The U.S. dollar experienced an **average inflation rate** of 2.08% per year between 2000 and 2017. $100 in the year 2000 is worth $142.00 in 2017.

The **current inflation rate** in 2017 is 1.88%^{1}.

**How to calculate inflation since 2000**

Start with the CPI inflation formula:

CPI in 2017 / CPI in 2000 * 2000 USD value = 2017 USD value

Then plug in historical CPI values. The U.S. CPI was 172.2 in the year 2000 and 244.524 in 2017:

244.524 / 172.2 * $100 = **$142.00**

The "purchasing power" of $100 from 2000 is $142.00 in 2017.
