U.S. inflation rate in 1942: 10.88%

Inflation in 1942 and its effect on dollar value

$1 in 1941 is equivalent in purchasing power to about $1.11 in 1942. The dollar had an average inflation rate of 10.88% per year between 1941 and 1942, producing a cumulative price increase of 10.88%. Purchasing power decreased by 10.88% in 1942 compared to 1941. On average, you would have to spend 10.88% more money in 1942 than in 1941 for the same item.

This means that prices in 1942 are 1.11 times higher than average prices since 1941, according to the Bureau of Labor Statistics consumer price index.

The 1941 inflation rate was 5.00%. The inflation rate in 1942 was 10.88%. The 1942 inflation rate is higher compared to the average inflation rate of 3.63% per year between 1942 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1942 was 16.30. It was 14.70 in the previous year, 1941. 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 1941 to 1942 (figures shown are purchasing power equivalents of $1):

Seattle, Washington experienced the highest rate of inflation during the 1 years between 1941 and 1942 (12.43%).

New York experienced the lowest rate of inflation during the 1 years between 1941 and 1942 (9.62%).

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 1941 would be equivalent to £1.07 in 1942, an absolute change of £0.07 and a cumulative change of 7.14%.

In Canada, CA$1.00 in 1941 would be equivalent to CA$1.03 in 1942, an absolute change of CA$0.03 and a cumulative change of 3.45%.

Compare these numbers to the US's overall absolute change of $0.11 and total percent change of 10.88%.

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 1941 and 1942.

Compare these values to the overall average of 10.88% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1941 → 1942
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 17.03 17.03 1.17
Transportation 8.54 8.54 1.09
Medical care 3.07 3.07 1.03
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 1941. This table and charts use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1941 to 1942

Our calculations use the following inflation rate formula to calculate the change in value between 1941 and 1942:

CPI in 1942 CPI in 1941
1941 USD value
1942 USD value

Then plug in historical CPI values. The U.S. CPI was 14.7 in the year 1941 and 16.3 in 1942:


$1 in 1941 has the same "purchasing power" or "buying power" as $1.11 in 1942.

To get the total inflation rate for the 1 years between 1941 and 1942, we use the following formula:

CPI in 1942 - CPI in 1941CPI in 1941
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

16.3 - 14.714.7

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 1941, our investment would be nominally worth approximately $1.11 in 1942. This is a return on investment of 10.67%, with an absolute return of $0.11 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 9.82% of returns ($0.11) during this period. This means the inflation-adjusted real return of our $1 investment is $0.00. 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, 1941-1942
Original Amount Final Amount Change
Nominal $1 $1.11 10.67%
Inflation Adjusted
$1 $1.00 -0.19%

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 1941 to latest available data for 1942 using average monthly close price.

News headlines from 1941

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

  • 6,000 Jews are exterminated in the Bucharest pogrom in Romania.
  • Kuomintang troops open fire at communist forces, leading to the resumption of the Chinese civil war.
  • The British battle cruiser the HMS Hood is sunk by the German Battleship Bismarck, leading to 1,416 dead and only 3 survivors.
  • Germany, Italy, and Romania declare war on the Soviet Union.
