About Inflation Calculator

Uses CPI (Consumer Price Index) data: INSEE for France (1960–2024) and BLS CPI-U for the United States (1960–2024). The data is embedded and does not require an internet connection. Purchasing power = original amount × (CPI later / CPI earlier). Inflation erodes savings held in cash over time.
