This chart shows a calculation of buying power equivalence for $340,000 in 1925 (price index tracking began in 1635).

For example, if you started with $340,000, you would need to end with $5,315,016 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $340,000 is equivalent to $5,315,016 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 1925 dollars, the chart below shows how $340,000 is worth less over 96 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 £340,000.00 in 1925 would be equivalent to £21,203,404.24 in 2021, an absolute change of £20,863,404.24 and a cumulative change of 6,136.30%.

In Canada, CA$340,000.00 in 1925 would be equivalent to CA$5,023,225.81 in 2021, an absolute change of CA$4,683,225.81 and a cumulative change of 1,377.42%.

Compare these numbers to the US's overall absolute change of $4,975,016.00 and total percent change of 1,463.24%.

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 1925 and 2021.

Compare these values to the overall average of 2.91% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $340,000 in 1925 → 2021 |

Our calculations use the following inflation rate formula to calculate the change in value between 1925 and today:

Then plug in historical CPI values. The U.S. CPI was 17.5 in the year 1925 and 273.567 in 2021:

$340,000 in 1925 has the same "purchasing power" or "buying power" as $5,315,016 in 2021.

To get the total inflation rate for the 96 years between 1925 and 2021, we use the following formula:

The average inflation rate of 2.91% has a compounding effect between 1925 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 1,463.24% over 96 years.

To help put this inflation into perspective, if we had invested $340,000 in the S&P 500 index in 1925, our investment would be * nominally* worth approximately $5,278,273,373.97 in 2021. This is a return on investment of 1,552,333.35%, with an absolute return of $5,277,933,373.97 on top of the original $340,000.

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 93.60% of returns ($4,940,623,788.88) during this period. This means the inflation-adjusted * real* return of our $340,000 investment is $337,309,585.09. You may also want to account for capital gains tax, which would take your real return down to around $286,713,147 for most people.

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

Nominal |
$340,000 | $5,278,273,373.97 | 1,552,333.35% |

RealInflation Adjusted |
$340,000 | $337,649,585.09 | 99,208.70% |

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 1925 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:

- Mein Kampf is published by Adolf Hitler.
- The Ku Klux Klan's first national march takes place in Washington.
- The last Qajar Shah of Iran is deposed with Reza Shah Pahlavi taking over.
- Scopes monkey trial ends in Dayton, Tennessee, finding John T. Scopes guilty of teaching evolution.

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.
