This chart shows a calculation of buying power equivalence for $5,400 in 1920 (price index tracking began in 1635).

For example, if you started with $5,400, you would need to end with $73,863.09 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $5,400 is equivalent to $73,863.09 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 1920 dollars, the chart below shows how $5,400 is worth less over 101 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 £5,400.00 in 1920 would be equivalent to £247,578.46 in 2021, an absolute change of £242,178.46 and a cumulative change of 4,484.79%.

Compare these numbers to the US's overall absolute change of $68,463.09 and total percent change of 1,267.84%.

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 1920 and 2021.

Compare these values to the overall average of 2.62% per year:

$5,400 in 1920 has the same "purchasing power" or "buying power" as $73,863.09 in 2021.

To get the total inflation rate for the 101 years between 1920 and 2021, we use the following formula:

The average inflation rate of 2.62% has a compounding effect between 1920 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 1,267.84% over 101 years.

To help put this inflation into perspective, if we had invested $5,400 in the S&P 500 index in 1920, our investment would be * nominally* worth approximately $137,401,354.34 in 2021. This is a return on investment of 2,544,369.52%, with an absolute return of $137,395,954.34 on top of the original $5,400.

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 92.69% of returns ($127,356,184.10) during this period. This means the inflation-adjusted * real* return of our $5,400 investment is $10,039,770.24. You may also want to account for capital gains tax, which would take your real return down to around $8,533,805 for most people.

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

Nominal |
$5,400 | $137,401,354.34 | 2,544,369.52% |

RealInflation Adjusted |
$5,400 | $10,045,170.24 | 185,921.67% |

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 1920 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:

- The League of Nations' first assembly takes place in Paris.
- The British Parliament passes the Fourth Home Rule Act, dividing Ireland into two parts and leading to a yearlong Anglo-Irish war in the southern counties.
- The Catholic Church canonizes Joan of Arc, formally making her a saint.
- The 19th Amendment to the constitution is ratified, granting U.S. woman suffrage for the first time.

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.
