Understanding Inflation: What Is It and Why Should You Care?
CPI and Core Inflation
The Consumer Price Index (CPI) is a measure of the cost of living for the typical person. It includes the prices of a wide range of goods and services, from food and housing to transportation and healthcare. Core CPI, on the other hand, excludes food and energy prices, which can be volatile and distort the overall picture of inflation.
Measuring Core Inflation
Core inflation is measured by both the CPI and the core Personal Consumption Expenditures (PCE) index. The PCE index is another measure of inflation that is calculated by the Federal Reserve. It represents the prices of goods and services purchased by consumers.
Headline Inflation vs. Core Inflation
Headline inflation refers to the change in value of all goods in the CPI basket. Core inflation, on the other hand, excludes food and fuel items from headline inflation. This is because food and fuel prices can be volatile and can provide a distorted picture of the underlying trend in inflation.
Why You Should Care
Understanding inflation is crucial for financial planning and decision-making. Inflation can erode the value of your savings and investments, and it can also impact your purchasing power. By tracking inflation and understanding the difference between headline inflation and core inflation, you can make more informed decisions about your finances.
Example: April 2021 CPI Data
In April 2021, the headline CPI increased by 4.2%, while the core CPI (excluding food and energy) rose by 3%. This suggests that overall inflation is being driven by increases in food and energy prices, rather than by a broader increase in prices across the economy.
