€100 in 1955

€12,079.58 in 2024

The cumulative inflation rate in Portugal between 1955 and 2024 was 11,979.58%, meaning that overall prices were 120.8 times higher than they were in 1955. In other words, the purchasing power of €100 in 1955 was equivalent to €12,079.58 in 2024. The average annual inflation rate over this period was 7.2%.

Inflation timeline in Portugal (1955 - 2024)

The chart below shows how the value of €100 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 euro (Portugal) 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:

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 1955 and 2024, use the corresponding CPI values:

Value₂₀₂₄

=Value₁₉₅₅ ×

CPI₂₀₂₄/CPI₁₉₅₅

=€ 100 ×

120.55/1

≈€12,079.58

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 €100 worth today. There are 69 years between 1955 and 2024 and the average inflation rate was 7.195%. Therefore, we can resolve the formula like this:

Value₂₀₂₄

=PV × (1 + i)ⁿ

=€100 × (1 + 0.07195)⁶⁹
