In other words, $100 in 1643 is equivalent in purchasing power to $71.94 in 1644.

The 1643 inflation rate was 44.79%. The inflation rate in 1644 was -28.06%. The 1644 inflation rate is lower compared to the average inflation rate of 0.87% per year between 1644 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1644 was 10. It was 13.9 in the previous year, 1643. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1644 CPI is less than 1643 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for $100, 1643 to 1644

This inflation calculator uses the following inflation rate formula:

CPI in 1644CPI in 1643
×
1643 USD value

1644 USD value

Then plug in historical CPI values. The U.S. CPI was 13.9 in the year 1643 and 10 in 1644:

1013.9
×
$100
=
$71.94

$100 in 1643 has the same "purchasing power" or "buying power" as $71.94 in 1644.

To get the total inflation rate for the 1 years between 1643 and 1644, we use the following formula:

CPI in 1644 - CPI in 1643CPI in 1643
×
100
