Inflation Calculator: What's a Dollar Worth Today?
Use this inflation calculator with official CPI data from the U.S. Bureau of Labor Statistics to translate any dollar amount from 1913 through 2025 into today's equivalent — or check whether your raise actually kept up with inflation. Includes a homeowner-specific view that strips shelter costs from the CPI.
How Much Is $1 From Any Year Worth Today?
Every dollar loses purchasing power when prices rise over time. A dollar in 1950 could buy roughly the same goods and services that cost about $13.36 today — not because the bill changed, but because the basket of things it could buy became more expensive. The Consumer Price Index (CPI), published monthly by the U.S. Bureau of Labor Statistics, measures that change. This calculator uses the official CPI-U (All Urban Consumers) annual average series — CUUR0000SA0 — with data running from 1913 through 2025, to translate any dollar amount across any two years.
The calculation is straightforward: divide the CPI for the end year by the CPI for the start year, then multiply by your original dollar amount. A $1,000 figure from 1980 (CPI: 82.4) has the same purchasing power as roughly $3,906 in 2025 (CPI: 321.9). That comparison matters when you're evaluating historical returns, setting a retirement budget, or benchmarking compensation over time.
Is Your Raise Actually a Raise?
A 4% salary increase sounds meaningful — until you check that inflation ran at 7% during the same period. In real terms, that's a purchasing-power decline of nearly 2.8%. The "Is This a Real Raise?" tab runs this calculation for any two years in the BLS dataset. Enter your old and new salaries and the years each applied to; the calculator shows your nominal raise percentage and your real (inflation-adjusted) raise percentage side by side.
This was especially consequential during 2021–2023, when many workers received double-digit nominal raises that still left them behind the CPI surge. If your real raise number is negative, your paycheck grew but your purchasing power shrank.
Homeowners: Why Headline Inflation Overstates What You Feel
The shelter component — rent and owners' equivalent rent — typically accounts for roughly a third of the headline CPI-U. For renters, that weight is appropriate: their housing costs genuinely rise with the market. For homeowners with fixed-rate mortgages who plan to stay put, it's a different story. Their principal and interest payment is locked in and doesn't move with inflation.
The "Exclude Housing (Shelter)" toggle switches the calculator to the BLS CPI-U All Items Less Shelter series (CUUR0000SA0L2), published since 1935. This approximates the inflation that fixed-rate homeowners actually feel across food, energy, healthcare, transportation, and other everyday spending. It's not a complete picture — property taxes, insurance, maintenance, and utilities still rise — but it's a meaningfully different number from the headline rate during periods when rent is surging.
Frequently Asked Questions
The Consumer Price Index (CPI) is a measure of the average change in prices paid by urban consumers for a market basket of goods and services, published monthly by the U.S. Bureau of Labor Statistics. This calculator uses the CPI-U (All Urban Consumers) annual average series — series CUUR0000SA0 — with data running from 1913 through 2025. To find the inflation-adjusted value of any dollar amount, it divides the end-year CPI by the start-year CPI and multiplies by the original amount. When the Exclude Housing toggle is on, it uses the CPI-U All Items Less Shelter series (CUUR0000SA0L2) instead.
No. When you enable the "Include future years" option, the calculator extends the end-year range beyond 2025 using an assumed annual rate you set — not an economic forecast. The default assumption is 2.5% per year, but you can change it to any figure that makes sense for your planning. Future-year results are clearly labeled as projections, not forecasts, so there is no risk of mistaking a user-supplied assumption for a BLS data point.
The standard view uses the headline CPI-U, which covers all spending categories including food, energy, medical care, and shelter. The "Exclude Housing" view switches to the BLS CPI-U All Items Less Shelter series, which removes the rent and owners' equivalent rent components. This is useful for homeowners with fixed-rate mortgages, because their housing payment doesn't rise with CPI — so the headline rate overstates the inflation they actually feel on everyday spending.
Use the "Is This a Real Raise?" tab to find out. Enter your old salary, new salary, and the years each applied to. The calculator shows your nominal raise percentage alongside your real (inflation-adjusted) raise percentage. If the real figure is negative, your purchasing power declined even though your paycheck grew. For example, a 5% raise during a period of 7% cumulative inflation works out to roughly a 1.9% real pay cut.
The BLS did not publish a separate "All Items Less Shelter" CPI series before 1935. The headline CPI-U data extends back to 1913, but the housing-excluded series (CUUR0000SA0L2) only has verified BLS data starting in March 1935. If you have a pre-1935 start year selected when you flip the Exclude Housing toggle on, the calculator automatically resets the start year to 1935 and displays a brief note explaining why the range changed.
No. This calculator is an educational tool that uses historical CPI data from the U.S. Bureau of Labor Statistics. It does not constitute financial, tax, or investment advice. Future projections shown when the "Include future years" option is enabled are based on a user-supplied assumption, not an economic forecast.

How much do you actually need in retirement — in today's dollars?
Inflation compounds across every year of accumulation and every year of drawdown. RetireSmart factors in CPI so your FIRE number reflects what spending actually costs, not what it cost when you set the goal.
