What is $1 from 2001 worth today?
$1 in 2001 is worth $1.90 in September 2026, based on the official Consumer Price Index. Prices have risen 90% since 2001, an average of 2.58% a year over 25 years. In other words, prices have doubled about 0.9 times, and a dollar today buys 52.6% of what it bought in 2001.
The same ratio applies to any amount: $20 from 2001 is worth $38.05, $100 is worth $190.25 and $1,000 is worth $1,903 in today's dollars.

2001 prices in today's money, and today's prices in 2001 money
If something cost $5 in 2001, the same buying power today is $9.51. Going the other way, $100 in September 2026 would have bought what $52.56 bought in 2001, and a $60,000 salary today has the buying power of a $31,537 salary in 2001.
If your pay in 2001 was, say, $1,000 a month, you would need about $1,903 a month in September 2026 to afford the same basket of goods and services. Remember that this is an average across consumer spending: some prices, such as housing, health care and tuition, have risen faster than the CPI, while others have risen more slowly.
How this 2001 inflation figure is calculated
The calculation divides the latest CPI-U (336.94 for September 2026) by the 2001 annual average (177.1): 336.94 ÷ 177.1 = 1.9025. Multiply any 2001 amount by 1.9025 to convert it to September 2026 dollars. The data is the CPI for All Urban Consumers, U.S. city average, all items, not seasonally adjusted (BLS series CUUR0000SA0), published by the U.S. Bureau of Labor Statistics.
