137.482.9
×
\$100
=
\$165.74

\$100 in 1991 has the same "purchasing power" or "buying power" as \$165.74 in 2021.

To get the total inflation rate for the 30 years between 1991 and 2021, we use the following formula:

CPI in 2021 - CPI in 1991CPI in 1991
×
100
=
Cumulative inflation rate (30 years)

Plugging in the values to this equation, we get:

137.4 - 82.982.9
×
100
=
66%
