Annuity

What Is an Annuity?

An annuity is an insurance contract that can accumulate value, provide future payments, or turn a lump sum into a stream of retirement income under the contract's rules. People often hear the word annuity and think of one product, but annuities can be immediate or deferred, fixed, indexed, or variable, and they can be designed for income, accumulation, beneficiary protection, or some combination of those goals.

The most important thing to understand is that an annuity is a contract. The value comes from the specific guarantees, payout rules, fees, surrender terms, tax treatment, riders, and insurer obligations written into that contract.

How an Annuity Works

The owner pays money into an annuity contract, either as a lump sum or through multiple payments. The contract then determines how the money grows, when payments can begin, whether income is guaranteed, what fees apply, and what happens if the owner dies, withdraws early, or chooses a payout option.

Some contracts begin payments soon after purchase. Others defer payments until a later date. Some credit a fixed rate. Some link crediting to an index formula. Some expose value to market subaccounts. Those differences are why annuities should be reviewed by contract design rather than by label alone.

Income Annuities and Accumulation Annuities

An income annuity is designed mainly to provide payments. An accumulation-focused annuity is usually designed to hold and grow contract value before income starts. A deferred annuity can sometimes do both, but the buyer still needs to know whether the real goal is future income, tax deferral, principal stability, market exposure, or a rider-based guarantee.

Retirement planning usually begins with the income need. Product selection should come later.

Common Types of Annuities

• A fixed annuity emphasizes contractual interest crediting and stability.
• An indexed annuity credits interest using an index-linked formula with caps, participation rates, spreads, or similar limits.
• A variable annuity lets the owner allocate contract value among investment options, creating market risk and potential market-linked growth.
• An immediate annuity generally starts payments soon after purchase.
• A qualified annuity is held inside a tax-qualified retirement arrangement, while a nonqualified annuity is funded with after-tax money outside those plans.

Why Retirees Consider Annuities

Retirees usually consider annuities when they want part of their plan to behave more like a paycheck. Social Security and pensions can provide reliable income, but many households also rely on portfolio withdrawals. An annuity can shift part of the income risk to an insurer, especially when the retiree is worried about outliving assets or wants a stronger income floor.

That benefit comes with tradeoffs. Money committed to an annuity may be less liquid. Surrender charges may apply. Fees and rider costs may reduce value. Inflation can weaken fixed payments. Beneficiary outcomes depend on the payout option and contract terms.

Annuity Versus Annuitization

The word annuity can describe the contract itself. Annuitization is a specific decision to convert contract value into a stream of payments under a payout option. A person can own an annuity without having annuitized it yet.

This distinction matters because some contracts are used for tax-deferred accumulation, some are used for future withdrawals, and some are converted into formal lifetime or period-certain payments.

How to Evaluate an Annuity

Start with the retirement problem. Is the household trying to create dependable income, protect a spouse, reduce longevity risk, delay income until later life, preserve liquidity, or manage taxes? Then compare the contract to that problem.

The main review points are income amount, payout timing, fees, surrender charges, insurer strength, inflation exposure, tax treatment, riders, death benefit rules, and how the contract fits with Social Security, cash reserves, portfolio withdrawals, and legacy goals.

The Bottom Line

An annuity is an insurance contract that can accumulate value, provide future payments, or turn money into retirement income. The label alone does not tell you whether the contract is useful. The value depends on the specific job the annuity is supposed to do and whether the contract's guarantees, costs, liquidity, and payout rules actually fit that job.
