Retirement income — where the money comes from

The shift from saving to spending is the most consequential financial transition you'll ever make. During your working years, your paycheck arrives every two weeks and your portfolio just grows in the background. In retirement, the paycheck stops and the portfolio becomes the paycheck. Getting this transition right — where the money comes from, in what order, and how much — is the difference between a 30-year retirement and running out at 85.

The three income sources

1. Social Security

For most retirees, Social Security provides 30–50% of pre-retirement income. The average benefit in 2026 is roughly $1,976/month ($23,700/yr), but high earners who wait until age 70 to claim can receive over $4,873/month ($58,500/yr).

The claiming decision is one of the highest-value financial decisions in retirement. Every year you delay claiming between age 62 and 70, your benefit increases roughly 7–8% — a guaranteed, inflation-adjusted, lifetime return no investment can match.

2. Investment withdrawals

Your portfolio — 401(k), IRA, Roth IRA, brokerage accounts — fills the gap between Social Security and your spending needs. For a couple targeting $80,000/yr in after-tax income, Social Security might cover $40,000, leaving $40,000 that must come from the portfolio.

This is where the 4% rule enters. Developed by financial planner William Bengen in 1994, it says: withdraw 4% of your portfolio in the first year of retirement, then increase that dollar amount by inflation each year. Historically, this approach has sustained a portfolio for at least 30 years in 95% of retirement periods.

A $1M portfolio → $40,000/yr initial withdrawal. A $2M portfolio → $80,000/yr.

The 4% rule is a starting point, not a commandment. Your actual safe withdrawal rate depends on your time horizon, asset allocation, flexibility, and other income sources.

3. Other income

Pensions, rental income, part-time work, and annuity payments can all supplement Social Security and portfolio withdrawals. Every dollar from these sources is a dollar the portfolio doesn't need to provide — reducing withdrawal pressure and extending portfolio longevity.

Withdrawal order: the tax sequencing puzzle

You have three types of accounts, each taxed differently on withdrawal:

• Taxable brokerage — capital gains rates (15–20%) on gains; tax-free on your original contributions
• Traditional 401(k)/IRA — ordinary income rates (10–37%) on everything withdrawn
• Roth IRA — completely tax-free

The default approach most people take — withdrawing from whichever account is most convenient — is almost always wrong. The optimal order considers your current tax bracket, future RMD obligations, and the tax character of each dollar.

A common strategy: in early retirement (before Social Security and RMDs), draw from the traditional IRA first and fill lower tax brackets. Once Social Security starts and pushes income higher, shift to the Roth IRA for tax-free income that doesn't increase your bracket. Use the taxable brokerage for flexibility, taking advantage of lower capital gains rates.

The exact order should be customized annually based on your tax picture — this is one of the most valuable things a good advisor does.

Sequence-of-returns risk

A 30-year average return of 8% doesn't tell you what happens year by year. If the first three years of your retirement produce -20%, -15%, and -10% returns, your portfolio may never recover — even if later years are excellent. This is sequence-of-returns risk, and it's the biggest threat to retirement portfolios.

Why? Because you're withdrawing money during the downturn. A $1M portfolio that drops to $600K while you're pulling $40K/yr has lost 40% to markets and another 7% to withdrawals. Even if markets recover, your reduced balance doesn't benefit as much from the rebound.

The defenses against sequence risk:

• Maintain 2–3 years of spending in bonds and cash so you never sell stocks in a downturn
• Reduce spending during down markets if possible
• Delay Social Security claiming to increase guaranteed income and reduce withdrawal needs
• Consider a more conservative initial allocation than the historical data alone would suggest

What this means for the Hendersons

David and Linda want $80,000/yr in after-tax retirement income. If they delay Social Security to age 70, they might receive a combined $55,000–$60,000/yr. The portfolio needs to provide the remaining $20,000–$25,000 — a very manageable 1.5–1.8% withdrawal rate on $1.4M. This low rate gives them a large safety margin against sequence-of-returns risk and the flexibility to increase spending on travel or grandchildren's education. The key decision is whether to claim at 65 (less per month, more years of payments) or 70 (more per month, fewer years). For most couples with at least one high earner, delaying the higher earner's benefit to 70 is optimal.

What this means for Jordan

Retirement income planning feels distant at 34, but the decisions Jordan makes now — contributing to a Roth IRA, maximizing the 401(k) match, building taxable savings — determine what tools are available in 26 years. The career optionality goal (downshifting at 50) makes this especially relevant: if Jordan semi-retires at 50, the portfolio must bridge a full decade before Social Security eligibility at 62 and an additional 8 years before the optimal claiming age of 70. That bridge requires either substantial taxable savings or very low expenses during the gap years.

Key takeaways

1. Retirement income comes from three sources: Social Security, investment withdrawals, and other income. Most people underestimate the portfolio's role.
2. The 4% rule (withdraw 4% in year one, adjust for inflation) has historically sustained portfolios for 30+ years.
3. Withdrawal order across account types has a significant tax impact — the "convenient" order is almost never the optimal order.
4. Sequence-of-returns risk — poor returns early in retirement — is the biggest threat to portfolio longevity.
5. Delaying Social Security to age 70 increases benefits by 7–8% per year and reduces the burden on your portfolio.

• Sequence-of-returns risk — The risk that large investment losses early in retirement permanently impair portfolio longevity.
• Withdrawal order (tax sequencing) — The strategy of choosing which account to withdraw from in which year to minimize lifetime taxes.
• RMD (Required Minimum Distribution) — Mandatory annual withdrawals from traditional retirement accounts starting at age 73.
• Social Security claiming age — The age at which you begin receiving Social Security benefits (earliest 62, latest 70). Later claiming = higher monthly benefit.
• Bridge period — The years between early retirement and the start of Social Security or pension income, during which the portfolio is the sole income source.
