The inflation rate in Indonesia between 2009 and today has been 74.7%, which translates into a total increase of Rp74.7. This means that 100 rupiahs in 2009 are equivalent to 174.7 rupiahs in 2022. In other words, the purchasing power of Rp100 in 2009 equals Rp174.7 today. The average annual inflation rate between these periods has been 4.38%.
The following chart depicts the equivalence of Rp100 due to compound inflation and CPI changes. All values are equivalent in terms of purchasing power, which means that for each year the same goods or services could be bought with the indicated amount of money.
All calculations are performed in the local currency (IDR) and using 6 decimal digits. Results show only up to 2 decimal digits to favour readability. Inflation data is provided by governments and international institutions on a monthly basis. Today's values were extrapolated from the latest 12-month rolling average official data.
The following table contains relevant indicators:
|Cumulative inflation 2009-2021||64.52%|
|Cumulative inflation 2009-today||74.7%|
|Avg. Annual inflation 2009-2021||4.24%|
|CPI 2022-10 (latest official data)||125.17|
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 2009 and 2021, use the corresponding CPI values:
To obtain the equivalent value today (present value), plug in the CPI for today, which is estimated as 125.6:
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 12 years between 2009 and 2021 and the average inflation rate was 4.2361%. Therefore, we can resolve the formula like this:
