Inflation Calculator
At a constant inflation rate, future cost equals today's amount x (1 + rate) raised to the number of years.
Worked example
| Initial amount | $1,000 |
|---|---|
| Annual inflation rate | 3% |
| Number of years | 10 |
| Future Cost (Equivalent Value) | $1,343.92 |
| Purchasing Power Lost | $343.92 |
How it is calculated
Future cost = amount x (1 + inflation rate / 100)^years.
The second result is the difference between future cost and the original amount, that is, how much more the same goods would cost.
Assumptions and limits
- Assumes one constant inflation rate; real inflation changes every year.
- You enter the rate yourself; the tool does not load official price-index data.

FAQ
How do I calculate future cost with inflation?
Multiply today's price by (1 + inflation rate) for each year. $1,000 at 3% for 10 years becomes $1,343.92.
What does the second result show?
The extra amount needed to buy the same goods: $343.92 in the example.
What inflation rate should I use?
Use a long-run average for your currency or a recent official figure; the tool does not provide official data.
