How to Calculate Inflation Rate for $1, 1966 to 1970

This inflation calculator uses the following inflation rate formula:

CPI in 1966CPI in 1970
×
1970 USD value
=
1966 USD value

Then plug in historical CPI values. The U.S. CPI was 38.8 in the year 1970 and 32.4 in 1966:

32.438.8
×
$1
=
$0.84

$1 in 1970 has the same "purchasing power" or "buying power" as $0.84 in 1966.

To get the total inflation rate for the 4 years between 1966 and 1970, we use the following formula:

CPI in 1966 - CPI in 1970CPI in 1970
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

32.4 - 38.838.8
×
100
=
-16%

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 5.04% per year between 1970 and 1966 (vs all-CPI inflation of 4.61%), for an inflation total of 21.72%.

When using the core inflation measurement, $1 in 1970 is equivalent in buying power to $1.22 in 1966, a difference of $0.22. Recall that for All Items, the converted amount is $0.84 with a difference of $-0.16.

In 1970, core inflation was 2.44%.
