What Is an Annuity and Should You Consider One?

Annuities are financial products that have a reputation problem — partly because they are often sold through high-pressure sales tactics with significant commissions for the seller, and partly because the products themselves are genuinely complex with many variations that serve very different purposes. Stripped of the sales pitch, an annuity is fundamentally a contract with an insurance company where you provide money — either as a lump sum or over time — in exchange for a stream of payments, either immediately or starting at a future date.

The Basic Concept

At its core, an annuity transfers a specific financial risk — the risk of outliving your savings — to an insurance company in exchange for a fee built into the product's pricing. In its simplest form, you give an insurance company a sum of money, and in return they guarantee to pay you a specific amount for the rest of your life, regardless of how long that turns out to be. This longevity protection is the genuine value proposition that annuities offer, separate from any investment returns.

Immediate vs Deferred Annuities

An immediate annuity begins paying out shortly after you provide the lump sum — commonly used by people entering retirement who want to convert a portion of savings into a guaranteed income stream right away. A deferred annuity delays payments to a future date, during which the money may grow according to the terms of the contract — used by people who want to lock in future income while still working.

Fixed vs Variable vs Indexed Annuities

A fixed annuity provides a guaranteed, predictable payout — similar in concept to a CD but issued by an insurance company with payments often structured for life rather than a fixed term. A variable annuity ties returns to underlying investment subaccounts similar to mutual funds, meaning the payout can fluctuate based on market performance — and typically carries significantly higher fees than fixed annuities. An indexed annuity ties returns to a market index with some downside protection but also caps on upside gains, and is among the most complex and most commonly misunderstood annuity types.

The Fee Structure Concern

Annuities — particularly variable and indexed annuities — often carry fees that are not immediately obvious, including mortality and expense charges, administrative fees, subaccount management fees, and charges for optional riders that add features like guaranteed minimum withdrawals. These fees can total 2 to 4 percent annually or more, which compounds significantly over time and can substantially reduce the actual value received compared to the headline features advertised.

When an Annuity Might Make Sense

For someone who is risk-averse, has no other source of guaranteed lifetime income beyond Social Security, and is concerned specifically about outliving their savings, a simple fixed immediate annuity funded with a portion — not all — of retirement savings can provide genuine peace of mind through guaranteed income that continues regardless of how long retirement lasts. The key word is portion — using an annuity to cover essential expenses alongside Social Security while keeping other savings flexible and accessible is a more balanced approach than converting all retirement savings into an annuity.
