Why plan withdrawals before retirement?

A withdrawal plan turns a pile of savings into dependable income. It forces you to (1) quantify your spending needs, (2) identify income sources, (3) test tax and sequence-of-return risks, and (4) set withdrawal rules that adapt over time. Planning ahead reduces stress and improves outcomes: retirees who model withdrawals are less likely to deplete assets prematurely or pay avoidable taxes (EBRI; CFPB).

Step-by-step process to model retirement income

  1. Project spending, not savings targets
  • Build a realistic retirement budget: essentials (housing, food, healthcare), discretionary (travel, hobbies), and one-time events (home repairs, gifts). Use 12 months of actual spending as a baseline, then adjust for retirement changes (e.g., mortgage paid off, lower commuting costs, higher health costs).
  • In my practice, clients who itemize projected annual costs see clearer trade-offs—cutting $6k/year in discretionary spending can reduce required portfolio withdrawals by the same amount and materially improve longevity of assets.
  1. Inventory every income source
  • List Social Security, pensions, annuities, rental income, expected part-time work, and balances inside IRAs, 401(k)s, Roth accounts, and taxable brokerage accounts. Include projected start dates and index benefits for inflation where applicable (Social Security benefit statements show your estimated benefit at different claiming ages; SSA.gov).
  1. Decide on a withdrawal architecture
  • Buckets vs. blended approach: choose a structure that matches your risk tolerance and liquidity needs. A popular method is a short-term cash/bond bucket for 3–7 years of spending, a growth bucket (stocks) for long-term inflation protection, and a tax bucket strategy for sequencing withdrawals. See our explainer on the buckets vs. blended approach here: “Buckets vs Blended Approach: Creating a Retirement Withdrawal Plan” (https://finhelp.io/glossary/buckets-vs-blended-approach-creating-a-retirement-withdrawal-plan/).
  1. Pick a withdrawal guideline and stress-test it
  • Common rules: fixed-percentage (e.g., 4% rule), fixed-dollar with inflation adjustments, dynamic rules tied to portfolio performance, or required minimum distributions (RMD)-aware methods.
  • The 4% rule is a simple starting point but not one-size-fits-all. Run scenario tests (historical simulation or Monte Carlo) to see how a chosen rate behaves under market shocks, varying lifespans, and different spending patterns. For deeper strategy options see: “Retirement Withdrawal Strategies: Sustainable Income Solutions” (https://finhelp.io/glossary/retirement-withdrawal-strategies-sustainable-income-solutions/).
  1. Account sequencing and tax planning
  • Withdrawal order affects taxes and longevity. Typical sequencing options:
    • Taxable first, then tax-deferred, then tax-free (Roth) — useful when you want to delay RMDs or when tax rates are expected to rise.
    • Tax-deferred first up to a point (to keep below higher tax brackets), then Roth conversions in low-income years.
  • Use partial Roth conversions during low-income windows to manage future RMDs and tax brackets. Our guide on coordinating pension income and IRA withdrawals can help with implementation details: “How to Coordinate Pension Income with IRA Withdrawals” (https://finhelp.io/glossary/how-to-coordinate-pension-income-with-ira-withdrawals/).
  1. Include Social Security timing in the model
  • Deciding when to claim Social Security materially affects required portfolio withdrawals. Delaying benefits increases your monthly benefit (up to age 70) and can reduce portfolio drawdowns in later years. Build claiming age scenarios into your cash-flow model.
  1. Protect against longevity and sequence-of-returns risk
  • Longevity risk: consider guaranteed lifetime income via a portion of assets used to buy an immediate or deferred annuity or purchasing a longevity annuity (deferred income annuity) at older ages.
  • Sequence-of-returns risk: keep a 3–7 year cash buffer to avoid forced selling during market downturns; rebalance your portfolio regularly.

