The Consumer Price Index (CPI) basically measures inflation. The CPI takes a basket of goods and sees how much each of those goods costs. A change in the price of this basket of goods produces a change in the CPI. The CPI is representative of the prices of all goods in the economy for the United States and measures the changes in these prices over time.
The GDP Deflator uses the GDP calculation to work out inflation while CPI uses a basket of goods that are compared over time to work out the increase in prices
The PPI is based on the cost of a basket typically purchased by producers, while the CPI is based on the cost of a basket typically purchased by consumers.
The government uses a market basket of goods to measure inflation. The market basket of goods is a collection of items that are representative of the overall economy. The items in the market basket are weighted based on their importance in the economy. The weights are updated periodically to ensure that they accurately reflect the current economy.
Ex: CPI in 2000 is 3,500 CPI in 2001 is 4,500 What's the inflation rate? 4500 - 3500 = 1000 1000/3500 = .2857.... .2857 * 100 = 28.57 is the INFLATION RATE In generality: CPI (Target year 1) - CPI (Target year 2) / CPI (Target Year 2) For this year's inflation since last year: CPI (This Year) - CPI (Last year) / CPI (This year) Source: easycalculation.com
Criticisms of the CPI All the criticisms of the CPI arise from the fact that it is a fixed weight basket. The three main criticisms are given below: 1. The CPI suffers from a substitution bias. 2. The CPI does not include new products. 3. The CPI does not include quality changes.

The Consumer Price Index (CPI) measures the average change over time in prices paid by urban consumers for a market basket of goods and services. It is used as an indicator of inflation and is calculated by comparing the price of the basket of goods and services in the current period to a base period. The CPI is widely used to adjust income and payments, such as social security benefits, for changes in purchasing power.
consumer price index = market basket of desired year market basket of base year × 100 {\displaystyle {\text{consumer price index}}={\frac {\text{market basket of desired year}}{\text{market basket of base year}}}\times {\text{100}}} or CPI 2 CPI 1 = price 2 price 1 {\displaystyle {\frac {{\text{CPI}}{2}}{{\text{CPI}}{1}}}={\frac {{\text{price}}{2}}{{\text{price}}{1}}}} Where 1 is usually the comparison year and CPI1 is usually an index of 100.Alternatively
a measure that examines the weighted average of prices of a basket of consumer goods and services
To answer this question you will want to reference the Bureau of Labor Statistics Website: www.bls.gov. From there you can get information about each year's Consumer Price Index (CPI). The CPI takes a "basket" of goods and compares the prices of these goods month to month and year to year. The CPI is based on how much of this basket a dollar can buy. I have used the Annual Average CPI for both years from the A;ll Urban Consumers (Current Series) Data Table. The equation to solve this problem is as follows: 1989 1$ (CPI 2008/CPI 1989) = 1989 1$ stated in 2008$ So: 1(215.303/124.0) = $1.74 To state this in words: $1.00 in 1989 would buy the same amount of goods as $1.74 would buy in 2008.

The Consumer Price Index (CPI) is calculated by the U.S. Bureau of Labor Statistics (BLS). The BLS collects price data each month to track changes in prices of a representative basket of goods and services commonly purchased by consumers.

A consumer price index (CPI) is a measure estimating the average price of consumer goods and services purchased by households. A consumer price index measures a price change for a constant market basket of goods and services from one period to the next within the same area (city, region, or nation). It is a price index determined by measuring the price of a standard group of goods meant to represent the typical market basket of a typical urban consumer. Related, but different, terms are the United Kingdom's CPI, RPI, and RPIX. It is one of several price indices calculated by most national statistical agencies. The percent change in the CPI is a measure estimating inflation. The CPI can be used to index (i.e., adjust for the effect of inflation on the real value of money: the medium of exchange) wages, salaries, pensions, and regulated or contracted prices. The CPI is, along with the population census and the National Income and Product Accounts, one of the most closely watched national economic statistics.
