What is $1 from 2015 worth today?
$1 in 2015 is worth $1.42 in September 2026, based on the official Consumer Price Index. Prices have risen 42% since 2015, an average of 3.19% a year over 11 years. In other words, prices have doubled about 0.5 times, and a dollar today buys 70.3% of what it bought in 2015.
The same ratio applies to any amount: $20 from 2015 is worth $28.43, $100 is worth $142.16 and $1,000 is worth $1,422 in today's dollars.
Inflation in 2015
The CPI-U averaged 237.017 in 2015, up 0.1% from 236.736 in 2014. From December 2014 to December 2015, prices rose 0.7%. Ranked by annual inflation, 2015 is number 97 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 2015 had the decade's lowest inflation.
2015 prices in today's money, and today's prices in 2015 money
If something cost $5 in 2015, the same buying power today is $7.11. Going the other way, $100 in September 2026 would have bought what $70.34 bought in 2015, and a $60,000 salary today has the buying power of a $42,206 salary in 2015.
If your pay in 2015 was, say, $1,000 a month, you would need about $1,422 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 2015 inflation figure is calculated
The calculation divides the latest CPI-U (336.94 for September 2026) by the 2015 annual average (237.017): 336.94 ÷ 237.017 = 1.4216. Multiply any 2015 amount by 1.4216 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.
