\$1 in 1945 is worth \$1.34 in 1948

\$

Value of \$1 from 1945 to 1948

According to the Bureau of Labor Statistics consumer price index, prices in 1948 are 33.89% higher than average prices since 1945. The U.S. dollar experienced an average inflation rate of 10.22% per year during this period, causing the real value of a dollar to decrease.

In other words, \$1 in 1945 is equivalent in purchasing power to about \$1.34 in 1948, a difference of \$0.34 over 3 years.

The 1945 inflation rate was 2.27%. The inflation rate in 1948 was 8.07%. The 1948 inflation rate is higher compared to the average inflation rate of 3.34% per year between 1948 and 2020.

Buying power of \$1 in 1945

This chart shows a calculation of buying power equivalence for \$1 in 1945 (price index tracking began in 1635).

For example, if you started with \$1, you would need to end with \$1.34 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$1 is equivalent to \$1.34 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 1945 dollars, the chart below shows how \$1 is worth less over 3 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 1945 to 1948 (figures shown are purchasing power equivalents of \$1):

Chicago, Illinois experienced the highest rate of inflation during the 3 years between 1945 and 1948 (11.21%).

San Francisco, California experienced the lowest rate of inflation during the 3 years between 1945 and 1948 (9.30%).

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 1945 would be equivalent to £1.19 in 1948, an absolute change of £0.19 and a cumulative change of 18.70%.

In Canada, CA\$1.00 in 1945 would be equivalent to CA\$1.32 in 1948, an absolute change of CA\$0.32 and a cumulative change of 31.52%.

Compare these numbers to the US's overall absolute change of \$0.34 and total percent change of 33.89%.

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 1945 and 1948.

Compare these values to the overall average of 10.22% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1945 → 1948
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 10.69 35.61 1.36

How to Calculate Inflation Rate for \$1, 1945 to 1948

Our calculations use the following inflation rate formula to calculate the change in value between 1945 and 1948:

CPI in 1948 CPI in 1945
×
1945 USD value
=
1948 USD value

Then plug in historical CPI values. The U.S. CPI was 18 in the year 1945 and 24.1 in 1948:

24.118
×
\$1
=
\$1.34

\$1 in 1945 has the same "purchasing power" or "buying power" as \$1.34 in 1948.

To get the total inflation rate for the 3 years between 1945 and 1948, we use the following formula:

CPI in 1948 - CPI in 1945CPI in 1945
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

24.1 - 1818
×
100
=
34%

Comparison to S&P 500 Index

The average inflation rate of 10.22% has a compounding effect between 1945 and 1948. As noted above, this yearly inflation rate compounds to produce an overall price difference of 33.89% over 3 years.

To help put this inflation into perspective, if we had invested \$1 in the S&P 500 index in 1945, our investment would be nominally worth approximately \$1.38 in 1948. This is a return on investment of 37.64%, with an absolute return of \$0.38 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 25.31% of returns (\$0.35) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.03. 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, 1945-1948
Original Amount Final Amount Change
Nominal \$1 \$1.38 37.64%
Real
Inflation Adjusted
\$1 \$1.03 2.80%

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 1945 to latest available data for 1948 using average monthly close price.
