Purchasing power decreased by 6.22% in 1973 compared to 1972. On average, you would have to spend 6.22% more money in 1973 than in 1972 for the same item.
In other words, $1 in 1972 is equivalent in purchasing power to about $1.06 in 1973.
The 1972 inflation rate was 3.21%. The inflation rate in 1973 was 6.22%. The 1973 inflation rate is higher compared to the average inflation rate of 3.88% per year between 1973 and 2019.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1973 was 44.40. It was 41.80 in the previous year, 1972. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.
|Average inflation rate||6.22%|
|Converted amount ($1 base)||$1.06|
|Price difference ($1 base)||$0.06|
|CPI in 1972||41.800|
|CPI in 1973||44.400|
|Inflation in 1972||3.21%|
|Inflation in 1973||6.22%|
Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1972 to 1973 (figures shown are purchasing power equivalents of $1):
Philadelphia, Pennsylvania experienced the highest rate of inflation during the 1 years between 1972 and 1973 (6.73%).
Dallas-Fort Worth, Texas experienced the lowest rate of inflation during the 1 years between 1972 and 1973 (5.18%).
Note that some locations showing 0% inflation may have not yet reported latest data.
Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1972 would be equivalent to £1.09 in 1973, an absolute change of £0.09 and a cumulative change of 9.10%.
In Canada, CA$1.00 in 1972 would be equivalent to CA$1.09 in 1973, an absolute change of CA$0.09 and a cumulative change of 9.38%.
Compare these numbers to the US's overall absolute change of $0.06 and total percent change of 6.22%.
CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1972 and 1973.
Compare these values to the overall average of 6.22% per year:
|Category||Avg Inflation (%)||Total Inflation (%)||$1 in 1972 → 1973|
|Used cars and trucks||0.00||0.00||1.00|
|Medical care services||4.45||4.45||1.04|
|Medical care commodities||0.28||0.28||1.00|
It's important to note that not all categories may be tracked since 1972. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 41.8 in the year 1972 and 44.4 in 1973:
$1 in 1972 has the same "purchasing power" or "buying power" as $1.06 in 1973.
To get the total inflation rate for the 1 years between 1972 and 1973, we use the following formula:
Plugging in the values to this equation, we get:
The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 3.49% per year between 1972 and 1973 (vs all-CPI inflation of 6.22%), for an inflation total of 3.49%.
When using the core inflation measurement, $1 in 1972 is equivalent in buying power to $1.03 in 1973, a difference of $0.03. Recall that for All Items, the converted amount is $1.06 with a difference of $0.06.
In 1972, core inflation was 3.06%.
To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1972, our investment would be nominally worth approximately $0.99 in 1973. This is a return on investment of -1.33%, with an absolute return of $-0.01.
These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.
The compounding effect of inflation would account for 5.86% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.01.

Politics and news often influence economic performance. Here's what was happening at the time:
Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
