### Inflation in 1803 and Its Effect on Dollar Value

Purchasing power decreased by 5.61% in 1803 compared to 1802. On average, you would have to spend 5.61% more money in 1803 than in 1802 for the same item.

In other words, \$1 in 1802 is equivalent in purchasing power to about \$1.06 in 1803.

The 1802 inflation rate was -15.75%. The inflation rate in 1803 was 5.61%. The 1803 inflation rate is higher compared to the average inflation rate of 1.46% per year between 1803 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1803 was 11.30. It was 10.70 in the previous year, 1802. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1802 would be equivalent to £0.95 in 1803, an absolute change of £-0.05 and a cumulative change of -5.17%.

Compare these numbers to the US's overall absolute change of \$0.06 and total percent change of 5.61%.

### 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 1802 and 1803.

Compare these values to the overall average of 5.61% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1802 → 1803
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 0.00 0.00 1.00
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1802. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1802 to 1803

This inflation calculator uses the following inflation rate formula:

CPI in 1803CPI in 1802
×
1802 USD value
=
1803 USD value

Then plug in historical CPI values. The U.S. CPI was 10.7 in the year 1802 and 11.3 in 1803:

11.310.7
×
\$1
=
\$1.06

\$1 in 1802 has the same "purchasing power" or "buying power" as \$1.06 in 1803.

To get the total inflation rate for the 1 years between 1802 and 1803, we use the following formula:

CPI in 1803 - CPI in 1802CPI in 1802
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

11.3 - 10.710.7
×
100
=
6%

Politics and news often influence economic performance. Here's what was happening at the time:

• Napoleon is elected president of the Italian Republic (Cisalpine Republic)
• Aime Bonpland and Alexander von Humbolt arrive at Quito, Ecuador
• Congress passes an act calling for a US Capitol library.
