Between 1925 and 2025, US consumer prices rose by 1744.6%. That means $100,000 then had roughly the same buying power as $1,844,571 now — an average of 2.96% inflation per year over 100 years.
What $100,000 in 1925 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 1925 itself ran at 2.3%. 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.
$100,000 in 1925 is equivalent in purchasing power to about $1,844,571 in 2025. That is an increase of $1,744,571 over 100 years, or a total price rise of 1744.6%.
Prices rose at an average of 2.96% per year between 1925 and 2025. Compounded over 100 years, that turns $100,000 into $1,844,571.
The amount is multiplied by the ratio of the Consumer Price Index in 2025 to the index in 1925: 322.8 divided by 17.5 equals 18.4457. Multiplying $100,000 by 18.4457 gives $1,844,571. 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, $100,000 in 2025 has roughly the same buying power as $5,421 in 1925.
