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 1977 and 2023, use the corresponding CPI values:
To obtain the equivalent value today (present value), plug in the CPI for today, which is estimated as 130.98:
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 46 years between 1977 and 2023 and the average inflation rate was 8.635%. Therefore, we can resolve the formula like this:
