FAQ
- Can the annual inflation rate be negative?
- Yes. A negative value represents a deflation assumption, and the same formula is applied.
- Does this use official CPI data?
- No. It only uses the fixed annual rate you enter and does not fetch external data.
- Is this investment advice?
- No. It is a math estimate. Real prices, exchange rates, taxes, fees, and product differences can vary.
