Understanding Inflation Rate
Inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Central banks attempt to limit inflation, and avoid deflation, in order to keep the economy running smoothly.
The inflation rate between two periods is calculated using the Consumer Price Index (CPI) for each period. The CPI is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.
The formula to calculate the inflation rate is:
Inflation Rate = [ (CPI in Final Year – CPI in Initial Year) / CPI in Initial Year ] * 100
A positive inflation rate indicates that prices have risen, while a negative rate (deflation) indicates that prices have fallen.
Example Calculation:
Let's say the CPI in 2020 was 250.5 and the CPI in 2023 was 265.2.
Inflation Rate = [ (265.2 – 250.5) / 250.5 ] * 100
Inflation Rate = [ 14.7 / 250.5 ] * 100
Inflation Rate = 0.05868 * 100
Inflation Rate = 5.87%
This means that, on average, prices have increased by approximately 5.87% between 2020 and 2023.
