This chart shows a calculation of buying power equivalence for $381,100,000 in 1985 (price index tracking began in 1635).

For example, if you started with $381,100,000, you would need to end with $971,557,072.49 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $381,100,000 is equivalent to $971,557,072.49 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 1985 dollars, the chart below shows how $381,100,000 is worth less over 36 years.

Inflation can also vary widely by country. For comparison, in the UK £381,100,000.00 in 1985 would be equivalent to £1,184,505,097.73 in 2021, an absolute change of £803,405,097.73 and a cumulative change of 210.81%.

In Canada, CA$381,100,000.00 in 1985 would be equivalent to CA$816,897,659.91 in 2021, an absolute change of CA$435,797,659.91 and a cumulative change of 114.35%.

Compare these numbers to the US's overall absolute change of $590,457,072.49 and total percent change of 154.93%.

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 1985 and 2021.

Compare these values to the overall average of 2.63% per year:

$381,100,000 in 1985 has the same "purchasing power" or "buying power" as $971,557,072.49 in 2021.

To get the total inflation rate for the 36 years between 1985 and 2021, we use the following formula:

The above data describe the CPI for all items. Also of note is the **Core CPI**, which measures inflation for all items except for the more volatile categories of food and energy.
Core inflation averaged 2.61% per year between 1985 and 2021 (vs all-CPI inflation of 2.63%), for an inflation total of 152.41%.

When using the core inflation measurement, $381,100,000 in 1985 is equivalent in buying power to $961,940,998.24 in 2021, a difference of $580,840,998.24. Recall that for All Items, the converted amount is $971,557,072.49 with a difference of $590,457,072.49.

In 1985, core inflation was 4.37%.

The average inflation rate of 2.63% has a compounding effect between 1985 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 154.93% over 36 years.

To help put this inflation into perspective, if we had invested $381,100,000 in the S&P 500 index in 1985, our investment would be * nominally* worth approximately $22,515,567,845.63 in 2021. This is a return on investment of 5,808.05%, with an absolute return of $22,134,467,845.63 on top of the original $381,100,000.

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 60.77% of returns ($13,683,680,199.57) during this period. This means the inflation-adjusted * real* return of our $381,100,000 investment is $8,450,787,646.06. You may also want to account for capital gains tax, which would take your real return down to around $7,183,169,499 for most people.

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

Nominal |
$381,100,000 | $22,515,567,845.63 | 5,808.05% |

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 1985 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:

- Mikhail Gorbachev replaces Konstantin Chernenko as leader of the Soviet Union.
- Earthquake with a magnitude of 8.1 rocks Mexico City and kills 10,000 people, leaving over 250,000 homeless.
- Mikhail Gorbachev (leader of the Soviet Union) and Ronald Reagan (President of the United States) meet for the first time.
- Ernie Wise makes the first mobile phone call in the UK.

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.
