Yes — comfortably into Fat FIRE territory. At 65, $4 million plus Social Security funds an affluent lifestyle the portfolio sustains indefinitely for most spending levels.

How long will $4M last?
How long the money lasts comes down to one thing: how much you take out each year. Here's how long $4M lasts on its own — before Social Security — if it earns about 1.9% a year after inflation:
| If you spend | That's | Money lasts |
|---|---|---|
| $120,000/yr | 3% a year | 50+ yrs |
| $160,000/yryour plan | 4% a year | 34 yrs |
| $200,000/yr | 5% a year | 25 yrs |
This is your savings alone — Social Security makes it last even longer. Spend less and it can last for good; spend more and it runs out faster.
One more thing the numbers can't show: where you live. The same $4M goes much further in the Midwest or South than in an expensive coastal city. If you're open to moving, your money effectively stretches further.
The 6 things that decide the answer
Whether $4M is “enough” depends on your life, not a magic number. These six things move the answer most — the calculator handles the first four.
1 · How much you spend. By far the biggest factor. A $45,000 life and a $75,000 life are the difference between the money lasting for good and running out in your 80s.
2 · When you retire. Every year earlier is a year more of spending and a year less of growth — plus a longer wait for Social Security and Medicare.
3 · Social Security. A paycheck for life that rises with inflation. Waiting until 70 instead of 62 makes it over 75% bigger — and every dollar it pays is one you don't pull from savings.
4 · Health insurance before 65. Retire early and you buy your own until Medicare starts — often $1,000+ a month per person. It's the most-forgotten cost; add it to your spending.
5 · Bad timing. A market drop in your first few retired years hurts far more than one later, because you're selling while prices are low. Keep some cash and stay flexible.
6 · Taxes. A pre-tax million isn't a spendable million — money pulled from a 401(k) is taxed as income. This tool uses pre-tax, today's dollars, so treat the result as a starting point.
Is $4M the right number for you?
$4 million is comfortably into Fat FIRE — a $160,000–$180,000 lifestyle that the portfolio funds without strain, often growing even as you spend. For essentially everyone the money lasts; the interesting question is what you want it to do.
The planning is almost entirely tax and structure. Big traditional balances drive large RMDs and bracket creep in your 70s; Roth conversions, asset location, and charitable strategies (donor-advised funds, qualified charitable distributions) are where real dollars are won or lost at this level.
And $4M usually means a standing surplus and an estate — so the plan is as much about heirs, gifting, and the legacy you want as it is about your own spending. Set the calculator to your actual lifestyle; the large ending balance is the part to direct intentionally.

Methodology & assumptions
This isn't a rule of thumb — it's a year-by-year simulation. Each year it subtracts what you spend (minus Social Security), grows what's left, and checks whether the money reaches your planning age. The defaults are deliberately cautious:
- 5% nominal return — a retiree's de-risked mix of stocks and bonds, not an all-equity portfolio.
- 3% inflation — so every figure stays in today's dollars (about 1.9% real).
- Age 95 planning horizon — plan long; outliving the money is the costly error.
- 4% withdrawal rate — the Trinity Study baseline, used for the 4%-rule option and the longevity table. The engine itself depletes year by year rather than assuming a flat draw.
- Social Security is treated as an inflation-adjusted income stream from its start age — get your real estimate from ssa.gov. All figures are pre-tax and in today's dollars.

Educational, not financial advice. Markets don't deliver a steady return, sequence-of-returns risk is real, and taxes depend on your accounts and state. Use this to build intuition and frame the question — not as a plan to act on without advice tailored to your situation.
