Early Retirement: Withdrawals, Health Coverage and Sequence Risk
Retiring before 59½ or 65 raises three problems: reaching retirement money without the 10% penalty, health coverage before Medicare, and sequence risk.
Early retirement means leaving paid work before the ages the US system is built around: 59½, when retirement accounts open without a penalty, and 65, when Medicare starts. Retiring earlier is mostly an exercise in bridging those two gaps while making a portfolio last longer than a standard retirement plan assumes. The money questions are which accounts you can draw from, what pays for health coverage, and how much you can safely withdraw each year.
Getting to your money before 59½
Withdrawals from a 401(k), 403(b) or IRA before age 59½ generally carry a 10% additional tax on top of ordinary income tax.1 The IRS lists exceptions, and two matter most for early retirees.
| Route | How it works | Where it fails |
|---|---|---|
| Separation from service at 55 or later ("Rule of 55") | Distributions from the employer plan are penalty-free if you leave that employer after reaching 551 | Does not apply to IRAs. Roll the 401(k) into an IRA and the exception is gone |
| Substantially equal periodic payments (often called 72(t)) | A fixed series of payments over your life expectancy avoids the penalty1 | Changing the payments before the later of five years or age 59½ brings back the 10% tax on every earlier payment, plus interest4 |
| Taxable brokerage account | No age rules at all; you pay capital gains tax on growth | Requires saving outside retirement accounts, which many plans neglect |
The practical rule: decide where your first ten years of spending will come from before you choose which account to fill next. People who put every dollar into a 401(k) sometimes reach their FI number on paper with nothing they can touch at 48.
Paying for health coverage until Medicare
Medicare eligibility generally begins at 65. The initial enrollment window lasts seven months, starting three months before the month you turn 65 and ending three months after it.2 Anyone retiring at 50 therefore needs 15 years of coverage from somewhere else.
The usual options are a spouse's employer plan, COBRA continuation (temporary and usually expensive), a retiree plan if your employer offers one, or a marketplace plan under the Affordable Care Act. Marketplace premium help is tied to income, not assets, which gives early retirees an unusual lever: how much income you choose to realize each year can change what you pay for insurance. The guide to health coverage before Medicare explains how premium tax credits are calculated for 2026 and which income counts.
Treat this as a budget line, not a footnote. A health premium that was invisible while an employer paid most of it often becomes one of the largest costs in the first years out of work.
How much you can withdraw, and for how long
The 4% figure comes from William Bengen's 1994 study, which found that a first-year withdrawal of 4%, raised each year with inflation, lasted at least 30 years across the historical periods he tested.3 An early retiree's horizon is often 40 to 50 years, which the original rule was not designed around.
The bigger threat is sequence risk: poor returns in the first years of withdrawals do far more damage than the same returns later, because you sell assets while prices are down and those shares never recover for you. Two retirees with identical average returns can end up in very different places depending on the order of those returns.
Common responses include starting below 4%, cutting spending after bad years (guardrail rules), holding a few years of spending in cash or bonds, and keeping some part-time income early on. The guide to the 4% rule compares these on what they cost and what they protect against.
Who this section is not for
If you are still building the savings, start with financial independence, which covers the target number and savings rate. If you are married, the timing of Social Security claims and a spouse's health plan change the math enough to read marriage and money alongside this section. And if your plan assumes market returns you have not checked, the basics of account types and fees are in on investing.
