### How to Calculate Inflation Rate for \$100, 1925 to 2017

This inflation calculator uses the following inflation rate formula:

CPI in 2017CPI in 1925
×
1925 USD value
=
2017 USD value

Then plug in historical CPI values. The U.S. CPI was 17.5 in the year 1925 and 245.12 in 2017:

245.1217.5
×
\$100
=
\$1,400.69

\$100 in 1925 has the same "purchasing power" or "buying power" as \$1,400.69 in 2017.

To get the total inflation rate for the 92 years between 1925 and 2017, we use the following formula:

CPI in 2017 - CPI in 1925CPI in 1925
×
100
=
Cumulative inflation rate (92 years)

Plugging in the values to this equation, we get:

245.12 - 17.517.5
×
100
=
1,301%

### Comparison to S&P 500 Index

The average inflation rate of 2.91% has a compounding effect between 1925 and 2017. As noted above, this yearly inflation rate compounds to produce an overall price difference of 1,300.69% over 92 years.

To help put this inflation into perspective, if we had invested \$100 in the S&P 500 index in 1925, our investment would be nominally worth approximately \$904,902.13 in 2017. This is a return on investment of 904,802.13%, with an absolute return of \$904,802.13.

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 92.86% of returns (\$840,205.05) during this period. This means the inflation-adjusted real return of our \$100 investment is \$64,597.08.

Investment in S&P 500 Index, 1925-2017
