The 4% rule (and its critics)

The 4% rule comes from the Trinity Study and Bill Bengen's work in the 1990s: a retiree could withdraw 4% of the starting portfolio in year one, adjust that dollar amount for inflation each year, and have a high probability of the portfolio lasting 30 years.

Newer research pushes back. Morningstar's 2021 research suggested that elevated valuations and lower expected bond returns make 3.3% a safer starting number. 4% is not a guarantee. It is a starting point that failed in roughly 5% of historical 30-year scenarios.

Withdrawal sequencing

The textbook sequence is taxable first, then traditional, then Roth - under the theory that this lets tax-advantaged accounts grow longest. That is often wrong. It ignores tax-bracket management.

A smarter approach: each year, figure out how much you can pull from the traditional IRAIndividual Retirement Account (IRA)A retirement account with tax advantages and eligibility rules. Traditional IRA contributions may be deductible; taxable withdrawals generally enter income.

Fill that bucket first - even if you do not need the cash - and reinvest the excess. This drains the pre-tax account at low rates before RMDs force you into higher brackets.

1. Fill the 12% bracket from traditional 401(k)/IRA every year.
2. Fund your living expenses from a mix of taxable (high-cost-basis lots first) and traditional as needed.
3. Leave the Roth IRA for last. It passes to heirs tax-free and is never subject to RMDs during your lifetime.

RMDs

Required Minimum Distributions force you to withdraw a percentage of traditional retirement accounts every year starting at age 73. The age rises to 75 for those born in 1960 or later. The penalty for missing an RMD used to be 50%; it is now 25%, and can be reduced further for timely correction.

Roth conversions earlier - between retirement and RMD age (73 or 75) - are the main tool to shrink this future tax bill.

Healthcare costs

Fidelity's annual estimate puts total retirement healthcare costs for a 65-year-old couple at roughly $371,000. Medicare covers a lot - but nowhere close to everything.

Gaps most retirees underestimate:

• Dental and vision - mostly not covered by traditional Medicare.
• Hearing aids - typically $2,000+ per ear, little Medicare coverage.
• Long-term care - Medicare covers only short stays. Memory care or assisted living can run $6,000 to $10,000+ per month.
• Out-of-pocket for non-formulary prescriptions and specialty drugs.

Long-term care insurance is expensive and sometimes worth it. Self-insuring with a dedicated bucket of the portfolio is the alternative most well-funded retirees choose.

Bitcoin in retirement

If you accumulated meaningful Bitcoin before retirement, you face a choice: hold it as a generational asset, or gradually convert it to an income stream.

Both are valid. The right choice depends on your heirs' situation, your tax position, and how much spending flexibility you have. See Exit Strategy and Inheritance.
