The primary reason for buying an annuity is to create a stream of income you cannot outlive. An annuity is a contract with an insurance company: you hand over money now, and in return the insurer promises to pay you regularly later, potentially for the rest of your life. That guarantee answers the central anxiety of retirement planning, which is running out of money before you run out of years.
Everything else an annuity offers (tax-deferred growth, protection from market losses, a death benefit for a beneficiary) is secondary. Those features matter, and for some buyers they tip the decision, but they exist alongside the main product rather than replacing it. The main product is lifetime income.
How the Lifetime Income Guarantee Works
When you’re ready to start collecting, the insurance company converts your account balance into a series of payments through a process called annuitization. The insurer uses actuarial tables that factor in your age and life expectancy to calculate the payment amount. If you live to 100, the checks keep coming. If you die earlier than expected, the insurer keeps what remains, unless you chose a payout option that protects against that outcome.
The result works like a personal pension. You receive a predictable amount on a set schedule, which makes budgeting for housing, food, and utilities straightforward. You’re not hoping the market cooperates or trying to figure out a safe withdrawal rate from a portfolio. The insurance company has taken on the risk of you living longer than average, and it pools that risk across thousands of other contract holders to make the math work.
Most contracts offer several payout structures:
- A life-only option pays the highest monthly amount but stops entirely when you die.
- A period-certain option guarantees payments for a fixed number of years, so if you die within that window a beneficiary collects the rest.
- A joint-and-survivor option covers two people and continues as long as either is alive, though the monthly amount is typically lower.
Choosing among them depends on whether your goal is to maximize your own income or protect a spouse or dependent.
Immediate vs. Deferred, and the Types in Between
Annuities fall into two broad timing categories. An immediate annuity starts paying income within about a year of your lump-sum purchase. A deferred annuity lets your money grow over time before you begin withdrawals, splitting the contract into an accumulation phase and a later payout phase.1Investor.gov. Annuities
Within the deferred category, the main types differ by how your money grows and how much risk you bear. Fixed annuities guarantee a minimum interest rate; your principal is safe but returns are modest. Variable annuities let you choose from a menu of mutual fund-like investment options, so returns depend entirely on fund performance and you can lose money. Fixed-indexed annuities link returns to a market index but prevent your account value from dropping in a down year, in exchange for a cap on your upside.1Investor.gov. Annuities
Tax-Deferred Growth
Money inside an annuity grows without triggering an annual tax bill. Under federal law, you don’t owe income or capital gains taxes on interest, dividends, or investment gains while they sit inside the contract.2Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts The money that would have gone to taxes stays invested and generates its own returns. Over two or three decades, the difference can be substantial compared to a regular taxable brokerage account where you settle up with the IRS every year.
The tax bill doesn’t disappear. It gets pushed to the point where you start taking money out. If your income drops in retirement and you land in a lower tax bracket, the delayed taxes cost less than they would have during your peak earning years. For high earners who expect to remain in a high bracket, the deferral advantage shrinks.
Protection From Market Losses
Fixed and fixed-indexed annuities offer something you can’t get from a stock portfolio: a contractual floor that prevents your account value from dropping in a bad year. With a fixed annuity, the insurer guarantees a stated rate and your balance grows by that rate. With a fixed-indexed annuity, the credited interest is linked to the performance of a market index like the S&P 500, but your account is protected from negative returns. If the index falls 20 percent in a year, your account stays flat rather than losing money.
That protection comes with limits on the upside. Insurers use rate caps, participation rates, or spreads to constrain what you actually earn in a good year, and those limits can be adjusted over time. The marketing emphasizes “no losses,” which is true, but the fine print on the upside determines whether the product keeps pace with inflation over the long run.
