One of the ways to track inflation and the overall health of the economy is to refer to the Consumer Price Index. The CPI is a way to compare the cost of many of the goods and services Americans consume daily.
There are also regional consumer-price measures and in fact, several versions of the CPI have been developed to track trends in prices.
The CPI is a set of statistical measures of prices that change over time including the movement of prices for common consumer goods and services. The indexes generally go up when the country has inflation and go down when it has deflation. For the U.S. CPI, there are different versions designed to capture price information from different communities.
Some CPI updates are released monthly, while others are issued less frequently. The CPI is used by the Federal Reserve to develop monetary policy, especially in terms of inflation.
As people age, their ability to control their own costs of living will tend to dwindle due to the rising price. While many of these changes can be mitigated by increasing the dollar amounts spent on those items, you might never outrun inflation.
Understanding how prices and inflation work and how they are tracked is necessary to make good judgments on where to spend your money and which purchases will last.
If you are wondering what the Consumer Price Index means for you and your long-term financial health, read on for further information about this important cost-of-living indicator.
How Does the CPI Work?
The Consumer Price Index is one of several different types of inflation rate indexes designed to measure how much money consumers have to spend to cover the cost of everyday goods and services. The index is an important part of the government’s job of controlling inflation and making sure prices for products don’t rise too quickly.
The CPI measures what prices have been rising or falling for the last several years, but does not measure how much money a person makes. You can learn more about wages in the article titled The Great Wage Debate.
The Federal Reserve is one part of the government that is responsible for checking to make sure that no one is overcharging a consumer for products and services.
How The CPI Is Established?
The CPI is a product of the government, through the Bureau of Labor Statistics, which is part of the government’s Department of Labor. The CPI is a widely used statistic used to measure price changes of various goods and services throughout the economy. The Bureau of Labor Statistics tracks more than 30 different price changes in the national economy and provides these prices on a quarterly basis.
The CPI is compiled in a way that tries to mirror the purchasing power of a family with a certain level of income. The theory is that prices will increase and/or decrease over time based on changes in the unemployment rate, real money supply, etc. Over time, the CPI attempts to track the costs of food, shelter, clothing, health care, etc. for a family of four that has an annual income between $30,000 and $50,000. The Bureau of Labor Statistics does not track any prices specifically for retirees.
The BLS makes some assumptions and uses an economic model to calculate the Consumer Price Index (CPI) for most items. Using this model assumes that the prices of a family of four will increase or decrease in one quarter based on the overall unemployment rate and in another quarter based on the monetary aggregate, which is the gross domestic product, the U.S. Money Stock, and the velocity of money.
The Bureau of Labor Statistics says “All Consumer Price Index data are compiled in the same manner. Each of these three categories of indexing principles is in place for all items measured by the CPI, except for rent.”
There are also six items that are excluded from the CPI. These are food at restaurants, restaurants, healthcare, fuel, public transport, and education. “These items are excluded from the CPI for cost-effectiveness reasons,” according to the Bureau of Labor Statistics, and because the changes “are not large enough or are otherwise not very meaningful”.
The BLS also attempts to correct any inflation that may occur in the prices of any items that are excluded in order to come closer to a fair measure of overall inflation. If you would like to learn more about the CPI, check out this resource box.
What are the key components of the CPI?
The CPI is one of many inflation indices used by the BLS, including the GDP (Gross Domestic Product), HCI (Homes/Housing Components Index), and TIPS (Treasury Inflation-Protected Securities). As a result of this multiple-indicator approach, the CPI is the most widely used measure of inflation in the United States, especially when comparing the same category of products (for example, comparing apples and watermelons).
Because the CPI is an average of a basket of goods and services, any rise in the price of a component of the index will reflect an increase in the price of the basket as a whole. To offset this effect in the calculation of the CPI, BLS researchers exclude energy in determining inflation. For this reason, energy prices cannot be assumed to be a reliable indicator of inflation.
How to calculate CPI?
The calculation of the CPI involves the same method of weighting and averaging used to compute the index. In other words, the CPI is computed as BLS researchers, using data collected by the Bureau of Labor Statistics, determine from the Consumer Expenditures Survey (CES) the expenditure on goods and services for all U.S. households and then divide them for the category being considered.
The expenditure for each industry is weighted based on the population served by the business and then the expenditures, as compared with the expenditure on the same industry in the preceding year, and then normalized to a U.S. average of 100 percent to produce the index. This calculation, in turn, produces the index that will be used to determine the average of all the prices of the foods purchased by households, which is then averaged with those from all the other categories.
The categories for all calculations in the CPI are the following. Each category is weighted equally.
The U.S. CPI data are collected monthly by the U.S. Department of Labor. The data are in the public domain.

What is the importance of the Consumer Price Index? How does the index affect consumers?
*Join in on the conversation below by telling us your thoughts.
The Consumer Price Index (CPI) is a monthly report authored by the U.S. Bureau of Labor Statistics. The CPI essentially shows how inflation changes from month to month; it is important because it keeps people informed about the state of the economy. The CPI affects consumers because what they pay for everyday items changes with inflation; it is also crucial for market analysts and investors because it lets them know if they can make wise decisions in the volatility of the current market.
As one of the most important data sources in the world, the Consumer Price Index (CPI) is a compilation of price changes over time that are statistically analyzed to show how prices change on a monthly basis. The CPI is reported by the U.S Bureau of Labor Statistics to show consumers the state of the economy. The index affects consumers by helping them make informed decisions on their spending habits as well on any investment that they might have made or are thinking of making.
As a way of adjusting dollar values The CPI is often used to adjust consumers’ income payments for example, Social Security to adjust income eligibility levels for government assistance and to automatically provide cost of living wage adjustments to millions of American workers.
The Consumer Price Index (CPI) is a measurement and analysis tool, it is used to: Calculate and measure inflation in countries. Set the price of the family basket. It can affect them since sometimes the prices of basic things can go up a lot and inflation occurs.
