An annuity is a contract with an insurance company: you hand over a lump sum or a series of payments, and in exchange, the insurer agrees to pay you back on a schedule, sometimes for a set period, sometimes for the rest of your life. That structure makes annuities one of the few financial products that can guarantee income you can’t outlive, which is exactly why they show up in retirement income planning.
Part of our guide: Retirement Planning.
The five main types
Fixed annuities pay a set interest rate and a predictable income, which suits conservative investors who want stability more than growth. The tradeoff is limited upside, and inflation can erode purchasing power over a long retirement.
Variable annuities tie your payments to the performance of underlying investment options like mutual funds. That gives you real growth potential, but payments aren’t guaranteed and can fall, and fees tend to run higher than other annuity types.
Indexed annuities link returns to a market index such as the S&P 500 while offering some protection against losses. Returns are usually capped in exchange for that downside protection, and the fee structures can get complex.
Immediate annuities start paying out shortly after you fund them, which works for retirees who need income right away. There’s no accumulation phase and no growth potential, and the purchase is generally irrevocable.
Deferred annuities let your investment grow tax-deferred until payments begin at a future date, which suits someone with time before they need the income. Early withdrawal usually triggers penalties, and the structure requires a longer commitment.
What annuities actually solve
The core benefit is longevity protection: an annuity can keep paying you as long as you live, addressing the real risk of outliving your other savings. Fixed annuities in particular offer predictable payments for covering essential expenses like housing and healthcare, so market volatility doesn’t touch the money you need for basics. Deferred annuities add tax-deferred growth on top of that, which can matter for long-term planning.
Where the drawbacks show up
None of that comes free. Variable and indexed annuities in particular can carry high fees that eat into returns over time. Annuities are also illiquid: early withdrawal usually triggers penalties, so money committed to an annuity isn’t available the way a brokerage account is. And the terms, especially on indexed and variable products, can be genuinely hard to parse without help.
How they fit into a broader plan
Annuities work best as one piece of a retirement income plan, not the entire plan. A reasonable structure uses an annuity to cover fixed essential expenses, then layers Social Security, pensions, and investment income on top for the rest. For someone who is risk-averse or specifically worried about outliving their savings, that combination can provide real peace of mind. Before committing any capital, it’s worth working through the fee structure, the payout terms, and the surrender period with a professional who can walk you through how a specific product actually behaves under different market conditions.
