How an Annuity Works: What Happens to Your Money

An annuity converts a lump sum or regular payments into may provide income for life or a set period

An annuity is a contract between you and an insurance company. You give the company money—either all at once or over time—and in return, the company promises to pay you a stream of income later. The insurance company invests your money, keeps some of the returns, and sends the rest to you on a schedule you choose: monthly, quarterly, annually, or in a lump sum. The amount you receive each payment depends on how much you put in, your age, how long you want payments to last, and current interest rates when you buy the annuity.

The core appeal is predictability. Unlike a savings account or investment portfolio, an annuity removes the risk that you will run out of money or that market downturns will shrink your income. The insurance company bears that risk instead. In exchange, you give up access to the full amount you invested and accept that inflation will reduce what each payment buys over time.

Key Takeaways

• You pay money to an insurance company now, and they pay you income later on a schedule you choose—monthly, quarterly, or annually.
• The insurance company invests your money and keeps some returns; you receive the rest as may provide payments.
• when ready annuities begin payments within a year of purchase; deferred annuities delay payments until a future date you set.
• Fixed annuities pay the same amount every period; variable annuities tie payments to investment performance and carry more risk.
• Once you buy an annuity, you cannot easily get your money back, so annuities work best for money you know you will not need for other purposes.

The two main types: when ready and deferred

An when ready annuity starts paying you within one year of purchase. You give the insurance company a lump sum—often from a pension payout, inheritance, or retirement savings—and within 12 months, regular payments begin. This type is straightforward: you know the payment amount upfront, and the insurance company starts sending money right away. when ready annuities are common for people who have just retired and want to convert savings into monthly income.

A deferred annuity delays payments until a future date you choose. You might buy one at age 50 and tell the insurance company to begin payments at age 70. During the waiting period, your money grows—either at a fixed rate or tied to market performance, depending on the type. Deferred annuities appeal to people who do not need income when ready but want to lock in a may provide payment amount years in advance. They also allow your money to compound longer before withdrawals begin.

Fixed annuities pay the same amount every period

A fixed annuity pays you a set dollar amount on every payment date. The insurance company calculates this amount based on your age, the amount you invested, how long you want payments to last, and the interest rate environment when you purchase the contract. Once the contract is signed, that payment amount does not change—you receive the same $1,500 per month, for example, for the rest of your life or for the term you selected.

The trade-off is that inflation erodes the purchasing power of fixed payments over time. A payment that feels adequate at age 65 may feel small at age 85 if prices have risen significantly. Fixed annuities shift investment risk to the insurance company—they must earn enough on your money to cover the promised payments—but they shift inflation risk to you. This type suits people who prioritize certainty and can tolerate the fact that each payment will buy less as years pass.

Variable annuities tie payments to investment performance

A variable annuity ties your payment amount to the performance of investments you choose—typically mutual funds or similar portfolios. You select how your money is invested, and your payment amount rises or falls based on how those investments perform. If your chosen investments earn strong returns, your payments increase. If they decline, your payments decrease. Some variable annuities include a may provide minimum payment, so your income never falls below a floor amount, but the base payment can fluctuate.

Variable annuities carry more risk than fixed annuities because investment performance is uncertain. However, they offer the potential for payments to grow with inflation if your investments perform well. They also typically cost more—variable annuities charge ongoing fees for investment management and insurance features. This type suits people who are comfortable with market risk and want the possibility of higher payments if investments do well, but who also want some income protection if markets decline.

How the insurance company calculates your payment amount

The insurance company uses several factors to determine what you will receive each period. Your age at purchase matters significantly: the older you are, the higher your monthly payment, because the company expects to pay you for fewer years. A 70-year-old buying an when ready annuity receives more per month than a 60-year-old who invests the same amount, because statistically the 70-year-old has fewer years of life remaining.

