What is $1 from 2011 worth today?
$1 in 2011 is worth $1.50 in September 2026, based on the official Consumer Price Index. Prices have risen 50% since 2011, an average of 2.69% a year over 15 years. In other words, prices have doubled about 0.6 times, and a dollar today buys 66.8% of what it bought in 2011.
The same ratio applies to any amount: $20 from 2011 is worth $29.96, $100 is worth $149.79 and $1,000 is worth $1,498 in today's dollars.
Inflation in 2011
The CPI-U averaged 224.939 in 2011, up 3.2% from 218.056 in 2010. From December 2010 to December 2011, prices rose 3.0%. Ranked by annual inflation, 2011 is number 45 of the 112 years from 1914 to 2025.
In the 2010s, annual inflation averaged 1.8% a year. The highest rate was 3.2% in 2011 and the lowest 0.1% in 2015, so 2011 had the decade's highest inflation.
2011 prices in today's money, and today's prices in 2011 money
If something cost $5 in 2011, the same buying power today is $7.49. Going the other way, $100 in September 2026 would have bought what $66.76 bought in 2011, and a $60,000 salary today has the buying power of a $40,056 salary in 2011.
If your pay in 2011 was, say, $1,000 a month, you would need about $1,498 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 2011 inflation figure is calculated
The calculation divides the latest CPI-U (336.94 for September 2026) by the 2011 annual average (224.939): 336.94 ÷ 224.939 = 1.4979. Multiply any 2011 amount by 1.4979 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.
