Purchasing power decreased by 10.81% in 1685 compared to the previous year, 1684. On average, you would have to spend 10.81% more money in 1685 than in 1684 for the same item.
In other words, $1 in 1684 is equivalent in purchasing power to $1.11 in 1685.
The 1684 inflation rate was 0.00%. The inflation rate in 1685 was 10.81%. The 1685 inflation rate is higher compared to the average inflation rate of 1.24% per year between 1685 and 2018.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1685 was 4.1. It was 3.7 in the previous year, 1684. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.
|Average inflation rate||10.81%|
|Converted amount ($1 base)||$1.11|
|Price difference ($1 base)||$0.11|
|CPI in 1684||3.700|
|CPI in 1685||4.100|
|Inflation in 1684||0.00%|
|Inflation in 1685||10.81%|
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 1684 and 1685.
Compare these values to the overall average of 10.81% per year:
|Category||Avg Inflation (%)||Total Inflation (%)||$1 in 1684 → 1685|
|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 1684. 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 3.7 in the year 1684 and 4.1 in 1685:
$1 in 1684 has the same "purchasing power" or "buying power" as $1.11 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.
