What is the Primary Reason People Buy Annuities

The primary reason people buy annuities is to create reliable income that cannot be outlived. For most retirees, the central financial fear is simple: running out of money before running out of time. Annuities are designed specifically to address that fear — converting accumulated savings into guaranteed payments that continue for a defined period or for the rest of the annuitant’s life, regardless of how long that life lasts. According to a LIMRA survey, guaranteed income was the top reason respondents gave for purchasing an annuity, with most buyers planning to use it to either supplement Social Security and pension income or to generate lifetime income as a standalone retirement paycheck. A BlackRock study found that 97% of annuity owners say their contracts help them worry less about running out of money. That result is not a coincidence — it reflects what the product is designed to do.

Retirement planning has changed significantly over the past several decades. Traditional employer pensions once provided guaranteed income for life for a large portion of the working population, but many of these programs have disappeared or become less common as the workforce shifted toward defined-contribution plans. As a result, individuals are increasingly responsible for designing their own retirement income strategies without the safety net that a pension once provided. Annuities are frequently used to fill this gap — functioning as a personal pension replacement that converts accumulated retirement savings into predictable lifetime payments that a portfolio of stocks and bonds cannot match in certainty. Understanding the full spectrum of benefits of annuities across different product types helps clarify why guaranteed income is both the primary reason and the most sustainable use case for this category of products.

The Primary Reasons People Buy Annuities — At a Glance

Before examining each reason in depth, the table below maps the core motivations that drive annuity purchases against the annuity structures that best address each one — so the match between planning need and product type is clear from the outset.

Guaranteed Income in Retirement — The Primary Driver

The most common and most clearly documented reason people purchase annuities is to secure reliable retirement income — income that is guaranteed to continue for life regardless of market performance, interest rate movements, or how long the annuitant lives. When individuals convert part of their retirement savings into an annuity, they transfer longevity risk to the insurance company. In exchange for the premium paid, the insurer guarantees income payments according to the terms of the contract. That contractual guarantee is the defining feature that no portfolio of stocks and bonds can replicate, because a portfolio is finite and a lifetime income guarantee is not.

Retirees often combine annuities with other guaranteed income sources to create a stable financial foundation. Coordinating an annuity’s guaranteed payments with Social Security planning is one of the most common approaches — using each source to cover specific expense categories so that essential living costs are met regardless of what happens to discretionary investment accounts. For those with pension income as well, the three-source combination of Social Security, pension, and annuity can create an income floor that reduces or eliminates dependence on portfolio withdrawals for basic expenses. Our resource on guaranteed income from annuities walks through how different annuity structures — immediate, deferred, and income rider-based — create that guaranteed floor and how each fits different retirement timelines. The challenge of not running out of money in retirement is most directly solved by owning income that cannot run out — which is what a lifetime annuity, by contractual definition, provides.

Protecting Retirement Savings From Market Volatility

A second major reason people buy annuities is to protect accumulated savings from market volatility — particularly in the years immediately before and after retirement, when a severe portfolio decline can do the most lasting damage. Investment markets can experience periods of significant and prolonged decline. For a retiree who is simultaneously withdrawing from a portfolio, those declines can permanently reduce the portfolio’s ability to sustain income even if markets eventually recover. This is the core problem that sequence-of-returns risk describes — and it is one of the most powerful arguments for holding at least a portion of retirement savings in a vehicle that is insulated from market performance entirely.

Fixed annuities and fixed indexed annuities provide principal protection as a contractual feature. The original investment is not exposed to market losses — in a fixed indexed annuity, a negative index year credits 0% rather than a loss, and in a fixed MYGA, the declared rate applies regardless of what markets do. For individuals approaching retirement, protecting accumulated savings can be just as important as generating additional growth. Understanding broader downside protection strategies in bear markets helps frame where annuities sit relative to other risk management tools — and why the combination of principal protection and guaranteed income potential makes certain annuity types a natural fit for conservative retirement dollars specifically in the transition zone from accumulation to distribution. A thoughtful investment risk analysis that maps which portions of a retirement plan can tolerate market volatility and which cannot is the foundation for determining how much to allocate to guaranteed vehicles versus growth-oriented ones.

Tax-Deferred Growth — The Accumulation Advantage

A third reason individuals choose annuities is the tax-deferred growth potential they offer. Earnings within an annuity contract — whether interest credited in a fixed annuity or index-linked gains in a fixed indexed annuity — are typically not taxed until funds are withdrawn. This allows gains to compound over time without annual income tax reducing the invested base. The compounding benefit of tax deferral is most significant over long holding periods and for investors in high income tax brackets during the accumulation years who expect a lower bracket in retirement when withdrawals begin.

