Buying power of R$100 in 1981

This chart shows a calculation of buying power equivalence for R$100 in 1981 (price index tracking began in 1980).

For example, if you started with R$100, you would need to end with R$25,474,771,531,038.64 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When R$100 is equivalent to R$25,474,771,531,038.64 over time, that means that the "real value" of a single Brazilian real decreases over time. In other words, a real will pay for fewer items at the store.

This effect explains how inflation erodes the value of a real over time. By calculating the value in 1981 dollars, the chart below shows how R$100 is worth less over 40 years.

According to the World Bank, each of these BRL amounts below is equal in terms of what it could buy at the time:

How to Calculate Inflation Rate for R$100 since 1981

Our calculations use the following inflation rate formula to calculate the change in value between 1981 and today:

CPI today CPI in 1981
1981 BRL value
Today's value

Then plug in historical CPI values. The Brazilian CPI was 7e-10 in the year 1981 and 178.32340071727046 in 2021:


R$100 in 1981 has the same "purchasing power" or "buying power" as R$25,474,771,531,038.64 in 2021.

To get the total inflation rate for the 40 years between 1981 and 2021, we use the following formula:

CPI in 2021 - CPI in 1981CPI in 1981
Cumulative inflation rate (40 years)

Plugging in the values to this equation, we get:

178.32340071727046 - 7e-107e-10
