Retirement in Today's Dollars Calculator
Convert a future retirement amount into today’s purchasing power using a simple inflation assumption.
Nominal vs real thinking
A retirement target that looks large in nominal dollars can feel much smaller once you adjust for inflation. That is why future-value pages should be paired with a real-value check.
This page helps you avoid one of the most common planning mistakes: assuming a future million will buy what a million buys now.
Use this with your retirement plan
Start with a future balance estimate, then translate it into today’s dollars. After that, compare the result with your expected lifestyle costs instead of staring at a raw headline number.
What a future balance is actually worth
Every projection on this site, and almost every projection anywhere, is quoted in future money. Inflation means that future money buys less. Converting back to today's purchasing power is a single division, and it changes how a number feels more than any other adjustment.
| Future balance | In 20 years' money | In 30 years' money | In 40 years' money |
|---|---|---|---|
| $250,000 | $152,568 | $119,186 | $93,108 |
| $500,000 | $305,135 | $238,371 | $186,215 |
| $1,000,000 | $610,271 | $476,743 | $372,431 |
| $2,000,000 | $1,220,542 | $953,485 | $744,861 |
At 2.5% average inflation. Divide by (1 + inflation)years.
A million dollars in thirty years has roughly the purchasing power of $476,743 today at 2.5% inflation. At 3% it is closer to $411,987. Neither figure makes the million useless — it makes it a different number from the one people picture when they set the target.
People argue endlessly about whether to model 6% or 8%, then quote the answer in future dollars as though it were spendable today. The inflation adjustment is larger than the difference between most rate assumptions, and it is far more certain to happen.
Two ways to handle it, one of which is easier
- Project nominally, then deflate. Use your usual nominal return, then divide the result by (1 + inflation)years. Easiest to check, because the intermediate figure matches other calculators.
- Project with a real rate. Use (1 + nominal) ÷ (1 + inflation) − 1 as the rate, and the output is already in today's money. Fewer steps, but the intermediate number will not match anything else you look at.
- Do not subtract inflation from the rate. It is close at low rates and wrong enough to matter over decades — nominal vs real return prices the error.
- Set the target in today's money too. Deciding you need $60,000 a year and then comparing it to a nominal projection is the mistake this page exists to prevent.
Contributions add a further wrinkle. If your deposits stay flat in nominal terms, they shrink in real terms every year — a $500 monthly contribution has considerably less purchasing power in year thirty than in year one. Increasing contributions roughly in line with inflation keeps the plan's real shape intact.
Questions about inflation-adjusted retirement
How do I adjust a retirement projection for inflation?
Divide the projected balance by (1 + inflation)years. At 2.5% over 30 years that means dividing by about 2.10.
What inflation rate should I use?
Many long-term plans use 2% to 3%. Using a slightly higher figure than you expect is the conservative error, since it understates rather than overstates what your money will buy.
Is $1 million enough to retire?
In today's money it supports roughly $40,000 a year at a 4% withdrawal rate. In thirty years' money the same million has the purchasing power of about $476,743, supporting closer to $19,070 a year in current terms.
Should I increase my contributions over time?
If you can. A flat contribution loses real value every year. Increasing deposits with inflation keeps the plan's purchasing power on track rather than quietly eroding it.
