How to calculate inflation rate for $100, 2025 to 2026
Our calculations use the following inflation rate formula to calculate the change in value between 2025 and today:
CPI in 2025 CPI today
×
2026 USD value
=
Today's value
Then plug in historical CPI values. The U.S. CPI was 324.122 in the year 2026 and 321.05125 in 2025:
321.05125324.122
×
$100
=
$99.05
$100 in 2026 has the same "purchasing power" or "buying power" as $99.05 in 2025.
To get the total inflation rate for the 1 years between 2025 and 2026, we use the following formula:
CPI in 2025 - CPI in 2026CPI in 2026
×
100
=
Cumulative inflation rate (1 years)
Plugging in the values to this equation, we get:
321.05125 - 324.122324.122
×
100
=
-1%
Alternate Measurements of Inflation
There are multiple ways to measure inflation. Published rates of inflation will vary depending on methodology. The Consumer Price Index, used above, is the most common standard used globally.
Alternative measurements are sometimes used based on context and economic/political circumstances. Below are a few examples of alternative measurements.
Personal Consumption Expenditures (PCE) Inflation
The PCE Price Index is the U.S. Federal Reserve's preferred measure of inflation, compiled by the Bureau of Economic Analysis. It measures the change in prices of goods and services purchased by consumers.
For more information on the difference between PCE and CPI, see this analysis provided by the Bureau of Labor Statistics.
Chained Inflation
Chained CPI is an alternative measurement that takes into account how consumers adjust spending for similar items. In 2026, chained inflation was 2.14%.
