Annuities in Retirement: Types, Pros and Cons, and When They Actually Make Sense

The Most Misunderstood Product in Retirement

Few financial products provoke stronger reactions than annuities. To one camp, they're expensive, illiquid contracts loaded with fees and surrender charges — products sold, not bought. To another, they're the only thing in the entire financial system that does what every retiree actually wants: guarantee a check that arrives every month for the rest of your life, no matter how long that is or what the market does.

Both camps are right, because "annuity" isn't one product. It's a legal wrapper that covers everything from a dead-simple lifetime income contract to a complex, rider-laden investment vehicle. A single premium immediate annuity and a variable annuity with a guaranteed living benefit have almost nothing in common except the word on the brochure. Lumping them together is like reviewing "vehicles" and concluding that bicycles and semi-trucks are both bad value.

The real question is never "are annuities good or bad?" It's "does this specific annuity solve a problem this specific retiree actually has — and is it the most efficient way to solve it?" This article walks through the major types, what they genuinely cost, the math behind why they work, and the narrow but real set of situations where they belong in a plan.

Why Annuities Exist: Longevity Risk and Mortality Credits

Retirees face a problem no spreadsheet fully solves: nobody knows how long they'll live. A 65-year-old couple has roughly a 50% chance that at least one spouse reaches 92, and a meaningful chance one reaches 100. Plan for the average and you risk running out. Plan for age 100 and you may dramatically underspend, dying with a large unspent balance and a smaller life than you could have lived.

This is longevity risk, and it's uninsurable by an individual acting alone. You can't self-insure against the tail of your own lifespan, because you only get to do it once. Insurance companies can, because they pool thousands of retirees. Some die at 70, some at 100, and the pool pays everyone a higher rate than any of them could safely withdraw on their own.

That extra return is the mortality credit. It's why a 70-year-old buying a lifetime income annuity can receive a payout rate well above what a bond ladder or a safe withdrawal rate would support — the payment includes not just interest and return of principal, but a share of the principal forfeited by those in the pool who don't live as long. No investment strategy can manufacture this, because it doesn't come from markets. It comes from risk pooling.

The practical takeaway: annuities aren't competing with stocks for "best return." They're competing with bonds and cash as the safe, income-producing portion of a plan — and in that role, the mortality credit gives them a genuine edge that grows stronger the older the buyer is.

The Major Types of Annuities

Annuities split along two axes: when they pay (immediate vs. deferred) and how the value grows (fixed, indexed, or variable). Here's how the main categories actually function.

Single Premium Immediate Annuity (SPIA)

The simplest and most transparent annuity. You hand the insurer a lump sum, and payments begin almost immediately — typically the next month — and continue for life (or a chosen period). There's no account value, no statement, no investment decisions. You've converted a pile of money into a paycheck.

A SPIA is the purest expression of the mortality credit. Because it's so simple, it's also the easiest to shop on price: the only real variable is the monthly payment per $100,000 of premium, which you can compare directly across insurers. SPIAs are best for retirees who need to close a guaranteed-income gap now and value certainty over liquidity.

Deferred Income Annuity (DIA)

A DIA works like a SPIA but with a delay. You pay today, and income starts at a future date — often 10 to 15 years out. Because the insurer holds your money longer and because some buyers won't survive to the start date, the eventual payout rate is dramatically higher than a SPIA bought at the same age.

A specific version, the Qualified Longevity Annuity Contract (QLAC), lets you use up to a limited amount of IRA or 401(k) money to buy a DIA whose income can be deferred to as late as age 85. Money inside a QLAC is excluded from Required Minimum Distribution calculations until payments begin — a useful tool for both longevity protection and RMD reduction.

Fixed Annuity (MYGA)

A multi-year guaranteed annuity (MYGA) is the insurance industry's version of a CD. You deposit a lump sum, the insurer credits a fixed interest rate for a set term (commonly 3 to 7 years), and your money grows tax-deferred. At the end of the term you can withdraw, renew, or annuitize.

