Can You Retire at 42 with $1.0M?

A complete retirement readiness assessment at age 42 with a $1,000,000 portfolio. See your 4% rule income, healthcare bridge costs, and Monte Carlo success probabilities.

Retiring at 42 with $1,000,000 means you'll need to fund 23 years of healthcare before Medicare kicks in at 65 — an estimated $220,800 bridge cost that could represent 22% of your portfolio. The 4% rule provides $3,333/month, but with a 91% 30-year success rate, you have a strong chance of your portfolio lasting. Early retirement requires careful healthcare planning and spending discipline — every additional year you delay substantially reduces the bridge cost and improves your success probability.

Calculation Assumptions

6% mean annual return with 13% volatility assumption.
3% annual inflation rate.
Monte Carlo simulation uses 6% return and 13% standard deviation (2000 simulations).
Healthcare bridge costs based on estimated ACA marketplace premiums; actual costs vary by state, age, and plan.
Retirement success defined as portfolio balance > $0 at end of horizon.
The 4% rule and safe withdrawal rates are guidelines, not guarantees. Past performance does not predict future results.
