# U.S. inflation rate in 1851: -1.28%

### Inflation in 1851 and Its Effect on Dollar Value

Purchasing power increased by 1.28% in 1851 compared to 1850. On average, you would have to spend 1.28% less money in 1851 than in 1850 for the same item. This is an example of deflation.

In other words, \$1 in 1850 is equivalent in purchasing power to about \$0.99 in 1851.

The 1850 inflation rate was 1.30%. The inflation rate in 1851 was -1.28%. The 1851 inflation rate is lower compared to the average inflation rate of 2.10% per year between 1851 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1851 was 7.70. It was 7.80 in the previous year, 1850. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1851 CPI is less than 1850 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 1850 would be equivalent to £0.96 in 1851, an absolute change of £-0.04 and a cumulative change of -3.57%.

Compare these numbers to the US's overall absolute change of \$-0.01 and total percent change of -1.28%.

### 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 1850 and 1851.

Compare these values to the overall average of -1.28% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1850 → 1851
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 1850. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1850 to 1851

This inflation calculator uses the following inflation rate formula:

CPI in 1851CPI in 1850
×
1850 USD value
=
1851 USD value

Then plug in historical CPI values. The U.S. CPI was 7.8 in the year 1850 and 7.7 in 1851:

7.77.8
×
\$1
=
\$0.99

\$1 in 1850 has the same "purchasing power" or "buying power" as \$0.99 in 1851.

To get the total inflation rate for the 1 years between 1850 and 1851, we use the following formula:

CPI in 1851 - CPI in 1850CPI in 1850
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

7.7 - 7.87.8
×
100
=
-1%

### News headlines from 1850

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

• The California Exchange is opened.
• Britain blockades Piraeus, a Greek port.
• The HMS Investigator sets sail from Woolwich, England, becoming the first ship to explore the Northwest Passage.

### 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.
