Frequently asked questions
How does this calculator work?
It compounds a constant average inflation rate you choose: future cost = amount × (1 + rate)^years, and buying power = amount ÷ (1 + rate)^years.
Does it use live inflation data?
No — it runs entirely in your browser with the average rate you enter, so you can model any scenario. For historical CPI you would need a live data source.
