This chart shows a calculation of buying power equivalence for $20 in 1965 (price index tracking began in 1635).

For example, if you started with $20, you would need to end with $173.69 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $20 is equivalent to $173.69 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 1965 dollars, the chart below shows how $20 is worth less over 56 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 1965 to 2021 (figures shown are purchasing power equivalents of $20):

**San Francisco, California**: 4.20% average rate, $20 → $199.90, cumulative change of 899.48%**Seattle, Washington**: 4.09% average rate, $20 → $188.48, cumulative change of 842.42%**Boston, Massachusetts**: 3.99% average rate, $20 → $178.76, cumulative change of 793.79%**New York**: 3.98% average rate, $20 → $177.97, cumulative change of 789.85%**Dallas-Fort Worth, Texas**: 3.85% average rate, $20 → $166.05, cumulative change of 730.24%**Atlanta, Georgia**: 3.84% average rate, $20 → $165.26, cumulative change of 726.31%**Philadelphia, Pennsylvania**: 3.81% average rate, $20 → $162.41, cumulative change of 712.04%**Houston, Texas**: 3.78% average rate, $20 → $159.94, cumulative change of 699.68%**Chicago, Illinois**: 3.77% average rate, $20 → $158.98, cumulative change of 694.89%**Detroit, Michigan**: 3.75% average rate, $20 → $157.09, cumulative change of 685.47%

San Francisco, California experienced the highest rate of inflation during the 56 years between 1965 and 2021 (4.20%).

Detroit, Michigan experienced the lowest rate of inflation during the 56 years between 1965 and 2021 (3.75%).

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 £20.00 in 1965 would be equivalent to £397.24 in 2021, an absolute change of £377.24 and a cumulative change of 1,886.22%.

In Canada, CA$20.00 in 1965 would be equivalent to CA$160.70 in 2021, an absolute change of CA$140.70 and a cumulative change of 703.51%.

Compare these numbers to the US's overall absolute change of $153.69 and total percent change of 768.47%.

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 1965 and 2021.

Compare these values to the overall average of 3.94% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $20 in 1965 → 2021 |
---|---|---|---|

Food and beverages | 3.88 | 743.17 | 168.63 |

Housing | 4.16 | 879.66 | 195.93 |

Apparel | 1.66 | 151.56 | 50.31 |

Transportation | 3.55 | 604.72 | 140.94 |

Medical care | 5.57 | 1,980.65 | 416.13 |

Recreation | 1.13 | 87.22 | 37.44 |

Education and communication | 1.83 | 175.74 | 55.15 |

Other goods and services | 4.94 | 1,386.54 | 297.31 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1965. 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 1965 and today:

Then plug in historical CPI values. The U.S. CPI was 31.5 in the year 1965 and 273.567 in 2021:

$20 in 1965 has the same "purchasing power" or "buying power" as $173.69 in 2021.

To get the total inflation rate for the 56 years between 1965 and 2021, we use the following formula:

CPI in 2021 - CPI in 1965CPI in 1965

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 3.87% per year between 1965 and 2021 (vs all-CPI inflation of 3.94%), for an inflation total of 739.57%.

When using the core inflation measurement, $20 in 1965 is equivalent in buying power to $167.91 in 2021, a difference of $147.91. Recall that for All Items, the converted amount is $173.69 with a difference of $153.69.

In 1965, core inflation was 1.43%.

The average inflation rate of 3.94% has a compounding effect between 1965 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 768.47% over 56 years.

To help put this inflation into perspective, if we had invested $20 in the S&P 500 index in 1965, our investment would be * nominally* worth approximately $5,241.70 in 2021. This is a return on investment of 26,108.48%, with an absolute return of $5,221.70 on top of the original $20.

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 88.49% of returns ($4,638.14) during this period. This means the inflation-adjusted * real* return of our $20 investment is $583.56. You may also want to account for capital gains tax, which would take your real return down to around $496 for most people.

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

Nominal |
$20 | $5,241.70 | 26,108.48% |

RealInflation Adjusted |
$20 | $603.56 | 2,917.79% |

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 1965 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:

- Aleksei Leonov, a Soviet cosmonaut, makes the first Spacewalk, when he leaves the Hos spacecraft for 12 minutes.
- Winston Churchill, is given the largest state funeral ever, it takes place in St Paul's Cathedral, London.
- The Supreme Court legalises the use of contraception by married couples.
- France becomes the third nation in space, after launching its first satellite.
- Lyndon B. Johnson, US President, signs the Voting Rights Act, making voting discrimination against minorities illegal.

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.
