How purchasing power shrinks
Real value of the amount at the end of each year.
How does inflation erode money?
Inflation means prices rise, so the same money buys less over time. The real value of a fixed amount falls by roughly the inflation rate each year — compounding, just like interest, but against you. That is why cash loses value and investing matters.
Real value formula
Real value = Amount / (1 + i)ⁿ i = annual inflation rate, n = number of years.

Frequently asked questions
How is the real value calculated?
Real value = amount / (1 + i)ⁿ, where i is the annual inflation rate and n the number of years. It shows what today's amount will actually buy in the future.
What is the difference between lost value and future cost?
Lost value is how much purchasing power your amount loses. Future cost is what the same goods will cost later — amount × (1 + i)ⁿ.
What inflation rate should I use?
Central banks often target around 2%, but it varies. Try a few rates to see the range — the full calculator compares several at once.
