Can You Retire at 58 with $500k?

A complete retirement readiness assessment at age 58 with a $500,000 portfolio. See your 4% rule income, healthcare bridge costs, and Monte Carlo success probabilities.

At 58 with $500,000, you face a 7-year healthcare bridge to Medicare (estimated $67,200 total), and the 4% rule provides $1,667/month. With a 92% 30-year Monte Carlo success rate, your portfolio has a strong probability of lasting through retirement. The bridge to Medicare and your overall withdrawal strategy should account for sequence of returns risk, especially in the first 5-10 years of retirement.

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.