Variable annuities do not provide this downside protection. Your money is invested in subaccounts that function like mutual funds, and the value rises and falls with the market. Some variable annuities offer optional guaranteed living benefit riders for an additional annual fee, but the base contract carries full investment risk.1Investor.gov. Annuities
A Death Benefit for a Beneficiary
Most annuity contracts include a death benefit that pays the remaining value to a named beneficiary if you die before the account is fully distributed. The payout can be structured as a lump sum or as continued income payments. Because the annuity is a private contract with a designated beneficiary, the proceeds typically pass directly to that person without going through probate, similar to life insurance. The exception is when no beneficiary is named, the named beneficiary has already died with no contingent listed, or the estate itself is designated as the recipient.
The death benefit is not tax-free. Any growth above the original premiums is taxable to the beneficiary as ordinary income.3Internal Revenue Service. Publication 575, Pension and Annuity Income If the original owner paid $100,000 in premiums and the account grew to $160,000, the beneficiary owes income tax on the $60,000 of gain. A lump sum gets taxed in a single year, which can push the beneficiary into a higher bracket. Spreading the payout over time softens the hit. Unlike inherited stocks or real estate, annuity gains do not receive a stepped-up cost basis at death.
The Trade-Offs That Shape Whether It Fits
Annuities buy certainty, and certainty is not free. Before deciding the primary reason is reason enough, weigh what you give up.
Fees. Annuities are not cheap to own. Variable annuities tend to be the most expensive, with a mortality and expense risk charge of roughly 1.25 percent of account value per year,4Investor.gov. Updated Investor Bulletin: Variable Annuities administrative fees around 0.15 percent or a flat $25 to $50,5SEC. Variable Annuities: What You Should Know and underlying fund expenses on top. Stacked together, total annual charges commonly land between 1.25 percent and 2 percent before any optional rider fees. Fixed and fixed-indexed annuities carry lower explicit fees because the insurer builds its costs into the crediting formula.
Lock-up periods. Most annuities impose a surrender charge if you pull money out during the first several years. The surrender period typically runs six to ten years from each premium payment, and the charge decreases annually until it reaches zero.6Investor.gov. Surrender Charge A common schedule starts at 7 percent in year one and drops by a point each year.5SEC. Variable Annuities: What You Should Know Many contracts allow penalty-free withdrawals of up to 10 percent of your account value annually; anything beyond that triggers the charge.
Early withdrawal penalty. If you take money out before age 59½, the IRS adds a 10 percent penalty on top of regular income tax, applied to the taxable portion of the withdrawal.2Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Narrow exceptions exist for death, disability, or a series of substantially equal payments over your life expectancy. Treat money you put into an annuity as committed for the long haul.
Ordinary income rates on payments. When you start receiving annuity payments, the taxable portion is treated as ordinary income, not capital gains. You don’t get the preferential long-term capital gains rate on gains that come out of an annuity. If you bought the contract with after-tax money, part of each payment is a tax-free return of premium under an exclusion ratio set by the IRS; once you’ve recovered your entire investment, every subsequent payment is fully taxable.3Internal Revenue Service. Publication 575, Pension and Annuity Income
Insurer risk. An annuity is only as good as the insurer’s ability to pay. Unlike a bank deposit protected by the FDIC, annuities are backed by the financial strength of the issuing company. If the insurer becomes insolvent, your protection comes from your state’s life and health insurance guaranty association. Under the model most states follow, the coverage limit is $250,000 in present value of annuity benefits per person.7NOLHGA. FAQs: Product Coverage Some states set the cap higher or lower, and most impose an aggregate limit across all lines of insurance with the same failed company.8NAIC. Life and Health Guaranty Fund Laws Checking an insurer’s financial strength ratings from A.M. Best, Moody’s, or S&P before buying is the first line of defense; the guaranty association is a backstop, not a substitute for picking a sound company. For large purchases, splitting the money between two highly rated insurers keeps each contract within your state’s protection threshold.
If longevity risk is what keeps you up at night, an annuity is the one financial product built specifically to solve it. If liquidity, flexibility, or minimizing fees matters more, the same features that make the income guarantee possible will work against you.
