This chart shows a calculation of buying power equivalence for $425 in 1988 (price index tracking began in 1635).

For example, if you started with $425, you would need to end with $985.48 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $425 is equivalent to $985.48 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 1988 dollars, the chart below shows how $425 is worth less over 33 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:

Note that some locations showing 0% inflation may have not yet reported latest data.

Inflation can also vary widely by country. For comparison, in the UK £425.00 in 1988 would be equivalent to £1,169.03 in 2021, an absolute change of £744.03 and a cumulative change of 175.07%.

In Canada, CA$425.00 in 1988 would be equivalent to CA$807.68 in 2021, an absolute change of CA$382.68 and a cumulative change of 90.04%.

Compare these numbers to the US's overall absolute change of $560.48 and total percent change of 131.88%.

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 1988 and 2021.

Compare these values to the overall average of 2.58% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $425 in 1988 → 2021 |
---|---|---|---|

Food and beverages | 2.58 | 132.02 | 986.08 |

Housing | 2.62 | 135.15 | 999.38 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1988. 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 1988 and today:

Then plug in historical CPI values. The U.S. CPI was 118.3 in the year 1988 and 274.31 in 2021:

$425 in 1988 has the same "purchasing power" or "buying power" as $985.48 in 2021.

To get the total inflation rate for the 33 years between 1988 and 2021, we use the following formula:

CPI in 2021 - CPI in 1988CPI in 1988

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 2.46% per year between 1988 and 2021 (vs all-CPI inflation of 2.58%), for an inflation total of 123.17%.

When using the core inflation measurement, $425 in 1988 is equivalent in buying power to $948.45 in 2021, a difference of $523.45. Recall that for All Items, the converted amount is $985.48 with a difference of $560.48.

In 1988, core inflation was 4.41%.

The average inflation rate of 2.58% has a compounding effect between 1988 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 131.88% over 33 years.

To help put this inflation into perspective, if we had invested $425 in the S&P 500 index in 1988, our investment would be * nominally* worth approximately $15,490.57 in 2021. This is a return on investment of 3,544.84%, with an absolute return of $15,065.57 on top of the original $425.

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 56.87% of returns ($8,810.05) during this period. This means the inflation-adjusted * real* return of our $425 investment is $6,255.53. You may also want to account for capital gains tax, which would take your real return down to around $5,317 for most people.

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

Nominal |
$425 | $15,490.57 | 3,544.84% |

RealInflation Adjusted |
$425 | $6,680.53 | 1,471.89% |

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 1988 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 USSR withdraws its troops from Afghanistan.
- Iran and Iraq announce a ceasefire after 8 years of war.
- Approximately 50,000 Kurdish civilians and soldiers are killed by Iraq.
- Mikhail Gorbachev Chairman becomes president of the USSR.
- Benazir Bhutto becomes the first female leader of a Muslim country in Pakistan.

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.
