It's important to note that not all categories may be tracked since 1990. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 130.7 in the year 1990 and 252.146 in 2018:
$500 in 1990 has the same "purchasing power" or "buying power" as $964.60 in 2018.
To get the total inflation rate for the 28 years between 1990 and 2018, we use the following formula:
Plugging in the values to this equation, we get:
The above data describe the CPI for all items. Also of note is the Core CPI, which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 2.31% per year between 1990 and 2018 (vs all-CPI inflation of 2.70%), for an inflation total of 89.54%.
When using the core inflation measurement, $500 in 1990 is equivalent in buying power to $947.69 in 2018, a difference of $447.69. Recall that for All Items, the converted amount is $964.60 with a difference of $464.60.
In 1990, core inflation was 5.03%.
Politics and news often influence economic performance. Here's what was happening at the time:
Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (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.
