What a fixed annuity does

A fixed annuity is a contract with an insurance company where you give them a lump sum of money, and they promise to pay you a set amount at regular intervals — usually monthly — for the rest of your life, or for a period you choose. The payment amount never changes, no matter what happens in the stock market or the economy.

You buy the annuity with money you have saved, typically from a retirement account or personal savings. The insurance company invests that money and uses the returns to fund your payments. In exchange, you trade access to that lump sum for predictable income you cannot outlive.

The core appeal is certainty. You know exactly what check arrives each month. You do not have to decide how to invest the money, worry about market downturns, or manage the account yourself. The insurance company bears the investment risk and the longevity risk — the risk that you live longer than expected.

Key Takeaways

  • You pay the insurance company a lump sum once, and they send you the same fixed payment every month for life or a set number of years.
  • The payment rate is locked in when you buy the annuity and does not change, even if interest rates or stock prices move.
  • The insurance company keeps any investment gains beyond what they need to fund your payments, and they absorb any losses.
  • Fixed annuities are backed by the insurance company's reserves, not by government insurance like bank deposits are.
  • You typically cannot access the full lump sum again after you buy the annuity, though some contracts allow small withdrawals or have a death benefit.

How the payment amount is calculated

The insurance company looks at three main things to set your monthly payment: how much money you give them, how old you are when you buy the annuity, and how long they expect to pay you. Older buyers get higher monthly payments because the company expects to pay for fewer years. A 75-year-old buying a $100,000 annuity receives more per month than a 55-year-old buying the same annuity, because the 75-year-old's payments will likely end sooner.

The company also factors in current interest rates. When interest rates are high, the company can earn more on the money you give them, so they can afford to pay you more each month. When rates are low, your monthly payment is lower. This is why the same $100,000 annuity might pay $500 a month in one year and $450 in another year — the rate environment changed between purchases.

The insurance company also builds in a margin for their own costs and profit. They are not passing all investment returns to you; they keep a portion. This margin varies by company and by how much money you invest.

when ready annuities versus deferred annuities

An when ready annuity starts paying you within a few months of purchase. You hand over the money, and the checks begin almost right away. This is the most straightforward type and the one most people picture when they think of a fixed annuity.

A deferred annuity is a contract where you give the insurance company money now, but the payments do not start until later — sometimes years later. During the waiting period, your money sits with the insurance company and may earn a may provide interest rate. Deferred annuities are often used as a savings tool for people who want to lock in a rate today but do not need the income yet. When the payout period finally arrives, it works like an when ready annuity.

Some deferred annuities let you add money over time before payments start. Others are funded with a single lump sum. The terms vary widely by contract, so the specific rules depend on what you purchase.

What happens to your money after you buy

Once you hand over the lump sum, it belongs to the insurance company. They invest it in bonds, mortgages, and other fixed-income securities designed to generate steady returns. You do not own those investments directly and cannot direct how the money is invested. The insurance company's investment team makes all decisions.

The company uses the income from those investments to pay you each month. If they earn more than they need to fund your payments, they keep the extra. If market conditions are poor and returns fall short, they still send you the full payment you were promised — that is their obligation under the contract. This is why the insurance company's financial strength matters; they must have enough reserves to cover all their annuity holders if investments underperform.

You cannot withdraw the full lump sum again. Once the annuity is active, that money is committed to generating your monthly payments. Some contracts allow you to withdraw a small percentage each year without penalty, and most include a death benefit that pays remaining funds to your heirs if you die early. The exact terms depend on the specific contract you purchase.

The trade-off: certainty versus growth

The main advantage of a fixed annuity is that your income is may provide and predictable. You will receive the same payment every month regardless of market performance. This removes investment risk and the need to manage money yourself. For people who want to know exactly what they will receive, this certainty has real value.

The main disadvantage is that your money stops growing once you buy the annuity. If you kept the $100,000 invested in the stock market and the market returned 8 percent annually, your account would grow. With a fixed annuity, your payment is fixed, and any investment gains beyond what you receive go to the insurance company. Over a long retirement, this can mean significantly less total wealth.

Inflation is another consideration. Your $500 monthly payment stays $500 forever. If inflation runs 3 percent per year, that payment buys less and less over time. Some annuities offer inflation-adjusted payments, but those start lower and cost more upfront. Most fixed annuities do not adjust for inflation.

How insurance company strength affects your annuity

A fixed annuity is only as safe as the insurance company backing it. Unlike bank deposits, which are insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000, annuities are not federally insured. Instead, they are backed by the insurance company's own reserves and by state insurance guaranty funds.

If an insurance company fails, your state's guaranty fund typically covers annuity payments up to a limit — often $250,000 per contract, though this varies by state. This is a safety net, not full protection. If you have a very large annuity and the company fails, you could lose money.

Before buying a fixed annuity, check the insurance company's financial ratings through agencies like A.M. Best, Moody's, or Standard & Poor's. These ratings reflect the company's ability to pay claims. A company with a high rating is far less likely to fail. You can also split a large annuity across multiple companies to stay within each state's guaranty fund limits.

Surrender charges and contract terms

Most fixed annuity contracts include a surrender period — a window of time during which you cannot withdraw money without paying a penalty. Surrender periods typically last 5 to 10 years, though they can be shorter or longer. If you need to access your money during this period, the insurance company charges a surrender fee, usually a percentage of the amount you withdraw.

After the surrender period ends, you can typically withdraw money without penalty, though you may still owe taxes on any gains. Some contracts allow you to withdraw a small amount each year — often 10 percent — without triggering the surrender charge.

The surrender period is the insurance company's protection against you taking your money back early. It allows them to invest your funds with confidence that they will have time to earn the returns they promised. Contracts with longer surrender periods often offer slightly higher payment rates because the company has more certainty about how long they will hold your money.

Frequently Asked Questions

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

Most states have a free-look period of 10 to 30 days after you buy an annuity, during which you can cancel and get your full money back with no penalty. After that window closes, you can still withdraw money, but you will pay a surrender charge if you are within the surrender period. The exact terms are in your contract.

What happens to my annuity if the insurance company goes out of business?

Your state's insurance guaranty fund steps in and typically covers your annuity payments up to a limit, often $250,000 per contract. This is not federal insurance like the FDIC, so large annuities may not be fully protected. Buying from a company with strong financial ratings reduces this risk significantly.

Does my fixed annuity payment increase with inflation?

Standard fixed annuities do not adjust for inflation. Your payment stays the same for life. Some companies offer inflation-adjusted annuities where payments rise each year, but these start with a lower initial payment and cost more upfront. You choose which type when you purchase.

Can I leave my annuity to my heirs?

Most fixed annuities include a death benefit that pays remaining funds to your beneficiaries if you die before the contract term ends. The exact amount depends on the type of annuity and the terms you chose. If you bought a life annuity with no period certain, there may be no remaining funds to pass on.

What is the difference between a fixed annuity and a variable annuity?

A fixed annuity pays you a may provide amount each month. A variable annuity lets you choose how to invest the money — usually in mutual funds — and your payment fluctuates based on investment performance. Variable annuities carry market risk but offer growth potential. Fixed annuities trade growth for certainty.
