Can You Retire at 55 with $1.0M?

A complete retirement readiness assessment at age 55 with a $1,000,000 portfolio. See your 4% rule income, healthcare bridge costs, and Monte Carlo success probabilities.

At 55 with $1,000,000, you face a 10-year healthcare bridge to Medicare (estimated $96,000 total), and the 4% rule provides $3,333/month. With a 91% 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.
