Inflation in 1903 and Its Effect on Dollar Value

Purchasing power decreased by 2.33% in 1903 compared to the previous year, 1902. On average, you would have to spend 2.33% more money in 1903 than in 1902 for the same item.

In other words, $1 in 1902 is equivalent in purchasing power to $1.02 in 1903.

The 1902 inflation rate was 1.18%. The inflation rate in 1903 was 2.33%. The 1903 inflation rate is lower compared to the average inflation rate of 2.96% per year between 1903 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1903 was 8.8. It was 8.6 in the previous year, 1902. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.


Inflation from 1902 to 1903
Average inflation rate 2.33%
Converted amount ($1 base) $1.02
Price difference ($1 base) $0.02
CPI in 1902 8.600
CPI in 1903 8.800
Inflation in 1902 1.18%
Inflation in 1903 2.33%

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1902 would be equivalent to £1.01 in 1903, an absolute change of £0.01 and a cumulative change of 1.09%.

Compare these numbers to the US's overall absolute change of $0.02 and total percent change of 2.33%.


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 1902 and 1903.

Compare these values to the overall average of 2.33% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1902 → 1903
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 0.00 0.00 1.00
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1902. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $1, 1902 to 1903

This inflation calculator uses the following inflation rate formula:

CPI in 1903CPI in 1902
×
1902 USD value
=
1903 USD value

Then plug in historical CPI values. The U.S. CPI was 8.6 in the year 1902 and 8.8 in 1903:

8.88.6
×
$1
=
$1.02

$1 in 1902 has the same "purchasing power" or "buying power" as $1.02 in 1903.

To get the total inflation rate for the 1 years between 1902 and 1903, we use the following formula:

CPI in 1903 - CPI in 1902CPI in 1902
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.8 - 8.68.6
×
100
=
2%

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 1902, our investment would be nominally worth approximately $0.90 in 1903. This is a return on investment of -10.24%, with an absolute return of $-0.10.

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 2.27% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.10.

Investment in S&P 500 Index, 1902-1903
Original Amount Final Amount Change
Nominal $1 $0.90 -10.24%
Real
Inflation Adjusted
$1 $-0.10 -10.01%
