How to Calculate Inflation Rate for $1, 1921 to 1925

Our calculations use the following inflation rate formula to calculate the change in value between 1921 and 1925:

CPI in 1921 CPI in 1925
×
1925 USD value
=
1921 USD value

Then plug in historical CPI values. The U.S. CPI was 17.5 in the year 1925 and 17.9 in 1921:

17.917.5
×
$1
=
$1.02

$1 in 1925 has the same "purchasing power" or "buying power" as $1.02 in 1921.

To get the total inflation rate for the 4 years between 1921 and 1925, we use the following formula:

CPI in 1921 - CPI in 1925CPI in 1925
×
100
=
Cumulative inflation rate (4 years)

Plugging in the values to this equation, we get:

17.9 - 17.517.5
×
100
=
2%
