How to Calculate Inflation Rate for $100 since 1997

This inflation calculator uses the following inflation rate formula:

CPI in 2019CPI in 1997
×
1997 USD value
=
2019 USD value

Then plug in historical CPI values. The U.S. CPI was 160.5 in the year 1997 and 256.571 in 2019:

256.571160.5
×
$100
=
$159.86

$100 in 1997 has the same "purchasing power" or "buying power" as $159.86 in 2019.

To get the total inflation rate for the 22 years between 1997 and 2019, we use the following formula:

CPI in 2019 - CPI in 1997CPI in 1997
×
100
=
Cumulative inflation rate (22 years)

Plugging in the values to this equation, we get:

256.571 - 160.5160.5
×
100
=
60%

Alternate Measurements of Inflation

The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 2.00% per year between 1997 and 2019 (vs all-CPI inflation of 2.16%), for an inflation total of 54.63%.

When using the core inflation measurement, $100 in 1997 is equivalent in buying power to $154.63 in 2019, a difference of $54.63. Recall that for All Items, the converted amount is $159.86 with a difference of $59.86.

In 1997, core inflation was 2.38%.


Comparison to S&P 500 Index

The average inflation rate of 2.16% has a compounding effect between 1997 and 2019. As noted above, this yearly inflation rate compounds to produce an overall price difference of 59.86% over 22 years.

To help put this inflation into perspective, if we had invested $100 in the S&P 500 index in 1997, our investment would be nominally worth approximately $567.70 in 2019. This is a return on investment of 467.70%, with an absolute return of $467.70.

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 37.44% of returns ($175.13) during this period. This means the inflation-adjusted real return of our $100 investment is $292.57.

Investment in S&P 500 Index, 1997-2019
Original Amount Final Amount Change
Nominal $100 $567.70 467.70%
Real
Inflation Adjusted
$100 $292.57 292.57%
