The cumulative inflation rate in Indonesia between 1986 and today has been 1,806.02%, meaning that prices are 19.1 times higher than they were in 1986. In practical terms, the purchasing power of Rp100 in 1986 is equivalent to Rp1,906.02 in today's rupiah. The average annual inflation rate over this period has been 7.85%.
The chart below shows how the value of Rp100 changes over time when adjusted for inflation, based on Consumer Price Index (CPI) data. All values are equivalent in terms of purchasing power, indicating how much money would be needed each year to buy the same goods or services.
All calculations are performed in Indonesian rupiah with six-decimal precision, though displayed values are rounded to two decimals for readability. Inflation figures are sourced from official government and international reports released monthly. To convert historical amounts into today's rupiah, we use the most recent CPI data available and extrapolate it to estimate the CPI for today.
The following table contains relevant indicators:
| Indicator | Value |
|---|---|
| Cumulative inflation 1986-2024 | 1,749.51% |
| Cumulative inflation 1986-today | 1,806.02% |
| Avg. Annual inflation 1986-2024 | 7.98% |
| CPI 1986 | 7.06 |
| CPI 2024 | 130.57 |
| CPI 2025-10 (latest official data) | 134.19 |
| CPI today | 134.56 |
There are several ways to calculate the time value of money. Depending on the data available, results can be obtained by using the Consumer Price Index (CPI) formula or the compound interest formula.
When we have both the start and end years, we can use the following formula:
To obtain the values equivalent in buying power between 1986 and 2024, use the corresponding CPI values:
To obtain the equivalent value today (present value), plug in the CPI for today, which is estimated as 134.56:
Given that money changes with time as a result of an inflation rate that acts as compound interest, we can use the following formula: FV = PV × (1 + i)n, where:
In this case, the future value represents the final amount obtained after applying the inflation rate to our initial value. In other words, it indicates how much are Rp100 worth today. There are 38 years between 1986 and 2024 and the average inflation rate was 7.9801%. Therefore, we can resolve the formula like this:
