Why a dollar today is worth only 11% of a dollar in 1964

Updated: November 10, 2021

\$100 in 1964 is equivalent in purchasing power to about \$892.22 today, an increase of \$792.22 over 57 years. The dollar had an average inflation rate of 3.91% per year between 1964 and today, producing a cumulative price increase of 792.22%.

This means that today's prices are 8.92 times higher than average prices since 1964, according to the Bureau of Labor Statistics consumer price index. A dollar today only buys 11.21% of what it could buy back then.

The inflation rate in 1964 was 1.31%. The current year-over-year inflation rate (2020 to 2021) is now 6.22%. If this number holds, \$100 today will be equivalent in buying power to \$106.22 next year. The current inflation rate page gives more detail on the latest inflation rates.

Buying power of \$100 in 1964

This chart shows a calculation of buying power equivalence for \$100 in 1964 (price index tracking began in 1635).

For example, if you started with \$100, you would need to end with \$892.22 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$892.22 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 1964 dollars, the chart below shows how \$100 is worth less over 57 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 by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1964 to 2021 (figures shown are purchasing power equivalents of \$100):

San Francisco, California experienced the highest rate of inflation during the 57 years between 1964 and 2021 (4.16%).

Detroit, Michigan experienced the lowest rate of inflation during the 57 years between 1964 and 2021 (3.73%).

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

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1964 would be equivalent to £2,128.31 in 2021, an absolute change of £2,028.31 and a cumulative change of 2,028.31%.

In Canada, CA\$100.00 in 1964 would be equivalent to CA\$827.71 in 2021, an absolute change of CA\$727.71 and a cumulative change of 727.71%.

Compare these numbers to the US's overall absolute change of \$792.22 and total percent change of 792.22%.

Inflation by Spending Category

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 1964 and 2021.

Compare these values to the overall average of 3.91% per year:

Category Avg Inflation (%) Total Inflation (%) \$100 in 1964 → 2021
Food and beverages 3.89 782.15 882.15
Housing 4.17 926.23 1,026.23

How to Calculate Inflation Rate for \$100 since 1964

Our calculations use the following inflation rate formula to calculate the change in value between 1964 and today:

CPI today CPI in 1964
×
1964 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 31 in the year 1964 and 276.589 in 2021:

276.58931
×
\$100
=
\$892.22

\$100 in 1964 has the same "purchasing power" or "buying power" as \$892.22 in 2021.

To get the total inflation rate for the 57 years between 1964 and 2021, we use the following formula:

CPI in 2021 - CPI in 1964CPI in 1964
×
100
=
Cumulative inflation rate (57 years)

Plugging in the values to this equation, we get:

276.589 - 3131

=
792%

Alternate Measurements of Inflation

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 3.84% per year between 1964 and 2021 (vs all-CPI inflation of 3.91%), for an inflation total of 755.22%.

When using the core inflation measurement, \$100 in 1964 is equivalent in buying power to \$855.22 in 2021, a difference of \$755.22. Recall that for All Items, the converted amount is \$892.22 with a difference of \$792.22.

In 1964, core inflation was 1.50%.

Comparison to S&P 500 Index

The average inflation rate of 3.91% has a compounding effect between 1964 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 792.22% over 57 years.

To help put this inflation into perspective, if we had invested \$100 in the S&P 500 index in 1964, our investment would be nominally worth approximately \$30,395.49 in 2021. This is a return on investment of 30,295.49%, with an absolute return of \$30,295.49 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 88.79% of returns (\$26,988.77) during this period. This means the inflation-adjusted real return of our \$100 investment is \$3,306.72. You may also want to account for capital gains tax, which would take your real return down to around \$2,811 for most people.

Investment in S&P 500 Index, 1964-2021
Original Amount Final Amount Change
Nominal \$100 \$30,395.49 30,295.49%
Real
\$100 \$3,406.72 3,306.72%

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 1964 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:

• Jomo Kenyatta becomes first President of Kenya after it becomes a republic.
• Nelson Mandela is sentenced to life-long imprisonment in South Africa.
• President Lyndon B. Johnson signs the Civil Rights Act and Voting Rights Act into law.
