$0.25 in 1929 is equivalent in purchasing power to about $43.48 in 2329, an increase of $43.23 over 400 years. The dollar had an average inflation rate of 1.30% per year between 1929 and 2329, producing a cumulative price increase of 17,290.36%. The buying power of $0.25 in 1929 is predicted to be equivalent to $43.48 in 2329.
This calculation is based on future inflation assumption of 3.00% per year. Use the calculator on the left to change this prediction. Or, use the annual inflation rate calculator to view inflation in the past.
This chart shows a calculation of buying power equivalence for $0.25 in 1929 (price index tracking began in 1635).
For example, if you started with $0.25, you would need to end with $43.48 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
When $0.25 is equivalent to $43.48 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.
This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1929 dollars, the chart below shows how $0.25 is worth less over 400 years.
Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index(CPI), established in 1913. Price index data from 1774 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society. Price index data from 1634 to 1773 is from the American Antiquarian Society, using British pound equivalents.
