The Bucket Strategy for Retirement Income: What Works and What Is Theater

Key takeaways

A bucket strategy holds one to three years of spending in cash, several more in bonds, and the rest in stocks, and refills the cash from the others.
Its real value is behavioral: a retiree who knows the next three years are covered does not sell stocks in a crash.
Mathematically it is a total-return portfolio with a cash allocation; the buckets add no return and can subtract some if the cash bucket is too large.
Held as one rebalanced allocation, a bucket portfolio and a plain portfolio end up in the same place; what matters is how much sits in bonds and whether withdrawals come from what is above target.

The bucket strategy is the most intuitive retirement income framework anyone has come up with, which is exactly why it gets sold so widely. Money for the next few years sits in cash. Money for the middle years sits in bonds. Money for the distant years sits in stocks. When markets fall, you spend from the cash and leave the stocks alone. It sounds like risk management, and part of it is. The rest is a way of drawing a picture of an ordinary balanced portfolio.

The standard version

Three buckets is the usual number.

Bucket one holds one to three years of spending, net of Social Security and pensions, in cash, money market funds, and short-term Treasuries. It earns little and never falls.

Bucket two holds the following five to seven years of spending in high-quality bonds or a bond ladder. It earns more than cash, wobbles a bit, and refills bucket one.

Bucket three is everything else, in stocks and other growth assets. It's expected to fall hard now and then and to grow the most over decades. It refills bucket two.

So a retiree spending $100,000 a year from the portfolio might hold $250,000 in bucket one, $600,000 in bucket two, and the remaining $1.15 million of a $2 million portfolio in bucket three. That's 12.5% cash, 30% bonds, and 57.5% stocks.

What actually works

The cash reserve. The one to three years of safe spending is the piece doing real work. It's the defense against sequence of returns risk. When stocks fall 30% in the first year of retirement, a retiree with three years of spending in cash sells nothing at the bottom, and the stocks get their time to recover. Every credible withdrawal strategy includes some version of this.

The behavioral effect. Knowing the next three years are funded, in a separate account with its own balance, makes it far easier to leave the stocks alone. Retirees who can see their spending money set aside are less likely to panic. This is the strongest argument for buckets, and we don't dismiss it as "merely psychological." Behavior is where most retirement plans fail.

The forced conversation about time. Assigning money to time horizons makes people think about when they'll actually need it. That's the right question.

What's theater

The idea that buckets add return. They don't. A three-bucket portfolio is a 57.5% stock, 30% bond, 12.5% cash allocation, and its expected return is the expected return of that allocation. Labeling the parts doesn't change the arithmetic. The same allocation held as a single rebalanced portfolio produces the same outcome, or slightly better, because it doesn't let cash drift.

The idea that bucket three is safe because it's long-term. Money is fungible. If buckets one and two run dry in a long bear market, bucket three gets sold at the bottom exactly like any other portfolio. Buckets don't eliminate sequence risk. They buy time, which is valuable and finite.

The oversized cash bucket. Presentations that recommend five years or more of cash produce a portfolio that's 25% or more in an asset earning less than inflation. Over a 30-year retirement that drag is large, and it's the price of a feeling. The evidence supports two to three years. Not five.

The vague refill rule. This is the part most bucket presentations skip. When and how does money move from stocks to bonds to cash? If bucket one gets refilled every year from bucket three regardless of markets, the strategy is just a total-return portfolio with a cash drag. If it's only refilled when stocks are up, that's a market-timing rule, and it needs a definition. Without a written refill rule, the buckets are a picture.

What we do instead

We skip the refill rule. We size the bond portion of the portfolio to cover several years of the spending the portfolio has to supply, net of Social Security and pensions, and then manage the whole thing as one rebalanced allocation. Each withdrawal comes from whatever is above its target, which in good years is stocks and in bad years is bonds, and new money goes to whatever is below. A long decline is handled by the rebalance and, if it runs long enough, by trimming discretionary spending per the guardrails. Research comparing the two approaches finds that a bucket strategy and a rebalanced portfolio holding the same allocation end up in the same place, so there is no reason to add bookkeeping that doesn't change the outcome.

Where buckets fit

For the right retiree, especially someone who spent a career watching balances and finds a market decline viscerally hard to sit through, showing how many years of spending the bonds cover is useful, and we do it. Underneath, though, it's a single allocation, managed across all accounts with asset location in mind (cash and bonds mostly in the IRA, stocks mostly in the taxable account and Roth), rebalanced by rule, with withdrawals sequenced for tax. The buckets are how we explain it. The rules are what make it work. That distinction sits at the heart of retirement income planning.

Frequently asked questions

How many years of cash should I hold?

In cash, two to three years of spending net of guaranteed income at most; more than that costs return without adding much safety. High-quality bonds do the same job with a better expected return, which is why we size the bond portion of the portfolio to the spending instead of holding a large cash bucket.

Should the buckets be separate accounts?

They can be, and for some people the separate statement is the whole point. Tax-wise it's better to hold the cash and bonds in the IRA and the stocks in taxable and Roth accounts, which means the buckets cross account lines. The mental model and the account structure don't have to match.

Is a bucket strategy the same as a bond ladder?

A bond ladder is one way to build bucket two: bonds maturing each year to fund that year's spending. It gives you certainty about the middle years. A bond fund does the same job with less precision and less effort; see bond ladder or bond fund.

Does the bucket approach work with the 4% rule?

Yes. The 4% rule sets the spending rate; buckets describe the allocation and the order of withdrawals. Different questions.
