How to Calculate Inflation Rate for $1, 1778 to 1780

This inflation calculator uses the following inflation rate formula:

CPI in 1778CPI in 1780
×
1780 USD value
=
1778 USD value

Then plug in historical CPI values. The U.S. CPI was 13.7 in the year 1780 and 13.8 in 1778:

13.813.7
×
$1
=
$1.01

$1 in 1780 has the same "purchasing power" or "buying power" as $1.01 in 1778.

To get the total inflation rate for the 2 years between 1778 and 1780, we use the following formula:

CPI in 1778 - CPI in 1780CPI in 1780
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

13.8 - 13.713.7
×
100
=
1%
