Annuities vs Stock Market: Which Belongs in Your Retirement Plan?

The Question Underneath the Question

"Should I put my money in an annuity, or keep it in the market?" is one of the most common retirement planning questions out there. The framing, though, sets up a comparison that doesn't really fit how either product is meant to be used.

It's a bit like asking whether a house should have a roof or walls. Both are necessary. They do different jobs, and neither is trying to do the other's job.

The stock market is a growth engine. Over time, it's designed to make money multiply — with the trade-off that it can also shrink temporarily (or permanently, if an investor sells at the worst possible moment). Annuities function more as a safety net. They're built to protect money and convert it into guaranteed income — with the trade-off that the growth ceiling sits lower. Annuities generally won't outperform the market over a long horizon. That isn't really what they're for, and any honest comparison has to start by acknowledging that.

So the better question isn't which one is better. It's how much of each makes sense, and at what point.

Side-by-Side Comparison

A Realistic Look at Returns

The stock market's long-term average is roughly 10% annually (S&P 500, including dividends). That's well established. Over 20, 30, or 40 years, equities have been the single most effective wealth-building tool available to ordinary investors.

Annuities aren't going to match that. A fixed annuity paying 5.25% won't outpace stocks over 20 years. Neither will a fixed index annuity averaging 4–6%. If pure return maximization is the only metric, the stock market wins straightforwardly.

What that 10% average doesn't capture, though, is just as important:

The path matters as much as the destination. That 10% average is made up of years of +30% and years of -30%. Retiring into a -30% year and beginning to withdraw from a shrinking portfolio can permanently impair a retirement plan. This is sequence of returns risk, and it's one of the biggest threats to retirees who are fully invested in the market.

You don't actually get the average — you get the sequence. Two retirees with identical 20-year average returns can have very different outcomes depending on whether the rough years come early or late. Early losses paired with withdrawals are particularly damaging. Later losses, after years of growth, are usually more manageable.

Discipline is part of the deal. That 10% average assumes investors stayed put through every crash, correction, and alarming headline. Studies repeatedly find that actual investor returns trail fund returns by 3–4% because people sell during downturns and miss the recovery.

Risk: Where the Real Difference Lives

Look at what you're actually risking under each approach.

Stock Market Risks

• Market risk: Stocks can and do lose value. The S&P 500 has experienced drawdowns of 20% or more roughly every 5–7 years.
• Sequence of returns risk: Poor early-retirement returns can permanently deplete a portfolio.
• Behavioral risk: Your own emotions are often the biggest threat. Selling during a crash locks in losses.
• Longevity risk: Living longer than the portfolio can sustain withdrawals.
• No income guarantee: The 4% rule is a guideline, not a contractual promise.

Annuity Risks

• Opportunity cost: Money in an annuity doesn't participate fully in market booms.
• Inflation risk: Fixed payments lose purchasing power over time.
• Liquidity risk: Surrender charges penalize early withdrawals.
• Insurance company risk: Guarantees depend on the carrier (mitigated by using A-rated carriers and state guaranty associations).
• Tax treatment: Annuity withdrawals are taxed as ordinary income, which is higher than capital gains rates.

The shapes of those risks are different. Stock market risks are about losing money you currently have. Annuity risks are about missing growth you might otherwise have captured. Those are very different problems financially and psychologically.

The Tax Picture

This is one area where stocks have a meaningful advantage that doesn't get enough attention.

Stock market investments held for more than a year are taxed at long-term capital gains rates: 0%, 15%, or 20% depending on income. Qualified dividends get the same treatment. For most retirees, that's significantly lower than ordinary income tax rates.

Annuity withdrawals are taxed as ordinary income — potentially 22%, 24%, or 32% depending on your bracket. There's no capital gains treatment and no step-up in basis at death (unlike with appreciated stocks).

So while annuities offer tax deferral (no annual tax on growth), the eventual tax rate on withdrawals is generally higher. For large sums over long horizons, that difference can be substantial.

When Staying in the Market Makes Sense

Keeping money in the market often makes sense if:

• You're more than 10 years from retirement and have time to recover from downturns
• You have a high risk tolerance and can stay disciplined through crashes
• You're in a low tax bracket (annuity tax deferral provides less benefit)
• You have adequate emergency funds and guaranteed income from other sources (Social Security, pension)
• You want maximum long-term growth and are willing to accept volatility
• You're investing for legacy/inheritance — stocks receive a step-up in basis at death, annuities do not

When an Annuity Makes More Sense

Shifting some money into an annuity often makes sense if:

• You're within 5–10 years of retirement and can't afford a major market loss
• You need guaranteed income to cover essential expenses in retirement
• Market volatility is interfering with your sleep, and you might make emotional decisions during a downturn
• You want to eliminate sequence of returns risk for a portion of your savings
• You've already maxed out tax-advantaged accounts and want additional tax-deferred growth
• You don't have a pension and want to create a pension-like income stream with an income annuity

The Practical Approach: Use Both

For most people, the more productive approach is to use both — not as a sales recommendation, but as a planning framework:

Build a guaranteed income floor. Calculate your essential monthly expenses — housing, food, healthcare, insurance, utilities — and figure out how much Social Security covers. The gap between essential expenses and Social Security is the amount that needs to be guaranteed. An annuity can fill that gap.

Keep the rest invested. Spending above the essentials — travel, hobbies, gifts, discretionary expenses — can come from a market-invested portfolio. If markets drop 20% and discretionary spending is trimmed for a year, that's uncomfortable but not catastrophic. The essentials are still covered.

This two-bucket structure means there's no need to sell stocks in a down market to pay the mortgage. The annuity income handles the must-haves. The portfolio handles the nice-to-haves.

Example:

• Essential monthly expenses: $5,000
• Social Security income: $3,000
• Income gap: $2,000/month
• Annuity needed: Enough to generate $2,000/month in guaranteed income
• Remaining savings: Invested in a diversified stock/bond portfolio for growth and discretionary spending

What About "Just Buying Index Funds"?

A common counterpoint: "Why would I buy an annuity when I can just put everything in a low-cost S&P 500 index fund and earn 10%?"

For a 35-year-old with a high risk tolerance, a stable income, and decades until retirement, that's a reasonable position. An annuity may not have a clear role yet.

But picture a 60-year-old with $800,000 in retirement savings, no pension, and a planned retirement date three years out. Having that entire $800,000 riding on market performance during the first years of retirement is a recipe for sleepless nights — and potentially serious financial harm if a downturn arrives at the wrong moment.

A "stay in index funds" strategy assumes you'll never need to sell at a bad time. It assumes the next 20 years look something like the last 20. And it assumes the emotional steadiness to watch a portfolio drop $200,000+ without intervening. Those are big assumptions, and annuities are one way to remove them.

The Bottom Line

Annuities and stock market investments aren't competitors — they're teammates with different positions. The market is the offense: it's how wealth gets built over time. An annuity is the defense: it's how wealth gets protected and converted into income you can't outlive.

The most common mistake isn't choosing one over the other — it's going 100% in either direction. All stocks and no guarantees is risky. All annuities and no growth leaves money on the table.

The right balance depends on age, income needs, risk tolerance, and how much of a retirement plan can reasonably be left to chance.