Tax-deferred growth can be particularly valuable for individuals who have already maximized contributions to qualified retirement accounts such as 401(k) plans or IRAs. In those situations, non-qualified annuities — funded with after-tax dollars outside a retirement account — may serve as an additional accumulation vehicle with no IRS contribution limits. Understanding the mechanics of a deferred annuity and how tax deferral interacts with withdrawal timing helps evaluate whether this advantage is meaningful for a specific household’s tax profile. The important counterpoint is that annuity gains are taxed as ordinary income when withdrawn — not at the lower long-term capital gains rate — which means the net benefit of tax deferral must be weighed against that ordinary income treatment at distribution.

Estate Planning and Beneficiary Protection

Annuities can also serve estate planning objectives. Most annuity contracts allow owners to designate beneficiaries who will receive remaining contract value or death benefit upon the owner’s death — and that transfer typically passes outside of probate, directly to named beneficiaries, which can simplify estate administration and preserve timing. Some annuity designs include return-of-premium death benefit provisions that guarantee heirs receive at least the original premium paid even if the owner passed away before receiving equivalent income payments. Understanding annuity beneficiary death benefits and the election options available at the time of distribution is an important part of evaluating annuities for estate planning purposes.

Annuities do not receive a step-up in cost basis at the owner’s death the way taxable brokerage accounts typically do — beneficiaries owe ordinary income tax on the gain portion when they receive distributions from an inherited annuity. This distinction matters for estate planning because it affects how annuities should be positioned relative to other assets in the overall plan. Some retirees also coordinate annuity income planning with long-term care preparation through resources such as the long term care playbook, ensuring that healthcare costs in later life do not undermine the income stream the annuity is designed to protect. By combining income planning, tax-deferred growth, and beneficiary planning within a single contract, annuities can serve multiple planning roles simultaneously — which is part of what makes them versatile tools in comprehensive retirement design.

Longevity Risk — The Problem That Makes Annuities Uniquely Suited

Longevity risk — the risk of outliving financial resources — is the defining problem of modern retirement planning. A person who retires at 65 today can reasonably expect to live another 20 or more years, according to actuarial data, and a significant portion of that population will live into their late 80s or 90s. A retirement portfolio designed to last 20 years may be financially stressed by year 25, and the last years of a long life are often when healthcare costs are highest and earning ability is lowest. Annuities address this specific problem in a way that no other financial product can — by contractually guaranteeing that income continues regardless of how long the annuitant lives, transferring the actuarial risk of longevity to the insurer who can pool it across thousands of policyholders.

For pure longevity protection — income that begins later in retirement when other sources may be depleted — a Qualified Longevity Annuity Contract (QLAC) specifically addresses the later-years income problem while reducing required minimum distributions in the years before income begins. For immediate longevity protection — income that starts now and continues for life — a single premium immediate annuity converts a lump sum into a lifetime income stream that begins within 30 days. The right structure depends on when the income is needed and how it fits alongside other retirement income sources — but the underlying motivation is the same across all designs: creating income certainty that outlasts the unknown duration of retirement.

Why Annuities Remain Popular for Retirement Planning

Ultimately, the primary reason people buy annuities is financial certainty. Retirement can last for three or more decades, and most retirees prefer having at least a portion of their income guaranteed for life rather than managed entirely through market-dependent withdrawals that are vulnerable to bad sequence timing. Annuities provide that level of certainty by converting accumulated savings into reliable income payments that the insurance company is contractually obligated to make. When used appropriately — matched to the specific planning need they address and positioned correctly within a broader income plan — annuities can reduce financial stress during retirement and allow individuals to focus on enjoying their retirement years rather than managing the mathematics of portfolio sustainability.

For individuals evaluating different retirement structures, annuities often serve as the income floor that supports a more aggressive posture with remaining assets. Knowing that essential expenses are covered by guaranteed income can allow a household to keep other assets invested longer and with more risk tolerance — which is itself a planning advantage. Exploring the best annuity rates for seniors, considering whether a bonus annuity with lifetime income fits the accumulation and income timeline, or evaluating whether annuities with inflation protection address the purchasing power concern are all refinements of that central question: what is the most effective way to convert what you have saved into income you cannot outlive? Understanding both the benefits and the drawbacks of annuities across product types is the essential foundation for making that determination with full information rather than partial understanding.
