The Moment
Early retirement is appealing because it compresses the timeline. It is also more demanding than standard retirement planning because the portfolio must last longer, healthcare must be self-funded for more years, and there is less room for error in the early sequence of returns.
The Short Answer
Test early retirement as a balance-sheet and cash-flow problem, not a lifestyle aspiration.
A strong feasibility review asks: 1. how long the portfolio must last 2. what the sustainable withdrawal rate is over that horizon 3. how healthcare will be funded before Medicare eligibility 4. whether the plan survives a poor early sequence of returns
Why This Matters
Early retirement amplifies every retirement planning risk. A longer horizon means more compounding of errors. Healthcare before Medicare is expensive and variable. Sequence risk is most dangerous in the first decade of withdrawals. A plan that looks comfortable at average assumptions can fail under realistic stress.
Decision Logic
If the withdrawal rate is low enough to survive a decade of poor returns, the plan is stronger. If healthcare costs are not explicitly modeled, the plan is incomplete. If the portfolio depends on average returns throughout, it is fragile. If there is flexibility in spending, the plan can adapt. If there is no flexibility, the margin for error must be larger.
Common Mistakes
Using average return assumptions without stress-testing the early years. Underestimating healthcare costs before Medicare. Setting a withdrawal rate that works in good markets but fails in bad ones. Treating early retirement as a one-way door without a contingency plan.
What Changes the Answer
Portfolio size, withdrawal rate, retirement age, healthcare costs, spending flexibility, and the sequence of early returns.

- →What is my contingency if the plan needs to be adjusted in year three?
Frequently Asked Questions
What withdrawal rate is safe for early retirement?
Lower than for standard retirement. A longer horizon means more exposure to sequence risk and inflation, which argues for a more conservative rate.
How do I handle healthcare before Medicare?
It needs to be explicitly budgeted. Marketplace plans, COBRA, or spouse coverage are options, but costs are significant and variable.
What is the biggest early retirement mistake?
Building a plan that works at average assumptions but has no room to adapt when early years are weak.
