Inflation in 1843 and Its Effect on Dollar Value

Purchasing power increased by 9.76% in 1843 compared to the previous year, 1842. On average, you would have to spend 9.76% less money in 1843 than in 1842 for the same item. This is an example of deflation.

In other words, $100 in 1842 is equivalent in purchasing power to $90.24 in 1843.

The 1842 inflation rate was -5.75%. The inflation rate in 1843 was -9.76%. The 1843 inflation rate is lower compared to the average inflation rate of 2.04% per year between 1843 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1843 was 7.4. It was 8.2 in the previous year, 1842. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1843 CPI is less than 1842 CPI, negative inflation (also known as deflation) has occurred.

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1842 would be equivalent to £89.00 in 1843, an absolute change of £-11.00 and a cumulative change of -11.00%.

Compare these numbers to the US's overall absolute change of $-9.76 and total percent change of -9.76%.


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 1842 and 1843.

Compare these values to the overall average of -9.76% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1842 → 1843
Food 0.00 0.00 100.00
Shelter 0.00 0.00 100.00
Energy 0.00 0.00 100.00

It's important to note that not all categories may be tracked since 1842. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1842 to 1843

This inflation calculator uses the following inflation rate formula:

CPI in 1843CPI in 1842
×
1842 USD value
=
1843 USD value

Then plug in historical CPI values. The U.S. CPI was 8.2 in the year 1842 and 7.4 in 1843:

7.48.2
×
$100
=
$90.24

$100 in 1842 has the same "purchasing power" or "buying power" as $90.24 in 1843.

To get the total inflation rate for the 1 years between 1842 and 1843, we use the following formula:

CPI in 1843 - CPI in 1842CPI in 1842
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

7.4 - 8.28.2
×
100
=
-10%
