$1 in 1902 is equivalent in purchasing power to about $1.02 in 1903. The dollar had an average inflation rate of 2.33% per year between 1902 and 1903, producing a cumulative price increase of 2.33%. Purchasing power decreased by 2.33% in 1903 compared to 1902. On average, you would have to spend 2.33% more money in 1903 than in 1902 for the same item.
This means that prices in 1903 are 1.02 times as high as average prices since 1902, according to the Bureau of Labor Statistics consumer price index.
The inflation rate in 1902 was 1.18%. The inflation rate in 1903 was 2.33%. The 1903 inflation rate is lower compared to the average inflation rate of 3.00% per year between 1903 and 2024.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1903 was 8.80. It was 8.60 in the previous year, 1902. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.
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 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%.
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 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 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 1902. This table and charts use the earliest available data for each category.
Our calculations use the following inflation rate formula to calculate the change in value between 1902 and 1903:
Then plug in historical CPI values. The U.S. CPI was 8.6 in the year 1902 and 8.8 in 1903:
$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:
Plugging in the values to this equation, we get:
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 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 2.27% of returns ($0.02) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.12. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.
Original Amount | Final Amount | Change | |
---|---|---|---|
Nominal | $1 | $0.90 | -10.24% |
Real Inflation Adjusted | $1 | $0.88 | -12.28% |
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 1902 to latest available data for 1903 using average monthly close price.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Price index data from 1774 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University and from the American Antiquarian Society. Price index data from 1634 to 1773 is from the American Antiquarian Society, using British pound equivalents.
