### Buying power of \$20 in 1974

This chart shows a calculation of buying power equivalence for \$20 in 1974 (price index tracking began in 1635).

For example, if you started with \$20, you would need to end with \$103.72 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$20 is equivalent to \$103.72 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 1974 dollars, the chart below shows how \$20 buys less over the past 45 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 1974 to 2019 (figures shown are purchasing power equivalents of \$20):

San Francisco, California experienced the highest rate of inflation during the 45 years between 1974 and 2019 (4.19%).

Detroit, Michigan experienced the lowest rate of inflation during the 45 years between 1974 and 2019 (3.49%).

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 1974 would be equivalent to £206.71 in 2019, an absolute change of £186.71 and a cumulative change of 933.57%.

In Canada, CA\$20.00 in 1974 would be equivalent to CA\$96.67 in 2019, an absolute change of CA\$76.67 and a cumulative change of 383.33%.

Compare these numbers to the US's overall absolute change of \$83.72 and total percent change of 418.58%.

### Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1974 and 2019.

Compare these values to the overall average of 3.73% per year:

Category Avg Inflation (%) Total Inflation (%) \$20 in 1974 → 2019
Food and beverages 3.47 364.82 92.96
Housing 3.99 480.68 116.14
Apparel 1.30 78.67 35.73
Transportation 3.44 358.66 91.73
Medical care 5.63 1,076.47 235.29
Recreation 1.10 63.34 32.67
Education and communication 1.85 128.09 45.62
Other goods and services 5.02 806.49 181.30

### How to Calculate Inflation Rate for \$20, 1974 to 2019

This inflation calculator uses the following inflation rate formula:

CPI in 2019CPI in 1974
×
1974 USD value
=
2019 USD value

Then plug in historical CPI values. The U.S. CPI was 49.3 in the year 1974 and 255.6575 in 2019:

255.657549.3
×
\$20
=
\$103.72

\$20 in 1974 has the same "purchasing power" or "buying power" as \$103.72 in 2019.

To get the total inflation rate for the 45 years between 1974 and 2019, we use the following formula:

CPI in 2019 - CPI in 1974CPI in 1974
×
100
=
Cumulative inflation rate (45 years)

Plugging in the values to this equation, we get:

255.6575 - 49.349.3
×
100
=
419%

### 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 3.79% per year between 1974 and 2019 (vs all-CPI inflation of 3.73%), for an inflation total of 433.40%.

When using the core inflation measurement, \$20 in 1974 is equivalent in buying power to \$106.68 in 2019, a difference of \$86.68. Recall that for All Items, the converted amount is \$103.72 with a difference of \$83.72.

In 1974, core inflation was 8.25%.

### Comparison to S&P 500 Index

The average inflation rate of 3.73% has a compounding effect between 1974 and 2019. As noted above, this yearly inflation rate compounds to produce an overall price difference of 418.58% over 45 years.

To help put this inflation into perspective, if we had invested \$20 in the S&P 500 index in 1974, our investment would be nominally worth approximately \$2,459.39 in 2019. This is a return on investment of 12,196.97%, with an absolute return of \$2,439.39 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 80.72% of returns (\$1,985.13) during this period. This means the inflation-adjusted real return of our \$20 investment is \$454.26. You may also want to account for capital gains tax, which would take your real return down to around \$386 for most people.

Investment in S&P 500 Index, 1974-2019
Original Amount Final Amount Change
Nominal \$20 \$2,459.39 12,196.97%
Real
\$20 \$474.26 2,271.30%

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 1974 to latest available data for 2019 using average monthly close price.

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

• Ayatollah Khomeini, appeals for an Islamic republic of Iran.
• The 1,000th victim of the Northern Ireland conflict between republican and loyalist paramilitaries is taken.
• President Richard Nixon announces his resignation.

### Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (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.
