For all these visualizations, it's important to note that not all categories may have been tracked since 1821. This table and charts use the earliest available data for each category.
How to Calculate Inflation Rate for $100, 1821 to 2017
This inflation calculator uses the following inflation rate formula:
CPI in 2017CPI in 1821
×
1821 USD value
=
2017 USD value
Then plug in historical CPI values. The U.S. CPI was 11.3 in the year 1821 and 245.12 in 2017:
245.1211.3
×
$100
=
$2,169.20
$100 in 1821 has the same "purchasing power" or "buying power" as $2,169.20 in 2017.
To get the total inflation rate for the 196 years between 1821 and 2017, we use the following formula:
CPI in 2017 - CPI in 1821CPI in 1821
×
100
=
Cumulative inflation rate (196 years)
Plugging in the values to this equation, we get:
245.12 - 11.311.3
×
100
=
2,069%
