### Buying power of \$100 in 1955

This chart shows a calculation of buying power equivalence for \$100 in 1955 (price index tracking began in 1635).

For example, if you started with \$100, you would need to end with \$962.58 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$962.58 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 1955 dollars, the chart below shows how \$100 buys less over the past 65 years.

### How to Calculate Inflation Rate for \$100 since 1955

This inflation calculator uses the following inflation rate formula:

CPI in 2020CPI in 1955
×
1955 USD value
=
2020 USD value

Then plug in historical CPI values. The U.S. CPI was 26.8 in the year 1955 and 257.971 in 2020:

257.97126.8
×
\$100
=
\$962.58

\$100 in 1955 has the same "purchasing power" or "buying power" as \$962.58 in 2020.

To get the total inflation rate for the 65 years between 1955 and 2020, we use the following formula:

CPI in 2020 - CPI in 1955CPI in 1955
×
100
=
Cumulative inflation rate (65 years)

Plugging in the values to this equation, we get:

257.971 - 26.826.8
×
100
=
863%

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

• The occupying powers grant full Sovereignty to West Germany.
• The Mainau Declaration against nuclear weapons is signed by 18 Nobel laureates.
• Rosa Parks is arrested in Montgomery, Alabama for refusing to give her seat to a white person and move to the back of the bus.
