Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1928 to 1929 (figures shown are purchasing power equivalents of $100):

Seattle, Washington experienced the highest rate of inflation during the 1 years between 1928 and 1929 (0.71%).

Philadelphia, Pennsylvania experienced the lowest rate of inflation during the 1 years between 1928 and 1929 (-1.93%).


Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1928 would be equivalent to £98.89 in 1929, an absolute change of £-1.11 and a cumulative change of -1.11%.

In Canada, CA$100.00 in 1928 would be equivalent to CA$102.17 in 1929, an absolute change of CA$2.17 and a cumulative change of 2.17%.

Compare these numbers to the US's overall absolute change of $0.00 and total percent change of 0.00%.


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 1928 and 1929.

Compare these values to the overall average of 0.00% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1928 → 1929
Food 1.28 1.28 101.28
Shelter 0.00 0.00 100.00
Energy 0.00 0.00 100.00
Apparel -1.20 -1.20 98.80
New vehicles 0.00 0.00 100.00
Used cars and trucks 0.00 0.00 100.00
Transportation services 0.00 0.00 100.00
Medical care services 0.00 0.00 100.00
Medical care commodities 0.00 0.00 100.00

It's important to note that not all categories may be tracked since 1928. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1928 to 1929

This inflation calculator uses the following inflation rate formula:

CPI in 1929CPI in 1928
×
1928 USD value
=
1929 USD value

Then plug in historical CPI values. The U.S. CPI was 17.1 in the year 1928 and 17.1 in 1929:

17.117.1
×
$100
=
$100

$100 in 1928 has the same "purchasing power" or "buying power" as $100 in 1929.

To get the total inflation rate for the 1 years between 1928 and 1929, we use the following formula:

CPI in 1929 - CPI in 1928CPI in 1928
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

17.1 - 17.117.1
×
100
=
0%

Comparison to S&P 500 Index

To help put this inflation into perspective, if you had invested $100 in the S&P 500 index in 1928, your investment would be worth approximately $133.61 in 1929. This is a change of 33.61%.

This means the nominal return on a $100 investment is $33.61, but inflation would eat into your real returns.

Inflation would account for 0.00% of your returns ($0.00), for an inflation-adjusted real return of about $33.61.
