R$100 in 1980
R$57,033,900,000,000 in 2018
The inflation rate in Brazil between 1980 and 2018 was 57,033,899,999,900%, which translates into a total increase of R$57,033,899,999,900. This means that 100 reals in 1980 are equivalent to 57,033,900,000,000 reals in 2018. In other words, the purchasing power of R$100 in 1980 equals R$57,033,900,000,000 in 2018. The average annual inflation rate between these periods was 103.88%.
The following chart ilustrates the equivalence of brazilian reals throughout the years due to compound inflation and CPI changes. All values are equivalent in terms of purchashing 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 (BRL) and using 6 decimal digits. Results show only up to 2 decimal digits to favour readability.
The following table contains relevant indicators:
| Indicator | Value |
|---|---|
| Total Inflation (1980-2018) | 57,033,899,999,900% |
| Annual inflation avg. (1980-2018) | 103.88% |
| CPI 1980 | 0 |
| CPI 2018 | 114.07 |
| R$1 in 1980 | R$570,339,000,000 in 2018 |
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 in 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:
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 2018 that equals R$100 in 1980 in terms of purchasing power. There are 38 years between 1980 and 2018 and the average inflation rate was 103.8787%. Therefore, we can resolve the formula like this:
FV = PV (1 + i)n = R$100 * (1 + 1.038787)38 = R$57,033,900,000,000 ≈ R$57,033,900,000,000
When the CPI for both start and end years is known, the following formula can be used:
In this case, the CPI in 1980 was 0 and in 2018 was 114.07. Therefore,
