Medicare Eligibility & Enrollment
Medicare is the federal health insurance program for Americans age 65 and older. Key enrollment windows and costs sourced from CMS.
Medicare eligibility begins at age 65 for most Americans. The Initial Enrollment Period (IEP) is a 7-month window — 3 months before, the month of, and 3 months after your 65th birthday. Missing this window results in a permanent 10% late enrollment penalty per 12 months for Part B (medical insurance).

Withdrawal Rules & Safe Withdrawal Rates
How much can you withdraw each year without running out of money?
The 4% Rule (Bengen, 1994): Withdraw 4% of your portfolio in year one, then adjust for inflation each year. Research shows this historically sustains a portfolio for 30 years with high probability. For a $1,000,000 portfolio, that's $40,000/year or $3,333/month.
Required Minimum Distributions (RMDs): Under SECURE 2.0, the RMD starting age increased to 73 (for those who turned 72 after December 31, 2022) and will rise to 75 for those born in 1960 or later. Failure to take RMDs results in a 25% excise tax on the shortfall.
Safe Withdrawal Rate Research Summary
Academic consensus| Rate | Retirement Duration | Historical Success Rate | Notes |
|---|---|---|---|
| 4.0% | 30 years | ~95% | Bengen (1994); widely used benchmark |
| 3.5% | 35 years | ~95% | Recommended for early retirees |
| 3.3% | 40 years | ~95% | Pfau & Kitces (2013) for FIRE |
| 5.0% | 20 years | ~90% | Higher rate appropriate for shorter retirement |

When does Medicare coverage begin?
Medicare eligibility begins at age 65 for most Americans. The Initial Enrollment Period (IEP) is 7 months: 3 months before, the month of, and 3 months after your 65th birthday. The standard Part B premium in 2025 is $185.00/month. Missing the IEP without qualifying for a Special Enrollment Period results in a permanent 10% late enrollment penalty per 12-month period missed. Source: CMS.gov.
How much do I need to retire comfortably?
Using the 4% safe withdrawal rule, you need 25 times your annual expenses beyond Social Security and pension income. Example: If you need $60,000/year from savings, you need $1.5 million. The Fidelity savings benchmark targets 10× your final salary by age 67. Individual targets vary based on retirement age, lifestyle costs, healthcare needs, and other income sources. Use the RetireStack Retirement Readiness Calculator for a personalized estimate.
What is the safe withdrawal rate for retirement?
The most widely cited safe withdrawal rate is 4% per year, established by William Bengen in 1994. Under this rule, a retiree with a $1,000,000 portfolio can withdraw $40,000 in year one, then adjust for inflation annually, with historically high (~95%) confidence the portfolio lasts 30 years. For longer retirements (35–40 years), researchers recommend 3.3%–3.5% to reduce sequence-of-returns risk.
