1984 prices in today's money, and today's prices in 1984 money
If something cost $5 in 1984, the same buying power today is $16.21. Going the other way, $100 in September 2026 would have bought what $30.84 bought in 1984, and a $60,000 salary today has the buying power of a $18,502 salary in 1984.
If your pay in 1984 was, say, $1,000 a month, you would need about $3,243 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 1984 inflation figure is calculated
The calculation divides the latest CPI-U (336.94 for September 2026) by the 1984 annual average (103.9): 336.94 ÷ 103.9 = 3.2429. Multiply any 1984 amount by 3.2429 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.
