# U.S. inflation rate in 1815: -12.50%

### Inflation in 1815 and Its Effect on Dollar Value

Purchasing power increased by 12.50% in 1815 compared to 1814. On average, you would have to spend 12.50% less money in 1815 than in 1814 for the same item. This is an example of deflation.

In other words, \$1 in 1814 is equivalent in purchasing power to about \$0.88 in 1815.

The 1814 inflation rate was 10.00%. The inflation rate in 1815 was -12.50%. The 1815 inflation rate is lower compared to the average inflation rate of 1.39% per year between 1815 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1815 was 15.40. It was 17.60 in the previous year, 1814. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1815 CPI is less than 1814 CPI, negative inflation (also known as deflation) has occurred.

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1814 would be equivalent to £0.89 in 1815, an absolute change of £-0.11 and a cumulative change of -10.56%.

Compare these numbers to the US's overall absolute change of \$-0.12 and total percent change of -12.50%.

### 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 1814 and 1815.

Compare these values to the overall average of -12.50% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1814 → 1815
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 1814. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1814 to 1815

This inflation calculator uses the following inflation rate formula:

CPI in 1815CPI in 1814
×
1814 USD value
=
1815 USD value

Then plug in historical CPI values. The U.S. CPI was 17.6 in the year 1814 and 15.4 in 1815:

15.417.6
×
\$1
=
\$0.88

\$1 in 1814 has the same "purchasing power" or "buying power" as \$0.88 in 1815.

To get the total inflation rate for the 1 years between 1814 and 1815, we use the following formula:

CPI in 1815 - CPI in 1814CPI in 1814
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

15.4 - 17.617.6
×
100
=
-12%

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

• Napoleon abdicates and is exiled to Elba.
• George Stephenson, an English engineer, introduces the first steam locomotive.
• British forces capture and destroy many parts of Washington D.C. in the continuing 1812 war.
• The Congress of Vienna opens: one of its goals is to redraw Europe's political map after Napoleon's defeat.

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
