Calculate inflation using CPI data or a custom inflation rate.
The Inflation Calculator uses historical Consumer Price Index (CPI) data from the United States to measure how the purchasing power of money changes over time.
Along with CPI-based calculations, forward and backward flat-rate inflation calculators are included for projections and historical analysis.
Inflation data in the U.S. is published by the Bureau of Labor Statistics through the Consumer Price Index (CPI), which tracks price changes in a basket of goods and services.
Inflation refers to a sustained rise in the general price level of goods and services, reducing the purchasing power of money over time.
Hyperinflation occurs when prices increase at an extremely rapid rate, often due to excessive money supply growth. Historical examples include Germany in the 1920s and Brazil in the 1980s.
Deflation is a general decrease in prices. While it may seem beneficial, it discourages spending and can slow economic growth.
Inflation impacts idle cash the most. To preserve purchasing power, people often invest in assets that historically outpace inflation, such as stocks, real estate, commodities, and inflation-protected bonds.
The calculator provides estimates based on historical CPI data and user-defined rates. Actual inflation may vary.

Yes. Inflation reduces purchasing power, which is why idle cash loses value over time.
Diversified investments such as stocks, real estate, commodities, and TIPS are commonly used as inflation hedges.
