How much money do I need to retire at 50?
To retire at 50, most people need 30–33x their annual expenses — roughly $1.5M to $2.5M for those spending $50,000–$75,000 per year. A 40-year retirement horizon requires a slightly more conservative withdrawal rate of 3.3%–3.5% rather than the standard 4%.
Formula
Retirement Number = Annual Expenses × 29 to 33 (use 33x for aggressive growth assumptions, 29x for conservative)
Example
You spend $70,000 per year and want to retire at 50. Using 30x: $70,000 × 30 = $2,100,000. At a 3.33% withdrawal rate, your $2.1M portfolio produces $70,000 annually and has historically survived 40-year periods in most market scenarios.
How it works in detail
Retiring at 50 means funding a retirement that could last 40–45 years, which meaningfully changes the math compared to retiring at 65. The classic 4% rule, derived from William Bengen's 1994 research and reinforced by the Trinity Study, was designed for 30-year retirements. For a 40-year horizon, research by Wade Pfau and Michael Kitces suggests a safer withdrawal rate is closer to 3.3%–3.5%, which implies a savings target of 29x–30x annual expenses. For someone spending $60,000 per year, that means needing approximately $1.7M–$1.8M. At $80,000 annual spending, the target rises to $2.3M–$2.4M. Retiring at 50 also introduces unique planning challenges beyond the portfolio size. You face a 9.5-year gap before Medicare eligibility at 59½ for penalty-free 401(k) access (though the Rule of 55 applies to some plans), and a 12-year gap before Medicare at 62. Healthcare costs alone can run $700–$1,200 per month before Medicare and must be explicitly budgeted. Social Security will be reduced by decades of lower reported earnings. Most early retirees at 50 supplement portfolio withdrawals with Roth conversions, taxable brokerage accounts, and rental income to bridge these gaps. A Roth conversion ladder started immediately at retirement can create penalty-free access to pre-tax funds within 5 years.

What is a safe withdrawal rate for early retirement (40+ years)?
For retirements lasting 40+ years, research suggests 3.25–3.5% is safer than the traditional 4%. A $2M portfolio at 3.5% provides $70,000/year. With dynamic spending (cutting 10–15% in down markets), you can safely withdraw 4–4.5% even over 50 years.
How much does healthcare cost if I retire before 65?
ACA marketplace coverage for an early retiree costs $400–$1,500/month per person ($5,000–$18,000/year) depending on age, location, and income. A couple retiring at 55 should budget $12,000–$25,000/year until Medicare at 65. ACA subsidies dramatically reduce costs if Modified AGI stays below $77,000 (single) or $103,000 (couple).
What is the Rule of 55 and how does it work for early retirement?
The Rule of 55 lets you withdraw from your current employer's 401(k) penalty-free starting at age 55 if you leave that job in or after the calendar year you turn 55. It avoids the normal 10% early-withdrawal penalty, though withdrawals are still taxed as ordinary income.
