Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1975 to 1977 (figures shown are purchasing power equivalents of $1):

Houston, Texas experienced the highest rate of inflation during the 2 years between 1975 and 1977 (7.41%).

Atlanta, Georgia experienced the lowest rate of inflation during the 2 years between 1975 and 1977 (5.35%).

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 1975 would be equivalent to £1.35 in 1977, an absolute change of £0.35 and a cumulative change of 35.01%.

In Canada, CA$1.00 in 1975 would be equivalent to CA$1.16 in 1977, an absolute change of CA$0.16 and a cumulative change of 15.56%.

Compare these numbers to the US's overall absolute change of $0.13 and total percent change of 12.64%.


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 1975 and 1977.

Compare these values to the overall average of 6.13% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1975 → 1977
Food 4.68 9.57 1.10
Shelter 6.12 12.61 1.13
Energy 8.36 17.41 1.17
Apparel 4.11 8.39 1.08
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 11.07 23.37 1.23
Medical care services 9.98 20.95 1.21
Medical care commodities 6.25 12.89 1.13

It's important to note that not all categories may be tracked since 1975. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $1, 1975 to 1977

This inflation calculator uses the following inflation rate formula:

CPI in 1977CPI in 1975
×
1975 USD value
=
1977 USD value

Then plug in historical CPI values. The U.S. CPI was 53.8 in the year 1975 and 60.6 in 1977:

60.653.8
×
$1
=
$1.13

$1 in 1975 has the same "purchasing power" or "buying power" as $1.13 in 1977.

To get the total inflation rate for the 2 years between 1975 and 1977, we use the following formula:

CPI in 1977 - CPI in 1975CPI in 1975
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

60.6 - 53.853.8
×
100
=
13%

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 6.41% per year between 1975 and 1977 (vs all-CPI inflation of 6.13%), for an inflation total of 13.23%.

When using the core inflation measurement, $1 in 1975 is equivalent in buying power to $1.13 in 1977, a difference of $0.13. Recall that for All Items, the converted amount is $1.13 with a difference of $0.13.

In 1975, core inflation was 9.21%.


Comparison to S&P 500 Index

The average inflation rate of 6.13% has a compounding effect between 1975 and 1977. As noted above, this yearly inflation rate compounds to produce an overall price difference of 12.64% over 2 years.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1975, our investment would be nominally worth approximately $1.41 in 1977. This is a return on investment of 40.80%, with an absolute return of $0.41.

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 11.22% of returns ($0.05) during this period. This means the inflation-adjusted real return of our $1 investment is $0.36.

Investment in S&P 500 Index, 1975-1977
Original Amount Final Amount Change
Nominal $1 $1.41 40.80%
Real
Inflation Adjusted
$1 $0.36 36.22%
