How to Calculate Inflation Rate for $0.30, 1973 to 2017

This inflation calculator uses the following inflation rate formula:

CPI in 2017CPI in 1973
×
1973 USD value
=
2017 USD value

Then plug in historical CPI values. The U.S. CPI was 44.4 in the year 1973 and 245.12 in 2017:

245.1244.4
×
$0.30
=
$1.66

$0.30 in 1973 has the same "purchasing power" or "buying power" as $1.66 in 2017.

To get the total inflation rate for the 44 years between 1973 and 2017, we use the following formula:

CPI in 2017 - CPI in 1973CPI in 1973
×
100
=
Cumulative inflation rate (44 years)

Plugging in the values to this equation, we get:

245.12 - 44.444.4
×
100
=
452%

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 3.96% per year between 1973 and 2017 (vs all-CPI inflation of 3.96%), for an inflation total of 453.31%.

When using the core inflation measurement, $0.30 in 1973 is equivalent in buying power to $1.66 in 2017, a difference of $1.36. Recall that for All Items, the converted amount is $1.66 with a difference of $1.36.

In 1973, core inflation was 3.48%.


Comparison to S&P 500 Index

The average inflation rate of 3.96% has a compounding effect between 1973 and 2017. As noted above, this yearly inflation rate compounds to produce an overall price difference of 452.07% over 44 years.

To help put this inflation into perspective, if we had invested $0.30 in the S&P 500 index in 1973, our investment would be nominally worth approximately $25.85 in 2017. This is a return on investment of 8,518.00%, with an absolute return of $25.55.

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 81.89% of returns ($20.93) during this period. This means the inflation-adjusted real return of our $0.30 investment is $4.63.

Investment in S&P 500 Index, 1973-2017
Original Amount Final Amount Change
Nominal $0.30 $25.85 8,518.00%
Real
Inflation Adjusted
$0.30 $4.63 1,542.91%
