What $1 from 1990 buys across the decades
| Year | CPI-U | $1 in 1990 equals |
|---|---|---|
| 1990 | 130.7 | $1.00 |
| 2000 | 172.2 | $1.32 |
| 2010 | 218.1 | $1.67 |
| 2020 | 258.8 | $1.98 |
| 2024 | 313.7 | $2.40 |
Every column uses the CPI-U annual average, the broadest and most widely cited version of the index. The right-hand figure shows how much money you'd need in that year to match what $1 bought back in 1990; enter your own amount and years in the calculator above to run the identical lookup on a number that matters to you.
The conversion, one step
Equivalent value equals your amount times the end-year CPI, divided by the start-year CPI. For $1,000 moving from 1990 to 2024: the CPI-U annual average was about 130.7 in 1990 and about 313.7 in 2024, so 1,000 times 313.7 divided by 130.7 comes out near $2,400. That's total inflation of roughly 140 percent across 34 years, or an average of about 2.6 percent a year once spread evenly, even though no single year actually ran at exactly that pace.
Which CPI series, and why it matters
The BLS publishes several CPI variants. This tool uses CPI-U, for All Urban Consumers, the version most commonly cited in the media and in most cost-of-living discussions. A coworker's app or a different tool might use CPI-W, a narrower series covering wage earners and clerical workers, or the chained CPI used in some federal calculations, any of which will produce a slightly different number for the identical two years. None of them is wrong; they're measuring related but distinct baskets.
What inflation doesn't do evenly
A single national average hides a lot of variation underneath it. Housing, energy, and food can move sharply differently from the headline number in any given year, which is part of why "inflation is X percent" can feel disconnected from a specific household's actual grocery or rent bill. The annual-average approach used here smooths some of that further still, so for a month-specific or category-specific figure, the BLS's own calculator is the more precise tool.
