What is inflation?

Inflation refers to the general increase in prices of goods and services over time, resulting in a decrease in the purchasing power of money. It’s essentially the decline in the real value of money, leading to higher prices for everyday items.

How is inflation calculated?

Inflation is typically calculated using the Consumer Price Index (CPI), which measures the average change in prices paid by consumers for a basket of goods and services over time. The formula for calculating inflation rate is:

Inflation Rate = [(Current CPI – Previous CPI) / Previous CPI] * 100%

Example: Suppose the CPI for January is 250 and the CPI for December is 260.
Using the formula:
Inflation Rate = [(260 – 250) / 250] * 100%
Inflation Rate = (10 / 250) * 100%
Inflation Rate = 0.04 * 100%
Inflation Rate = 4%
