How to Calculate Inflation Rate for $1, 1809 to 1810

Our calculations use the following inflation rate formula to calculate the change in value between 1809 and 1810:

CPI in 1809 CPI in 1810
×
1810 USD value
=
1809 USD value

Then plug in historical CPI values. The U.S. CPI was 12.3 in the year 1810 and 12.3 in 1809:

12.312.3
×
$1
=
$1
