Buying power of $100 in 2050
This chart shows a calculation of buying power equivalence for $100 in 2018 (price index tracking began in 1635).
For example, if you started with $100, you would need to end with $266.52 in order to "adjust" for inflation (sometimes refered to as "beating inflation").
Future inflation is estimated at 3.00%.When $100 is equivalent to $266.52 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 2018 dollars, the chart below shows how $100 is worth less over 32 years.
