### Inflation in 1813 and Its Effect on Dollar Value

Purchasing power decreased by 20.30% in 1813 compared to 1812. On average, you would have to spend 20.30% more money in 1813 than in 1812 for the same item.

In other words, \$1 in 1812 is equivalent in purchasing power to about \$1.20 in 1813.

The 1812 inflation rate was 1.53%. The inflation rate in 1813 was 20.30%. The 1813 inflation rate is higher compared to the average inflation rate of 1.35% per year between 1813 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1813 was 16.00. It was 13.30 in the previous year, 1812. 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 1812 would be equivalent to £1.03 in 1813, an absolute change of £0.03 and a cumulative change of 2.52%.

Compare these numbers to the US's overall absolute change of \$0.20 and total percent change of 20.30%.

### 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 1812 and 1813.

Compare these values to the overall average of 20.30% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1812 → 1813
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1812. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1812 to 1813

This inflation calculator uses the following inflation rate formula:

CPI in 1813CPI in 1812
×
1812 USD value
=
1813 USD value

Then plug in historical CPI values. The U.S. CPI was 13.3 in the year 1812 and 16 in 1813:

1613.3
×
\$1
=
\$1.20

\$1 in 1812 has the same "purchasing power" or "buying power" as \$1.20 in 1813.

To get the total inflation rate for the 1 years between 1812 and 1813, we use the following formula:

CPI in 1813 - CPI in 1812CPI in 1812
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

16 - 13.313.3
×
100
=
20%

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

• Arthur Wellesley, first Duke of Wellington, orders British troops to storm Ciudad Rodrigo after a 10-day-long siege.
• The 1812 War begins as the United States declares war against Britain.
• Napoleon's occupation of Moscow begins.
