Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1805 would be equivalent to £1.15 in 1801, an absolute change of £0.15 and a cumulative change of 15.27%.

Compare these numbers to the US's overall absolute change of $0.09 and total percent change of 8.55%.


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 1801.

Compare these values to the overall average of -2.03% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1801 → 1805
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, 1801 to 1805

Our calculations use the following inflation rate formula to calculate the change in value between 1801 and 1805:

CPI in 1801 CPI in 1805
×
1805 USD value
=
1801 USD value

Then plug in historical CPI values. The U.S. CPI was 11.7 in the year 1805 and 12.7 in 1801:

12.711.7
×
$1
=
$1.09

$1 in 1805 has the same "purchasing power" or "buying power" as $1.09 in 1801.

To get the total inflation rate for the 4 years between 1801 and 1805, we use the following formula:

CPI in 1801 - CPI in 1805CPI in 1805
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

12.7 - 11.711.7
×
100
=
9%

News headlines from 1801
