How to Calculate Inflation Rate for $1, 1938 to 1940

This inflation calculator uses the following inflation rate formula:

CPI in 1938CPI in 1940
×
1940 USD value
=
1938 USD value

Then plug in historical CPI values. The U.S. CPI was 14 in the year 1940 and 14.1 in 1938:

14.114
×
$1
=
$1.01

$1 in 1940 has the same "purchasing power" or "buying power" as $1.01 in 1938.

To get the total inflation rate for the 2 years between 1938 and 1940, we use the following formula:

CPI in 1938 - CPI in 1940CPI in 1940
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

14.1 - 1414
×
100
=
1%
