Do you need an annuity? Guaranteed income and the retirement income floor
An annuity, stripped of the sales pitch and the jargon, is simply a pension you buy: you hand over a lump sum, and an insurer pays you a guaranteed income for life. Used well, it builds an “income floor” that covers your essentials no matter what the market does. Used carelessly, it locks up money you can’t get back. Here’s how to tell the difference — and why federal retirees often already own the best annuity there is.
1. The income floor: the simplest plan that works
There’s a retirement strategy so simple it barely needs a spreadsheet: guarantee your essentials, then invest the rest. It’s called flooring, and the idea is to cover your non-negotiable expenses — housing, food, utilities, insurance, healthcare — with income that is guaranteed for life and immune to the market. Whatever’s left over funds your discretionary spending and stays invested for growth.
The power of this approach is as much emotional as financial. When your survival expenses are locked in for life, a 30% market crash becomes a threat to your travel budget, not to your ability to eat and pay the mortgage. That changes how you behave: floored retirees are far less likely to panic-sell, which is itself one of the biggest determinants of long-term success. Social Security is the first floor everyone has. A pension is a second. An annuity is how you buy more floor when those two aren’t enough.
Cover what you must pay with income you can’t outlive; invest the rest. The bigger your guaranteed floor, the more market risk you can comfortably take with everything above it.
2. What an annuity actually is
Behind the confusing product names, the core annuity is simple. A single premium immediate annuity (SPIA) is a contract where you give an insurance company a lump sum, and it sends you a guaranteed check every month for the rest of your life — usually starting within a year. It is, functionally, a personal pension: predictable, contractual, and unaffected by markets. Once issued, your lump sum is converted into the income stream; you give up access to the principal in exchange for income you cannot outlive. That trade — liquidity for longevity protection — is the whole deal.
A few variations are worth knowing, but most retirees only need the first:
| Type | What it does | Watch for |
|---|---|---|
| SPIA (immediate) | Lump sum now → income starts within a year. The simplest, lowest-cost, most transparent option. | Irreversible; no ongoing fees. |
| DIA / QLAC (deferred) | Lump sum now → income starts years later (e.g., at 80+). Higher payout for the wait; a QLAC inside an IRA can also reduce RMDs. | Longevity insurance, not near-term income. |
| MYGA | A fixed-rate annuity, like a multi-year CD. Top 2026 rates around 4.75–5.25%. | Growth, not lifetime income. |
| Variable / Indexed | Market-linked annuities with optional income riders. | Annual fees of 1–3%; complex. Easy to oversell. |
For building an income floor, the SPIA is the workhorse. The variable and indexed products carry high fees and complexity that the simple flooring goal doesn’t require — don’t let a SPIA conversation get steered into one.
3. Why annuities can out-pay bonds: mortality credits
Here’s the part that surprises people: a 65-year-old SPIA can pay out more each year than a bond portfolio of the same size, even though the insurer invests in bonds. The secret is mortality credits. When thousands of retirees pool their money in an annuity, some die earlier than expected and some later. The money from those who die early subsidizes the payments to those who live long. You can’t replicate that pooling on your own — it’s the one thing self-managing a portfolio fundamentally can’t do.
This is why a payout rate is not an interest rate. A 7% payout on $100,000 isn’t 7% interest; it blends interest, a return of your own principal, and those mortality credits, which is why you shouldn’t compare it head-to-head with a bond yield. The mortality credit is also why annuities get more efficient the older you buy — and why they’re the single most effective tool ever invented for the specific risk of living a very long time.
4. The 2026 payout landscape
Annuity payouts move with interest rates, and after years of near-zero rates, 2026 is one of the more attractive environments in two decades. As of early 2026, a 65-year-old buying a life immediate annuity might see a payout rate around 6.5% to 7.5% — roughly $600 to $700 a month per $100,000 — with older buyers getting more. A 70-year-old can see payout rates approaching 8.5%, and a 73-year-old around 8%.
Two cautions shape any 2026 purchase. First, inflation: a fixed payment that looks generous today buys noticeably less in 15 years, and adding a cost-of-living rider cuts the starting payment by 20–30% or more — so many advisors prefer a flat SPIA paired with a separate growth portfolio to handle inflation later. Second, shop hard: for the identical deposit, one A-rated carrier may pay materially more than another, a difference that compounds for life. Quotes are free; the spread between carriers is not.
5. Build your income floor
The calculator below shows whether you even have a gap to fill, and if so, roughly what it would cost to close it with an annuity. Enter your essential annual spending, the guaranteed income you already have (FERS pension plus Social Security), your investable portfolio, and an assumed payout rate. It estimates the lump-sum premium to guarantee the gap — and how much of your portfolio would be left invested.

A rough, educational illustration using a flat payout rate in today’s dollars — not a quote, a recommendation, or personalized advice. Real annuity income depends on your age, sex, carrier, state, and options. Warrior Retirement does not sell annuities; get quotes and guidance from a fiduciary before acting.
6. The federal employee’s huge head start
If you’re a federal retiree, read this section before you ever take an annuity sales call. You already own one of the best annuities money can buy: the FERS pension. It’s an inflation-adjusted, lifetime, government-backed income stream — exactly what private-sector retirees pay insurers tens of thousands of dollars to approximate. Combined with Social Security, it gives most federal retirees a substantial guaranteed floor before they spend a dollar on a commercial product.
