Coast FIRE with $3 million
At every age from 25 to 55, $3 million is Coast FIRE for up to $100,000 a year of retirement spending. For most people with this much, the question is whether they need to work at all.

What $3M pays for at 65
If you add nothing more and leave $3,000,000 invested until 65, this is the yearly spending it supports, in today's dollars.
| Your age now | Balance at 65 | Spending at 3.5% | Spending at 4% |
|---|---|---|---|
| 25 | $13,771,567 | $482,005 | $550,863 |
| 30 | $11,382,839 | $398,399 | $455,314 |
| 35 | $9,408,445 | $329,296 | $376,338 |
| 40 | $7,776,516 | $272,178 | $311,061 |
| 45 | $6,427,651 | $224,968 | $257,106 |
| 50 | $5,312,752 | $185,946 | $212,510 |
| 55 | $4,391,236 | $153,693 | $175,649 |
Growth is 7% a year before inflation and 3% inflation, about 3.88% a year after it. Social Security and any pension come on top.
Is $3M already Coast FIRE?
"Yes" means $3,000,000 grows to your full FIRE number (spending divided by 4%) by 65 on its own. Otherwise the cell shows the age you'd cross the line if you kept adding $1,000 a month.
| Your age now | $40K a year | $60K a year | $80K a year | $100K a year |
|---|---|---|---|---|
| 25 | Yes | Yes | Yes | Yes |

Calling $3 million “Coast FIRE” undersells it. At 44, a Coast FIRE number for a $120,000 retirement is less than half of that, so most people with this balance could stop saving today, or stop working soon. What’s left are fat FIRE questions, mostly about how much you can safely spend and how much of your money sits in one company’s stock.
Who has $3 million?
Usually high earners in their 40s and 50s: physicians, senior people in tech and finance, lawyers, and business owners who sold or built something. A lot of them got there partly through equity pay, which means a big share of the balance is in one company. It’s a long way from typical. The Fed’s 2022 Survey of Consumer Finances puts the median retirement balance for families aged 55 to 64 who had one at $185,000.
Yusuf: past coasting, deciding whether to stop
Yusuf is 44, a product director at a software company, with $3,000,000 spread across his 401(k), a brokerage account and vested company stock. He expects to spend $120,000 a year. His Coast FIRE number is $1,347,856. He passed it years ago.
If he stopped contributing and left the money alone until 65, it would grow to about $6,677,269 in today’s dollars, more than twice his $3,000,000 FIRE number. That’s the fat FIRE trap in one line: keep working at full pace here and you end up with far more than you’ll ever spend.
He’s also already at his FIRE number, if he’s happy with a 4% withdrawal rate. I’d want him to use 3.5%, since a retirement starting at 44 could last 50 years. In William Bengen’s 1994 paper, rates up to about 3.5% lasted at least 50 years in every period he tested. At 3.5% his target is $3,428,571, and without adding a dollar he gets there at about 48.
So his real choice is between stopping now on $105,000 a year or working about four more years for the full $120,000. Either is sensible. Working at the same intensity until 60 isn’t.
Yusuf's numbers

How much is in one stock?
This is where I’d spend Yusuf’s first hour. Say $1.2 million of his $3 million is his employer’s shares. A 50% drop in that one stock, which happens to large, well-known companies, would take $600,000 off his net worth, and it could arrive at the same moment as a layoff. FINRA’s note on concentration risk explains why that pairing is worse than it looks.
Selling a concentrated position in a taxable account means paying capital gains tax, and that’s the usual reason people hold on. I’d still set a schedule and sell down over a few years. Paying some tax on a gain is a better outcome than keeping a fortune tied to one company’s next five years.
The estate question, briefly
At $3 million the federal estate tax isn’t a problem for most people: the 2026 basic exclusion is $15 million per person. Some states set the bar far lower. Massachusetts, for one, taxes estates over $2 million, and a Coast FIRE balance that keeps compounding can cross a state threshold like that without the owner noticing.
The cheaper work is paperwork. Up-to-date beneficiary designations on every 401(k) and IRA, a will, and a decision about how much you actually want to leave behind will do more at this size than any clever tax move. That last decision also tells you how much you can spend, which brings you back to the choice Yusuf is facing.
When Coast FIRE still helps at $3 million
It’s a useful floor. If Yusuf wants to leave tech and run a small business that might pay him nothing for three years, the Coast FIRE number tells him how much of his portfolio has to stay untouched for 65 to be safe. On these assumptions, everything above $1,347,856 is money he can take risks with. The Fat FIRE calculator handles the full-retirement version of the question, and Coast FIRE vs. Fat FIRE compares the two goals directly.
Other balances: Coast FIRE with $100K, Coast FIRE with $200K, Coast FIRE with $300K, Coast FIRE with $500K, Coast FIRE with $1M. You can compare them all on one page, or see the Coast FIRE number by age from 20 to 60.
Questions people ask
Is $3 million enough to retire early?
For most budgets, yes. At a 4% withdrawal rate it supports $120,000 a year, and at 3.5%, a safer rate for a retirement that could last 50 years, about $105,000. Taxes and, before 65, health insurance come out of that figure.
What will $3 million grow to by 65?
With 7% returns and 3% inflation and nothing added, about $6.4 million in today's dollars from age 45 and about $4.4 million from 55. That's a middle case. A poor decade early on would leave you with much less.
Do I need to worry about estate tax with $3 million?
Not federally, for most people. The 2026 federal basic exclusion is $15 million per person. Some states tax much smaller estates, though; Massachusetts, for example, taxes estates over $2 million, so where you live matters.
