How to Calculate Inflation Rate for $100,000 since 1915

This inflation calculator uses the following inflation rate formula:

CPI in 2018CPI in 1915
×
1915 USD value
=
2018 USD value

Then plug in historical CPI values. The U.S. CPI was 10.1 in the year 1915 and 252.038 in 2018:

252.03810.1
×
$100,000
=
$2,495,425.74

$100,000 in 1915 has the same "purchasing power" or "buying power" as $2,495,425.74 in 2018.

To get the total inflation rate for the 103 years between 1915 and 2018, we use the following formula:

CPI in 2018 - CPI in 1915CPI in 1915
×
100
=
Cumulative inflation rate (103 years)

Plugging in the values to this equation, we get:

252.038 - 10.110.1
×
100
=
2,395%

Comparison to S&P 500 Index

The average inflation rate of 3.17% has a compounding effect between 1915 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 2,395.43% over 103 years.

To help put this inflation into perspective, if we had invested $100,000 in the S&P 500 index in 1915, our investment would be nominally worth approximately $2,317,290,070.93 in 2018. This is a return on investment of 2,317,190.07%, with an absolute return of $2,317,190,070.93.

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 95.99% of returns ($2,224,332,566.44) during this period. This means the inflation-adjusted real return of our $100,000 investment is $92,857,504.49.

Investment in S&P 500 Index, 1915-2018
Original Amount Final Amount Change
Nominal $100,000 $2,317,290,070.93 2,317,190.07%
