Between 2015 and 2025, US consumer prices rose by 36.2%. That means $1 then had roughly the same buying power as $1.36 now — an average of 3.14% inflation per year over 10 years.
What $1 in 2015 was worth at each following decade, adjusted for consumer price inflation.
Inflation adjustment uses the ratio of the Consumer Price Index between the two years — the same method the U.S. Bureau of Labor Statistics documents for comparing dollar amounts over time.
The index used is CPI-U (all urban consumers, US city average, all items), base period 1982-1984 = 100. Inflation in 2015 itself ran at 0.1%. The 2025 figure is the latest annual average available and may be revised by BLS.
Note: other inflation calculators may show slightly different results because some use a specific month rather than the annual average, or a different end year. This page uses annual averages throughout, and states both index values above so the arithmetic can be checked.
$1 in 2015 is equivalent in purchasing power to about $1.36 in 2025. That is an increase of $0.36 over 10 years, or a total price rise of 36.2%.
Prices rose at an average of 3.14% per year between 2015 and 2025. Compounded over 10 years, that turns $1 into $1.36.
The amount is multiplied by the ratio of the Consumer Price Index in 2025 to the index in 2015: 322.8 divided by 237.0 equals 1.3619. Multiplying $1 by 1.3619 gives $1.36. The index is the CPI-U published by the U.S. Bureau of Labor Statistics, base period 1982-1984 = 100.
Running the comparison in reverse, $1.00 in 2025 has roughly the same buying power as $0.73 in 2015.