Modeling income: practical approaches and examples

  • Conservative example (couple, 65):

  • Projected spend: $60,000/yr

  • Guaranteed income (pensions + Social Security): $30,000/yr

  • Gap: $30,000/yr from savings

  • Nest egg: $800,000 across taxable, tax-deferred, and Roth

  • Withdrawal approach: draw $20,000 from taxable first (capital gains carry lower tax for long-term holdings), $10,000 from tax-deferred while delaying Social Security until 68. Maintain a 5-year bond ladder cash reserve.

  • Tax-sensitive example (single retiree, 62):

  • Nest egg: $1.2M (Roth $700k, Traditional IRA $500k)

  • Strategy used: draw small distributions from Roth early to avoid spiking taxable income, delay large IRA withdrawals until RMDs start (current law sets RMD age at 73 — see IRS guidance). Then use opportunistic Roth conversions during low-income calendar years to reduce future RMDs and taxes (IRS; Roth rules).

Note: Roth qualified distributions are tax-free if you meet the five-year rule and age/status conditions; traditional IRA distributions are generally taxable as ordinary income (see IRS publications).

Tax rules, RMDs, and up-to-date points (2025)

  • Required Minimum Distributions (RMDs): Under law changes enacted by the SECURE 2.0 Act, the RMD age increased to 73 for many account owners (effective in 2023) and will later increase to 75 for some taxpayers in a future phase-in; consult IRS guidance for personal application (IRS retirement rules: https://www.irs.gov/retirement-plans/retirement-plans-faqs-regarding-required-minimum-distributions).
  • Roth IRAs: qualified withdrawals are tax-free; Roth 401(k) rollovers are common but watch for plan-specific rules.
  • Tax-efficient harvesting: consider selling low-basis taxable assets in years with unusually low income, use tax-loss harvesting where appropriate, and plan partial Roth conversions to smooth taxable income across years.

Tools, modeling techniques, and what to test

  • Monte Carlo simulations: show probability of success across many market-return pathways.
  • Deterministic historical simulations: show how a plan would have fared through past market cycles (e.g., 1970s inflation, 2000s dot-com, 2008 financial crisis).
  • Scenario stress tests: test early-career shocks (large withdrawals in the first 5–10 years), unexpected longevity, and health-related large expenses.
  • Spreadsheets and calculators: start with a retirement income calculator to compare claiming ages, withdrawal rates, and conversion strategies. For more structured help, work with a fee-only advisor or certified planner.

Common mistakes to avoid

  • Treating the 4% rule as a guarantee — it’s a heuristic, not an absolute. Adjust based on market valuations and personal factors.
  • Ignoring taxes and RMD timing.
  • Failing to model Social Security claiming options.
  • Not planning for large health-care or long-term care costs.
  • No contingency plan for prolonged bear markets early in retirement.

Practical annual checklist

  • Re-run cash-flow model with updated account balances and benefit statements.
  • Re-evaluate asset allocation and rebalance where necessary.
  • Check projected RMDs and determine if Roth conversions make sense this year.
  • Confirm emergency cash bucket remains intact (3–7 years’ worth of planned withdrawals).
  • Review estate and beneficiary designations.
  • Revisit Social Security claiming plans if circumstances changed.

When to get professional help

Work with a fiduciary financial planner or tax advisor when:

  • Your portfolio or household finances are complex.
  • You have large traditional balances and need Roth-conversion planning.
  • You’re close to claiming Social Security and need projection modeling.

In my practice I often run three parallel scenarios (conservative, median, optimistic) and stress-test each for a 30-year horizon — that simple exercise typically changes a client’s withdrawal posture and timing for claiming benefits.

Bottom line

A good withdrawal plan is explicit, tax-aware, and stress-tested. Start 5–10 years before retirement, keep a liquid buffer, model Social Security timing, and revisit the plan annually. Combining these elements—along with targeted Roth conversions or partial annuitization when appropriate—helps convert retirement savings into a reliable income stream.
