How to Calculate Inflation Rate for $500, 1985 to 2018

This inflation calculator uses the following inflation rate formula:

CPI in 2018CPI in 1985
×
1985 USD value
=
2018 USD value

Then plug in historical CPI values. The U.S. CPI was 107.6 in the year 1985 and 251.10683333333 in 2018:

251.10683333333107.6
×
$500
=
$1,166.85

$500 in 1985 has the same "purchasing power" or "buying power" as $1,166.85 in 2018.

To get the total inflation rate for the 33 years between 1985 and 2018, we use the following formula:

CPI in 2018 - CPI in 1985CPI in 1985
×
100
=
Cumulative inflation rate (33 years)

Plugging in the values to this equation, we get:

251.10683333333 - 107.6107.6
×
100
=
133%

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 2.64% per year between 1985 and 2018 (vs all-CPI inflation of 2.60%), for an inflation total of 136.05%.

When using the core inflation measurement, $500 in 1985 is equivalent in buying power to $1,180.24 in 2018, a difference of $680.24. Recall that for All Items, the converted amount is $1,166.85 with a difference of $666.85.

In 1985, core inflation was 4.37%.


Comparison to S&P 500 Index

The average inflation rate of 2.60% has a compounding effect between 1985 and 2018. As noted above, this yearly inflation rate compounds to produce an overall price difference of 133.37% over 33 years.

To help put this inflation into perspective, if we had invested $500 in the S&P 500 index in 1985, our investment would be nominally worth approximately $16,398.85 in 2018. This is a return on investment of 3,179.77%, with an absolute return of $15,898.85.

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 57.15% of returns ($9,086.15) during this period. This means the inflation-adjusted real return of our $500 investment is $6,812.70.

Investment in S&P 500 Index, 1985-2018

Nominal $500 $16,398.85 3,179.77%
