Inflation Calculator
See how inflation changes value over time
Inflation gradually reduces what money can buy. Enter an amount, an assumed annual inflation rate, and a number of years to see how the cost of the same goods could rise — and what your money would be worth in today's terms.
See how an assumed inflation rate changes value over time. You enter the rate — no live data is used.

- Enter the number of years.
- Review the future cost and the real value of your original amount.
Why Use This Calculator?
- Seeing why long-term savings need to outpace inflation.
- Estimating what something will cost in the future.
- Understanding why a salary that doesn't rise loses ground over time.
Real-World Examples
$100 at 3% inflation for 10 years
The same goods could cost about $134 in 10 years, while $100 kept as cash would buy only about $74 of today's goods.
How it compounds
Future cost = today's amount × (1 + rate)^years. Real value works in reverse — divide by the same factor. Even a modest rate, repeated over decades, erodes buying power noticeably.
Frequently Asked Questions
Where does the inflation rate come from?
You enter it. Historical averages vary by country and decade; the calculator uses whatever rate you choose for projection.
Does this match official inflation?
Official indexes track a basket of goods and vary by region. This is a simple projection at a single rate, not a forecast of any official index.
Why does my money lose value?
Because prices rise over time, a fixed amount of cash buys less in the future than it does today.
Important Disclaimer
A hypothetical projection at a single assumed rate. Actual inflation varies and is not predicted here. Not financial advice.
