What is Consumer Price Index (CPI)?
The Consumer Price Index (CPI) measures the average change in prices paid by households for selected goods and services over time. It is a primary tool to track inflation, showing how the cost of living changes for consumers. Competitive and school exams frequently test questions based on CPI due to its significance in the Indian economy.
Significance and Calculation of Consumer Price Index (CPI)
CPI is important because it reflects real-life expenses for families and individuals. It helps in adjusting salaries, pensions, and government policies. The CPI is calculated by comparing the cost of a fixed basket of goods and services in the current year to the cost in the base year.
Formula for CPI Calculation
CPI = (Cost of basket in current year / Cost of basket in base year) × 100. For example, if the basket cost is ₹1,200 in 2024, and ₹1,000 in 2012 (base year), then CPI = (1200/1000) × 100 = 120.
