1. 1、 Two cases of tcpi calculation
1. The future project performance is completed according to the original budget BAC:
tcpi = (BAC – EV) / (BAC – AC)
if the management says: now the financial situation is tight, there is no extra money allocated to the project, so we must do things well with the money on hand! Then we need to know the remaining workload (bac-ev) and the remaining budget (bac-ac), namely (bac-ev) / (bac-ac)
2. The future project performance is completed according to the new EAC:
tcpi = (BAC – EV) / (EAC – AC)
if the management says: your earned value report is reasonable, the rest of the work should be done according to the new estimate. Then we need to see how much work is left (bac-ev), and then according to the new completion estimate, we need to see how much money is left (eac-ac), namely (bac-ev) / (eac-ac).

CPI = (the value of a group of fixed commodities at the current price divided by the value of a group of fixed commodities at the base price) × 100%

CPI indicates how much more it costs to buy a representative group of goods today than at a certain time in the past for the expenditure of ordinary families. For example, in 1995, the average family in a certain country paid 1000 yuan for purchasing a group of goods every month, while in 2000, the cost of purchasing this group of goods was 1100 yuan, Then:

take 1995 as the base period

CPI 1995 = (1000 / 1000) * 100% = 100%, CPI 2000 = (1100 / 1000) * 100% = 110%

the inflation rate in 2000 = ((CPI 2000-cpi 1995) / CPI 1995) * 100% = 10%

statistical method

provincial (District, city) investigation teams should select local cities, counties and price investigation points. At present, there are more than 550 cities and counties in China's survey area, with nearly 30000 price collection points, and nearly 4000 price collectors with professional training Engaged in price collection

the first step is to select the price survey points independently by the survey cities and counties

these cities and counties need to determine the shops, farmers' markets and service outlets (called survey points in statistical terms) for price survey. The methods for determining survey points are as follows: firstly, all survey outlets are queued from high to low with retail sales and business scale as the marks; Then, according to the required number of survey points, the equal distance sampling was carried out, and combined with the principle of considering both size and reasonable distribution

The second step is price collection

All provinces (autonomous regions and municipalities) have fixed price investigators and temporary investigators to collect prices according to unified regulations. After the investigation points are determined, the price investigators of all cities and counties shall collect, investigate and register the commodity or service prices of the selected shops, markets and service outlets within the specified time according to the "three fixed" principle, that is, direct price collection by fixed point, fixed time and fixed person

fixed point means to go to the selected survey points, namely fixed survey shops and farmers' markets, so as to ensure the stability and comparability of price data sources. Timing, that is, to collect prices on a fixed day and time, ensures the comparability of the prices in the base period and the reporting period, because the prices are collected at different times, so are the prices of commodities

this is the most obvious manifestation of fresh goods, such as fresh vegetables, which are usually higher in the morning when they first appear on the market, and lower in the evening when they close. Therefore, when concting price surveys, not only the number and date of each month should be consistent, but also the time of each survey should be relatively fixed

In order to avoid the error of price survey caused by the frequent changes of investigators and maintain the stability, continuity and comparability of price data, it is necessary to set up a fixed number of investigators in a certain period of time. At the same time, the computer management system of price collection points is often used as an auxiliary survey tool

There are also the following principles in the actual price collection: the price of the same specification must be comparable, that is, the proct nature is basically the same and can be compared; If the listing price of the commodity is inconsistent with the actual transaction price, the actual transaction price shall be investigated and collected; For commodities (such as fresh vegetables, fruits and other fresh food) closely related to residents' life and with frequent price changes, the price should be investigated at least once every five days

the prices of general commodities were investigated and collected 2-3 times a month. The third step is data reporting. The survey cities and counties will report the price data to the provincial (District, city) survey team through the network every month, and the survey team will report the data to the National Bureau of statistics within the specified time after audit

the basic function of CPI index

1, measuring inflation (deflation). CPI is an important index to measure inflation. Inflation is a general and sustained rise in the price level. The level of CPI can explain the severity of inflation in a certain level

