Inflation in 1809 and Its Effect on Dollar Value

Purchasing power increased by 2.38% in 1809 compared to the previous year, 1808. On average, you would have to spend 2.38% less money in 1809 than in 1808 for the same item. This is an example of deflation.

In other words, $100 in 1808 is equivalent in purchasing power to $97.62 in 1809.

The 1808 inflation rate was 8.62%. The inflation rate in 1809 was -2.38%. The 1809 inflation rate is lower compared to the average inflation rate of 1.46% per year between 1809 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1809 was 12.3. It was 12.6 in the previous year, 1808. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1809 CPI is less than 1808 CPI, negative inflation (also known as deflation) has occurred.
