How to Calculate Inflation Rate for $20 since 2009

This inflation calculator uses the following inflation rate formula:

CPI in 2019CPI in 2009
×
2009 USD value
=
2019 USD value

Then plug in historical CPI values. The U.S. CPI was 214.537 in the year 2009 and 256.092 in 2019:

256.092214.537
×
$20
=
$23.87

$20 in 2009 has the same "purchasing power" or "buying power" as $23.87 in 2019.

To get the total inflation rate for the 10 years between 2009 and 2019, we use the following formula:

CPI in 2019 - CPI in 2009CPI in 2009
×
100
=
Cumulative inflation rate (10 years)

Plugging in the values to this equation, we get:

256.092 - 214.537214.537

=
19%

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 1.78% per year between 2009 and 2019 (vs all-CPI inflation of 1.79%), for an inflation total of 19.32%.

When using the core inflation measurement, $20 in 2009 is equivalent in buying power to $23.86 in 2019, a difference of $3.86. Recall that for All Items, the converted amount is $23.87 with a difference of $3.87.

In 2009, core inflation was 1.70%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.48% per year between 2009 and 2019, a total inflation amount of 19.32%.

According to the Chained CPI measurement, $20 in 2009 is equal in buying power to $23.16 in 2019, a difference of $3.16 (versus a converted amount of $23.87/change of $3.87 for All Items).

In 2009, chained inflation was -0.47%.


Comparison to S&P 500 Index

The average inflation rate of 1.79% has a compounding effect between 2009 and 2019. As noted above, this yearly inflation rate compounds to produce an overall price difference of 19.37% over 10 years.

To help put this inflation into perspective, if we had invested $20 in the S&P 500 index in 2009, our investment would be nominally worth approximately $83.54 in 2019. This is a return on investment of 317.68%, with an absolute return of $63.54.

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 16.23% of returns ($10.31) during this period. This means the inflation-adjusted real return of our $20 investment is $53.23.

Investment in S&P 500 Index, 2009-2019
Original Amount Final Amount Change
Nominal $20 $83.54 317.68%
