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 1640 and 2025.

Compare these values to the overall average of 0.92% per year:

How to calculate inflation rate for $400,000,000,000,000 since 1640

Our calculations use the following inflation rate formula to calculate the change in value between 1640 and today:

CPI today CPI in 1640
×
1640 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 9.6 in the year 1640 and 323.976 in 2025:

323.9769.6
×
$400,000,000,000,000
=
$13,499,000,000,000,000

$400,000,000,000,000 in 1640 has the same "purchasing power" or "buying power" as $13,499,000,000,000,000 in 2025.

To get the total inflation rate for the 385 years between 1640 and 2025, we use the following formula:

CPI in 2025 - CPI in 1640CPI in 1640
×
100
=
Cumulative inflation rate (385 years)

Plugging in the values to this equation, we get:

323.976 - 9.69.6
×
100
=
3,275%
