Quick Answer
An annuity is a contract with an insurance company that converts a lump sum into guaranteed income — either for a set period or for life. In retirement, annuities work best as an income floor: covering essential expenses so your investment portfolio doesn't have to, giving you the freedom to invest the rest for growth without panic-selling during downturns.
The core problem annuities solve is longevity risk — the very real possibility of outliving your savings. No other financial product besides Social Security and a pension guarantees income for as long as you live, regardless of market performance or how long that turns out to be.
There are several types of annuities, and they work very differently. A fixed annuity pays a set interest rate on your principal — predictable and safe, but doesn't participate in market growth. A fixed indexed annuity (FIA) links growth potential to a market index like the S&P 500, with a floor that protects against losses — you participate in some upside without risk of losing principal. A variable annuity invests in market subaccounts and carries real market risk — often comes with high fees and is less appropriate for most retirees. An income annuity (also called a SPIA or deferred income annuity) converts a lump sum into guaranteed lifetime payments — the purest form of longevity protection.
The right role for an annuity in a retirement plan is specific: cover your income gap. If your essential monthly expenses are $5,000 and Social Security provides $2,500, you have a $2,500/month gap. An annuity can fill that gap with guaranteed income for life — freeing your investment portfolio to focus on growth and discretionary spending rather than survival.
Annuities are not for everyone and not for every dollar. Putting all your retirement savings into an annuity sacrifices liquidity and growth potential. The best use is strategic — allocating a portion of your assets to create a guaranteed income floor while keeping the rest invested for inflation protection and flexibility.
Fees, surrender charges, and contract terms vary widely. An annuity that's right for one person can be completely wrong for another. This is a product that requires professional guidance — not a sales pitch.
Fixed Annuity: Pays a guaranteed interest rate for a set period. Simple, predictable, and safe — but growth is limited and doesn't keep pace with inflation over long retirements. Best for short-term income stability or as a CD alternative.
Fixed Indexed Annuity (FIA): Growth is linked to a market index with a floor of zero — you can't lose principal due to market drops. Offers higher growth potential than a fixed annuity while protecting your core retirement income. One of the most popular tools for creating a protected income floor.
Variable Annuity: Invested in market subaccounts — carries real market risk and typically high fees. Can lose value. Generally not recommended for retirees seeking income security unless very carefully structured with appropriate riders.
Single Premium Immediate Annuity (SPIA): You hand over a lump sum and immediately start receiving guaranteed monthly income for life. Simple, transparent, and powerful for retirees who need income now and want longevity protection.
Deferred Income Annuity (DIA): You purchase now, income starts at a future date — for example, at age 80. Locks in a higher payout rate and acts as longevity insurance, ensuring income even if you live well into your 80s and 90s.
Real-Life Example
Dennis retired at 68 with $750,000 in savings and $2,100/month in Social Security. His essential monthly expenses were $4,800 — leaving a $2,700/month gap his portfolio needed to fill. Withdrawing $32,400/year from savings was manageable, but every market downturn made him anxious he'd be forced to sell at a loss. We allocated $220,000 into a fixed indexed annuity with a lifetime income rider, generating $2,650/month guaranteed for life. His essential expenses were now fully covered by guaranteed income. His remaining $530,000 stayed invested for growth and discretionary spending — and he stopped watching the market every day. The guaranteed floor changed everything about how he experienced retirement.
