Achieving inflation that’s not too hot, not too cold, but just right is needed to drive spending among businesses and consumers, and thereby create a baseline of economic growth. While the market basket used to calculate CPI measures the prices of items, it does not measure how quality can change over time. While the cost of many different items used in everyday life has gone up, their quality may have also risen. Prices that make up CPI inflation calculations come from the BLS’ Consumer Expenditure Surveys, which assess what real Americans are buying. Approximately 24,000 consumers from around the U.S. are surveyed by the BLS every quarter, and another 12,000 consumers maintain annual diaries of their purchases. The makeup of the basket of goods and services changes gradually over time, following the survived buying habits of consumers, but overall, CPI inflation is calculated from a pretty fixed set of goods and services.
The government periodically adjusts these weights to correspond with the changing behaviors of consumers. The Consumer Price Index is an important economic indicator that is widely used to measure inflation and inform decision-making by policymakers, businesses, investors, and consumers. This information is used by policymakers, businesses, and investors to make informed decisions about economic policy, pricing, and investment strategies. The basket of goods and services includes food, housing, transportation, healthcare, and entertainment.
An increase in the value of the index offers a quantitative measure of inflation, or the decline of the dollar’s purchasing power over time. As a result, the market basket that is used to calculate this key economic indicator consists of a wide range of costs that consumers incur on a regular basis. The CPI uses the average price changes for an established basket of goods and services to demonstrate price trends within the economy.
CPI-W is used to adjust Social Security payments as well as other federal benefits and pensions for changes in the cost of living. It also shifts federal income tax brackets to ensure taxpayers aren’t subjected to a higher marginal rate as a result of inflation. “The chained CPI-U provides a more accurate estimate of changes in the cost of living from one month to the next by using market baskets from both months, thus ‘chaining’ the two months together,” the post clarifies. The CPI has a wide range of uses, including informing economic policy-making, identifying investment opportunities and risks, and helping businesses make pricing and business strategy decisions. Inflation can significantly affect an economy, as it can impact the stability of financial markets by influencing the purchasing power of consumers and the profitability of businesses. The Consumer Price Index holds significant importance as an economic indicator due to its ability to measure inflation and provide valuable information to policymakers, businesses, and investors.

- When inflation rises beyond a comfortable level (2%, as a rule of thumb), the Federal Reserve may take steps such as raising interest rates to slow the economy.
- A handful of types of CPI are calculated in order to provide a more comprehensive level of data on inflation.
- However, the CPI also has some limitations, such as its potential to not reflect individual circumstances or preferences, and to not accurately capture the impact of technological advances or changes in quality.
It measures the average change in prices paid by consumers over a period of time for a basket of goods and services. It is among the most common measures of inflation, indicating the health and direction of the economy. It also serves in other capacities, notably to help make adjustments to certain income payments, such as Social Security and pensions for federal civil service retirees. The Consumer Price Index (CPI) is a measure of changes in product costs over a specific time period, and it is used as both an indicator of the cost of living and economic growth.

“The BLS reports index weights for dozens of categories, subcategories and specific items in the CPI’s basket of goods and services,” noted an article published on the website of the Pew Research Center. “The biggest category by far is shelter, which accounts for nearly a third of the index,” it emphasized. Interestingly enough, the CPI also accounts for something called lodging away from home, for example stays in hotel rooms. Overall, the CPI is a valuable tool for understanding the economy and making informed decisions, but it should be used together with other economic indicators and contextual information.

The Federal Reserve considers Core PCE to be its most important measure of inflation in the U.S.—although it also considers other inflation data when setting monetary policy. In general, the Federal Reserve aims to keep inflation (as calculated by Core PCE) at about 2%, though it has said it will let this rate run higher short term to encourage recovery from Covid-19-related economic damage. The CPI also includes substitution bias, which means it can overstate how much the cost of living has changed. For example, if the CPI captures a large increase in the price of an item, it doesn’t take into account people substituting that item for a cheaper one. Not taking this into account wrongly assumes that people continue to buy the more expensive item and experience a higher inflation rate than what they’re actually enduring.
Purchasing power
The Consumer Price Index (CPI) measures the monthly change in prices paid by U.S. consumers. The Bureau of Labor Statistics (BLS) calculates the CPI as a weighted average of prices for a basket of goods and services representative of aggregate U.S. consumer spending. The return an investor receives on an investment or portfolio is the nominal return. By using CPI inflation rates, this return can be adjusted to take inflation into account, yielding the real rate of return. An investor’s required return should always be the real rate of return to account for the negative impact of inflation on investment values. The CPI is important to investors for many reasons, as the rate of inflation can have an impact across financial markets.
Similarly, when interest rates are adjusted for inflation, it can help to prevent economic instability by maintaining the real value of savings and investments. The Consumer Price Index is an important economic indicator because it measures inflation, which is the rate at which the level of prices for goods and services is rising. The Bureau of Labor Statistics (BLS) calculates CPI inflation by gathering spending data from tens of thousands of regular consumers around the U.S.
How Is the Consumer Price Index (CPI) Used?
In addition to measuring inflation, the CPI is used to adjust economic variables for inflation. For example, wages, taxes, and interest rates are often adjusted using the CPI to maintain their real value over time. The CPI is considered by many to be a benchmark indicator for inflation in the U.S. economy. CPI gauges the overall health of the U.S. economy, and it’s the most popular economic indicator that people use to demonstrate how much prices are rising or falling. It’s important to note that there is also seasonally adjusted data included in the CPI.
The Bureau of Labor Statistics used the surveys to select more than 200 categories of goods and services to monitor. The CPI increases or decreases based on average price movements inside the market basket. The BEA’s personal consumption expenditures price index also calculates a core PCE measure, like CPI, that strips out volatile food and energy prices.

For example, the CPI only measures inflation for U.S. urban populations, thus leaving out the inflation experience of people living in rural areas. It also doesn’t include estimates of how different subgroups are experiencing inflation, such as the elderly or those living in poverty. By creating blanket assumptions of how people across varying demographics are experiencing inflation, monetary policy can’t fully capture or reach the needs of these different subgroups. The CPI report includes a number of tables that break down how various goods and services increased over the past month, as well as the past 12 months. Everyday items, such as meat, vegetables, cleaning supplies and even clothing are tracked. Mortgage rates (and other forms of long-term debt) are often impacted by rates set by government agencies.
