How to Calculate Inflation Rate for $0.21 since 1900

This inflation calculator uses the following inflation rate formula:

CPI in 2018CPI in 1900
×
1900 USD value
=
2018 USD value

Then plug in historical CPI values. The U.S. CPI was 8.4 in the year 1900 and 252.038 in 2018:

252.0388.4
×
$0.21
=
$6.30

$0.21 in 1900 has the same "purchasing power" or "buying power" as $6.30 in 2018.

To get the total inflation rate for the 118 years between 1900 and 2018, we use the following formula:

CPI in 2018 - CPI in 1900CPI in 1900
×
100
=
Cumulative inflation rate (118 years)

Plugging in the values to this equation, we get:

252.038 - 8.48.4
×
100
=
2,900%

Comparison to S&P 500 Index

The average inflation rate of 2.92% has a compounding effect between 1900 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,900.45% over 118 years.

To help put this inflation into perspective, if we had invested $0.21 in the S&P 500 index in 1900, our investment would be nominally worth approximately $12,054.24 in 2018. This is a return on investment of 5,740,014.70%, with an absolute return of $12,054.03.

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 96.67% of returns ($11,652.29) during this period. This means the inflation-adjusted real return of our $0.21 investment is $401.74.
