Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1800 would be equivalent to £97.04 in 1805, an absolute change of £-2.96 and a cumulative change of -2.96%.

Compare these numbers to the US's overall absolute change of $-7.14 and total percent change of -7.14%.


Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1800 and 1805.

Compare these values to the overall average of -1.47% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1800 → 1805
Food 0.00 0.00 100.00
Shelter 0.00 0.00 100.00
Energy 0.00 0.00 100.00
Apparel 0.00 0.00 100.00
New vehicles 0.00 0.00 100.00
Used cars and trucks 0.00 0.00 100.00
Transportation services 0.00 0.00 100.00
Medical care services 0.00 0.00 100.00
Medical care commodities 0.00 0.00 100.00

It's important to note that not all categories may be tracked since 1800. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1800 to 1805

This inflation calculator uses the following inflation rate formula:

CPI in 1805CPI in 1800
×
1800 USD value
=
1805 USD value

Then plug in historical CPI values. The U.S. CPI was 12.6 in the year 1800 and 11.7 in 1805:

11.712.6
×
$100
=
$92.86

$100 in 1800 has the same "purchasing power" or "buying power" as $92.86 in 1805.

To get the total inflation rate for the 5 years between 1800 and 1805, we use the following formula:

CPI in 1805 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

11.7 - 12.612.6
×
100
=
-7%
