Historical conversions use BLS CPI-U annual averages; the latest year uses the most recent published index. Estimates only.
Inflation quietly rewrites the value of every dollar you hold. Using the official BLS Consumer Price Index, $1 in 2000 is worth about $1.93 today — prices are up roughly 93% in 26 years — and $1 from 1913 equals about $33.60 in 2026. The current U.S. inflation rate is 3.5% for the 12 months to June 2026. This calculator works both ways: convert historical amounts to today's money, or project forward to see what your savings will actually buy and the return required to stay ahead.
The short answer
The value of a dollar, decade by decade
Here is how far a single dollar from each era stretches in 2026 money, straight from the CPI. The further back you go, the more dramatic the erosion — a dollar from 1970 is worth more than eight of today's, while a dollar from 2020 has already lost nearly a quarter of its purchasing power.
| Year | $1 then = today | Cumulative inflation | Avg / year | $1 today buys (then) |
|---|---|---|---|---|
| 1913 | $33.64 | 3,264% | 3.16% | 3.0% |
| 1950 | $13.82 | 1,282% | 3.52% | 7.2% |
| 1970 | $8.58 | 758% | 3.91% | 11.7% |
| 1980 | $4.04 | 304% | 3.08% | 24.7% |
| 1990 | $2.55 | 155% | 2.63% | 39.2% |
| 2000 | $1.93 | 93% | 2.57% | 51.7% |
| 2010 | $1.53 | 53% | 2.68% | 65.5% |
| 2020 | $1.29 | 29% | 4.29% | 77.7% |
BLS CPI-U annual averages; end year 2026 (index 333.02 year-to-date; the latest monthly CPI was 333.952 in June 2026). The 2020 row's high average reflects the 2021–2022 spike, when inflation peaked at 9.1% (June 2022).
What your money will actually buy later
Inflation doesn't stop at today. Flip the calculator to forward mode to see the erosion ahead. The table below assumes 3% inflation on $100,000. The left column is what it will buy in today's dollars; the right is the larger nominal sum you'd need just to stand still.
| Years ahead | What $100,000 buys (today's $) | Nominal needed to keep pace |
|---|---|---|
| 5 years | $86,261 | $115,927 |
| 10 years | $74,409 | $134,392 |
| 20 years | $55,368 | $180,611 |
| 30 years | $41,199 | $242,726 |
At 3% annual inflation. Adjust the rate in the calculator to match your own assumption — the current rate is 3.5%.
The return you need to beat inflation
What matters for building wealth isn't the headline return — it's the real return, the slice left after inflation. The formula is (1 + nominal) ÷ (1 + inflation) − 1. At 3% inflation, here is what each option actually keeps. Cash goes backwards; only assets that out-earn inflation move you forward.
| Where the money sits | Nominal return | Real return (after 3% infl.) |
|---|---|---|
| Savings account | 0.38% | −2.54% |
| High-yield savings | 4.00% | +0.97% |
| US stock index (historic) | 10.00% | +6.80% |
| Just to break even | 3.00% | 0.00% |
Real return = (1 + nominal) ÷ (1 + inflation) − 1. Savings rate: FDIC national average 0.38% (Jul 2026). Stock return: S&P 500 ~10% nominal since 1928 (NYU Stern / Damodaran). At today's 3.5% inflation the break-even bar is even higher.
Why measures disagree: CPI vs core vs PCE
"Inflation" isn't a single number — different gauges tell slightly different stories, which is why headlines can seem to conflict. This calculator uses headline CPI-U, the standard for adjusting dollars over time, but it helps to know the alternatives:
- Headline CPI — all items, including food and energy. The rate you see in the news; 3.5% for June 2026. Best for converting historical dollar values.
- Core CPI — strips out volatile food and energy to show the underlying trend; 2.6% in June 2026. Since 2000 it averaged 2.38% a year versus 2.57% for all-items.
- PCE — the Federal Reserve's preferred gauge, from the Bureau of Economic Analysis. It weights spending differently and usually runs lower — about 2.19% a year since 2000, so $1 in 2000 equals $1.76 by PCE versus $1.93 by CPI.
For personal dollar conversions, headline CPI is the right tool; for reading where policy is heading, watch core and PCE alongside BeCoin's current market outlook.
Where inflation stands now
U.S. inflation cooled to 3.5% for the 12 months to June 2026 — down from 4.2% in May — as falling gasoline and energy prices dragged consumer prices down 0.4% on the month. Core inflation, excluding food and energy, was 2.6%. That is well below the 9.1% peak of June 2022 but still above the Federal Reserve's 2% target. The next CPI report, covering July, lands on August 12, 2026. Use the market outlook for current cross-asset context and the forex forecast for central-bank-sensitive currency scenarios.

All figures are computed client-side; no data is stored. Historical mode uses the identity value = amount × (CPIend ÷ CPIstart) with BLS CPI-U annual averages (1982–84 = 100) from 1913 to 2025 and the 2026 year-to-date index (333.02; the latest monthly CPI was 333.952 in June 2026). Cumulative inflation is CPIend ÷ CPIstart − 1; the average annual rate is the geometric mean over the span. Forward mode discounts and compounds by your assumed rate: future buying power = amount ÷ (1 + rate)years and nominal needed = amount × (1 + rate)years. Current rate: 3.5% for the 12 months to June 2026; core 2.6% (BLS, released Jul 14 2026). Alternate-measure figures (core CPI, PCE) are from BLS and the Bureau of Economic Analysis. Inflation figures are estimates of average price change and will not match any single household's experience.
