Buying power of €100 in 2015

This chart shows a calculation of buying power equivalence for €100 in 2015 (price index tracking began in 1954).

For example, if you started with €100, you would need to end with €124.86 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When €100 is equivalent to €124.86 over time, that means that the "real value" of a single Spanish euro decreases over time. In other words, a euro will pay for fewer items at the store.

This effect explains how inflation erodes the value of a euro over time. By calculating the value in 2015 dollars, the chart below shows how €100 is worth less over 9 years.
