Buying power of $1 in 1806

This chart shows a calculation of buying power equivalence for $1 in 1806 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $21.02 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $21.02 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 1806 dollars, the chart below shows how $1 is worth less over 214 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 1806 would be equivalent to £90.34 in 2020, an absolute change of £89.34 and a cumulative change of 8,933.68%.

Compare these numbers to the US's overall absolute change of $20.02 and total percent change of 2,001.59%.


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 1806 and 2020.

Compare these values to the overall average of 1.43% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1806 → 2020
Food and beverages 3.88 346,837.73 3,469.38

How to Calculate Inflation Rate for $1 since 1806

Our calculations use the following inflation rate formula to calculate the change in value between 1806 and today:

CPI today CPI in 1806
×
1806 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 12.2 in the year 1806 and 256.394 in 2020:

256.39412.2
×
$1
=
$21.02

$1 in 1806 has the same "purchasing power" or "buying power" as $21.02 in 2020.

To get the total inflation rate for the 214 years between 1806 and 2020, we use the following formula:

CPI in 2020 - CPI in 1806CPI in 1806
×
100
=
Cumulative inflation rate (214 years)

Plugging in the values to this equation, we get:

256.394 - 12.212.2
×
100
=
2,002%

News headlines from 1806
