How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
With 0% inflation, both figures remain $10,000; positive inflation reduces purchasing power of a fixed amount.
The formula
Purchasing power in today’s dollars = amount ÷ (1 + inflation)^years. Required future dollars = amount × (1 + inflation)^years.
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Constant entered inflation; no historical or forecast inflation series is fetched.
