Inflation Calculator


Inflation in 1949 and Its Effect on Dollar Value

Purchasing power increased by 1.24% in 1949 compared to the previous year, 1948. On average, you would have to spend 1.24% less money in 1949 than in 1948 for the same item. This is an example of deflation.

In other words, $1 in 1948 is equivalent in purchasing power to $0.99 in 1949.

The 1948 inflation rate was 8.07%. The inflation rate in 1949 was -1.24%. The 1949 inflation rate is lower compared to the average inflation rate of 3.48% per year between 1949 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1949 was 23.8. It was 24.1 in the previous year, 1948. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1949 CPI is less than 1948 CPI, negative inflation (also known as deflation) has occurred.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1948 to 1949 (figures shown are purchasing power equivalents of $1):

San Francisco, California experienced the highest rate of inflation during the 1 years between 1948 and 1949 (0.38%).

Detroit, Michigan experienced the lowest rate of inflation during the 1 years between 1948 and 1949 (-1.29%).

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 1948 would be equivalent to £1.03 in 1949, an absolute change of £0.03 and a cumulative change of 2.89%.

In Canada, CA$1.00 in 1948 would be equivalent to CA$1.01 in 1949, an absolute change of CA$0.01 and a cumulative change of 0.83%.

Compare these numbers to the US's overall absolute change of $-0.01 and total percent change of -1.24%.

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 1948 and 1949.

Compare these values to the overall average of -1.24% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1948 → 1949
Food -3.92 -3.92 0.96
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel -3.94 -3.94 0.96
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 3.29 3.29 1.03
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1948. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1948 to 1949

This inflation calculator uses the following inflation rate formula:

CPI in 1949CPI in 1948
1948 USD value
1949 USD value

Then plug in historical CPI values. The U.S. CPI was 24.1 in the year 1948 and 23.8 in 1949:


$1 in 1948 has the same "purchasing power" or "buying power" as $0.99 in 1949.

To get the total inflation rate for the 1 years between 1948 and 1949, we use the following formula:

CPI in 1949 - CPI in 1948CPI in 1948
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

23.8 - 24.124.1

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 1948, our investment would be nominally worth approximately $1.29 in 1949. This is a return on investment of 28.65%, with an absolute return of $0.29.

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 -1.26% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $0.29.

Investment in S&P 500 Index, 1948-1949
Original Amount Final Amount Change
Nominal $1 $1.29 28.65%
Inflation Adjusted
$1 $0.29 29.01%
