U.S. inflation rate in 1974: 11.04%

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1973 to 1974 (figures shown are purchasing power equivalents of $1):

• Philadelphia, Pennsylvania: 11.87% average rate, $1 → $1.12, cumulative change of 11.87%
• Houston, Texas: 11.17% average rate, $1 → $1.11, cumulative change of 11.17%
• Atlanta, Georgia: 10.85% average rate, $1 → $1.11, cumulative change of 10.85%
• Detroit, Michigan: 10.83% average rate, $1 → $1.11, cumulative change of 10.83%
• New York: 10.76% average rate, $1 → $1.11, cumulative change of 10.76%
• Seattle, Washington: 10.66% average rate, $1 → $1.11, cumulative change of 10.66%
• Chicago, Illinois: 10.57% average rate, $1 → $1.11, cumulative change of 10.57%
• Boston, Massachusetts: 10.33% average rate, $1 → $1.10, cumulative change of 10.33%
• Dallas-Fort Worth, Texas: 9.92% average rate, $1 → $1.10, cumulative change of 9.92%
• San Francisco, California: 9.32% average rate, $1 → $1.09, cumulative change of 9.32%

Philadelphia, Pennsylvania experienced the highest rate of inflation during the 1 years between 1973 and 1974 (11.87%).

San Francisco, California experienced the lowest rate of inflation during the 1 years between 1973 and 1974 (9.32%).

Note that some locations showing 0% inflation may have not yet reported latest data.

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1973 would be equivalent to £1.16 in 1974, an absolute change of £0.16 and a cumulative change of 16.04%.

In Canada, CA$1.00 in 1973 would be equivalent to CA$1.11 in 1974, an absolute change of CA$0.11 and a cumulative change of 11.00%.

Compare these numbers to the US's overall absolute change of $0.11 and total percent change of 11.04%.

Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

This chart shows the average rate of inflation for select CPI categories between 1973 and 1974.

Compare these values to the overall average of 11.04% per year:

For all these visualizations, it's important to note that not all categories may have been tracked since 1973. This table and charts use the earliest available data for each category.

How to calculate inflation rate for $1, 1973 to 1974

Our calculations use the following inflation rate formula to calculate the change in value between 1973 and 1974:

Then plug in historical CPI values. The U.S. CPI was 44.4 in the year 1973 and 49.3 in 1974:

$1 in 1973 has the same "purchasing power" or "buying power" as $1.11 in 1974.

To get the total inflation rate for the 1 years between 1973 and 1974, we use the following formula:

Plugging in the values to this equation, we get:

Alternate Measurements of Inflation

There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.

Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.

Personal Consumption Expenditures (PCE) Inflation

The PCE Price Index is the U.S. Federal Reserve's preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.

The PCE Price Index changed by 10.41% per year on average between 1973 and 1974. The total PCE inflation between these dates was 10.41%. In 1973, PCE inflation was 5.38%.

This means that the PCE Index equates $1 in 1973 with $1.10 in 1974, a difference of $0.10. Compare this to the standard CPI measurement, which equates $1 with $1.11. The PCE measured -0.63% inflation compared to standard CPI.

For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.

Core Inflation

Also of note is the Core CPI, which uses the standard CPI but omits the more volatile categories of food and energy.

Core inflation averaged 8.25% per year between 1973 and 1974 (vs all-CPI inflation of 11.04%), for an inflation total of 8.25%. In 1973, core inflation was 3.49%.

When using the core inflation measurement, $1 in 1973 is equivalent in buying power to $1.08 in 1974, a difference of $0.08. Recall that the converted amount is $1.11 when all items including food and energy are measured.

Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1973, our investment would be nominally worth approximately $0.66 in 1974. This is a return on investment of -33.93%, with an absolute return of $-0.34 on top of the original $1.

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 9.94% of returns ($0.07) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.40. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 1973 to latest available data for 1974 using average monthly close price.
