For all these visualizations, it's important to note that not all categories may have been tracked since 1805. This table and charts use the earliest available data for each category.

How to Calculate Inflation Rate for \$1, 1804 to 1805

This inflation calculator uses the following inflation rate formula:

CPI in 1804CPI in 1805
×
1805 USD value
=
1804 USD value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1805 and 11.8 in 1804:

11.811.7
×
\$1
=
\$1.01

\$1 in 1805 has the same "purchasing power" or "buying power" as \$1.01 in 1804.

To get the total inflation rate for the 1 years between 1804 and 1805, we use the following formula:

CPI in 1804 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

11.8 - 11.711.7

=
1%

Politics and news often influence economic performance. Here's what was happening at the time:

• The British navy, led by Admiral Horatio Nelson, defeat the French and Spanish fleet in the Battle of Trafalgar. Admiral Nelson is killed during battle.
• The American West is crossed for the first time when an expedition, led by Lewis Clark, reaches the Pacific Ocean
