Inflation and Purchasing Power Calculator

This simulation uses your entered constant annual rate, not a historical CPI series or an updated national inflation figure. For actual historical comparisons consult official indices for the country and period. Currency changes only formatting; it neither chooses a rate nor converts currencies.

Equivalent amount = starting amount × (1 + inflation/100) raised to the number of years. With 100 and 10% over two years, 121 is needed, not 120. Keeping the same 100 gives purchasing power of 82.64 in starting-year money; cumulative inflation is 21%, but purchasing-power loss is 17.36% because their bases differ.

Years must be ordered and no more than 100 years apart. A negative rate represents deflation and can produce a purchasing-power gain. Personal inflation depends on your consumption basket; neither a national average nor a constant assumption describes every expense. Default rates are examples for exploring scenarios.

Currencies cover Venezuela, Mexico, Spain, Colombia, the United States, Argentina, Chile, Uruguay, Paraguay, Peru, Bolivia, Ecuador, Costa Rica, the Dominican Republic and Brazil. These are universal financial calculations without exchange conversion or automatic national tax or benefit rules. Defaults are examples; rates are assumptions, not current quotes or guarantees.
