# U.S. inflation rate in 1958: 2.85%

### Inflation in 1958 and Its Effect on Dollar Value

Purchasing power decreased by 2.85% in 1958 compared to 1957. On average, you would have to spend 2.85% more money in 1958 than in 1957 for the same item.

In other words, \$1 in 1957 is equivalent in purchasing power to about \$1.03 in 1958.

The 1957 inflation rate was 3.31%. The inflation rate in 1958 was 2.85%. The 1958 inflation rate is lower compared to the average inflation rate of 3.65% per year between 1958 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1958 was 28.90. It was 28.10 in the previous year, 1957. 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 1957 to 1958 (figures shown are purchasing power equivalents of \$1):

San Francisco, California experienced the highest rate of inflation during the 1 years between 1957 and 1958 (3.69%).

Detroit, Michigan experienced the lowest rate of inflation during the 1 years between 1957 and 1958 (1.38%).

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 1957 would be equivalent to £1.03 in 1958, an absolute change of £0.03 and a cumulative change of 3.20%.

In Canada, CA\$1.00 in 1957 would be equivalent to CA\$1.03 in 1958, an absolute change of CA\$0.03 and a cumulative change of 2.68%.

Compare these numbers to the US's overall absolute change of \$0.03 and total percent change of 2.85%.

### 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 1957 and 1958.

Compare these values to the overall average of 2.85% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1957 → 1958
Food 4.31 4.31 1.04
Shelter 2.12 2.12 1.02
Energy 0.19 0.19 1.00
Apparel 0.38 0.38 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 6.29 6.29 1.06
Medical care services 4.97 4.97 1.05
Medical care commodities 3.31 3.31 1.03

It's important to note that not all categories may be tracked since 1957. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1957 to 1958

This inflation calculator uses the following inflation rate formula:

CPI in 1958CPI in 1957
×
1957 USD value
=
1958 USD value

Then plug in historical CPI values. The U.S. CPI was 28.1 in the year 1957 and 28.9 in 1958:

28.928.1
×
\$1
=
\$1.03

\$1 in 1957 has the same "purchasing power" or "buying power" as \$1.03 in 1958.

To get the total inflation rate for the 1 years between 1957 and 1958, we use the following formula:

CPI in 1958 - CPI in 1957CPI in 1957
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

28.9 - 28.128.1
×
100
=
3%

### 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 1957, our investment would be nominally worth approximately \$1.32 in 1958. This is a return on investment of 32.23%, with an absolute return of \$0.32.

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 2.77% of returns (\$0.01) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.31.

Investment in S&P 500 Index, 1957-1958
Original Amount Final Amount Change
Nominal \$1 \$1.32 32.23%
Real
\$1 \$0.31 31.34%

Politics and news often influence economic performance. Here's what was happening at the time:

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (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.
