The Retirement Bucket Strategy: How to Set It Up and Refill It

The first bad market of your retirement will test you more than any bear market during your working years. When you were saving, a 25% drop was a buying opportunity. When you are withdrawing, it is a threat, because every dollar you sell at a low price is a dollar that cannot recover. The retirement bucket strategy exists to solve that specific problem: it keeps the money you will spend soon in assets that do not fall, so you can leave the rest invested through the storm.

The idea is simple, and it is popular because it is intuitive. But there is real craft in sizing the buckets, deciding what goes in each, and, most of all, setting rules for how the buckets get refilled. A bucket plan without refill rules is just a pile of cash that slowly runs out while your stock allocation drifts upward.

This guide covers how the strategy works, how to build it from your own numbers, the refilling rules that make it durable, where it fits alongside other withdrawal approaches, and the mistakes we see when people set one up on their own. It is educational rather than individualized advice, and our retirement planning team builds these structures as part of a full income plan.

How the Retirement Bucket Strategy Works

Instead of viewing your portfolio as one pool with a single allocation, you sort it into three (sometimes four) buckets based on when the money will be spent. Each bucket holds investments appropriate to its time horizon.

Bucket one: cash for the next one to two years

This bucket holds the spending your portfolio must cover for the next 12 to 24 months, in cash and cash equivalents: a high-yield savings account, a money market fund, Treasury bills, or short CDs. It earns a modest yield and does not fluctuate. Its purpose is to pay your bills without selling anything else, no matter what markets do.

Bucket two: income and stability for years three through ten

This bucket holds roughly the next seven to eight years of spending in high-quality bonds, bond ladders, Treasury notes, TIPS, and other assets that produce income and rarely lose much value. A bond ladder with a rung maturing each year is a natural fit, because each maturity can move into bucket one on schedule. Some retirees include an income annuity here for a portion of core expenses.

Bucket three: growth for year eleven and beyond

Everything else goes into a diversified stock portfolio, along with any other long-horizon assets. This bucket has a decade or more before it is needed, which is long enough to ride through most bear markets and recover. It is the engine that keeps the plan ahead of inflation over a 30-year retirement.

Why It Works: Sequence of Returns Risk

Two retirees can earn the same average return over 30 years and end up in completely different places depending on the order in which the returns arrive. A retiree who suffers a 30% decline in year one, while withdrawing 4% a year, may never recover, because the withdrawals are taken from a shrunken base. A retiree who gets the same decline in year 20 barely notices. This is sequence of returns risk, and it is concentrated in the five years before and the ten years after retirement.

The bucket strategy addresses it directly. With two years of cash and eight years of bonds, you can go a full decade without selling a single share of stock. Most bear markets have recovered well within that window, though nothing guarantees the next one will. The structure also helps behaviorally, which is not a small thing: retirees who know their next eight years of spending are secure are far less likely to sell everything at the bottom. Our article on sequence of returns risk shows the math in detail.

There is a cost. Holding two years of cash and eight of bonds means a meaningful share of the portfolio earns lower expected returns than stocks. For a retiree spending 4% a year, the buckets imply roughly 40% in cash and bonds, which is a conventional allocation for that stage. For a retiree spending 2% a year, the buckets imply only 20% in cash and bonds, and the growth bucket carries more of the load.

How to Size Each Bucket

The sizing starts with one number: your annual spending gap.

Step one: calculate the gap

Add up expected annual spending, including taxes and healthcare. Subtract reliable income: Social Security, pensions, annuity payments, rental income. What remains is the amount your portfolio must supply each year. A couple spending $180,000 with $70,000 in Social Security and pension income has a $110,000 gap. Our retirement readiness calculator can help you frame the inputs.

Step two: fill the buckets from the gap

With a $110,000 gap, bucket one holds $110,000 to $220,000 in cash. Bucket two holds about $880,000 in bonds and stable income assets (eight years). Bucket three holds everything else. On a $3,000,000 portfolio, that is roughly 5% cash, 30% bonds, and 65% stocks. On a $2,000,000 portfolio, it is closer to 8%, 44%, and 48%, which is a reasonable signal that the plan is tighter and the growth bucket has less room for error.

