The bucket strategy: dividing your money by when you'll spend it

Every strategy so far has treated your money as one pool and argued about what percentage to skim off it. The bucket strategy throws that framing out. It says: don’t hold one portfolio, hold three, sorted by when you’ll spend the money — and suddenly the whole sequence-risk problem looks different. This is the seventh stop on our withdrawal tour, and it’s the most intuitive strategy of the lot, which is exactly why it’s so popular and why it deserves a clear-eyed look at what it does and doesn’t actually achieve.

The structure

The approach was pioneered by the wealth manager Harold Evensky, who started with a simple “money for now versus money for later” split and later refined it into three buckets:

Bucket one — cash, for now. One to two years (some go up to five) of living expenses, held in cash and cash-like instruments. This is what you actually spend from. It doesn’t earn much, and that’s fine — its job isn’t return, it’s not falling.

Bucket two — bonds, for soon. The next several years of expenses, held in high-quality bonds and other conservative, medium-term assets. This is the reservoir that refills bucket one. More return than cash, more stability than stocks.

Bucket three — stocks, for later. Everything else, invested for long-term growth in equities. You won’t touch this for a decade or more, so it can be as volatile as it likes. Its job is to grow, and to eventually top up the calmer buckets.

You live out of bucket one. Periodically — as it drains — you refill it from bucket two, and refill bucket two from bucket three’s growth. Money flows down the buckets from risky-and-distant to safe-and-imminent as time passes.

Why it works against sequence risk

The bucket strategy’s whole reason for existing is sequence-of-returns risk, and its defence against it is beautifully concrete. The thing that destroys an early retirement is being forced to sell stocks at the bottom to fund your spending. The bucket structure means you’re never forced to — because when a crash hits, you’re spending from bucket one, which is cash, entirely untouched by the falling market. Your equities can crater 40% and it changes nothing about how you eat this month, because this month’s money was sitting in cash the whole time.

That buys the one thing sequence risk demands: time for the stocks to recover before you have to sell them. You simply don’t refill from bucket three while it’s down; you live off cash and bonds and wait. By the time you’re forced to sell equities, the theory goes, they’ve had years to bounce back. You’ve broken the fatal link between “market falls” and “I must sell shares.”

The uncomfortable question underneath

Now the part the enthusiasts skip. Academically, the bucket strategy is more contested than its popularity suggests, and it’s worth understanding why before you commit to it.

The critique goes like this: strip away the three labelled accounts and ask what you actually hold, and it’s just an asset allocation — some cash, some bonds, some stocks — in some overall proportion. A retiree with a single portfolio at, say, 60% stocks / 40% bonds-and-cash, rebalanced sensibly, ends up holding almost the same mix and can behave almost identically in a downturn (spend the safe assets, leave the stocks to recover). So is the bucket strategy a genuinely different strategy, or the same allocation wearing a more comforting story? Several researchers argue it’s largely the latter — that the buckets are a behavioural device more than a mathematical edge, and that a naively-run bucket approach can even drift to an overall allocation that’s more conservative (and lower-returning) than the retiree intended, as the cash bucket sits there earning nothing for years.

Here’s the fair conclusion: that behavioural benefit is real and not to be sneered at. The reason retirees blow up isn’t usually bad maths — it’s panic-selling stocks in a crash. If mentally ring-fencing “two years of spending, safe, right here” is what lets you hold your nerve and leave your equities alone through a bear market, then the strategy has done its most important job, whatever the equations say. A plan you can emotionally stick to beats an optimal plan you abandon at the worst moment.

Strengths and weaknesses

The strengths: it’s wonderfully intuitive — anyone can grasp “spend the cash, refill from bonds, let the stocks grow” — and that intuitiveness translates directly into the calm that prevents catastrophic behaviour. It gives you a concrete, non-scary answer to “what do I do in a crash?”: nothing, you spend bucket one.

The weaknesses: the cash bucket is a real drag on returns — money parked earning little for years has an opportunity cost, and over a long retirement that cost compounds. The refill rules are fuzzy (when exactly do you top up bucket one, and from which bucket, in what market?) and different people implement them very differently, with real consequences. And, as above, it may not actually outperform a simple, well-rebalanced allocation — you might be paying for peace of mind rather than performance. That can be a fair trade, but you should know that’s the trade you’re making.

Who it suits, and how Strata helps

The bucket strategy suits the retiree whose biggest risk is themselves — who knows they’d be tempted to sell in a panic and wants a structure that talks them out of it. It suits people who think in concrete terms rather than percentages, and who sleep better seeing “here is exactly where the next two years of spending lives.”

Strata fits this approach naturally, because buckets are really about seeing your money organised by account and asset type. You can hold your cash reserve, your bond holdings, and your growth portfolio in separate accounts tracked together — and because Strata gives you one reconciled view across all of them, you can watch bucket one draining and know exactly when it’s time to refill, without logging into four different places to work out where you stand. The strategy lives or dies on knowing your balances at a glance, and that’s precisely what a single reconciled ledger is for.

Next we take the “safe money for near-term spending” idea to its logical, precise extreme — building a ladder of bonds that matures exactly when you need each year’s cash: bond and TIPS ladders. Or build your portfolio and set your buckets up as accounts you can actually watch.
