This chart shows a calculation of buying power equivalence for $100 in 1905 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $2,727.35 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $2,727.35 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1905 dollars, the chart below shows how $100 is worth less over 111 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1905 would be equivalent to £11,158.06 in 2016, an absolute change of £11,058.06 and a cumulative change of 11,058.06%.

Compare these numbers to the US's overall absolute change of $2,627.35 and total percent change of 2,627.35%.

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 2016.

Compare these values to the overall average of 3.02% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $100 in 1905 → 2016 |

Food and beverages | 4.07 | 8,318.78 | 8,418.78 |

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 2016:

CPI in 2016

2016 USD value

Then plug in historical CPI values. The U.S. CPI was 8.8 in the year 1905 and 240.007 in 2016:

$100 in 1905 has the same "purchasing power" or "buying power" as $2,727.35 in 2016.

To get the total inflation rate for the 111 years between 1905 and 2016, we use the following formula:

CPI in 2016 - CPI in 1905CPI in 1905

Plugging in the values to this equation, we get:

The average inflation rate of 3.02% has a compounding effect between 1905 and 2016. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,627.35% over 111 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 1905, our investment would be * nominally* worth approximately $2,803,935.63 in 2016. This is a return on investment of 2,803,835.63%, with an absolute return of $2,803,835.63 on top of the original $100.

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 96.33% of returns ($2,701,127.65) during this period. This means the inflation-adjusted * real* return of our $100 investment is $102,707.97. You may also want to account for capital gains tax, which would take your real return down to around $87,302 for most people.

Original Amount | Final Amount | Change | |
---|---|---|---|

Nominal |
$100 | $2,803,935.63 | 2,803,835.63% |

RealInflation Adjusted |
$100 | $102,807.97 | 102,707.97% |

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 2016 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.
