# U.S. inflation rate in 1798: -3.15%

### Inflation in 1798 and Its Effect on Dollar Value

Purchasing power increased by 3.15% in 1798 compared to 1797. On average, you would have to spend 3.15% less money in 1798 than in 1797 for the same item. This is an example of deflation.

In other words, \$1 in 1797 is equivalent in purchasing power to about \$0.97 in 1798.

The 1797 inflation rate was -3.79%. The inflation rate in 1798 was -3.15%. The 1798 inflation rate is lower compared to the average inflation rate of 1.38% per year between 1798 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1798 was 12.30. It was 12.70 in the previous year, 1797. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1798 CPI is less than 1797 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 1797 would be equivalent to £0.98 in 1798, an absolute change of £-0.02 and a cumulative change of -2.22%.

Compare these numbers to the US's overall absolute change of \$-0.03 and total percent change of -3.15%.

### 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 1797 and 1798.

Compare these values to the overall average of -3.15% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1797 → 1798
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 1797. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1797 to 1798

This inflation calculator uses the following inflation rate formula:

CPI in 1798CPI in 1797
×
1797 USD value
=
1798 USD value

Then plug in historical CPI values. The U.S. CPI was 12.7 in the year 1797 and 12.3 in 1798:

12.312.7
×
\$1
=
\$0.97

\$1 in 1797 has the same "purchasing power" or "buying power" as \$0.97 in 1798.

To get the total inflation rate for the 1 years between 1797 and 1798, we use the following formula:

CPI in 1798 - CPI in 1797CPI in 1797
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

12.3 - 12.712.7
×
100
=
-3%

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

• Napoleon prepares plans to invade Britain.
• First £1 note issued by the Bank of England
• The Dutch fleet is defeated by British navy in a Battle of Camperdown
