|Used cars and trucks||0.00||0.00||1.00|
|Medical care services||0.00||0.00||1.00|
|Medical care commodities||0.00||0.00||1.00|
It's important to note that not all categories may be tracked since 1820. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1820 and 12.7 in 1819:
$1 in 1820 has the same "purchasing power" or "buying power" as $1.09 in 1819.
To get the total inflation rate for the 1 years between 1819 and 1820, we use the following formula:
Plugging in the values to this equation, we get:
