Retirement Withdrawal Order Calculator

Frequently Asked Questions

Should I always withdraw from taxable accounts first?

Not necessarily. The classic order (taxable first, then traditional, then Roth) minimizes current taxes but can result in large RMDs later. A hybrid approach - filling lower brackets with traditional withdrawals or Roth conversions before 73 - often minimizes lifetime taxes even if it increases current-year taxes.

When should I start Roth conversions?

The best window is typically the years after retirement but before Social Security begins (often 62-69) when total income is relatively low. Converting just enough to fill the top of the 22% bracket each year can eliminate hundreds of thousands in future RMDs.

What is a qualified charitable distribution (QCD)?

A QCD is a direct transfer of up to $105,000 per year from an IRA to a qualified charity. It counts toward your RMD but is excluded from taxable income. It is the most tax-efficient way to give to charity in retirement, especially for those who cannot itemize deductions.

How do IRMAA cliffs affect withdrawal order decisions?

IRMAA adds Medicare surcharges at specific MAGI thresholds. A Roth conversion that pushes MAGI just above a threshold can cost $1,000-$5,000 more per year in Part B premiums. Plan Roth conversions to stay just below each IRMAA tier boundary.

How This Calculator Works

Most retirees hold three types of accounts, each with different tax treatment: taxable brokerage accounts (dividends and gains taxed annually; long-term gains at favorable rates), traditional pre-tax accounts (IRA, 401(k) - contributions were tax-deferred, all withdrawals taxed as ordinary income), and Roth accounts (contributions were after-tax, all qualified withdrawals permanently tax-free).

This calculator models a multi-year drawdown under a specified withdrawal order and tax bracket, projecting the end-of-year balance across all three buckets. It helps you visualize how quickly each bucket depletes and at what ages RMDs from the traditional bucket will be forced, so you can plan proactive conversions or distributions in low-income years before RMD age.

Classic Withdrawal Order

The traditional advice is to withdraw in this sequence:

Taxable accounts first: Use dividends, interest, and sell holdings. Long-term gains are taxed at 0%, 15%, or 20% - much lower than ordinary income for most retirees. Draws taxable down before death, where a step-up in basis would otherwise eliminate the unrealized gain tax anyway.

Traditional pre-tax accounts second: Defer as long as possible to keep tax-deferred growth, but do not ignore this bucket entirely before age 73 or RMDs become large and unmanageable.

Roth accounts last: No RMDs, tax-free growth, optimal for late retirement and legacy. Leaving Roth untouched as long as possible maximizes its compounding benefit.

This order minimizes immediate tax drag but may not minimize lifetime taxes if traditional balances grow so large that RMDs push you into high brackets at 73+.

Modern Refinement: Bracket Filling

A more sophisticated approach uses the years between retirement and age 73 to "fill up" lower tax brackets with traditional withdrawals or Roth conversions. The goal: empty enough of the traditional bucket in low-income years to prevent future RMDs from stacking on top of other income and pushing into higher brackets.

Example: A couple retires at 62 with $1M in a traditional IRA and $500K in Roth. Social Security starts at 70. From 62-69, they have relatively low taxable income. Using that window to convert $50,000-$80,000/year from traditional to Roth reduces the RMD burden at 73 and may save tens of thousands in lifetime taxes, even though Roth conversions increase current-year taxes.

The optimal bracket-filling amount is usually up to the top of the 22% or 24% bracket - above which the IRMAA cliff and other phase-outs can create effective marginal rates much higher than the stated rate.

RMD Interaction with Withdrawal Order

Once RMDs begin at 73, you lose control over the traditional bucket - the IRS mandates a minimum withdrawal each year regardless of your other income. If the traditional balance has grown very large, RMDs alone may push you into the 22%, 24%, or even 32% bracket, with Medicare IRMAA surcharges layered on top.

The best time to address this is before 73. Using retirement years between 62 and 72 to systematically take additional traditional distributions or do Roth conversions - keeping total income just below IRMAA tier boundaries - reshapes the RMD trajectory significantly. A financial planning software tool that models this year-by-year with your actual balances and tax situation is worth the cost for retirees with large traditional balances.

Tips and Common Mistakes

Do not ignore the traditional bucket before 73: Early strategic withdrawals in low-income years almost always beat the RMD avalanche later.

Coordinate with Social Security timing: The years before SS begins are typically the best window for Roth conversions because total income is lowest.

Watch for IRMAA cliffs: Roth conversions that push MAGI above an IRMAA tier threshold add a hidden Medicare surcharge. Plan to stay just below the nearest cliff.

Qualified Charitable Distributions (QCDs): If you are over 70½ and charitably inclined, directing IRA money directly to charity (up to $105,000/year) satisfies RMDs without adding to taxable income - the most tax-efficient charitable giving tool available.

Tax laws change frequently. Verify current limits at IRS.gov and consult a qualified financial advisor before making retirement decisions.
