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 $21.91 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $21.91 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 215 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 £86.89 in 2020, an absolute change of £85.89 and a cumulative change of 8,588.88%.

Compare these numbers to the US's overall absolute change of $20.91 and total percent change of 2,091.36%.


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 2020.

Compare these values to the overall average of 1.45% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1805 → 2020
Food and beverages 3.87 354,379.01 3,544.79

How to Calculate Inflation Rate for $1 since 1805

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

CPI today CPI in 1805
×
1805 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1805 and 256.389 in 2020:

256.38911.7
×
$1
=
$21.91

$1 in 1805 has the same "purchasing power" or "buying power" as $21.91 in 2020.

To get the total inflation rate for the 215 years between 1805 and 2020, we use the following formula:

CPI in 2020 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (215 years)

Plugging in the values to this equation, we get:

256.389 - 11.711.7
×
100
=
2,091%

News headlines from 1805
