What an annuity is and how the basic exchange works

An annuity is a contract between you and an insurance company. You give the company a lump sum of money (or make payments over time), and in return, the company promises to pay you a stream of income — usually for the rest of your life, or for a set number of years. The insurance company invests your money and uses the returns, along with what other customers pay in, to fund those payments back to you.

The core idea is straightforward: you trade a large amount of money today for smaller, predictable payments later. The insurance company bets that you will live longer than average (so they pay out more than your initial deposit), and you bet that you will live long enough to get back more than you put in. If you live a very long time, you win. If you die early, your heirs may get less than you paid in — though some annuity types protect against this.

Annuities are not investments you buy through a brokerage. They are insurance products sold by insurance companies, insurance agents, and some financial advisors. The payments you receive are partly a return of your own money and partly earnings on what the company invested.

Key Takeaways

  • You pay an insurance company a sum of money, and they pay you regular income for life or a fixed period in return.
  • The amount of each payment depends on your age, gender, how much you paid in, and what type of annuity you choose.
  • Fixed annuities pay the same amount every period; variable annuities pay amounts that change based on investment performance.
  • Once you start receiving payments, you cannot usually get your remaining balance back as a lump sum.
  • Annuities carry fees, surrender charges if you withdraw early, and tax consequences that vary by account type.

The three main types: fixed, variable, and indexed

A fixed annuity pays you the same dollar amount every month or year for life (or your chosen period). The insurance company guarantees this payment and bears the investment risk. If you buy a fixed annuity at age 65 with $200,000, the company might promise you $1,000 per month for life. That $1,000 does not change, even if inflation rises or interest rates fall. Your payment is locked in.

A variable annuity ties your payments to the performance of investment accounts you choose — usually mutual funds. If those investments do well, your payment goes up. If they do poorly, your payment goes down. You bear the investment risk, not the insurance company. Variable annuities often come with a may provide minimum payment (called a "death benefit" or "income may provide"), but the actual payment fluctuates.

An indexed annuity (also called an equity-indexed annuity) sits between the two. Your payment is tied to the performance of a stock market index — often the S&P 500 — but with a floor and a ceiling. You might earn 50% to 80% of whatever the index gains, but your payment will not fall below a may provide minimum (often 0% to 2% annually). This limits both your upside and your downside.

When payments start and how long they last

An when ready annuity is one you buy with a lump sum, and payments begin within a few months — often within 30 to 90 days. You hand over the money, and the income starts right away. This type is common for people who have just retired or received a large settlement and want to convert it into steady income.

A deferred annuity is one you buy now but do not take payments from until later — sometimes years or decades later. You might buy a deferred annuity at age 50 and not start taking income until age 70. During the waiting period, your money grows (either at a fixed rate or based on investments). Deferred annuities are often used as a retirement savings tool.

Once you start receiving payments, you choose how long they last. A life annuity pays you for as long as you live, no matter how long that is. A period-certain annuity pays for a fixed number of years (10, 20, 30 years) and then stops. A joint-and-survivor annuity continues paying your spouse or beneficiary after you die. Each choice changes the size of your monthly payment — a life annuity pays less per month than a 10-year annuity, because the company might have to pay for 30+ years instead of 10.

How the insurance company calculates your payment amount

The insurance company uses several factors to decide how much to pay you each month. Your age at purchase is the biggest one: the older you are, the higher your monthly payment, because statistically you will receive payments for fewer years. A 75-year-old gets a larger monthly check than a 65-year-old who paid in the same amount.

Your gender also matters (in most states). Women typically receive lower monthly payments than men at the same age, because women have longer average life expectancy. Some states have banned this practice, so the rules vary by location.

The amount you pay in is straightforward: more money in means more money out each month. The type of annuity (life, period-certain, joint-survivor) also changes the calculation. A joint-survivor annuity pays less per month than a life annuity, because the company expects to pay longer.

For fixed annuities, interest rates at the time of purchase matter greatly. When rates are high, the company can earn more on your money, so they pay you more. When rates are low, they pay you less. This is why people often rush to buy fixed annuities when interest rates rise.

Fees, surrender charges, and what they cost you

Annuities are not free to own. A surrender charge is a penalty if you withdraw money or cancel the annuity within a set period — often 5 to 10 years. If you buy a $100,000 annuity with a 7-year surrender period and try to withdraw $20,000 in year 3, you might owe 6% of that withdrawal as a penalty ($1,200). The surrender charge typically decreases each year you hold the annuity.

