Why purchasing power matters
Inflation is the slow erosion of what money can buy. A sum that feels comfortable today will stretch less far in the future, even though the number on the banknote is unchanged. This calculator shows that erosion two ways: the future purchasing power of an amount you hold today, and the future cost of something that has today's price.
The lesson for investors is direct: a return that does not at least keep pace with inflation is a loss in real terms, however positive it looks on paper. This is why money left idle quietly shrinks, and why both equities and, for some, crypto are held in part as attempts to outrun inflation over time. The inflation rate here is an assumption you choose — real rates vary year to year — so use it to explore scenarios rather than to predict a precise future.
