Retirement Bucket Strategy: How 3 Buckets Work, Refill, and Fail

Say an investment trades for $100 a share. Selling 400 shares raises $40,000 before taxes and costs. If the price falls 30% to $70, raising at least $40,000 takes 572 whole shares. That’s 43% more shares for the same cash need. Those extra shares won’t be there when the investment eventually recovers.

This is sequence-of-returns risk: the order in which investment gains and losses arrive matters when withdrawals are taking money out of the portfolio. Two retirees can experience similar long-run average investment returns but very different retirement outcomes if one faces steep losses early while withdrawing.

The useful question is: What pays the bills while I wait? That is the job of a withdrawal policy, whether or not you use buckets.

During one conversation, the possibility of an economic downturn came up. I made the case that established consumer companies might still have customers years later. Would people simply stop brushing their teeth with Crest?

Mrs. Nelson had a better objection than I expected. People might keep brushing their teeth, she reasoned, but shop at Dollar Tree instead.

Good point. I stopped at Dollar Tree on my way home and looked. There was a tube of Crest. I photographed it and sent her the picture. Her objection made me test an assumption instead of waving it away.

Both observations could be true. People might change where they buy a product and still buy the brand. But a recognizable brand on a shelf does not mean its parent company’s stock price cannot fall, or that a retiree can comfortably wait through that fall.

The lesson was about the household, not Crest. You can believe a business will survive a downturn and still need an entirely different answer for next year’s bills. That answer might involve lifetime income, cash, bonds, flexible withdrawals—or a mix.

Confidence in an investment is not the same thing as a plan for spending it.

For the broader investment mix behind the buckets, see Asset Allocation for Retirees: Stocks, Bonds & Cash. The bucket plan decides when investments may fund spending; asset allocation decides how much risk the overall portfolio takes.

Bucket 1: Money you’ll need soon

This is the spending reserve. In a common version, it covers roughly one or two years of planned portfolio withdrawals, plus any additional near-term outlay that isn’t already accounted for. It might hold insured deposits, Treasury bills or another appropriate short-term cash equivalent. Its job is access and relative stability, not chasing the highest return.

Bucket 2: The intermediate runway

This money is intended to help fund later spending and replenish Bucket 1. High-quality bonds or a thoughtfully designed maturity ladder can serve this job. Interest payments and maturing principal can flow toward near-term withdrawals. But a bond fund’s value can fall, individual bonds can have credit risk, and higher yields don’t automatically mean more dependable spending power.

Bucket 3: Money that gets time to grow

This holds investments intended for longer-term growth, usually diversified stocks and other assets appropriate to the household’s risk capacity. The hope is that you won’t need to liquidate these holdings to pay ordinary bills immediately after a severe decline. That is why its refill rule matters.

Morningstar’s bucket allocation guide likewise starts with actual portfolio spending needs and then works backward to stocks, bonds and cash. The key is to avoid confusing a household’s total expenses with the amount its portfolio must provide.

• Bucket 1: $250,000 in near-term spending reserves.
• Bucket 2: $750,000 in intermediate-term income and stability investments.
• Bucket 3: $2,000,000 in long-term growth assets.
• Portfolio-funded spending need: $125,000 a year, after other household income, before future inflation or any unmodeled taxes and fees.

With zero investment earnings, $1 million in the first two buckets would cover $125,000 per year for eight years only if those assets remain available at their assumed values when needed. That is a cash-flow illustration, not a guarantee of eight years’ protection: bond prices can change, maturities may not line up, and spending and taxes can increase.

Now suppose Bucket 2 produces $40,000 a year in cash distributions and those amounts really are earnings rather than a return of principal. That’s approximately 5.33% of its starting $750,000 value—a hypothetical assumption, not a promised yield or a safe income target.

By the end of year two, the household has spent $250,000 but has also received $80,000 of distributions. Bucket 1 still holds $80,000, which would cover approximately 7.7 more months at the original $125,000 annual withdrawal pace if no new cash arrived.

The practical point: you can route cash flows toward spending before Bucket 1 runs dry.

