How to Calculate Inflation Rate for $150 since 1920

This inflation calculator uses the following inflation rate formula:

CPI in 2018CPI in 1920
×
1920 USD value
=
2018 USD value

Then plug in historical CPI values. The U.S. CPI was 20 in the year 1920 and 252.146 in 2018:

252.14620
×
$150
=
$1,891.09

$150 in 1920 has the same "purchasing power" or "buying power" as $1,891.09 in 2018.

To get the total inflation rate for the 98 years between 1920 and 2018, we use the following formula:

CPI in 2018 - CPI in 1920CPI in 1920
×
100
=
Cumulative inflation rate (98 years)

Plugging in the values to this equation, we get:

252.146 - 2020

=
1,161%

Comparison to S&P 500 Index

The average inflation rate of 2.70% during these years has a compounding effect. As noted above, this yearly inflation rate produces an overall price difference of 1,160.73% over 98 years.

To help put this inflation into perspective, if you had invested $150 in the S&P 500 index in 1920, your investment would be worth approximately $2,331,385.34 in 2018. This is a change of 1,554,156.90%.

This means the nominal return on a $150 investment is $2,331,235.34, but inflation would eat into your real returns.

Inflation would account for 92.07% of your returns ($2,146,323.80), for an inflation-adjusted real return of about $184,911.55.
