# U.S. inflation rate in 1783: -12.40%

### Inflation in 1783 and Its Effect on Dollar Value

Purchasing power increased by 12.40% in 1783 compared to 1782. On average, you would have to spend 12.40% less money in 1783 than in 1782 for the same item. This is an example of deflation.

In other words, \$1 in 1782 is equivalent in purchasing power to about \$0.88 in 1783.

The 1782 inflation rate was 9.01%. The inflation rate in 1783 was -12.40%. The 1783 inflation rate is lower compared to the average inflation rate of 1.36% per year between 1783 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1783 was 10.60. It was 12.10 in the previous year, 1782. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1783 CPI is less than 1782 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 1782 would be equivalent to £1.12 in 1783, an absolute change of £0.12 and a cumulative change of 11.94%.

Compare these numbers to the US's overall absolute change of \$-0.12 and total percent change of -12.40%.

### 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 1782 and 1783.

Compare these values to the overall average of -12.40% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1782 → 1783
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 1782. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1782 to 1783

This inflation calculator uses the following inflation rate formula:

CPI in 1783CPI in 1782
×
1782 USD value
=
1783 USD value

Then plug in historical CPI values. The U.S. CPI was 12.1 in the year 1782 and 10.6 in 1783:

10.612.1
×
\$1
=
\$0.88

\$1 in 1782 has the same "purchasing power" or "buying power" as \$0.88 in 1783.

To get the total inflation rate for the 1 years between 1782 and 1783, we use the following formula:

CPI in 1783 - CPI in 1782CPI in 1782
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

10.6 - 12.112.1
×
100
=
-12%

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

• The Bank of North America opens in Philadelphia, it is the first US commercial bank
• Rama I overthrows King Taksin of Siam (now known as Thailand).
• The US mint is established by a resolution of Congress