That changes the order of operations. Before buying any annuity, a federal retiree should first maximize the cheap floor they already have:
| Cheaper floor to build first | Why it usually beats buying a SPIA |
|---|---|
| Delay Social Security to 70 | Each year of delay permanently raises an inflation-adjusted, government-guaranteed benefit — the best-value “annuity” available, with no insurer credit risk. |
| The TSP life annuity option | The TSP lets you convert part of your balance into lifetime income through its annuity provider — worth comparing against outside quotes. |
| Your FERS pension itself | Already guaranteed and COLA-adjusted; for many retirees, the pension plus Social Security already covers the essentials. |
Only after exhausting those cheaper options does a commercial annuity earn a look — and then only to close a remaining gap between your guaranteed income and your essential spending. Run the calculator above with your real pension and Social Security numbers; many federal retirees discover the gap is small or zero, which means the answer to “do I need an annuity?” is often “you already have one.”
Federal retirees are a favorite target for annuity sales pitches precisely because they have TSP balances to roll over. Before moving TSP money into any insurance product, compare it against simply delaying Social Security and using the TSP’s own annuity — and never let anyone rush an irreversible decision.
7. The real downsides
Annuities are oversold, and a fair article has to be honest about why caution is warranted. The genuine drawbacks:
| Downside | What it means |
|---|---|
| Irreversible & illiquid | Once you annuitize a basic SPIA, the lump sum is gone — no access for a roof, a medical bill, or an emergency. |
| Little or nothing for heirs | A life-only SPIA stops paying at death. A refund or period-certain feature protects heirs but lowers your income. |
| Inflation erosion | Fixed payments lose purchasing power over decades; the inflation rider that fixes this cuts your starting payout 20–30%+. |
| Insurer credit risk | Backed by the insurer plus state guaranty associations (typically ~$250k per person, per insurer) — not FDIC. Split large amounts and buy only top-rated carriers. |
| Taxes | Annuity income is taxed as ordinary income, not at lower capital-gains rates; it can also push up your Medicare IRMAA tier. |
| Fees on complex products | Variable and indexed annuities carry 1–3% annual fees. A plain SPIA has none — don’t confuse the two. |
8. Rules of thumb if you do buy
If, after building the cheap floor, a gap remains and an annuity makes sense, a handful of disciplines separate a smart purchase from a regrettable one:
Cap it at 30–50% of your portfolio. Annuitizing everything removes all flexibility; annuitizing less than 30% rarely moves the income needle. Ladder your purchases across several ages — buying in pieces at 65, 68, and 72 catches different rate environments and higher payouts as you age. Buy only the strongest carriers, and split amounts above the guaranty-association limit across two insurers. Get multiple quotes — the same deposit can pay meaningfully different income at different companies. And match the payout option to your life: single-life pays the most, but a joint or period-certain option protects a spouse or heirs. Above all, never rush; a reputable annuity will still be available next month.
For a federal retiree, the right order is: maximize Social Security and your FERS pension first, fill any remaining essentials gap with a modest, laddered SPIA from a top carrier, and keep the rest invested for growth and flexibility.
9. Frequently asked questions
What is an income floor in retirement?
An income floor is the layer of guaranteed, lifelong income that covers your essential expenses — housing, food, utilities, insurance, and healthcare — no matter what the stock market does. The strategy, sometimes called flooring, is to cover those essentials with guaranteed sources like Social Security, a pension, and annuities, and then invest the rest of your savings for growth and discretionary spending. The appeal is psychological as much as financial: when your survival expenses are guaranteed for life, a market crash threatens your vacations and extras, not your ability to eat and keep the lights on.
What is a single premium immediate annuity (SPIA)?
A single premium immediate annuity, or SPIA, is the simplest and most transparent annuity. You hand an insurance company a one-time lump sum, and in exchange it sends you a guaranteed payment every month for the rest of your life, usually starting within a year. It functions like a pension you buy for yourself: predictable, contractual, and unaffected by the market. Once issued, the lump sum is converted into income and you generally can’t get it back, which is the central trade-off — you give up access to the principal in return for income you cannot outlive. Unlike variable and indexed annuities, SPIAs carry no ongoing investment fees.
How much income does an annuity pay in 2026?
As of early 2026, a 65-year-old buying a life immediate annuity might receive a payout rate of roughly 6.5% to 7.5% per year per dollar of premium, or about $600 to $700 a month per $100,000. Older buyers receive higher rates because their life expectancy is shorter. Important: a payout rate is not an interest rate — it blends interest, your own returned principal, and mortality credits, so you can’t compare it directly to a bond yield. Rates also vary widely between insurers for the identical deposit, so getting multiple quotes matters. Adding an inflation adjustment lowers the starting payment substantially, often by 20% to 30%.
Do federal retirees need to buy an annuity?
Often not, and that’s the federal advantage. The FERS pension is already an inflation-adjusted annuity, and combined with Social Security it forms a large guaranteed income floor that most private-sector retirees have to build from scratch. Before buying any annuity, a federal retiree should first maximize the floor they already have: delaying Social Security to age 70 buys more guaranteed, COLA-adjusted income at the best value available, and the TSP itself offers a life-annuity option. Only after maxing those cheaper sources does it make sense to consider a commercial annuity, and only to close a remaining gap between guaranteed income and essential spending.
What are the biggest downsides of annuities?
The main drawbacks are illiquidity, inflation, and credit risk. A basic immediate annuity is irreversible — once you annuitize, you can’t get the lump sum back for an emergency, and without a refund or period-certain feature there may be nothing left for heirs. Fixed payments lose purchasing power to inflation over time, and adding a cost-of-living rider sharply reduces the starting payout. The income is only as safe as the insurer, backed by the company plus state guaranty associations that typically cover around $250,000 per person per insurer, so large amounts should be split across carriers. Finally, complex variable and indexed annuities carry high annual fees and should not be confused with the simple, low-cost SPIA.
