This chart shows a calculation of buying power equivalence for $1 in 1815 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $17.81 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $17.81 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 1815 dollars, the chart below shows how $1 is worth less over 206 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:

Politics and news often influence economic performance. Here's what was happening at the time:

- Napoleon leaves Elba in order to reconnect with his supporters in France.
- Napoleon returns to Paris and begins his 100-day rule until his defeat in the Battle of Waterloo.
- The Holy Alliance is signed by Russia, Prussia and Austria
- Napoleon Bonaparte arrives on the island of Saint Hellena to begin his exile

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
