This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 3.7 in the year 1684 and 4.1 in 1685:
$100 in 1684 has the same "purchasing power" or "buying power" as $110.81 in 1685.
To get the total inflation rate for the 1 years between 1684 and 1685, 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.
