Rp100 in January 1968
Rp24,054.72 in December 2025

The cumulative inflation rate in Indonesia between January 1968 and December 2025 was 23,954.72%, meaning that overall prices were 240.5 times higher than they were in January 1968. In other words, the purchasing power of Rp100 in Jan 1968 was equivalent to Rp24,054.72 in Dec 2025. The average annual inflation rate over this period was 0.79%.

Inflation timeline in Indonesia (Jan 1968 - Dec 2025)

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.

The following table contains relevant indicators:

Indicator Value
Cumulative inflation from 1968-01 to 2025-12 23,954.72%
Avg. Monthly inflation from 1968-01 to 2025-12 0.79%
CPI 1968-01 0.56
CPI 2025-12 135.27

How to calculate the time value of money with inflation data?

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.

Using the CPI formula

When we have both the start and end months, we can use the following formula:

Valuet =Value0 ×
CPIt/CPI0

To obtain the values equivalent in buying power between January 1968 and December 2025, use the corresponding CPI values:

ValueDec 2025
=ValueJan 1968 ×
CPIDec 2025/CPIJan 1968
=Rp 100 ×
135.27/0.56
Rp24,054.72

Alternative: Using the compound interest formula

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:

  • FV: Future Value
  • PV: Present Value
  • i: Interest rate (inflation)
  • n: Number of times the interest is compounded (i.e. # of months)

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 695 months between January 1968 and December 2025 and the average inflation rate was 0.792%. Therefore, we can resolve the formula like this:

ValueDec 2025
=PV × (1 + i)n
=Rp100 × (1 + 0.00792)695
Rp24,054.72
