Buying power of Rp8,000 in 1982

This chart shows a calculation of buying power equivalence for Rp8,000 in 1982 (price index tracking began in 1959).

For example, if you started with Rp8,000, you would need to end with Rp210,699.86 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When Rp8,000 is equivalent to Rp210,699.86 over time, that means that the "real value" of a single Indonesian ruphia decreases over time. In other words, a ruphia will pay for fewer items at the store.

This effect explains how inflation erodes the value of a ruphia over time. By calculating the value in 1982 dollars, the chart below shows how Rp8,000 is worth less over 44 years.

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