## Buying power of \$55 in 1906

This chart shows a calculation of buying power equivalence for \$55 in 1906 (price index tracking began in 1635).

For example, if you started with \$55, you would need to end with \$1,645.08 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$55 is equivalent to \$1,645.08 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 1906 dollars, the chart below shows how \$55 is worth less over 115 years.

## 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 1906 and 2021.

Compare these values to the overall average of 3.00% per year:

Category Avg Inflation (%) Total Inflation (%) \$55 in 1906 → 2021
Food and beverages 3.87 7,759.54 4,322.75
Housing 4.15 10,604.72 5,887.59
Apparel 1.95 822.19 507.21

## How to Calculate Inflation Rate for \$55 since 1906

Our calculations use the following inflation rate formula to calculate the change in value between 1906 and today:

CPI today CPI in 1906
×
1906 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 9 in the year 1906 and 269.195 in 2021:

269.1959
×
\$55
=
\$1,645.08

\$55 in 1906 has the same "purchasing power" or "buying power" as \$1,645.08 in 2021.

To get the total inflation rate for the 115 years between 1906 and 2021, we use the following formula:

CPI in 2021 - CPI in 1906CPI in 1906
×
100
=
Cumulative inflation rate (115 years)

Plugging in the values to this equation, we get:

269.195 - 99
×
100
=
2,891%

## Comparison to S&P 500 Index

The average inflation rate of 3.00% has a compounding effect between 1906 and 2021. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,891.06% over 115 years.

To help put this inflation into perspective, if we had invested \$55 in the S&P 500 index in 1906, our investment would be nominally worth approximately \$2,285,856.49 in 2021. This is a return on investment of 4,156,002.71%, with an absolute return of \$2,285,801.49 on top of the original \$55.

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 96.66% of returns (\$2,209,433.42) during this period. This means the inflation-adjusted real return of our \$55 investment is \$76,368.07. You may also want to account for capital gains tax, which would take your real return down to around \$64,913 for most people.

Investment in S&P 500 Index, 1906-2021
Original Amount Final Amount Change
Nominal \$55 \$2,285,856.49 4,156,002.71%
Real
\$55 \$76,423.07 138,851.04%

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 1906 to latest available data for 2021 using average monthly close price.
