Planning for retirement can be stressful, especially when you worry about running out of money. The 2025 Goldman Sachs Retirement Survey found that 58% of working Americans are concerned about outliving their savings. As traditional pensions become less common, private annuities are now a main way to protect against the risk of outliving your money. So, what is an annuity? Simply put, it is a contract between you and a life insurance company that helps you build up savings and later turn them into steady income. Annuities can help secure your finances, but they are also complex, come with high sales fees, and are closely regulated. Let’s look at how they work, the different types, and the important details so you can see if an annuity fits your retirement plan.
The Two Core Phases of an Annuity
An annuity contract usually has two main phases. The first is the Accumulation Phase, when your money grows. For non-qualified contracts, which use after-tax dollars, your earnings grow without being taxed each year.
After the accumulation phase, the Annuitization or Distribution Phase starts. At this point, you turn your savings into a steady, guaranteed income, such as with a single-life immediate annuity, to help pay for your retirement. 
Timing Options: Immediate vs. Deferred
Depending on your personal timeline, you can choose exactly when those payouts start. An Immediate Annuity (a contract that starts income payments soon after a lump-sum deposit) begins paying out regular income right away, usually within a year of purchase. Conversely, a Deferred Annuity (a contract that delays payments until a chosen future date) gives your principal more time to compound (grow from earning returns) during the accumulation phase.
The Main Flavors: Fixed, Variable, and Indexed
Annuities are mainly grouped by how they credit interest, which affects how your money grows. Picking the right type means weighing guaranteed safety, growth potential, and costs.
Fixed Annuities: How it grows: The insurer guarantees a flat, contractually specified interest rate (a set rate for your returns) for a set period.
Risk Profile: There is zero market risk (your money is not invested in stocks or bonds that fluctuate), as the contract is fully backed by the insurer’s general account (the pooled assets of the insurance company).
The downside: Your growth potential is limited, and payments usually do not adjust for inflation. Over time, this can reduce your buying power.
Variable Annuities
How it grows: Your returns depend on how the underlying investment portfolios perform. These work much like mutual funds.
Risk Profile: There is high market risk. The value of your investment changes with the market, so your principal can go up or down.
The downside: These annuities have high internal fees, such as administrative and other charges, which can reduce your overall returns.
Fixed-Indexed (Hybrid) Annuities
How it grows: Your growth is tied to a stock market index, like the S&P 500, which tracks large U.S. companies.
Risk Profile: There is no risk of losing money if the market drops. The contract guarantees you will not earn less than 0%, so your principal stays safe during downturns.
The downside: Your growth is limited by caps, participation rates, and fees. This means you will not get the full benefit if the stock market does very well.

The Strategic Benefits: Why Savers Choose Annuities
When used as part of a complete plan, annuities offer some benefits that regular stock and bond portfolios cannot provide:
Guaranteed Lifetime Income: Annuities are the only financial product that can legally promise you steady income for life. By sharing the risk among many people, insurers can often pay out more than the usual safe withdrawal rates from regular investments.
Tax-Deferred Growth: Your earnings grow without being taxed each year during the accumulation phase. This lets you earn interest on your principal, on your interest, and on money you would have paid in taxes.
No Contribution Limits: Unlike IRAs or 401(k)s, which have yearly limits, non-qualified annuities let you invest large amounts of after-tax money and grow it tax-deferred.
The Systemic Drawbacks and Fine Print
Although annuity ads focus on safety and guarantees, these products often come with high costs and rules that can limit your flexibility:
High Fees & Commissions: Annuities, especially variable ones, often have many internal fees. These can include risk charges, administrative costs, management fees, and extra rider fees, adding up to 2% to 3% per year. High agent commissions can also lead to strict policy rules.
Severe Surrender Charges: Annuities are not easy to turn into cash and are meant for the long term. If you take out more than the allowed amount each year, usually about 10% of your account, you will pay high penalties for early withdrawal.
Suboptimal Tax Treatment & IRS Penalties: While your money grows tax-deferred, when you take it out, gains are taxed as regular income, not at the lower capital gains rate. If you withdraw money before age 59½, you also face a 10% IRS penalty plus regular taxes.
No FDIC Insurance: Annuities are not insured by the federal government or the FDIC. Your payouts depend on the financial strength of the insurance company. Always check independent credit ratings; a high rating from AM Best, like A- or better, shows the company is likely to keep its promises over the long term.
Due Diligence: 3 Questions to Ask Yourself Before Buying
You should not buy an annuity on its own. It needs to be part of your overall retirement plan. To see if an annuity is right for you, consider these three questions:
- How long until you retire? If retirement is many years away, a deferred annuity gives your money more time to grow tax-deferred. If you are retiring soon, an immediate annuity may help cover your basic living costs.
- Do you need guaranteed income now, or do you want to grow your wealth for later? Figure out your income gap by subtracting your steady income sources, like Social Security and pensions, from your monthly expenses. If you have a shortfall, an income annuity can help. If your basic costs are covered, you might prefer to keep your money in more flexible, higher-growth investments.
- How much risk can you handle? If you worry about market ups and downs, a fixed or fixed-indexed annuity keeps your principal safe. If you are comfortable with market changes for the chance of higher returns, a variable annuity could be an option, as long as you understand the fees.
