U.S. inflation rate in 1933: -5.11%

Inflation in 1933 and its effect on dollar value

$1 in 1932 is equivalent in purchasing power to about $0.95 in 1933. The dollar had an average deflation rate of -5.11% per year since 1932, producing a cumulative price change of -5.11%. Purchasing power increased by 5.11% in 1933 compared to 1932. On average, you would have to spend 5.11% less money in 1933 than in 1932 for the same item. This is an example of deflation.

This means that prices in 1933 are 5.11% lower than average prices since 1932, according to the Bureau of Labor Statistics consumer price index.

The inflation rate in 1932 was -9.87%. The inflation rate in 1933 was -5.11%. The 1933 inflation rate is lower compared to the average inflation rate of 3.54% per year between 1933 and 2023.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1933 was 13.00. It was 13.70 in the previous year, 1932. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1933 CPI is less than 1932 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 1932 to 1933 (figures shown are purchasing power equivalents of $1):

San Francisco, California experienced the highest rate of inflation during the 1 years between 1932 and 1933 (-4.94%).

Chicago, Illinois experienced the lowest rate of inflation during the 1 years between 1932 and 1933 (-10.30%).

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 1932 would be equivalent to £0.98 in 1933, an absolute change of £-0.02 and a cumulative change of -2.47%.

In Canada, CA$1.00 in 1932 would be equivalent to CA$0.96 in 1933, an absolute change of CA$-0.04 and a cumulative change of -4.36%.

Compare these numbers to the US's overall absolute change of $-0.05 and total percent change of -5.11%.

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 1932 and 1933.

Compare these values to the overall average of -5.11% per year:

CategoryAvg Inflation (%)Total Inflation (%)$1 in 1932 → 1933

For all these visualizations, it's important to note that not all categories may have been tracked since 1932. This table and charts use the earliest available data for each category.

How to calculate inflation rate for $1, 1932 to 1933

Our calculations use the following inflation rate formula to calculate the change in value between 1932 and 1933:

CPI in 1933 CPI in 1932
1932 USD value
1933 USD value

Then plug in historical CPI values. The U.S. CPI was 13.7 in the year 1932 and 13 in 1933:


$1 in 1932 has the same "purchasing power" or "buying power" as $0.95 in 1933.

To get the total inflation rate for the 1 years between 1932 and 1933, we use the following formula:

CPI in 1933 - CPI in 1932CPI in 1932
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

13 - 13.713.7

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 1932, our investment would be nominally worth approximately $1.48 in 1933. This is a return on investment of 47.64%, with an absolute return of $0.48 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 -5.38% of returns ($-0.08) during this period. This means the inflation-adjusted real return of our $1 investment is $0.56. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

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 1932 to latest available data for 1933 using average monthly close price.
