Inflation in 1945 and Its Effect on Dollar Value

Purchasing power decreased by 2.27% in 1945 compared to 1944. On average, you would have to spend 2.27% more money in 1945 than in 1944 for the same item.

In other words, $1 in 1944 is equivalent in purchasing power to about $1.02 in 1945.

The 1944 inflation rate was 1.73%. The inflation rate in 1945 was 2.27%. The 1945 inflation rate is lower compared to the average inflation rate of 3.64% per year between 1945 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1945 was 18.00. It was 17.60 in the previous year, 1944. 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 1944 to 1945 (figures shown are purchasing power equivalents of $1):

Atlanta, Georgia experienced the highest rate of inflation during the 1 years between 1944 and 1945 (3.52%).

Boston, Massachusetts experienced the lowest rate of inflation during the 1 years between 1944 and 1945 (2.04%).

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 1944 would be equivalent to £1.03 in 1945, an absolute change of £0.03 and a cumulative change of 2.75%.

In Canada, CA$1.00 in 1944 would be equivalent to CA$1.02 in 1945, an absolute change of CA$0.02 and a cumulative change of 2.22%.

Compare these numbers to the US's overall absolute change of $0.02 and total percent change of 2.27%.

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 1944 and 1945.

Compare these values to the overall average of 2.27% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1944 → 1945
Food 2.28 2.28 1.02
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 5.16 5.16 1.05
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 2.70 2.70 1.03
Medical care commodities 0.90 0.90 1.01

It's important to note that not all categories may be tracked since 1944. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1944 to 1945

This inflation calculator uses the following inflation rate formula:

CPI in 1945CPI in 1944
1944 USD value
1945 USD value

Then plug in historical CPI values. The U.S. CPI was 17.6 in the year 1944 and 18 in 1945:


$1 in 1944 has the same "purchasing power" or "buying power" as $1.02 in 1945.

To get the total inflation rate for the 1 years between 1944 and 1945, we use the following formula:

CPI in 1945 - CPI in 1944CPI in 1944
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

18 - 17.617.6

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 1944, our investment would be nominally worth approximately $1.67 in 1945. This is a return on investment of 66.75%, with an absolute return of $0.67.

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 2.22% of returns ($0.01) during this period. This means the inflation-adjusted real return of our $1 investment is $0.65.

Investment in S&P 500 Index, 1944-1945
Original Amount Final Amount Change
Nominal $1 $1.67 66.75%
Inflation Adjusted
$1 $0.65 65.27%

News headlines from 1944
