Purchasing Power Calculator

About this calculator

Purchasing power measures what a fixed sum of money can actually buy after inflation has chipped away at it over time. Even if the nominal number in your bank account stays the same, rising prices mean each unit of currency buys fewer goods and services each year — this calculator applies a compounding inflation rate to your starting amount to show its real, inflation-adjusted value at a future date.

This matters for anyone planning years or decades ahead: a retiree budgeting a fixed pension, a saver comparing today's salary offer to one made years ago, or an investor checking whether their portfolio is actually growing in real terms or just keeping pace with rising prices. Seeing the erosion in concrete terms — 'this $10,000 will feel like $X in 20 years' — makes the abstract concept of inflation tangible and easier to plan around.
