How to calculate inflation rate for $1, 1800 to 1900
Our calculations use the following inflation rate formula to calculate the change in value between 1800 and 1900:
CPI in 1900 CPI in 1800
×
1800 USD value
=
1900 USD value
Then plug in historical CPI values. The U.S. CPI was 12.6 in the year 1800 and 8.4 in 1900:
8.412.6
×
$1
=
$0.67
$1 in 1800 has the same "purchasing power" or "buying power" as $0.67 in 1900.
To get the total inflation rate for the 100 years between 1800 and 1900, we use the following formula:
CPI in 1900 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (100 years)
Plugging in the values to this equation, we get:
8.4 - 12.612.6
×
