Inflation conversion method and source check

The calculator compounds an annual inflation assumption across the selected years to compare purchasing power between two points in time. It illustrates a mathematical relationship and does not forecast the actual price of a specific household item, service, or location.

State whether the amount is being converted into future dollars or today's dollars and keep that basis consistent with other projections. Historical CPI data can inform a scenario, but individual spending patterns differ from a broad index. Run more than one assumption when the result affects a long-term decision.
