Inflation by Spending Category

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 1660 and 1665.

Compare these values to the overall average of -5.34% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1660 → 1665
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1660. This table and charts use the earliest available data for each category.



How to Calculate Inflation Rate for $1, 1660 to 1665

This inflation calculator uses the following inflation rate formula:

CPI in 1665CPI in 1660
×
1660 USD value
=
1665 USD value

Then plug in historical CPI values. The U.S. CPI was 5 in the year 1660 and 3.8 in 1665:

3.85
×
$1
=
$0.76

$1 in 1660 has the same "purchasing power" or "buying power" as $0.76 in 1665.

To get the total inflation rate for the 5 years between 1660 and 1665, we use the following formula:

CPI in 1665 - CPI in 1660CPI in 1660
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

3.8 - 55
×
100
=
-24%

Data Source & Citation

Raw data for these calculations comes from the Bureau of Labor Statistics' (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.
