authority, and the economic activity of the market will be adjusted according to the changes in the CPI"。

Calculation formula:

CPI = (value of a group of fixed commodities calculated by the current period ** Value of a group of fixed commodities calculated by the base period **) 100%.The fixed weights are calculated according to the weighted arithmetic mean formula, i.e., k'= kw w, the fixed weight is w, where k of the numerator in the formula is the individual index of various sales volumes.

For example, if in 1995, the average household in a country spent 800 yuan per month on a group of goods, and in 2000 it cost 1,000 yuan to buy this group of goods, then the country's consumption index in 2000 was.

Taking 1995 as the base period) CPI = 1000 800 100% = 125%, that is to say, ** (125-100) = 25%.
