Annuities and Pensions

Most of this site is about spending down a portfolio. Pensions and annuities solve the same problem from the opposite direction: instead of managing money so it lasts a lifetime, they convert money into income that is contractually promised to last a lifetime. Understanding how that conversion works — and what it costs — matters even for people who never buy one.

From pensions to 401(k)s: who holds the risk

For much of the twentieth century, the centerpiece of American retirement was the defined-benefit pension: the employer promised a monthly check for life, and the employer's fund bore the investment risk and the longevity risk. Over the past several decades that model has largely given way to defined-contribution plans — 401(k)s and their cousins — in which the worker owns an account balance and bears both risks personally. The shift is why this site exists: "will my pension check arrive?" was an employer's actuarial problem, while "how much can I withdraw from my account?" is now each household's problem. Annuities are, in essence, a way to buy back the old arrangement with part of the new one's balance.

Pension elections: the survivor option

Retirees lucky enough to have a pension face a one-time menu of payout options. A single-life payout pays the largest monthly amount but stops entirely at the retiree's death. A joint-and-survivor option pays a smaller monthly amount, but payments continue — in whole or in reduced part — for the lifetime of a surviving spouse. The election is typically made once, at retirement, and cannot be revisited when circumstances change.

The stakes are concentrated on the survivor: a household that takes the larger single-life check enjoys higher income while both spouses are alive and then loses that income entirely at the pensioner's death, exactly when the survivor may need it. Federal law generally requires a married participant's spouse to consent in writing before a survivor benefit is waived — a hint at how consequential the choice is.

Lump sum or monthly checks?

Many pensions also offer a lump sum in place of lifetime payments, and some employers periodically offer buyouts to former employees. Neither choice is inherently right; the factors that push households in each direction are well understood:

• Health and longevity. Lifetime payments are worth more to people likely to live long, less to those with serious health issues.
• Spousal protection. An annuity with a survivor option protects a spouse automatically; a lump sum protects a spouse only as well as it is managed.
• Inflation. Most private pensions pay a fixed nominal amount, which loses purchasing power every year; a lump sum can be invested in assets that may keep pace.
• Control and bequest. A lump sum remains part of the household's estate and emergency reserves; annuitized money generally does not.
• Counterparty strength. Monthly checks are only as good as the plan or insurer behind them, which is why the backstops discussed below exist.

How an immediate annuity works — and why pooling pays

A single-premium immediate annuity (SPIA) is the simplest product in the family: hand an insurer a lump sum, and it pays a fixed amount every month for the rest of your life, starting now. What makes the arrangement interesting is the mortality credit. The insurer pools thousands of annuitants and knows — statistically, not individually — how long the group will live. Premiums from those who die earlier than average remain in the pool and fund the payments of those who live longer. Every annuitant therefore receives more per month than they could safely generate from bonds alone, because each payment is part investment return, part return of principal, and part transfer from the shorter-lived members of the pool. No individual investor can replicate that third component, because no individual can pool away their own longevity risk.

The price of the deal is symmetrical: the lump sum is gone. A retiree who dies early has, in effect, subsidized the pool, and the money is no longer available for heirs or emergencies (except to the extent optional guarantee features, which reduce the monthly payment, are attached).

Longevity insurance: deferred income annuities and QLACs

A deferred income annuity inverts the timing: pay the premium now, but income begins years or decades later — often at an advanced age. Purchased at retirement with income starting late in life, it functions as pure longevity insurance: a relatively small premium buys meaningful income precisely in the "what if I live to ninety-five?" scenario, letting the rest of the portfolio be planned over a defined horizon instead of an open-ended one. Because many buyers will not live to collect, deferral makes the mortality credits especially powerful.

The QLAC — qualified longevity annuity contract — is a creature of the tax code: a deferred income annuity bought inside a retirement account such as an IRA or 401(k). Within limits set by regulation, the money used to buy a QLAC is excluded from the balance on which required minimum distributions are computed until its income begins, which the rules allow to be deferred as late as age 85. The dollar limits change over time and are best checked at the IRS directly.

What fixed annuities do not cover: inflation

A fixed annuity payment solves longevity risk completely and inflation risk not at all. A level monthly check buys a little less every year, and over a multi-decade retirement the erosion compounds substantially — the same quiet force described in Inflation: The Quiet Risk. Some annuities offer payments that increase by a fixed percentage each year, purchased with a lower starting payment; true CPI-linked commercial annuities are rare in the U.S. market. This exposure is one of the strongest arguments for treating an annuity as one layer of a plan rather than the whole plan.

Variable and indexed annuities: a complexity caution

Beyond the simple fixed products lies a large category of variable annuities and indexed annuities, which tie payments or account values to market performance through formulas involving caps, participation rates, spreads, riders, and surrender schedules. These are legitimate products that suit some situations, and this article takes no position on them — but they are, objectively, harder to evaluate. The fees and the formulas interact in ways that even diligent buyers struggle to price, and comparison shopping across products with different formulas is genuinely difficult. A useful neutral rule of thumb from regulators' educational materials: complexity is a cost in itself, and a product one cannot explain is difficult to plan around.

Who stands behind the promise

An annuity is an insurance contract, so the promise is only as strong as the insurer making it. Insurers are regulated at the state level and rated by independent agencies, and every state operates a guaranty association that provides a backstop if a licensed insurer fails — conceptually similar to deposit insurance, but with coverage limits that vary by state and product type. Private pensions have their own federal backstop in the Pension Benefit Guaranty Corporation, likewise subject to limits. These backstops are real but bounded, which is why insurer strength appears on the decision-factor list above.

Floor-and-upside: the role annuities actually play

In practice, few households annuitize everything, and few should want to — the all-annuity retirement gives up liquidity, bequests, and inflation protection in one stroke. The framework many planners use instead is floor-and-upside, described more fully in Withdrawal Strategies Beyond the 4% Rule: add up essential expenses, count guaranteed income from Social Security and any pension, and consider annuitizing just enough to close the gap so that essentials are covered for life no matter what markets do. The remaining portfolio then funds the flexible, discretionary layer — and because that layer can bend in bad markets, the portfolio behind it can be invested for growth.

The annuity most people already own

One more fact belongs in any discussion of annuities: Social Security is one — a government-backed, inflation-adjusted lifetime annuity with survivor benefits. Benefits can start as early as age 62 or as late as age 70, and each year of delay permanently increases the monthly check. Viewed through an annuity lens, delaying — spending from the portfolio for a few years in exchange for a larger inflation-adjusted lifetime income — is equivalent to buying an annuity, and it is widely regarded as the cheapest inflation-adjusted annuity available at any price, because no commercial insurer matches its combination of CPI indexation, survivor protection, and government backing. How the claiming-age math works is covered in Social Security Basics.
