What Is an Annuity and Should You Get One?

Few financial products are more misunderstood — or more aggressively sold — than annuities. Ask ten people what an annuity is and you'll get ten different answers. Ask financial advisors and you'll get two camps: those who swear by them and those who actively warn against them.

The truth is somewhere in the middle. Annuities aren't inherently good or bad. They're a specific tool that makes sense in specific situations — and is poorly suited to others. Here's what you actually need to know.

What Is an Annuity?

An annuity is a contract between you and an insurance company. You give the insurer a lump sum of money (or a series of payments), and in exchange, the insurer agrees to pay you a regular income — either immediately or at some point in the future — for a specified period or for the rest of your life.

At its core, an annuity is insurance against outliving your money. That's the fundamental value proposition: guaranteed income that can't run out regardless of how long you live.

The mechanics vary significantly by type, but that's the basic concept.

Immediate vs. deferred:

• Immediate annuity: You pay a lump sum now and start receiving monthly payments almost immediately (usually within 30 days to a year). Best for people already in or near retirement who want to convert savings into income.
• Deferred annuity: You invest money now and payments begin at a future date. The money grows in the interim. Best for people still accumulating retirement savings who want guaranteed future income.

The Main Types of Annuities

Fixed annuity: The insurance company guarantees a specific interest rate on your money during the accumulation phase, and a specific payment amount during the payout phase. Predictable, straightforward, and conservative. Similar concept to a CD, but offered by an insurer. Best for people who want certainty above all else and can tolerate modest returns.

Variable annuity: Your money is invested in sub-accounts that function like mutual funds. Returns — and therefore your future payment amounts — vary based on market performance. Higher potential upside than fixed annuities, but also real downside risk. Fees are typically higher. Variable annuities are often criticized for complexity and cost.

Fixed-indexed annuity: A hybrid. Your returns are tied to a market index (like the S&P 500), but your principal is protected from market losses. You capture some upside when markets rise and avoid losses when markets fall. The trade-off: your upside is capped (participation rates and caps limit how much of the index gain you actually receive). Popular because of the "no loss" protection, but the fee structures can be complex.

Income annuity (SPIA or DIA): Single Premium Immediate Annuity (SPIA) and Deferred Income Annuity (DIA) are designed purely to create guaranteed income. You hand over a lump sum and receive income for life (or a set period). No accumulation bells and whistles — just pure income insurance. Often the cleanest and most cost-effective annuity option.

The Pros of Annuities

Guaranteed income you can't outlive. If you choose a lifetime payout option, the insurer pays you as long as you live — even if that's 40 years after you bought the annuity. This eliminates longevity risk, which is the risk that you outlive your savings. For someone genuinely worried about running out of money, this guarantee has real value.

Tax-deferred growth. Money inside a deferred annuity grows tax-deferred, meaning you don't pay taxes on the growth until you withdraw it. This is similar to a traditional IRA.

Predictable income for budgeting. Knowing exactly how much money will arrive each month regardless of market conditions makes retirement budgeting significantly easier. Some retirees find this peace of mind valuable even if the math doesn't favor annuities over other strategies.

Protection from market volatility (for fixed options). Fixed and fixed-indexed annuities don't decline in value when markets drop. For retirees who can't emotionally or financially withstand a 30% portfolio drop right after retirement, this protection has genuine value.

The Cons of Annuities

High fees. Variable annuities in particular carry layers of fees: mortality and expense risk charges (M&E fees), administrative fees, sub-account investment fees, and optional rider fees. Total annual costs of 2–3% are common — and that's a significant drag on returns over time.

Surrender charges. Most annuities lock up your money for a surrender period, typically 5–10 years. If you need to withdraw more than the allowed amount (usually 10% per year) during this period, you'll pay surrender charges that can be 7–8% of your withdrawal. This illiquidity is a serious drawback if your financial situation changes.

Complexity. Many annuities are genuinely difficult to understand — which benefits the seller more than the buyer. If you can't clearly explain the product you own, you likely don't fully understand what you bought.

Commissions create conflicts of interest. Annuities often pay salespeople 4–8% commissions. This creates pressure to sell them regardless of whether they're appropriate for the buyer. Many people buy annuities not because they're the best tool for their situation, but because a commissioned advisor recommended them.

Lower potential returns. Compared to a simple low-cost index fund portfolio, most annuities underperform over the long run — particularly after fees and the cost of the income guarantee.

When an Annuity Actually Makes Sense

Despite the criticisms, there are situations where an annuity is a genuinely smart choice:

You're worried about outliving your money. If you have no pension, moderate savings, and real anxiety about running out of money in your 80s or 90s, converting a portion of savings into a lifetime income annuity may be worth the cost of the guarantee.

You want to cover fixed expenses with guaranteed income. Social Security may not fully cover your essential monthly expenses. An annuity that bridges that gap — covering rent, utilities, food, and insurance — lets you invest the rest of your savings more aggressively, because you know the basics are covered.

You're risk-averse and would otherwise hold too much cash. Some retirees hold excessive cash because they're afraid to invest. An annuity can be preferable to holding 40% in cash earning next to nothing while being too conservative to benefit from market growth.

A simple income annuity with no riders. If you're going to buy an annuity, a straightforward Single Premium Immediate Annuity (SPIA) from a highly-rated insurer is usually the cleanest option. Low fees, clear terms, and a simple value proposition: you give them money, they send you a check every month for life.

Questions to Ask Before Buying

If you're considering an annuity, get clear answers to these questions:

• What is the total annual cost, including all fees and rider charges?
• What is the surrender period and what are the surrender charges?
• What is the insurer's financial strength rating (look for A-rated or better from AM Best or Standard & Poor's)?
• What is the payout rate, and how does it compare to what I could generate from a bond ladder or a dividend portfolio?
• What happens to remaining money in the annuity when I die? (Options range from heirs receiving nothing to a death benefit — each has trade-offs.)
• Is the advisor selling this annuity a fiduciary? (If not, they are not required to act in your best interest.)

An annuity can be a legitimate component of a retirement income plan. It can also be an expensive, illiquid, unnecessary product pushed by a commissioned salesperson. The difference often comes down to understanding exactly what you're buying and why.
