Purchasing power increased by 2.11% in 1787 compared to the previous year, 1786. On average, you would have to spend 2.11% less money in 1787 than in 1786 for the same item. This is an example of deflation.
In other words, $100 in 1786 is equivalent in purchasing power to $97.89 in 1787.
The 1786 inflation rate was -2.06%. The inflation rate in 1787 was -2.11%. The 1787 inflation rate is lower compared to the average inflation rate of 1.44% per year between 1787 and 2018.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1787 was 9.3. It was 9.5 in the previous year, 1786. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1787 CPI is less than 1786 CPI, negative inflation (also known as deflation) has occurred.
|Average inflation rate||-2.11%|
|Converted amount ($100 base)||$97.89|
|Price difference ($100 base)||$-2.11|
|CPI in 1786||9.5|
|CPI in 1787||9.3|
|Inflation in 1786||-2.06%|
|Inflation in 1787||-2.11%|
Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1786 would be equivalent to £100.00 in 1787, an absolute change of £0.00 and a cumulative change of 0.00%.
Compare these numbers to the US's overall absolute change of $-2.11 and total percent change of -2.11%.
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 1786 and 1787.
Compare these values to the overall average of -2.11% per year:
|Category||Avg Inflation (%)||Total Inflation (%)||$100 in 1786 → 1787|
|Used cars and trucks||0.00||0.00||100.00|
|Medical care services||0.00||0.00||100.00|
|Medical care commodities||0.00||0.00||100.00|
It's important to note that not all categories may be tracked since 1786. 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 9.5 in the year 1786 and 9.3 in 1787:
$100 in 1786 has the same "purchasing power" or "buying power" as $97.89 in 1787.
To get the total inflation rate for the 1 years between 1786 and 1787, we use the following formula:
Plugging in the values to this equation, we get:
Politics and news often influence economic performance. Here's what was happening at the time:
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.