The amount you invest is straightforward: more money in means more money out. The payment period you choose also affects the calculation. If you want payments for life, your monthly amount is lower than if you want payments for exactly 20 years, because the company cannot predict how long you will live but can predict a fixed term precisely. The interest rate environment at the time you purchase matters too: when interest rates are high, insurance companies can earn more on your money, so they can afford to pay you more. When rates are low, payments are lower.

For variable annuities, the calculation also depends on which investments you choose and how they perform. The insurance company typically deducts fees for management and insurance features before calculating your payment.

What happens to your money after you buy an annuity

Once you sign the contract and send money to the insurance company, that money is no longer yours to access freely. The insurance company invests it in bonds, stocks, or other securities depending on the annuity type and your choices. They keep a portion of the investment returns to cover their costs and profit, and they use the rest to fund your payments and build reserves to cover all their annuity obligations.

If you need to access your money before payments begin—or before the contract term ends—you typically face steep penalties. Most annuities include a surrender period, usually 5 to 10 years, during which withdrawals beyond a small annual amount trigger a surrender charge, often 5 to 10 percent of the withdrawal amount. After the surrender period ends, you can usually withdraw money without penalty, but you lose the may provide income stream if you do. Some annuities allow you to withdraw a small percentage each year without penalty, often 10 percent, but this varies by contract.

This illiquidity is a major feature of annuities: they work best for money you are confident you will not need for other purposes. If you might need access to your savings for medical emergencies, long-term care, or other unexpected costs, an annuity may not be the right choice.

Fees and costs vary widely by annuity type

Fixed annuities typically have lower fees than variable annuities. You may pay an upfront commission to the agent or advisor who sells you the annuity—often 3 to 6 percent of your investment—though this is sometimes built into the contract rather than charged separately. Beyond that, fixed annuities often have minimal ongoing fees, though some charge annual administrative fees of $25 to $100.

Variable annuities carry higher costs. In addition to upfront commissions, you pay ongoing annual fees that typically range from 0.5 to 2 percent of your account value for investment management, plus insurance charges for the may provide features. These fees compound over time and can significantly reduce the amount available for your payments. Always ask for a detailed fee schedule before buying any annuity.

Frequently Asked Questions

Can I change my mind after buying an annuity?

Most annuities include a free-look period, usually 10 to 30 days, during which you can return the contract and get your money back with no penalty. After that period ends, you are locked in. If you want out later, you face surrender charges during the surrender period, which typically lasts 5 to 10 years. Some annuities allow penalty-free withdrawals of a small percentage each year, often 10 percent.

What happens to my annuity if the insurance company fails?

Each state has a guaranty fund that protects annuity holders if an insurance company becomes insolvent. Coverage limits vary by state but typically range from $100,000 to $500,000 per person per company. This protection covers the promised payments, not investment performance. Before buying an annuity, you can check the financial strength rating of the insurance company through agencies like AM Best or Moody's.

Do I pay taxes on annuity payments?

Tax treatment depends on how you funded the annuity. If you used pre-tax money from a retirement account like a 401(k) or traditional IRA, your entire payment is taxable as ordinary income. If you used after-tax money, only the earnings portion is taxable; the portion that represents your original investment returns tax-free. Consult a tax professional about your specific situation, as rules vary.

What if I die before annuity payments end?

This depends on the payout option you chose. A life-only annuity stops paying when you die, and any remaining money stays with the insurance company. A life annuity with a period certain—for example, life with 20 years certain—guarantees payments for at least 20 years; if you die before 20 years pass, payments continue to your beneficiary for the remaining period. A joint-and-survivor annuity continues paying a surviving spouse or beneficiary for their lifetime. These options reduce your monthly payment because the insurance company may pay for longer.

How does inflation affect annuity payments?

Fixed annuities do not adjust for inflation, so your purchasing power declines over time. Some annuities offer an inflation-adjustment rider that increases your payment by a set percentage each year, typically 2 to 3 percent, but this reduces your initial payment. Variable annuities may keep pace with inflation if your investments perform well, but payments can also decline if markets fall. There is no perfect solution; you must choose between certainty and inflation protection.
