# U.S. inflation rate in 1904: 1.14%

## Inflation in 1904 and its effect on dollar value

Purchasing power decreased by 1.14% in 1904 compared to 1903. On average, you would have to spend 1.14% more money in 1904 than in 1903 for the same item.

In other words, \$1 in 1903 is equivalent in purchasing power to about \$1.01 in 1904.

The 1903 inflation rate was 2.33%. The inflation rate in 1904 was 1.14%. The 1904 inflation rate is lower compared to the average inflation rate of 2.94% per year between 1904 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1904 was 8.90. It was 8.80 in the previous year, 1903. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

## Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1903 would be equivalent to £1.00 in 1904, an absolute change of £0.00 and a cumulative change of 0.00%.

Compare these numbers to the US's overall absolute change of \$0.01 and total percent change of 1.14%.

## 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 1903 and 1904.

Compare these values to the overall average of 1.14% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1903 → 1904
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1903. This table and charts use the earliest available data for each category.

## How to Calculate Inflation Rate for \$1, 1903 to 1904

Our calculations use the following inflation rate formula to calculate the change in value between 1903 and 1904:

CPI in 1904 CPI in 1903
×
1903 USD value
=
1904 USD value

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1903 and 8.9 in 1904:

8.98.8
×
\$1
=
\$1.01

\$1 in 1903 has the same "purchasing power" or "buying power" as \$1.01 in 1904.

To get the total inflation rate for the 1 years between 1903 and 1904, we use the following formula:

CPI in 1904 - CPI in 1903CPI in 1903
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.9 - 8.88.8
×
100
=
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 1903, our investment would be nominally worth approximately \$1.10 in 1904. This is a return on investment of 9.56%, with an absolute return of \$0.10 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 1.12% of returns (\$0.01) during this period. This means the inflation-adjusted real return of our \$1 investment is \$0.08. You may also want to account for capital gains tax, which would take your real return down to around \$0 for most people.

Investment in S&P 500 Index, 1903-1904
Original Amount Final Amount Change
Nominal \$1 \$1.10 9.56%
Real
\$1 \$1.08 8.32%

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 1903 to latest available data for 1904 using average monthly close price.

Politics and news often influence economic performance. Here's what was happening at the time:

• The British gain control over 500,000 square miles of Nigerian land after the fall of the Sokoto Caliphate.
• The typhoid vaccine is discovered by Doctor Harry Plotz.
• The Pulitzer Prizes are established after Joe Pulitzer's \$1 million donation to Columbia University.

## Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
