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 years, we can use the following formula:

Value_t =Value₀ ×

CPI_t/CPI₀

To obtain the values equivalent in buying power between 1989 and 2024, use the corresponding CPI values:

Value₂₀₂₄

=Value₁₉₈₉ ×

CPI₂₀₂₄/CPI₁₉₈₉

=zł 100 ×

151.8/0.97

≈zł15,697.45

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 years)

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 zł100 worth today. There are 35 years between 1989 and 2024 and the average inflation rate was 15.5415%. Therefore, we can resolve the formula like this:

Value₂₀₂₄

=PV × (1 + i)ⁿ

=zł100 × (1 + 0.155415)³⁵
