This chart shows a calculation of buying power equivalence for $1 in 1740 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $1.18 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.18 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 1740 dollars, the chart below shows how $1 is worth less over 5 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:
