Inflation in 1975 and Its Effect on Dollar Value

Purchasing power decreased by 9.13% in 1975 compared to the previous year, 1974. On average, you would have to spend 9.13% more money in 1975 than in 1974 for the same item.

In other words, $1 in 1974 is equivalent in purchasing power to $1.09 in 1975.

The 1974 inflation rate was 11.04%. The inflation rate in 1975 was 9.13%. The 1975 inflation rate is higher compared to the average inflation rate of 3.66% per year between 1975 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1975 was 53.8. It was 49.3 in the previous year, 1974. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1974 to 1975 (figures shown are purchasing power equivalents of $1):

Houston, Texas experienced the highest rate of inflation during the 1 years between 1974 and 1975 (12.18%).

Detroit, Michigan experienced the lowest rate of inflation during the 1 years between 1974 and 1975 (7.45%).

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 1974 would be equivalent to £1.24 in 1975, an absolute change of £0.24 and a cumulative change of 24.24%.

In Canada, CA$1.00 in 1974 would be equivalent to CA$1.09 in 1975, an absolute change of CA$0.09 and a cumulative change of 9.42%.

Compare these numbers to the US's overall absolute change of $0.09 and total percent change of 9.13%.


Inflation by Spending Category

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 1974 and 1975.

Compare these values to the overall average of 9.13% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1974 → 1975
Food 8.49 8.49 1.08
Shelter 9.87 9.87 1.10
Energy 10.60 10.60 1.11
Apparel 4.45 4.45 1.04
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 12.60 12.60 1.13
Medical care commodities 8.41 8.41 1.08

It's important to note that not all categories may be tracked since 1974. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $1, 1974 to 1975

This inflation calculator uses the following inflation rate formula:

CPI in 1975CPI in 1974
×
1974 USD value
=
1975 USD value

Then plug in historical CPI values. The U.S. CPI was 49.3 in the year 1974 and 53.8 in 1975:

53.849.3
×
$1
=
$1.09

$1 in 1974 has the same "purchasing power" or "buying power" as $1.09 in 1975.

To get the total inflation rate for the 1 years between 1974 and 1975, we use the following formula:

CPI in 1975 - CPI in 1974CPI in 1974
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

53.8 - 49.349.3
×
100
=
9%

Alternate Measurements of Inflation

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 9.22% per year between 1974 and 1975 (vs all-CPI inflation of 9.13%), for an inflation total of 9.22%.

When using the core inflation measurement, $1 in 1974 is equivalent in buying power to $1.09 in 1975, a difference of $0.09. Recall that for All Items, the converted amount is $1.09 with a difference of $0.09.

In 1974, core inflation was 8.30%.


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 1974, our investment would be nominally worth approximately $1.10 in 1975. This is a return on investment of 9.86%, with an absolute return of $0.10.

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 8.36% of returns ($0.01) during this period. This means the inflation-adjusted real return of our $1 investment is $0.09.

Investment in S&P 500 Index, 1974-1975
Original Amount Final Amount Change
Nominal $1 $1.10 9.86%
Real
Inflation Adjusted
$1 $0.09 9.03%
