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 1720 and 1722.

Compare these values to the overall average of -1.20% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1720 → 1722
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00

How to Calculate Inflation Rate for $1, 1720 to 1722

This inflation calculator uses the following inflation rate formula:

CPI in 1722CPI in 1720
×
1720 USD value
=
1722 USD value

Then plug in historical CPI values. The U.S. CPI was 4.2 in the year 1720 and 4.1 in 1722:

4.14.2
×
$1
=
$0.98

$1 in 1720 has the same "purchasing power" or "buying power" as $0.98 in 1722.

To get the total inflation rate for the 2 years between 1720 and 1722, we use the following formula:

CPI in 1722 - CPI in 1720CPI in 1720
×
100
=
Cumulative inflation rate (2 years)

Plugging in the values to this equation, we get:

4.1 - 4.24.2
×
100
=
-2%

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.
