1935 Inflation Calculator
A hundred dollars in 1935 was serious money. Adjusted for inflation, it bought what $2,349.95 buys in 2025, the latest full year of Consumer Price Index data. Prices have risen about 23.5 times since then, which also means a modern dollar buys only about 4.3% of what a 1935 dollar bought.
The 1935 Inflation Calculator below converts any 1935 amount into the dollars of a later year using CPI-U annual averages from the Bureau of Labor Statistics. Every figure on this page uses one stated basis, CPI-U annual averages, with 1935 at 13.7 and 2025 at 321.943. Enter an amount, pick a target year, and click Calculate.
Quick Answer
Key takeaways
- $100 in 1935 = $2,349.95 in 2025 dollars; $1 in 1935 = $23.50 today.
- The math is one ratio: amount x (CPI of target year / CPI of 1935), using BLS CPI-U annual averages.
- Both endpoints use full-year averages, so the answer is stable and reproducible, unlike tools keyed to a partial current year.
- Average inflation ran about 3.6% a year across 1935-2025, and compounding is what turns that into a 23.5x price rise.

How much is $100 from 1935 worth in 2025 dollars?
The answer is $2,349.95, and it comes from a single division. The Bureau of Labor Statistics runs the Consumer Price Index for All Urban Consumers (CPI-U), which tracks the cost of a basket of goods and services. Its annual average was 13.7 in 1935 and 321.943 in 2025, both published in the BLS public data series for CPI-U (CUUR0000SA0). Divide the second number by the first and you get the price multiplier for the whole period.
Take the CPI ratio. 321.943 / 13.7 = 23.4995. Prices in 2025 averaged about 23.5 times their 1935 level.
Multiply the 1935 amount. $100 x 23.4995 = $2,349.95. That is the 2025 sum with the same purchasing power as $100 in 1935.
Read the cumulative rate. (23.4995 - 1) x 100 = 2,249.9%. That is the total percentage increase in prices, not an annual rate.
Worked example, checked against this exact tool
Enter the pre-filled defaults ($100, target year 2025) and click Calculate. Here is what the tool returns, verified against the underlying code:
| Figure | Value |
|---|---|
| Original amount (1935) | $100.00 |
| CPI-U ratio (321.943 / 13.7) | 23.4995 |
| Equivalent value in 2025 | $2,349.95 |
| Total increase | $2,249.95 |
| Cumulative inflation | 2,249.9% |
Scale it and the pattern holds: $1,000 in 1935 equals $23,499.49 in 2025, and $20 in 1935 equals $469.99. Run the ratio the other way and a 2025 $100 bill had the buying power of just $4.26 in 1935.
The CPI figures behind every target year
These are the exact BLS CPI-U annual averages the calculator uses, and what $100 in 1935 becomes in each year. The Federal Reserve Bank of Minneapolis CPI history table publishes the same series back to 1913:
| Target year | CPI-U | $100 in 1935 becomes |
|---|---|---|
| 1950 | 24.1 | $175.91 |
| 1960 | 29.6 | $216.06 |
| 1970 | 38.8 | $283.21 |
| 1980 | 82.4 | $601.46 |
| 1990 | 130.7 | $954.01 |
| 2000 | 172.2 | $1,256.93 |
| 2010 | 218.056 | $1,591.65 |
| 2020 | 258.811 | $1,889.13 |
| 2023 | 304.702 | $2,224.10 |
| 2024 | 313.689 | $2,289.70 |
| 2025 | 321.943 | $2,349.95 |
Why prices rose 23 times: the story behind the ratio
The 23.5x multiplier built up in uneven bursts, not a steady climb. In 1935 itself the economy was still in the Great Depression, and prices had actually fallen in the early 1930s before edging back up; inflation in 1935 itself was about 2.2%, with prices still near the 1933 trough. Prices fell again in a few later years: 1938 (about -2.1%), 1939 (about -1.4%), and 1949 (about -1.2%) all saw outright deflation, the kind of detail templated year tables bury. Wartime price controls in the 1940s suppressed inflation, which then broke loose after the war, and the biggest single burst came in the 1970s, when two oil shocks pushed annual inflation into double digits; the CPI more than doubled between 1970 and 1980 alone.
