Inflation calculator
Explore purchasing power under your own inflation assumption.
Formula
Future cost = amount × (1 + rate/100)^years; purchasing power = amount / (1 + rate/100)^years
Equivalent future cost ≈ (1,000)×(1+(3)÷100)^(10) · Future cash purchasing power today ≈ (1,000)÷(1+(3)÷100)^(10)
How to use
- Enter an amount in one currency.
- Choose an assumed annual inflation rate and years.
- Compare future equivalent cost with future purchasing power.
Examples
- 1,000 with 10% inflation for 2 years needs 1,210.
- With zero inflation, 500 keeps the same buying power.
Frequently asked questions
Is this historical CPI data?
No. The rate is your assumption; no live or historical price index is loaded.
What do the two results mean?
Future cost preserves today’s basket; purchasing power values the unchanged cash amount in today’s prices.
Can I model falling prices?
Yes. Enter a negative rate; the tool accepts down to −50% annually.
