This chart shows a calculation of buying power equivalence for $260,000 in 1920 (price index tracking began in 1635).

For example, if you started with $260,000, you would need to end with $4,098,913.00 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $260,000 is equivalent to $4,098,913.00 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 $260,000 is worth less over 104 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 £260,000.00 in 1920 would be equivalent to £14,563,455.75 in 2024, an absolute change of £14,303,455.75 and a cumulative change of 5,501.33%.

Compare these numbers to the US's overall absolute change of $3,838,913.00 and total percent change of 1,476.51%.

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 2024.

Compare these values to the overall average of 2.69% per year:

The average inflation rate of 2.69% has a compounding effect between 1920 and 2024. As noted above, this yearly inflation rate compounds to produce an overall price difference of 1,476.51% over 104 years.

To help put this inflation into perspective, if we had invested $260,000 in the S&P 500 index in 1920, our investment would be * nominally* worth approximately $8,475,226,128.90 in 2024. This is a return on investment of 3,259,602.36%, with an absolute return of $8,474,966,128.90 on top of the original $260,000.

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 93.66% of returns ($7,937,630,236.16) during this period. This means the inflation-adjusted * real* return of our $260,000 investment is $537,335,892.74. You may also want to account for capital gains tax, which would take your real return down to around $456,735,509 for most people.

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

Nominal | $260,000 | $8,475,226,128.90 | 3,259,602.36% |

RealInflation Adjusted | $260,000 | $537,595,892.74 | 206,667.65% |

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 2024 using average monthly close price.
