Between 1915 and 2025, US consumer prices rose by 3096.0%. That means $1 million then had roughly the same buying power as $31,960,396 now — an average of 3.20% inflation per year over 110 years.
What $1 million in 1915 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 1915 itself ran at 1.0%. 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 million in 1915 is equivalent in purchasing power to about $31,960,396 in 2025. That is an increase of $30,960,396 over 110 years, or a total price rise of 3096.0%.
Prices rose at an average of 3.20% per year between 1915 and 2025. Compounded over 110 years, that turns $1 million into $31,960,396.
The amount is multiplied by the ratio of the Consumer Price Index in 2025 to the index in 1915: 322.8 divided by 10.1 equals 31.9604. Multiplying $1 million by 31.9604 gives $31,960,396. 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, $1,000,000 in 2025 has roughly the same buying power as $31,289 in 1915.
