A life insurance annuity is a contract where you pay a lump sum or series of payments to an insurance company, and they pay you a may provide income for a set period or for the rest of your life.

The insurance company takes your money upfront, invests it, and then sends you regular checks — monthly, quarterly, or annually — based on the terms you chose. Unlike a traditional life insurance policy that pays your beneficiaries when you die, an annuity pays you while you're alive. The payments stop when you pass away, though some annuities let you name a beneficiary to receive remaining funds.

Annuities are often bought with money from a life insurance payout, a 401(k) rollover, or savings. They're designed to solve a specific problem: how to turn a large sum of money into steady income you can't outlive. That predictability appeals to retirees who want to know exactly what they'll receive each month.

Key Takeaways

  • An annuity converts a lump sum into regular payments over time, either for a fixed period or for your entire life.
  • Fixed annuities pay the same amount every period; variable annuities tie payments to investment performance and carry more risk.
  • Immediate annuities begin payments within a year; deferred annuities delay payments so your money can grow first.
  • Annuities charge fees for administration, investment management, and riders (optional add-ons), which reduce your actual payout.
  • Once you buy an annuity, you typically cannot get your money back or change the terms, so the decision is permanent.

Fixed annuities versus variable annuities

A fixed annuity pays you the same amount every month or quarter for life or a set number of years. The insurance company guarantees the payment amount when you sign the contract. If you buy a fixed annuity for $100,000 at age 65, the company might promise you $500 per month for life. That $500 never changes, regardless of inflation or how the economy performs. The insurance company bears the investment risk — they have to pay you even if their investments underperform.

A variable annuity ties your payments to the performance of investments you choose, usually mutual funds. If those investments gain value, your payments increase. If they lose value, your payments drop. You take on the investment risk instead of the insurance company. Variable annuities often come with a may provide minimum payment, so you won't fall below a certain floor, but your upside is also capped by how well the underlying investments perform.

Fixed annuities appeal to people who want certainty and can't afford payment swings. Variable annuities appeal to people who believe they can beat inflation through investment growth and are comfortable with fluctuation.

Immediate annuities and deferred annuities

An immediate annuity starts paying you within a year of purchase — often within a month or two. You hand over a lump sum, and the insurance company begins sending checks right away. Immediate annuities are common for people who have just retired and need income now.

A deferred annuity delays payments. You buy it years before you need the income, and your money grows (either at a fixed rate or tied to investments) until you decide to start withdrawals. Deferred annuities let you accumulate more money before payments begin, which means larger monthly checks later. They're often used by people in their 50s who want to lock in a payment amount for age 70 or 75.

The trade-off is simple: immediate annuities pay you sooner but on a smaller lump sum. Deferred annuities pay you later but on a larger accumulated balance.

How annuity payments are calculated

The insurance company uses three main factors to set your payment amount: your age when payments start, your life expectancy (based on actuarial tables), and current interest rates. Older buyers receive higher monthly payments because the company expects to pay them for fewer years. A 75-year-old buying a $100,000 immediate annuity will receive more per month than a 65-year-old buying the same annuity, because statistically the 75-year-old has fewer years left.

Interest rates also matter. When interest rates are high, insurance companies can invest your money at higher returns, so they can afford to pay you more. When rates are low, your payments shrink. This is why the timing of an annuity purchase affects the outcome — buying during a high-rate environment locks in better payments.

You can also choose different payout structures. A life-only annuity pays you for as long as you live, then stops — the insurance company keeps any remaining balance. A period-certain annuity guarantees payments for a set number of years (10, 20, 30) regardless of whether you're alive. A joint-and-survivor annuity continues paying your spouse or beneficiary after you die, but your monthly payment is lower because the company expects to pay for two lifespans instead of one.

