Core inflation averaged 1.80% per year between 2008 and 2018 (vs all-CPI inflation of 1.55%), for an inflation total of 19.48%.

When using the core inflation measurement, $2,981 in 2008 is equivalent in buying power to $3,561.70 in 2018, a difference of $580.70. Recall that for All Items, the converted amount is $3,476.73 with a difference of $495.73.

In 2008, core inflation was 2.30%.

Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. Chained inflation averaged 1.32% per year between 2008 and 2018, a total inflation amount of 19.48%.

According to the Chained CPI measurement, $2,981 in 2008 is equal in buying power to $3,400.23 in 2018, a difference of $419.23 (versus a converted amount of $3,476.73/change of $495.73 for All Items).

Comparison to S&P 500 Index

The average inflation rate of 1.55% has a compounding effect between 2008 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 16.63% over 10 years.

To help put this inflation into perspective, if we had invested $2,981 in the S&P 500 index in 2008, our investment would be nominally worth approximately $7,078.81 in 2018. This is a return on investment of 137.46%, with an absolute return of $4,097.81.

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 14.26% of returns ($584.28) during this period. This means the inflation-adjusted real return of our $2,981 investment is $3,513.53.
