Inflation in 1661 and Its Effect on Dollar Value

Purchasing power increased by 16.00% in 1661 compared to the previous year, 1660. On average, you would have to spend 16.00% less money in 1661 than in 1660 for the same item. This is an example of deflation.

In other words, $1 in 1660 is equivalent in purchasing power to $0.84 in 1661.

The 1660 inflation rate was 13.64%. The inflation rate in 1661 was -16.00%. The 1661 inflation rate is lower compared to the average inflation rate of 1.15% per year between 1661 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1661 was 4.2. It was 5 in the previous year, 1660. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1661 CPI is less than 1660 CPI, negative inflation (also known as deflation) has occurred.

How to Calculate Inflation Rate for $1, 1660 to 1661

This inflation calculator uses the following inflation rate formula:

CPI in 1661CPI in 1660
×
1660 USD value
=
1661 USD value

Then plug in historical CPI values. The U.S. CPI was 5 in the year 1660 and 4.2 in 1661:

4.25
×
$1
=
$0.84

$1 in 1660 has the same "purchasing power" or "buying power" as $0.84 in 1661.

To get the total inflation rate for the 1 years between 1660 and 1661, we use the following formula:

CPI in 1661 - CPI in 1660CPI in 1660
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

4.2 - 55
×
100
=
-16%
