Frequently asked questions
What is CPI-U?
The Consumer Price Index for All Urban Consumers, published by the US Bureau of Labor Statistics — it tracks average price changes across a broad basket of goods and services and is the standard measure used for inflation calculators like this one.
Why might this not match my personal experience of inflation?
CPI-U is a broad national average. Your actual cost of living depends on what you buy and where you live — categories like housing or healthcare can rise faster or slower than the overall average in your specific situation.
