The inflation rate measures the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. When the inflation rate is high, each unit of currency buys fewer goods and services, which can impact everyday life significantly.
Inflation is calculated as the percentage change in a price index, like the Consumer Price Index (CPI), over a certain period. The formula is:
- Inflation Rate = [(CPI in Current Year - CPI in Previous Year) / CPI in Previous Year] x 100
When inflation is high, it might erode savings, increase the cost of living, and lead to uncertainty in economic planning. This is where its impact on the misery index becomes evident. If both the unemployment rate and inflation rate are high, this indicates that people are not only struggling to find work but are also burdened by rising prices.
Keeping inflation at a manageable level is a goal for many central banks, as moderate and stable inflation is conducive to economic growth. Understanding and assessing inflation is therefore essential for both individuals and policymakers.