One important accounting rule: if those $40,000 payments partly represent the return of your own principal, don’t count them as both earnings and an intact Bucket 2 balance. The portfolio didn’t create money merely by moving it from one account to another.

And the $125,000 spending need is an assumption, not a declaration that a $3 million portfolio can safely sustain that amount forever. Starting withdrawals are about 4.17% of the full portfolio; sustainability still depends on return paths, inflation, taxes, longevity and spending flexibility. See my retirement money longevity calculator for the separate sustainability question.

Illustration: The retirement bucket strategy organizes a portfolio around cash for near-term withdrawals, intermediate income assets, and longer-term growth. The year ranges are examples, not fixed rules.

A useful maintenance plan should answer four questions before the first serious decline:

1. What funds the monthly withdrawal? Usually cash already earmarked for spending, supplemented by relevant income distributions and maturities. Decide which accounts will actually make the payments.
2. When does Bucket 1 need a refill? Set a review date and a minimum reserve range tied to the next known withdrawals—not a guess about when stocks have peaked.
3. What should be sold or allowed to mature? Consider the overall target allocation, assets that are overweight, cash flows already scheduled, trading costs and taxes. In a strong stock year, trimming appreciated equities may replenish the reserve. In a weak year, cash and suitable bond maturities may help instead.
4. What happens when nothing looks attractive to sell? Review spending flexibility, available safe maturities, risk exposures and whether the long-term plan needs a controlled adjustment. Don’t assume you can avoid selling risky assets indefinitely.

Suppose Bucket 3 rises from $2 million to $2.2 million. That $200,000 gain is not an automatic $200,000 refill. Sell only what makes sense after checking the overall allocation, cash target, taxes and coming withdrawals.

One illustrative refill sequence (not a universal selling order): At a scheduled review, first account for cash already available from interest, dividends and bond maturities. Next, if cash is below its target range, consider selling assets that are overweight relative to your overall allocation, after checking taxes and account constraints. If markets are down and no sale is attractive, use the reserve as intended while reviewing spending and the timing of remaining maturities. Set a floor that triggers a fresh plan review; do not promise to avoid stock sales indefinitely.

In practice, withdrawals can become part of disciplined rebalancing: sell assets that are overweight relative to the plan, rather than making a market forecast. The SEC’s investor education guide explains rebalancing as the process of bringing a portfolio back to its target allocation. It also warns that cash’s apparent safety comes with inflation risk.

Do not make the next refill depend on guessing the market top.

Long stretches of disappointing returns have happened, and outcomes depend on whether you measure price changes, dividends, inflation or the exact start and end dates. Historical returns are not a promise of recovery within ten years.

The 2000–2009 period is a reminder that U.S. large-cap stocks can deliver poor cumulative returns across a full decade, depending on the exact measure. Even when a portfolio eventually grows again, a retiree who has been withdrawing through the bad years may have fewer shares left to benefit.

A long reserve can help. It isn’t an excuse to call Bucket 2 risk-free. In 2022, stocks and many bonds fell together as interest rates rose. The SEC’s guidance on bond funds explains that rising rates can reduce bond-fund prices and that credit quality and maturity still matter.

Your plan therefore needs to withstand more than the slogan, Stocks fall, bonds go up. Sometimes they don’t. A well-matched maturity ladder, sufficient liquidity and flexible withdrawals may be more useful than counting on a bond fund’s market price to rescue the stock allocation.

If that couple knows they’ll replace a car for $45,000 next year and hasn’t already included the purchase in the annual budget, they may want to account for it separately. But if the car was already included in the $140,000 spending figure, don’t count it twice.

The more dependable outside income covers essential spending, the less exposed a retiree may be to forced portfolio withdrawals. Still, cash has a cost: over decades inflation can erode its buying power, and substantial cash holdings can reduce expected long-term returns.

For a household with a strong pension and low portfolio withdrawals, an enormous cash bucket might be unnecessary. For someone living almost entirely on investments, especially just after retirement, near-term liquidity may deserve more attention. For both, the right answer should include a plan for when cash gets depleted.

