CD vs Investing in S&P 500 (2026): Sequence Risk for Retirees

The CD-vs-S&P comparison depends entirely on whether you're accumulating or drawing income. For someone 30 years from needing the money, the S&P 500 wins by such a wide historical margin (10%/yr vs 4.4%/yr compounded over 30 years = $5.5M vs $920K on a $250K start) that the CD strategy is borderline irrational.

For a 65-year-old drawing $50K/year in retirement income, the comparison flips. The S&P 500's average annual return is 10%, but the actual sequence of returns matters enormously. A 30% drop in year 1 of retirement, combined with $50K of withdrawals, means selling shares at depressed prices. That permanently destroys capital that would otherwise have compounded back. This is called sequence-of-returns risk and it's why retirees can't simply hold 100% equities.

The right structure for a retiree isn't CD-or-S&P; it's a "bucket" approach: 1-5 years of expenses in CDs/cash (the spending buffer), 5-15 years in bonds/conservative income (the bridge), and the rest in equities (the growth engine).

Side-by-side comparison

When CDs win

• You're 65+ and drawing income. The CD provides sequence-of-returns protection. Keep 3-5 years of spending in CDs.
• You have a defined expense in 1-5 years (wedding, college, surgery, home purchase). The S&P 500 might drop 30% before you need it. CDs guarantee the dollars.
• You can't tolerate seeing -30% on a statement. Behavioral capacity matters. Some investors panic-sell at bottoms; the CD never tests this.
• You're nearing or in retirement and want a guaranteed income floor. CDs cover the floor; S&P upside is on top.
• You're in a high-tax-bracket year and adding investment income would push you up. CDs in IRAs avoid taxable interest; S&P 500 dividends and gains compound similarly in tax-deferred accounts.

When S&P 500 ETF (VOO, SPY, IVV) wins

• You're 30-50 years from needing the money. The historical edge is so large that CDs are dramatically suboptimal.
• You can tolerate market volatility. If you can stomach a -30% year without selling, the long-term math heavily favors equities.
• You're already covered for fixed income / income floor. Adding more CDs is unnecessary; add growth tier.
• You want long-term inflation protection. Equities have outpaced inflation by 6-7% annually over long horizons. CDs barely match it after tax.
• You're in a low tax bracket. Qualified dividends and long-term capital gains rates (0%, 15%) often beat ordinary-income CD interest tax treatment.

Worked example: $250,000 over the planning horizon

You're 65, retiring with $1.2M and need $60K/yr from the portfolio (about a 5% withdrawal rate). Three strategies:

Option A: All $1.2M in 5-year CD ladder at 4.40%.
Year 1 interest: $52,800. Need to draw an additional $7,200 from principal. After 30 years (if rates stay at 4.40%), principal is nearly intact, but income hasn't grown. $60K in year 30 buys roughly $33K of today's purchasing power (assuming 2% inflation). Real value of income has been cut nearly in half.

Option B: All $1.2M in S&P 500 ETF.
Long-term expected return ~10%, but year-1 sequence risk is the killer. If markets drop 30% in year 1, the portfolio falls to $840K, and your $60K withdrawal becomes 7.1% of remaining principal, a much harder draw to sustain. Bad sequence in years 1-5 has historically led to ~30% chance of portfolio failure by age 90.

Option C: Bucket strategy. $300K in CDs (5 yrs of expenses), $300K in bond ETFs, $600K in S&P 500.
Year 1 income: draw $60K from CD bucket. CD ladder refilled annually from bond ETF distributions and modest S&P sales when markets are up. Equity allocation has time to ride out any drawdown without forced selling. Historical Monte Carlo: 95%+ success rate over 30 years.

The optimal answer for retirees is rarely either-or. It's a structured allocation where CDs protect the near-term and equities power the long-term.

Tax implications

CDs: interest taxed annually as ordinary income, federal and state. No tax efficiency.

S&P 500 ETF (in a taxable account): qualified dividends (typically 1.5-2.0% yield in 2026) taxed at 0%, 15%, or 20% depending on income. Capital gains: tax-deferred until sale. When sold, taxed at long-term capital gains rates if held over 1 year. Significant tax efficiency vs CDs.

In tax-deferred accounts (IRA, 401(k)): both CDs and equities grow tax-deferred; no tax efficiency difference. Withdrawals are ordinary income in either case.

In Roth accounts: both grow tax-free; no tax difference, but you'd typically want equities (highest expected return) in Roths to maximize tax-free compounding.

Where a MYGA fits in

For the conservative income tier of a retirement portfolio, MYGAs at 5.40-5.85% beat CDs on yield and offer tax deferral until withdrawal. A MYGA ladder (3, 5, 7-year terms) can replace CDs in the "bond bucket" of the bucket strategy, capturing 100+ bps of additional yield with similar safety profile (state guaranty fund vs FDIC).

The 65-year-old in the worked example might allocate: $300K CDs (1-5 yr spending), $300K MYGA ladder (years 6-10 spending, tax-deferred until needed), $600K S&P 500 (years 11-30+ growth tier). This three-bucket structure with MYGA as the middle bucket has been the standard retirement income plan for the past decade.
