Understanding CPI & Inflation

The Consumer Price Index (CPI) is a macroeconomic metric that tracks the average price change over time for a fixed basket of goods and services. Cumulative Inflation represents the total percentage growth of this index across a specific time frame. Monitoring these shifts exposes the velocity of monetary depreciation. As prices rise, the domestic currency reduces its purchasing power, meaning more nominal capital is required to acquire the exact same volume of products.

Cumulative Inflation = (CPI_f / CPI_i) − 1
