|Average inflation rate||0.00%|
|Converted amount ($1 base)||$1|
|Price difference ($1 base)||$0.00|
|CPI in 1665||3.800|
|CPI in 1666||3.800|
|Inflation in 1665||-15.56%|
|Inflation in 1666||0.00%|
CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1665 and 1666.
Compare these values to the overall average of 0.00% per year:
|Category||Avg Inflation (%)||Total Inflation (%)||$1 in 1665 → 1666|
|Used cars and trucks||0.00||0.00||1.00|
|Medical care services||0.00||0.00||1.00|
|Medical care commodities||0.00||0.00||1.00|
It's important to note that not all categories may be tracked since 1665. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 3.8 in the year 1665 and 3.8 in 1666:
$1 in 1665 has the same "purchasing power" or "buying power" as $1 in 1666.
To get the total inflation rate for the 1 years between 1665 and 1666, we use the following formula:
Plugging in the values to this equation, we get:
Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
