How to read this estimate

The projection is a constant-rate scenario, not a forecast or live inflation reading. Negative inflation and raises are allowed. Real change is compounded, not calculated by simply subtracting rates.

Historical conversion = amount × ending CPI / starting CPI. Use the same index series and comparable time periods for both values. Saved period choices use BLS monthly CPI-U, U.S. city average, all items, not seasonally adjusted. Defaults compare December 2020 with December 2025. You can enter custom indexes; the dated snapshot is not refreshed automatically.

The BLS CPI measures average consumer price change. Your household basket and location can differ; the index does not predict your personal costs.
