ECONOMY STUDIOWhat's your $100 worth?
Pick any amount and any two years since 1913. We'll show what it's worth, using the official US consumer price index.
How it works
The calculator compares the Consumer Price Index (CPI-U) of the two years: value = amount × CPI in the second year ÷ CPI in the first. Full years use the yearly averages the Bureau of Labor Statistics publishes; 2026 uses the latest month, October 2026.
US inflation is currently 3.7% a year (see the latest data).
Questions
How much is $100 from 2000 worth today?
About $196.00. Put the other way, $100 today buys what about $51.02 bought in 2000.
How far back does it go?
To 1913, when the Bureau of Labor Statistics started the CPI. Prices today are about 34 times their 1913 level.
Is this the same for everyone?
No. The CPI tracks the spending of a typical urban household. Your own costs depend on what you buy, and where.
Why is this year marked with its latest month?
The year isn't over, so the calculator uses the most recent monthly index instead of a yearly average. It updates itself when each new inflation report comes out.
