What is the Difference Between Wholesale Price Index (WPI) and Consumer Price Index (CPI)?
🆚 Go to Comparative Table 🆚The main difference between the Wholesale Price Index (WPI) and the Consumer Price Index (CPI) lies in the basket of goods they measure and the stage of transactions they focus on. Here are the key differences between WPI and CPI:
- Measurement: WPI measures the average change in the price of goods sold in wholesale markets, while CPI measures the average change in the price of goods and services purchased by households.
- Focus: WPI focuses on the prices of goods traded between businesses, while CPI focuses on the prices of goods purchased by consumers.
- Stage of Transaction: WPI measures the initial or first stage of a transaction, as it tracks the change in commodity prices at selected stages before reaching consumers. In contrast, CPI measures the final or last stage of a transaction, as it calculates price changes of goods and services sold directly to consumers.
- Goods vs. Goods and Services: WPI covers only goods, while CPI covers both goods and services.
- Reference Period: WPI uses the financial year as a reference, while CPI uses the calendar year as a reference.
In summary, WPI and CPI are both measures of inflation, but they differ in the basket of goods they measure, the stage of transactions they focus on, and the entities involved in the transactions. While WPI tracks changes in wholesale-level prices, CPI measures retail-level price fluctuations of goods and services from the consumer's perspective.
Comparative Table: Wholesale Price Index (WPI) vs Consumer Price Index (CPI)
Wholesale Price Index (WPI) and Consumer Price Index (CPI) are both measures of inflation used by economists and policymakers to monitor economic changes. However, they differ in several aspects. Here is a comparison table highlighting the differences between WPI and CPI:
Feature | Wholesale Price Index (WPI) | Consumer Price Index (CPI) |
---|---|---|
Meaning | Measures the average change in price in the sale of goods in bulk quantity by the wholesaler. | Measures the change in the price in the sale of goods or services in retail or directly to the consumer. |
Focus Area | Measures inflation at the wholesale level, tracking changes in wholesale-level prices of goods. | Measures inflation at the retail level, tracking changes in retail-level prices of goods and services. |
Coverage | Covers goods only. | Covers both goods and services. |
Published By | Office of Economic Advisor, Ministry of Commerce and Industry. | Central Statistics Office, Ministry of Statistics and Programme Implementation. |
Measurement of Inflation | Measures inflation in the first stage. | Measures inflation in the final stage. |
Prices Bear By | Prices are borne by the manufacturer and wholesalers. | Prices are borne by the consumer. |
Reference Period | Uses the financial year as a reference. | Uses the calendar year as a reference. |
In summary, WPI measures the average change in the price of goods sold in bulk by manufacturers and wholesalers, while CPI measures the change in the price of goods and services sold directly to consumers at retail levels. Both indices are used to monitor inflation and economic changes, but they differ in their focus areas, coverage, and measurement methods.
