Why Withdrawal Order Matters More Than Most People Think
Most retirees default to one of two approaches: either they withdraw proportionally from all accounts, or they draw from traditional accounts first because “they have to eventually.” Neither is always the cheaper one. Vanguard estimates that taking any required minimum distributions first, then spending taxable accounts before tax-advantaged ones, can add up to 1.2% a year on average compared with spending tax-advantaged accounts first (Putting a value on your value: Quantifying Vanguard Advisor's Alpha, July 2022). The gain is largest when taxable and tax-advantaged savings are about equal and the tax bracket is high, and it is zero when all savings are in one kind of account. That 1.2% is the top of Vanguard's range, over a 35-year horizon at a 40.8% marginal income tax rate. Morningstar measures it differently: as extra retirement income, which it expresses as the equivalent of about 0.23% a year for asset location and withdrawal order together (Blanchett and Kaplan, Alpha, Beta, and Now… Gamma, 2013).
The key insight is that you control your taxable income in retirement. Unlike during your working years (when your employer determines your salary), in retirement you choose how much income to recognize each year by selecting which account to draw from. This control lets you optimize your tax bracket utilization year by year.
The 4 Strategies Explained
Strategy 1: Naive (Proportional)
This baseline strategy withdraws from traditional, Roth, and taxable accounts in proportion to their current balances. If your portfolio is 50% traditional, 30% Roth, and 20% taxable, each withdrawal takes 50% from traditional, 30% from Roth, and 20% from taxable. This is the simplest approach and what many DIY retirees inadvertently use. It ignores tax implications entirely.
Strategy 2: Traditional-First
This strategy depletes your traditional (pre-tax) accounts first, then draws from taxable, then Roth last. The logic is to “get the taxes out of the way” while letting Roth accounts grow tax-free as long as possible. Front-loading traditional withdrawals can push early-retirement income into higher brackets, but it also shrinks the traditional balance before RMDs begin and before Social Security becomes taxable. For many spending levels it is the order with the lowest lifetime tax in this calculator; for others it is not.
Strategy 3: Roth-First
This strategy depletes Roth accounts first, preserving traditional accounts. This is usually the worst strategy because it wastes the tax-free compounding advantage of Roth accounts and forces larger RMDs later when traditional balances have grown unchecked. Roth-first only makes sense in narrow scenarios where you expect to be in a significantly lower tax bracket in late retirement.
Strategy 4: Bracket-Filling
This strategy fills the low tax brackets each year:
- Standard deduction zone (0% effective rate): Your first dollars of income are covered by the standard deduction ($16,100 single / $32,200 MFJ in 2026). Fill this with traditional withdrawals — it's effectively tax-free.
- 10% and 12% brackets: Continue filling with traditional withdrawals up to the top of the 12% bracket ($50,400 single / $100,800 MFJ in taxable income), counting the Social Security those withdrawals make taxable. While your benefits are being phased into tax, each extra dollar withdrawn can add up to $1.85 of taxable income, so the fill stops sooner than the bracket alone suggests.
- Remaining spending need: Once you've filled the low brackets, cover additional spending from Roth accounts (tax-free) or taxable accounts (potentially at 0% LTCG rates if your income is below the threshold).
- RMD compliance: From your RMD start age (73, or 75 if you were born in 1960 or later), mandatory traditional withdrawals are taken first, and the bracket-filling adjusts around them.
Which strategy is “Recommended”
The calculator first looks at how long each order's money lasts for the numbers you enter. Of the orders that last longest, it marks as Recommended the one with the lowest total lifetime tax, and shows how much less tax it pays than proportional withdrawals (strategy 1), or how much more. Recommended means the order whose money lasts longest. If more than one lasts as long, it is the one of those with the lowest total income tax over the years shown. It does not count tax still owed on traditional savings left at the end. If two orders last as long and pay exactly the same, the one listed first is marked. An order that pays less tax because its money runs out sooner, and so pays tax for fewer years, is not marked; the result names it.
Understanding RMD Integration
Required Minimum Distributions (RMDs) begin at age 73 if you were born from 1951 to 1959, or at 75 if you were born in 1960 or later, under the SECURE 2.0 Act (signed December 2022). For 2026, the IRS Uniform Lifetime Table specifies a divisor of 26.5 at age 73, meaning you must withdraw at least 1/26.5 = 3.77% of your traditional account balance. This divisor decreases each year (25.5 at 74, 24.6 at 75, etc.), forcing progressively larger withdrawals.
