Buying power of \$20 in 1973

This chart shows a calculation of buying power equivalence for \$20 in 1973 (price index tracking began in 1635).

For example, if you started with \$20, you would need to end with \$116.58 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$20 is equivalent to \$116.58 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 1973 dollars, the chart below shows how \$20 is worth less over 47 years.

Inflation by City

Inflation can vary widely by city, even within the United States. Here's how some cities fared in 1973 to 2020 (figures shown are purchasing power equivalents of \$20):

San Francisco, California experienced the highest rate of inflation during the 47 years between 1973 and 2020 (4.24%).

Detroit, Michigan experienced the lowest rate of inflation during the 47 years between 1973 and 2020 (3.59%).

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 £20.00 in 1973 would be equivalent to £246.39 in 2020, an absolute change of £226.39 and a cumulative change of 1,131.97%.

In Canada, CA\$20.00 in 1973 would be equivalent to CA\$111.35 in 2020, an absolute change of CA\$91.35 and a cumulative change of 456.73%.

Compare these numbers to the US's overall absolute change of \$96.58 and total percent change of 482.91%.

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 1973 and 2020.

Compare these values to the overall average of 3.82% per year:

Category Avg Inflation (%) Total Inflation (%) \$20 in 1973 → 2020

How to Calculate Inflation Rate for \$20, 1973 to 2020

Our calculations use the following inflation rate formula to calculate the change in value between 1973 and 2020:

CPI in 2020 CPI in 1973
×
1973 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 44.4 in the year 1973 and 258.81166666667 in 2020:

258.8116666666744.4
×
\$20
=
\$116.58

\$20 in 1973 has the same "purchasing power" or "buying power" as \$116.58 in 2020.

To get the total inflation rate for the 47 years between 1973 and 2020, we use the following formula:

CPI in 2020 - CPI in 1973CPI in 1973
×
100
=
Cumulative inflation rate (47 years)

Plugging in the values to this equation, we get:

258.81166666667 - 44.444.4
×
100
=
483%

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 1973 and 2020 (vs all-CPI inflation of 3.82%), for an inflation total of 487.24%.

When using the core inflation measurement, \$20 in 1973 is equivalent in buying power to \$117.45 in 2020, a difference of \$97.45. Recall that for All Items, the converted amount is \$116.58 with a difference of \$96.58.

In 1973, core inflation was 3.49%.

Comparison to S&P 500 Index

The average inflation rate of 3.82% has a compounding effect between 1973 and 2020. As noted above, this yearly inflation rate compounds to produce an overall price difference of 482.91% over 47 years.

To help put this inflation into perspective, if we had invested \$20 in the S&P 500 index in 1973, our investment would be nominally worth approximately \$2,479.13 in 2020. This is a return on investment of 12,295.67%, with an absolute return of \$2,459.13 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 82.84% of returns (\$2,053.83) during this period. This means the inflation-adjusted real return of our \$20 investment is \$405.30. You may also want to account for capital gains tax, which would take your real return down to around \$345 for most people.

Investment in S&P 500 Index, 1973-2020
Original Amount Final Amount Change
Nominal \$20 \$2,479.13 12,295.67%
Real
\$20 \$425.30 2,026.52%

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 1973 to latest available data for 2020 using average monthly close price.
