Buying power of €100 in 1975

This chart shows a calculation of buying power equivalence for €100 in 1975 (price index tracking began in 1954).

For example, if you started with €100, you would need to end with €1,510.04 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When €100 is equivalent to €1,510.04 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 1975 dollars, the chart below shows how €100 is worth less over 51 years.

According to the OECD and the World Bank, each of these EUR amounts below is equal in terms of what it could buy at the time:

This conversion table shows various other 1975 amounts in today's euros, based on the 1,410.04% change in prices:
