Compare these numbers to the US's overall absolute change of $9,573.81 and total percent change of 2,393.45%.


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 1800 and 2024.

Compare these values to the overall average of 1.45% per year:

How to calculate inflation rate for $400 since 1800

Our calculations use the following inflation rate formula to calculate the change in value between 1800 and today:

CPI today CPI in 1800
×
1800 USD value
=
Today's value

Then plug in historical CPI values. The U.S. CPI was 12.6 in the year 1800 and 314.175 in 2024:

314.17512.6
×
$400
=
$9,973.81

$400 in 1800 has the same "purchasing power" or "buying power" as $9,973.81 in 2024.

To get the total inflation rate for the 224 years between 1800 and 2024, we use the following formula:

CPI in 2024 - CPI in 1800CPI in 1800
×
100
=
Cumulative inflation rate (224 years)

Plugging in the values to this equation, we get:

314.175 - 12.612.6
×
100
=
2,393%
