Purchasing power increased by 16.07% in 1921 compared to 1920. On average, you would have to spend 16.07% less money in 1921 than in 1920 for the same item. This is an example of deflation.
In other words, CA$1 in 1920 is equivalent in purchasing power to about CA$0.84 in 1921.
The 1920 inflation rate was 9.80%. The inflation rate in 1921 was -16.07%. The 1921 inflation rate is lower compared to the average inflation rate of 2.74% per year between 1921 and 2019.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1921 was 9.40. It was 11.20 in the previous year, 1920. The difference in CPI between the years is used by Statistics Canada to officially determine inflation. Because the 1921 CPI is less than 1920 CPI, negative inflation (also known as deflation) has occurred.
|Average inflation rate||-16.07%|
|Converted amount (CA$1 base)||CA$0.84|
|Price difference (CA$1 base)||CA$-0.16|
|CPI in 1920||11.200|
|CPI in 1921||9.400|
|Inflation in 1920||9.80%|
|Inflation in 1921||-16.07%|
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The Canadian CPI was 11.2 in the year 1920 and 9.4 in 1921:
CA$1 in 1920 has the same "purchasing power" or "buying power" as CA$0.84 in 1921.
To get the total inflation rate for the 1 years between 1920 and 1921, we use the following formula:
Plugging in the values to this equation, we get:
