### Buying power of \$100 in 1917

This chart shows a calculation of buying power equivalence for \$100 in 1917 (price index tracking began in 1635).

For example, if you started with \$100, you would need to end with \$5.22 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When \$100 is equivalent to \$5.22 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 1917 dollars, the chart below shows how \$100 buys less over the past 100 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:

### How to Calculate Inflation Rate for \$100, 1917 to 2017

This inflation calculator uses the following inflation rate formula:

CPI in 1917CPI in 2017
×
2017 USD value
=
1917 USD value

Then plug in historical CPI values. The U.S. CPI was 245.12 in the year 2017 and 12.8 in 1917:

12.8245.12
×
\$100
=
\$5.22

\$100 in 2017 has the same "purchasing power" or "buying power" as \$5.22 in 1917.

To get the total inflation rate for the 100 years between 1917 and 2017, we use the following formula:

CPI in 1917 - CPI in 2017CPI in 2017
×
100
=
Cumulative inflation rate (100 years)

Plugging in the values to this equation, we get:

12.8 - 245.12245.12
×
100
=
-95%

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