What is The Three-Bucket Retirement Withdrawal Strategy?
In retirement, how you withdraw your money matters as much as how much you've saved.
You've spent decades building wealth by contributing to 401(k)s and other investment accounts, and accumulating real estate or business equity. As you near retirement the question is not how else you can save, but: How do I withdraw money without running out, overpaying in taxes, or getting wiped out by a bad market?
For high-net-worth individuals, the lack of a plan can cost hundreds of thousands of dollars over retirement in taxes and missed growth.
The three-bucket strategy is a framework that helps avoid those problems.
What Is the Three-Bucket Strategy?
The three-bucket strategy divides your retirement savings into three "buckets," each to fund a different time horizon and have a different level of risk.
Bucket 1: Short-Term (Years 1–2)
Purpose: Cover short-term living expenses
Contents: Cash, money market funds, short-term CDs, high-yield savings
Risk level: Low
Goal: Stability
This is your liquidity reserve. It should serve as your “paycheck” in retirement, rather than an account you want to grow. It's meant to be available regardless of stock market performance.
Bucket 2: Medium-Term (Years 3–10)
Purpose: Refill Bucket 1 and provide moderate growth
Contents: Bonds, dividend-paying stocks, balanced funds, fixed income
Risk level: Moderate
Goal: Stability and growth
Bucket 2 will act as a bridge between your short-term cash and long-term investments. It will refill Bucket 1 for your retirement “paycheck” but should grow more than Bucket 1 originally did.
Bucket 3: Long-Term (Years 10+)
Purpose: Growth
Contents: Equities, growth-oriented investments, alternative assets
Risk level: Higher
Goal: Maximize long-term growth
Bucket 3’s risk level is higher because it is meant to sustain your portfolio over a 20 to 30 year retirement. Also, since it should last from year 10 onwards, the longer time horizon can give this bucket time to recover from any market downturns.
As you spend Bucket 1, you replenish it from Bucket 2. As Bucket 2 depletes, you refill it from Bucket 3. This keeps you liquid, and stops you from making panic-based decisions if markets drop, and keeps your long-term growth running.
How the Three Bucket Strategy Connects to the 4% Rule
We recently wrote about the 4% Rule of Retirement (read the article here), which says that you can withdraw 4% of your portfolio each year and have a high probability of not running out of money over a 30-year retirement.
The 4% rule tells you how much to withdraw, and the three-bucket strategy tells you where to withdraw from and in what order. Together, they give you a withdrawal rate and system.
For example, if your portfolio is $3M, the 4% rule suggests withdrawing $120k per year. The bucket strategy will make it so that Bucket 1 holds roughly $240k (2 years of that income), Bucket 2 holds the next few years and will be invested to (hopefully) grow modestly, and Bucket 3 holds the rest, invested for long-term growth.
As mentioned in our article, the 4% rule has some limitations for high net worth investors with complex portfolios. It was designed for a 30-year retirement with a traditional 60/40 portfolio. So, if you retire early, spend more in early retirement, or have concentrated asset positions, a lower withdrawal rate might be more appropriate. Your advisor should test your plan against multiple scenarios.
How The Three-Buckets Address Sequence of Returns Risk
One of the biggest threats to retirement is sequence of returns risk.
If the market drops significantly in the first few years of your retirement and you have to sell investments at low prices to cover living expenses, your portfolio may never fully recover.
Two retirees with identical portfolios and average returns can have very different outcomes depending on when the bad years hit.
The three-bucket strategy helps manage this risk.
Bucket 1 insulates you. You have 1-2 years of living expenses in cash to avoid needing to sell equities in a down market to pay your bills.
Bucket 2 provides a second layer of protection. Bonds and fixed income tend to hold value better (or even rise) when equities fall, so you have a source to draw from during multi-year downturns.
Bucket 3 stays invested. Because Buckets 1 and 2 cover shorter-term needs, your long-term investments have time to recover.
This allows your equity portfolio to behave like a long-term investor's portfolio.
Tax Planning Considerations: Where Most Retirees Leave Money on the Table
The three-bucket strategy is also a tax planning tool.
