Summary:

An annuity is a financial contract between an individual and an insurance company in which the insurer provides a guaranteed stream of income payments in exchange for a lump sum or series of contributions.

Annuities come in several forms, each suited to a different retirement income goal.

Fixed annuity: Pays a set interest rate and predictable income, best for risk-averse retirees who want stability.
Variable annuity: Ties returns to investment subaccounts, offering growth potential with higher risk.
Indexed annuity: Links returns to a market index like the S&P 500 while limiting downside loss.
Immediate annuity: Begins paying out within a month of purchase, designed for retirees who need income right away.

Outliving your savings is one of the most concrete financial risks in retirement. An annuity addresses that risk directly by converting a pool of money into a predictable income stream you can count on for years — or for life.

How an annuity works

You pay an insurance company a lump sum (or periodic premiums), and they agree to return it to you — with growth — as regular payments starting at a future date or immediately.

The contract has two phases: the accumulation phase, when your money grows tax-deferred, and the distribution phase, when the insurer sends you income payments. According to FINRA, annuities are among the most complex financial products sold to retail investors, so understanding the contract terms before signing is essential.

Types of annuities

The right annuity depends on how much risk you’re willing to accept and when you need income to begin.

Type	How returns work	Best for
Fixed	Guaranteed interest rate set by insurer	Predictable, low-risk income
Variable	Tied to investment subaccounts (stocks, bonds)	Growth potential with market exposure
Fixed indexed	Linked to an index; gains capped, losses floored	Upside participation with downside protection
Immediate	Fixed or variable; payments begin within 30 days	Retirees needing income now
Deferred	Fixed, variable, or indexed; payments begin later	Pre-retirees building future income

Annuity payout options

When the distribution phase begins, you choose how payments are structured. Each option involves a trade-off between income size and income security.

Life only: Pays the highest monthly amount but stops at death — no benefit to heirs.
Life with period certain: Guarantees payments for a minimum number of years (e.g., 10 or 20) even if you die early.
Joint and survivor: Continues payments to a surviving spouse or beneficiary, typically at a reduced rate.
Fixed period: Pays out over a set number of years regardless of lifespan.

Pro Tip

If you’re using an annuity inside an IRA or 401(k), the tax-deferral benefit is redundant — those accounts already grow tax-deferred. Annuities inside qualified retirement accounts are only worth it if you specifically need the lifetime income guarantee or other contract features, not the tax treatment.

Annuity fees and charges to know

Annuities carry fees that can significantly reduce long-term returns, especially variable products.

Mortality and expense (M&E) fee: An annual charge — typically 1%–1.5% — that compensates the insurer for the lifetime income guarantee.
Surrender charges: Penalties for withdrawing money before the surrender period ends, often 5–10 years, starting at 7%–10% and declining annually.
Administrative fees: Flat or percentage-based annual charges for account maintenance.
Rider fees: Optional add-ons — like guaranteed minimum income benefits — carry their own annual cost, often 0.5%–1.5%.

Tax treatment of annuities

Annuities purchased with after-tax dollars (non-qualified annuities) grow tax-deferred. When you withdraw money, only the earnings portion is taxed as ordinary income — your original contributions come back tax-free.

Annuities held inside a traditional IRA or 401(k) (qualified annuities) are funded with pre-tax dollars, so the entire withdrawal is taxable. Withdrawals before age 59½ trigger a 10% IRS early withdrawal penalty on top of ordinary income tax, the same rule that governs Roth conversions and other retirement account distributions.

Good to know: Annuity death benefits pass directly to named beneficiaries and avoid probate, but they do not receive a step-up in cost basis the way inherited brokerage accounts do. Beneficiaries owe ordinary income tax on any gains distributed from an inherited annuity.

How to buy an annuity

Define your income goal: Decide how much guaranteed monthly income you need and when you need it to start — this determines whether a deferred or immediate annuity fits your timeline.
Choose the annuity type: Match your risk tolerance to the product: fixed for certainty, indexed for balanced growth, variable for market exposure.
Compare insurers by financial strength: Check AM Best or Moody’s ratings — annuity guarantees are only as strong as the insurer backing them.
Get quotes from multiple carriers: Payout rates vary significantly across insurers for identical contracts. Use an independent broker rather than a single-company agent.
Review the surrender period: Avoid locking up money you may need before the surrender period expires. Keep liquid reserves separate from your annuity.
Read the contract before signing: Verify the payout option, any rider terms, and what happens to your money if you die during the accumulation phase.

When an annuity makes sense — and when it doesn’t

Annuities work best when you have a specific gap in guaranteed lifetime income that Social Security and a pension don’t cover. If your fixed expenses in retirement exceed your guaranteed income sources, an income annuity can close that gap reliably.

They make less sense if you have significant liquidity needs, a shorter life expectancy, or already have sufficient guaranteed income from other sources. Retirement planning that relies heavily on annuities at the expense of flexibility can leave you without accessible funds for large, unexpected expenses.

Workers who have access to employer-sponsored plans like a 457 plan or 403(b) should maximize those first — the fees are generally lower and the tax advantages are equivalent.

Annuities vs. other retirement income strategies

Strategy	Income guarantee	Flexibility	Upside potential
Income annuity	Lifetime	Low	None (fixed)
Bond ladder	Fixed period only	Medium	Low
Dividend portfolio	None	High	High
Systematic withdrawal (4% rule)	None	High	High
Pension / Social Security	Lifetime	None	None

Key takeaways

An annuity converts a lump sum into guaranteed income payments, addressing the risk of outliving your savings.
The four main types — fixed, variable, indexed, and immediate — vary by risk level, return structure, and when payments begin.
Surrender charges can trap your money for 5–10 years; always keep a separate liquid emergency fund.
Annuity earnings grow tax-deferred, but withdrawals are taxed as ordinary income — not capital gains.
Compare quotes from multiple insurers and verify AM Best ratings before purchasing; the guarantee is only as strong as the company backing it.
Annuities inside qualified retirement accounts don’t add tax-deferral benefits — evaluate them solely on their income guarantee features.

Frequently asked questions

Is an annuity a good investment for retirement?

An annuity is best described as an insurance product, not an investment. It’s valuable if you need guaranteed lifetime income that Social Security alone doesn’t provide. For pure wealth accumulation, low-cost index funds typically outperform annuities over time.

What happens to an annuity when you die?

It depends on the payout option you chose. A “life only” annuity ends at death with no residual value. A “life with period certain” or “joint and survivor” option continues payments to beneficiaries according to the contract terms.

Can you lose money in an annuity?

In a fixed or immediate annuity, your principal is protected. In a variable annuity, your account value can decline if the underlying investment subaccounts lose value. Fixed indexed annuities typically protect your principal from market losses but cap your gains.

What is the difference between a deferred and an immediate annuity?

A deferred annuity accumulates value over time before payments begin — sometimes decades later. An immediate annuity starts payments within 30 days of purchase and is typically funded with a single lump sum.

Are annuity payments taxable?

Partially. For non-qualified annuities (funded with after-tax money), only the earnings portion of each payment is taxable. For qualified annuities held inside an IRA, the full payment is taxable as ordinary income.
