Brazil Inflation Calculator

Adjust amounts by the right index, using the same math as the Central Bank.

The calculator adjusts an amount in Brazilian reais by the monthly change of IPCA, INPC or IGP-M, from July 1994 (the month of the Real Plan) to the latest published index. The math is the same as the Central Bank of Brazil Citizen Calculator: multiply (1 + change/100) for every month in the period, and the result is the adjustment factor. From January to December 2020, for example, IPCA accumulated 4.52%, so R$ 100.00 in January becomes R$ 104.52 in December. The three indexes measure different things. IPCA, from IBGE, tracks prices for households earning 1 to 40 minimum wages and is the inflation target index. INPC, also from IBGE, covers households earning 1 to 5 minimum wages, so food and transport weigh more. IGP-M, from FGV, blends wholesale, consumer and construction prices and swings much more, which is why it reached 23.14% in 2020 while IPCA stayed at 4.52%. Besides the adjusted amount, the tool shows cumulative inflation, the average per year, the purchasing power idle money lost, the three indexes side by side, a chart and the month-by-month table. The data comes straight from the Central Bank API and is refreshed on every site publication. The result is an economic estimate: court debts follow their own tables and terms, handled separately by the judicial monetary correction calculator.

Enter the amount, the period and the index.

1. Type the amount in reais and pick the index: IPCA for official inflation, INPC for a pay reference, IGP-M if your rental or financing contract names it.
2. Pick the start and end months, or tap a shortcut such as Since the Real Plan or Last 5 years. The result shows at once.
3. Read the adjusted amount, cumulative inflation, purchasing power and the comparison between indexes. Under More options, enter your current amount to see whether it kept up with inflation, or reverse the calculation to bring a present-day amount back in time.