Fees and costs embedded in annuities

Annuities are not free. The insurance company deducts fees before calculating your payment, which means you receive less than your lump sum would suggest. Common fees include:

  • Mortality and expense risk charge: The company's cost to may provide your payments and manage the risk that you live longer than expected. This typically runs 0.5% to 1.5% per year of your account balance.
  • Administrative fees: Costs to process paperwork, send statements, and manage your account. These range from $25 to $100 per year or a percentage of your balance.
  • Investment management fees (variable annuities only): Charges for managing the mutual funds or investment options you choose. These can range from 0.5% to 2% annually.
  • Rider fees: Optional add-ons like inflation protection, long-term care riders, or death benefit guarantees cost extra — sometimes 0.25% to 1% per year.

These fees compound over time. A variable annuity with a 1% mortality charge, 0.5% administrative fee, 1% investment fee, and 0.5% rider fee totals 3% annually. On a $100,000 annuity, that's $3,000 per year in costs before you receive a single payment. Always ask the insurance company or agent for a written fee schedule before you buy.

The permanence of an annuity purchase

Once you buy an annuity and payments begin, you typically cannot undo the decision or change the terms. The money is gone — you've traded a lump sum for a stream of payments. If you need access to the full balance later, you're out of luck. Some annuities allow you to withdraw a small percentage per year without penalty, but most lock your money away.

This permanence is why annuities require careful thought. If you buy an annuity at 65 and then face a major medical expense at 70, you cannot simply cash out. You're committed to the payment schedule you chose. Some people buy a partial annuity — using part of their savings for may provide income and keeping the rest liquid for emergencies — to balance security with flexibility.

Surrender charges also apply if you try to exit early. These penalties can be 5% to 10% of your balance in the first few years, declining over time. After 7 to 10 years, surrender charges usually disappear, but by then you've already committed to the annuity's terms.

Who benefits from annuities and who should avoid them

Annuities work best for people who have a large lump sum, want predictable income they can't outlive, and don't need access to the principal. Retirees with pensions and Social Security who want additional may provide income, or people who inherit a substantial sum and need it to last, are common buyers.

Annuities are less suitable if you're young and healthy (you have decades to invest and grow wealth), if you need liquidity and flexibility, if you're uncomfortable with high fees, or if you have significant debt. They're also a poor fit if you're buying with borrowed money or if you don't fully understand the terms.

Some people are sold annuities by agents who earn high commissions (sometimes 5% to 10% of the purchase price), which creates a conflict of interest. Always get a second opinion from a fee-only financial advisor before committing to an annuity, especially if the agent is pushing you to buy quickly.

Frequently Asked Questions

Can I change my mind after buying an annuity?

Most annuities have a free-look period of 10 to 30 days after purchase, during which you can return it for a full refund. After that window closes, you're locked in. Some annuities allow partial withdrawals or have surrender charges if you exit early, but you cannot simply reverse the purchase.

What happens to my annuity if I die before payments end?

It depends on the payout structure you chose. A life-only annuity stops and the remaining balance stays with the insurance company. A period-certain or joint-and-survivor annuity continues paying your beneficiary for the remaining term or their lifetime. Always name a beneficiary and understand what happens after you die before you buy.

Are annuities taxed differently than other income?

If you buy an annuity with pre-tax money (like a 401(k) rollover), your entire payment is taxed as ordinary income. If you buy with after-tax money, only the earnings portion is taxed; the principal portion is tax-free. Consult a tax professional about your specific situation, as rules vary based on how you funded the annuity.

How do annuities compare to bonds or dividend-paying stocks?

Annuities may provide a payment amount and last for life (if you choose that option), while bonds and stocks fluctuate and require you to manage the investments. Annuities cost more in fees but offer certainty. Bonds and stocks offer more flexibility and lower costs but no may provide of income or principal.

Can I use a life insurance payout to buy an annuity?

Yes. Many beneficiaries receive a lump-sum life insurance payout and use it to purchase an immediate annuity, converting the one-time payment into steady income. This is a common strategy for surviving spouses who need reliable cash flow. The insurance company and the annuity company are often the same firm, making the process straightforward.
