MarketWatch: 90% of Retirees Misjudge Withdrawal Order

What the Report Says

A MarketWatch report published on September 19, 2026 states that 90% of retirees are making a miscalculation with their savings. The specific error the report identifies is not about how much money a household has set aside or how those savings are invested. It is about the order in which that money is spent.

According to the report, the sequence in which a retiree draws down different pots of savings makes a difference for two things: their taxes and their enjoyment of life. The report frames the withdrawal order as a decision that carries consequences in both directions at once, affecting what a household owes the government and how much freedom it has to use its own money along the way.

The report does not present the miscalculation as a rare edge case. It puts the share of retirees making it at nine in ten, which is the central claim of the piece and the reason it is worth understanding even for households that have never thought of their savings as a set of accounts to be spent in a particular sequence.

Why the Order Matters at All

For most working Americans, saving happens in whatever order the paycheck allows. Money goes into an employer retirement plan, perhaps an individual retirement account, perhaps a regular taxable brokerage account, and perhaps a savings account. During the accumulation years, the tax treatment of each account is mostly a background detail. The contribution limits and any deduction or match are what get attention.

In retirement, the picture inverts. The money is no longer flowing in. It is flowing out, and each account type is taxed differently when it is tapped. Traditional retirement accounts, funded with pre-tax dollars, generally produce ordinary income when withdrawn. Roth accounts, funded with after-tax dollars, generally do not. Taxable brokerage accounts are subject to capital gains rules, which treat long-term gains differently from ordinary income and differently again from short-term gains. Cash savings generate interest that is taxed as ordinary income in the year it is earned.

Because those rules differ, the same total amount of spending can produce very different tax outcomes depending on which account the dollars come from in a given year. A retiree who pulls everything from a traditional account in a single year may push themselves into a higher bracket than they needed to occupy. A retiree who drains taxable accounts first may leave tax-deferred accounts to grow untouched for years, only to face required minimum distributions later that are larger than they would otherwise have been.

That is the mechanism behind the report's claim. The order is not a matter of bookkeeping preference. It changes the tax bill, and it changes how much of the portfolio remains available for later years.

The Second Half of the Claim

The MarketWatch report pairs taxes with enjoyment of life, which is the less familiar half of the argument. The two are connected, but not identical.

A withdrawal strategy that minimizes taxes on paper can still leave a retiree feeling constrained. If the plan requires spending only from accounts that carry a tax cost, or if it requires deferring spending to preserve a particular account, the household may be living more frugally than its actual resources require. Conversely, a retiree who spends freely from whichever account is convenient may be creating a larger tax liability than necessary, which reduces what is available later.

The report's framing suggests that the miscalculation is not simply an optimization problem to be solved for the lowest possible tax number. It is a question of matching the timing of spending to the timing of the tax treatment, so that the money is actually used rather than preserved for its own sake.

What It Affects for American Households

The practical reach of this issue is broad because it touches anyone who has saved across more than one type of account. That includes households with a workplace 401(k) or similar plan plus a brokerage account, households with both traditional and Roth individual retirement accounts, and households that hold cash reserves alongside invested assets.

It also interacts with Social Security. The tax treatment of Social Security benefits depends in part on a household's other income in a given year, which means the choice of which account to draw from can affect how much of the benefit is taxable. The report does not detail this interaction, but it is part of why the withdrawal sequence is not a standalone decision.

Medicare premiums are another area where income in a given year can matter, since some premium amounts are tied to reported income. A retiree who concentrates withdrawals in one year may affect costs in a later year without intending to.

For heirs, the order of withdrawals can also shape what is left behind and in what form. Different account types pass to beneficiaries under different rules, and the tax treatment for the recipient varies accordingly. A household that spends down one type of account first is effectively choosing which tax situation its beneficiaries will inherit.

What the Report Does Not Say

The report does not recommend a specific withdrawal order, and it does not provide a formula that applies to every household. The right sequence depends on a household's income sources, the size and mix of its accounts, its state of residence, its health and expected longevity, and its spending needs. Those factors vary too much for a single rule to fit everyone.

It also does not say that retirees are running out of money. The claim is about miscalculation, not depletion. A household can make the error the report describes and still be financially secure; it may simply be paying more tax than necessary or spending less freely than it could.

What the report does establish is that the sequencing decision exists, that it has consequences on both the tax side and the lifestyle side, and that by its account the large majority of retirees are not getting it right. For American readers, the takeaway is not a specific action but an awareness that the order in which savings are spent is a decision, whether or not it is made deliberately.
