  1. Enter an initial amount in Argentine pesos (ARS) in the “Monto Inicial” field.
  2. Select the start month and year — the period from which you want to measure inflation.
  3. The end month and year default to the latest available data. Adjust if needed.
  4. Results update automatically:
    • Monto Final — the inflation-adjusted equivalent amount
    • Total — total inflation percentage over the period
    • Promedio — average monthly inflation rate
    • Anual — annualized inflation rate
Data comes from INDEC (Argentina’s official statistics bureau) via ArgentinaDatos. Coverage begins in January 2017.
