Inflation steadily erodes the purchasing power of money — the same amount buys less over time. This calculator quantifies that erosion: it shows how much value a sum loses over a period at a given inflation rate, and what an amount today would need to be in the future to buy the same things.
Understanding this is essential for any long-term financial planning, because a figure that seems adequate now may fall well short decades later. It also reframes “safe” savings: money sitting at a return below inflation is quietly losing real value even as the nominal balance holds steady.
It runs in your browser, so your figures stay private. It uses the constant inflation rate you provide; real inflation varies year to year, so treat the result as an illustration of the mechanism and a planning estimate.