MYGAs are accumulation tools, not income tools. They appeal to conservative savers who want a guaranteed rate better than a bank CD with tax deferral on the growth. They carry surrender charges if you exit early, so they're for money you genuinely won't need during the term.

Fixed Index Annuity (FIA)

A fixed index annuity credits interest based on the performance of a market index (like the S&P 500), but with a crucial asymmetry: your principal is protected from market losses, and in exchange your upside is capped or limited by a participation rate. In a year the index rises 20%, you might be credited 6%. In a year it falls 20%, you're credited 0% — you don't lose.

FIAs are complex. Caps, participation rates, and spreads can change annually at the insurer's discretion, and the headline crediting methods are often harder to evaluate than they look. But the core proposition — no market losses, some market-linked growth — is real and appeals to retirees who can't stomach volatility but want more than a fixed rate. Many FIAs add an optional guaranteed lifetime withdrawal benefit (GLWB) rider that turns the contract into an income product without giving up access to the account value.

Variable Annuity (VA)

A variable annuity invests your premium in subaccounts (essentially mutual funds) inside a tax-deferred, insurance wrapper. The account value rises and falls with the markets. On their own, VAs are often the most expensive and least defensible annuities — mortality and expense charges, subaccount fees, and rider costs can stack to 2–3%+ annually.

Their justification, when there is one, is a guaranteed living benefit rider that promises a minimum income or withdrawal base regardless of how the underlying investments perform. For a retiree who wants market participation and a contractual income floor, that combination can be valuable — but the fees are high enough that the product must be evaluated rider-by-rider, not accepted on the sales pitch.

What Annuities Actually Cost

The "annuities are expensive" criticism is true for some types and misleading for others. Costs come in three forms, and they vary enormously by product.

Income annuities (SPIA/DIA) have no explicit fee. You don't pay an expense ratio. Instead, the "cost" is embedded: the insurer keeps a margin between what they earn on your premium and what they pay you, and you give up liquidity and any upside. The honest way to evaluate a SPIA is to compare its payout rate against insurers and against what you'd safely withdraw from a bond portfolio — not to hunt for a fee that isn't itemized.

Fixed and index annuities cost you in opportunity and flexibility. The insurer credits a rate below what they earn, and surrender charges (often 7–10 years, declining annually) lock up your principal. FIAs additionally cap your upside — the gap between the index return and your credited return is the real cost, and it's variable.

Variable annuities and riders carry explicit, stackable fees. This is where the reputation comes from. A VA might charge 1.2% mortality and expense, 0.9% in subaccount fees, and 1.1% for a living benefit rider — over 3% annually, compounding against your returns for decades.

The Real Pros and Cons

The Genuine Advantages

• Guaranteed lifetime income. No other product can promise a check for life that you cannot outlive. For the floor of a retirement plan, this is uniquely valuable.
• Longevity risk transfer. You offload the "what if I live to 100" problem to an entity that can actually absorb it.
• Mortality credits. Lifetime payout rates exceed what a bond portfolio of equal safety can sustain, especially at older ages.
• Behavioral protection. A guaranteed paycheck keeps retirees from panic-selling in downturns and lets them spend confidently rather than hoarding out of fear.
• Tax deferral. Growth inside an annuity compounds tax-deferred (though distributions of gains are ordinary income, not capital gains).
• Principal protection (fixed/FIA). Conservative retirees get growth potential without downside market risk.

The Genuine Drawbacks

• Illiquidity. Income annuities are largely irreversible; deferred annuities lock money up during surrender periods. This money is no longer available for emergencies or opportunities.
• Inflation erosion. Most annuity payments are level. A fixed $2,000/month loses roughly a quarter of its purchasing power over a decade at 3% inflation. Inflation-adjusted (COLA) annuities exist but start with a much lower payment.
• Loss of legacy (income annuities). A basic life-only SPIA stops paying at death, leaving nothing for heirs. Period-certain and cash-refund options preserve some value but reduce the payout.
• Complexity and opacity (FIA/VA). Caps, participation rates, spreads, and rider mechanics are hard to evaluate and can change. Complexity favors the seller.
• Cost (variable annuities). Stacked fees can quietly consume 2–3%+ per year.
• Credit risk. Guarantees are only as strong as the issuing insurer. They're backed by the company and, secondarily, by state guaranty associations up to statutory limits — not by the federal government.