Across the full 90 years, prices rose at an average of about 3.6% per year. That sounds small until you compound it: 3.6% a year doubles prices roughly every two decades, and nine decades of doubling is what turns 13.7 into 321.943. It is also why the Federal Reserve's 2% inflation target exists: the Fed considers a low, steady rate healthier than either deflation or the volatile rates of the 1970s.
The practical lesson cuts both ways. Cash stored in 1935 kept its face value and lost about 95.7% of its buying power. Money that earned a return had a fighting chance: checking what growth actually delivered, net of that inflation, is what a S&P 500 returns calculator is for, and a high-yield savings calculator shows what even a modest interest rate does against the same drag. An annual time value of money calculator makes the same compounding visible year by year.
Why this answer differs from other calculators
Two honest calculators can disagree on 1935 conversions, and the reason is the endpoint. This tool uses full-year CPI-U annual averages on both ends, so the $2,349.95 figure is fixed and checkable against the published BLS series. Trackers that convert to "today" use a latest, part-year CPI instead (around 336.94), which is higher than any completed annual average and climbs almost every month; with that figure, the same $100 in 1935 comes out near $2,459. Neither number is fabricated, but only one of them is a finished measurement: the part-year figure will be revised into whatever 2026's full average turns out to be. For comparing against salaries, contracts, or historical prices, the stable annual figure is usually the better citation.
What competing inflation calculators miss
We checked the top-ranking 1935 inflation tools before writing this page. The gaps are consistent, and several are plain data problems:
The leader contradicts itself on one page. The ranking tracker (in2013dollars / Official Data) lists "Inflation in 2026" as 3.74% in its summary table and 4.58% in its own year-by-year table, two different current rates on the same page, and its S&P 500 real-return figures also differ between sections. This page prints one basis and one set of numbers, and the tool, the tables, and the text all agree.
A part-year figure dressed up as a finished year. The same leader converts with a "2026 CPI" of 336.94 that is a trailing, partial figure, not a completed annual average, without saying so plainly. Its equivalents will quietly change as the year completes. Ours uses the latest completed annual average (2025: 321.943) and labels it as such.
Stale pages still circulating. The same network still serves a 1935 page that ends in 2019, and another well-known CPI tool (calculators.org) discloses that its annual data ends in 2020 with later years "estimated." A searcher can land on either and never know. Every figure here is computed from the published BLS series, with the source one click away.
The BLS tool hides its own inputs. The Bureau of Labor Statistics' official calculator gives a number and nothing else: no CPI values, no cumulative rate, no way to check the work. Ours prints the exact CPI figures used (13.7 and 321.943) inside the result, plus the factor and the cumulative percentage.
Frequently asked questions
$100 in 1935 equals $2,349.95 in 2025 dollars, the latest complete year of BLS CPI-U annual averages. Prices are 23.50 times their 1935 level, a cumulative inflation of 2,249.9%.
Because 2025 is the latest year with a complete CPI-U annual average (321.943). Tools that convert to the current year use a partial, still-moving index, so their answer changes as new months arrive. Annual averages on both ends keep the result stable and reproducible.
$23.50 in 2025 dollars. One 1935 dollar had the purchasing power of about twenty-three and a half modern dollars.
About 2.2%. The CPI-U rose from 13.4 in 1934 to 13.7 in 1935, as prices recovered modestly from the deflation of the early Depression years, while remaining near the 1933 trough.
About 95.7%. A dollar today buys roughly 4.3% of what a 1935 dollar bought, because prices have risen 23.50 times over the period.
They use a latest, part-year CPI (around 336.94) instead of the 2025 annual average (321.943). Same formula, different endpoint, and the part-year figure is not a finished measurement. The annual-average figure stays fixed and citable.
No. This tool converts forward from 1935 only, to 1950 and later. Converting backward would need a different base year and its own CPI ratio.