(2) national economic accounting. In national accounts, various price indices are needed. For example, consumer price index (CPI), procer price index (PPI) and GDP deflator are used to calculate GDP, so as to eliminate the influence of price factors

3. Contract index adjustment. For example, in salary negotiation, because employees want the increase of salary (nominal) to be equal to or higher than CPI, they want nominal salary to be adjusted automatically with the increase of CPI. The timing of adjustment is usually after the occurrence of inflation, and the range is lower than the real inflation rate

4. Reflect the change of money purchasing power: money purchasing power refers to the quantity of consumer goods and services that can be purchased by unit currency. The consumer price index rises, while the purchasing power of money declines; On the contrary, it will rise. The reciprocal of the CPI is the money purchasing power index

5, reflecting the impact on the actual wages of employees: the increase of CPI means the decrease of real wages, and the decrease of CPI means the increase of real wages. Therefore, the CPI can be used to convert nominal wages into real wages

The impact of CPI on the stock market: Generally speaking, prices rise and stock prices rise; As prices fall, so do share prices

3. In economics, the inflation rate is: the rising speed of the average price level (subject to inflation). If the size of the balloon is the price level, the inflation rate is the inflation rate of the balloon. In other words, the rate of inflation is the rate of decline in the purchasing power of money
the inflation rate can be calculated by the growth rate of price index, which can be calculated by consumer price index (CPI), procer price index (PPI) and GNP converted price index respectively. The first one is often used, and its formula is as follows:
CPI = A1 (p1T / P10) + A2 (p2t / P20) +... + an (pnt / pN0) (Note: the number, t and N in the formula are subscripts, and P is the price of representative consumer goods, A is the weight)

calculation method:
① calculated by the change of price index: inflation rate (rate of price increase) = {(current price level - base price level) / base price level} (the rate of price increase is from low to high, with the base price level as the base)
note that the inflation rate is not the price index, that is, it is not the rate of price increase, It's the rate of increase in the price index< (2) the inflation rate (rate of price rise) = (the amount of money issued - the amount of money actually needed in circulation) / the amount of money actually needed in circulation × 100%

5. The Ministry of ecation of China recognizes the degree of Christchurch Polytechnic Institute of Technology (cpit) of Christchurch Polytechnic College of New Zealand

6. The calculation formula of CPI is CPI = (the value of a group of fixed commodities at the current price / the value of a group of fixed commodities at the base price) × 100%

What CPI tells us is how much more it costs to buy a representative group of goods today than at a certain time in the past. For example, in 1995, the average family in a country paid 800 yuan for a group of goods per month, while in 2000, it paid 1000 yuan for that group of goods, Then the consumer price index of the country in 2000 is (based on 1995) CPI = 1000 / 800 × 100% = 1.25, that is to say, it has increased by 25%. In daily life, we are more concerned about the inflation rate, which is defined as the percentage of price level change from one period to another. The formula is t = (p1-p0) / P0, where t is the inflation rate of period 1, P1 and P0 are the price levels of period 1 and 0 respectively. If the consumer price index introced above is used to measure the price level, then the inflation rate is the percentage change of the consumer price index in different periods. If the consumer price index of an economy 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 to say, the inflation rate is 12%, which shows that the price rises by 12%

when CPI is greater than or equal to 1, it indicates that the situation is favorable, while when CPI is less than 1, it indicates that the situation is unfavorable.