Variable annuities charge mortality and expense (M&E) fees, usually 0.5% to 1.5% per year of your account balance. These cover the insurance company's costs and the may provide they provide. You also pay the fees of the underlying mutual funds you choose, which can range from 0.1% to 2% or more per year. Together, these can add up to 1% to 3% annually.

Fixed annuities typically have lower visible fees, but the insurance company builds their profit into the rate they offer you. An indexed annuity might charge an annual fee of 0.5% to 1%, plus they keep a portion of the index gains (called a "spread" or "margin").

Some annuities come with riders — optional add-ons that cost extra but provide additional protection. A long-term care rider, for example, might let you access more of your money if you need nursing home care. These riders can cost 0.5% to 1% per year.

Tax treatment and where annuities fit in retirement accounts

If you buy an annuity with money that has already been taxed (outside a retirement account), the tax treatment is split. Each payment you receive is partly a return of your own money (not taxed) and partly earnings (taxed as ordinary income). The insurance company calculates an "exclusion ratio" to show you how much of each payment is tax-free.

If you buy an annuity inside an IRA or 401(k), the entire payment is taxed as ordinary income when you receive it. The money went in tax-deferred, so it comes out taxed. If you withdraw money before age 59½ from an annuity in a retirement account, you may owe a 10% early withdrawal penalty on top of income tax.

Annuities inside retirement accounts are sometimes redundant, because the account itself already provides tax deferral. Many financial advisors recommend buying annuities with after-tax money instead. However, some people use annuities inside IRAs to lock in a may provide income stream.

What happens to your money if you die

This depends on the type of annuity you chose. If you bought a life annuity with no survivor benefit, payments stop when you die, and your heirs receive nothing. The remaining balance stays with the insurance company. This is the trade-off for the highest monthly payment.

If you chose a period-certain annuity (say, 20 years), and you die in year 12, your beneficiary continues to receive payments for the remaining 8 years. Once the 20-year period ends, payments stop.

A joint-and-survivor annuity continues paying your spouse or named beneficiary after you die, usually at a reduced rate (often 50% to 100% of what you were receiving). This option costs you a lower monthly payment while you are alive, but it protects your survivor.

Some annuities include a death benefit that guarantees your heirs will receive at least what you paid in, even if you die early. This protection increases the cost of the annuity and reduces your monthly payment.

Common reasons people buy annuities and common pitfalls

People buy annuities mainly to convert a large sum into may provide lifetime income. If you have $300,000 and worry about running out of money in retirement, an when ready annuity can turn that into a predictable monthly check for life. This removes the risk that you will outlive your savings.

Annuities are also used as a hedge against longevity risk — the risk of living much longer than expected. If your family has a history of long life, an annuity can protect you against that scenario.

A common pitfall is buying an annuity without understanding the surrender charges. People sometimes buy an annuity, then need access to their money a few years later and face steep penalties. Another pitfall is buying a variable annuity with high fees without realizing how much those fees will reduce your returns over time.

Some people buy annuities from aggressive sales pitches without comparing options or understanding what they are giving up. Once you start receiving payments from most annuities, you cannot reverse the decision. It is permanent. Taking time to understand what you are buying, and getting a second opinion, is worth the effort.

Frequently Asked Questions

Can I get my money back if I change my mind?

Once you start receiving payments from an annuity, you cannot usually reverse it or get a lump sum of your remaining balance. Before you start payments, you can usually cancel within a "free look" period (typically 10 to 30 days) and get your money back. After that, surrender charges explore if you withdraw early. Read the contract carefully before you buy.

Is an annuity the same as a pension?

Both provide regular income for life, but they work differently. A pension is a benefit your employer provides and funds; you do not buy it. An annuity is a contract you buy from an insurance company with your own money. Some people use an annuity to mimic a pension by converting a lump sum into lifetime income.

What if interest rates rise after I buy a fixed annuity?

Your payment stays the same — that is the point of a fixed annuity. However, if you try to sell the annuity to someone else, they will pay less for it, because new annuities at higher rates are now more attractive. You are locked into your original rate for life.

Do I have to buy an annuity with my entire retirement savings?

No. Many people buy a partial annuity — enough to cover essential expenses like housing and food — and invest the rest. This gives you both may provide income and flexibility. There is no rule about how much to annuitize.

What is the difference between an annuity and a life insurance policy?

Life insurance pays your beneficiaries a lump sum when you die. An annuity pays you regular income while you are alive. They serve opposite purposes: insurance protects your family if you die young; an annuity protects you if you live a long time.
