Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1925 to 1934 (figures shown are purchasing power equivalents of $1):

San Francisco, California experienced the highest rate of inflation during the 9 years between 1925 and 1934 (-2.26%).

Detroit, Michigan experienced the lowest rate of inflation during the 9 years between 1925 and 1934 (-3.99%).

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 1925 would be equivalent to £0.85 in 1934, an absolute change of £-0.15 and a cumulative change of -15.05%.

In Canada, CA$1.00 in 1925 would be equivalent to CA$0.79 in 1934, an absolute change of CA$-0.21 and a cumulative change of -20.99%.

Compare these numbers to the US's overall absolute change of $-0.23 and total percent change of -23.43%.


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 1925 and 1934.

Compare these values to the overall average of -2.92% per year:

How to calculate inflation rate for $1, 1925 to 1934

Our calculations use the following inflation rate formula to calculate the change in value between 1925 and 1934:

CPI in 1934 CPI in 1925
×
1925 USD value
=
1934 USD value

Then plug in historical CPI values. The U.S. CPI was 17.5 in the year 1925 and 13.4 in 1934:

13.417.5
×
$1
=
$0.77

$1 in 1925 has the same "purchasing power" or "buying power" as $0.77 in 1934.

To get the total inflation rate for the 9 years between 1925 and 1934, we use the following formula:

CPI in 1934 - CPI in 1925CPI in 1925
×
100
=
Cumulative inflation rate (9 years)

Plugging in the values to this equation, we get:

13.4 - 17.517.5
×
100
=
-23%

Comparison to S&P 500 Index

The average inflation rate of -2.92% has a compounding effect between 1925 and 1934. As noted above, this yearly inflation rate compounds to produce an overall price difference of -23.43% over 9 years.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1925, our investment would be nominally worth approximately $1.51 in 1934. This is a return on investment of 50.50%, with an absolute return of $0.51 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 -30.60% of returns ($-0.46) during this period. This means the inflation-adjusted real return of our $1 investment is $0.97. You may also want to account for capital gains tax, which would take your real return down to around $1 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 1925 to latest available data for 1934 using average monthly close price.
