$1 in 1905 is equivalent in purchasing power to about $1.02 in 1906. The dollar had an average inflation rate of 2.27% per year between 1905 and 1906, producing a cumulative price increase of 2.27%. Purchasing power decreased by 2.27% in 1906 compared to 1905. On average, you would have to spend 2.27% more money in 1906 than in 1905 for the same item.

This means that prices in 1906 are 1.02 times higher than average prices since 1905, according to the Bureau of Labor Statistics consumer price index.

The 1905 inflation rate was -1.12%. The inflation rate in 1906 was 2.27%. The 1906 inflation rate is lower compared to the average inflation rate of 3.02% per year between 1906 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1906 was 9.00. It was 8.80 in the previous year, 1905. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1905 would be equivalent to £1.00 in 1906, an absolute change of £0.00 and a cumulative change of 0.00%.

Compare these numbers to the US's overall absolute change of $0.02 and total percent change of 2.27%.

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 1905 and 1906.

Compare these values to the overall average of 2.27% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1905 → 1906 |
---|---|---|---|

Food and beverages | 0.00 | 0.00 | 1.00 |

Housing | 0.00 | 0.00 | 1.00 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1905. 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 1905 and 1906:

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1905 and 9 in 1906:

$1 in 1905 has the same "purchasing power" or "buying power" as $1.02 in 1906.

To get the total inflation rate for the 1 years between 1905 and 1906, we use the following formula:

CPI in 1906 - CPI in 1905CPI in 1905

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 1905, our investment would be * nominally* worth approximately $1.22 in 1906. This is a return on investment of 22.06%, with an absolute return of $0.22 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 2.22% of returns ($0.03) during this period. This means the inflation-adjusted * real* return of our $1 investment is $0.19. 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 | $1.22 | 22.06% |

RealInflation Adjusted |
$1 | $1.19 | 19.34% |

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 1905 to latest available data for 1906 using average monthly close price.

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

- The Industrial Workers of the World is formed. It is an American anarcho-syndicalist union.
- Bloody Sunday in Russia: troops fire and kill protesters, mostly workers, marching to the Winter Palace in order to hand a petition to the Tsar.
- Potemkin's arrival at Odessa leads to sailors joining civilians in the '1905 Revolution’.

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (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.
