Buying power of Rp50,000,000 in 1984

This chart shows a calculation of buying power equivalence for Rp50,000,000 in 1984 (price index tracking began in 1959).

For example, if you started with Rp50,000,000, you would need to end with Rp994,780,811.18 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When Rp50,000,000 is equivalent to Rp994,780,811.18 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 1984 dollars, the chart below shows how Rp50,000,000 is worth less over 39 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:

This conversion table shows various other 1984 amounts in today's ruphias, based on the 1,889.56% change in prices:
