Can I Retire at 42 with $1 Million?
We simulated 5,000 different market scenarios to see how often your money lasts with $40,000/year spending. 56% of the time, it does — all the way to age 95.
What if you spent less or more? Three scenarios show how spending level affects your odds.
| Scenario | Withdrawal | Success |
|---|---|---|
| Lower spending (80%) | $32k/yr | 79% |
| Base case | $40k/yr | 56% |
| Higher spending (125%) | $50k/yr | 31% |
Starting with $1M at age 42. 75/25 stock/bond allocation. All values in today's dollars. Success = portfolio not depleted by age 95.
How did this plan do in real history?
Using 1871–2025 market data, we simulated 103 overlapping 53-year sequences — each starting one year apart. It survived 87% of them.

Bridge years: age 42 to Medicare at 65
Retiring at 42 means covering 23 yearsof health insurance before Medicare eligibility kicks in at 65. Without an employer plan, households typically shop the ACA marketplace, where premiums vary widely by age, geography, household composition, and subsidy eligibility — the Modified Adjusted Gross Income threshold for ACA subsidies is a common planning lever during the bridge years. Healthcare is often the single largest variable spending item in early retirement and is not included in the $40,000/year baseline this page simulates.
Households retiring this early also need a strategy for the gap before Social Security (25 years away at full retirement age 67) and before penalty-free traditional retirement account access at 59½. Common approaches include a separate cash or short-duration bond bucket for the first few years of retirement spending, a Roth conversion ladder started years before withdrawals begin, or Rule 72(t) substantially-equal periodic payments. Claiming Social Security before age 62 is not an option.
This simulation does not model Social Security, healthcare-specific inflation, or tax-advantaged account access rules. Run a Traditional plan on the dashboard to layer those in.
Insights
▲Withdrawal rate above standard benchmarks
The implied withdrawal rate is 4.0%. For early retirement horizons of 40+ years, research suggests 3.25–3.5% as a more conservative target.
▲Moderate simulated success rate
The base scenario shows a 56% success rate. Many financial planning studies consider 75–90% a reasonable confidence range. Small adjustments to contributions, spending, or timing may improve outcomes. The reduced-spending scenario showed 79% success.
