Different Types Of Annuities And How They Are Named

Key Takeaways

• An annuity is a contract with an insurer that pays you income, now or later.
• Fixed annuities pay a guaranteed rate; variable annuities rise and fall with investments; indexed annuities sit in between.
• Immediate annuities start paying right away; deferred annuities grow first, then pay later.
• The right type depends on whether you want certainty, growth, or income timing.

What is an annuity?

An annuity^[1] is a contract between you and an insurance company. You hand over money, either as a single lump sum or through a series of payments, and in return the insurer promises to pay you income, either starting right away or at some point in the future. At its heart, an annuity is a tool for converting savings into a dependable stream of income, which is why it's most often used for retirement.

Annuities have grown more important as traditional pensions have faded. For previous generations, an employer pension provided guaranteed lifetime income; today most workers must build that security themselves, often starting with a retirement projection. An annuity can fill that gap, offering payments that last as long as you live and protecting against the risk of outliving your savings: a guarantee that ordinary investment accounts can't make.

Most annuities have two phases. During the accumulation phase, your money grows, usually tax-deferred. During the payout (or annuitization) phase, the insurer converts the balance into income. The many 'types' of annuities are really different answers to two questions: how your money grows during accumulation (fixed, variable, or indexed) and when the income begins (immediate or deferred). The sections below take each in turn. You can estimate an annuity's payout with the Annuity Calculator.

Fixed annuities

A fixed annuity is the simplest and most conservative type. The insurer pays a guaranteed interest rate for a set period, and your balance grows tax-deferred, much like a bank CD, but issued by an insurance company rather than a bank. You know exactly what you'll earn, which makes a fixed annuity attractive to people who prioritize certainty over growth.

The trade-off for that guarantee is a relatively modest return. Because the insurer bears the investment risk, the rate it offers tends to be conservative, broadly comparable to other safe, fixed-income options. In exchange you get predictability: no market exposure, no surprises, and a known value at the end of the term. For retirees who can't afford to lose principal, that reliability is often worth the lower yield.

Fixed annuities are also the easiest type to compare and shop, since the guaranteed rate is the headline number. They're frequently weighed against bank CDs, and the deciding factor is usually the tax treatment: annuity growth is tax-deferred while CD interest is taxed yearly. Our guide comparing fixed annuities and CDs works through that decision in detail. One more wrinkle worth knowing: many fixed annuities offer a multi-year guarantee (a MYGA) that locks the rate for a set number of years, so you can match the term to your time horizon much as you would with a CD.

Variable annuities

A variable annuity^[2] invests your money in a menu of sub-accounts that work much like mutual funds, holding stocks, bonds, or a mix. Your account value, and the income it eventually produces, rises and falls with the performance of those investments. The appeal is growth: over a long horizon, the market exposure offers more upside than a fixed annuity's guaranteed rate can provide.

That upside comes with real downside. Because your balance is tied to the markets, a downturn can reduce its value, and unlike a fixed annuity there's no guaranteed floor on the growth. Variable annuities also tend to carry the highest fees of any type: mortality and expense charges, administrative fees, fund expenses, and charges for any optional guarantees. Those costs can quietly consume a meaningful slice of your returns.

Many variable annuities offer optional riders, such as a guaranteed minimum income or death benefit, that add a layer of protection, for an added cost. These features can be valuable, but they make the product more complex and more expensive, so it's essential to read the fee schedule closely and only pay for guarantees you'll actually use. A variable annuity suits someone comfortable with market risk who still wants the option of lifetime income.

Indexed annuities

An indexed annuity, sometimes called a fixed-indexed annuity, tries to split the difference between fixed and variable products. Your return is tied to the performance of a market index such as the S&P 500, but with two key limits: a cap that sets the maximum you can earn in a period, and a floor (usually zero) that protects you from losses. You get some of the market's upside without its full downside.

The catch is complexity. The amount you actually earn is shaped by several moving parts: the cap, the participation rate (the percentage of the index's gain you receive), and sometimes a spread subtracted from returns. For example, if the index rises 10% but your cap is 6%, you earn 6%; if it rises 4% with an 80% participation rate, you earn 3.2%. These terms vary widely between products and are easy to misjudge.

Because of that complexity, indexed annuities are among the most over-sold and misunderstood financial products. The 'market upside with no downside' pitch oversimplifies how caps and participation rates limit your gains in strong years. They can be a reasonable choice for cautious investors who want more than a fixed rate, but only after you fully understand how the crediting formula works, not just the headline.

Immediate vs. deferred annuities

Beyond how your money grows, annuities differ in when the income starts. An immediate annuity (often called a single-premium immediate annuity) converts a lump sum into income that begins almost right away, typically within a year. It's the classic tool for someone at retirement who wants to turn a portion of their savings into a guaranteed paycheck immediately, without managing investments.

A deferred annuity, by contrast, has an accumulation phase: your money grows tax-deferred for years, even decades, before the payout phase begins. This suits people who are still working and building savings, and who want tax-deferred growth now with the option of guaranteed income later. The longer accumulation period gives compounding more time to work before income starts.

Importantly, immediate and deferred describe timing, not the growth type, so they combine with the categories above. A deferred annuity can be fixed, variable, or indexed during its accumulation phase, and an immediate annuity is usually fixed. Matching the timing to your stage of life is half the decision: deferred while you're accumulating, immediate when you're ready to draw income. A related variation is the deferred income annuity, which you buy now to begin paying at a chosen future date: a way to guarantee income for later years while leaving the rest of your savings invested in the meantime.

Choosing the right annuity

The right annuity follows directly from your goal. If certainty matters most, a fixed annuity delivers a guaranteed rate. If you want growth potential and can tolerate risk, a variable annuity offers market exposure, while an indexed annuity provides a cautious middle ground. On timing, choose immediate if you need income now and deferred if you're still building toward retirement.

Whatever the type, the fine print matters as much as the headline. Fees, surrender charges, and the insurer's financial strength vary enormously between products and can make or break the value. An annuity is also a long-term, relatively illiquid commitment, so it should be one piece of a broader plan rather than a home for money you may need soon. Because the products are complex, it's wise to compare several and read the contract carefully, or consult a fee-only advisor with no incentive to push a particular product.

A few mistakes come up again and again when people shop for annuities:

• Ignoring fees: variable and indexed annuities can carry layers of cost that erode returns.
• Misjudging indexed caps: the advertised 'market upside' is limited by caps and participation rates.
• Overlooking surrender charges: early withdrawals can be costly for years after purchase.
• Buying more guarantees than you need: optional riders add cost; only pay for ones you'll use.
• Overlooking the insurer's rating: the guarantee is only as strong as the company behind it.

Frequently Asked Questions

Which type of annuity is safest?

Fixed annuities are the most predictable, paying a guaranteed rate with no market exposure. Variable annuities carry investment risk, while indexed annuities limit losses but cap gains.

Are annuities a good investment?

They can provide valuable guaranteed income, especially in retirement, but they're less liquid and often carry fees. They work best as one piece of a broader plan, not a substitute for it.

What's the difference between immediate and deferred annuities?

An immediate annuity starts paying income almost right away; a deferred annuity grows tax-deferred for years before payments begin. The choice depends on when you need income.

How are indexed annuities different from variable annuities?

An indexed annuity ties returns to an index with a cap and a floor, limiting both gains and losses. A variable annuity invests directly in sub-accounts, so it has more upside but also real downside risk.

What fees do annuities charge?

Fixed annuities have minimal explicit fees, while variable and indexed annuities can carry mortality and expense charges, fund fees, rider costs, and surrender charges. Always read the fee schedule.