7. Consumer price index, abbreviated as CPI, is a statistical index reflecting the price changes of goods and services related to people's lives. It is usually used as an important indicator to observe the level of inflation. If the consumer price index rises too much, it indicates that inflation has become an unstable factor in the economy, and the central bank will have the risk of tightening monetary and fiscal policies, resulting in an uncertain economic outlook. Therefore, the index's excessive increase is often not welcomed by the market. For example, in the past 12 months, the consumer price index has risen by 2.3%, which means that the cost of living has risen by an average of 2.3% over 12 months ago. When the cost of living goes up, the value of your money goes down. The calculation formula of CPI is CPI = (the value of a group of fixed commodities at the current price) divided by (the value of a group of fixed commodities at the base price) multiplied by 100%. CPI tells people how much more it costs to buy a representative group of goods today than at a certain time in the past. For example, in 1995, the average family in a country paid 800 yuan for a group of goods a month, while in 2000, the cost of buying this group of goods was 1000 yuan, Then the consumer price index of the country in 2000 is (based on 1995) CPI = 1000 / 800 * 100 = 125, that is to say, it has increased by 25%. In daily life, we are more concerned about the inflation rate, which is defined as the percentage of price level change from one period to another. The formula is t = (p1-p0) / P0, where t is the inflation rate of period 1, P1 and P0 are the price levels of period 1 and 0 respectively. If the consumer price index introced above is used to measure the price level, then the inflation rate is the percentage change of the consumer price index in different periods. If the consumer price index of an economy 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 to say, the inflation rate is 12%, which shows that the price rises by 12%
PPI is an index to measure the change trend and degree of factory prices of instrial enterprises, It is not only an important economic index reflecting the price changes in the proction field in a certain period, but also an important basis for formulating relevant economic policies and national accounts. At present, there are more than 4000 kinds of PPI procts (including 9500 kinds of specification procts) in China, covering all 39 instrial categories, involving 186 types of investigation< br />

Generally speaking, CPI is the consumer price index. The general market economy countries think that CPI is within the acceptable range of 2-3%. Of course, it depends on other data

CPI (consumer price index) is one of the data used by the government to measure inflation

CPI is an index to measure the changes of the general price level in the market. The rise of the general price level means inflation, on the contrary, the decline of the general price level means deflation. The price index is just an index to measure the inflation or deflation in the economy. If the price index rises too much, it indicates that inflation has become a factor affecting social and economic instability. The central bank will have the policy of tightening monetary policy and the promulgation of relevant fiscal policies, which will have a certain impact on social and economic development. Therefore, the rise of the index will often have an impact on the economy. Price index is a kind of macroeconomic index that can express an economy. If the price index rises by 25% in half a year, that is to say, the cost is rising and the value of money is declining. Half a year ago, 100 yuan now can only buy 75 yuan of goods or consumption

extended data

consumer price index; The consumer price index (CPI) is an economic indicator of price changes that reflect the prices of procts and services related to people's lives. It is expressed in the form of percentage changes. It is one of the main indicators of inflation. Generally, inflation is defined as more than 3%, and more than 5% is a serious inflation. CPI is often an important reference index of market economic activities and government monetary policy

Stable CPI, full employment and GDP growth are often the most important social and economic goals. If the consumer price index rises too much, it indicates that inflation has become an unstable factor in the economy, and the country will have the risk of tightening monetary policy and fiscal policy, resulting in the uncertainty of the economic outlook. Therefore, the index's excessive increase is often not welcomed by the market. The available means include raising interest rate, tightening monetary policy, adopting Steady Fiscal Policy, increasing proction and stabilizing prices

calculation method

the consumer price index measures the average change over time, including the retail prices of a variety of (often hundreds of) goods and services. This variety of goods and services will be divided into several main categories. When calculating the consumer price index, each category has a weight to show its importance. These weights are determined by surveying thousands of families and indivials about the procts and services they buy. Weights are often revised to match reality

CPI is a fixed quantity price index, which can not reflect the improvement or decline of commodity quality, and does not consider new procts. If the CPI dects the statistics of food and energy which are easy to fluctuate, this data is called "core price change rate". When the core price change rate is less than 3%, the economic growth rate should be at a relatively low level

the composition of CPI in Chinese mainland includes food, tobacco and liquor, supplies, clothing, family equipment, health care, transportation and communication, entertainment and ecation culture, and eight major procts. The CPI has the highest weights in eight categories of procts. p>
