Put the years
in perspective.
A dollar amount only tells part of the story. Inflation Nation helps you compare its purchasing power with another year, so the difference is easier to understand.
Edit either dollar amount, move the year slider, and see the equivalent amount and cumulative inflation.

Good to know
Clear numbers.
Clear context.
A quick comparison of U.S. purchasing power, with the data reference shown inside the app.
Which currency does it compare?
U.S. dollars. The preview uses the U.S. Consumer Price Index for All Urban Consumers (CPI-U), not seasonally adjusted.
Is “total inflation” an annual rate?
No. It is the cumulative price change across the comparison period, rather than the inflation rate for a single year.
Does the data update automatically?
No. The preview contains a fixed data snapshot. Its footer labels the historical annual averages and latest stored monthly index. Check that reference when interpreting a result.
Where do I open the calculator?
Use any “Open Inflation Nation preview” button on this page. It opens the calculator in a separate tab, leaving this page available.
