## Value of \$1 from 1805 to 1811

According to the Bureau of Labor Statistics consumer price index, prices in 1811 are 11.97% higher than average prices since 1805. The U.S. dollar experienced an average inflation rate of 1.90% per year during this period, causing the real value of a dollar to decrease.

In other words, \$1 in 1805 is equivalent in purchasing power to about \$1.12 in 1811, a difference of \$0.12 over 6 years.

The 1805 inflation rate was -0.85%. The inflation rate in 1811 was 6.50%. The 1811 inflation rate is higher compared to the average inflation rate of 1.43% per year between 1811 and 2020.

## Buying power of \$1 in 1805

This chart shows a calculation of buying power equivalence for \$1 in 1805 (price index tracking began in 1635).

For example, if you started with \$1, you would need to end with \$1.12 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$1.12 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1805 dollars, the chart below shows how \$1 is worth less over 6 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1805 would be equivalent to £1.07 in 1811, an absolute change of £0.07 and a cumulative change of 6.87%.

Compare these numbers to the US's overall absolute change of \$0.12 and total percent change of 11.97%.

## Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes. This chart shows the average rate of inflation for select CPI categories between 1805 and 1811.

Compare these values to the overall average of 1.90% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1805 → 1811
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00

## How to Calculate Inflation Rate for \$1, 1805 to 1811

Our calculations use the following inflation rate formula to calculate the change in value between 1805 and 1811:

CPI in 1811 CPI in 1805
×
1805 USD value
=
1811 USD value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1805 and 13.1 in 1811:

13.111.7
×
\$1
=
\$1.12

\$1 in 1805 has the same "purchasing power" or "buying power" as \$1.12 in 1811.

To get the total inflation rate for the 6 years between 1805 and 1811, we use the following formula:

CPI in 1811 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (6 years)

Plugging in the values to this equation, we get:

13.1 - 11.711.7
×
100
=
12%

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
• The Rocky Mountains are seen for the first time by Lewis and Clark on their expedition.

## Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
