## How to Calculate Inflation Rate for \$1, 1787 to 1790

Our calculations use the following inflation rate formula to calculate the change in value between 1787 and 1790:

CPI in 1787 CPI in 1790
×
1790 USD value
=
1787 USD value

Then plug in historical CPI values. The U.S. CPI was 9.2 in the year 1790 and 9.3 in 1787:

9.39.2
×
\$1
=
\$1.01

\$1 in 1790 has the same "purchasing power" or "buying power" as \$1.01 in 1787.

To get the total inflation rate for the 3 years between 1787 and 1790, we use the following formula:

CPI in 1787 - CPI in 1790CPI in 1790
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

9.3 - 9.29.2
×
100
=
1%

Politics and news often influence economic performance. Here's what was happening at the time:

• George Washington, delivers his first State of the Union address as president.
• The Swedish navy capture a third of the Russian fleet in the Second Battle of Svensksund.
• Columbia Rediviva, returns to Boston, having become the first American ship to circumnavigate the world.
• Turkish fortress of Izmail, thought to be impenetrable, is captured by the Russians under the command of Suvorov.
