There are several ways to calculate the time value of money. Depending on the data available, results can be obtained by using the compound interest formula or the Consumer Price Index (CPI) formula.

Given that money changes with time as a result of an inflation rate that acts as a compound interest, the following formula can be used: **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 years)

In this case, the future value represents the final amount obtained after applying the inflation rate to our initial value. In other words, the future value is the amount in 2021 that equals Rp100 in 1969 in terms of purchasing power. There are 52 years between 1969 and 2021 and the average inflation rate was 10.2048%. Therefore, we can resolve the formula like this:

**FV = PV (1 + i) ^{n} = Rp100 * (1 + 0.102048)^{52} = Rp15,646.656707 ≈ Rp15,646.66**

When the CPI for both start and end years is known, the following formula can be used:

Final value = Initial value *

CPI finalCPI initial

In this case, the CPI in 1969 was 0.75 and in 2021 was 117.32. Therefore,

Final value = Initial value *

CPI finalCPI initial

= Rp100 *
117.320.75

= Rp15,646.66
