How it works
The price index, year by year.
02 / Maths
A simple ratio
Value in year B = amount × CPI in year B ÷ CPI in year A.
03 / Averages
Whole years
Each year uses the BLS yearly average, so months within a year are not shown.
Questions
Good to know.
How do I adjust an amount for inflation?
Multiply it by the CPI of the later year and divide by the CPI of the earlier year.
Where does the data come from?
The US Bureau of Labor Statistics, CPI-U yearly averages, series CUUR0000SA0, read on 17 October 2026.
Does it work for other countries?
No. It uses US prices only.
Why is the current year missing?
A yearly average exists only once the year is over and BLS has published it.
Is it exact for my own costs?
No. CPI is an average; rent, food or fuel in your area can change faster or slower.
