This chart shows a calculation of buying power equivalence for $1 in 1980 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $3.14 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $3.14 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 1980 dollars, the chart below shows how $1 is worth less over 40 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 vary widely by city, even within the United States. Here's how some cities fared in 1980 to 2020 (figures shown are purchasing power equivalents of $1):

**San Francisco, California**: 3.36% average rate, $1 → $3.74, cumulative change of 274.47%**Boston, Massachusetts**: 3.15% average rate, $1 → $3.46, cumulative change of 245.82%**New York**: 3.14% average rate, $1 → $3.45, cumulative change of 244.81%**Seattle, Washington**: 3.13% average rate, $1 → $3.43, cumulative change of 243.15%**Miami-Fort Lauderdale, Florida**: 3.08% average rate, $1 → $3.37, cumulative change of 236.79%**Philadelphia, Pennsylvania**: 2.87% average rate, $1 → $3.10, cumulative change of 209.62%**Atlanta, Georgia**: 2.86% average rate, $1 → $3.09, cumulative change of 208.56%**Chicago, Illinois**: 2.76% average rate, $1 → $2.97, cumulative change of 196.77%**Dallas-Fort Worth, Texas**: 2.74% average rate, $1 → $2.95, cumulative change of 195.20%**Detroit, Michigan**: 2.59% average rate, $1 → $2.79, cumulative change of 178.56%**Houston, Texas**: 2.59% average rate, $1 → $2.78, cumulative change of 177.89%

San Francisco, California experienced the highest rate of inflation during the 40 years between 1980 and 2020 (3.36%).

Houston, Texas experienced the lowest rate of inflation during the 40 years between 1980 and 2020 (2.59%).

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 £1.00 in 1980 would be equivalent to £4.37 in 2020, an absolute change of £3.37 and a cumulative change of 336.82%.

In Canada, CA$1.00 in 1980 would be equivalent to CA$2.95 in 2020, an absolute change of CA$1.95 and a cumulative change of 195.24%.

Compare these numbers to the US's overall absolute change of $2.14 and total percent change of 214.09%.

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 1980 and 2020.

Compare these values to the overall average of 2.90% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1980 → 2020 |
---|---|---|---|

Food and beverages | 2.85 | 207.35 | 3.07 |

Housing | 3.07 | 235.35 | 3.35 |

Apparel | 0.66 | 29.84 | 1.30 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1980. 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 1980 and 2020:

Then plug in historical CPI values. The U.S. CPI was 82.4 in the year 1980 and 258.81166666667 in 2020:

$1 in 1980 has the same "purchasing power" or "buying power" as $3.14 in 2020.

To get the total inflation rate for the 40 years between 1980 and 2020, 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 3.04% per year between 1980 and 2020 (vs all-CPI inflation of 2.90%), for an inflation total of 231.37%.

When using the core inflation measurement, $1 in 1980 is equivalent in buying power to $3.31 in 2020, a difference of $2.31. Recall that for All Items, the converted amount is $3.14 with a difference of $2.14.

In 1980, core inflation was 12.42%.

The average inflation rate of 2.90% has a compounding effect between 1980 and 2020. As noted above, this yearly inflation rate compounds to produce an overall price difference of 214.09% over 40 years.

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1980, our investment would be * nominally* worth approximately $97.89 in 2020. This is a return on investment of 9,688.58%, with an absolute return of $96.89 on top of the original $1.

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 68.16% of returns ($66.72) during this period. This means the inflation-adjusted * real* return of our $1 investment is $30.16. You may also want to account for capital gains tax, which would take your real return down to around $26 for most people.

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

Nominal |
$1 | $97.89 | 9,688.58% |

RealInflation Adjusted |
$1 | $31.16 | 3,016.47% |

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 1980 to latest available data for 2020 using average monthly close price.

Politics and news often influence economic performance. Here's what was happening at the time:

- Princess Victoria is crowned Princess of Sweden.
- Iranian protesters storm the Russian embassy in Iran.
- Abdou Diouf is elected president of Senegal after being Prime Minister for ten years.
- Cable News Network (CNN) is transmitted for the first time.
- Saddam Hussein, President of Iraq, declares a holy war on Iran.

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.
