R$100.00 in December 1979
R$100,260,633,484,162.97 (≈ R$100.26 trillion) in May 2026

The cumulative inflation rate in Brazil between December 1979 and May 2026 was 100.26 trillion percent, meaning that overall prices were 1 trillion times higher than they were in December 1979. In other words, the purchasing power of R$100 in Dec 1979 was equivalent to R$100.26 trillion in May 2026. The average annual inflation rate over this period was 5.09%.

Inflation timeline in Brazil (Dec 1979 - May 2026)

The chart below shows how the value of R$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 Brazilian reals 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:

Avg. Monthly inflation from 1979-12 to 2026-05 5.09%
CPI 1979-12 1.77e-10
CPI 2026-05 177.26

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 months, we can use the following formula:

Valuet =Value0 ×
CPIt/CPI0

To obtain the values equivalent in buying power between December 1979 and May 2026, use the corresponding CPI values:

ValueMay 2026
=ValueDec 1979 ×
CPIMay 2026/CPIDec 1979
=R$ 100 ×
177.26/1.77e-10
R$100.26T

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 months)

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 R$100 worth today. There are 557 months between December 1979 and May 2026 and the average inflation rate was 5.0863%. Therefore, we can resolve the formula like this:

ValueMay 2026
=PV × (1 + i)n
=R$100 × (1 + 0.050863)557
R$100.26T
