Frequently Asked Questions
Where is the historical CPI index data sourced from?
Data is derived from the United States Bureau of Labor Statistics (BLS) Consumer Price Index for All Urban Consumers (CPI-U), tracking the average change over time in prices paid for goods and services.
How does the calculator determine CPI for unlisted intermediary years?
For years falling between benchmark decennial records, the calculator computes linear interpolation across the surrounding official CPI-U anchor points.
Are salary inputs or inflation searches recorded or tracked online?
No. All inflation adjustments and historical comparisons evaluate entirely within your browser runtime without sending data to remote servers.
