\$

Value of \$1 from 1955 to 1957

According to the Bureau of Labor Statistics consumer price index, prices in 1957 are 4.85% higher than average prices since 1955. The U.S. dollar experienced an average inflation rate of 2.40% per year during this period, causing the real value of a dollar to decrease.

In other words, \$1 in 1955 is equivalent in purchasing power to about \$1.05 in 1957, a difference of \$0.05 over 2 years.

The 1955 inflation rate was -0.37%. The inflation rate in 1957 was 3.31%. The 1957 inflation rate is lower compared to the average inflation rate of 3.57% per year between 1957 and 2020.

Buying power of \$1 in 1955

This chart shows a calculation of buying power equivalence for \$1 in 1955 (price index tracking began in 1635).

For example, if you started with \$1, you would need to end with \$1.05 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$1.05 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1955 dollars, the chart below shows how \$1 is worth less over 2 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1955 to 1957 (figures shown are purchasing power equivalents of \$1):

Boston, Massachusetts experienced the highest rate of inflation during the 2 years between 1955 and 1957 (3.13%).

Atlanta, Georgia experienced the lowest rate of inflation during the 2 years between 1955 and 1957 (2.07%).

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 1955 would be equivalent to £1.09 in 1957, an absolute change of £0.09 and a cumulative change of 8.82%.

In Canada, CA\$1.00 in 1955 would be equivalent to CA\$1.05 in 1957, an absolute change of CA\$0.05 and a cumulative change of 4.93%.

Compare these numbers to the US's overall absolute change of \$0.05 and total percent change of 4.85%.

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 1955 and 1957.

Compare these values to the overall average of 2.40% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1955 → 1957
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00

How to Calculate Inflation Rate for \$1, 1955 to 1957

Our calculations use the following inflation rate formula to calculate the change in value between 1955 and 1957:

CPI in 1957 CPI in 1955
×
1955 USD value
=
1957 USD value

Then plug in historical CPI values. The U.S. CPI was 26.8 in the year 1955 and 28.1 in 1957:

28.126.8
×
\$1
=
\$1.05

\$1 in 1955 has the same "purchasing power" or "buying power" as \$1.05 in 1957.

To get the total inflation rate for the 2 years between 1955 and 1957, we use the following formula:

CPI in 1957 - CPI in 1955CPI in 1955
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

28.1 - 26.826.8
×

=
5%

Comparison to S&P 500 Index

The average inflation rate of 2.40% has a compounding effect between 1955 and 1957. As noted above, this yearly inflation rate compounds to produce an overall price difference of 4.85% over 2 years.

To help put this inflation into perspective, if we had invested \$1 in the S&P 500 index in 1955, our investment would be nominally worth approximately \$1.30 in 1957. This is a return on investment of 29.76%, with an absolute return of \$0.30 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 4.63% of returns (\$0.06) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.24. You may also want to account for capital gains tax, which would take your real return down to around \$0 for most people.

Investment in S&P 500 Index, 1955-1957
Original Amount Final Amount Change
Nominal \$1 \$1.30 29.76%
Real
\$1 \$1.24 23.75%

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 1955 to latest available data for 1957 using average monthly close price.

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

• The occupying powers grant full Sovereignty to West Germany.
• The Mainau Declaration against nuclear weapons is signed by 18 Nobel laureates.
• Rosa Parks is arrested in Montgomery, Alabama for refusing to give her seat to a white person and move to the back of the bus.
