Inflation in 1779 and Its Effect on Dollar Value

Purchasing power increased by 11.59% in 1779 compared to the previous year, 1778. On average, you would have to spend 11.59% less money in 1779 than in 1778 for the same item. This is an example of deflation.

In other words, $100 in 1778 is equivalent in purchasing power to $88.41 in 1779.

The 1778 inflation rate was 30.19%. The inflation rate in 1779 was -11.59%. The 1779 inflation rate is lower compared to the average inflation rate of 1.28% per year between 1779 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1779 was 12.2. It was 13.8 in the previous year, 1778. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1779 CPI is less than 1778 CPI, negative inflation (also known as deflation) has occurred.
