$1 in 1908 is equivalent in purchasing power to about $30.06 today, an increase of $29.06 over 113 years. The dollar had an average inflation rate of 3.06% per year between 1908 and today, producing a cumulative price increase of 2,906.40%.

This means that today's prices are 30.06 times higher than average prices since 1908, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 3.33% of what it could buy back then.

The 1908 inflation rate was -2.13%. The current year-over-year inflation rate (2020 to 2021) is now 6.22%^{1}.
If this number holds, $1 today will be equivalent in buying power to $1.06 next year.

This chart shows a calculation of buying power equivalence for $1 in 1908 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $30.06 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $30.06 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 1908 dollars, the chart below shows how $1 is worth less over 113 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:

This conversion table shows various other 1908 amounts in today's dollars, based on the 2,906.40% change in prices:

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1908 would be equivalent to £126.34 in 2021, an absolute change of £125.34 and a cumulative change of 12,534.00%.

Compare these numbers to the US's overall absolute change of $29.06 and total percent change of 2,906.40%.

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 1908 and 2021.

Compare these values to the overall average of 3.06% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1908 → 2021 |
---|---|---|---|

Food and beverages | 3.89 | 7,380.22 | 74.80 |

Housing | 4.17 | 9,994.37 | 100.94 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1908. 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 1908 and today:

$1 in 1908 has the same "purchasing power" or "buying power" as $30.06 in 2021.

To get the total inflation rate for the 113 years between 1908 and 2021, we use the following formula:

CPI in 2021 - CPI in 1908CPI in 1908

Plugging in the values to this equation, we get:

The average inflation rate of 3.06% has a compounding effect between 1908 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,906.40% over 113 years.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1908, our investment would be * nominally* worth approximately $64,991.02 in 2021. This is a return on investment of 6,499,002.50%, with an absolute return of $64,990.02 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 96.67% of returns ($62,829.27) during this period. This means the inflation-adjusted * real* return of our $1 investment is $2,160.75. You may also want to account for capital gains tax, which would take your real return down to around $1,837 for most people.

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

Nominal |
$1 | $64,991.02 | 6,499,002.50% |

RealInflation Adjusted |
$1 | $2,161.75 | 216,075.42% |

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 1908 to latest available data for 2021 using average monthly close price.

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

- "Scouting for Boys", the book that became an inspiration for the Scout Movement, is published by Lieutenant General Robert Baden-Powell
- King Carlos I of Portugal and his heir Prince Luis Filipe in Terreiro do Paco are assassinated.
- A meteor explodes over Siberia with the power of several atomic bombs. This is known as the "Tunguska event".
- The first Model T car is built.

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.