Different accounts are taxed differently:
Your withdrawal strategy should coordinate which buckets you draw from with your tax situation in that year. For example:
In a low-income year, drawing from your traditional IRA (while still staying in a lower tax bracket) is more efficient than waiting until RMDs force you into a higher bracket later.
In a high-income year, drawing from Roth or taxable accounts avoids piling more ordinary income on top of an already high tax bill.
Taxable accounts, when managed carefully, may fund spending while generating minimal taxable events. This is especially true if positions have a high cost basis.
The Roth Conversion Window
SECURE 2.0 pushed Required Minimum Distribution (RMD) age to 73. This creates a window between early 60s – 73 for early retirees, where your income may be lower since you stopped working but Social Security hasn’t kicked in yet. This gives you an opportunity for a Roth conversion.
In a Roth conversion you move money from your traditional IRA to a Roth IRA, pay the taxes on it now at a lower rate, and lock in future tax-free growth.
Roth assets grow tax-free, have no RMDs for the original account holder, and will pass to heirs income-tax-free (subject to the 10-year distribution rule under SECURE 2.0).
Inherited IRA Rules
Under SECURE 2.0, most non-spouse beneficiaries must now fully withdraw money from inherited IRAs within 10 years. In many cases, they have to take annual distributions throughout that period. For a high-earner inheriting a $2M IRA, this can mean significant forced income.
The right decisions will depend on your current marginal rate, your beneficiaries' likely tax situations, your charitable intentions, your estate size, and whether the current tax code favors action now.
Common Mistakes Retirees Make
Withdrawing from accounts in the wrong order
Many retirees spend taxable accounts first because "the IRA is for later." But this often leaves a large, fully-taxable IRA balance that generates large RMDs later. This might push you into higher brackets and triggering Medicare surcharges (IRMAA).Ignoring RMD timing until it's too late
A lack of RMD planning means missing the Roth conversion window.Treating all retirement income the same
Social Security, pension income, IRA withdrawals, Roth distributions, and capital gains are all taxed differently. Lumping them together leads to missed tax planning opportunities.Holding too much cash "to be safe"
Keeping years of expenses in cash can hurt your long-term returns. The three-bucket strategy provides mental comfort and an appropriate cash buffer.Not revisiting the plan
Markets, tax laws, and your spending change. A withdrawal strategy set at age 62 may not be right at 68 or 75. Annual reviews with your financial advisor and tax preparer keep the plan current.
The three-bucket strategy is more powerful when it's built and managed as part of a fully integrated financial and tax plan.
A coordinated team can:
Model Roth conversion scenarios in your actual projected tax picture, not estimates
Coordinate the timing of investment sales with your tax bracket in real time
Align your withdrawal sequence with estate goals and beneficiary designations
Test your plan against market downturns, longevity risk, and tax law changes
As always, we recommend working with a professional who understands both tax strategies and wealth management.

Q&As addressed in this article:
What is the three-bucket retirement strategy?
A framework for organizing retirement assets into three pools by time horizon: short-term (cash/liquidity), medium-term (bonds/balanced), and long-term (growth equities).How does the three-bucket strategy relate to the 4% rule?
The 4% rule establishes how much to withdraw annually, and the three-bucket strategy says where to withdraw from and in what order.What is sequence of returns risk?
The risk that a bad market in the early years of retirement (where you need to sell assets at depressed rates to fund cash needs) permanently damages your portfolio, even if/when markets later recover.When should I start Roth conversions?
The window between retirement and age 73 is ideal, especially if your income drops during that period.What do SECURE 2.0's inherited IRA rules mean for my estate plan?
Most non-spouse beneficiaries face a 10-year distribution window for inherited IRAs, which can cause your heirs to owe significant income taxes. Planning with Roth conversions, trusts, and charitable vehicles can reduce that burden.Do I need a financial advisor to implement the three-bucket strategy?
The framework is straightforward, but a professional can help address the tax layer of deciding which accounts to draw from, when, in what amounts, and how to coordinate that with Roth conversions, RMDs, and estate goals.
