This chart shows a calculation of buying power equivalence for $100 in 1966 (price index tracking began in 1635).

For example, if you started with $100, you would need to end with $756.54 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $100 is equivalent to $756.54 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 1966 dollars, the chart below shows how $100 is worth less over 51 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 £100.00 in 1966 would be equivalent to £1,770.84 in 2017, an absolute change of £1,670.84 and a cumulative change of 1,670.84%.

In Canada, CA$100.00 in 1966 would be equivalent to CA$736.72 in 2017, an absolute change of CA$636.72 and a cumulative change of 636.72%.

Compare these numbers to the US's overall absolute change of $656.54 and total percent change of 656.54%.

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 1966 and 2017.

Compare these values to the overall average of 4.05% per year:

For all these visualizations, it's important to note that not all categories may have been tracked since 1966. 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 1966 and 2017:

2017 USD value

Then plug in historical CPI values. The U.S. CPI was 32.4 in the year 1966 and 245.12 in 2017:

$100 in 1966 has the same "purchasing power" or "buying power" as $756.54 in 2017.

To get the total inflation rate for the 51 years between 1966 and 2017, we use the following formula:

CPI in 2017 - CPI in 1966CPI in 1966

Plugging in the values to this equation, we get:

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 4.03% per year between 1966 and 2017 (vs all-CPI inflation of 4.05%), for an inflation total of 651.88%.

When using the core inflation measurement, $100 in 1966 is equivalent in buying power to $751.88 in 2017, a difference of $651.88. Recall that for All Items, the converted amount is $756.54 with a difference of $656.54.

In 1966, core inflation was 2.44%.

The average inflation rate of 4.05% has a compounding effect between 1966 and 2017. As noted above, this yearly inflation rate compounds to produce an overall price difference of 656.54% over 51 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 1966, our investment would be * nominally* worth approximately $13,688.90 in 2017. This is a return on investment of 13,588.90%, with an absolute return of $13,588.90 on top of the original $100.

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 86.78% of returns ($11,879.50) during this period. This means the inflation-adjusted * real* return of our $100 investment is $1,709.40. You may also want to account for capital gains tax, which would take your real return down to around $1,453 for most people.

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

Nominal |
$100 | $13,688.90 | 13,588.90% |

RealInflation Adjusted |
$100 | $1,809.40 | 1,709.40% |

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 1966 to latest available data for 2017 using average monthly close price.

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

- Soviet Luna 9 lands on the Moon.
- Demonstrations are held against the Vietnam War in the United States, Europe and Australia.
- A treaty prohibiting the use of nuclear weapons in outer space is signed by the United States and the USSR.

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.
