Inflation in 1928 and Its Effect on Dollar Value

Purchasing power increased by 1.72% in 1928 compared to the previous year, 1927. On average, you would have to spend 1.72% less money in 1928 than in 1927 for the same item. This is an example of deflation.

In other words, $100 in 1927 is equivalent in purchasing power to $98.28 in 1928.

The 1927 inflation rate was -1.69%. The inflation rate in 1928 was -1.72%. The 1928 inflation rate is lower compared to the average inflation rate of 3.04% per year between 1928 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1928 was 17.1. It was 17.4 in the previous year, 1927. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1928 CPI is less than 1927 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 1927 to 1928 (figures shown are purchasing power equivalents of $100):

San Francisco, California experienced the highest rate of inflation during the 1 years between 1927 and 1928 (-0.89%).

Detroit, Michigan experienced the lowest rate of inflation during the 1 years between 1927 and 1928 (-3.49%).


Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1927 would be equivalent to £100.00 in 1928, an absolute change of £0.00 and a cumulative change of 0.00%.

In Canada, CA$100.00 in 1927 would be equivalent to CA$101.10 in 1928, an absolute change of CA$1.10 and a cumulative change of 1.10%.

Compare these numbers to the US's overall absolute change of $-1.72 and total percent change of -1.72%.


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 1927 and 1928.

Compare these values to the overall average of -1.72% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1927 → 1928
Food -1.12 -1.12 98.88
Shelter 0.00 0.00 100.00
Energy 0.00 0.00 100.00
Apparel -1.19 -1.19 98.81
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 1927. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1927 to 1928

This inflation calculator uses the following inflation rate formula:

CPI in 1928CPI in 1927
×
1927 USD value
=
1928 USD value

Then plug in historical CPI values. The U.S. CPI was 17.4 in the year 1927 and 17.1 in 1928:

17.117.4
×
$100
=
$98.28

$100 in 1927 has the same "purchasing power" or "buying power" as $98.28 in 1928.

To get the total inflation rate for the 1 years between 1927 and 1928, we use the following formula:

CPI in 1928 - CPI in 1927CPI in 1927
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

17.1 - 17.417.4

=
-2%
