Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

This chart shows the average rate of inflation for select CPI categories between 1655 and 2025.

Compare these values to the overall average of 1.02% per year:

How to calculate inflation rate for $400,000,000,000,000, 1655 to 2025

Our calculations use the following inflation rate formula to calculate the change in value between 1655 and 2025:

CPI in 2025CPI in 1655
×
1655 USD value
=
2025 USD value

Then plug in historical CPI values. The U.S. CPI was 7.5 in the year 1655 and 321.05125 in 2025:

321.051257.5
×
$400,000,000,000,000
=
$17,122,733,333,333,332

$400,000,000,000,000 in 1655 has the same "purchasing power" or "buying power" as $17,122,733,333,333,332 in 2025.

To get the total inflation rate for the 370 years between 1655 and 2025, we use the following formula:

CPI in 2025 - CPI in 1655CPI in 1655
×
100
=
Cumulative inflation rate (370 years)

Plugging in the values to this equation, we get:

321.05125 - 7.57.5
×
100
=
4,181%
