Formula and Assumptions

Future amount = current amount x (1 + inflation rate)^years.

This uses a constant average inflation rate rather than historical CPI tables.

The buying-power metric shows the same amount discounted by the inflation factor.

Reference Upgrade

Built from the Calculator.net model, with added context.

Live validation and instant result updates instead of a submit-only workflow.

Multiple decision metrics are shown together, not only the primary answer.

Formula notes and assumptions are visible on the page so the math is easier to audit.

Reference Model

Modeled after the input style and primary output on Calculator.net's Inflation Calculator.

The page keeps the math in one place and exposes the assumptions beside the result.

Default inputs: amount=100, startYear=2026, endYear=2036, inflationRate=3
