How to use this tool
Enter a US dollar amount and choose two available annual-average years.
Read the equivalent purchasing power using the stated historical CPI-U snapshot. It is not a forecast or your household's personal inflation rate.
Equivalent dollars = amount × CPI(to year) / CPI(from year)
