The 1664 inflation rate was 0.00%. The inflation rate in 1665 was -15.56%. The 1665 inflation rate is lower compared to the average inflation rate of 1.20% per year between 1665 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1665 was 3.8. It was 4.5 in the previous year, 1664. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1665 CPI is less than 1664 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for $100, 1664 to 1665

This inflation calculator uses the following inflation rate formula:

CPI in 1665CPI in 1664
×
1664 USD value
=
1665 USD value

Then plug in historical CPI values. The U.S. CPI was 4.5 in the year 1664 and 3.8 in 1665:

3.84.5
×
$100
=
$84.44

$100 in 1664 has the same "purchasing power" or "buying power" as $84.44 in 1665.

To get the total inflation rate for the 1 years between 1664 and 1665, we use the following formula:

CPI in 1665 - CPI in 1664CPI in 1664
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

3.8 - 4.54.5
×