A critical planning opportunity: if your traditional balance is large, RMDs may exceed what you need for spending and push you into the 22% or 24% bracket. This is why many advisors recommend accelerated Roth conversions in the “gap years” between retirement and your RMD start age — converting just enough to fill the 12% bracket each year reduces the balance subject to RMDs later.
The 0% Long-Term Capital Gains Bracket
One of the most underutilized tax planning tools is the 0% long-term capital gains (LTCG) rate. In 2026, single filers with taxable income below $49,450 (or MFJ below $98,900) pay 0% federal tax on long-term capital gains. In a bracket-filling withdrawal strategy, years where your ordinary income is low (before Social Security starts, or in early retirement) are ideal for harvesting embedded gains in your taxable account at the 0% rate.
For example, if you have $200,000 in a taxable brokerage account with a $150,000 cost basis ($50,000 in unrealized gains), and your ordinary income in a given year is only $30,000, you could sell up to $19,450 in gains ($49,450 − $30,000) at 0% federal tax. This resets your cost basis higher, reducing future tax liability.
Social Security and Provisional Income
Social Security benefits are not always tax-free. Under IRC §86, the taxable portion depends on your “provisional income” (AGI + tax-exempt interest + 50% of SS benefits):
- Below $25,000 (single) / $32,000 (MFJ): 0% of SS is taxable
- $25,000-$34,000 (single) / $32,000-$44,000 (MFJ): Up to 50% of SS is taxable
- Above $34,000 (single) / $44,000 (MFJ): Up to 85% of SS is taxable
This creates a “tax torpedo” effect: traditional withdrawals increase your provisional income, which increases the taxable portion of Social Security, which further increases your taxable income. The effective marginal rate in this zone can exceed 40%. The bracket-filling strategy here counts this interaction when it fills the 12% bracket.
When to See a Financial Advisor
This calculator provides a strong starting framework, but several factors benefit from professional guidance:
- IRMAA planning: If your income triggers IRMAA surcharges on Medicare premiums ($109,000 single / $218,000 MFJ in 2026), an advisor can help sequence withdrawals to stay below the threshold.
- Roth conversion integration: Combining withdrawal sequencing with a multi-year Roth conversion ladder can compound tax savings significantly.
- State tax optimization: Some states exempt retirement income or Social Security from state tax — an advisor familiar with your state's rules can capture additional savings.
- Estate planning: If leaving a legacy is a priority, the best withdrawal order for you can change — Roth accounts are more valuable to heirs than traditional accounts because inherited Roth distributions are tax-free.
- Complex situations: Rental income, business income, large unrealized gains, charitable giving, or QCDs (Qualified Charitable Distributions) all affect which sequence costs least.
Frequently Asked Questions
What is withdrawal sequencing and why does it matter?
Withdrawal sequencing is the order in which you draw down your retirement accounts. The order determines how much tax you pay each year. Depending on your balances, income and spending, the lowest-tax order can pay tens of thousands of dollars less lifetime tax than proportional withdrawal, and which order that is varies: the calculator compares all four for your numbers. The difference compounds because money left in your portfolio continues to grow.
What are the 4 withdrawal strategies compared in this calculator?
(1) Naive/Proportional: withdraw from all accounts based on balance share. (2) Traditional-First: deplete pre-tax, then taxable, then Roth. (3) Roth-First: deplete Roth, then taxable, then traditional. (4) Bracket-Filling: fill low tax brackets with traditional, use Roth and taxable for the rest. Which order produces the lowest lifetime tax bill depends on your balances, income and spending, so the calculator compares all four for your numbers.
How does bracket-filling try to reduce retirement taxes?
By controlling which accounts you withdraw from each year, you keep your taxable income in the lowest possible brackets. Traditional withdrawals fill the 0% (standard deduction), 10%, and 12% brackets. Remaining spending comes from Roth (tax-free) or taxable (often at 0% LTCG). Whether that adds up to a lower lifetime tax than the other orders depends on your balances, income and spending; the calculator compares all four.
How do RMDs affect withdrawal sequencing?
Once they start (age 73, or 75 if you were born in 1960 or later), Required Minimum Distributions force a minimum traditional withdrawal based on the IRS Uniform Lifetime Table. If your traditional balance is large, RMDs may exceed the bracket-filling amount. Pre-retirement Roth conversions can reduce this risk by shrinking the traditional balance before RMDs begin.
When should I talk to a financial advisor about withdrawal sequencing?
When your combined portfolio exceeds $500,000, you have balances in all three account types, you are within 5 years of retirement, or you have complex tax situations. A fee-only fiduciary advisor can coordinate withdrawal sequencing with Roth conversions, IRMAA avoidance, Social Security timing, and estate planning.