Step three: adjust for what changes

Spending gaps are rarely constant. A couple retiring at 62 may have a large gap until Social Security starts at 70, then a much smaller one. Buckets one and two should be sized for the larger early gap, and the plan should note when they can shrink. Large one-time expenses, such as a roof, a wedding, or a car, belong in bucket one or two as separate line items rather than as surprises drawn from stocks.

Refilling the Buckets

Refilling is the part most articles skip and the part that determines whether the strategy survives contact with a real bear market. There are two broad approaches, and you should choose one in advance.

Calendar refilling

Once a year, sell enough from bucket three to top bucket one back to its target, and move a maturing bond rung from bucket two into bucket one. This is simple and disciplined, but it means selling stocks every year, including in down years. It works best when paired with a rebalancing view: if stocks have fallen, you sell bonds to refill cash instead, and if stocks have risen, you sell stocks.

Threshold refilling

Refill bucket one from bucket three only when stocks are above a reference level, such as their value at the start of the year or a trailing high. When stocks are down, let bucket one drain and pull from bucket two. This is the approach that most fully protects against selling low, but it needs explicit rules: what counts as down, how far bucket one can fall before you refill from bonds regardless, and when a long bull market means you should skim gains into cash even if the cash bucket is full.

A simple rule set

A workable framework many retirees can follow:

• Each January, if stocks ended the prior year up, sell stocks to refill bucket one to 24 months of spending gap and rebalance bucket three.
• If stocks ended the year down, do not sell stocks. Refill bucket one from the maturing bond rung and, if needed, from bucket two.
• If bucket one falls below 12 months and stocks are still down, refill from bucket two to 18 months and stop there.
• If bucket two falls below five years of spending, resume refilling it from stocks in the next up year, prioritizing it over bucket one.
• Review the whole structure every year and after any major life change.

What Goes in Each Bucket and Where

Buckets are about timing, but taxes are about account type, and the two have to be reconciled. Bucket one cash can live in a taxable account for accessibility, but if most of your money is in an IRA, part of the cash bucket may sit inside the IRA and be distributed on a schedule. Bucket two bonds are usually tax-efficient inside an IRA, where their interest is deferred. Bucket three stocks fit well in Roth and taxable accounts, where growth is tax-free or taxed at capital gains rates.

This means a bucket may be spread across several accounts. That is fine. Track the buckets on a simple spreadsheet, not by account, and let the withdrawal plan determine which account actually funds each year's spending. Our article on retirement withdrawal order explains how to coordinate the account sequencing with the bucket structure and with Medicare and Social Security thresholds.

For the bond bucket, investor.gov's overview of bonds and fixed income is a useful primer, and TreasuryDirect explains how to ladder Treasuries directly.

Bucket Strategy vs Other Withdrawal Approaches

A total-return approach with periodic rebalancing produces similar results in most simulations; the buckets are, in effect, a rebalancing discipline with a story attached. A dynamic withdrawal approach, where spending adjusts up or down based on portfolio performance, addresses the same risk from the spending side rather than the asset side. Guardrail methods set a withdrawal rate with triggers to cut spending after bad years and raise it after good ones.

These are not mutually exclusive. Many of the strongest plans use buckets for structure, a total-return view for the underlying allocation, and modest spending guardrails for resilience. What matters is that the retiree understands the plan well enough to follow it in a bad year, which is where the bucket framing earns its place. Consumer-facing guidance from the CFPB on planning for retirement covers the broader decision set.

Common Mistakes

The failures we see share a few patterns.

• Oversizing bucket one. Five years of cash feels safe but costs real return over a long retirement. One to two years is the norm.
• No refill rules. The cash bucket drains, the stock bucket grows, and the portfolio becomes more aggressive precisely when the retiree is older.
• Treating each bucket as a separate account with its own allocation, which creates duplicate positions and makes rebalancing harder.
• Ignoring taxes when refilling, such as selling appreciated stock in a taxable account in a year when an IRA withdrawal would have been cheaper.
• Forgetting that bucket two bonds can lose value when rates rise. A ladder held to maturity avoids the issue; a bond fund does not.
• Building the buckets once and never revisiting them as spending, income sources, and health change.

The retirement bucket strategy is a way to make sure the money you need soon is never at the mercy of the market, while the money you need later keeps growing. Size the buckets from your real spending gap, put the right assets in the right accounts, and write down the refill rules before the first bad year arrives.
