Inflation Calculator Scenarios and Practical Examples

Ces scénarios illustrent l’impact d’un taux d’inflation annuel supposé et de la durée sur le pouvoir d’achat, les prix futurs et les objectifs d’épargne.

How Inflation Projections and Purchasing Power Work

Inflation represents the broad increase in prices and corresponding decline in the purchasing power of money over time. The HelloTools Inflation Calculator models these effects through two distinct, mathematically sound perspectives:

Equivalent Future Cost

Answers: “How many dollars will I need in the future to buy what costs $X today?” Calculated using compound growth: Cost = Amount × (1 + r)^t.

Future Purchasing Power

Answers: “What will a fixed nominal sum of $X buy in future years?” Calculated by discounting nominal money: Purchasing Power = Amount / (1 + r)^t.

Key Modeling Assumptions & Scope

All calculations assume a constant annual inflation rate compounded annually. Projections are mathematical estimates for educational planning; they do not predict future economic cycles, variable CPI fluctuations, taxes, or investment yields.