When an Annuity Actually Makes Sense

Setting aside sales pressure, there's a clear-eyed set of situations where an annuity is the right tool — and a larger set where it isn't.

An annuity often makes sense when:

• There's a guaranteed-income gap below essential expenses. If Social Security and any pension don't cover the non-negotiables — housing, food, healthcare, insurance — a SPIA can fill that gap so essentials never depend on the market. This is the single strongest use case.
• The retiree's primary fear is outliving their money. For clients whose anxiety is longevity, not legacy, transferring that risk is worth the trade-offs.
• Longevity hedging at the tail. A small DIA or QLAC starting at 80–85 efficiently protects against a very long life without locking up most of the portfolio.
• The retiree is constitutionally unable to tolerate market volatility. If the alternative is selling equities in every downturn, a guaranteed floor that keeps them invested elsewhere may produce a better real-world outcome.

An annuity usually does not make sense when:

• Guaranteed income already covers essential expenses — the floor is built, and additional annuitization just sacrifices liquidity and upside.
• The money is needed for liquidity, emergencies, or a near-term goal.
• The dominant goal is leaving a large legacy, where a life-only income annuity works directly against the objective.
• The product is a high-fee variable annuity whose riders don't clearly solve a stated problem.
• It would mean annuitizing too large a share of the portfolio, leaving nothing to grow against inflation.

A Worked Example

Consider Linda, 68, single, with $5,200/month in essential expenses. Her Social Security provides $2,600/month — exactly half. She has $900,000 in a traditional IRA and brokerage account, no pension, and her biggest fear is running out of money in her 90s (her mother lived to 96).

Rather than annuitizing everything or nothing, a layered approach uses an annuity surgically:

• Close the essentials gap. Linda uses $300,000 of her IRA to buy a SPIA paying roughly $1,950/month for life. Combined with Social Security, her guaranteed income is now ~$4,550/month — covering 88% of essentials, none of it exposed to markets.
• Hedge the deep tail. She allocates a further $50,000 to a QLAC with income starting at 82, adding several hundred dollars a month of guaranteed late-life income and trimming her future RMDs.
• Keep the rest growing. The remaining ~$550,000 stays invested for lifestyle spending, inflation protection, liquidity, and legacy.

The result: Linda's essentials are nearly fully guaranteed, her single greatest fear — outliving her money — is structurally addressed, and the majority of her portfolio remains liquid and growth-oriented. She annuitized roughly 39% of her assets, not 100%, and bought exactly the protection she needed without surrendering flexibility she'll want.

Why Annuities Matter for Advisors

Annuities are where advisor judgment matters most, precisely because the products are so easy to misuse. The advisor's job isn't to be pro- or anti-annuity — it's to diagnose whether a guaranteed-income gap exists, quantify it, and determine whether an annuity is the most efficient way to close it versus bonds, a delayed Social Security claim, or a different withdrawal strategy. Framed that way, the annuity stops being a product to sell and becomes a tool to deploy — sometimes, in the right amount, for the right client. That framing also protects the advisor: a documented analysis showing why an annuity was or wasn't recommended is exactly the kind of suitability rationale a compliance-first practice should be able to produce on demand.

How RetirementForge Helps

RetirementForge lets advisors quantify the guaranteed-income gap before discussing any product. The Income Gap Calculator shows exactly how much of a client's essential expenses are covered by Social Security and pensions — and how much remains for a potential annuity allocation. From there, the Strategy Lab lets you model an annuity layer alongside portfolio withdrawals and Social Security timing, so clients can see how a SPIA or DIA changes their monthly income, their floor coverage ratio, and their longevity protection — all in one shared session view. Get started free and quantify your client's income gap in minutes.
