How to calculate inflation rate for $1, 1810 to 1811
Our calculations use the following inflation rate formula to calculate the change in value between 1810 and 1811:
CPI in 1811 CPI in 1810
×
1810 USD value
=
1811 USD value
Then plug in historical CPI values. The U.S. CPI was 12.3 in the year 1810 and 13.1 in 1811:
13.112.3
×
$1
=
$1.07
$1 in 1810 has the same "purchasing power" or "buying power" as $1.07 in 1811.
To get the total inflation rate for the 1 years between 1810 and 1811, we use the following formula:
CPI in 1811 - CPI in 1810CPI in 1810
×
100
=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
13.1 - 12.312.3
×
100
=
7%
