$1 in 1920 is equivalent in purchasing power to about $0.88 in 1921. The dollar had an average deflation rate of -12.11% per year since 1920, producing a cumulative price change of -12.11%. Purchasing power increased by 12.11% in 1921 compared to 1920. On average, you would have to spend 12.11% less money in 1921 than in 1920 for the same item. This is an example of deflation.
This means that prices in 1921 are 12.11% lower than average prices since 1920, according to Statistics Canada consumer price index.
The inflation rate in 1920 was 16.30%. The inflation rate in 1921 was -12.11%. The 1921 inflation rate is lower compared to the average inflation rate of 2.72% per year between 1921 and 2024.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1921 was 9.98. It was 11.36 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.

Our calculations use the following inflation rate formula to calculate the change in value between 1920 and 1921:
Then plug in historical CPI values. The Canadian CPI was 11.35833333 in the year 1920 and 9.983333333 in 1921:
$1 in 1920 has the same "purchasing power" or "buying power" as $0.88 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:
Raw data for these calculations comes from the government of Canada's annual Consumer Price Index (CPI), established in 1914 and computed by Statistics Canada (StatCan).
