Inflation in 1851 and Its Effect on Dollar Value

Purchasing power increased by 1.28% in 1851 compared to the previous year, 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, $100 in 1850 is equivalent in purchasing power to $98.72 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 2.11% per year between 1851 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1851 was 7.7. It was 7.8 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.

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

How to Calculate Inflation Rate for $100, 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
×
$100
=
$98.72

$100 in 1850 has the same "purchasing power" or "buying power" as $98.72 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
