U.S. inflation rate in 1947: 14.36%

Inflation in 1947 and its effect on dollar value

$1 in 1946 is equivalent in purchasing power to about $1.14 in 1947. The dollar had an average inflation rate of 14.36% per year between 1946 and 1947, producing a cumulative price increase of 14.36%. Purchasing power decreased by 14.36% in 1947 compared to 1946. On average, you would have to spend 14.36% more money in 1947 than in 1946 for the same item.

This means that prices in 1947 are 1.14 times higher than average prices since 1946, according to the Bureau of Labor Statistics consumer price index.

The 1946 inflation rate was 8.33%. The inflation rate in 1947 was 14.36%. The 1947 inflation rate is higher compared to the average inflation rate of 3.45% per year between 1947 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1947 was 22.30. It was 19.50 in the previous year, 1946. 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 1946 to 1947 (figures shown are purchasing power equivalents of $1):

Houston, Texas experienced the highest rate of inflation during the 1 years between 1946 and 1947 (17.55%).

New York experienced the lowest rate of inflation during the 1 years between 1946 and 1947 (12.01%).

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 1946 would be equivalent to £1.07 in 1947, an absolute change of £0.07 and a cumulative change of 7.04%.

In Canada, CA$1.00 in 1946 would be equivalent to CA$1.14 in 1947, an absolute change of CA$0.14 and a cumulative change of 14.43%.

Compare these numbers to the US's overall absolute change of $0.14 and total percent change of 14.36%.

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 1946 and 1947.

Compare these values to the overall average of 14.36% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1946 → 1947
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 15.90 15.90 1.16
Transportation 9.45 9.45 1.09
Medical care 7.79 7.79 1.08
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1946. This table and charts use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1946 to 1947

Our calculations use the following inflation rate formula to calculate the change in value between 1946 and 1947:

CPI in 1947 CPI in 1946
1946 USD value
1947 USD value

Then plug in historical CPI values. The U.S. CPI was 19.5 in the year 1946 and 22.3 in 1947:


$1 in 1946 has the same "purchasing power" or "buying power" as $1.14 in 1947.

To get the total inflation rate for the 1 years between 1946 and 1947, we use the following formula:

CPI in 1947 - CPI in 1946CPI in 1946
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

22.3 - 19.519.5

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 1946, our investment would be nominally worth approximately $0.90 in 1947. This is a return on investment of -9.80%, with an absolute return of $-0.10 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 12.56% of returns ($0.11) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.21. 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, 1946-1947
Original Amount Final Amount Change
Nominal $1 $0.90 -9.80%
Inflation Adjusted
$1 $0.79 -21.13%

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 1946 to latest available data for 1947 using average monthly close price.

News headlines from 1946

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

  • The United Nations General Assembly meets for the first time in London.
  • President Harry Truman sets up the Central Intelligence Agency or CIA.
  • The US State Department releases the Acheson-Lilenthal Report outlining a plan for how the US can limit nuclear power internationally, marking the beginning of Cold War.