Morningstar research first published in 2024 and updated in 2025 compared systematic withdrawals with several bucket approaches. Its modeled cash-reserve and two three-bucket variants underperformed systematic withdrawals on viable spending, while a different time-bucket method delivered higher modeled spending with a wider spread of outcomes. These are results for specific rules and assumptions, not a verdict on every possible bucket plan.

Here is the twist: when Morningstar modeled an investor abandoning equities after a sharp loss, systematic withdrawals performed worse than the cash-reserve and three-bucket strategies. The point is not that buckets beat rebalancing. It is that the plan someone can follow may beat a theoretically sound plan they abandon at the worst moment.

A simple target allocation with periodic rebalancing can achieve many of the same portfolio-management tasks with fewer rules and fewer opportunities for confusion. That’s a legitimate criticism, especially if someone treats each bucket as an isolated account and never checks the combined portfolio.

That matches what I saw in planning conversations: buckets sometimes helped people stick to a plan because they could identify next year’s spending money. It does not prove a performance advantage for the portfolio itself.

If the buckets make the household more disciplined and the rules are sound, they can be useful. If they become an elaborate excuse for market timing or excessive cash, simplify them.

If the retirement date, income floor, and withdrawal amount are not decided yet, start with my five decisions for planning retirement before assigning money to three buckets.

Two people might have been married 30, 40 or 50 years. Same house. Same accounts. Same money. But one sees a 25% stock decline as a temporary setback; the other sees a threat to the rest of their life. One wants to leave as much as possible to children. The other doesn’t want to spend retirement denying themselves experiences they saved for.

There isn’t necessarily a villain in that conversation. They are weighting different risks. A rigid rule of thumb may produce a neat answer on paper and a terrible argument at the kitchen table.

The better question is: What part of the household’s spending has to be dependable, and how much uncertainty can both people actually live with? The answer can guide cash, bonds, growth assets, spending flexibility and whether any additional lifetime income is worth considering.

For readers who need to separate their willingness to accept risk from their financial ability to absorb it, I explain that distinction in Risk Tolerance in Investing.

Your priorities can change. Your withdrawal rules should be reviewable without becoming a reaction to every market headline.

That doesn’t mean changing investments every time a headline scares you. It means setting review triggers beyond the stock market: a death, major health change, new dependent, large inheritance, an unexpected expense, a material shift in guaranteed income, or simply a change in your willingness to manage complicated rules.

Ask whether your 85-year-old self—or a surviving spouse—could operate the system without memorizing trading rules. If not, simplify it now.

A sustainable plan should be something the surviving spouse can understand without an hour-long lecture about which ETF to sell on a Wednesday.

Some lifetime-income arrangements can reduce the amount a household must withdraw from a volatile portfolio to pay necessary bills. But the details matter. Purchasing an annuity may involve giving up liquidity, accepting less inflation protection, choosing a survivor benefit that affects the payment, and relying on the issuing insurer’s financial strength. The SEC’s annuity guide outlines the contract differences and risks. My immediate annuity guide explores the specific tradeoffs.

I would not classify the entire value of a lifetime-income contract as readily spendable Bucket 2 money. A monthly annuity payment and a liquid bond holding do different jobs. Count income as income, and count liquid assets as liquid assets.

Some retirees value a reliable floor for essentials; others prioritize flexibility, inheritance or continued market exposure. The right mix depends on the household, the contracts and what could change later.

• Annual spending need: What does the household actually expect to spend, including irregular bills?
• Dependable outside income: What portion is covered by Social Security, pensions or other payments, and which benefits continue for a survivor?
• Annual portfolio gap: How much must investments provide after the dependable income is counted?
• Available near-term money: What can be spent or allowed to mature without depending on stock prices recovering next year?
• Refill and change rules: Who decides what to sell, when is the reserve reviewed, and what life changes would require a new plan?

Then ask both spouses to answer one more question separately: If the market fell 30% tomorrow, what would make you feel that this plan was still working? Compare answers before choosing investments. The disagreement could tell you more than a risk-tolerance quiz.

The test is not whether you can draw three buckets. It is whether the withdrawal plan still makes sense when markets fall, life changes—or one spouse has to manage it alone.
