What Is an Annuity? A Practical Guide to Retirement Income
✦ Key takeaways
- An annuity is a contract with an insurer that converts your money into income, often to support retirement.
- It has two phases: an accumulation phase (building value) and a payout phase (receiving income).
- Main types are fixed, variable, and indexed; each can be immediate or deferred.
- Watch the fees, surrender charges, limited liquidity, and the insurer's financial strength before signing.
An annuity is a financial contract between you and an insurance company: you pay them a sum of money, either as a lump sum or in installments, and they promise to return it to you as a steady stream of income in the future. The core idea is to turn a pool of savings into dependable income, which is why annuities are commonly used within retirement plans to help cover living expenses after you stop working.
Annuities appeal to many people because they address real retirement worries: the fear of outliving your money, market volatility, and the difficulty of managing savings by hand over several decades. Yet they are not simple products; contracts can be complex and costly, so it is essential to understand how they work before committing.

How an Annuity Works
An annuity typically moves through two phases. The first is the accumulation phase, when your money is invested and grows over time, either at a fixed rate or linked to the market depending on the contract. The second is the payout phase (annuitization), when the accumulated value is converted into periodic payments that reach you monthly or annually, and which can last for a set number of years or for the rest of your life.
A worked example with illustrative numbers: suppose you are 60 and put $100,000 into an immediate lifetime annuity. You might receive roughly $550 per month (about $6,600 per year) for as long as you live. If you live 25 more years, the total you collect is far more than you paid in; if you pass away early, it may be less, unless the contract includes a death benefit for heirs. These figures are for illustration only and vary by age, interest rates, and the insurer.
The Main Types of Annuities
Annuity contracts differ in how the money grows and how much risk you take. A fixed annuity offers a guaranteed interest rate and predictable income. A variable annuity invests your money in portfolios similar to mutual funds, so returns rise or fall with the market. An indexed annuity ties returns to the performance of a market index, such as a stock index, usually with a floor for protection and a cap that limits the upside.
In terms of timing, an immediate annuity begins paying income shortly after you hand over the money (suited to those on the edge of retirement), while a deferred annuity grows for years before payments begin later (suited to those planning ahead).
| Type | How money grows | Risk level | Income predictability |
|---|---|---|---|
| Fixed | Guaranteed interest | Low | High |
| Variable | Performance of chosen investments | High | Low |
| Indexed | Linked to an index with limits | Medium | Medium |
Pros, Cons, and Fees
Key advantages include income that can last for life, protection against the risk of outliving your savings, and tax-deferred growth in many systems. Drawbacks include limited liquidity and difficulty withdrawing money without penalties, the complexity of the contracts, and sometimes high fees that can meaningfully reduce your real return.
Fees to watch include surrender charges for withdrawing during the early years, annual administrative fees, mortality and expense charges in variable contracts, and charges for optional add-ons (riders) such as a guaranteed minimum income. Add these costs up, because together they can reach an annual percentage that affects value over the long term. Remember, too, that income guarantees rest on the financial strength of the insurer itself.
Who an Annuity May Suit
An annuity may suit someone nearing retirement who wants steady income to cover basic expenses, someone worried about market swings who prefers stability, or someone without another guaranteed source of retirement income. On the other hand, it may not suit those who need high flexibility to access their money, those with a short time horizon, or those who can meet their goals with simpler, lower-cost tools.
