What this scenario works out to
In this example setup, the FIRE target comes to about $1,200,000. At this savings rate you could reach it around age 41. Stopping work at 40, the money runs low around age 94, so leave a safety margin.
These figures use this scenario’s example starting numbers — adjust the calculator above for your own situation.
Reading your retire-at-40 result
Hitting 40 as your FIRE age usually demands saving more than half your income, because compounding only has about 15 years to work. If the chart shows your money running out before your 90s, the two fastest levers are spending less in retirement (which lowers your target) or pushing the date back a few years. Small changes to your withdrawal rate or expected return move the finish line more than you would expect — try toggling them.
Who it fits: high earners or dedicated savers who can put away well over half their income for a decade or more, ideally starting in their twenties. It also suits people with low fixed costs and no near-term plans for a mortgage or children that would spike spending.
Watch out for: healthcare and the sheer length of the drawdown. Forty-plus years is a long time for inflation and a bad early market to bite, and most tax-advantaged accounts can't be touched penalty-free until your late fifties — plan a taxable bridge.

Common questions
- How much do I need to retire at 40?
- Roughly 25× your annual spending under the 4% rule. Lower your expenses and the target drops fast — halve your spending and you halve the number you need.
- Is retiring at 40 realistic?
- It is, with a high savings rate (often 50–70%) and a long runway of low-cost index investing. The earlier you start and the less you spend, the more achievable it becomes.
- What return rate should I assume?
- A conservative 5–7% real return is common for a diversified portfolio. A higher number flatters the plan — stress-test it with a lower figure before you commit.
